- the Temperature course is e.g. known from DE 195 45 177 A1
- the Workpiece or metal by a time-varying electromagnetic Inductively heat the field. This allows a defined amount of heat be introduced into the workpiece, the local and temporal Distribution of the inductive field can be varied. The change of the electromagnetic field can from the forming state be made dependent on the workpiece.
- GB-A-2160456 discloses a casting method which is not suitable for a die casting operation provided or suitable. Embedded in the mold Electrodes are heated by a current flow and thereby heat the mold and indirectly the metal, especially in storage rooms, from which metal should flow into the work space, if the metal solidifies in the work space and contracts.
- WO-93/22088-A also discloses a casting process that does not involve die casting is and in particular takes place in a sand mold.
- One Electric current is passed through the filled metal and is intended to cause that supply and overflow lines with a small cross-section are usable without the metal in these lines prematurely cures.
- the mold is with connection points for a single Circuit provided.
- the invention is based on the object, an improved die casting process to create with expanded possibilities.
- This object is achieved with a method of the initially mentioned type solved in that on parts of the die-casting device an electrical voltage is applied through the metal closed circuit is made conductive by the metal Heat energy is supplied, and that in individual phases of the die-casting process different power supplies to form different Power flows take place.
- a device for carrying out the Method provided with a die-casting device, which has multiple connection points for applying an electrical voltage, with which an electric current through contained in the die-casting device liquid or pasty metal is istleitbar, and with a control device to change the power supply during different Phases of the die casting process.
- the metal is thus conductively heated, i. H. it will an electric current is passed through the metal.
- the invention a tension on suitable parts of the tools used for this purpose or the primary shaping device placed, between which the metal located.
- Such conductive heating may be opposed to inductive heating be achieved with relatively little expenditure on equipment by a suitable power source to the desired parts of the Device is connected.

- the power supply can be in individual phases of the process done differently.
- a die-casting process can during the filling phase, during which the molten or pasteuse metal is poured into the casting chamber, advantageously a tension between casting piston and anvil be applied so that a current over the length of the casting chamber generated by the metal.
- the temperature of the metal can be constant being held; furthermore, it is possible to change the temperature of the metal in the casting chamber, so that in a melting phase before filling not unnecessarily much Energy is consumed.
- a later heating is in particular in Thixo casting method or SMS (Solid State Melting) method useful in which a slug of a merely softened or pastey metal introduced is, as an unnecessary heating of the Butzens or a Keep warm pre-heated slugs before filling thus at least can be partially prevented.
- During the mold filling can be a tension in particular be placed between the mold halves, so that in the Mold cavity located metal directly between the mold halves is heated.
- electrodes for this purpose, if the mold halves on its inside to a greater extent with a ceramic Insulator are coated, in addition also electrodes be used.
- electrodes for example, also used in the mold halves mounted metallic heat sink so that attaching further electrodes in existing devices is unnecessary.
- a Electricity also between casting piston or casting chamber and a or both mold halves are generated, so that the metal still in the casting chamber and in the gate is heated.
- one or both mold halves or in particular the Casting and / or casting chamber can be used.
- the pressing residue between casting and anvil to keep fluid, thus continuing a pressure exerted on the metal located in the mold cavity is going to make a good compaction or metering of the metal to ensure in the mold cavity.
- a tension between casting piston or casting chamber and the mold halves or one mounted in them Electrode or attached in them slide the Bleed the interior of the casting chamber with the mold cavity connects, be kept free, so that on the Press rest applied pressure a longer time to that in the Mold cavity located metal acts.
- a suitable current flow in the metal can furthermore achieved a directional solidification in the mold cavity first, by working in the areas of lower amperage a cooling occurs from here in the Form cavity continues to migrate. As with a cooling down the Metal releases from the walls of the mold halves, a resistance crack occurs one that enhances this effect. It can thus successively a detachment of the metal in the solidified Areas of the mold halves and a directed Solidification can be achieved.
- After solidification can be another temperature treatment to improve the structure, in which the material in desired Regions in the desired manner conductive heat energy is supplied without further aids.
- conductive heat energy is supplied without further aids.
- the inventive method can for a manual be performed. Furthermore, the voltage or Current profile as a function of calculated or measured Function curves are varied. For this purpose, e.g. a desired startup or shutdown characteristic when increasing and lowering the currents are performed.
- According to the invention is also advantageously a scheme with temperature measurement of the metal, so that the voltage or current as a function of a temperature or the measured in several points of the metal Temperature values can be changed. This allows the Temperature in particular kept constant or a temperature drop delayed of the metal.
- Another measure for a control can be measured. Here, in particular, an in-mold pressure between the mold halves are measured. This measurement can e.g.
- a piezocrystal be provided under an ejector, so that over the slidable ejector pin a measurement of the internal mold pressure is possible.
- an ultrasonic emission of the Metal e.g. in the range of 100 kHZ.
- Such a sound emission analysis may be due to the undesirable Voids formation closed during solidification become.
- An example of such a sound emission analysis is shown in DE 39 40 560 C2.
