Abstract

PURPOSE:To increase the tight contact pressure in the periphery of cavities during mold registering and to obtain castings of less burrs by providing parts slightly higher than joint surfaces in the peripheries of the cavities of top and bottom parts. CONSTITUTION:Parts 12, 14 slightly higher than joint surfaces 11, 13 are formed of molding sand, etc. in the peripheries of the respective cavities 4, 8 of a top part 1, and a bottom part 5. If the top part 1 is placed on the bottom part 5, the surfaces 11, 13 contact tightly and the parts 12, 14 are forced into the molding sand 3, 7 respectively, whereby the tight contact pressure and sealing property are increased. Therefore, the overhanging of the molten metal from the peripheral parts where the cavities 4, 8 are registered is prevented and the casting of less burrs is obtained.
