Creating a new Mold Product A Mold Product is a standard CATIA V5 Product where specific Mold elements will be inserted later :

You can create a new CATIA V5 product by : Starting workbench Mold Tooling Design :

Or explicitly creating a new Product :

A new Product is created

Copyright DASSAULT SYSTEMES 2002

18

Inserting the Molded Part in the Mold Product The Molded Part can be created in the Mold Product by inserting the already existing CATPart : From the contextual menu of the top Product : Components / Existing Component, then selecting the name of the CATPart file Or by using standard menu Insert / Existing Component…, , then selecting the name of the CATPart file

The Molded Part is inserted in the Product

Copyright DASSAULT SYSTEMES 2002

19

Structure of the Molded Part (1/3) : Requirements

Its Part Number (see tab Product in contextual menu Properties) must be MoldedPart You can define as you wish the Instance name and the name of the CATPart file

Copyright DASSAULT SYSTEMES 2002

20

Structure of the Molded Part (2/3) : Requirements

The Molded Part must contain the part itself and also all the surface elements required for core/cavity separation. It is generally created as the result of the preparation work done in workbench Core & Cavity Design. The Molded Part should contain the following elements, in an open body called PartingBody : PartingSurface : the parting surface around the Molded Part, created from the parting line CoreSurface : Join of the core side of the part and of PartingSurface CavitySurface : Join of the cavity side of the part and of PartingSurface The elements bearing these names will be used by the application as default elements (editable) for core/cavity split operations and for creating gates and runners. If they are not present, you will have to explicitly select other elements in the Molded Part when performing core/cavity split operations. Copyright DASSAULT SYSTEMES 2002

21

Structure of the Molded Part (3/3) : Example PartingSurface The Core Side may come from any operation (CCV Define Pulling direction, GSD Extract, …)

Filling Holes

Filling Holes may come from any filling operation done in GSD or CCV

Copyright DASSAULT SYSTEMES 2002

CoreSurface = PartingSurface + Core Side + Filling Holes CavitySurface = PartingSurface + Cavity side + Filling Holes

22

Creating the Mold Base (1/4)

You can define a new Mold Base by : Defining entirely the set of plates with their dimensions Or selecting an existing Mold Base in a catalog

Copyright DASSAULT SYSTEMES 2002

23

Creating the Mold Base (2/4) You can create a new Mold Base by defining entirely the number, types and dimensions of the plates : The default Mold Base configuration includes all the different types of plates, with default values for their dimensions. You may deactivate some of them (except Core and Cavity, which are mandatory), or modify on the fly each dimension depending on your design needs. Function Create a new Mold allows you to create a new Mold Base

• Mandatory plates are shaded in the panel and cannot be deactivated • Optional plates can be deactivated : the preview of the Mold Base is then automatically updated

Mold Base dialog Box lets you control the definition of the plates to include in the Mold Base

Copyright DASSAULT SYSTEMES 2002

24

Creating the Mold Base (3/4) You can also select an existing Mold Base variant in a catalog 1 3 2

When you select a Mold Base variant, its dimensions (Length and Width) are pre-visualized in the 3D viewer

Once you have selected your Mold Base, a full preview is displayed

Copyright DASSAULT SYSTEMES 2002

The new Mold Base has been created as a new Product inside the top Product 25

Creating the Mold Base (4/4) Structure of the resulting Mold Product Once the Mold Base has been created, the overall structure of the Mold Product is made up of :   

A top Product including the following two elements : A Component corresponding to the Molded Part Another Product corresponding to the Mold tool assembly itself, containing the Mold Base plates, and where other components will be later inserted. This Product is structured into 3 main sub-assemblies : InjectionSide, EjectionSide and EjectorSystem

Mold Product Component Molded Part

Mold Base product

Sub-assemblies

Copyright DASSAULT SYSTEMES 2002

26

Additional Information… Creation of the Molded Part : If the Mold Base is created prior to inserting the existing CATPart file corresponding to the Molded Part, a new empty Component named Molded Part will be automatically created by application Mold Tooling Design This component can then be interactively completed, using standard Part Design, Core&Cavity Design, Generative Shape Design and Assembly Design functions

It can also be further replaced, using contextual menu function Components… / Replace Component

Copyright DASSAULT SYSTEMES 2002

27

Positioning the Molded Part

You can use function Snap to snap the local axis system of the Molded Part, if it has one, onto the local axis system of the Mold Base, located at the bottom of the Core Plate. You can also use main planes for snapping purposes. You can also use the Compass to dynamically move the Molded Part in order to ensure that the Parting Surface will fully split Core and Cavity plates, or to define precise location values. You can for example snap the Compass to the local axis system of the Molded Part or to the Parting Surface, in order to drag it as desired.

