ABSTRACT:
An in-mold degating device that includes a base having mounting ears for removable attachment to a mold system. The base is removably attached to the die half such that the uppermost surface of the base is flush with the surface of the die half. The insert further includes a body fixed to the base including a pair of opposed surfaces that define predetermined relief angles relative to the base. The body further includes a gate flow passage having an inlet within one of the opposed surfaces and an outlet within the other of the opposed surfaces. The gate flow passage tapers inwardly from the inlet to the outlet. The outlet includes an edge surface that forms an acute angle relative to the gate flow passage. The edge surface defines a shearing edge point that separates the finished molded part from cooled excess material.
