[0002] Injection molded parts are typically formed using injection molds. After molding, the gate used to form the injection molded part, commonly known in the industry as the sprue, produces excess molded material. When the injection molded part is to be used after molding, the sprue needs to be cut off. In related technologies, the sprue is usually removed by workers using knives or clamps.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] To address the technical issues in existing fully automatic sprue punching fixtures where the cutter position cannot be guaranteed to be accurate during adjustment, and where the angle of the punching tool affects the punching quality, please refer to [link to relevant documentation]. Figure 1 - Figure 5 , Figure 7 - Figure 9 The following technical solutions are provided:
[0042] A punching fixture with a structure that improves the accuracy of sprue cutting includes:
[0043] The punching fixture body 1 is used for punching the sprue of the workpiece, and the lower end of the punching fixture body 1 is provided with an integrally formed positioning groove 104, which is used to fix the workpiece to be processed.
[0044] It also includes:
[0045] Mounting frame 4, which is used to mount the fixture assembly, is located inside the punching fixture body 1. Lifting frames 3 are mounted on both sides of the mounting frame 4. A first detection plate 403 for detecting the position of the workpiece is provided at the lower end of the mounting frame 4. A connecting frame 401 for movement is mounted at the upper end of the mounting frame 4. A positioning sleeve 405 is installed inside the connecting frame 401.

[0047] The movable cutting seat 8, which is used to precisely adjust the punching position, is located inside the side punching assembly frame 5. A detection gear 802 for positioning is installed on the outer side of the movable cutting seat 8. The detection gear 802 is meshed with the elastic gear row 501. A third electric cylinder 801 is installed inside the movable cutting seat 8. A cutting head 805 for punching the sprue is installed at the lower end of the movable cutting seat 8.
[0048] The precision detection frame 9, which is used to detect the precise position of the moving cutting seat 8, is located inside the side punching assembly frame 5. A pressure monitoring sensor 903 for detecting the position of the pressure-bearing elastic toothed row 501 is provided on one side of the precision detection frame 9. The pressure monitoring sensor 903 adopts a TK438W diaphragm sealed pressure transmitter.
[0049] Specifically, before punching, the position and distance of the workpiece are detected by multiple laser detection sensors 404 at the lower end of the first detection plate 403, and the laser ranging and balance sensor 4052 inside the second detection plate 4051 detects the angle between the connecting frame 401 and the fixed slide plate 7. After the two are found to be in balance, subsequent processing can be carried out. Thus, before punching, the position of the detection fixture is stabilized, improving the working quality of the fixture and the punching accuracy. During the movement of the moving cutting seat 8, the elastic tooth row 501 is slightly pressed down on the squeezing block 905, so that the pressure monitoring sensor 903 senses the specific position of the detection gear 802. Thus, in the work of positioning, the detection accuracy is maximized to improve the working quality of automated punching, and the position of the cutting head 805 corresponds to the detection position of the laser detection sensor 404, with high precision.
[0050] To address the technical problem in existing technologies where the unstable structure of fixtures affects the processing quality of automated equipment during operation, please refer to [link to relevant documentation]. Figure 1 - Figure 3 The following technical solutions are provided:

