Week 8 - Challenge 5 - Core & Cavity Design
Aim: To creat core and cavity block for the switch bezel mould.
Objective:
The core and cavity creation after analysing the surface A and surface C, create the partition line and surface where the core and cavity comes together.
Parting line and surface:
The parting surface is the intermediate surface between the core and the cavity part of the mould. This surface splits the mould into two halves. While the parting line traces out the borderline of the parting surface, the line splitting the core and cavity of the mould.
Draft Analysis:
From the draft analysis carried out, the tooling direction clears out the part.

Core and Cavity Design:
Parting Surface:
Initially, the boundary of the class A surface is extracted and the class A is extrpolated to trim with the class C surface.


This extra surface area outside the component is where the core and cavity seperated.
Core Block:
Rectangular sketch is made on extrapolated surface i.e. the parting surface.

This sketch is then extruded along the normal component and then trimmed with component to give out the projection feature.


The same procedure carried out for cavity part to give depression feature to it.

Then the intersection between the component and the surface B is taken out as this is where the parting surface is created.

Spliting the parting surface with this line will give the actual parting surface removing the component.

Then core and cavity blocks are given closed body command to make a solid component.

Conclusion:
Thus the core & cavity design is completed using generative shape design and part design workbench.
