Abstract

An injection molding processing device for an electric machine permanent magnet is disclosed. The device includes a lower mold provided with an injection molding cavity; an upper mold movable up and down relative to the lower mold; an injection molding passage which is disposed on the upper mold and which can communicate with the injection molding cavity after the upper and lower molds are assembled; a material storage chamber used for storing an injection molding raw material and conveying the raw material to the injection molding cavity through the injection molding passage; an impurity filtering device used for filtering the material conveyed from the material storage chamber to the injection molding cavity to remove impurities from the raw material; and a turbulence device used for stirring the raw material after impurity removing through filtration to allow the raw material to be in a turbulence state. The impurities in the raw material are effectively removed through the impurityfiltering device, thus ensuring good performance of a magnet obtained by injection molding, and through the turbulence device, the raw material achieves good homogenizing effect so that the magnet ishigh in stability and not liable to loss of filed.

Description

technical field [0001] The invention belongs to the technical field of motor production and processing, and in particular relates to an injection molding processing device for permanent magnets of a motor. Background technique [0002] In order to solve the problems in the prior art that the permanent magnets in the motor are generally processed by sintering, casting, etc., the degree of shape change is small, the precision is low, the stability is poor, and the magnetism is easy to lose. This kind of magnet can achieve a large degree of shape change and high precision during processing. Traditional injection molding usually directly plasticizes the raw materials through a screw injection molding machine, and then injects them into an injection mold for injection molding. However, since the raw materials are easily doped with impurities, the performance of the injection-molded magnet will be affected, the stability of the magnet will be reduced, and the magnetic strength of...
