Title: Casting method of casting
Inventor: NAKAMURA YUUICHI
IPC: B22D15/02
Filed: 1983-11-08
Abstract: PURPOSE:To prevent cracking and to reduce cost by packing fluid sand into the hollow parts of hollow cores and removing only the fluid sand at the optimum timing after the cast steel starts solidifying. CONSTITUTION:Fluid sand 3 is packed into the hollow parts 1b, 2b of hollow cores 1, 2 and the sand discharge hole 2c in the lowermost part is closed. When the melt of a cast steel is poured through a sprue into a casting mold, the melt rises up to risers through gates 10 and body part 100. The hole 2c is opened at the optimum timing (right after starting solidifying in solid) since the cast steel starts solidifying until the solidification is completed and the ordinary temp. is attained then only the sand 3 is removed. The cores 1, 2 deform on shrinking of the cast steel and collapse before the ordinary temp. is attained. The shrinkage resistance of the cast steel is relieved by the above-mentioned method by which cracking is prevented and the cost is reduced.
