Abstract
1297944 Moulding plastic material DUNLOP HOLDINGS Ltd 12 March 1970 [18 March 1969] 14265/69 Heading B5A [Also in Division F2] A mould, Fig. 2, for an insulation sleeve of cellular rubber or plastics material, Fig. 1, is substantially cylindrical and has a rod-like member 21 and extension 22 to produce the bore 11 and split 13 in the sleeve. In the embodiment shown the mould is in two halves, hinged at 18, with locking devices 19 and 20. The rod which may be longer than the mould, is supported by slots in the end surfaces of the mould and the extension 22, which may be integral with the rod, is clamped between the edges 23, 24 of the mould halves when the mould is closed. Other methods of supporting the rod are by a bar across each end face of one half of the mould or by one bar on each half of the mould. The extension may alternatively be formed so that it locks with a corresponding section of each end face. The moulding operation is conveniently carried out by inserting a liquid precursor of the cellular material and then foaming the material, e.g. by the application of heat. The extension 22 is preferably positioned vertically to allow the escape of air from the mould as the foam expands and prevents the formation of undesirable voids. Another method of forming the sleeve is by hot-wire cutting; the split may be cut in a pre-bored cylinder using a split-shaped length of wire (26), the wire may be shaped to cut the bore and split simultaneously (25) or finally an outer circle of wire (28) may be added so that the sleeve can be cut completely from a non-cylindrical block (Figs. 3 and 4, not shown).
