ABSTRACT:
A mold used in centrifuge casting is cooled by taking advantage of inherent characteristics of the centrifugal casting process, and in particular the shape of the remaining sprue. The sprue has a conical profile and a conical depression formed by a vortex which results from the spinning mold. The cooling apparatus comprises a housing and plunger which engage the surface of the sprue and draw heat from the mold. Thermal conduction from the hot metal through the runners and sprue to the cooling head allows a mold to cool faster than traditional methods.
