Week 4 Challenge

1. Define tooling direction

The Tooling Direction is basically the direction that the mold pulls apart. 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 Dyeline or the Tooling Direction.

2. Create tooling direction for Class A with 10 deg draft

A 'parting line' is the line of separation on the plastic part where the two halves of the plastic injection mold meet. The line actually indicates the parting 'plane' that passes through the part.

The parting line is the junction of the movable mold (B plate) and the fixed mold (A plate). It is usually the largest shape of the plastic part. And it is designed for the removal of the plastic part and the condensate.

Types of PL

1. flat parting line (eg a)
2. Inclined parting Line (eg b)
3. Step parting Line (eg c)
4. Curved parting line (eg d)

Create B surface of the given lens in surface modeling (not in part), with a 4 mm thickness

Create a Parting Line for thickened lens
