Claims

[Scope of utility model registration request]

A molding position where the first coil surrounds the outer periphery of the movable mold attached to the movable mold mounting plate by supporting the first coil against the outer periphery of the movable mold mounting plate via a slide guide, and a metal mold that exposes the movable mold. A first coil moving device is provided that is movable between the mold attaching and detaching position, a first return yoke is attached to the outside of the first coil, and the first coil can be moved to the molding position or the mold attaching and detaching position and stopped. , Molding in which the second coil surrounds the outer periphery of the fixed mold attached to the fixed mold mounting plate by supporting the second coil via a slide guide on the outer periphery of the fixed mold mounting plate facing the movable mold mounting plate. It is movable between the position and the mold removal position that exposes the fixed mold, and a second return yoke is attached to the outside of the second coil, and the second coil can be moved to the molding position or the mold removal position and stopped. A second coil moving device is provided, and during molding when the movable mold and the fixed mold are in close contact, the first coil and the second coil at the molding position, and the first return old and second return yoke are brought into close contact with each other. A magnetic field generating device for a plastic magnet injection molding machine in which magnetic fluxes generated by the first coil and the second coil form a closed loop.
