DESIGN AND DRAFT ANALYSIS OF SWITCH BEZEL

AIM:

The objective of the project is to design the switch bezel and to do a draft analysis for it by creating the required tooling direction with the help of Bisecting method.

Introduction:

The control panel bezel is the frame part of the window switch that holds its switch covers and buttons into place. Moulding is the method used to manufacture the plastic trims of an automotive by most OEM’s, hence by considering the manufacturing consideration the switch bezel is designed.

• Class – A surface should be aesthetically smooth and good.
• Class – B surface should have all the supporting features like ribs.
• Parting Line should coincide with the B surface since flashing couldn’t affect the aesthetic of Class – A.
  • Class – C surface should also pass the draft analysis.

Procedure:

Given Class A surface:

Creating Tooling Axis:

Tooling axis for Draft Analysis and C surface.

Draft analysis for A surface.

Creating B surface:

Creating C Surface: for creating C surface it not possible to perform Sweep due to many points so, need to use smmoth curve comond to get C surface.
