IPC: H01F41/02
Filed: 1987-05-02
Abstract: PURPOSE:To concentrate the internal stress, generated when temperature goes down after sintering, only at the specific places which become asymmetrical against the center axis, and to prevent the generation of microcracks on other parts by a method wherein a groove is formed at two places in the axial direction on the inner circumferential surface of a cylindrical ferrite molded body. CONSTITUTION:A mandrel 10, on which a protrusion 14 is provided at two places having the angle of 90 deg.-175 deg. against the center axis with each other on one end of the mandrel 10, namely, the end part where a cylindrical molded body 12 will be slided and released from mold in the axial direction (the direction shown by the arrow F in the diagram), is used. By providing the protrusion 14 at two places as above-mentioned, two V-grooves 16 are formed in axial direction on the inner circumferential surface of a mold-released cylindrical molded body 12. Consequently, as the large internal stress generated when a sintering treatment is conducted is concentrated at the part of the grooves 16, the generation of microcracks on the other places can be prevented, and the molded body is divided into two parts at the position of the grooves 16 without fail. Accordingly, internal stress disappears, and no internal distortion is left.
