  • Patent number: 10493523
    Abstract: An integrally-formed metal-casting mold loaded with a solid-metal ingot in an ingot-cup portion thereof is heated in a furnace under vacuum to a temperature sufficient to melt the solid-metal ingot. The ingot-cup portion is operatively coupled to a component-mold portion of the mold via a funnel portion thereof, either directly or through a riser portion operatively coupled to a base of the component-mold portion, which provides for feeding molten metal melted from the ingot to cast a part in the component-mold portion. Molten metal in excess of what is needed to cast the part flows either into the riser portion, or into a fluid conduit that extends above the component-mold portion. The molten metal may be fed to the component-mold portion through a molten-metal filter to reduce flow rate or remove contaminants. The mold may be formed either as an investment mold or directly by additive manufacturing.

    Abstract: 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.
