1. ® ® Pro/MOLDESIGN Technical Tutorial Scott Morris Product Manager Tooling Applications Pradeep Tilak Quality Assurance Engineer Tooling Applications

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 Work Piece Model Ref Model Parting Geometry Mold Components Work Flow

6. ® ® Pro/MOLDESIGN Process 1. Combine Reference Model and Work Piece Assemble Components Into Mold Model 2. Create Intermediate Solid Create Trimmed Mold Volume 3. Create Parting Geometry Create Parting Surfaces and Volumes 4. Intersect Intermediate Solid with Parting Geometry Create One Volume Splits for Components and a Two Volume Split for Core & Cavity 5. Create Solid Models Extract 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 Solid Mold Volume –Gather Mold Volume Using Srf&Bnd –Trim Reference Model from Volume WorkpieceGathered VolumeTrimmed Volume

11. ® ® 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

12. ® ® Main Mold Volume Why Create It? –Source of All Intersections Splits –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 Geometry Parting 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. ® ® Traditional “Blanket” Surface “Swiss Cheese” Surface How To Define The Parting Geometry? Surface ModelingSolid Modeling

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

18. ® ® Fill Rectangular Slots Surface Patch?

19. ® ® Offset Parting Surface Create Surface Copy –Fill All Inner Loops Create Offset Surface From Copy Surface CopyFill LoopsOffset

20. ® ® Product Demonstration Fill Rectangular Slots

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

33. ® ® The Geometry Calculator Two Volume Split Output Input

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