You can also use function Manipulation to position the Part Copyright DASSAULT SYSTEMES 2002

Editing the Mold Base You will see how to edit the definition of a Mold Base.

Editing the definition of the existing Mold Base Adding a Plate Splitting Core and Cavity Plates

Copyright DASSAULT SYSTEMES 2002

30

Editing the definition of the existing Mold Base (1/2) It is possible to update in various ways the definition of the current Mold Base by using contextual menu function MoldEdition : You can select another Mold Base reference in the Catalog

You can browse the Design Table containing the list of Mold Base variants and select a new one

Copyright DASSAULT SYSTEMES 2002

31

Editing the definition of the existing Mold Base (2/2) In menu MoldEdition, it is also possible to : Update the dimension of some plates (either mandatory like CorePlate, or optional ones, like the CoreSupportPlate)

Remove optional plates by unselecting them in the panel

Copyright DASSAULT SYSTEMES 2002

32

Adding a Plate It is possible to add a plate inside an existing Mold Base. The new plate must be of one of the predefined available types allowed for the current Mold Base. Current limitation : it is not possible to add other types of plates (userdefined types of plates) The Mold Base preview is updated with the selected plate

Only types allowed for the current Mold Base are displayed

Note that it is not possible to modify parameters which are related to the overall size of the Mold Base Copyright DASSAULT SYSTEMES 2002

Once created, the new plate is inserted in the tree structure 33

Splitting Core and Cavity Plates Core and Cavity Plates must be split to fit the shape of the Molded Part For both Core and Cavity plates, there is a dedicated function Split Component… in their contextual menu.

The application will use by default as splitting surface the one named CoreSurface (resp. CavitySurface), if present in the Molded Part. You can select another surface if you wish.

Copyright DASSAULT SYSTEMES 2002

34

Exercise Presentation And now practice on Step 2 of the Master Exercise, to learn about : Splitting Core and Cavity Plates

35

Creating Components You will learn how to select and instantiate any type of component in a Mold.

Selecting a Component in a catalog Instantiating and Positioning a Component

Copyright DASSAULT SYSTEMES 2002

36

Selecting a Component in a Catalog (1/2) The procedure to select, then position a component is similar for all the available types of components (Leader Pin, Bushing, Locating Ring, Cap Screw, …). You first have to select the desired reference in a catalog : Click the icon corresponding to the desired type of component Select the desired catalog provider : DME, Hasco, Rabourdin, etc. Select the desired reference for this component

Double-click the desired provider name to select it

Copyright DASSAULT SYSTEMES 2002

Double-click the desired reference to select it

37

Selecting a Component in a Catalog (2/2) Then select the appropriate variant for this reference, depending on the dimensions required : Note that if Selection / Filter is active in Tools / Options / Mechanical Design / Mold Tooling Design (default setting), a knowledge rule is applied to filter only the relevant dimensions. This knowledge filter is specific to each type of component (please refer to the on-line documentation for the exhaustive description of these rules). You can erase the proposed filter if you want to see the whole list. Select the desired variant in the list

By default, the relevant filter for the current type of component is applied

Copyright DASSAULT SYSTEMES 2002

Double-click the desired variant to select it

38

Positioning a Component (1/7) Once you have selected the desired variant of the component, the corresponding definition panel for this type of component is displayed. The first method available to position the component is to pick an existing 3D point in the Mold Base : Note that if you have selected a Mold Base from a standard catalog, several 3D points are present in this Mold Base, corresponding to the positions recommended by the provider for the different types of components. For example, the 3 three points displayed with a round marker in the corner of the Mold Base are intended for the positioning of guiding elements (Leader Pin, Bushing, Sleeve).

