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.

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.

An injection piston, which has a plunger tip, a plunger piston ring, and a cap and bolts, attaches to an injection rod for use in an injection sleeve of a cold chamber die casting machine. The plunger tip includes a lubricating chamber, lubricating and air conduits, lubricating and air nozzles, an annular scraper ring and scrap exhaust conduits; and has a diameter which is less than the inner diameter of the injection sleeve. The plunger piston ring has an outer diameter corresponding to the inner diameter of the injection sleeve; and is secured to the plunger tip by a cap and fasteners.

A die-casting machine for the production of miniature die-cast parts of the type having a parting line and a plurality of cores includes a frame member having a plurality of tie bars and a first movable platen on one side of a parting line and a second movable platen on the opposite side of the parting line. The movable platens are slidably received by the tie bars and a pair of lever arms are provided wherein a first lever arm supports the first movable platen and a second lever arm supports the second movable platen. The die block is arranged into two halves about its own parting line such that one half is mounted to the first movable platen and the other half is mounted to the second movable platen. The particular arrangement of lever arms enables the die block to be positioned relative to the remainder of machine such that an arrangement of six retractable cores can be utilized as part of the die-cast part wherein there are three coaxial pairs configured for movement along conventional X, Y and Z axes. The positioning of the die block relative to the remainder of the machine is such that the total of six cores can be machine introduced without interference.
