Description

Technical Field

[0001] This utility model relates to the field of magnesium alloy casting technology, and in particular to a casting device for a magnesium alloy head-up display bracket for new energy vehicles. Background Technology

[0002] Magnesium alloys are lightweight engineering metals currently used in engineering applications. They possess advantages such as low specific gravity, good thermal conductivity, strong electromagnetic shielding capabilities, and ease of recycling, and are considered "green materials" with great development and application potential in the 21st century. They are already widely used in industries such as automotive electronics, aerospace, and communications. Magnesium has a low density and is easily combustible, determined by its physical and chemical properties. At 20℃, the density of metallic magnesium is 1.738 g / cm³, and the density of liquid metallic magnesium is 1.58 g / cm³. Under standard atmospheric pressure, the melting point of metallic magnesium is (650±1)℃, and its boiling point is 1090℃. The melting point of magnesium alloys varies depending on the alloy composition, typically ranging from 400℃ to 630℃ (752°F to 1166°F), depending on the alloying elements and their content. When heated in air, metallic magnesium begins to burn at 632℃ to 635℃. Therefore, the preparation and alloy smelting processes of magnesium are relatively complex. Magnesium and magnesium alloys have strong chemical properties and are easily oxidized and combustible in air, and the resulting oxide film is porous. In contrast, aluminum and aluminum alloys are not easily combustible because they have an outer layer of aluminum oxide that isolates them from the air.

[0003] Therefore, modifying the manufacture of new energy vehicles or traditional vehicle parts to use magnesium alloys requires overcoming numerous problems, including magnesium molten metal splashing.

[0004] This utility model proposes a casting device for a magnesium alloy head-up display bracket for new energy vehicles, which is used to manufacture Hongqi HUD. Utility Model Content

[0035] The embodiments of the present invention will be described in more detail below through examples. It should be noted that the embodiments of the present invention are not limited to these examples.

[0036] In one specific embodiment, such as Figure 1 As shown, a casting device for a magnesium alloy head-up display bracket for new energy vehicles includes a body 1, a barrel 2, a first flow channel 3, a second flow channel 4, a third flow channel 5, several slag bags 7 and an exhaust system 8; it also includes a bridging device 6.

[0037] The material cylinder 2 is connected to the first flow channel 3, the second flow channel 4, and the third flow channel 5;

[0038] The first end of the first flow channel 3 is connected to the material cylinder 2, and the second end is connected to the lower first end of the body 1;

[0039] The first end of the second flow channel 4 is connected to the material cylinder 2, and the second end is connected to the lower middle part of the body 1;

[0040] The first end of the third flow channel 5 is connected to the material cylinder 2, and the second end is connected to the lower second end of the body 1;

[0041] The exhaust system 8 is connected to the main body 1, and several slag bags 7 are set at the connection between the exhaust system 8 and the main body 1;

[0042] The first end of the bridge 6 is connected to the first end on the upper side of the main body 1, and the second end is connected to the second end on the upper side of the main body 1.

[0043] In this embodiment, the exhaust system 8 includes an exhaust plate and an exhaust duct. The exhaust duct is connected to the edge of the main body, and the exhaust plate is connected to the exhaust duct. The slag bag 7 is located at the connection between the exhaust duct and the main body.

[0044] In this embodiment, the barrel 2 is used for the inflow of molten magnesium.
