Abstract

1,273,066. Casting machines; moulds. NATIONAL LEAD CO. 24 Dec., 1969 [26 Dec., 1968], No. 62787/69. Heading B3F. A pressure die-casting 45 is made by injecting metal into an assembly of die elements 10, 12, 13, 15, 16, 17 and pins 21, 22 (shown in exploded form) held together in holders (40, 41) between the platens of a die-casting machine, then removing the assembly with the contained casting 45 (by ejector pins 38, 39) and disassembling the die elements. After heating and lubricating by immersion in a hot bath of graphite suspension, with subsequent drying, the die elements are re-assembled for further casting. The die elements include coring elements 11-13. Mechanical, pneumatic or hydraulic forces may be used to disassemble the elements which may be loosened from the casting by vibration.
