CALIPER BODY FOR DISC BRAKES, CASTING MOULD FOR ITS MANUFACTURE, AND METHOD OF MANUFACTURING CALIPER BODY FOR DISC BRAKE USING ITS CASTING MOULD

摘要

PROBLEM TO BE SOLVED: To provide a caliper body for disc brake which can reduce manufacturing cost in such a way that a core is miniaturized and simplified by placing a mould parting position between a drag and the core in back riding a rotor of the caliper body in the inner peripheral side of the back.;SOLUTION: The caliper body is characterized in that a mould parting position 16 being a jointing portion between a drag 11 and a core 13 which constitute a casting mould 10 of the caliper body is positioned corresponding to a position being an inner side face of the back striding the rotor of the caliper body cast/molded in regions A and A, in that casting burr is formed in such a way that metal molten bath invades into the mould parting position 16 when molten metal is poured into a cavity 14, in that this casting burr can be removed in connection with body processing processed by a rotor width milling cutter, in that a manufacturing cost of the caliper body can be reduced without arranging the exclusive removing process for removing the casting burr, and in that the core 13 becomes narrow in its width, and is miniaturized and simplified.;COPYRIGHT: (C)2009,JPO&INPIT
