Injection molding anisotropic bonded neodymium-iron-boron magnetic shoe radiation orientation forming method and device

The invention provides an injection molding anisotropic bonded neodymium-iron-boron magnetic shoe radiation orientation forming method and an injection molding anisotropic bonded neodymium-iron-boronmagnetic shoe radiation orientation forming device. The device comprises an A-type oriented permanent magnet, a B-type oriented permanent magnet, a C-type oriented permanent magnet, a magnetic flow channel, an inner mold core and a non-magnetic outer mold core, the problems that a conventional built-in permanent magnet orientation field adopted by an anisotropic injection molding neodymium-iron-boron bonded magnet is low, and the orientation degree of a product is not high are solved, the orientation magnetic field in the mold is larger than 1T based on the HALBACH array and combination of permanent magnets of different specifications, and then the injection molding neodymium-iron-boron orientation process is met. On the basis of permanent magnet orientation magnetic circuit combination design, anisotropic injecti
