Abstract

PURPOSE:To enable the molding at an even and high packing density even in the case of intricate molds by charging sand grainy fillers into the spacing and supplying compressed air from above while giving vibrations for the specified time thereby letting the same pass through the fillers. CONSTITUTION:A molding flask 11 is placed on the pattern plate 7 mounted to a table 4 and molding sand 16 is charged into the spacing formed by this. Thence, the table 4 and pattern plate 7 are horizontally vibrated by operating a vibration motor 10 to give horizontal vibrations to the molding sand 16, thereby letting the same move horizontally while being fluidized. Following to this, a hermetic cover 12 is put on top of the molding flask 11 and compressed air is supplied into the molding flask 11 through air feed path 13, small holes 15, etc., then this compressed air passes in the molding sand 16 to let the molding sand densely and firmly deposit on the surface of the pattern plate 7. After this, only the air is released to the atmosphere through an exhaust port 5 by way of the samll holes 9, 9' and recess 6.
