초록

A system for producing cast components from molten metal. One form of the present invention includes a system for the precision pouring of molten metal within a casting mold.

대표청구항 ▼

1. A method for producing a cast component, comprising: forming a thin shell ceramic casting mold with a core integral therein by photopolymerization of a ceramic filled resin, wherein a portion of the mold formed by the photopolymerization of a ceramic filled resin extends to the core and is configured to provide orientation of the core during a molten metal pouring operation;pouring a molten metal into the thin shell ceramic casting mold; andactively moving a thermal gradient through the molten metal within the thin shell ceramic casting mold to cause solidification into a cast component with a single crystal or directionally solidified microstructure, wherein the actively moving involves one of varying a flow rate of a fluid through a conduit in a conductive thermal relationship with the molten metal to provide heat conduction into the metal poured into the thin shell ceramic casting mold. 2. The method of claim 1, which further includes supporting the thin shell ceramic casting mold during said pouring. 3. The method of claim 1, wherein the thin shell ceramic casting mold is free of any substantial additional external support during said pouring. 4. The method of claim 1, wherein said forming includes producing a wall thickness within a range of about 0.020 to about 0.080 inches. 5. The method of claim 1, wherein in said forming the at least one core is hollow. 6. The method of claim 1, wherein said forming includes producing the thin shell ceramic casting mold having at least one casting mold surface to define an external surface on the cast component and the integral core defines at least one opening within the cast component. 7. The method of claim 6, wherein said forming produces a plurality of cores integrally formed with the ceramic casting mold, wherein each of the plurality of integral cores is adapted to form an internal feature within the cast component. 8. The method of claim 1, wherein said forming produces a casting mold having a wall thickness of about 0.020 inches. 9. The method of claim 1, wherein the molten metal pressure within the thin shell ceramic casting mold is within a range of about three to about twenty-four inches of nickel without forming detrimental cracks in the thin shell ceramic casting mold. 10. The method of claim 1, which further includes sintering the thin shell ceramic casting mold prior to said pouring. 11. The method of claim 1, wherein the ceramic casting mold has an interior wall surface with a surface finish within a range of about 0.5 microns to about 10 microns. 12. A method for producing a cast component, comprising: forming a free form fabricated ceramic casting mold with a thin outer wall and at least one casting core formed as a contiguous single structure with the outer wall and having a molten metal receiving cavity disposed between the outer wall and the at least one casting core;pouring a molten metal into the molten metal receiving cavity; andafter the beginning of the pouring, solidifying the molten metal within the molten metal receiving cavity and around the integral casting core by adjusting a heat flow dependent upon a stage of solidification. 13. The method of claim 12, wherein said pouring occurs without any substantial additional mechanical support of the casting mold. 14. The method of claim 12, wherein said forming includes photopolymerization of a ceramic filled resin. 15. The method of claim 12, wherein said forming produces the thin outer wall with a thickness within a range of about 0.020 inches to about 0.080 inches. 16. The method of claim 15, wherein the thin outer wall can withstand the molten metal pressure in said pouring without creating detrimental cracks in the thin outer wall. 17. The method of claim 16, wherein the molten metal pressure is within a range of about three to about twenty-four inches of nickel; and wherein the thin outer wall has a thickness less than about 0.060 inches. 18. The method of claim 12, wherein the outer wall has an interior surface adapted to define an internal surface on the cast component, and wherein the casting core is adapted to define internal features within the cast component. 19. The method of claim 18, wherein the ceramic casting mold has an interior wall surface with a surface finish within a range of about 0.5 microns to about 10 microns. 20. A method for producing a cast component, comprising: forming a free form fabricated ceramic casting mold with a thin outer wall and at least one casting core formed as a continuous single structure with the outer wall and having a molten metal receiving cavity disposed between the outer wall and the at least one casting core;pouring a molten metal into the thin shell ceramic casting mold; andmoving a thermal gradient through the molten metal within the thin shell ceramic casting mold to cause solidification into a cast component with a single crystal or directionally solidified microstructure such that the moving includes imparting a first gradient during nucleation and imparting a second gradient higher than the first gradient during growth of a crystal, the moving created by flowing a fluid through a conduit in thermal conductivity with the molten metal.
