Abstract
A closing unit of a shaping machine includes a moveable clamping plate, a push rod connected to the moveable clamping plate and having an outside profile, a divided locking nut provided with an inside profile, and a closing force mechanism for acting on the moveable mold clamping plate with a closing force. The push rod is lockable in a closed position of the locking nut by the cooperation of the inside profile and the outside profile with the closing force mechanism. For displacement of the locking nut between an opened and the closed position, a rotary drive is provided for rotation of a shaft, and at least one toothed rack cooperates with the shaft by way of a tooth arrangement and is connected to the locking nut.
