Abstract
A mechanical press has a self-adjusting device for automatically setting the position of the mould in the correct position with respect to the stroke of the pressram. The device is located between a fixed platen and a mould carrier and comprises a cylinder having at one end a stiffly resilient plug which normally covers a valve port in the cylinder; a volume of liquid is located between a piston in the cylinder and the plug. If the mould is incorrectly set for the ram stroke, the pressure generated in the liquid so compresses the plug to expose the port for release of sufficient liquid to reposition the mould.
