The invention relates to a device for demoulding negatives in plastic injection, which is coupled to means for ejecting a plastic injection mould and includes a guide bushing that can be attached to the die plate of the movable part of the mould, inside which extends a counter-mould which moulds the negative and is formed by a guide runner and a head that can be lowered to demould the negative. The guide bushing contains a projection which pushes against the side of the head as the counter-mould moves forward, so that the head is lowered sideways and the negative is released.
