Abstract

A two-shot injection molding assembly is provided where the tooling that creates the mold for the first material can be retracted and the tooling that creates the mold for the second material can be inserted. The first material tool blocks the mold area that is intended for the second material to be injected. After the first material is injected into the mold, the first material tool can be retracted and replaced with the second material tool. The second material tool creates a side for the mold that is used to form the second material injected into the mold, and a spring based wedge forms the other side of the mold. By having the first material tool retracted and replaced with the second material tool, the core plate does not have to be rotated.
