ABSTRACT:
Molds are conveyed from the delivery end (2) of a molding machine (1) to a cooling conveyor (3) or an extractor station. By this procedure the molds (4) are principally conveyed in a direction away from the molding machine in close contact with each other on the first conveyor (5), where the pouring takes place. Then the molds (4) are conveyed back in the direction of the molding machine (1) on a second conveyor (6) running parallel to the first conveyor, on which second conveyor the initial cooling and solidification takes place. The molds with the partially cooled castings are then pushed on to a cooling conveyor (3) or an extractor station by the action of a reciprocating ejector element (7). The molds (4) are checked when being delivered from the molding machine (1), and molds (4') with irregularities or flaws are pushed away transversely (8) from the first conveyor (4) in the direction of the second conveyor (6) immediately after having left the molding machine (1), after which the molds (4) are conveyed on away from the cooling conveyor (3) or the extraction station by the action of an ejector element (7). The ejector element (7) has an ejector blade (12), which can be swung up above the level of the molds (4), whereby a pallet cross-conveyor (8), which is adapted to move empty pallets between the two conveyors can at the same time be used during its return stroke to take molds (4') direct from the delivery end of the molding machine to the ejector position at the exit end of the second conveyor (6).
