A third through hole is opened in the middle of one side of the movable part 11. The outer diameter of the support rod 9 is smaller than the inner diameter of the third through hole. The support rod 9 and the third through hole are adapted to each other. A movable connecting rod 12 is movably installed at the bottom of the movable part 11, and a connecting seat 13 is welded to the bottom end of the movable connecting rod 12.

A mold forming mechanism is also provided on the upper surface of the processing table 1 for processing and shaping parts.

[0020] By starting the cylinder 15, the connecting plate 14 is pushed to move upward along the inside of the processing table 1, so that the connecting plate 14 moves and drives multiple movable connecting rods 12 to rotate, so that the rotating movable connecting rods 12 push the movable parts 11 to move along the outer surface of the support rod 9, so that the movable parts 11 drive the spring 10 to compress, and the spring 10 buffers and supports the movable movable parts 11, thereby reducing the overall impact force of the upward movement of the connecting plate 14 on the movable plate 6, and then the movable plate 6 slowly moves upward along the outer surface of the fixed rod 5, so that the movable plate 6 pushes the ejector rod 7 to rise synchronously, and the ejector rod 7 passes through the processing table 1 and is inserted into the molding groove 4 to eject the parts, which reflects the buffering effect of the movable plate 6 and the spring 10 on the impact force of the cylinder 15.
