A mold closing and locking device is disclosed, including a fixed mold carrier plate, a stationary end plate, a movable mold carrier plate displaceable between the fixed mold carrier plate and the stationary end plate on support shafts through the action of a piston-cylinder unit, an adjustable distance-determining member extending between the piston-cylinder unit and the movable mold carrier plate, a pressure plate carried on a swivel arm for movement into and out of engagement between said piston-cylinder unit and said distance determining member, with the swivel arm being attached to a pivot bearing mounted on one of the aforesaid support shafts, with the pressure plate having a limited displacement range against spring tension in a direction parallel to the movement of the movable mold carrier plate, and with the swivel arm being movable by means of a pressurized pivot drive supported on another of the support shafts. The aforesaid spring tension is provided by a spring supported at the end plate and connected to the swivel arm by means of a flexible tension member which acts proximate the pivot bearing. The pivot bearing is axially displaceable along its support shaft. The pressure plate is flat and rigidly attached to the free end of the swivel arm.
