Gravitational pressurization casting equipment for automobile hub production

Abstract

The invention relates to a gravity pressurized casting equipment for the production of automobile wheel hubs. The vibration mechanism includes a third motor, a driving wheel, a fixed shaft, a frame, a vibrating block and several springs, and the detection mechanism includes an adjustment unit and several detection units. The gravity pressurized casting equipment used for the production of automobile wheels passes The vibration mechanism makes the vibrating block hit the upper mold, through the vibration, the circulation of the molten metal between the upper mold and the lower mold is strengthened, the material is evenly distributed, and the quality of the automobile wheel hub is improved. Not only that, the detection mechanism drives the X-ray searchlight on the upper mold The mold and the lower mold rotate and emit X-rays. By detecting the attenuation of the X-rays, it is determined whether there are bubbles in the molten metal, thereby further ensuring the casting quality of the automobile wheel hub and improving the practicability of the equipment.

Description

technical field [0001] The invention relates to the field of casting equipment, in particular to a gravity pressurized casting equipment used for the production of automobile wheel hubs. Background technique [0002] Automobile hubs, also known as turntables, are parts for installing tires on the hubs. They are divided into steel hubs and aluminum alloy hubs. The automotive hub industry belongs to the auto parts and accessories manufacturing industry. Generally, automotive hubs are manufactured by gravity casting and pressure casting. , where gravity casting refers to the process of pouring molten metal into a metal cavity under the action of gravity on the earth to obtain castings, while the essence of pressure casting is to fill the mold with a liquid or semi-liquid metal state under high pressure, and under pressure A method of forming a casting. [0003] However, whether it is gravity casting or pressure casting, in the casting process of automobile wheels, the circulat...

Problems solved by technology

[0003] However, whether it is gravity casting or pressure casting, in the casting process of automobile wheels, the circulation performance of liquid metal is poor, resulting in uneven metal distribution inside the mold, so after the production is completed, the material distribution of automobile wheels is uneven, not only that, due to the mold In a closed environment, it is difficult for operators to see the distribution of liquid metal in the mold, and they often rely on experience to operate, which leads to rough production, poor precision and high defective rate of formed automobile wheels
