Abstract
PURPOSE: To mold a shell mold at a low cost without forming smoke or irritating odor, by filling sand mixed with paste in a heated metal mold, by calcining the sand at the surface of the mold so as to be hardened, then by removing the unhardened sand.
CONSTITUTION: The first blow tank 27 of a molding machine 1 is filled with about 100 parts sand mixed with about 3 parts binder made of water-soluble paste, and about 4W6 parts water, and the second blow tank 31 with green sand. Metal molds 14, 19 are heated to 120W250°C temp. respectively by heaters 13, 18, then both the metal molds 14, 19 are connected to form a cavity, which is filled with the mixed sand contained in the first blow tank 27, hereby the paste is hardened by the heat of the metal molds 14, 19 to form a solid mold. In order to make a hollow mold, the metal molds 14, 19 are turned round, and the unhardened sand is blown off by blowing high pressure air from an air nozzle 39 into the cavity. When the green sand is filled into the hollow mold from the second blow tank 31 after the unhardened sand is blown off, a solid mold may be obtained.
