HIGH-VACUUM DIE CASTING METHOD, CAPABLE OF MAINTAINING A SLEEVE TEMPERATURE WITH 150amp;deg;C TO 200amp;deg;C

摘要

PURPOSE: A high-vacuum die casting method is provided to lengthen a service life by preventing a bending of a sleeve, and to prevent a lower part of the sleeve in a high temperature state from being eroded by a molten metal.;CONSTITUTION: A high-vacuum die casting method which maintains a sleeve temperature with 150°C to 200°C comprises the following steps: in an injection of a molten metal, a temperature of an entrance of a sleeve (310) which injects the molten metal to an inside of a cavity of a mold maintains with 150°C to 200°C; and a temperature of a lower part of a part where the sleeve is not fixed maintains with 150°C to 200°C by mounting a copper alloy radiator on the lower part.;COPYRIGHT KIPO 2013
