Definitions
- the present invention relates generally to die casting. More particularly, the present invention relates to the casting of components having internal passages.
- a method for production of a casting incorporating a passage comprising disposing at least one tube in a mold and casting a metal around the tube.
- the metal may be molten or semi-solid metal and comprise aluminum and aluminum alloys.
- the tubes of the invention may also comprise any metal, including, but not limited to, steel, and be crimped or clamped in some embodiments.
- the outer surface of the tubes can be treated prior to casting. Such treatments include spraying the surface with an aluminum composition, shot blasting, and/or metal plating.
- fluids may be passed through the cast-in tubes before, during, and after casting.
- Molds of the present invention may comprise passages that match the direction of the tube through the casting.
- a system for production of a casting incorporating a passage comprising a disposing means that places at least one tube in a mold and a casting means that casts a metal around the tube.
- the metal may be molten or semi-solid metal and comprise aluminum and aluminum alloys.
- the tubes of the invention may also comprise any metal, including, but not limited to, steel, and be crimped or clamped in some embodiments.
- the outer surface of the tubes can be treated prior to casting.
- Such treatments include spraying the surface with an aluminum composition, shot blasting, and/or metal plating.
- fluids may be passed through the cast-in tubes before, during, and after casting. Molds of the present invention may comprise passages that match the direction of the tube through the casting.
- Another embodiment of the invention provides a cast product having at least one tube and metal cast around the tube.
- FIG. 1 is a diagrammatic representation of a tube and mold, designed with passages to hold the tube.
- FIG. 2. is a cross-sectional view taken along the 2—2 in FIG. 1.
- FIG.3 is a diagrammatic representation of an alternate tube design and mold, also designed with a passage to accommodate the tube.
- FIG. 4 is a cross-sectional view taken from the 4-4 in FIG. 3.
- FIG. 5 is a diagrammatic representation of a tube design that crosses over itself.
- FIG.6 is a diagrammatic representation of two tubes that comprise an intersection.
- An embodiment in accordance with the present invention provides a method for the production of castings with incorporated passages, where the castings are from cast metal and where tubes are cast-in with a superheated molten metal to form the passages.
- the cast metal may be any metal including, but not limited to steel, zinc, magnesium, or combinations thereof.
- aluminum and aluminum alloys are cast.
- Aluminum alloys include 357 alloy, 380 alloy, ADC12 alloy, 356.2 alloy, and other aluminum-silicon alloys.
- a variety of presses and die cast methods may be used with the present invention.
- THT presses may be classified as "indexing- type" or "shuttle-type.” Though the indexing press will be detailed in an embodiment below, both types of presses may be used in the instant invention.
- the THT presses such as a 200 Ton Indexing Shot Machine, a 1000 Ton Shuttle Machine, or a 100 Ton Shuttle Machine, in particular, are capable of operating at a higher speed and with a shorter cycle time than previously known die casting presses and which, as a result, produce higher quality parts with reduced porosity.
- the die casting presses are also simpler and less expensive in construction, requiring less maintenance and therefore more convenient to service.
- the casting methods of the present invention need not be limited to die casting methods of molten metal. In fact, in some embodiments, semi-solid metal (SSM) casting may be preferred. SSM casting is defined broadly herein to encompass any casting technique whereby the metal introduced into a die cavity is greater than 20% granular (i.e., solids).
- SSM casting techniques that are known in the art include, but are not limited to, rheocasting and thixocasting.
- SSM casting may be preferred in some embodiments of the present invention because it is performed at lower temperatures where often 20% -70% of the metal is granular and thus in a slurry, rather than liquid state. The cooler temperatures can extend the useful life of the dies. Moreover, the slurry state of the metal reduces turbulence within the metal flow as it is introduced into the die, so as to reduce the incorporation of air and gas into the metal as it is being cast. Thus, porosity and quality control complications are reduced. [0025] In one embodiment, vertical die cast presses are used with SSM casting techniques.
