[0029] Working Principle: In the operation of the high-pressure aluminum piston extrusion forming device, the workpiece to be stamped is first placed in the bottom die 5. Then, the stamping rod 13 drives the lifting seat 14 downwards. The lifting seat 14 then simultaneously drives the limiting frame 2 and the top die 21 downwards. The lower die assembly then moves downwards synchronously under its own weight. When the first limiting rod 32 reaches the bottom of the limiting groove 31, it is stopped by the limiting groove 31 and cannot move further. The limiting frame 2 then continues to move downwards, driving the top die 21 downwards to stamp the workpiece. The bottom die 5 is also subjected to pressure and moves downwards, simultaneously compressing the spring 43, causing the bottom die 5, the third slide 51, and the workpiece to move downwards simultaneously. The stamping process then completes the process. Seat 4 provides limiting support for the second limiting rod 46, preventing it from moving downwards and providing a stress point for the workpiece to complete the stamping. Then, the stamping rod 13 drives the lifting seat 14 to move upwards, simultaneously driving the limiting frame 2 and the top mold 21 to move upwards. The limiting frame 2 drives the stamping seat 4 to move upwards as a whole. Then, when the first limiting rod 32 moves to the top of the limiting groove 31, it is limited, thereby supporting the top rod 52 through the limiting frame 2, pushing the workpiece out of the bottom mold 5. Then, the spring 43 pushes the limiting ring 44 upwards with the bottom end of the second sliding groove 42 as the stress point, and the limiting ring 44 simultaneously drives the support rod 45, the second limiting rod 46, and the bottom mold 5 to move upwards, thereby raising the workpiece for easy removal.
