Week 8 - Challenge 6 - Core & Cavity Design

Core and Cavity Design for switch bezel

Aim :

To create the core and cavity blocks for the switch bezel we have already designed as the solid part.

Objective :

• Create the required Tooling axis by using the bisecting method.
• Perform the Draft analysis on the solid model.
• Create the parting line and parting surface.
• And create the core and cavity blocks for the switch bezel.

TOOLING AXIS

A surface is extracted from the base of the cavity and a point is created at the center of the surface. A axis system is created on the point.

A sketch is created and an intersection sketch is created on the surface

Two lines are created on the two inclined walls of the, using the bisection command in the line command a line is created

DRAFT ANALYSIS

Using free form analysis and the tooling, draft analysis is performed on the solid part

PARTING SURFACE

A parting line, in the industrial casting of molds, is the borderline in which draft angles change direction. That is, it is the dividing line that splits the core and cavity halves of a molded part. It is sometimes a starting point for the mold parting surface.

CORE CREATION

• The core design is started with extracting the parting surface that becomes the datum for the core and cavity. The parting surface in most of the cases is kept at the B class surface to avoid close and tight contact between the core and cavity.
• At first, the A-class surface is extrapolated with some length and later it is trimmed with a C surface

CAVITY CREATION

• The cavity is the part where the injector and filling of the molten plastic happens. The cavity block is prepared by first extruding the outer boundary along the tooling direction.
