Definitions

  • the present invention relates to a casting chamber for a die casting machine, the cylindrical inner surface serves as a sliding surface for a pressure piston, wherein in Casting chamber jacket over its entire length or over part of the sliding surface for the inner jacket having the pressure piston is used interchangeably, which Inner jacket is pressed against the casting chamber jacket by means of a pressing device and where the casting chamber jacket and inner jacket with a feed opening for liquid Casting material are provided
  • Giesskammem are known and have an oil or water cooling device so that excess heat introduced by the liquid casting material is carried away and the Casting chamber can be kept at a constant operating temperature, so that the Thermal deformation of the casting chamber remains as low as possible.
  • DE 44 21 598 a casting chamber, in which one Half-shell with feed opening for various uses of the casting machine is interchangeably arranged on the casting machine.
  • an exchangeable ceramic insert is arranged in the area of the casting chamber opposite the feed opening, where the largest Wear occurs.
  • the invention now has the task of creating a casting chamber in which no oil or Water cooling device is necessary without the risk of heat deformation increases. Furthermore, should the sliding surface for the pressure piston not wear out whole casting chamber must be replaced. There should also be the possibility with to pour higher casting chamber temperatures.
  • the task is carried out with a casting chamber of the type mentioned solved according to the invention in that the pressing device has a conical wedge and Has screws, the conical wedge in a conical slot of the inner shell is inserted and of the screws screwed into its threaded holes is pressed together with the inner jacket on the casting chamber jacket.
  • the inner jacket is inserted over the entire length, the heat is distributed evenly Over the whole length. It is possible, however, to do this over a partial length inserted inner jacket is sufficient.
  • a good contact is made by means of the pressing device reached between the inner jacket and the casting chamber jacket made of steel, so that the heat in
  • the latter is forwarded.
  • the pressing device it is also conceivable to use the pressing device as Form shrinking device, but the interchangeability of the inner jacket is much easier by loosening the screws screwed into the wedge. So that Heat is also distributed evenly over the inner circumference of the jacket, this has grooves in which there are also rings made of copper with a conical slot, Copper alloy or any other highly thermally conductive material are used. If the inner jacket is made of hot-work steel, it ensures together with the used Rings for even heat distribution over length and circumference. If for the Piston sliding surface a ceramic layer is used, the heat flow can be counteracted be reduced outside.
  • the inner jacket is made of a highly heat-resistant Special alloy with high nickel content, is advantageous on the outer circumference Insulating layer attached, so that because of the significantly higher thermal conductivity than at Steel can be cast with higher casting chamber temperatures. So that Piston sliding surface forms a unit, the conical wedge advantageously consists of same material as the inner jacket.
  • FIG. 1 An exemplary embodiment of a casting chamber according to the invention is described below the only drawing figure explained.
  • the figure shows a perspective View of the casting chamber, the part of the chamber with the casting chamber shield is connected, a quarter is cut away for a better overview, in the chamber part the unchanged view is shown, however, which is connected to the form plate.
  • the casting chamber 1 consists of a cylindrical casting chamber jacket 2 made of steel, in which an inner jacket 3 made of hot-work steel is used, the cylindrical Inner surface forms a sliding surface 4 for the pressure piston.
  • Casting chamber jacket 2 and Inner jacket 3 have a feed opening 5 for liquid casting material.
  • the inner jacket 3 is provided with a conical slot 6, in which one with six threaded holes 7 provided conical wedge 8 is used.
  • Six Allen screws 9 are in corresponding Bores 10 of the casting chamber shell 2 sunk and into the threaded holes 7 screwed so that the conical wedge 8 and through this also the inner jacket 3 against the casting chamber jacket 2 is pressed.
  • the inner jacket 3 has its length uniformly distributed grooves 11, in which also a conical slot 12 having rings 13 made of copper, copper alloy or another highly thermally conductive material are used for example by brazing.
