CSWP Mold Design 2 — Questions and Answers
Question 1: In SOLIDWORKS Draft Analysis, what does a GREEN color on a face typically indicate?
- The face has negative draft and will not release from the mold
- The face has positive draft and is properly angled for mold release (Correct answer)
- The face is a straddle face crossing the parting line
- The face has zero draft and is perfectly vertical
Correct answer: The face has positive draft and is properly angled for mold release
Green faces in Draft Analysis indicate positive draft, meaning the face is angled in the correct direction relative to the pull direction for proper mold release.
Question 2: What is the purpose of side cores (slides) in injection mold design?
- To add additional ejector pins in deep core pockets
- To form undercut features that cannot be released in the primary pull direction (Correct answer)
- To increase the cavity volume for thick-walled sections
- To cool the parting line region more effectively
Correct answer: To form undercut features that cannot be released in the primary pull direction
Side cores (slides) move laterally as the mold opens to form undercut features — such as side holes or recesses — that would otherwise prevent part ejection in the main pull direction.
Question 3: Which SOLIDWORKS Mold Tools feature generates the surface that divides the mold workpiece into core and cavity halves?
- Parting Line
- Ruled Surface
- Parting Surface (Correct answer)
- Lofted Surface
Correct answer: Parting Surface
The Parting Surface extends outward from the parting line edges to form the dividing surface used by the Tooling Split to separate the mold block into core and cavity bodies.
Question 4: What does Undercut Detection in SOLIDWORKS identify on a molded part?
- Regions where two assembly components interfere
- Areas of geometry that cannot be released in the specified pull direction (Correct answer)
- Faces that have an insufficient draft angle
- Wall sections that are below the minimum thickness for the material
Correct answer: Areas of geometry that cannot be released in the specified pull direction
Undercut Detection highlights geometry that would be mechanically trapped by the mold when opening in the pull direction, indicating where side cores or special tooling is needed.
Question 5: When applying the Scale feature for mold shrinkage, what does the origin point control?
- The direction in which the part is scaled
- The center point from which the part geometry expands uniformly (Correct answer)
- The material shrinkage percentage used in calculations
- The location of the parting line after scaling
Correct answer: The center point from which the part geometry expands uniformly
The scale origin determines the fixed reference point from which the part geometry grows uniformly to compensate for material shrinkage, typically set to the part origin.
Question 6: What does a RED color on a face in SOLIDWORKS Draft Analysis indicate?
- The face has positive draft and is ready for mold release
- The face has negative draft and will resist mold release (Correct answer)
- The face is a neutral (parting) face with zero draft
- The face contains an undercut requiring a side core
Correct answer: The face has negative draft and will resist mold release
Red faces in Draft Analysis indicate negative draft — the face is angled in the wrong direction relative to the pull direction and will prevent the part from releasing cleanly.
Question 7: After performing a Tooling Split in SOLIDWORKS, the resulting core and cavity bodies are stored in which type of file?
- Separate individual part files (.sldprt)
- A multi-body part file (.sldprt) with multiple solid bodies (Correct answer)
- An assembly file (.sldasm) containing both bodies
- A drawing file (.slddrw) with section views
Correct answer: A multi-body part file (.sldprt) with multiple solid bodies
The Tooling Split creates multiple solid bodies within a single SOLIDWORKS part file; the bodies can later be saved as separate files using the 'Save Bodies' feature.
