Automatic casting machine

Abstract

An automatic casting machine for automatically die casting and die trimming of zinc, aluminum, magnesium, lead or injection molding of parts and delivering the finished parts die trimmed free of flash and separated from the runners, gates and overflows into a finished parts receiver. The machine can be fabricated as a modification of a conventional die casting or injection molding machine, primarily by the addition of a centrally located indexing finger which becomes fastened to the sprew or bung upon casting or molding of the parts. On each opening and closing cycle of the mold the rotating indexing device rotates ninety degrees thereby rotating the spider from the casting or molding location to a series of additional stations which may include the sensing and cooling station to cool the casting, a punch and trim die station to deburr the casting and punch the finished part from the spider, and a spider ejection station, which in the case of a die casting machine may be disposed so as to automatically result in the return of the spiders to the pot.
