[0043] Working principle: The material feeding pipe assembly transports the material from the inside of the compression mold 9, and the powder falls into the inside of the magnetic ring outer mold 303 through the opening at the bottom of the compression mold 9. During the process of the four compression molds 9 falling down driven by the hydraulic machine 4, the bottom of the compression mold 9 first contacts the magnetic powder in the inside of the magnetic ring outer mold 303. After the compression mold 9 stops advancing downward, the delay inner rod 905 in the inside of the compression mold 9 will continue to advance downward for a distance until the conical head 906 at the bottom of the delay inner rod 905 is inserted into the conical groove 901, and the bottom of the compression mold 9 will form the entire end face.
