Apparatus for moulding foamable thermoplastic synthetic materials comprises a mould having a vapour chamber (5, 5') in each half, which half- moulds (1, 2) are relatively movable apart (arrow A) and each contains a mould lining (11, 12) into which the foamable material is received, wherein each vapour chamber is closable by a plate (8, 8') movable therefrom to form a gap connecting the chamber inner space with atmosphere for heat dissipation. One or both vapour chamber frames (5, 5') may be separated from the corresponding mould frame (6, 6') for further heat dissipation. A cooling medium spray tube (3, 3') may be provided inside one or both half- moulds, preferably within the vapour chambers, and directed onto the mould linings, and also a suction blower may create cooling on one or both half- moulds. <IMAGE> |
