Title:
CASTING METHOD AND APPARATUS
Document Type and Number:
Japanese Patent JP2012121072
Kind Code:
A
Abstract:

To eliminate the use of green sand by replacing green sand molds with all core sand assemblies that provide, during casting, both the internal and external surfaces of a casting, such as a cylinder head or engine block.

A mold assembly (20) is formed from the same core sand that is used to form core elements (23) defining the internal passageways of the casting. A mold-core carrier (10, 30, 40) is constructed with tapered sides (11, 31, 41) that hold an assembled mold (21, 22) and core elements (23) together during pouring of the molten iron alloy into the mold-core assembly (20) and the cooling period to form the casting. After the casting is formed, the core sand from both the mold elements (21, 22) and the core elements (23) is recovered, and may be recycled and processed to form further mold elements or core elements or both.
