Week 8 - Challenge 5 - Core & Cavity Design

AIM:

To show the Parting line and Parting surface of Switch bezzel component and thereby design the core and cavity block of the same

PARTING LINE:

A 'parting line' is the line of separation on the plastic part where the two halves of the plastic injection mold meet. The line actually indicates the parting 'plane' that passes through the part.

PARTING SURFACE:

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

CORE BLOCK:

The core is usually the interior or noncosmetic side of the part. The core side also contains the ejection mechanism that pushes the completed part out of the mold. Cavity (A Side)

CAVITY BLOCK:

A tool with one impression is often called a single impression (cavity) mould. A mould with two or more cavities of the same parts is usually called a multiple impression (cavity) mould.

CORE AND CAVITY BLOCK:

The core & cavity are the shaped sections in either half of the mould tool which give the plastic product its final shape. The hot molten material is injected into the core & cavity and then sets hard into shape. The design of the core & cavity is essential in the correct formation of the product.
