ABSTRACT:
A vertical die casting press includes a frame supporting a stationary lower horizontal platen which supports a base plate attached to a lower mold. An upper horizontal platen is supported for vertical movement between vertical columns by corner lift cylinders mounted on the lower platen, and the upper platen encloses hydraulic cylinders for actuating blades for releasably locking the upper platen to teeth on the vertical columns at a selected height. The upper platen carries a relatively movable intermediate platen which supports a base plate attached to an upper mold. After the upper platen is locked to the columns, a hydraulic load cell or cylinder within the upper platen clamps the intermediate platen and upper mold to the lower mold and lower platen. Molten die cast material is transferred through a horizontal ceramic cylinder from a ladle inlet to a vertical shot cylinder within the lower platen and lower mold, and a shot piston injects the material upwardly from the shot cylinder through runners and into cavities defined by the molds. The intermediate platen and lower platen enclose hydraulic cylinders for extending and retracting a set of rollers which engage tracks within the corresponding base plates to provide for quickly removing and replacing a set of upper and lower molds and corresponding base plates.
