Abstract:
A mold handling system for use in a sand mold casting machine having a mechanism for producing a plurality of sand molds, a mechanism for pouring molten material into the sand molds to form castings, and a mechanism for removing the sand from cooled castings, the mold handling system comprising:a two-tiered conveyor interposed between the mechanism for producing a plurality of sand molds and the mechanism for removing the sand from the cooled castings, the two-tiered conveyor having an upper linear track and a lower linear track, the lower linear track disposed at a lower vertical elevation relative to the upper linear track; a plurality of mold pallets carried on the upper and lower linear tracks along an endless path about the upper and lower linear tracks; a mold inlet on the upper track for receiving molds on to the two tiered conveyor; and a mold outlet on the upper track for transferring molds off of the two tiered conveyor toward the mechanism for removing the sand from cooled castings.
