[0037] The power unit includes a first fixing frame 402, a first driving motor 403, and a fixing rod 404; the telescopic ends of the two third cylinders 401 are jointly bolted to the first fixing frame 402; the first driving motor 403 is bolted to the first fixing frame 402; the output shaft of the first driving motor 403 is fixedly connected to the fixing rod 404, and the fixing rod 404 is rotatably connected to the first fixing frame 402; the fixing rod 404 is fixedly connected to all the hollow frames 405.

[0038] The cutting unit includes a first electric push rod 407 and a cutter 408; the first electric push rod 407 is bolted to the lower side of the hollow frame 405; the telescopic end of the first electric push rod 407 is bolted to the cutter 408.

[0039] When the two second cylinders 301 extend to push the hollow plate 302 to drive the support tube 303 to rise, after the flange 003 and the sprue material 004 in the lower mold 205 are ejected through the support tube 303, control the two second electric sliders 103 to slide simultaneously in the left direction on the electric slide rail 101, so that the third cylinder 401 drives the first fixing frame 402 and the parts connected thereto to move in the left direction, making the hollow frame 405 located between the flange 003 and the lower mold 205, and the grinding disc 413 located directly below the flange 003. Then control the two third cylinders 401 to extend, so that the first fixing frame 402 and the parts connected thereto move upward, making the receiving portion 007 of the hollow frame 405 receive the flange 003. At this time, the grinding disc 413 is located inside the flange 003. Then control the second cylinder 301 to contract, so that the hollow plate 302 drives the support tube 303 to move downward to reset. At this time, the sprue material 004 is clamped by an external clamping device. The air duct 406 is externally connected to an air pump to convey air into the hollow frame 405, so that the airbag 414 expands to fix the flange 003. Then control the electric shaft 417 to start. Taking the front-to-back view as a reference, the electric shaft 417 rotates clockwise, thereby driving the grinding plate 418 and the parts connected thereto to rotate clockwise by ninety degrees. Then control the second electric push rod 415 to contract, driving the support frame 416 and the parts connected thereto to move downward, so that the lower side of the grinding plate 418 fits the upper side of the flange 003, the protruding portion 006 is snapped into the annular groove of the flange 003, and the grinding rod 421 fits the outer ring surface of the flange 003. Then control the first electric push rod 407 to extend to push the cutting knife 408 upward, and the cutting knife 408 cuts off the sprue material 004, separating the sprue material 004 from the flange 003. Then the sprue material 004 is taken out by an external clamping device. Then control the second electric slider 103 to slide in the right direction, so that the hollow frame 405 drives the flange 003 to move in the right direction, making all the flanges 003 located on the right side of the lower mold 205. Then control the second driving motor 409 to start. The output shaft of the second driving motor 409 drives the grinding disc 413 and the parts connected thereto to rotate, so that the grinding plate 418 rotates while fitting the upper side of the flange 003, and the grinding rod 421 rotates while fitting the outer ring surface of the flange 003. Due to the frictional force, the grinding rod 421 rotates in the mounting member 420. When the grinding rod 421 passes through the protruding part of the outer ring surface of the flange 003, the grinding rod 421 is squeezed, the elastic member 419 is stretched, and the mounting member 420 slides in the grinding plate 418, so that the grinding rod 421 adapts to the shape of the outer ring surface of the flange 003, and at the same time the mounting member 420 adapts to the upper side area of the protruding part of the flange 003. Thus, the upper side edges of the flange 003 are polished and trimmed through the cooperation of the grinding disc 413, the grinding plate 418 and the mounting member 420, and the outer ring surface edges of the flange 003 are polished and trimmed by the grinding rod 421. The debris generated by grinding falls and is collected in the collection box 3, and some debris remains in the annular groove of the flange 003. After grinding is completed, the second driving motor 409 is turned off.The second electric push rod 415 extends to drive the support frame 416 to drive the electric shaft 417 and the grinding plate 418 to rise and reset. Then, the electric shaft 417 rotates reversely to drive the grinding plate 418 to rotate reversely and reset. At the same time, the first drive motor 403 is controlled to start. Taking the front-to-back view as a reference, the output shaft of the first drive motor 403 rotates clockwise, causing the fixed rod 404 to drive the hollow frame 405 to rotate 180 degrees. Further, the hollow frame 405 drives the flange 003 to flip 180 degrees. At the same time, the debris remaining in the annular groove of the flange 003 falls out and is collected in the collection box 3. An external conveying device is arranged on the right side of the chassis 1. Then, the second electric slider 103 is controlled to slide to the right side, causing the hollow frame 405 to drive the flange 003 to move above the external conveying device. Then, the air pump connected to the air duct 406 is controlled to pump air, causing the airbag 414 to contract and reset. Further, the flange 003 is separated from the hollow frame 405, and the flange 003 is placed on the external conveying device. Then, the flange 003 is conveyed to the subsequent processing procedure through the external conveying device, so as to perform grinding and trimming treatment on the flange 003 during the process of taking out and transferring the flange 003, without manual trimming through turnover, ensuring the trimming quality of the flange 003, reducing the turnover times of the flange 003, shortening the processing cycle of the flange 003, and improving the quality of the flange 003.,

