Abstract

An apparatus for cleaning shot hoods during the manufacture of casting molds or core packets that are ready for casting, by means of core shooters or shooting stations, preferably in a linear arrangement, the core shooters in each instance incorporating a shot hood (3) that comprises a shot plate (1) and shot nozzles (2), it being possible to uncouple the shot hood (3) from the core shooter and lay it on a pallet (4) or the like with the shot nozzles (2) pointing downward, characterized by a delivery system (5), a transfer station (6), an emptying station (7), a flushing system (8), a drying system (9), an exit station (10), optionally an inspection station, and a removal system (11), the shot hood (3) that has been laid upon the pallet (4) being moveable from the core shooter to the transfer station (6) by means of the delivery system (5), it then being possible to raise it from the pallet (4) by means of a first manipulator (12) and pivot it through approximately 180.degree. about a horizontal axis (13) and then move it with the shot nozzles (2) pointing upward to the emptying station (7), in which it is emptied, to the flushing system (8), the drying system (9), and then to the …
