ABSTRACT:
An apparatus for removing injection molded articles from an opened injection mold of an injection molding machine. The apparatus has a low structural weight and provides exact control of the movements of a grasping member for grasping the injection molded articles. The apparatus has a guide bed and a carriage movably mounted on the guide bed. The guide bed is aligned parallel to the direction of operation of the closing unit of the injection mold. The carriage includes a cantilever which extends transversely of the guide bed. The cantilever carries a slide member longitudinally movable on the cantilever. An adjustable support member is mounted on the slide member. The grasping member is mounted at the lower end of the support member. The grasping member is adjustable relative to the support member about at least two joints extending perpendicularly to each other. In addition to the drive for the carriage and the drive for the support member, the drive for the support member is also mounted on the carriage above the guide bed. Accordingly, the weight of the drive for the support member does not rest on the cantilever, the slide member and the support member.
