Week 8 - Challenge 6 - Core & Cavity Design

Aim

To create the Core and Cavity blocks for the switch bezel plastic component designed.

Tooling Axis

In Molding, machine arrangement is given to open the mold along a direction which is known as Tooling Direction. In other words. The mold is built from two separate halves (Core and Cavity) and tooling direction basically defines the direction of mold or core pulls apart.
The tooling axis is created by Bisecting method.
Bisecting method : This technique is used to generate tooling axis. First, the direction of molding must be decided. Next, a dummy tooling axis is created for the purpose of reference. With this approach, we pick the surfaces that could cause issues and consider intersections in the x and y directions. Using these curves, we create two lines, from which we create a bisecting line in both the x and y directions. Tooling axis clearing x direction and tooling axis clearing y direction are the terms used to describe how the clearing is carried out.

Switch Bezel Plastic Component

Draft Analysis

The Draft Analysis command enables you to detect if the part you drafted will be easily removed. This type of analysis is performed based on color ranges identifying zones on the analysed element where the deviation from the draft direction at any point, corresponds to specified values.
Most parts or applications require minimum of 1/2 to 1 degree, however 3 degrees is widely accepted as the norm.
Draft analysis on final plastic component.

Parting Surface

Generally, injection mold has two major comonents: the movable halve and the fixed halve, during injection molding process, these two halves ar pressed tightly and form 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 surface design directly affects the product quality, ease of construction and operation of the injection mold, the mold design is one of the key factors to sucess.

Parting Line

Creation of Core Block

Core is the side of the tool where the plastic part is injected from; also known as the bottom half of the tool. The upper half of the mold is called core.

Creation of Cavity Block

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.

Conclusion

Thus the Core and Cavity blocks for the switch bezel plastic component is created.
