ABSTRACT:
An apparatus for locking a horizontal plasticizing cylinder to the carrying block of the injecting unit of an injection molding machine having two cylinder-locking sliders which are disposed on opposite sides of the axis of said cylinder and are radially movable by means of hydraulic cylinders. In a locking position, the sliders extend in diametrically opposite recesses of the plasticizing cylinder. A shaft for driving the feed screw of the plasticizing unit has a coupling section which is formed with a radial guide groove, in which a screw-locking slider is radially displaceably mounted, the screw-locking slider being non-rotatably connected to the shaft. A coupling bridge is secured to the upper one of the cylinder-locking sliders. When the feed screw is in a desired angular position said coupling bridge is coupled to the screw-locking slider so that one cylinder-locking slider and the screw-locking slider are simultaneously moved to their locking positions.
