Week 8 - Challenge 5 - Door Trim Lower

DOOR TRIM LOWER

Aim:

Create the Door trim lower component to the given Class-A surface.

Objectives:

Creation of Tooling axis with suitable draft angle.

Creation of B and C surfaces for creating a solid component. Perform Draft analysis on Class A surface and Solid model hence created.

Draft :

A draft angle is calculated as a degree measurement (or, less often, an inch or millimetre measurement) from the vertical axis of a mould, and it helps account for thermoplastic shrinkage, a practical reality of the injection moulding process for most materials.

Reduces the chance of damage to the part due to friction during the release. Reduces wear and tear and chances of damage to the mould.

Tooling axis :

It is defined as the direction in which the mould/core and cavity open. Selection of the direction of the tooling axis depends on the ease at which components can be easily ejected.

B Surface :

To creating the b surfsce to the given class A surface . Take the offset of the class a surface by the tooling axis direction . To creating the B surface by using blend and multi section surface .

C Surface :

creating the C surface combine the class a surface and creating the b surface . take both surface in close surface in part drowing . and take solid state of the component .

Finaly publication of the following part

• A surface
• Tooling Axis
• B surface
• C surface
