Abstract
A two tiered mold handling system for use in a sand mold casting machine which comprises a two tiered conveyor for pouring and cooling, or a two tiered conveyor for cooling only. The two-tiered conveyor has an upper linear track and a lower linear track disposed at a lower vertical elevation. The tracks carry a plurality of mold pallets along an endless path around the upper and lower linear tracks. The application is directed toward several concepts including two tiered pouring conveyors in combination with two tiered cooling conveyors, two tiered combination pouring and cooling conveyors, and one tiered pouring conveyors in combination with two tiered cooling conveyors to provide a lower pouring elevation.
Claims15
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 a linear upper track and a linear lower track, the linear lower track disposed at a lower vertical elevation relative to the linear upper track;
- a plurality of mold pallets carried on the linear upper and lower tracks along an endless path, each mold pallet having a plurality of adjacent mold receiving locations such that each mold pallet is adapted to receive at least two sand molds side by side;
- and
- first and second elevators at the ends of the upper and lower tracks, the elevators moving mold pallets between the upper and the lower tracks.
