Embodiment Construction

[0037] for manufacturing in figure 1 The cast part 1 depicted in and constructed as a chassis component is made of aluminum or an aluminum alloy through a casting process provided in the figure 2 The casting mold 2 shown in schematic diagram.

[0038] The casting mold 2 configured as an ingot mold has a cavity 4 delimited by a casting surface 3 into which a liquid or flowable metal melt 5 made of aluminum is filled in the casting process, which metal melt In the cavity 4 the movement in the flow direction 6 is then continued. The substantially smooth casting surface 3 has a surface structuring 7 at least in sections. figure 2 A point in time of the casting process is shown at which the melt front 8 of the metal melt 5 has not yet reached the region in which the surface structuring 7 is arranged.

[0039] image 3 based on figure 2 The view of line A-A in shows the figure 2 The surface structuring shown in 7. The surface structure 7 is composed of a plurality of basi...

Abstract

The invention relates to a casting mold (2) which comprises at least one cavity (4) for manufacturing at least one cast article and in which at least some areas of a casting surface (3) of the casting mold (2) delimiting the cavity (4) have a surface structure (7). The surface structure (7) consists of a plurality of elementary cells, each of which has a structure that is raised and / or recessed in relation to the casting surface (3) and ends within the elementary cell. The invention further relates to a cast article manufactured using said casting mold (2).

Description

technical field [0001] The invention relates to a casting mold with at least one cavity for producing at least one casting and the casting produced by means of the casting mold. Background technique [0002] EP 0 106 203 A1 already discloses a thin-walled cast part with rib-shaped elevations or enlargements, wherein the elevations or enlargements form interconnected connecting ribs and limit the number of filling surfaces. In the case of casting, the melt flows from four directions through straight, vertically and horizontally extending ribs into the filling surfaces, so that these filling surfaces are filled quickly. Cold welding can be effectively prevented in this way. The use of this casting is suitable for housings and wheels in the automotive industry. [0003] In the series production of lightweight chassis components made of aluminum alloys, castings with wall thicknesses above 5 mm are only possible here, especially in the case of relatively large flow paths of th...
