ABSTRACT:
A carrier for the injecting unit of the injecting machine is adapted to be transferred to different operating positions for forming moldings having sprues in different arrangements. The frame is adapted to be driven by a control device, which has a screw drive and a displacement-measuring device and is adapted to be fixed in its operating positions. The control device has detachably been inserted into retaining openings of the injection molding machine by an axial installing movement in a direction which is transverse to the injection axis. As a result, the injection molding machine can be delivered by the manufacturer in different versions, inclusive of a more expensive version in which the transfer movement of the injecting unit to the various operating positions can be program-controlled, and a less expensive version, which does not permit of a program-control of the transfer movement. The machine can be converted from one version to the other with a minimum of work.
