Abstract
972,195. Injection moulding. W. J. STOKVIS' KONINKLYKE FABRIEK VAN METAALWERKEN N.V. May 17, 1961 [May 25, 1960], No. 18028/61. Heading B5A. In a method of injection-moulding an object comprising a plurality of cylindrical hollow parts plastic moulding material, e.g. P.V.C., is distributed throughout the mould from an injection place in or near the intersection point of the centre lines of said parts, or in or near the intersection point of the centre line of one of these parts with the plane of symmetry through the other part. As shown in Fig. 1, a T-shaped fitting 3, 8 is formed in a mould 1, 2 having separate cores 4, 5, 6 in any one of which a sprue channel 7 is provided. Alternatively, any one of the cores may be formed by the nozzle of an injection moulding machine (not shown). Channels 10, 11, 12 between adjacent ends of the cores distribute the moulding material from the end 9 of sprue channel 7. As shown in Fig. 2, the sprue channel 16 may be formed in the mould-half 1 in alignment with a channel provided by semi-cylindrical grooves 14, 15 in adjacent ends of cores 4, 5 through which moulding material enters channels 10, 11, 12. The sprue and partitions formed by the channels are removed when the filling has been taken from the mould.
