Abstract
PURPOSE:To enable the casting of high quality having no structural defect and the improvement in productivity by promoting the directional solidification of the molten metal inside a cavity by the combination of the thermal conductivity of at least >=two kinds of different materials and the thermal capacity based on the mass. CONSTITUTION:A sand core 86a or 86f is arranged at the specified part of a cavity 42 formed inside a casting die 32. A die closing is then executed by displacing an upper die 36, sliding dies 38a, 38b and 40a, 40b by approaching them to a lower die 34. Then, the molten metal melting an Al alloy is filled up inside a cavity 42 from the sprue 45 formed on a nozzle 46 via a stoke 47. Now, after holding the pressurizing state for the specified time a compressed air is drawn to solidify the molten metal. For the lower die 34 and upper die 36 and sliding dies 38a, 38b, 40a, 40b the material of different thermal conductivity is used respectively and also the mass is composed by combining selectively. The heat radiation of the molten metal is adjusted on each respective part and the solidification is executed with having the directivity in the order of the upper die 36 sliding die 38a, 38b, 40a, 40b and the lower die 34.
