は、第4図の金型が全開した状態での断面図。Figure 1 is a sketch of a permanent magnet before gate cutting, which was injection molded using a conventional two-plate mold. FIG. 2 is a cross-sectional view of a mold according to a conventional method for manufacturing the permanent magnet of FIG. A permanent magnet is injected into the black part. Moreover, the white part and the shaded part indicate the magnetic circuit. Figures 3a and 3b are cross-sectional views of the mold shown in Figure 2 when it is opened. FIG. 4 is a cross-sectional view of the same product part as shown in FIG. 1 made using a three-plate mold according to the present invention. FIG. 5 is a cross-sectional view of the mold shown in FIG. 4 in a state in which it is about halfway in place. FIG. 6 is a sectional view of the mold shown in FIG. 4 in a fully opened state.
