摘要
A method is proposed for the preparation of wax patterns for casting small, intricate components and equipment for casting such components. A master pattern (2) is made, of a material which can withstand vulcanisation and will retain its shape. The master pattern is placed in a mass of raw rubber, which is compressed and vulcanised afterwards. The rubber is cut in two, the master pattern is removed and the rubber mould halves (3,4) are joined. The proposed equipment comprises the following:- the base (6) is arranged for rotation by an electric motor, around a point (7) the molten metal feeder (8) is located away from this point, and is connected to the casting mould (9). The molten metal feeder (8) is arranged on the base (6), so that it can be tilted radially. The molten metal feeder (8) itself comprises the following:- melting crucible (10), surrounded by a high frequency coil (11), tilting mechanism (12), and holder mechanism (13) for the moulds.
