Polishing device for automobile part mold

The polishing device comprises an outer frame mechanism, an upper-layer adjusting mechanism, an angle adjusting mechanism, a fixing structure and a lower-layer adjusting mechanism, the upper-layer adjusting mechanism is fixedly installed at the center of the top of the outer frame mechanism, and the angle adjusting mechanism is fixedly installed at the bottom of the upper-layer adjusting mechanism; according to different angles of the inner cavity of the die, the extension lengths of the upper angle adjusting ball joint and the lower angle adjusting ball joint are adjusted respectively to enable the angle adjusting baffle to form an angle attached to the inner cavity of the die, so that the die can be more precisely attached to the grinding head in the polishing process, and the polishing precision of the inner cavity of the die is more accurate; and meanwhile, according to different inner cavity walls, the angles conforming to the inner cavity walls can be formed by adjusting the lengths of the upper angle a
