ABSTRACT INJECTION MOLDING MACHINE AND STATIONARY MOLD CARRIER FOR USE WITH A CENTER GATE MOLD AND AN OFF-CENTER GATE MOLD By an injecting unit, which is horizontally shiftable at right angles to the injection axis, plastic material is adapted to be injected into injection mold sections which can selectively be fixed to a stationary mold carrier. The moldside ends of piston rods of the advance-retract cylinders of the injecting unit are contained in and adapted to be fixed to sleeves provided on a sleeve carrier, which is slidably mounted on the mold carrier. Between the sleeves, the sleeve carrier is formed with an opening for receiving the plasticizing cylinder of the injecting unit. The sleeve carrier substantially covers the cylinder-receiving opening of the mold carrier in those areas which are not occupied by the plasticizing cylinder at a time. In such an injection molding machine it is possible to provide injecting units in which the piston rods of the advance-retract cylinders lie in a horizontal plane.
