A method for using a mold for processing aluminum parts for automobiles, using the mold for processing aluminum parts for automobiles according to claim 8, characterized in that: The steps include: S1. First, the base (1) is installed in the machine tool by using a plurality of mounting bolts (102); S2. The automobile aluminum part to be cut is placed in the clamping seat (3), and the first cylinder (201) is controlled to operate. The first cylinder (201) controls the pressure in the gas delivery groove (301) to decrease through the first gas delivery channel (202). The multiple clamping mechanisms are operated. The suction force generated by the first cylinder (201) drives the adsorption slide groove (402) to slide on the circumferential surface of the gas delivery pipe (4), so that the L-shaped clamping block (401) in the clamping mechanism slides in the limiting slide groove (305). The L-shaped clamping block (401) contacts the surface of the aluminum part. The multiple L-shaped clamping blocks (401) cooperate to clamp the aluminum part. During the process, the L-shaped clamping block (401) slides until it contacts the surface of the limit block (306), and the L-shaped clamping block (401) squeezes the connecting rod (304) to overcome the elastic force of the return spring (309) in the linkage mechanism, driving the connecting rod (304) and the sliding plate (303) connected to the connecting rod (304) to move, and the sliding plate (303) slides in the adsorption groove (302). At this time, the adsorption hole (501) is connected to the gas delivery groove (301), and the adsorption hole (501) contacts the lower surface of the aluminum part. The aluminum part is adsorbed in the clamping seat (3) through the generated pressure difference, thereby improving the stability of the aluminum part clamping; S3. During the processing of the aluminum part, if the angle of the aluminum part needs to be adjusted, the second cylinder (6) is controlled to operate. The second cylinder (6) controls the operation of the plurality of adjustment mechanisms. The second cylinder (6) controls the lifting rod (605) to move up and down in the sleeve (603) through pressure control. The lifting rod (605) is slidably connected to the connecting seat (604) and drives the lifting of a corner of the clamping seat (3) through the connecting seat (604). The angle of the clamping seat (3) is adjusted, thereby improving the flexibility during the processing of the aluminum part.
