Abstract

A foundry for automatically making sand castings, in which a metal casting and sand cake are transferred to a container after partial cooling and are carried with the container to a storage zone to cool for a time independent of any restrictions imposed by the conveying path, conveying speed, or cooling time required by other castings being processed. During handling and cooling, the integrity of the sand cake about the casting is maintained to provide cooling characteristics desirable for complex castings with variations in wall thickness. Specific structures handle and convey the sand cake and casting efficiently and reliably. Associated structure fabricates the sand molds and pours the castings, all in a continuous process.
