Definitions

  • This disclosure relates generally to casting, and more particularly to die casting system machine configurations.
  • Casting is a known technique used to yield substantially net-shaped components.
  • investment casting is often used in the gas turbine engine industry to manufacture net-shaped components, such as blades and vanes having relatively complex shapes.
  • Investment casting involves pouring molten metal into a ceramic shell having a cavity in the shape of the component to be cast.
  • Investment casting can be relatively labor intensive, time consuming and expensive.
  • Die casting involves injecting molten metal directly into a reusable die to yield a net-shaped component. Die casting has typically been used to produce components that do not require high thermal mechanical performance. For example, die casting is commonly used to produce components made from relatively low melting temperature materials that are not exposed to extreme temperatures. Existing machine configurations for die casting systems have not been effective to cast components made from high temperature alloys.
  • a die casting system includes a die, a shot tube and a shot tube plunger.
  • the die is comprised of a plurality of die components that define a die cavity.
  • the shot tube is in fluid communication with the die cavity and includes an integrated melting unit configured to heat a charge of material from a position inside the shot tube.
  • the shot tube plunger is moveable within the shot tube to communicate the charge of material into the die cavity.
  • a method of die casting a component includes loading a charge of material into a shot tube of a die casting system, heating the charge of material at a position inside the shot tube, and injecting the charge of material into a die cavity of the die casting system to form the component.
  • a die casting system also disclosed includes a die, a shot tube and a shot tube plunger.
  • the die is comprised of a plurality of die components that define a die cavity.
  • the shot tube is in fluid communication with the die cavity.
  • the shot tube plunger is moveable within the shot tube to communicate molten metal into the die cavity.
  • the die casting system is positioned relative to a surface. Each of the die, the shot tube and the shot tube plunger are positioned at an angle relative to the surface during injection of the molten metal into the die cavity.
  • Figure 1 illustrates a die casting system 10 having a machine configuration 11.
  • the die casting system 10 includes a horizontal machine configuration.
  • the die casting system 10 includes a reusable die 12 having a plurality of die elements 14, 16 that function to cast a component 15.
  • two die elements 14, 16 are depicted in Figure 1 , it should be understood that the die 12 could include more or fewer die elements, as well as other parts and configurations.
  • the die 12 is assembled by positioning the die elements 14, 16 together and holding the die elements 14, 16 at a desired positioning via a mechanism 18.
  • the mechanism 18 could include a clamping mechanism of appropriate hydraulic, pneumatic, electromechanical and/or other configurations.
  • the mechanism 18 also separates the die elements 14, 16 subsequent to casting.
  • the die elements 14, 16 define internal surfaces that cooperate to define a die cavity 20.
  • a shot tube 24 is in fluid communication with the die cavity 20 via one or more ports 26 located in the die element 14, the die element 16, or both.

  • the shot tube 24 receives a molten metal from a melting unit 25, such as a crucible, for forming the component 15.
  • a melting unit 25 such as a crucible
  • the molten metal is melted in the melting unit 25 at a location that is separate from the shot tube 24.
  • this disclosure is not limited to melting units located separate from the other die casting system components.
  • Materials capable of being used to diecast a component 15 include, but are not limited to, nickel based super alloys, titanium alloys, high temperature aluminum alloys, copper based alloys, iron alloys, molybdenum, tungsten, niobium or other refractory metals. This disclosure is not limited to the disclosed alloys, and it should be understood that any high melting temperature material may be utilized to cast the component 15. As used herein, the term "high melting temperature material" is intended to include materials having a melting temperature of approximately 1500°F (815°C) and higher.
  • the shot tube 24 receives a sufficient amount of molten material to fill the die cavity 20.
  • the shot tube plunger 28 is actuated to inject the molten metal under pressure from the shot tube 24 into the die cavity 20 to cast the component 15.
  • the die casting system could be configured to cast multiple components in a single shot (see Figures 3 and 4 , for example).
  • the die casting system 10 can be positioned within a vacuum chamber 34 that includes a vacuum source 35.
  • a vacuum is applied in the vacuum chamber 34 via the vacuum source 35 to render a vacuum die casting process.
  • the vacuum chamber 34 provides a non-reactive environment for the die casting system 10 that reduces reaction, contamination, or other conditions that could detrimentally affect the quality of the cast component 15, such as excess porosity of the die cast component that can occur as a result of exposure to oxygen.
  • the vacuum chamber 34 is maintained at a pressure between 1 ⁇ 10 -3 Torr and 1x10 -4 Torr, although other pressures are contemplated.
  • the actual pressure of the vacuum chamber 34 will vary based on the type of component 15 being cast, among other conditions and factors.
  • the melting unit 25, the shot tube 24, and the die 12 are positioned within the vacuum chamber 34 during the die casting process such that the melting, injecting and solidifying of the metal are each performed under vacuum.
  • the vacuum chamber 34 is backfilled with an inert gas, such as Argon, for example.
  • the machine configuration 11 of the die casting system 10 depicted in Figure 1 is illustrative only and could include more or less sections, parts and/or components. This disclosure extends to all forms of die casting, including but not limited to, horizontal systems, vertical systems, vacuum systems, or non-vacuum systems. Described below are additional machine configurations of die casting systems capable of casting components made from high melting temperature materials.
  • the example machine configurations described below and depicted in Figures 2-5 maintain thermal control of the molten metal received by the die casting system components and thereby minimize thermal losses (i.e., heat of the molten metal) during injection.

  • the die 12, the shot tube 24 and the shot tube plunger 28 are each angled relative to the surface 40 at an angle ⁇ .
  • the machine configuration 111 therefore changes the orientation of the die casting system 110 relative to the surface 40 such that the surface area contact between molten metal and the interior of the shot tube 24 is reduced. Reduction of the surface area contact of the molten metal with the shot tube 24 minimizes thermal losses of the molten metal that can occur during injection, and reduces the thermal stresses acting upon the shot tube 24.
