Injection molding machine intended for the manufacture of injected permanent magnet and method of manufacturing an injected permanent magnet

An injection molding machine intended for the manufacture of injected magnet, comprising:

• a mold consisting of two portions, respectively a first portion and a second portion, disposed facing each other, the first portion being movable in translation relative to the second portion between a first position, corresponding to an open configuration of the mold, and a second position, corresponding to a closed configuration of the mold, said first and second portions being configured to form an internal cavity inside the mold when the latter is in its closed configuration, in which the mold is provided with a first through opening emerging onto the internal cavity, said first through opening allowing the introduction of a molding material inside the internal cavity, and
• in which the mold is provided with a second through opening emerging onto the internal cavity, said second through opening allowing the introduction of at least one shape pin inside the internal cavity;
• a magnetization device capable of applying at least one magnetic field inside the internal cavity of the mold;
• at least one shape pin movable in translation relative to the mold between a first position, called inactive position, in which it is entirely positioned outside the mold, and a second position, called active position, in which it is positioned inside the internal cavity of the mold;
• a demagnetization device capable of removing any magnetization from said at least one shape pin.
