PRESSURE CASTING APPARATUS AND PRESSURE CASTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pressure casting apparatus in which there is no need of specially providing a cooling fixture, further, limitation is not given to injection time, its setting can be freely performed, and a semi-solidified metal can be filled into the cavity of a mold and the yield of a casting can be improved by a simple equipment constitution similarly to the ordinary die casting, and to provide a pressure casting method.;SOLUTION: Regarding the pressure casting apparatus 10, a semi-solidified metal slurry 62 is injection-molded into the cavity 22 of a die 12 to mold a casting. The apparatus 10 includes: an injection sleeve 24 fitted to the die 12 and obtaining a semi-solidified metal slurry 62 from the fed molten metal 60; and a plunger 26 inserted into the injection sleeve 24 and injecting the semi-solidified metal slurry 62 into the cavity 22 of the die 12. The injection sleeve 24 is provided with a heat insulating part 38 at the side of the die 12 and is provided with a cooling part 40 at the side of the plunger 26.;COPYRIGHT: (C)2011,JPO&INPIT
