Abstract

PURPOSE: To prevent shrinkage and to improve the yield of casting by laminating granular mold forming materials and metals for metallic molds, and charging molten metal from the runner and ingate provided on the granuler mold forming material side.
CONSTITUTION: Both half split molds 3, 4 of a mold device 1 laminate respectively shell materials 3a, 4a and metals 3b, 4b for metallic molds in the thickness direction. Molds 5 for grinding balls are formed in the boundary part of the shell materials 3a, 4a and the metals 3b, 4b, with the half part located on the shell material side and the other half on the metal side. Both dies 3, 4 are assembled in such a way that the shell material 3a, 4a sides come to the inner side, and the surfaces of the materials 3a, 4a are a parting surface 2. The materials 3a, 4a form a runner 6 and an ingate 7 communicating with each mold 5. The molten metal flowed into the molds 5 is cooled from the metal 3b, 4b sides, and the materials 3a, 4a sides continuous to the ingate 7 solidify after this and cause directional solidification; therefore, the molten metal solidifies without causing shrinkage in each mold 5.
