The extension includes clamping levers which are arranged in pairs to hold the mold boxes im clamped engagement. At least one auxiliary cylinder is arranged in generally parallel relationship with the main cylinder and is located in a laterally spaced arrangement relative thereto for operation on the opposite side of the clamped mold box. The auxiliary cylinder is operatively associated with the main cylinder to be simultaneously supplied with pressure medium from a common source and acts on the extension to provide support during separation of the mold members from the pattern device.
