Week 8 - Challenge 2 - Switch Bezel Design

Challenge 2 - Switch Bezel Design

Aim

Create the Switch Bezel Plastic component through the given Class - A surface

Objective

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 a 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.

Design Consideration

1. Class - A surface should be aesthetically smooth and good.

2. Class - B surface should have all the supporting features like ribs.

3. Parting line should coincide with the B surface since flashing couldn't affect the aesthetic of Class - A.

4. Class - C surface should also pass the draft analysis.

CLASS A

Creating tooling axis:

• The ejection from the mold after manufacturing the interior trim must have the nominal 3-degree draft angle.

• Hence the tooling directions created by considering the above factor and bisecting method is used.

• The base surface of the class-A was extracted to create a reference point on the surface using the point, create a line in the z-direction and an axis system was inserted to the point then using projection intersection along the yz plane is created and the two inclined lines were drawn inside the positioned sketch.

• then bisecting lines with the two inclined lines were created.

DRAFT ANALYSIS

CREATION OF CLASS B

CREATION OF CLASS C

The edges of the Class-A surface are extracted using the multiple extracts and then converted into smooth curvature to avoid the patches.

Sweep operation is performed (with draft direction) selecting the smooth curves as the guide curve and tooling axis as the direction and draft angle as 3degree
