ABSTRACT:
To displace a moving mold mounting plate (3), a threaded spindle drive is inserted between the moving mold mounting plate (3) and a fixed mold mounting plate (16), whereby one end of each threaded spindle is mounted in the fixed mold mounting plate (16) and is configured as a piston (9) of a hydraulic piston and cylinder unit. The pistons are mounted in the fixed mold mounting plate (16) in hydraulic cylinders and an increased clamping force is created for the platen clamping mechanism by an appropriate impingement of the piston (9). In addition, the invention provides a detachable anti-rotation mechanism (23) for the threaded spindles (15). The invention thus allows an inclined position of the mold mounting plates (3, 16) to be corrected, by the targeted rotation of one or more threaded spindles.
