Abstract: A die casting machine has a frame with a base plate pivotally mounted thereon and supporting a furnace pot. A die assembly is mounted on the front face of the base plate and a double locking toggle arrangement is used to open and close the dies. The gooseneck assembly is mounted for linear movement to actuate the nozzle onto the die parting line.

Abstract: The specification discloses a die casting machine of the type adapted to form an article with an internal threaded portion. The threaded portion is formed by means of a threading device which is retractable. The threading device is rotatably and retractably operated by a pinion which in turn is rotated by a cog wheel. The die casting machine may contain a plurality of molding cavities, each being provided with the threading device. The cog wheels may be driven by a common rack which is hydraulically operated. Since the threading device of this invention is retractable, it is feasible to repeat a casting cycle without replacing the mold. Thus, it is much faster to fabricate such articles with the present machine than conventional die casting threading apparatus. Because no part is replaced or removed from the die casting machine in the present invention, it is possible to minimize possible dimensional variation among the articles fabricated.
