Abstract

1,080,541. Reclaiming foamed resins; moulds. JABLO PLASTICS INDUSTRIES Ltd. Jan. 6, 1965 [Jan. 6, 1964], No. 533/64. Heading B5A. A mould, particularly intended for the reclaiming of foamed thermoplastic resins such as foamed polystyrene, comprises a lower cavity portion formed by walls 21 and a base 5, an upper cavity portion of greater horizontal cross-sectional area than the lower portion and formed by walls 23, and a lid 3 having a flange 16 which rests on a shoulder 24 between the cavity portions when the lid is lowered by hydraulic jacks 38. The base 5 and lower surface (10) of the lid, Fig. 1 (not shown), are perforated as at (18) and compartments are formed in the lid and base of the mould cavity which receive steam through pipes 17, Fig. 2, condensate exiting via pipes 20. One wall 21 of the lower cavity portion is in the form of a flap 28, which is attached to levers 29 having counterbalances 32 so that it is normally held upright, but which may be swung outwardly to allow removal of the moulding. Normally, the mould cavity is filled to the mouth with material, the lid 3 acting as a compression plunger in its descent to shoulder 24. Asbestos seals 27 and 33 are provided and the upper cavity portion may be raised when the lid is raised by connecting bolts 34 to brackets 37. This facilitates filling of the lower portion of the mould only, when it is not intended to compress the moulding material. Steam chambers may also be formed by providing double walls for the lower cavity portion and the mould may be made of steel lined with aluminium alloy.
