Abstract
A hybrid casting process for structural components uses a re-usable metallic mold rather than a sand mold to produce more consistent cast components. The hybrid casting process uses a metallic mold coupled to a core mold to produce the near net shape of the cast component. Machining operations are performed on the near net shape cast component to produce a final component that meets tolerances and other specifications of the structural component.
Claims11
A casting assembly for producing a structural component, the casting assembly comprising:
- a metallic mold comprising:
- walls defining surfaces of the structural component;
- a heating device coupled to the metallic mold, wherein the heating device is configured to increase the temperature of surfaces of the metallic mold by:
- heating a first portion of the metallic mold during the solidifying of the metallic material within the metallic mold;
- and
- heating a second portion of the metallic mold during the solidifying of the metallic material within the metallic mold;
- and
- a cooling device coupled to the metallic mold, wherein the cooling device is configured to decrease the temperature of surfaces of the metallic mold by:
- cooling a third portion of the metallic mold during the solidifying of the metallic material within the metallic mold;
- and
- cooling a fourth portion of the metallic mold during the solidifying of the metallic material within the metallic mold;
- and
- a core positioned within the walls of the metallic mold.
