The machine has a chassis 1 in which is established a casing based on a fixed body 15 and a movable body 16, the latter being actuated by means of cylinder 18, to which casing it is possible to apply a vacuum in a closed situation, said casing housing, with the possibility of rotation, the sand mould 14 established in turn in the central rotary body 23 of a support 21 which can be displaced by means of another cylinder 22 towards a lower nozzle 13 which supplies the mould 14 with the relevant metered amount of molten metal from a lower metering reservoir 6 into which is introduced a pressurized fluid via a connection 10, said reservoir 6 receiving the molten metal from a larger, surrounding reservoir 3, with the collaboration of an obturator 8 controlled by a level sensor 9. <IMAGE>
