Injection-moulding system with exchangeable plasticating unit

摘要

To minimize the change-over times of an injection-moulding system with exchangeable plasticating unit, there is provided a prewarming station, in which the plasticating units are connected to a supply connection and can be preheated under operating conditions. For quick and preferably automatic fastening and releasing of the plasticating units in the injection station and in the prewarming station respectively there are in each case provided a hollow-shaped receptacle and clamping devices with wedges, which interact axially and radially with corresponding wedge surfaces on the plasticating unit.
