FORMMASCHINE

A moulding machine for producing shaped parts from a mixture of solid and liquid components, comprises a frame 1 mounting a hopper 4 for a filler component 5, and a mixing device 10 carrying a hopper with a dosing means 37 for a binder component and having a feed unit 14 for the liquid component. The mixing device 10 is a double-walled vessel, defining a fluid- tightly closable mixing chamber 11 heatable by a heating fluid 34 in a cavity formed between the vessel walls. The vessel outer walls 32 are at least partly thermally insulating. The mixing device 10 has orifices 12 and 13 for feeding the solid components of the moulding mass and a discharge orifice 16 closable by a member 15 on the end of a mixing shaft 22 and driven by a motor 24. A pressurised gas is introduced into the mixing chamber 11 to discharge the finished moulding mass, upon opening of the discharge orifice 16, into a mould 36 supported on a raisable and lowerable table 2.
