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 by means of a tilt casting mold having a mold cavity, wherein the melt is continuously poured directly into a casting run of the tilt casting mold, which forms a sprue of the component, only while the tilt casting mold is in a tilted position 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, wherein the casting ladle or the casting scoop is guided at a distance from the casting run.

2. The method for tilt casting according to claim 1, wherein the tilt casting mold 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 free of turbulence, when it is poured into the casting run.

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

4. The method for tilt casting according to claim 1, wherein the melt is guided through a bottleneck within the casting run.

Description

(1) In the following, the invention will be explained using an exemplary embodiment, which is shown in the drawing. In the drawing, the figures show:

(2) 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,

(3) 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

(4) 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.

(5) 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.

(6) 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.

(7) 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°.

(8) 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°.

(9) 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.