[0041] On the basis of Embodiment 2, as Figures 8-9 shown, it further includes a first cleaning mechanism. The second drive motor 409 is set as a double-shaft motor, and the output shaft below the second drive motor 409 is connected with a first cleaning mechanism; the first cleaning mechanism includes a second fixing frame 410, a cleaning ring 411 and a cleaning plate 412; the output shaft below the second drive motor 409 is fixedly connected with a second fixing frame 410; a cleaning ring 411 is welded on the lower side of the second fixing frame 410, and brush hairs are arranged on the inner wall of the cleaning ring 411; the outer ring surface of the cleaning ring 411 is connected with a cleaning plate 412 through a torsion spring shaft, and brush hairs are arranged on the cleaning plate 412.

[0042] A plurality of arc-shaped guide grooves are formed in the inner wall of the cleaning ring 411 for guiding the waste cleaned by the brush hairs on the inner wall of the cleaning ring 411 to fall off.

[0044] The power group 203 is composed of a micro motor, a belt and a transmission wheel.

[0045] The end of the support tube 303 has magnetism, enhancing the fixing effect on the flange 003 made of magnetic attraction material.

[0046] After the cutting knife 408 cuts off the sprue 004 to separate the sprue 004 from the flange 003, and the sprue 004 is taken out by an external clamping device, control the second electric push rod 415 to extend, so that the support frame 416 and the parts connected thereto rise, so that the grinding plate 418 and the grinding rod 421 are separated from the flange 003. At the same time, control the two third cylinders 401 to contract, so that the first fixing frame 402 and the parts connected thereto move downward, so that the cleaning ring 411 moves downward, so that the cleaning ring 411 is located in the cavity of the lower die 205. At the same time, control the two first cylinders 202 to extend, so that the upper die 204 moves downward, so that the annular strip 001 on the lower side of the upper die 204 is clamped into the U-shaped groove 005. Then control the second driving motor 409 to start, and the second driving motor 409 drives the grinding disc 413 and the second fixing frame 410 to rotate, so that the cleaning ring 411 rotates to clean the waste remaining on the inner ring surface of the cavity of the lower die 205. At the same time, the cleaning plate 412 rotates in contact with the inner wall of the cavity. When the cleaning plate 412 passes through the bent part of the inner wall of the cavity, the cleaning plate 412 is squeezed, so that the cleaning plate 412 rotates around the torsion spring shaft at the connection with the cleaning ring 411, so that the torsion spring shaft is twisted, so that the cleaning plate 412 always fits the inner wall of the cavity, and then the waste remaining on the inner wall and the bottom surface of the cavity is cleaned by the cleaning plate 412. At the same time, the waste falling from the cleaning is pumped out through the support pipe 303. At the same time, the waste remaining on the annular strip 001 is scraped off by the cleaning frame 422. When the bristles on the cleaning frame 422 are aligned with the round rod 002, the second driving motor 409 stops rotating, and the power unit 203 drives the round rod 002 to rotate, so that the round rod 002 is cleaned by the bristles on the cleaning frame 422, so as to ensure the cleanliness of the upper die 204 and the lower die 205 and avoid waste residue from affecting the quality of subsequent products. After the cleaning is completed, the first cylinder 202 contracts to drive the upper die 204 to reset, the third cylinder 401 extends to make the first fixing frame 402 rise and reset, and the second electric push rod 415 contracts to make the support frame 416 drive the electric shaft 417 and the grinding plate 418 to move downward, so that the lower side of the grinding plate 418 fits the upper side of the flange 003, and then the subsequent trimming operation is carried out.
