WIPO Patent Application WO/2019/190086
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing an integral type brake disc and a brake disc manufactured thereby, the method comprising the steps of: preparing an upper mold having a hub cavity formed at the center thereof and a fitting protrusion formed therein, and a lower mold having a core formed therein, a plurality of guide stepped portions formed therein, and a disc accommodating space formed therein; placing a friction disc having gap forming joints protruding at regular intervals along the outer periphery of a through hole in the disc accommodating space so that each of the gap forming joints is in surface contact with the guide stepped portions; inserting arcuate air flow forming portions between the guide stepped portions; and forming a joint so that the fitting protrusion is inserted into an insertion groove formed by the pair of adjacent air flow forming portions and the gap forming joints therebetween, and injecting molten metal of the hub material to be joined to the upper end of the gap forming joints so that the friction disc and the hub are integrally cast.
