Definitions
- the invention relates to a method for casting metals under pressure, wherein the metal into a hollow cylinder lined with a ceramic bushing is poured or inserted, which is connected to a mold, and wherein the metal is then pressed into the mold using a piston Furthermore, the invention relates to a device for performing the method.
- DE 38 90 863 C2 describes a device for carrying out the casting process described as a casting tank.
- the ceramic for example made of silicon nitride or sialon Inner cylinder (socket) provided a plurality of cavities. This is supposed to the heat insulation and temperature properties can be improved so that thermally induced deformations of the outer cylinder are avoided and the ceramic inner cylinder is not claimed so that it breaks. An external one Heating of the inner cylinder is not provided.
- DE-OS 20 51 760 a die casting device is described in which the Filling pipe in which the piston is guided, in the longitudinal direction from different There are materials that are adapted to local working conditions. A such a design is complex and leads to problems at the butt joints. A Heating is also not provided here.
- a filling chamber for a die casting machine is known from DE 42 29 338 A1.
- DE 42 29 338 A1 In the main wear zone st in the area of the feed opening for melt an interchangeable insert arranged.
- EP 0 569 511 B1 describes a die casting process in which a Cast body is brought into thixotropic state by induction heating and then is pressed into a mold cavity.
- a mold cavity itself is only that Heating with a resistance heating element or with a heat transfer medium intended.
- U.S. Patent No. 5,579,825 describes a die casting process. where that in block form Present, potted material is heated inductively and electromagnetically is stirred to its friction in the cylindrical, acted upon by the piston Reduce space or create a distance. The wall of this The room itself is not heated, but cooled.
- the object of the invention is a method and an apparatus of the beginning mentioned type with the most trouble-free die casting process and good casting result to propose.
- the above object is related to the method by characterizing part of claim 1 and with respect to the device by the characterizing part of claim 10 solved.
- the socket Due to the inductive heating, the socket itself can be largely homogeneous bring about the casting temperature of the metal and at least during the Piston feeds to the casting temperature of the respective metal, in particular Aluminum alloy or copper alloy.
- the respective local temperature of the The bushing is therefore largely independent of that of the piston Metal in such a way that no essential between the metal and the socket Heat flow takes place. Seen on the length and circumference of the socket, arises no undesirable temperature gradient in this. This results in the socket no temperature stresses.
- This also has the consequence that in, made of metal or Ceramic existing, hollow cylinder, seen on its length and circumference, no Temperature gradient occurs in such a way that a temperature-related deformation of the Hollow cylinder can lead to damage to the socket.
- the socket can also be improved by mechanical Vibrations, especially high-frequency sound waves, preferably Ultrasound waves are applied. That stamped on the socket mechanical vibrations reduce the friction between that of the piston advanced metal and the socket.
- the mold can also be used during the Piston feeds by means of mechanical vibrations, in particular high-frequency sound waves. This will make it even Distribution of the pressurized metal in the usually cooled mold improved.
- the usually metallic mold can also be used with a ceramic one Be lined.
- the metal is inserted into the hollow cylinder by means of a inductive heating brought into a semi-solid state.
- the semi-solid state of the metal in the hollow cylinder can be measured by means of the pressurized piston be and if necessary be adjustable by means of inductive heating.
- the bushing can be made of a ceramic material that attaches itself to the electromagnetic field of an inductor is inductively coupled.
- the bushing made of a particularly wear-resistant ceramic material, For example, silicon nitride, sialon or the like, which do not themselves exist the electromagnetic field is coupled. It is then the socket by means of a Susceptor indirectly heated inductively.
- the susceptor consists of, for example a carbon-containing ceramic that connects to the electromagnetic field of the inductor couples and brings the socket to the desired temperature.
- An advantageous embodiment of the invention is that the ceramic Socket is interchangeable. This ensures that only the Socket, but not the hollow cylinder must be replaced.
- the figure shows schematically a die casting device in section.
- a metallic hollow cylinder 2 is arranged on a carrier 1 as an outer cylinder.
- a ceramic socket 3 is installed coaxially as an inner cylinder.
- the Socket 3 consists, for example, of silicon nitride or sialon.
- a piston 4 slidably guided.
- the hollow cylinder 2 and the bush 3 have a radial inlet opening 5. By this becomes a metal to be cast in the cylinder space 6 of the bushing 3 poured or inserted in the form of a thixotropic block consisting of a solid and a liquid metal portion.
- a cylindrical susceptor 7 is arranged, which a carbon-containing ceramic, which is connected to the electromagnetic field an inductor.
- the susceptor 7 is surrounded by a heat insulation layer 8. Except for Thermal insulation layer 8, inside the hollow cylinder 2 is an inductor 9, which is likewise essentially over the entire feed distance of the piston 4 extends.
- the inductor 9 can be air or water cooled and is not closer to one shown generator connected.
- the inductor 9 surrounds the susceptor 7 or the socket 3 helical. It lies between the socket 3 and the hollow cylinder 2.
- the inductor 9 can then be connected to it helical area 9 'to be designed meandering to the inductive To ensure heating of the socket 3 to very close to the inlet opening 5.
- This meandering inductor area is identified by 9 ''.
- the Inductor areas 9 'and 9' ' can also be constructed separately. Instead of the however, the meandering design could also be at the inlet opening 5 Helical shape of the inductor 9 must be spread accordingly.
- a mold 10 is arranged on the carrier 1 and forms a mold cavity 11. which is connected via a mouthpiece 12 to the cylinder space 6 of the socket 3 stands.
- the mold cavity 11 can be lined with ceramic.
- the piston 4 has at least one piston ring, which is particularly resilient bears on the wall of the ceramic socket 3.
- the piston ring can be out Ceramic, in particular made of zirconium oxide.
- the friction ratios of the metal pressed forward by the piston 4 in the bush 3 can be applied to the socket 3 by means of high-frequency Improve sound waves.
- a corresponding ultrasonic generator can be for example, install in the carrier 1 or the hollow cylinder 2. Also the Exposure to the casting mold 10 by ultrasonic waves can be advantageous to to improve the inflow and distribution of the metal in the mold cavity 11.
- the inductor 9 is switched on. so that the susceptor 7 is heated inductively, causing the socket 3 approximately Casting temperature of the metal poured or inserted into the cylinder space 3 brought. At about this temperature, the socket 3 during the subsequent feed of the piston 4 held. Through the piston feed the metal is pressed through the mouthpiece 12 into the mold cavity 11. Since the Bushing 3 along the length of the piston feed and over its entire circumference heated, their contact with the metal does not lead to premature wear. Since the socket 3 over the feed length thermally compared to Hollow cylinder 2 is insulated, it does not transfer its heat to the hollow cylinder 2. Da the hollow cylinder 2 is separated from the bush 3 in the area of the piston feed. thermal deformations of the hollow cylinder 2 can not stress the socket 3.
- the socket 3 If the socket 3 is worn, it can be easily replaced axially.
- the wearing part is primarily only the bushing 3 and not the hollow cylinder 2.
- the socket 3 can also be replaced together with the susceptor 7 respectively.
- the casting mold is provided with a ceramic lining, then this too can be interchangeable.
