Definitions
- the invention relates to a mold and a method for producing a lost foam cast model for a light metal liner of internal combustion engines.
- a lost mold more precisely a foam casting model, with a structured outer surface, by adhesively applying particles to the smooth surface of a lost mold, which produce undercuts when the light metal bushing is cast.
- the invention deals with the problem of producing a light metal liner with a structured surface in a simple manner.
- This problem is solved in that the mold for producing the lost foam cast model of a cylinder liner has a structured surface with height differences of 0.8 to 5 mm at least on partial surfaces.
- Advantageous further developments are the subject of the subclaims.
- a structured outer surface is created on the model.
- the model is later embedded in casting sand and connected to the melt via a sprue.
- the model is replaced by the melt.
- the surface structure of the model is shown on the casting, a cylinder liner with a structured surface is created without any additional processing being necessary.
- the foam model is usually made of polystyrene.
- the height differences on the surface of the liner forming the structured surface are 0.8 to 5 mm, preferably 1 to 3 mm and particularly preferably 1 to 2 mm.
- the differences in height can be determined either by grooves or be formed by elevations and the grooves or elevations can preferably run in the axial direction, in the circumferential direction or in the diagonal direction. Furthermore, grooves or elevations can also extend in a wave shape. Combinations of the courses described are also possible.
- the grooves can be introduced into the mold for producing the foam cast model, for example by milling, the elevations by cladding.
- the eroding process can also be considered.
- the mold for producing the foam casting model must be divided so that the moldability of the foam casting model is guaranteed. In particular, it can be divided into two mold halves or four mold parts.
- the surface 1 shows an inventive surface of a mold for the production of a foam casting model.
- the surface shows diagonally extending grooves 1. However, elevations can also be formed instead of the grooves.
- the surface is divided into diamond-shaped individual surfaces 2 by the grooves 1.
