Abstract: A die for use with a die casting machine comprised of a left hand die half, a right hand die half, in which the die halves close on a part line, an injection nozzle seat, an injection fluid inlet, a runner and a cavity, the invention comprising a left hand die half having a protrusion extending over the part line when the die halves are closed, the top of the protrusion forming the base of the injection fluid inlet when the die halves are closed, the bottom of the protrusion is spaced from the upper surface of the lower part of the right hand die half

Abstract: Apparatus and method for closing, connecting, clamping, unclamping, disconnecting and opening the die halves attached to a moving platen and fixed platen of a the die casting machine comprising clamping means, open-closing means, and connecting-disconnecting means, the clamping means comprising a clamping cylinder and a clamping piston, the open-close means comprising an open-close cylinder connected to the rear of the moving platen and an open-close piston connected to the interior center of clamping cylinder, the open-close means comprising an insertion or removal of an insertion between the clamping piston and the open-close cylinder.

Abstract: A die casting machine having a frame comprising two connecting rods, two side platens, a moving platen, connecting rod apertures in said moving platen, a moving platen drive and two dies, wherein one side platen is connected to the two connecting rods, the other side platen is connected to the opposite ends of the two connecting rods, the moving platen is guided by said two connecting rods for movement towards or away from respective side platens by said moving platen drive, one die mounted on one face of the moving platen and the other die mounted on the inside face of one side platen, all said platens being located in parallel planes at right angles to the centerline of the machine, the two connecting rods, the moving platen drive and the dies being in a common plane passing through the longitudinal centerline of the die casting machine.

Abstract: A die-casting machine is described which includes at least one cylinder/piston assembly. Each assembly has main, ejector and core pistons and cylinders. The main cylinder is stationary and holds a piston which reciprocates to bring the molds together for metal injection or apart for releasing a die casting. A portion of the interior of the main piston constitutes an ejector cylinder having an ejector piston and a portion of the interior of the ejector piston constitutes a core cylinder having a core piston. The present invention is more compact and less complex than conventional die-casting machines.

Abstract: A die casting metal hald mold comprising a front wall incorporating a die casting area, side walls extending rearwardly from the front wall, a backing member closing the base of said side walls, means to fasten the backing member to the bottom of said side walls, the front wall, side walls and backing member forming a high pressure heat exchange cavity, a valve for introducing fluid under pressure into said high pressure heat exchange cavity and a valve for releasing gas under pressure from said high pressure heat exchange cavity.

Abstract: A die casting system comprises a machine of the balanced, dual movement type wherein the part is cast and trimmed without any lateral movement. Both halves of the molds or dies are moved equal distances to and from the part plane. The machine incorporates a system of metal injection on the mold parting line with a runner-drain provision; provision for supporting the part at a plurality of points after the die opening; hydraulic fluid volumetric flow reduction; various nozzle configuration options and a heat transfer system for the dies. In addition, a part trimming machine is disclosed together with a cable transfer for moving the part from the casting machine to the trimming machine.
