Week 8 - Challenge 6 - Core & Cavity Design

DESIGN OF CORE AND CAVITY BLOCKS

Aim

The aim of the project is to create the core and cavity block and perform draft analysis on the switch bezel component.
Below is the tree structure for the creation of core and cavity block.

Tooling axis

For the creation of tooling axis we are going with the bisecting line method because when we look at in Y direction we are observing two lines which are at a certain angle and if we find the bisecting line in this direction we can see every part of the componenet.
After creating this line we are going in Xdirection to see any lines are at a certain angle and there is only one lin and we are going to create line at 6° normal to axis system which we created on the class-A surface.
After this we are going to find the bisecting line between the Y direction line and X direction line and in this way we will get our Tooling axis and if we view from this we can see the Draft angle on the component.

Class-A surface

The Class-A is provided by the OEM's and we will Convert this it into Closed Surface.

Class-B surface

The Class-B surface is Created from offsetting the Class-A surface to 2.5MM and we have to solve some patches by extrapolating and trimming it and then we apply fillets.

Class-C surface

This surface is Created from the Class-A with Sweep along with Draft direction at 3°.

Creating the Core and Cavity

For creating the core and Cavity We are taking the Class-A, Class-B and Class-c surfaces.
First we are trimming the Class-A and Class-C and Then Class-B and We will get the Closed Surface after this we are going to create a sketch on YZ plane and Extruding to a Certain length.

Cavity design

Parting surface

It seperates the the Class-A and Class-B surface and it is formed on B side surface.

Draft Analysis on the Switch Bezel

The draft analysis is performed to check Whether our component is clearing our desirable Design rules while manufacturing the component in the core and cavity block.
The Draft angle is between0°-3°.
We will check the draft angle along the Tool axis.
