METHOD OF SIMULTANEOUSLY MANUFACTURING A PLURALITY OF CRANKSHAFTS

摘要

A method of simultaneously manufacturing a plurality of crankshafts includes positioning a single core within a cavity of a mold having a first half and a second half together forming an exterior shape of the plurality of crankshafts. The exterior shape of each of the plurality of crankshafts produced thereby includes a plurality of pin bearing journals and a plurality of main bearing journals. The method also includes introducing via a mechanism into the cavity a molten metal to form the plurality of crankshafts. As the molten metal flows into the cavity and around the single core, a hollow section extending through at least one of the plurality of pin bearing journals and at least one of the plurality of main bearing journals of each of the plurality of crankshafts is formed. A system for simultaneously manufacturing a plurality of reduced mass crankshafts using the above method is also disclosed.
