Abstract
An automatic core setting machine having a movable mask with pockets for holding foundry cores until the mask is brought into face-to-face abutment with a mold, and a vacuum system comprising a body member integral with the pocketed mask and defining an interior suction chamber, the body member comprising a first wall having means defining a plurality of inlet ports terminating on the interior surface of the first wall in a plurality of injector nozzles, a second wall parallel to the first wall and having means defining a plurality of outlet ports terminating on the interior surface of the second wall in a plurality of ejector nozzles, each of the plurality of outlet ports being axially aligned with one of the plurality of inlet ports, and side walls rigidly connecting the first wall and the second wall and defining a space therebetween; means defining a suction opening through at least one of the side walls, the suction opening communicating with the interior suction chamber of the body member; means for connecting the side wall suction opening to the core pockets of the mask; a pressurized air source; and means for injecting pressurized air into the plurality of inlet ports.
