Description

technical field [0001] The invention relates to the technical field of magnetic materials, in particular to an injection mold and an injection molding method for preparing multi-orientation anisotropic plastic magnets. Background technique [0002] With the development of science, the application of magnets has become more and more extensive, and people have put forward different requirements for the application efficiency of magnets. For example, for magnetic rings or magnetic tiles, people no longer want the magnetic rings or magnetic tiles only in them A certain orientation has higher magnetic performance, but it is hoped that the magnetic ring or magnetic tile has higher magnetic performance in at least two orientations, for example, in both the inner diameter orientation and outer diameter orientation of the magnetic ring or magnetic tile. It has high magnetic performance, that is, multi-orientation anisotropic magnetic ring or multi-orientation anisotropic magnetic til...
