Week 8 - Challenge 6 - Core & Cavity Design
CORE AND CAVITY DESIGN
AIM: To Create the Core and cavity blocks for the switch bezel component.
1. CREATING TOOLING AXIS -
The Tooling Direction is basically the direction that the mold pulls a part. The mold is built in two separate pieces, basically. You have a Cavity side and you have the Core side. The Core pulls apart from the Cavity and that's the Dye line or the Tooling Direction.

4. 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 separation between 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.
THE YELLOW LINW IS THE PARTING LINE
CORE DESIGN
- Core - A portion of the mold that goes inside a cavity to form the interior of a hollow part.
- Core-cavity - A term used to describe a mold created by mating A-side and B-side mold halves.
CAVITY DESIGN
- A 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.