The upper end of the first electric cylinder 201 and the first electric cylinder 201 are fixedly connected to the punching fixture body 1. The motor shaft of the servo motor 2 is connected to the first electric cylinder 201 for transmission. The lower end of the first electric cylinder 201 is connected to a lifting frame 3 by fixing screws.
[0053] The fixed slide plate 7 is slidably connected to the positioning sleeve plate 405, and the two ends of the fixed slide plate 7 are respectively connected to the two lifting frames 3 by fixing screws. The two sides of the inside of the punching fixture body 1 are provided with integrally formed positioning grooves 107. One end of the lifting frame 3 is embedded in the positioning groove 107 and slidably connected to the punching fixture body 1. A sliding rod runs through the inside of the lifting frame 3, and the sliding rod is used to maintain the movement stability of the lifting frame 3.
[0054] Specifically, after the punching fixture body 1 is fixed, the two sides of the punching fixture body 1 are fixed by the counterweight inside the protective plate 102 to maintain balance. At the same time, the servo motor 2 and the first electric cylinder 201 can be fixedly installed by the mounting cover plate 103. After the position is stable, the first electric cylinder 201 can push the lifting frame 3 to slide inside the punching fixture body 1. The positioning slide groove 107 keeps the fixed slide plate 7 and the lifting frame 3 stable. The first electric cylinder 201 and the second electric cylinder 701 perform dual-axis movement, making wide-range adjustments, and the position stability of the adjustment is high.
[0055] To address the technical problem in existing technologies where the structure of automatic fixture components is generally unstable, affecting the punching accuracy of the sprue and hindering long-term operation, please refer to [the relevant documentation / reference]. Figure 3 , Figure 9 - Figure 10 The following technical solutions are provided:
[0056] Both side punching assembly frames 5 are welded to the mounting frame 4. A fixing plate 402 is installed in the middle of the interior of the mounting frame 4. The fixing plate 402 is used to weld the connecting frame 401 and the mounting frame 4. The positioning sleeve 405 passes through the connecting frame 401 and is welded to the connecting frame 401.

[0058] Specifically, before punching, the position and distance of the workpiece are detected by multiple laser detection sensors 404 at the lower end of the first detection plate 403. The processor module 407 controls the extension and retraction of the second electric cylinder 701. The second electric cylinder 701 pushes the mounting frame 4 and the connecting frame 401 to slide outside the fixed slide plate 7, so that the side punching assembly 5 moves above the position of the workpiece. Before and after the movement, the laser ranging balance sensor 4052 inside the second detection plate 4051 detects the angle between the connecting frame 401 and the fixed slide plate 7. After the two are found to be in balance, the subsequent processing work can be carried out. Thus, before punching, the position of the fixture is stabilized, improving the working quality of the fixture and the punching accuracy.
[0059] To address the technical problem in existing jigs that cannot quickly position injection-molded parts, thus affecting work efficiency, please refer to [link to relevant documentation]. Figure 1 , Figure 11 The following technical solutions are provided:
[0060] The positioning groove 104 is equipped with a positioning push plate 105 for automatically fixing the workpiece, and the positioning groove 104 is also equipped with two integrally formed limiting partition strips 106.

The electric motor 109 is connected to the threaded screws 108 by belt drive.
[0061] Specifically, during operation, the workpiece can be placed in the positioning groove 104. Depending on the type of workpiece, a positioning groove 104 of different widths can be selected. Then, the electric motor 109 drives the threaded screw 108 to rotate. The threaded screw 108 drives the positioning push plate 105 to move inside the positioning groove 104, so that the workpiece is fixed inside the positioning groove 104, thus allowing subsequent punching operations to be performed.
[0062] To address the technical problem of insufficient accuracy in punching position detection by existing automated fixtures, please refer to [link / reference needed]. Figure 1 , Figure 6 - Figure 8 The following technical solutions are provided:
[0063] Both sides of the upper end of the side punching assembly frame 5 are equipped with a side magnetic brake motor 502, and a bearing seat 504 is installed in the middle of the side punching assembly frame 5. A threaded rod 503 is installed at one end of the side magnetic brake motor 502.

[0064] A limiting gear frame 8021 is provided on one side of the movable cutting base 8. The detection gear 802 is rotatably connected to the limiting gear frame 8021 via a rotating shaft. An integrally formed limiting plate 803 is provided at the lower end of the movable cutting base 8. A telescopic column 804 is installed inside the limiting plate 803. The lower end of the telescopic column 804 is welded to the cutting head 805. The lower end of the third electric cylinder 801 is connected to the telescopic column 804 via fixing screws.

