Description

Technical Field

[0001] This utility model relates to the field of new energy electric vehicle parts technology, and in particular to a casting device for a magnesium alloy instrument panel 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 instrument panel bracket for new energy vehicles, used in the manufacture of Hongqi CCB. Utility Model Content
