Abstract

PURPOSE:To prevent the generation of shrinkage cavities by disposing a consumable pattern only to the thick part of a casting mold or providing the consumable pattern which is formed to the mass per unit area of the consumable pattern to be formed on the thin part smaller than the mass per unit area of the thick part. CONSTITUTION:The thick part 3 and the thin part 3' are provided to the joint surfaces of upper and lower molds 1, 2 and the consumable partial pattern 3a consisting of foamed polystyrene is provided only on the thick part 3 of the cavity. A molten metal poured into the mold from a sprue 4 burns and evaporates the consumable pattern 3a. The molten metal which is simultaneously deprived of heat as well is poured into the cavity and is solidified. The molten metal in a runner 5 exhibits a feeding effect at this time. The generation of the shrinkage cavities in the packing casting is thereby prevented. The consumable partial pattern is preferably formed thinner than a product shape 22 in the thin part and is formed to the shape of the product in the thick part 21.
