A device (10) for producing moldings composed of a moldable foam has a multiplicity of sub-molds (11, 12) which in each case have a sub-cavity (14). The sub-cavities (14) act together to form a molding cavity (K). At least one of the sub-molds (11, 12) has a feed channel (35) through which plastics beads can be introduced into the molding cavity (K), and a steam chamber (24) from which superheated steam can be introduced through at least one steam channel (18) into the molding cavity (K). The at least one sub-mold (11, 12) has a first mold segment in which the sub-cavity (14) is present and a second mold segment in which the steam chamber (24) is present. The first mold segment has a first temperature-control system (15), and the second mold segment has a second temperature-control system (20).