Predefined points for guiding components

You can also use a 3D point created beforehand using for example workbench Wireframe and Surface Copyright DASSAULT SYSTEMES 2002

39

Positioning a Component (2/7) Once you have picked the 3D point, a preview of the component is displayed, and you can now adjust precisely its position by entering proper values for Instance Origin, either by entering numerical values (absolute : X,Y,Z, or local : U,V,W), or by using the green arrows displayed in the viewer (for translation) or the green half-circle (for rotation). Button Reverse Component allows to invert Z orientation if needed Option Associated (active by default) will create an offset constraint between the component and the selected position, thus ensuring that the component cannot be moved independently from its reference 3D point.

Predefined point included in the Mold Base

Copyright DASSAULT SYSTEMES 2002

Numerical values and arrows positions are updated simultaneously 40

Positioning a Component (3/7) Fields Drill From and To in tab Positioning allow to define the first and last plates to be drilled by the component when it is inserted in the Mold Base. The plates are automatically drilled by the application when validating creation.

The plates to be drilled can be selected directly in the viewer or in the tree.

Copyright DASSAULT SYSTEMES 2002

41

Positioning a Component (4/7) Note that Mold Bases coming from catalogs of standard providers contain predefined sets of points, automatically recognized by the application when inserting a given type of component (automatic multi-instantiation). Note that this is done only if option Preview All is active. For example, when picking one of the points dedicated to the positioning of Leader Pins, the corresponding additional instances of the Leader Pin are automatically positioned on the other predefined points.

The current instance is highlighted in red. You can cancel one instance by just picking the W axis in its preview.

Manual multi-instantiation : it is possible to multi-instantiate any given component in a single operation : you just have to pick several positioning points instead of one. Copyright DASSAULT SYSTEMES 2002

42

Positioning a Component (5/7) When validating the creation (single- or multi-instantiation), the resulting component(s) is (are) created in the Mold Base, together with the corresponding holes in the impacted plates. The new component is created in the specification tree, in the sub-assembly where the plate specified as Drill From belongs.

Copyright DASSAULT SYSTEMES 2002

43

Positioning a Component (6/7)

A second method available to position a component is to pick a planar face of a plate (or another component), where you can further precisely adjust the desired position for the component. The application then switches to mode Work on plane and the grid is displayed (you can use standard sketcher option Snap to point if you wish).

Copyright DASSAULT SYSTEMES 2002

44

Positioning a Component (7/7)

You can then : either pick a point on the face, or pick a point outside the face : the application will automatically project this point onto the face, or select a point in a sketch on the face, or select a point in a sketch outside the face : the application will automatically project this point onto the face, or select an existing edge or line which intersects the face : the application will automatically compute the intersection point, or select the axis of an existing component (this axis will be displayed when hovering the mouse over the component). Note in this case that this is just a positioning capability and does not implicitly create a concentricity constraint between the existing component and the new one.

Once the position of the component has been determined, you can proceed for the other parameters as described in the positioning method based on a 3D point.

A third method available to position components is to use a sketch of points, for example to instantiate in a single shot many components of the same type. Copyright DASSAULT SYSTEMES 2002

45

Additional Information… When positioning a component, you can apply not only translation movements, but you can also define a rotation by using the green circle arc displayed in the preview : Either by dragging this arc : it will rotate the component accordingly, Or by selecting MB3 while this arc is selected (highlighted in orange) : contextual menu Edit angle will be displayed, allowing to rotate the component by increment steps of the displayed value

Copyright DASSAULT SYSTEMES 2002

46

Exercise Presentation And now practice on Step 3 of the Master Exercise, to learn about : Selecting Components Instantiating and Positioning Components

47

Editing Components You will see how to modify the definition of a component, how to fit its shape to Core and Cavity requirements if needed, and how to delete it in a way that ensures data consistency.

Editing the definition of a component Splitting a component Deleting a component

Copyright DASSAULT SYSTEMES 2002

48

Editing the definition of a Component (1/2) For each type of component, there is an Edit Component function in its contextual menu. This function gives access to the definition panel of the component, enabling you to edit most of the parameters defined at creation time : you can for example change the component variant to select other dimensions.

