Abstract
A core lifter system is provided for a plastic injection mold, particularly for use in a mold in which an undercut is to be formed in the molded part. The system has a core blade and a support for the core blade, with the support being formed to be mounted for linear translation on an ejector plate. The system is configured for fixedly retaining the core blade on the blade support at a desired angle of inclination of the blade relative to the support. In one form of the invention, the blade is adjustable, and pinned in place. In another form of the invention, a separate, inclined blade support is provided for each different angle of inclination desired for the blade, and the blade and the support are pinned together.
