Tappet body casting die

The invention provides a tappet body casting die which is a one-piece resin sand mold. Four to eight tappet body one-piece cavities are uniformly distributed in the circumferential direction of the one-piece resin sand mold. A sprue cup is arranged at the top of the one-piece resin sand mold, and directly communicates with the one-piece resin sand mold. Exhaust holes are formed in the top of the one-piece resin sand mold at the periphery of the sprue cup. The quantity of the exhaust holes correspond to that of the tappet body one-piece cavities. The exhaust holes communicate with the upper ends of the tappet body one-piece cavities. The tappet body casting die has the advantages that the thinking is innovative; an open casting system is arranged, and an upper box and a lower box are not needed; in casting, the lower bottom surface is placed on a chilling block; a box lifting prevention effect is achieved by virtue of the self weight of molten iron in the sprue cup; in casting, press iron for box pressing is o
