Abstract

PURPOSE:To improve the quality of a product and to reduce the production cost by fixing annular heat resistant impact members to the outside circumference of hole casting bosses which support cores and executing internal chill, then exposing the heat resistant impact members by cutting. CONSTITUTION:The cores 7, 8 which form the shapes of the product are supported by the hole casting bosses 9a, 9b and the annular heat resistant impact members 1 are pushed onto the bosses 9a, 9b. Projections 3 for positioning act to securely and exactly fix the members 1. The floating and positional deviating of the members 1 by pouring are prevented when a molten metal is poured into the space A of a casting mold 4. A parting line P and the product shape S are formed by the cutting, by which the product 10 is obtd. Since the product 10 is formed by exposing the heat resistant impact members 1 after embedding the same by casting, the crack and deformation of the product are prevented and the quality is improved. Since the members 1 are easily built into the casting, the production cost is reduced.
