Abstract
PURPOSE: To enable the core sand to prevent generation of shrinkage cavities in the cost product owing to a difference between the cooling speeds of the outer wall of the mold and the core, by preparing the core sand as a mixture of the shell sand and powder of metal possessing a good thermal conductivity.
CONSTITUTION: In the case of manufacturing such a cast product possessing a thin walled partition as an engine's intake-manifold made of an aluminum alloy, for example, by the low-pressure casting method, the molten metal rises up under a pressure through the runner 3 within the cruicible 2. The molten metal fills up the cavity formed by the main mold comprising the upper and lower molds 4, 5, and the cores such as the jacket core 6, the port core 7, etc. When the molten metal in the product part solidifies, the pressure is immediately interrupted and reduced, and the excessive molten metal is recovered. In the present method, the cores 6, 7, are prepared from a mixture of the shell sand and powder of iron or steel, for example. Hereby, the cooling speed of the molten metal, especially in the cavity 8 for casting the partition to be formed by cores, can be increased.
