Definitions

  • the invention relates to a mold and a method for the production of a lost-foam casting model for a light metal cylinder liner of internal combustion engines.
  • the invention occupies itself with the problem of producing a light metal cylinder liner having a structured surface, in simple manner. This problem is solved in that the mold for the production of the lost-foam casting model of a cylinder liner has a structured surface with height variations of 0.8 to 5 mm, at least in partial regions.
  • Advantageous further developments are the object of the dependent claims.
  • the lost-foam casting model consists of polystyrene.
  • the height variations on the surface of the cylinder liner that form the structured surface amount to 0.8 to 5 mm, preferably 1 to 3 mm, and particularly preferably 1 to 2 mm.
  • the height variations can be formed either by grooves or by elevations, and the grooves or elevations can run preferably in the axial direction, in the circumference direction, or in a diagonal direction. Furthermore, grooves and elevations can also extend in wave shape. Combinations of the stated progressions are also possible.
  • the grooves can be made in the mold for the production of the lost-foam casting model by means of milling, for example; the elevations can be applied by means of application welding.
  • the erosion method is also a possibility.
  • the mold for the production of the lost-foam casting model must be parted in such a manner that the lost-foam casting model can be reliably unmolded. It can particularly be divided into two mold halves or four mold parts.
  • FIG. 1 shows a surface, according to the invention, of a mold for the production of a lost-foam casting model.
  • the surface shows diagonally running grooves 1 .
  • elevations can also be formed instead of the grooves.
  • the surface is divided into diamond-shaped individual areas 2 by the grooves 1 .
