Week 8 - Challenge 6 - Core & Cavity Design

Object :- Create the Core and cavity blocks for the switch bezel designed. And performing draft analysis on the switch bezel component.

Introduction :- This project is done on CATIA software. This software is different from other. It is easy to designing for surface modelling. Its have more accuracy than other. This software is amazing for plastic molding.

Switch Bezel Part :- Switch Bezel is the part in which door window switch is situated. This part is made by plastic molding process.

Draft Analysis of this :-

Core and Cavity-

Core is an extended or male portion of the mould which creates the internal plastic part surface whereas Cavity is a depression or female portion of the mould which creates the external plastic part surface.

Core- Core which I have designed.

Cavity- Cavity which I have designed.

Assembly-

Parting Surface :-

A parting surface is a surface that separates the mold block into two parts – the core and the cavity.

In other word these two parts are pressed tightly and formed a sealed hollow to avoid the melt flow leakage and maintain certain holding pressure, the pressed surface are called parting surface.

Or you can say parting surface area is the area where core and cavity meets. It's called Parting Surface.

Parting Surface is attached with class B surface. Parting surface design directly affects the quality, ease of construction and operation of the injection mold, the mold design is one of the key factors to success. In the below figure blue area is the parting surface.

Parting Line :-

Parting line is the line where parting surface and parts meet. In other word it is the junction between your core half and the cavity half on the parting surface. In the below figure yellow dotted line is the Parting Line.

Conclusion :- In this challenge I have learned that how to create Core and Cavity. And How to create Parting Surface and Parting Line, and what is the purpose of this.
