ABSTRACT:
An apparatus for the production of cores from fluidized sands in hot boxes comprises individual mechanisms for joining and disjoining top and bottom sections of core boxes, which are placed beyond the confines of the latter. The joining mechanism incorporates at least two spring-loaded grapples mounted on individual shafts, fitted in satellites and positioned on a transport device, so as to carry core boxes. Located at one end of each grapple is a wedging member which co-operates with a wedging member provided on the top section of each core box. The disjoining mechanism includes stops, positioned on a support frame, and rollers mounted on the other end of each grapple for interaction with the stops.
