With the development and improvement of material technology and casting forming technology, in order to realize the lightening of new energy vehicles, more and more automobile manufacturers use aluminum alloy castings as assembly parts of new energy vehicles.

[0003] In the existing process, waste aluminum is usually used to prepare recycled aluminum, and the recycled aluminum is used to prepare aluminum alloy castings as assembly parts of new energy vehicles. In the existing process, the main treatment method of waste aluminum for preparing recycled aluminum is smelting, that is, the waste aluminum is heated to above the melting point by a metal smelting furnace, so that the waste aluminum is melted and the aluminum therein is recovered.

[0004] At present, after the melting of waste aluminum is completed by using the smelting furnace, the smelting furnace is usually tilted by using a driving device, so that the aluminum liquid in the smelting furnace is injected into a mold by pouring. However, the nozzle of the existing smelting furnace is usually integrally formed with the furnace body, so that the position of the nozzle will change with the tilting of the smelting furnace during the tilting process, which will cause the nozzle of the smelting furnace to be difficult to align with the material receiving port of the mold, and thus the aluminum liquid will be spilled, which will easily affect the discharging effect of the aluminum liquid.
