Abstract
A clamping unit for an injection molding machine includes a drive mechanism for moving a moving platen of the injection molding machine in at least one direction. The clamping unit has a clamping cylinder for movably receiving a clamping piston which defines a piston chamber in the clamping cylinder, and a compensating cylinder for movably receiving a compensating piston which defines a compensating chamber in the compensating cylinder. The piston chamber of the clamping cylinder and the compensating chamber of the compensating cylinder are fluidly connectable by a direct, controllable connection so that fluid can shuttle back and forth between the clamping and compensating chambers during opening and closing of the clamping unit.
