METHOD FOR TILT CASTING AND TILT CASTING DEVICE

Abstract

A method for the tilt casting of a component from light metal, in particular of an aluminum alloy, uses a tilt casting mold having a mold cavity. The melt is continuously poured directly into the casting run of the tilt casting mold, which forms the sprue of the component, at the beginning of and during the tilting movement of the tilt casting mold, using a casting ladle or a casting scoop, and flows through the casting run into the mold cavity of the tilt casting mold from the beginning, wherein the casting ladle or the casting scoop continuously tracks the casting mold during the tilting movement.

Claims

1: A method for tilt casting of a component composed of light metal, in particular of an aluminum alloy, by means of a tilt casting mold (10) having a mold cavity, wherein the melt is continuously poured directly into the casting run (14) of the tilt casting mold (10), which forms the sprue of the component, at the beginning of and during the tilting movement of the tilt casting mold (10), using a casting ladle or a casting scoop (12), and flows through the casting run (14) into the mold cavity of the tilt casting mold (10) from the beginning, wherein the casting ladle or the casting scoop (12) continuously tracks the casting mold (10) during the tilting movement.

2: The method for tilt casting according to claim 1, characterized in that the tilt casting mold (10) is brought into a pouring position at the beginning of the tilting movement, in which position the melt flows into the mold cavity of the tilt casting mold (10) free of turbulence, to the greatest possible extent, when it is poured into the casting run (14).

3: The method for tilt casting according to claim 1, wherein the tilt casting mold (10) is tilted about a tilting axis by up to 90.

4: The method for tilt casting according to claim 1, wherein the casting ladle or the casting scoop (12) is guided at a distance from the casting run (14).

5: The method for tilt casting according to claim 1, wherein the melt is guided through a bottleneck within the casting run (14).

6: A tilt casting device for carrying out the method according to claim 1, comprising a tilt casting mold (10) that has a mold cavity, into which cavity the melt can be poured by way of a casting run (14), and means for tilting the tilt casting mold (10) from a pouring position into a position tilted by up to 90 relative to the former, wherein the casting device does not have a casting pool or melt holding container, for example in the form of a transverse run, in particular no casting pool or melt holding container connected with the casting run (14) in terms of flow, for example in the form of a transverse run.

7: The tilt casting device according to claim 6, wherein a bottleneck is provided within the casting run (14).

8: The tilt casting device according to claim 6, wherein the casting device has a casting ladle or a casting scoop (12) assigned to it, wherein the melt can be poured into the casting run (14) of the tilt casting mold (10) that forms the sprue of the component, by means of the casting ladle or the casting scoop (12), at the beginning of and during the tilting movement of the tilt casting mold (10), continuously and directly.

Description

[0021] In the following, the invention will be explained using an exemplary embodiment, which is shown in the drawing. In the drawing, the figures show:

[0022] FIG. 1 schematically, a snapshot of casting scoop and casting mold with casting run at the beginning of the tilting movement of the casting mold with casting run,

[0023] FIG. 2 schematically, a snapshot of casting scoop and casting mold with casting run during the tilting movement of the casting mold with casting run, and

[0024] FIG. 3 schematically, a snapshot of the casting mold with casting run at the end of the tilting movement of the casting mold with casting run.

[0025] In the drawing, characteristics that are significant for understanding the invention are shown and explained. If the same reference numbers are used in the figures, these refer to the same parts.

[0026] In the case of the method according to the invention for tilt casting of a component composed of light metal, in particular of an aluminum alloy, by means of a tilt casting mold 10 having a mold cavity, the melt is continuously poured, at the beginning of and during the tilting movement of the tilt casting mold 10, into the casting run 14 of the tilt casting mold 10, which forms the sprue of the component, directly, using a casting scoop 12, wherein the melt flows into the mold cavity of the tilt casting mold 10 through the casting run 14 from the beginning, and the casting scoop 12 continuously tracks the tilt casting mold 10 during the tilting movement.

[0027] As shown in FIG. 1, the tilt casting mold 10 is brought into a pouring position at the beginning of the tilting movement, in which position the melt flows into the mold cavity of the tilt casting mold 10 with low turbulence, to the greatest possible extent, while it is being poured into the casting run 14. The tilt casting mold 10 is then tilted about a tilting axis by 90.

[0028] In this regard, FIG. 2 shows a snapshot of the tilt casting mold 10 tilted by 45, while FIG. 3 shows the end position, preferably the solidification position of the tilt casting mold 10, tilted by 90.

[0029] In this regard, the casting scoop 12 is guided at a distance from the casting run 14, in other words not connected with the mold.
