Overview of mold Wizard

The Mold Wizard application assists you in designing plastic injection molds and other molds. By default, all models are associative to the original product model.

Benefits

The Mold Wizard application was developed and tested with continuous input from mold designers and manufacturers. This ensures that the application meets the needs and priorities of mold makers, and answers real-world design challenges. Mold Wizard has design tools and procedures to automate the difficult and complex tasks involved in mold design. The application saves you time throughout the design process and provides full 3D models to manufacturing. If you alter the product design, you lose very little time because changes to the product model are associative to the mold design elements. Parting is the process of creating a core and cavity based on a plastic part model. The parting process is an important part of the plastic mold design, especially for parts with complicated shapes. The Parting module automates this process by providing key tools. Mold bases and component libraries are included from a variety of catalogs. Custom components, including sliders and lifters, sub-inserts, and electrodes, are also provided in the Standard Parts module. The Standard Parts module allows you to associatively place components with fitted pockets. Mold Wizard provides a user-friendly way to manage different kinds of standard parts. You can use the standard parts in the library, and customize the standard parts libraries as required.

Prerequisites

To use Mold Wizard effectively, you should be familiar with mold design and common NX commands. In the Modeling application, you should be familiar with:

Feature modeling

Free form modeling

Sketching

Curves

Layers In the Assemblies application, you should understand and be able to:

Use the Assembly Navigator.

Change the display and work part.

Add or create a component.

Create and replace a reference set.

Create WAVE linked geometry.

Mold Wizard design process

To get the maximum benefit from Mold Wizard, you design process should follow planning and execution steps like the following: 1. Create or obtain a solid model. 2. Analyze the model for moldability. Use the validation tools described in preparing the

model. 3. Plan the design of the tooling. Decide on the parts to be included in the mold and number

and arrangement of cavities. Allow for slides, lifter, ejectors, cooling, and so on. 4. Initialize a Mold Wizard mold design project. When you initialize, you specify:

2

o The project name and folder location. o The naming rules for component parts. o The units of measure. o (Optional) The molded part material and shrinkage factor.

5. Define the mold coordinate system for each product in the mold: o The orientation of the part in the mold. o The principal parting plane.

6. If necessary, define the shrinkage factor. 7. Define a workpiece for each product. 8. If you have multiple cavities, plan the cavity layout in the mold base. 9. Design shut-off geometry. 10. Define the parting edges on the model and create parting surfaces. 11. Add a mold base. 12. Add hardware, ejectors, slides, lifters, sub-inserts, gates, runners, and cooling lines. 13. (Optional) Design electrodes. 14. Create pockets in mold plates and other bodies to accommodate the hardware and other

accessories you added. 15. Compose a bill of materials. 16. Create drawings.

Geometry quality

You should carefully inspect and correct the product model before you start a Mold Wizard project. You must have a good quality product model to produce a good quality mold design. Molded Part Validation — Shows you potential draft problems, undercuts, and wall thickness variations. Examine Geometry — Identifies several problems such as corrupt data, self intersection, gaps, overlaps, spikes or cuts, and tolerance issues. Heal Geometry — Improves the quality of some imported models.

Moldability

Some product models do not have correct draft (mold taper) or designs for efficient construction of mold shut-off areas. You should correct the product model to have exactly the geometry that you want in the finished cavity and core. If you begin with a moldable product, you can:

Simplify the parting process.

Eliminate a source of errors that you may encounter if you add draft to individual tooling solids.

Get ready-to-manufacture cavities and cores. Start the Mold Wizard application before you open any parts to assures that the proper assembly load options are set so that interpart geometry links and expressions function properly. You can start Mold Wizard from the NX No Part state from:

The Application toolbar.

The Start command button to the Standard toolbar.

On the Application toolbar, click Mold Wizard.

Patching process overview

If you have a product model with internal openings, you must design a shut off for each opening. There are two patch-up processes to design shut-offs:

Sheet patch-up

Solid patch-up

11

Sheet patch-up commands

You can use sheet patches to model the required shut-off surface. When you use sheet patch-up commands multiple copies of the sheets are created, one for the cavity trim sheet and another for the core trim sheet. The copies are identified and automatically recognized by the software.

You create parting surfaces for internal openings with the following commands:

Surface Patch

Edge Patch

Auto Hole Patch

Existing Surface

Enlarge Surface

Solid patch-up commands

You can use solid patches to fill voids that have multiple shut-off faces, such as an opening for a snap-latch feature. The solid patch-up command simplifies the product model by filling openings with the patch body. You can create and use solid patch-up bodies by the following process: 1. Use the Create Box, Trim Solid, or Replace Solid command to create a solid to fill the

open area. 2. (Optional) Use the Split Solid command or modelling commands such as Trim Body to

trim the patch-up body to the necessary shape. 3. (Optional) Use the modeling Subtract command to fit the patch-up body to the model by

subtracting the product model from the patch-box with the Retain Tool option. 4. Use the Solid Patch command to unite the patch-up body to the parting model. 5. In the cavity or core part, as necessary, unite or subtract the patch-up body to create the

desired mold surfaces.

Trim Region patch-up process

You can use the Trim Region Patch command to patch an opening with a patch sheet that must

have several faces. Typically, you create a patch body and then extract a set of faces to define

the desired patch-up sheet body.

