This invention is directed generally to die cast systems, and more particularly to manufacturing methods for turbine airfoils usable in turbine engines.

BACKGROUND

Turbine blade airfoils typically have internal cooling systems formed from a plurality of cooling channels, as shown in Figure 2 and 3. To form these cooling channels inside of a blade, a casting mold is often used and includes an internal ceramic core and external ceramic shell. The ceramic core, as shown in Figure 1, is manufactured to include detail features on the core die surface in order to form efficient cooling devices inside the blade casting. The core dies typically used to form cores are most often formed from hard steel, which are expensive to manufacture. The core die surfaces are typically in direct contact with the ceramic core material during the high pressure injection process. The core die will wear out after sufficient injections and lead to non-conforming casting. To maintain accurate casting dimensions, the core die needs to be reworked or replaced when a core die becomes worn, which is an expensive endeavor. Even a small improvement on an internal surface requires that a completely new die be made. Thus, a need exists for a more robust, less expensive system.

SUMMARY OF THE INVENTION

A die cast system having an inner liner insert that enables the configuration of a component produced by the system to be easily changed by changing the inner liner insert without having to rework the die housing is disclosed. Because the inner liner insert only need be removed and replaced to change the configuration of an outer surface of a component produced by the system, the cost savings is significant in contrast with conventional systems in which the die would have to be reworked. The die cast system may also include an inner liner formed from first and second end sub-inner liners, whereby the first end sub-inner liner may be from a first material that is less compliant than a material forming the second end sub-inner liner enabling more intricate cooling systems to be created by the second end sub-inner liner that is formed from a more compliant material.

In at least one embodiment, the die cast system may include a die housing having one or more inner chambers forming an insert receiving chamber and one or more inner liners positioned within the insert receiving chamber of the inner chamber of the die housing. The inner liner may have an inner surface defining boundaries useful to form an inner surface of a turbine component, whereby the inner liner may be formed via a selective laser melting process. The inner liner may be formed from a first side sub-inner liner forming a first side of the turbine component and a second side sub-inner liner forming a second side of the turbine component. The first side sub-inner liner may form an outer wall of a suction side of an airfoil usable in a gas turbine engine and may include at least one cavity on an inner side of the outer wall that is configured to form at least a portion of an internal airfoil cooling system. The second side sub-inner liner may form an outer wall of a pressure side of an airfoil usable in a gas turbine engine and may include one or more cavities on an inner side of the outer wall that is configured to form at least a portion of an internal airfoil cooling system.

In at least one embodiment, the inner liner may be formed from a non-ceramic, flexible material. The inner liner may be formed from a different material than the die housing. The die housing may be formed from a first sub-die housing and a second sub-die housing having a mateable interface positioned therebetween such that the first and second sub-die housings are mateable at the mateable interface.

In another embodiment, the inner liner may be formed from a first end sub-inner liner forming a first end of the turbine component and a second end sub-inner liner forming a second end of the turbine component. The first end sub-inner liner may be formed from a first material that is less compliant than a material forming the second end sub-inner liner. The second end sub-inner liner being more compliant may be used to form intricate aspects to the internal cooling system. The first end sub-inner liner may be configured to form a leading edge of an airfoil usable in a turbine engine and second end sub-inner liner is configured to form a trailing edge of the airfoil usable in the turbine engine.

In at least one embodiment, the first end sub-inner liner may be formed from a first end, first side sub-inner liner and a first end, second side sub-inner liner. The first end, first side sub-inner liner may form a suction side outer wall of an upstream portion of a suction side of an airfoil usable in a gas turbine engine and may include one or more cavities on an inner side of the suction side outer wall that is configured to form at least a portion of an internal airfoil cooling system. The first end, second side sub-inner liner may form a pressure side outer wall of a pressure side of the upstream portion of an airfoil usable in a gas turbine engine and may include one or more cavities on an inner side of the pressure side outer wall that is configured to form at least a portion of an internal airfoil cooling system.

The second end sub-inner liner may be formed from a second end, first side sub-inner liner and a second end, second side sub-inner liner. The second end, first side sub-inner liner may form a suction side outer wall of a downstream portion of a suction side of an airfoil usable in a gas turbine engine and may include one or more cavities on an inner side of the suction side outer wall that is configured to form at least a portion of an internal airfoil cooling system. The second end, second side sub-inner liner may form a pressure side outer wall of a pressure side of the downstream portion of an airfoil usable in a gas turbine engine and may include one or more cavities on an inner side of the pressure side outer wall that is configured to form at least a portion of an internal airfoil cooling system.

A method of forming a turbine component is disclosed. The method may include injecting a ceramic material into at least one inner cavity formed within a composite die cast system, wherein the die cast system may be formed from a die housing having one or more inner chambers forming an insert receiving chamber and one or more inner liners positioned within the insert receiving chamber of the inner chamber of the die housing. The inner liner may have an inner surface defining boundaries useful to form an inner surface of a turbine component. The inner liner may be formed via a selective laser melting process. The method may also include removing the die cast system thereby revealing a ceramic core.

The method may include firing the ceramic core, placing the ceramic core within an inner cavity formed by an inner surface of a wax die, and injecting wax into one or more openings formed between the ceramic core and the inner surface of the wax die. The method may also include removing the wax die to reveal a wax component, coating the wax component with a ceramic coating to form a ceramic shell with a ceramic core positioned therein and removing the wax component within the ceramic coating leaving one or more cavities within the ceramic coating. The method may also include filling the cavity within the ceramic coating with a molten metal and removing the ceramic shell and the ceramic core to form a cast component.

An advantage of the composite die cast system is that because the inner liner insert only need be removed and replaced to change the configuration of an inner surface of a component produced by the system, a significant cost savings is captured in contrast with conventional systems in which the die would have to be reworked.

Another advantage of the hybrid die cast system is that use of the hybrid die cast system will reduce time and effort required to create a core die in a conventional casting process.

Yet another advantage of the hybrid die cast system is that the inner liner may be formed from different portions formed from different materials, thereby enabling portions of the inner liner proximate to aspects of the core where intricate aspects of an internal cooling system are located, to be formed from more compliant material enabling those intricate aspects of the internal cooling system to be formed.

These and other embodiments are described in more detail below.
