Abstract

PURPOSE: To produce a mold for precision casting of high dimensional accuracy for volume production at low costs by mounting a pattern using a thermoplastic resin in a female mold, filling refractory material slurry in the cavity part thereof and allowing the same to set then making the pattern extinct.
CONSTITUTION: Melt 2 of a thermoplastic resin such as polyethylene is injected into a metal mold 3 to form a plastic pattern 4. This pattern 4 is joined with a plastic pattern 5 to make an assembled pattern A. The assembled pattern A is inserted and fixed into a female mold 10 and refractory material slurry 11 is filled in the cavity constituted by the mold 10 and the pattern A. This refractory material 11 is heated to set, thence the shell 11A of the refractory material having set, the plastic pattern A and the mold 10 are put in one piece into a heating furnace or the like to make the plastic pattern A extinct. Thereby, the mold for precision casting formed with the cavity 9 into which molten metal is to be poured is manufactured with good workability in a short time.
