Abstract
A device for demolding negatives in plastic injection, which is coupled to means for ejecting a plastic injection mold. A guide bushing can be attached to the die plate of the moveable part of the mold, inside which extends a counter-mold which molds the negative and is formed by a guide runner and a head that can be lowered to demold the negative. The guide bushing contains a projection which pushes against the side of the head as the counter-mold moves forward, so that the head is lowered sideways and the negative is released.
