Week 10 - Challenge 3 - Door Trim Lower with Engineering Features

AIM: Create the Door Trim Lower Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the draft angle requirements and performing the draft analysis on the model at the end.

Design the Heat Stakes and the locators considering the design rules.

Class A surface:

This is the styling surface that provides the aesthetic features of a component. A designer starts the design of component by given class A surface.

CREATION OF TOOLING AXIS:

Tooling direction has to be the direction in which most of the features can be easily cleared. To create the tooling axis first we have to check the best suitable direction for tooling by using the compass. the y direction is suitable for creating the tolling axis because in the y direction most of the surfaces are clearing while performing draft analysis. Generally tooling axis is created using bisecting line method but here A line normal to the surface is created in the y direction and considered the tooling axis.

In injection molding, the Class A surface is first analyzed to determine the axis or tooling direction that separates the molds. Tooling direction is critical for plastic product design because it determines mold direction.
