Week 8 - Challenge 6 - Core & Cavity Design

Tooling Axis Direction:

It is defined as the direction in which the mould/core and cavity open. Selection of the direction of the tooling axis depends on the ease at which components can be easily ejected.By analysing the component the most easily ejectable direction is somewhere close to the Z direction,(might be inclined to it) so we have made a sketch on the YZ plane of Axis System) to create a bisecting line considering the 2 faces which might be difficult to be tooled.

Here I designed only core and Cavity of the product.

Parting Surface:

Generally injection mold has two major components : the movable half and the fixed half, during the injecction molding process, these two halves are pressed tightly from a sealed hollow to avoid the melt flow leakage and maintain certain holding pressure, the pressed surface are called parting surface , usually parting surface are the biggest projection outline of the part.

Parting Line:

A parting line is an inevitable part of injection molded products.It is the line of separationbetween where two halves of a mold meet.It manifests itself on injection molded parts as a line that runs the entire perimeter of the part.In most parts, it is just a line that runs straight down the middle.

CAVITY DESIGNA mold is a hollow form typically made from stainless steel that has plastic injected into it to manufacture a plastic part.

The plastic is inserted into the mold cavity, which is a hole in the mold shaped like the desired part.