Tab Parameters allows access to the Design Table containing the list of available dimensions Copyright DASSAULT SYSTEMES 2002

49

Editing the definition of a Component (2/2) When several instances of a given component have been created by multiinstantiation, editing the position of one instance (via fields Instance Origin or using the green arrows in the preview) applies to the selected instance only. When several instances of a given component have been created by multiinstantiation, changing the dimensions of one instance affects all the other instances too (if option Several Instances per reference in Tools/Options was active at creation). Only the vertical position of the selected instance has been modified

Selecting a new variant with different dimensions has been applied to all instances Copyright DASSAULT SYSTEMES 2002

50

Splitting a component For the types of components which are impacted by Core/Cavity separation (Sprue Bushing, Ejector Pin, …), a dedicated function Split Component is available in their contextual menu. This function works in the same way as the splitting of Core and Cavity plates.

Note that, for consistency reasons, it is not possible to split a component for which several instances have been created from the same reference. To do so, it is necessary that option Several Instances per reference for this component has been deactivated at creation time. Copyright DASSAULT SYSTEMES 2002

51

Deleting a Component For all components, there is a dedicated function Delete Component in their contextual menu. This function will perform a “smart” delete, removing not only the components, but also its associated holes in the various plates. It is mandatory to use it instead of the standard Delete function, which does not ensure such consistency. Several components can be deleted simultaneously, by multi-selecting them graphically or in the specification tree.

Advanced Mold Base : Creating Inserts You will learn how to define an Insert in the Mold.

Defining and positioning an Insert

Copyright DASSAULT SYSTEMES 2002

54

Advanced Mold Base : Defining and positioning an Insert (1/4) Defining Inserts : If necessary, you can create Inserts in your Mold Base, for example in the case of a multi-impression Mold. You can create in Core Plate and Cavity Plate the main inserts corresponding to your part, but you can also create additional inserts inside these main inserts, if the complexity of your part requires so.

Creating an Insert : You must first update the overlap values between Core and Cavity plates (= 80% by default), since contact between InjectionSide and EjectionSide of the Mold will happen via the inserts on each side, and no longer via Core and Cavity Plates. Select Mold Edition in contextual menu of the Mold Base

56

Advanced Mold Base : Defining and positioning an Insert (3/4) Creating an Insert : Define the position of the insert : You can pick any of the following elements in order to position the insert : • A planar face of the plate. The application switches to mode “Work on plane” : you can then use the grid to define the position of the insert. The behaviour of this mode can be controlled via Tools/Options/Mechanical Design/Sketcher • A 3D point • A 2D point (point in sketch, vertex) Pick a position on this face to have a preview of the Insert and adjust its position by using Instance Origin values and/or the green arrows and half-circle attached to the preview of the Insert

Copyright DASSAULT SYSTEMES 2002

57

Advanced Mold Base : Defining and positioning an Insert (4/4) Creating an Insert : Define the elements of the Mold to be drilled by this insert (typically the Core Plate for the main Core Insert, and the Cavity Plate for a main Cavity insert). Adjust the dimension of the insert using tab Parameters Split the Insert using function Split Component… in contextual menu

Copyright DASSAULT SYSTEMES 2002

59

Advanced Mold Base : Defining and positioning a Slider (1/4) The definition of a Slider mechanism is done by creating the following components : The Slider component itself The corresponding Retainers component The Screws components fixing the Retainers to the Mold Base The Angle Pin

As for Core and Cavity plates, it is necessary to have prepared beforehand the Split surface of the Slider component, for example by using application Core&Cavity Design (CCV).

The Molded Part contains an undercut area requiring the creation of a Slider mechanism Copyright DASSAULT SYSTEMES 2002

60

Advanced Mold Base : Defining and positioning a Slider (2/4) Creating a Slider : To create a Slider, use function Add Slider

Creating a Slider : Define the position of the Slider :

You can use the same positioning capabilities as for the other types of components, for example by first picking a planar face on the top of the Core Plate, then adjusting the position with the green sliders Copyright DASSAULT SYSTEMES 2002

61

Advanced Mold Base : Defining and positioning a Slider (3/4) Creating a Slider : Define the elements of the Mold to be drilled by the Slider (typically the Core Plate and the Cavity Plate) Adjust the dimension of the Slider using tab Parameters

Note that the Slider has been created with a location point and a location axis for further reuse when defining the Angle Pin

Note that the Slider has been placed in the tree structure at the same level as the main subassemblies of the Mold. This is necessary to ensure proper kinematic simulation.

