Definitions
- the invention relates to a method for producing a light metal liner with an outer rough surface for an internal combustion engine.
- a method for producing a light metal liner with an outer rough surface for an internal combustion engine is known from DE 19958185.
- the rough surface of the light metal bushing is created when the bushing is cast in the lost-foa process, in that the foam casting model of the bushing has an outer particle layer with undercuts, which leads to a correspondingly undercut shape of the outer surface of the cast bushing.
- the rough surface of the liner is a prerequisite for a good connection between the liner and the encapsulation material when casting the engine block.
- the invention is concerned with the problem of enabling the production of a liner with an outer rough surface also in permanent mold or sand casting.
- Fixation of the particles is understood to mean that the particles at least do not detach from the casting mold as a result of gravity or float when the melt is poured in.
- the fixation is only possible if possible weak to choose that the partially cast particles detach easily from the surface of the casting mold, in particular a mold or a sheet metal insert for a mold, when the light metal sleeve is formed.
- the particles are particularly preferably fixed in the casting mold by means of core binders which are usually used in the production of sand cores or sand molds.
- Sand molds or inserts made of sand, and also divided sand molds, can also be used as the casting mold.
- a particle size of the particles in a range from 0.3 mm to 1.5 mm leads to an increase in the specific surface area, which is created by many small undercuts from the particle mixture.
- the rough surface does not necessarily have to be present over the entire surface of the liner, but can be restricted to partial areas.
- the largest diameter of the liner is determined in the rough area by the inner diameter of the mold or the mold insert to which the particles are applied.
- Each particle is imaged with respect to the outer diameter of the liner as a depression or as a location of smaller diameter during casting. Since the particles are accessible from the outer diameter after the liner has been formed, they can be dissolved in a liquid or mechanically z. B. can be removed by sandblasting from the liner. Instead of the dissolved particles, depressions remain on the outer diameter of the liner blank.
- the particles advantageously consist of salt, as is also known from the production of salt cores for cooling channels.
- Fig. 1 is a liner with a rough surface in the upper area.
- the upper bushing has a jagged surface on the upper approx. 60% of its length, which is caused by partially cast and later released salt particles.
- the liner is comparatively smooth.
