Core & Cavity Design

Aim - Create the Core and cavity blocks for the switch bezel designed

core and cavity -

The core & cavity design of the plastic injection mould tool is what gives the final product its shape, but there are several other functions of the tool that are crucial for the correct formation of the end product.

The tool places a large role in the correct cooling down rate of the moulded plastic part. If a plastic material sets at the wrong speed, distortion and stress may occur. The material of the tool should be chosen to keep cooling down rate in mind. Some plastic materials may need to be moulded in a water cooled tool.

Procedure -

• image showing the class a anmd class c surface

• first we have to take extroplate class A surface then we have to trim it with class c surface as shown in the image .

• now we have to create a rectangular sketch there by they should be normal to each other

• using the same sketch we need extrude it and trimm it with class b

• since the mould have formed then we need to convert them into solids by going to the part body and using the close body option.