[0066] Specifically, during the punching process, the threaded rod 503 is rotated by the side magnetic brake motor 502, which in turn moves the movable cutting seat 8. During the movement, the movable cutting seat 8 can drive the detection gear 802 to rotate on the surface of the elastic toothed rack 501. During the rotation, the elastic toothed rack 501 is slightly pressed down on the pressing block 905, which allows the pressure monitoring sensor 903 to sense the specific position of the detection gear 802. This maximizes the detection accuracy in the positioning process, thereby improving the quality of automated punching and ensuring that the position of the cutting head 805 corresponds to the detection position of the laser detection sensor 404, resulting in high precision.
[0067] To address the technical problem in existing technologies where the control module of a fixture operates in a poor environment, making it unsuitable for long-term operation, please refer to [link / reference needed]. Figure 1 , Figure 4 , Figure 9 - Figure 10 The following technical solutions are provided:
[0068] A heat sink 6 is provided on the top of the connecting frame 401. A connecting rod is installed on the outside of the heat sink 6, and a fastener 406 is provided on the outside of the connecting frame 401. The fastener 406 is fixedly connected to the connecting frame 401 and the heat sink 6 respectively. The heat sink 6 is used to cool the processor module 407. A second electric cylinder 701 is installed on the lower end of one side of the fixed slide plate 7. One end of the second electric cylinder 701 is connected to the fastener 406 by a fixing screw. The processor module 407 is electrically connected to the side magnetic brake motor 502, the first electric cylinder 201 and the second electric cylinder 701. The processor module 407 adopts an Em104-a5362 industrial CPU module.
[0069] Specifically, during the processing, after the position is detected by the detection sensor, the processor module 407 controls the electric equipment to move automatically and make precise adjustments. At the same time, it stops working on components with abnormal positions, reduces processing errors, improves work quality, and cools the processor module 407 through the heat sink 6 to maintain the working effect of the processor module 407.
[0070] Working principle: The punching fixture body 1 is installed above the worktable. After the punching fixture body 1 is fixed, the two sides of the punching fixture body 1 are fixed by the counterweight inside the protective plate 102 to maintain balance. At the same time, the servo motor 2 and the first electric cylinder 201 are fixedly installed by the mounting cover plate 103. After the position is stable, the first electric cylinder 201 can push the lifting frame 3 to slide inside the punching fixture body 1. The positioning slide 7 and the lifting frame 3 are kept stable by the positioning slide groove 107. During operation, the workpiece can be placed in the positioning groove 104. The positioning groove 104 of different widths is selected according to the corresponding type of workpiece. Then, the electric motor 109 drives the threaded screw 108. Rotation causes the threaded screw 108 to move the positioning push plate 105 within the positioning groove 104, keeping the workpiece fixed within the groove and allowing subsequent punching operations. Before punching, the position and distance of the workpiece are detected by multiple laser detection sensors 404 at the lower end of the first detection plate 403. The processor module 407 controls the extension and retraction of the second electric cylinder 701, which pushes the mounting frame 4 and the connecting frame 401 to slide outside the fixed slide plate 7, moving the side punching assembly 5 above the workpiece. Before and after movement, the connecting frame is detected by the laser ranging and balance sensor 4052 inside the second detection plate 4051. The angle between 401 and the fixed slide plate 7 is checked. After they are balanced, subsequent processing can be carried out. This ensures the stability of the fixture position before punching, improving the fixture's working quality and punching accuracy. During punching, the threaded rod 503 is rotated by the magnetic brake motor 502, which in turn moves the moving cutting seat 8. During the movement of the moving cutting seat 8, the detection gear 802 rotates on the surface of the elastic toothed rack 501. During the rotation, the elastic toothed rack 501 is slightly pressed down on the pressing block 905, allowing the pressure monitoring sensor 903 to sense the specific position of the detection gear 802. This maximizes the detection accuracy during position positioning. The highly automated punching process ensures that the position of the cutting head 805 corresponds to the detection position of the laser detection sensor 404, resulting in high precision and excellent work quality. Dual-axis movement via the first electric cylinder 201 and the second electric cylinder 701 allows for a wide range of adjustments with high positional stability. The extension of the third electric cylinder 801 drives the cutting head 805 to punch the sprue position. The processor module 407 controls the electric equipment for automated movement and precise adjustment.