Creating Injection Features You will become familiar with …

Creating a Gate Creating a Runner Creating a Coolant Channel

Copyright DASSAULT SYSTEMES 2002

69

Creating a Gate (1/2) There are 3 different types of gates : Direct : the Gate is located directly on the Molded Part Side (2 sub-types are available) : the Gate is located on the Parting Line Submarine (3 sub-types are available) : the Gate is located close to the Molded Part, joining it via a small nozzle.

The creation of a Gate is done in 2 steps : First step : define the Gate location (point)

Copyright DASSAULT SYSTEMES 2002

70

Creating a Gate (2/2) Second step : once the location point is created (materialized by a yellow square), you can define the characteristics of the Gate : 

Select the desired type, then subtype of the Gate, using Catalog icon in the Gate definition panel



Set the other parameters of the gate : Stamp and dimensions

At the end of these two steps, the Gate is materialized only by a yellow square in the 3D viewer. Its real shape will be created only once the Injection Runner has been created.

Copyright DASSAULT SYSTEMES 2002

71

Additional Information Gate creation The application creates in MoldedPart an Open Body called GateBody. It will contain the location (as Point name Gate.N) of all the gates created in this Part. You can modify their location by directly selecting them in the tree. You may create any number of gates. Note that the Gates are picked from catalogs : you can create your own catalogs with gates of one of the predefined types (direct, side, submarine), but with your own sketch.

Gate edition You can edit a Gate via option Gate Edition in its contextual menu.

Gate deletion At this stage, you can delete a Gate using standard function Delete, since it is only a point.

Copyright DASSAULT SYSTEMES 2002

72

Creating a Runner The creation of a Runner is done in two steps : Creating its layout using the Sketcher Defining its shape characteristics

Step 1 : Sketching the Runner layout The Gate point location must coincide with one extremity of the layout. There must be tangency continuity between all elements of the sketch. This is mandatory to ensure a correct projection of the sketch onto the support surface, operated by the application in the next creation step.

Step 2 : Creating the Runner

• Click icon Add Runner • Define the characteristics of the Runner In the case of the Oval section shape, you can define Core or Cavity side as stamp body. In the case of the Round shape, the stamp may be in Core, Cavity or both simultaneously. Note that when creating the Runner, the Gate is also created in the 3D viewer

Copyright DASSAULT SYSTEMES 2002

73

Creating a Coolant Channel (1/2) Coolant Channels can be created in all the plates of the Mold Base, e.g. in CavityPlate, CorePlate, CoreSupportPlate… They can be created using various types of support geometry : Two 3D points, which will be used as extremities of the Coolant Channel A 3D line : the application will then automatically use its extremity vertices as extremities of the Coolant Channel A Sketch made up of one or several segments

The support geometry must be created before entering function Add Coolant Channel, by using for example workbench Wireframe and Surface.

Note that support geometry must be created in component CoreCooling or CavityCooling, whatever plate the Coolant Channel will be drilled in. These components are automatically created by the application when the Mold Base is defined. Copyright DASSAULT SYSTEMES 2002

Creating a Coolant Channel (2/2) The creation of a Coolant Channel is done by activating function Add Coolant Channel : Pick first its support elements. If you have selected a sketch, a Coolant Channel will be created for each segment of the sketch.

Then define the parameters of the cooling pipe

Point1 is the start point and Point3 is the end point

D1 = inner diameter D2 = counterbore diameter L = counterbore depth A = V-bottom angle

The Cooling Channel is automatically located in a Body named CoolingBody

75

Additional Information… Coolant Channel creation If none of the elements you enter as extremities of the Coolant Channel belongs to the outer planes delimiting the faces of the plate, the system will automatically propose a pipe segment reaching one of these planes : you can use option Reverse to select the opposite pipe segment

If you use a predefined sketch, the system will prompt you, for each segment of the sketch, with the Reverse dialog box, in order to let you invert the pipe created on this segment if you wish

Coolant Channel edition You can edit a Coolant Channel via function Coolant Channel Edition… in its contextual menu

Managing User Components You will see how any Mold component is structured, and how to create and instantiate user-defined components

What is a User Component ? Structure of a Mold Component Creating a Catalog of User Components Instantiating a User Component

