METHOD OF MANUFACTURING METAL MOLD

摘要

PURPOSE: A method of manufacturing a metal mold is provided to produce metal molds promptly as much as a user wants by applying rapid/vacuum molding technologies. CONSTITUTION: A couple of insert metal molds(90,90') are made by forming gates on the side of reverse metal molds, covering with a mold frame and injecting metal-mixed powder resin. Herein, the metal-mixed powder resin consists of an epoxy as a thermosetting resin and 7% of Ni-Fe powder having average density of 2000 mesh. The metal-mixed powder resin is injected into the mold frame and then hardened at a specific temperature. Finally, the insert metal molds(90,90') are obtained by removing the reverse metal molds.
