Abstract
PURPOSE: To produce a sand mold for casting of superior shape accuracy, in producing the mold for casting, by first making a frozen pattern, molding this pattern into molding sand contg. a binder, then melting the frozen pattern by heating in a vacuum box followed b drying.
CONSTITUTION: Jellylike frozen water is put into a lower mold 10 for pattern and an upper mold 11 for pattern is put thereon and is fixed by means of latches 13, after which these are put into a refrigerating chamber of ≤-20°C, whereby a frozen pattern 1 is made. Next, the frozen pattern 1 is put into a baglike fine-meshed net 21 disposed in a vacuum box 20; at the same time, a sprue bar 2 and a head bar 3 made by a freezing method are disposed. Molding sand 4 prepared by mixing a water-soluble binder such as starch powder into dry silica sand is cooled down to ≤-10°C and is filled between the fine-meshed net 21 and the frozen pattern 1. A cap 25 made of a resin film or the like is put on the surface and the vacuum chamber 22 between the vacuum box 2 and the fine-meshed net 21 is evacuated, after which the frozen patterns etc. 1, 2, 3 are thawed by an electric heating method, and the shell layer 5 of the sand mold 4 is hardened by the thus produced water and binder, whereby the sand mold for casting of superior shape and dimensional accuracy is molded.
