Abstract
1. Apparatus for the production of moulded parts of any shape desired from foamed plastics material, preferably expandable polystyrene, in which the shaping takes place in two mould cavities separated from one another and each have a die (4,7 or 44,77), a core (17) and a hood (5,6 or 55,66), one of which mould cavities is kept permanently hot and the other one of which is kept permanently cold in such a way that the hot mould cavity is filled with foam pellets and these latter, by feeding in a heating medium, preferably steam, are bound to form a preform, whereupon this preform is transferred to the cold mould cavity for the purpose of final shaping and stabilisation, characterized in that the core (17) of only one of the two mould cavities is arranged on the hood (5 or 55) and the core (17) of the other mould cavity is arranged in the die (7 or 77), and in that the hot and cold mould cavities are arranged in series in a straight line (16), the die (4 or 77) of the hot mould cavity and the die (7 or 44) of the cold mould cavity being arranged on a respective travelling table (1,2) movable on the straight line (16), and the hood (5 or 66) of the hot mould cavity and the hood (6 or 55) of the cold mould cavity being arranged together on an intermediate table (3) movable out of said straight line (16), and the preform (9) situated in the die of the hot mould cavity can be transferred directly into the die of the cold mould cavity when the intermediate table (3) is moved out of the straight line (16).
