Week 9 - Project 1 - Door Trim Lower with Engineering Features
DESIGN AND DRAFT ANALYSIS OF DOOR TRIM LOWER WITH HEAT STAKES AND LOCATORS
Class A surface
Draft analysis
Draft analysis is done to check plastic parts moldability for the ease of removal from the injection mold. A tooling direction is required to create the draft in the component, which acts as the drafting direction.
Tooling direction
- Considering the ejection from the cavity of the mould after manufacturing the interior trim must have the nominal 3-degree draft angle (minimum).
- Hence the tooling direction is created by considering the above factor and bisecting method is used.
- The base surface of the class-A was extracted and a point at the center is created and an axis system was inserted to the point.
- Then intersection of the Class A & xy plane is created and the two inclined lines were drawn. Then bisector line of the two inclined lines is created.
Tooling axis
Procedure for Draft Analysis
- The draft analysis tool is selected.
- Then by enabling compass the axis system is aligned in line with the tooling axis, to define the draft direction.
- Now the surface or part which should be subjected to draft analysis is selected.
- Lock Direction is applied that fixes the compass and then the mode dialog box is formed by snapping at any point on the part
- The Color Codes are classified and Draft Angles are applied
- Then the Running point analysis is used to hover around the part to analyze the permissible draft angles and the analysis is saved.
- This gives the result of the surfaces which have positive draft in green code.

CONCLUSION
The Class B & Class C surfaces and the Tooling Direction have been created and Published and the Door Trim part body is developed with the B side Engineering features ( Heat stakes & 4 way locators. Both the Class A surface and the Solid body have been successfully passed the Draft Analysis.
