PROBLEM TO BE SOLVED: To provide a mold which can fix a magnet to a mold surface, firmly enough to prevent detachment of the magnet from the mold surface, while preventing damage of the magnet, and allows easy adjustment of the height of the protrusion of the magnet from the mold surface.SOLUTION: A mold 1 has a screw hole 4 in a mold surface partitioning a cavity 3 and includes a magnet 6 and a nearly cylindrical holder 5, and the holder is screwed into the screw hole through a screw part 51 provided in the outer peripheral surface and holds a magnet with an inner peripheral surface. The maximum outside diameter of the holder is greater than the inside diameter of the screw hole. In the peripheral wall of the hole, one of a through hole 54, a notch part 53 extending partially or entirely in the holder in the axial direction and a thin part is provided.SELECTED DRAWING: Figure 3 |
