Abstract

832,736. Moulding sealing rings. BULWELL PRECISION ENGINEERS Ltd. Oct. 28,1958 [Oct. 29, 1957], No. 33643/57. Class 87(2). Rubber sealing rings are moulded under pressure in a two-part mould comprising a pair of thick circular plates 1, 2 with complementary half-moulds 3, 4 in their opposed surfaces. A taper dowel 9 projects upwards from the lower plate along the central axis and is engaged by a tapered socket 10 projecting downwards from the upper plate. The dowel 9 may be protected by a spigot 11 of reinforced plastic. A tapered wedge 12 on the outer periphery of the upper plate 1 is adapted to fit in a tapered slot between members 15, 16 on the periphery of the lower plate 2 variation in radial expansion between the plates thus does not result in distortion. Minor modifications in the design and location of the dowels and wedges are mentioned.
