Abstract
An injection molding machine includes a stationary frame having a pair of spaced upright stationary plates which guide rods of a movable frame which includes, at opposite ends of the rods projecting beyond the stationary plates, a pair of movable plates. One of the stationary plates and the movable plate adjacent thereto respectively carry complementary parts of a split injection mold. A unit including a pressure plate fixed to the other stationary plate is arranged on the rods between the other of the stationary plates and the movable plate adjacent thereto. Cylinder and piston arrangement connects the unit and the movable plate adjacent thereto for moving the movable frame relative to the stationary frame and therewith the mold parts between open and closed positions. The unit includes a clamping device for clamping the unit in fixed position onto the rods a hydraulically operated arrangement cooperating with the pressure plate for preventing the mold parts, when in the closed position from opening under the pressure of the material injected thereinto.
