Title: DEVICE AND PROCESS FOR PRODUCING MOULDINGS COMPOSED OF A MOULDABLE FOAM
Abstract:
A device (10) for producing mouldings composed of a mouldable foam has a multiplicity of sub-moulds (11, 12) which in each case have a sub-cavity (14), wherein these sub-cavities (14) act together to form a moulding cavity (K). At least one of the sub-moulds (11, 12) has a feed channel (35) through which plastics beads can be introduced into the moulding cavity (K), and a steam chamber (24) from which superheated steam can be introduced through at least one steam channel (18) into the moulding cavity (K). The at least one sub-mould (11, 12) here comprises a 1st mould segment in which the sub-cavity (14) is present and a 2nd mould segment in which the steam chamber (24) is present, where the 1st mould segment has a 1st temperature-control system (15) by means of which the 1st mould segment can be heated and/or cooled to a predetermined temperature, and where the 2nd mould segment has a 2nd temperature-control system (20), by means of which the 2nd mould segment can be heated and/or cooled to a predetermined temperature. A process for producing a corresponding moulding with use of a corresponding device (10) is moreover explained.
