Pro/MOLDESIGN Process
1. Combine Reference Model and Work PieceAssemble Components Into Mold Model
2. Create Intermediate SolidCreate Trimmed Mold Volume
3. Create Parting GeometryCreate Parting Surfaces and Volumes
4. Intersect Intermediate Solid with Parting GeometryCreate One Volume Splits for Components and a Two Volume Split for Core & Cavity
5. Create Solid ModelsExtract Split Volumes

Defining The Process - Step 1
• Combine Reference Model and Work Piece Model
![Page 8: Pro/MOLDESIGN Technical Tutorial](https://reader035.vdocuments.mx/reader035/viewer/2022062500/56814ff2550346895dbdbd20/html5/thumbnails/8.jpg)

Reference Model
• Parametric Link to Design Model– Merge by
Reference– Manufacturing
Instance for:• Shrinkage• Draft, ect.

• Defines Overall Size of Mold Inserts• Reference Only
– No Geometry Is Altered• Geometry
– Simple Block– Detailed Unit
Workpiece Model

®®
Defining The Process - Step 2
• Create Main Intermediate SolidMold Volume
– Gather Mold Volume Using Srf&Bnd– Trim Reference Model from Volume
Workpiece Gathered Volume Trimmed Volume

Main Intermediate Solid
• What Is It?– A Closed Set of Surfaces
Mold Volume
• Defines the Overall Size of the Mold Inserts
• Defines the Contours of the Part to be Molded

®®
Main Mold Volume
• Why Create It?– Source of All Intersections
Splits
– Consumable Geometry• Geometry Visualization• Interference Checking

®®
Defining The Process - Step 3
• Create Parting GeometryParting Surfaces & Mold Volumes
– Open and Closed Surfaces• Intersect the Main Volume To Define Individual
Mold Component(s)– Consists of:
• Geometry for Individual Components• Geometry for Main Parting Line (core/cavity)

Process Advantages
• Creating Simple Shapes and Having Pro/MOLDESIGN Calculate the Complex Shapes
• Minimize Complex Surface Creation– Do not need to fill “gaps” where core pins or
inserts will be utilized• Visualization
