Patent

CA 2048218

In a mold having a pair mold halves for molding plastic parts, there is provided an internal core lifter that has one end attached to an ejector system of a mold and that has an opposite end used to mold and eject the plastic part. A universal internal cone lifter is provided that reduces the number of custom core lifter designs and inventories because it can be cut to the desired length and pivoted to the desired angle. The one end of the core lifter blade both pivots and translates because it is mounted by a curved dovetail connection on a universal coupling that translates along a support. A linear dovetail sliding connection on the universal coupling slidably mounts the universal coupling for translation along a mating dovetail surface on a support as the mold halves shift between open and closed positions.
