Definitions

  • the invention relates to a method for producing cast parts made of light metal.
  • the invention also relates to a device for producing cast parts made of light metal.
  • From the DE 10329014 A1 is a generic method for eliminating deviations in shape of moldings known.
  • the already cooled and deformed component is reheated in a limited area.
  • a heat zone is formed outside the region to be straightened, which is warmer than the area to be straightened.
  • an electrical induction method is preferably used for the local reheating of the heating zone.
  • the contactless heating can be combined with the stretching or compression of the component in a clamping device.
  • This object is achieved by a method for producing cast parts made of light metal in the casting process, wherein immediately after opening the mold, the mold part is cooled specifically at voltage-sensitive areas with a coolant.
  • the casting can be cooled directly after opening the die, that is, even before ejecting the molding.
  • a signal for opening a coolant supply for targeted cooling of the voltage-sensitive areas of the casting is provided, the signal is set immediately after opening the mold halves of the mold.
  • This is also achieved by arranging at least one spray nozzle for the targeted supply of the coolant to the casting mold part on a fixed mold half with a stationary clamping plate of the die casting mold. This is further achieved by disposing the spray nozzle on a peripheral device such as a picking robot or other suitable location.
  • the casting can be cooled as safely as possible and with as little coolant. This is achieved by measuring the amount and / or the temperature of the supplied coolant. This is also achieved in that the coolant is formed as a liquid or gaseous medium. This is further achieved by using water as the liquid coolant.
  • a die casting machine 1 for the production of mold parts 2 made of light metal is shown schematically.
  • the die-casting machine 1 consists essentially of a casting unit 3, a die-casting mold 4 and a mold closing unit 5.
  • the liquid light metal for example an aluminum or magnesium alloy, is conveyed under pressure into the die-casting mold 4 by the casting unit 3.
  • the mold closing unit 5 is used to open and close the die-casting mold 4.
  • a fully automatic die-casting machine 1 is supplemented by various peripheral devices, such as a removal robot 6 or a computer control.
  • the mold closing unit 5 is shown schematically immediately after the casting process and prior to removal of the mold part 2 in the open state.
  • the most important components of the mold closing unit 5 are a fixed platen 8, which receives a fixed mold half 7, and a movable platen 10, on which a movable mold half 9 is mounted.
  • a fixed platen 8 which receives a fixed mold half 7, and a movable platen 10, on which a movable mold half 9 is mounted.
  • 5 guide columns 11 are provided in the mold closing unit.
  • the guide columns 11 are also used to hold the of the Form closing unit 5 generated locking force, which is generated in order to keep the mold halves 7.9 closed.
  • a molded part 2 is shown schematically, which is located in the movable mold half 9 before ejection.
  • the casting 2 may be formed as a Gusstraube, that is several connected by means of a Angusssystems components, or as a component with a complicated geometry.
  • FIG. 2 shows diagrammatically how a spray nozzle 12 for the targeted supply of the coolant is arranged on the fixed mold half 7 in a wall region.
  • the spray nozzle (s) 12 the coolant is selectively supplied to the areas of the casting part 2, which are responsible for the distortion of the molded part 2. In most cases, these are thick-walled areas, which have a higher temperature than the rest of the casting mold part 2 immediately after opening the die-casting mold 4.
  • the spray nozzle (s) 12 can also be arranged on the stationary clamping plate 8 or on the removal robot 6.
  • the spray nozzles 12 can be directed to any desired area of the mold part 2 in the movable mold half 9.
  • the spray nozzle 12 is preferably controlled by a process control computer, not shown here, which controls and controls the casting and demolding process.
  • the spray nozzle 12 is opened as soon as the mold halves 7, 9 of the pressure casting mold 4 are opened.
  • the opening time and the coolant flow rate of the spray nozzle 12 can be adjusted.
  • the coolant amount and the coolant temperature can be adjusted be that the voltage-sensitive areas are cooled specifically from about 400 ° to about 100 ° C.
  • a liquid or gaseous medium for example water, air or inert gas can be used.
  • the delay of the casting part 2 is minimized.
  • a subsequent revision of the mold 4, which is composed of the mold halves 7.9, and which has been carried out so far to keep the delay within limits, can be saved.
  • the mechanical and / or manual straightening of the mold parts 2 after removal from the die-casting machine 1 and the clamping and straightening device required for this purpose are eliminated.
  • a thermal post-treatment, for example, the stress-free annealing, of the casting 2 may be omitted. Even components with large differences in wall thicknesses can be manufactured without distortion or deformation with this modified die casting process.
