Abstract (en)
[origin: EP0122116A2] In a machine for the simultaneous production of a pair of associated upper and lower casting mould parts in pressing chambers (3, 4) which are movable towards and away from an intermediate pattern carrier (5), and for joining the mould parts after drawing off and lateral removal of said carrier, the pressing chamber walls (13, 14) have sand introduction openings (22) as well as evacuation ports (16) which by displacement of the walls in relation to the pattern carrier come into and out of position to communicate with a sand store (2) and a vacuum source, respectively, in order to produce vacuum in the chambers.
