An injection molding machine assembly for use with an operating injection machine comprises a tool unit mounting support adjacent the injection machine, a plasticizer and ejection unit mounting support adjacent the mounting support for the tool unit. Each support has associated with it a coupling element for connecting the associated tool unit or plasticizer and ejector into an operative condition or into a standby heating condition, for example. In addition there is a magazine which has at least one additional support for either or both of a tool unit and an ejection and plasticizing unit. An ejector and plasticizer is advantageously provided on a mounting support as well as in a magazine support. In addition a tool unit is provided on the mounting support or in the magazine support. A transport unit is associated with the magazine and tool in the ejector mountings and is movable between them for transporting one or both of a plasticizer and ejector or a tool unit to the mounting support in the operating position as desired. The construction advantageously includes a control for automatically effecting the transportation and the coupling of the units in the operating position adjacent the injection molding machine.

Injection molding machine assembly having means for selectively changing

A working machine, particularly an injection-molding machine includes two separable mold parts which are closed together in at least one direction and an injection device for the mold which produce inertial forces and which are mounted for movement on a fixed support in at least one direction. The device includes an actuator also mounted on the support having a movable actuator part connected to the machine part which is displaceable in the direction of the inertial force.
