Background technique

The motor magnetic ring is an important component of the motor, mainly used to provide a magnetic field to drive the motor to rotate. The stability of the magnetic ring is crucial to the stable operation of the motor. If the magnetic ring is unstable, it will cause problems such as motor vibration and noise. Therefore, the production of motor magnetic rings is to meet the motor's needs for high performance, high efficiency and stable operation. At the same time, with the development of science and technology, the requirements for motor magnetic rings are getting higher and higher, so the production of high-quality motor magnetic rings is also a need for current scientific and technological development.

The motor magnetic ring production mainly adopts the following methods: cutting method, hot pressing method, turntable pressing method and injection molding. Injection molding achieves the shape and size of the product by precisely controlling the material injection and molding process, so it can ensure the high precision of the magnetic ring, and at the same time the uniformity and stability of the material also need to be guaranteed, and it can also realize automated production and improve production efficiency.

The upper end of the injection device 2 is provided with a hopper 5, and the upper end of the hopper 5 is provided with a screening device, which is connected to the machine body 1 through a connecting frame 6. Therefore, the material can be screened before feeding the injection device 2, which can ensure the quality and purity of the raw materials, improve the quality and performance of the product, and also improve the production efficiency and reduce the production cost.

The raw materials can be screened by the screening net 11 to ensure the particle size of the raw materials, which is conducive to injection molding and ensures the stability of the magnetic properties of the motor magnetic ring of the injection molding. At the same time, the unsuitable raw materials can be cleaned by sliding the screening net 11. The side wall of the housing 7 is connected to a vibration motor 12, which is arranged at the feed port 9. It is convenient to screen the raw materials and avoid the blockage of the raw materials.
