範囲第１項記載の金型。[Claims for Utility Model Registration] 1. In a mold for injection molding a ring-shaped resin magnet having radial anisotropy, an inner pole made of a ferromagnetic material is placed inside a space into which resin is press-fitted to form a product. 1, and a cylindrical outer pole made of ferromagnetic material on the outside, respectively.
For injection molding, the inner pole and the outer pole are magnetized by a magnetic field from a separately installed excitation coil member, so that the magnetic field can be applied uniformly and radially in the space. Mold. 2. The mold according to claim 1 of the utility model registration claim, in which the space between the inner pole and the outer pole other than the space that is to become a product is covered with a non-magnetic material.