- the indexing time i.e., the delay between indexing between the pour station 80 and transfer station 85
- the indexing time can be used to control the time the molten metal is cooled in the shot sleeve to reach the SSM range. That is, the amount of time the metal spends in the shot sleeve before it is injected into the molds can be regulated or optimized for a desirable microstructure.
- molten metal at a predetermined temperature may be poured into the shot sleeve of shuttle presses, i.e. presses that lack the indexing feature.
- the shear forces present in SSM casting may be more suitable to the present invention in some embodiments over traditional molten metal casting methods. In such an event, larger tubes ranging from about 0.25 inches to about 0.37 inches in outer diameter may be incorporated into the cast-in tube castings than otherwise possible.
- Many metals and alloys known in the art can be used for SSM casting and can be employed with the instant invention.
- aluminum-silicon alloys can be used. By definition, aluminum alloys with up to but less than about 11.7 weight percent Si are defined "hypoeutectic", whereas those with greater than about 11.7 weight percent Si are defined "hypereutectic".
- Tubes that may be cast-in in the present invention may comprise any metal, preferably steel or hydraulic tubing in some embodiments.
- the steel tubes can have a composition with less than about 0.17 weight percent carbon, less than about 0.35 weight percent silicon, less than about 0.04 weight percent sulfur, less than about 0.04 weight percent phosphorus and between about 0.40- 0.80 weight percent manganese.
- the tubes are free from surface defects, blow holes and cracks.
- Tubes of the present invention can be of varying wall thickness. Where deformation of the tube is not desirable, the wall thickness and composition is preferably strong enough to withstand pressures of 6,000 psi to 20,000 psi and more preferably, pressures of 8,000 psi to 12,000 psi. For steel tubes, the corresponding wall thickness may range from about 0.02 inches to about 0.04 inches, but a wider range may also be acceptable. [0030] Referring now to FIGS. 1 and 2 there is shown a die 1 into which a guide 2 has been cut. The guide 2 can be cut to fit the path of a tube 3 which is to be embedded into the metal cast. The tube 3 may of any design or path.
- the tube 3 may have one opening on one face of the mold or cast and then another opening on another face of the mold or cast as shown in FIG. 1.
- tube 3 may have and opening on one face and then be tapered, crimped, or clamped at the other end such that fluids become trapped inside the cast as shown in FIGS. 3 and 4.
- tubes may have paths that cross over (FIG. 5) or intersect (FIG. 6). All such configurations and others are within the scope of the present invention.
- more than one tube may be incorporated into a cast-in tube mold or product. All such tubes should be accounted for in the design of the mold such that guide 2 may be cut into each half of the mold to accommodate the tube or tubes.
- the tubes 3 may optionally be machined at one or more openings 4. For example, threading for screws or bolts may be inserted.
- the outer surface of the tubes may be coated with a thin surface layer to reduce the likelihood of tube movement (such as slipping or rolling) within the cast product. Coatings may include, such as, for example, alumina and aluminum oxide, and may be sprayed on or plated. The thickness of such coating applications will be apparent to one of ordinary skill in the art. Other treatments to the outer surface of the tubes can include shot blasting or grating.
- the tubes are then secondarily located and secured using a reverse passages in the upper half of the mold such that the tube is secured and crimped or clamped in place.
- the metal is be cast is heated in a range from about 10°C to about 15°C above the liquidus temperature (i.e., the semi-solid temperature).
- the semi-solid temperature i.e., the semi-solid temperature
- the melt temperature is then allowed to cool to form a semi-solid slurry before it is finally cast.
- the mold 1 and tube 3 design is such that, optionally, a cooling medium can be passed through the tubing before, during, and/or after the casting process is taking place.
- couplers may be added to the open end of the tube allow for entry of fluids for cooling.
- the couplers could then be removed, machined, or sheared from the final cast product.
- This procedure may enhance internal casting cooling rates and thus, cycle times.
- internal cooling has the potential to improve the metallurgical properties and/or casting integrity of the final cast product.
- improved tube bonding with the cast is possible.
