Abstract
The use of green sand is eliminated 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. In the process, a mold is formed from the same core sand that is used to form the core elements defining the internal passageways of the casting. A mold-core carrier is constructed with downwardly converging sides that hold assembled mold and core elements together, without fasteners, during transportation and pouring of the molten iron alloy into the mold-core assembly and the cooling period to form the casting. After the casting is formed, the core sand from both the mold elements and core elements is recovered, and may be recycled and processed to form further mold elements or core elements or both.
