[0031] The demoulding mechanism is composed of a connecting block 19, a connecting rod 20, a ring 21, a rotating shaft 22, a second fixed block 23, and a rotating nut 25;

[0032] The connecting block 19 is fixedly installed at the bottom of the second module 2, one end of the connecting rod 20 is movably installed inside the connecting block 19, the fixed block 23 is fixedly installed on the inner wall of the base 1, the rotating shaft 22 is movably installed on the inner wall of the fixed block 23, the rotating nut 25 is movably installed on the outer surface of the rotating shaft 22, the ring 21 is movably installed on the outer surface of the rotating nut 25, and one end of the ring 21 is movably connected to the other end of the connecting rod 20.

[0033] When the staff is performing powder metallurgy stamping, after stamping and forming, the motor 24 is turned on, and the output shaft of the motor 24 drives the rotating shaft 22 to rotate. The rotating nut 25 on the surface of the rotating shaft 22 is driven to move in the relative direction on the surface of the rotating shaft 22. When moving, the ring 21 is driven to make the connecting rod 20 pull the connecting block 19 to move downward. When the second module 2 follows the connecting block 19 downward, the processed module will be exposed on the top of the stripping module 7.

[0034] Since the motor 24 is turned on, the output shaft of the motor 24 drives the rotating shaft 22 to rotate, and the rotating nut 25 on the surface of the rotating shaft 22 is driven to move in the relative direction on the surface of the rotating shaft 22, and the movement drives the ring 21 to make the connecting rod 20 pull the connecting block 19 to move downward. When the second module 2 follows the connecting block 19 downward, the processed module will be exposed on the top of the demolding module 7. Compared with the traditional stamping die, the new demolding mechanism rotates the rotating shaft 22 to move the rotating nuts 25 on both sides in opposite directions at the same time, so that the connecting block 19 pulls the second module 2 downward, so that the module is exposed on the top of the demolding module 7, which is convenient for the clamping arm 16 to collect, more convenient for demolding, and improved work efficiency.

The rotating nut 25 on the surface of the rotating shaft 22 is driven to move in the relative direction on the surface of the rotating shaft 22. When moving, the ring 21 is driven to make the connecting rod 20 pull the connecting block 19 to move downward. When the second module 2 follows the connecting block 19 downward, the processed module will be exposed on the top of the stripping module 7.

[0051] When the powder is stamped and then demolded, the clamping arm 16 turns on the exhaust fan 14 when clamping the formed powder. The exhaust fan 14 provides suction for the exhaust head 17. The exhaust head 17 moves with the clamping arm 16 to draw the powder on the surface of the second module 2 and the powder on the mold into the exhaust head 17 and transport it to the inside of the powder collection box 13 through the connecting hose 15.
