Abstract
A foundry molding machine for producing mold halves in mold forming assemblies which include a pattern device and mold boxes and operates to separate the formed mold halves from the pattern device through operation of a generally vertically extending main cylinder which includes a piston rod having an extension thereon. The extension includes clamping levers which are arranged in pairs to hold the mold boxes in 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.
