[0020] like Figure 1 to Figure 2 As shown, the powder pressing assembly on the magnetic powder forming press includes a lifting rod 1 and a die 2. The die 2 is placed below the lifting rod 1. A guide rod 10 is installed on the bottom surface of the lifting rod 1. An external thread is installed on the outer wall of the guide rod 10. An annular tube 11 is installed on the top surface of the die 2. A socket is opened in the annular tube 11. An internal thread spirally connected to the external thread is installed on the inner wall of the socket.

[0021] The die 2 is rotated, the internal and external threads are spirally rotated, and the guide rod 10 is rotated out of the socket, so that the die 2 and the lifting rod 1 are separated, and the die 2 can be cleaned. After cleaning, the guide rod 10 is inserted into the blind hole 8 to rotate the die 2, and the die 2 and the guide rod 10 are spirally fixed, thereby achieving the fixation of the die 2 and the lifting rod 1.

[0022] Storage grooves 3 are provided on both sides of the die 2, and extension plates 4 are installed in the storage grooves 3. Pull rings fixedly connected to the extension plates 4 and locking plates 5 movably connected to the extension plates 4 are installed on the extension plates 4, so that the extension plates 4 are placed in the storage grooves 3 and the locking plates 5 are connected to the die 2.

[0023] A supporting plate 6 fixedly connected to the extension plate 4 is installed on the bottom surface of the extension plate 4, and the pull ring is placed between the locking plate 5 and the supporting plate 6. One side of the supporting plate 6 is in contact with one side of the die 2. The bottom surface of the supporting plate 6 is in the same plane as the bottom surface of the supporting plate 6, and the width of the bottom surface of the supporting plate 6 is the same as the width of the bottom surface of the die 2.

[0024] A positioning hole is provided on the extension plate 4, and a rotating shaft 7 is installed in the positioning hole. Both ends of the rotating shaft 7 are connected to the inner wall of the positioning hole. The locking plate 5 is sleeved on the rotating shaft 7 and is rotatably connected to the rotating shaft 7. A blind hole 8 is provided on the locking plate 5. A clamping block 9 is installed on the die 2. The clamping block 9 is elastic and is placed in the blind hole 8 and is clamped and fixed with the blind hole 8.

[0025] Working principle: The bottom surface of the die 2 is used to press the magnetic powder. When the magnetic powder is to be pressed into a long shape, the extension plate 4 is extended into the storage slot 3. When the extension plate 4 is completely in the storage slot 3, the locking plate 5 rotates around the rotating shaft 7, and the blind hole 8 on the locking plate 5 is aligned with the clamping block 9 and pressed to fix the locking plate 5 to the die 2, thereby achieving a fixed state between the extension plate 4 and the die 2. Because the bottom surface of the supporting plate and the bottom surface of the die 2 are on the same plane, the magnetic powder is pressed by the length of the supporting plate 6 and the bottom surface of the die 2, and the length of the pressed magnetic powder can be adjusted.

[0026] When the length of one supporting plate 6 and the die 2 is not enough, since extension plates 4 are installed on both sides of the die 2, the extension plates 4 on both sides are connected to the die 2, and then the length of the pressed molding becomes the length of two supporting plates 6 and the die 2.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
