After the raw material is punched into a sealing ring, the lower die 7 can be moved forward along the translation frame 6, so that the lower die 7 sequentially surrounds the outer ring blade 803 and the driving rack 605.

[0026] Please refer to the figure again Figure 2 and Figure 3 A trapezoidal lead screw 602 is provided at the bottom of the translation frame 6, a lead screw slider 603 is provided on the trapezoidal lead screw 602, a servo motor 604 is connected to the trapezoidal lead screw 602, a positioning arm 8 is connected to the hydraulic cylinder 1, an outer ring blade 803 and an inner ring blade 804 are provided below the positioning arm 8, a connecting leg 801 is provided on the positioning arm 8, a positioning knife seat 802 is provided on the outer ring blade 803 and the inner ring blade 804, and the positioning knife seat 802 is fixed on the connecting leg 801.

[0027] Specifically, the servo motor 604 can drive the trapezoidal lead screw 602 to rotate. After the trapezoidal lead screw 602 rotates, it will drive the lead screw slider 603 to move forward. After the lead screw slider 603 moves forward, it will drive the movable slider 703 to move forward. After the movable slider 703 moves forward, it will drive the lower mold 7 to move forward. After the lower mold 7 moves forward to below the outer ring blade 803 and the inner ring blade 804, the hydraulic cylinder 1 can drive the outer ring blade 803 and the inner ring blade 804 to move downward to cut off the waste on the edge of the sealing ring.

[0028] Please refer again Figure 1 , Figure 3 and Figure 4 A driving rack 605 is fixedly installed on one side of the translation frame 6, a servo motor 604 is connected to the trapezoidal lead screw 602, a lower mold 7 is movably installed on the translation frame 6, movable shafts 704 are provided on both sides of the lower mold 7, a movable slider 703 is connected to the movable shaft 704, a steering gear 705 is fixedly installed at the end of the movable shaft 704, and a movable slide groove 601 is opened on the translation frame 6.

[0029] Specifically, after the waste material on the edge of the sealing ring is cut off, the servo motor 604 can be started again to make the lower mold 7 continue to move forward. After the lower mold 7 continues to move forward, the steering gear 705 will engage with the driving rack 605. The steering gear 705 will rotate when it moves forward and passes the driving rack 605. After the steering gear 705 rotates 180°, it will drive the lower mold 7 on the movable shaft 704 to rotate 180°, so that the lower mold 7 is inverted, and the sealing ring in the lower mold 7 is poured out, thereby realizing automatic unloading.

[0030] Working principle: When in use, first place the raw material in the lower die 7. After the raw material is placed in the lower die 7, the hydraulic cylinder 1 can be controlled to move downward. After the hydraulic cylinder 1 moves downward, it will drive the upper die 4 to move downward, thereby squeezing the raw material in the lower die 7 into a sealing ring. After the raw material in the lower die 7 is squeezed into a sealing ring, the upper die 4 can be slightly lifted. After slightly lifting the upper die 4, the servo motor 604 can be started. After starting the servo motor 604, it will drive the trapezoidal lead screw 602 to rotate. After the trapezoidal lead screw 602 rotates, it will drive the lead screw slider 603 to move forward. After the lead screw slider 603 moves forward, it will drive the movable slider 703 to move forward. After the movable slider 703 moves forward, it will drive the lower die 7 to move forward. The lower die 7 moves forward to below the outer ring blade 803 and the inner ring blade 804 After that, the servo motor 604 can be stopped. After stopping the servo motor 604, the hydraulic cylinder 1 can be controlled to move downward again, so that the outer ring blade 803 and the inner ring blade 804 move downward, thereby cutting off the waste material on the edge of the sealing ring. After the waste material on the edge of the sealing ring is cut off, the hydraulic cylinder 1 can be retracted and the lower mold 7 can be controlled to continue to move forward. After the lower mold 7 continues to move forward, the steering gear 705 will engage with the driving rack 605. The length of the driving rack 605 is half of the outer diameter of the steering gear 705. The steering gear 705 will rotate 180° when it moves forward and passes the driving rack 605. After the steering gear 705 rotates 180°, it will drive the lower mold 7 on the movable shaft 704 to rotate 180°, so that the lower mold 7 is inverted, and the sealing ring in the lower mold 7 is poured out, thereby realizing automatic unloading and improving processing efficiency.
