MOULDING PROCESS

Making moulds

A method of making a female mould includes the steps of pressing a male pattern of a material of which the index of strain rate sensitivity (m) is less than 0.35 into a block of an alloy in a superplastic state by a slow speed pressing operation whereby to form the female mould form in which the required object may be cast or moulded. In a first example, a male pattern of high speed steel is pressed into a superplastic block to form the female mould. The female mould cavity is then chromium plated. A male form is moulded by pressing further superplastic material into the female mould. The male form is then nickel plated. Polycarbonate female mould shells are then moulded around the male form. The polycarbonate female mould shells are then used to make confectionary. In a second example, a male pattern of high speed steel is pressed into a superplastic block to form a female mould. The female mould is then used for moulding rubber.

The wire electric discharge machining process can also be used to cut the face gear tooth (47) directly, to thereby circumvent the forging procedure. The complex, curved surfaces of the face gear teeth (47) are mathematically approximated with a ruled surface, and the mathematical approximation is input to the wire electric discharge machining apparatus for subsequent execution and forming of the die.

Die reinforcing method and die repairing method

A mixed powder layer is applied by coating to a cavity of a forging die made of an Fe-base alloy, at least to the region of the cavity to be reinforced or repaired, the mixed powder layer comprising the first element powder capable of being converted into a carbide to enhance the hardness of the forging die and the second element powder having a melting point lower than that of the first element powder. Die reinforcing is carried out by forging a work by using a forging die covered with the mixed powder layer and heat-treating the die by utilizing the working heat generated in the forging to thereby make the layer reflow and diffuse the carbide in the die.
