Technical Field

[0001] The utility model relates to the technical field of automobile parts for magnesium alloys, in particular to a casting device for an automobile steering column bracket for magnesium alloys. Background Art

[0002] With the rapid development of China's new energy vehicle industry, more and more automobile manufacturers are using magnesium alloy as a lightweight material in automobiles, aiming to reduce the vehicle's curb weight while ensuring performance, thereby increasing the vehicle's cruising range; according to public data: if the vehicle's weight is reduced by 10%, fuel efficiency can be increased by 6%-8%; for every 100 kg reduction in the vehicle's curb weight, fuel consumption per 100 kilometers can be reduced by 0.3-0.6 liters; if the vehicle's weight is reduced by 1%, fuel consumption can be reduced by 0.7%, and carbon emissions can be reduced by 0.3%. Due to its light weight and excellent mechanical properties, magnesium alloy is one of the best materials for automotive parts. MS11 is a magnesium alloy automotive steering column bracket product. This magnesium alloy product combines the latest technology in development, design, and application. It is also one of the products currently used in domestic autonomous driving technology, laying a solid foundation for the later development of other similar products.

[0003] The utility model improves the existing production mold of MS11, reduces the injection weight, and improves the product quality. Summary of the invention

[0004] In order to solve the above technical problems, the utility model discloses a casting device for a magnesium alloy automobile steering column bracket. The technical solution of the utility model is implemented as follows:

[0005] A casting device for a magnesium alloy automobile steering column bracket comprises a barrel, a left flow channel, a casting body, a slag bag, an exhaust channel and an exhaust plate;

[0006] The left flow channel connects the barrel and the casting body, the exhaust channel connects the casting body and the exhaust plate, and the slag bag is located at the connection between the exhaust channel and the casting body.

[0007] Preferably, the left flow channel has a width of 80 mm to 100 mm and a thickness of 50 mm to 60 mm.

[0008] Preferably, the size of the slag bag is 30mm*20mm*10mm.

[0009] Preferably, the size of the exhaust duct is 5mm*3mm*2mm.

[0010] The utility model cancels the right flow channel of the original mold for producing MS11 products, which not only improves product quality and reduces energy consumption, but also reduces the injection weight by 80 grams. BRIEF DESCRIPTION OF THE DRAWINGS
