Abstract
A nickel shell for molds formed by nickel vapor deposition having incorporated therein a combination steel parting line and manifold and a plurality of heating and cooling lines operatively connected to the manifold for the flow of heating or cooling fluid therethrough, said heating and cooling lines, and other mold components such as injection nozzles and mold vents, being encapsulated within the nickel shell.
Claims5
A nickel shell mold formed by nickel deposition comprising a nickel shell having a desired configuration, a peripheral steel parting line surrounding said shell, means integrally securing said shell to the parting line, said parting line having a manifold formed at each end of the mold extending substantially across the width of the mold, connection means formed in each manifold for receiving external fluid lines, a plurality of fluid lines having the configuration of the mold extending across the mold from one manifold to the other for communicating heating or cooling fluid from one manifold to the other, said plurality of fluid lines and adjacent portions of the manifolds being encapsulated into the body of the nickel shell for efficient heat transfer.
