ABSTRACT:
A system for producing foundry molds providing a device for filling empty mold boxes with mold forming material at a filling station includes a first rotary shifting device and a second rotary shifting device located on opposite sides of the filling station. The first shifting device operates to shift pattern devices from the filling station to a first shifting station while simultaneously moving another pattern device from the first shifting station into position at the filling station. Likewise, the second shifting device moves mold halves from the filling station to a second shifting station while simultaneously moving an empty mold box from the second shifting station to the filling station. The pattern devices are moved to and from the first shifting station by a first conveyor device and the empty mold boxes and the mold halves are moved to and from the second shifting station by a second conveyor device which extends generally parallel to the first conveyor device. A third parallel conveyor device transports assembled filled mold boxes and pattern devices from the filling station to a single-station mold forming unit.
