Abstract
PURPOSE: To decrease the amount of after-treatment of recovered sand and recycle the molding and inexensively by interposing a cooling material between the molding sand which forms a green sand mold.
CONSTITUTION: A molding flask 2 is placed on a pattern plate 1, and molding sand 3 is charged therein to the extent that the plate 1 can be buried. A powder or granular cooling material 4 such as, for example, ice or dry ice, is charged onto the top surface of the molding sand 3 in a manner as to be laid. Further, molding sand 5 is charged onto this, until the inside of the molding flask 2 is made full. Thence, it is compressed to make a prescribed green side mold 6, into which vent holes 7 are properly pierced. A molding flask 9 built in with a green sand mold 8 made in the similar manner is mated with said molding flask 2, and a prescribed sprue 10 is made. Molten metal is poured into the thus formed cavity 11. The moisture in the surface layer of the rapidly heated cavity part 11 evaporates to steam and goes toward the outside but the movement is stopped by the cooling materials 4, 12. The dry area of the molding sand 5 is less required and the moisture controlling of the recovered sand is less requied by suitably selecting the amount of the cooling materials 4, 12.
