Filed: 2021-05-26
Abstract: The present invention relates to a die casting carrier diff manufacturing method, which performs high-vacuum die casting in a state in which an insert ring (10) fabricated by means of normal die casting is coupled to a carrier diff mold (1). After the high-vacuum die casting, the insert ring (10) is removed to be fabricated in a carrier diff (30) of a reverse taper cross-sectional structure. Therefore, the two methods of the normal die casting and the high-vacuum die casting may be applied for the fabrication of the carrier diff, such that the carrier diff may be fabricated also by means of the high-vacuum die casting. In particular, the carrier diff may be fabricated by means of the high-vacuum die casting by the combination of the mold and the insert ring fabricated by the normal die casting. Consequently, the finishing process may be reduced or eliminated, such that the processed amount of the die casting may be significantly reduced, thereby reducing construction costs.
