Title: Casting method and apparatus
IPC: B22C9/02
Filed: 2000-06-30
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 tapered sides that hold the assembled mold and core elements together during pouring of the molten iron alloy into the mold-core assembly and the cooling period to form the casting. Although the carrier sides can use a refractory liner, preferably the sides are made of replaceable sheet metal backed by an open structural framework to enhance cooling of the casting. After the casting is formed, the core sand from both the mold elements and the core elements is recovered, and may recycled and processed to form further mold elements or core elements or both.
