Week 8 - Challenge 6 - Core & Cavity Design

CORE & CAVITY DESIGN :-

Aim-

Create the Core and cavity blocks for the switch bezel designed

Draft Analysis-

Draft analysis is the most importent thing for a part design process. It says, how Core & Cavity part are going to be and what will be the position of parting line & parting surface.

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.

CORE & CAVITY-

Parting Surface-

Generally injection mold has two major components : the movable half and the fixed half, during the injection 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-

It is the line of separation between where two halves of a mold meet. In most parts, it is just a line that runs straight down the middle

Core-

A portion of the mold that goes inside a cavity to form the interior of a hollow part. To create the core part make a rectangle on the plane of Parting surface. Make sure that rectangle cover some extra area beyond the product surface. Extrude the rectangle along the perpendicular axis of parting surface. Then trim the extruded surface with parting surface profile and make that solid.

Cavity-

Cavity part havr to with Class B surface. Previously make rectangle have to extrude along Class B surface with same way and trim that with Class B surface. After closing the opposit side with 'fill' command, part have to make solid.
