Abstract

The invention relates to a device in injection moulding machines, particularly for the manufacture of articles (6) of plastic with high accuracy and at high speed, such as compact discs, comprising a mould with two mutually reciprocable mould halves with a cavity therebetween and a gripping means (5) which is adpated to be introduced into the space between the mould halves for removing finished articles (6) therefrom. For providing a further reduction of the time for each injection operation the invention suggests that the gripping means is made disc-like with at least one through-hole (7) with a circumferential contour (8) corresponding to that of the article (6) to be produced and adapted to constitute in introduced position between the mould halves a third mould part forming the outer limitation of the cavity and by which the article produced is retained after moulding for being removed from the moulding zone.