78

What is a User Component ? In addition to the predefined types of components (Leader Pin, CapScrew, Bushing, …) available, it is possible for you to create you own types of components (special plates, stamps, springs, …) You can also create your own designs for predefined types of components (e.g. a custom Leader Pin) to extend the libraries offered in the application The structure of a user-defined component must follow some rules to ensure it can be managed in application Mold Tooling Design in the same way as the standard components offered in the application

You can put your user components in your own catalogs and link your catalogs to those known by the application

Copyright DASSAULT SYSTEMES 2002

79

Structure of a Mold Component (1/2) A Mold Tooling Design component, either coming from provided standard catalogs (e.g. a Leader Pin), or defined by the user, must have the same basic structure. It is usually defined as a CATPart file, including potentially a list of variants (defined by a Design Table). It can be put in a dedicated catalog, but the file can also be selected directly in MTD functions. The CATPart must obey the following rules, illustrated below on a predefined type of component (Leader Pin) : The same name must be used for the CATPart (property) and for the user component referenced in the catalog (here LeaderPin_FSC). The shape of the part itself must be defined in PartBody (it may consist of Pads, Shafts, etc.) The negative volumes associated to the shape must be created in a Body named DrillHole. They must be defined using features with negative polarity (such as Hole, Pocket, …). These negative volumes will be automatically subtracted from the Mold Base plates when inserting the component (Remove features) The part must have a reference point used to place the component in the Mold. This point must be named Base and be located in a Body named BaseBody.

80

Structure of a Mold Component (2/2)

For some specific types of components (typically a screw), an additional Body named TapHole can be present to define the threaded holes to be drilled. Just like Body DrillHole, this Body will be used to perform a Remove operation, but only in the last plate impacted when inserting it. This is the plate specified as To when defining the first (Drill From) and the last (To) plate to be bored when inserting a component. A user component can be a CATProduct made up of several CATParts following the rules described above.

81

Creating a Catalog of User Components (1/3) Once you have created CATParts or CATProducts containing your user designs, following the structure described previously, you can create a new catalog to insert them :

1 Use workbench Catalog Editor to create a new catalog

2 Rename the default chapter to fit the kind of user components it will contain. You can add other chapters if you wish to add other kinds of user components.

Copyright DASSAULT SYSTEMES 2002

82

Creating a Catalog of User Components (2/3) Then you can reference your components in the new catalog : 3

Use function Add Family to define in the chapter a first family, i.e. a first set of this kind of user components. You can create other families in the chapter if you wish. If your user-component Part contains a Design Table corresponding to variants of your design, you must use instead function Add Part Family.

4 Use function Add Component to define the physical location of the CATPart or CATProduct containing your design. You can create other components in the family if you wish. 5 Use function Add Keyword to define the relevant parameters for your component

6 Then save the new catalog file, using the name you wish Copyright DASSAULT SYSTEMES 2002

83

Creating a Catalog of User Components (3/3) Then you must link you own catalog to the existing User Catalog provided with the application : 7 Open existing master User Component catalog : \intel_a\startup\components\MoldCatalog\UserComponent.catalog

8 Use function Add link to other catalog to make a reference from the master catalog to the chapter of the new user catalog

9 Define now a value for Keyword Supplier for the newly added chapter

10 Save the new version of UserComponent.catalog

84

Instantiating a User Component To instantiate a User Component in a Mold, use dedicated icon Add User Component : you have access to your own components in the same way as for predefined components (preview, positioning capabilities)

You also have access to some specific components delivered with application MTD :

Copyright DASSAULT SYSTEMES 2002

85

Additional Information… When your user component is of a predefined type known by the application, you can link your catalog to the one of this type, instead of linking it to UserComponent.catalog : For example, if you have created your own type of Leader Pin, you can link your catalog to LeaderPin.catalog, which is located in the same folder

It is not mandatory to put your user component in a catalog. When you want to instantiate it, it is possible to pick directly the CATPart file :

How to extract definition of Holes in Mold Base Plates For further machining purposes, you may need to collect, for some or all the plates of the Mold, the list of the holes with their characteristics : XY position, diameter, depth, etc. : This is done using macro \intel_a\code\command\CATMoldFindHolesInPlate.CATScript Before running it, make sure document Mold is the current document. The result is a .txt file (text) for each selected plate, located in folder C:\Temp (redefinable). You can reformat it as for example an .xls file (Excel) and insert it in a Drafting layout.

Current limitation : Coolant Channels holes are not taken into account.
