METHOD OF SIMULTANEOUSLY MANUFACTURING A PLURALITY OF CRANKSHAFTS

摘要

A method of simultaneously manufacturing a plurality of crankshafts includes positioning a core system having a plurality of individual cores within a cavity of a mold having first and second halves forming an exterior shape of the crankshafts. The crankshafts' exterior shape includes a plurality of pin bearing journals and a plurality of main bearing journals. Each of the cores passes through each of the crankshafts. At least one core passes through at least one of the pin bearing journals and at least one other core passes through at least one of the main bearing journals. The method also includes introducing into the cavity molten metal to form the crankshafts. As the metal flows into the cavity and around the plurality of cores, a hollow section extending through at least one of the pin bearing journals and at least one of the main bearing journals of each crankshaft is formed.

1. A method of simultaneously manufacturing a plurality of crankshafts, the method comprising:
positioning a core system having a plurality of individual cores within a cavity of a mold having a first half and a second half forming an exterior shape of the plurality of crankshafts, wherein:
the exterior shape of each of the plurality of crankshafts includes a plurality of pin bearing journals and a plurality of main bearing journals, wherein each of the plurality of individual cores is formed to pass through each of the plurality of crankshafts; andat least one of the plurality of individual cores has a shape that passes through at least one of the plurality of pin bearing journals and at least one other of the plurality of individual cores has a shape that passes through at least one of the plurality of main bearing journals; and introducing into the cavity via a mechanism a molten metal to form the plurality of crankshafts, including flowing the molten metal into the cavity and around the plurality of individual cores to simultaneously form 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.