1. Use solid modeling or solid patch-up commands to create a solid patch-up body to fill the open area.

2. Trim the patch-up body to fit the product shape. 3. Use the Trim Region command to extract the required faces for a patch-up sheet.

Parting methods overview

Parting is the process of dividing a model into regions formed by the two halves of a mold, and by moving pieces in the mold. The Parting Manager dialog box has a series of parting related commands, much like a toolbar. Parting elements

There are several Mold Wizard parting elements:

1. Cavity Block 2. Cavity Trim Sheet 3. Product Model 4. Core Trim Sheet 5. Core Block

17

Trim-based parting process Confirm product model readiness

Use the Design Regions command to confirm that the product model is:

Oriented and positioned to the mold draw-direction.

Moldable, with proper draft or mold taper for mold release.

Designed with shut-off features considered

Designed with reasonable parting lines

Use the Workpiece Wireframe display in the Parting Manager tree diagram to assure that the product is contained within the workpiece.

Mold Wizard parting terminology

Patch-up sheets

Patch-up sheets can be:

Surfaces within an interior boundary, such as a hole in the product model.

Surfaces to fill open loops, such as notches adjacent to the main parting surface.

It is usually most convenient to complete patch-before sheets you create parting sheets.

When you create patch-up sheets, you shut off internal openings with appropriate geometry to seal openings against the molded material (plastic or metal). These sheets are also called shut-off sheets. The Mold Wizard application has both solid and surface-based methods to shut off openings. You can also include NX free form surfaces as shut off or parting sheets.

18

Regions and parting lines

The Extract Regions and Parting Lines command collects faces that belong to each region and extracts a set of trim faces. The extracted regions, patch-up sheets, and parting sheets are used to create cavity and core trim sheets. The parting lines are the extracted edges that delimit the cavity and core regions. You can use the parting edges, sometimes in conjunction with guide lines, to define various types of parting surfaces.

Guide lines and transition points

You can divide the parting loop into segments, where each segment is used to define a parting surface. The segments are delimited by guide lines and transition points. The guide lines can be used to sweep or extrude the segment between them. You can select the transition points at the end of every guide line if you need to define a transition sheet that touches the parting loop at that point. In legacy versions of Mold Wizard sets of curves were explicitly identified as transition curves, and segments could be delimited by explicitly created transition points. The software recognizes these legacy objects; however, the commands to create them are no longer needed and have been removed.

Parting surfaces

Parting surfaces are sheet bodies created from the parting line segments.

Parting sheet bodies are bounded on one set of edges by the parting lines, and they must extend beyond the workpiece. The software calculates a list of possible surface types that can be defined by each string of parting curves between two guide lines, and presents a list of surface creation methods in a dialog box. The list can include creation methods such as:

Extrude

Sweep

Bounded plane

Enlarge

You can accept one of the proposed methods, or skip the segment and create a sheet body using modeling commands.

During project initialization, the Mold Wizard software copies one of several template assemblies. The

details of the parting process vary depending which structure you use; however, the overall parting

process is the same.

Parting related part files

The *_prod or product subassembly part contains all of the geometry you need to create cavity and core models. Family molds have a separate product subassembly for each family member. Original product — You can make the product model read-only to protect it from accidental changes. The product model file is placed as a child component of :

The *_prod subassembly if it contains a part with the attribute MW_PARTING_SET, for example the Mold.V1 configuration template.

The *_parting-set subassembly if no part has the MW_PARTING_SET, for example the Original configuration template.

Molding — The molding part file, *_molding, contains a geometry-linked copy of the original product model. The geometry link exists in the template assembly and is automatically updated when you initialize a project.

In the molding part, you can add molding features such as tapers, split faces, and blends to make the product moldable. The advantages of adding molding features in molding part are:

19

The molding part is before the shrink (scale feature) part in the hierarchy. Axis-symmetric or general scale, if you use them, are reflected properly in your corrective features.

When you swap the product for a newer version (Parting → Swap Product Model) full association of your corrective features is maintained. This is true even if the original product is translated from another CAD system.

Shrink — The *_shrink part file contains a geometry-linked copy of the body in the molding part file. The geometry link exists in the template assembly and is automatically updated when you initialize a project. The linked body has a scale feature with a default value of 1.0. You can update the scale feature by:

Specifying a material when you initialize the project.

Using the Shrinkage command any time after initialization.

Parting — As you define a parting, the *_parting part holds the geometry necessary to trim a workpiece into cavity and core halves. Although the parting definition process is the same, the underlying modeling methods and the features in the part vary between the Mold.V1 and Original templates. The template parting parts in the Mold.V1 and Original configurations contain:

A workpiece body that becomes the parent of the trimmed cavity and core bodies.

The template parting part in the Mold.V1 configuration also contains:

A linked datum coordinate system that is used to support robust mold coordinate system updates.

The template parting part in the Original configuration also contains:

Seed geometry that is used the create parent bodies for trim sheets and solids in the cavity and core parts.

Cavity and core parts — The *_cavity and *_core parts have similar features. Each part contains:

A solid body linked to the defined workpiece.

A sheet body with which a solid body is trimmed to form the cavity or core insert body.

A trim feature that is suppressed in the template parts and unsuppressed when you define the cavity or core.

Parting Manager overview

The Parting Manager dialog box is a combination of a toolbar and a tree diagram.

Parting commands are organized into sequential steps:

Identify cavity and core faces.

Create cavity and core trim sheets and parting lines.
