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 seat armrest bracket. Background Technology

[0002] Magnesium alloys are among the most widely used and best-suited for die casting in the automotive industry. They are lightweight, have good thermal conductivity, strong electromagnetic shielding capabilities, and are easily recyclable, making them a promising "green material" for the 21st century. Currently, they are widely used in automotive electronics, aerospace, and communications industries. Magnesium has a low density and is easily combustible, due to its physical and chemical properties. At 20°C, the density of metallic magnesium is 1.738 g / cm³, and the density of liquid magnesium is 1.58 g / cm³. Under standard atmospheric pressure, the melting point of metallic magnesium is (650±1)°C, and its boiling point is 1090°C. The melting point of magnesium alloys varies depending on the alloy composition, typically ranging from 400°C to 630°C (752°F to 1166°F), depending on the alloying elements and their content. When heated in air, metallic magnesium begins to burn at 632°C to 635°C. Therefore, the preparation and alloy smelting processes of magnesium are relatively complex. Magnesium and magnesium alloys have strong chemical properties, making them easily oxidized and flammable in air, and the resulting oxide film is porous. In contrast, aluminum and aluminum alloys are less flammable because they have an outer layer of aluminum oxide that isolates them from the air. The application of a magnesium alloy seat armrest bracket in automotive applications replaces steel, demonstrating the superiority of magnesium alloys in terms of weight, shock absorption, and driving range.
