Abstract

PURPOSE:To easily manufacture a casting core of thin thickness by setting a piece consisting of a dissipating material having a hollow part, to a core forming mold, packing said hollow part and the inside of the mold with core sand, and hardening them integratedly. CONSTITUTION:A plate-like piece 20 is formed by a material which dissipates at the time of casting of foaming polystylene, etc., and in this center, a hollow part 21 for passing through to the right and left is provided, and also, its side face 22 is formed to a desired curved surface shape. Said piece 20 is set to a core forming mold consisting of the lower mold 1 and the upper mold 2 provided with circular grooves 3-5, etc. Subsequently, core sand is blown in from packing port 10, and said circular grooves 3-5 and the hollow part 21 are packed with the sand without a gap. After packing of the core sand has been completed, hardening gas is blown in from the packing port 10, and the core sand is hardened integratedly. Thereafter, by disassembling the forming mold, a core 30 in which a cylindrical part 30a and the piece 20 have been formed integratedly is obtained.
