Abstract

A mask having pockets for holding foundry cores is swung downwardly and laterally from a core receiving position to a presetting position and then is lowered vertically to set the cores into the cavities of a sand mold. When the mask is in its receiving position, the top of the mask is tilted downwardly towards the mold and the pockets face outwardly to facilitate easy loading of the cores into the pockets without the application of vacuum. As the mask is swung downwardly and inwardly, it is turned to cause the pockets and cores to face downwardly (with the application of vacuum) preparatory to the cores being lowered vertically into the mold cavities.
