  • Patent number: 6857462
    Abstract: A high pressure die casting method including providing first and second accumulator assemblies, wherein the first accumulator assembly provides pressurized fluid toad die assembly while the second accumulator assembly provides pressurized fluid to remaining portions of the die casting machine. A barrel insert loader inserts cylinder barrels into the die assembly, and then the dies are closed to permit molten aluminum to be injected therein and thereby form the cast engine block. The dies include side gates and sub-gates through which molten aluminum is introduced into the mold. The dies are opened, and the cast engine is removed from the dies by operation of a robot arm, and a die spraying assembly is inserted between the open dies and sequentially sprays the dies, to clean and cool the dies in preparation for a subsequent casting operation.
