  2. Pro/MOLDESIGN Technical Tutorial How Can I ... Understand Pro/MOLDESIGN’s Basic Elements? Establish a Consistent Design Process? Use Simple Shapes to Define Complex Shapes?

  3. Overview • What is Pro/MOLDESIGN? • Pro/MOLDESIGN Process • Defining Mold Components • Choosing a simple technique • Creating parting geometry • Organization of the features • Pro/MOLDESIGN Advantages

  4. What is Pro/MOLDESIGN? • Software Tool for Defining the Components of Plastic Injection Mold

  5. Pro/MOLDESIGN Workflow Ref Model Parting Geometry Mold Components Work Piece Model Work Flow

  6. 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

  7. Defining The Process - Step 1 Combine Reference Model and Work Piece Model

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

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

  10. 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

  11. Main Intermediate Solid What Is It? A Closed Set of SurfacesMold Volume Defines the Overall Size of the Mold Inserts Defines the Contours of the Part to be Molded

  12. Main Mold Volume Why Create It? Source of All IntersectionsSplits Consumable Geometry Geometry Visualization Interference Checking

  13. Product Demonstration Process Steps 1 & 2 Assemble Reference Model Assemble Work piece Model Create Main Volume

  14. 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)

  15. Parting Geometry Parting Surfaces Open Quilts Mold Volumes Closed Quilts

  16. How To Define The Parting Geometry? Surface Modeling Solid Modeling Traditional “Blanket” Surface “Swiss Cheese” Surface

  17. Swiss Cheese Parting Surface 1. Fill Rectangular Slots 4. Core Pin 2. Fill Back Cut Out 3. Core/Cavity Surface

  18. Fill Rectangular Slots Surface Patch?

  19. Offset Parting Surface Create Surface Copy Fill All Inner Loops Create Offset Surface From Copy Surface Copy Fill Loops Offset

  20. Product Demonstration Fill Rectangular Slots

  21. Fill Back Cut Out Parting Surface Options Copy Original Surface Before Cut Was Created Original Geometry Create Surface Patch Surface Patch?

  22. FreeForm Parting Surface

  23. Product Demonstration Fill Back Cut Out

  24. Core/Cavity Parting Surface Flat, Extrude, Extend, Blend, Merge?

  25. Variable Section Sweep Surface

  26. Product Demonstration Create Main Parting Surface

  27. Core Pin Surface Gather, Revolve, Extend, Trim Volume?

  28. Revolved Parting Surface

  29. Product Demonstration Create Core Pin Surface

  30. Defining The Process - Step 4 Intersect Main Volume with Parting Geometry One Volume Split As Required for Each Mold component Two Volume Split Final Split to Divide Core & Cavity

  31. The Geometry Calculator What Is Split? Calculation of Resulting Volumes When Main Volume is Intersected by the Parting Geometry How Many Volumes to Find? One Volume Split Two Volume Split What to Split From? Mold Volume Work Piece

  32. The Geometry Calculator One Volume Split Input Output

  33. The Geometry Calculator Two Volume Split Input Output

  34. Product Demonstration Split Core Pin with One Volume Split Split Core/Cavity with Two Volume Split

  35. Defining The Process - Step 5 Create Solid Models Extract Split Volumes

  36. Product Demonstration Create Solid Models

  37. Organization of the Model Reference Model Work Piece Main Volume Parting Geometry Split Volumes Extracted Mold Components

  38. 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

  39. Regeneration External References Parent/Child Relationships Design Flexibility Design Changes Concurrent Engineering Maintenance & Conditioning Process Advantages
