In the method a unit with mold cavities for at least two mold parts to be interconnected is moved under a shooting station, which is provided with at least two shooting heads and sand magazines with separate shooting hood shoot-out areas and from the magazines sand is shot into the mold unit cavities for the different mold parts with different pressures and different sand compositions.

Abstract: A method and apparatus for improving kinematic characteristics and for obtaining greater variability with respect to the use possibilities when handling core parts for providing a read-to-cast core stack, wherein, following a removal from a core shooting machine, the core parts are assembled at a stacker to form a core stack, introduced into a dipping bath and subsequently supplied in a correct position to a casting machine. The stacker, successively stacks in each case an upper core or an already assembled core part stack, with the upper core part or the already assembled core part stack being exclusively linearly raised and, in each case, a lower core part is held in a floating manner by an air cushion, whereas the raised core part or core part stack is lowered onto the lower core part for assembly.

Abstract: For a production of foundry moulds, dies are stepwise, cyclically conveyed by a continuous conveyor and, synchronously with the dies, shot hoods are conveyed into a shot station which is common to both the dies and shot hoods, with the shot hoods being displaced with respect to the dies. For this purpose, a cyclically revolving die conveyor is provided for the dies, and a further conveyor is provided for the shot hoods, with the further conveyor revolving synchronously with the die conveyor. At least one shot station may be provided which is common to several dies and may be associated with the die conveyor in which dies and the associated shot hoods are conveyed by the die conveyor in a reciprocally displaced manner.

Abstract: A core or shell blow (shoot) machine, equipped with a quick core-box change device, makes it possible to carry out a quick core-box change in just a few minutes, thereby reducing down time. For this purpose, the core-box change device consists of a twin carrier which is swung hydraulically in a horizontal plane about a vertical axis. The care-box in the machine, after picking up the cope and the cope ejector plate, is lowered by the lift table into the carrier, after hydraulic clamps between the table and the core-box bolster have been released. The core-box change device is then rotated 180.degree., which swings the old core-box out of the machine and, simultaneously, swings the new core-box stack-up into the machine over the lift table. In the meantime, the old blow-plate is removed from the sand magazine, outside of the machine, using the blow-plate removal device.
