Abstract: A process and a device are proposed for the casting and unpacking of clusters which, after the casting, after passage over a primary cooling path, are freed by jolting from the surrounding molded clump consisting of mold sand, whereupon, after passage over a secondary cooling path, the individual castings are separated from the cluster. The cluster is cast with a hanger which is present in front in the direction of transport, and the molded clump is conveyed over a discharge shaft for old sand against a transport hook in the manner that the hanger with the transport hook suspended, swings downward, throwing off the predominant quantity of old sand from the molded clump, whereupon the cluster is jolted.
