METHOD AND APPARATUS FOR PRODUCTION OF ALUMINUM ALLOY CASTINGS

摘要

Method and simplified apparatus for manufacturing aluminum alloys castings, for example those cast aluminum parts utilized in the manufacture of automobile engines: cylinder heads, engine blocks and the like; whereby the castings are cast in a plurality of semi-permanent-type molds, said molds each being movable to a plurality of processing positions along one of a plurality of straight line paths (five in the preferred embodiment), wherein the operations of cleaning, core setting, casting, and casting extraction are performed on each mold at predetermined positions along its respective path and alternating said operations among the molds in order to permit minimization of the number of robot equipment and to increase the aggregate productivity of said molds, since any one processing operation is handled by only one robot arm moving between the plurality of lines seriatim, so that a given process step is performed at any one time only at one of the plurality of lines.
