The output shaft of the first motor 15 is fixedly connected to a drive rod 14 that passes through the connecting plate 2 and extends to its top. A placement plate 10 is fixedly connected to the top surface of the drive rod 14. Four rotating rods 20 are rotatably connected to the outer peripheral wall of the placement plate 10 through bearings.

[0030] Specifically, the bottom injection molded part falls downwards and enters the placement chamber 12. The placement chamber 12 restricts the injection molded part. The first motor 15 is started, and the output shaft of the first motor 15 drives the drive rod 14 to rotate, causing the placement plate 10 to rotate. This aligns the placement chamber 12 with the high-speed camera 7, which then inspects the surface of the injection molded part. The inspection results are displayed on the display screen 13.

[0031] It should be noted that the lamp 5, the battery 23, the high-speed camera 7, and the display screen 13 are all conventional devices known to the public in the prior art, and their specific structures and working principles will not be described in detail in this article.

[0032] Please see Figures 1 to 4 In this embodiment, the connecting plate 2 is provided with a support assembly for supporting the placement chamber 12.

A battery 23 is fixedly installed inside each of the four mounting grooves 22. The top surface of the placement plate 10 is provided with a finished product discharge groove 19 and a waste product discharge groove 17. The bottom of the connecting plate 2 is provided with a waste product collection chamber 16 and a finished product collection chamber 18 from left to right.

[0034] Specifically, the placement chamber 12 is supported by the sliding connection between the support rod 4 and the support groove 3, which improves the stability of the placement chamber 12. The second motor 21 is started, and the second motor 21 drives the rotating rod 20 to rotate, so that the opening of the placement chamber 12 is at the bottom, and the injection molded part is discharged from the placement chamber 12. The finished product passes through the finished product discharge groove 19 and enters the interior of the finished product collection chamber 18, and the waste product passes through the waste product discharge groove 17 and enters the interior of the waste collection chamber 16.

[0035] Please see Figures 1 to 4In this embodiment, the fixing frame 6 is provided with a feeding assembly for feeding the injection molded parts. The feeding assembly includes a connecting chamber 9. One end of the connecting chamber 9 is fixedly connected to the top surface of the fixing frame 6, and the other end passes through the fixing frame 6 and extends into its interior. First electric push rods 24 are fixedly installed on the front and back of the connecting chamber 9. Sliding grooves 25 are opened on the front and back of the connecting chamber 9. The output ends of the two first electric push rods 24 are fixedly connected to a sliding plate 26 with one end extending into the sliding groove 25. Second electric push rods 27 are fixedly installed on the side of the two sliding plates 26 away from the connecting chamber 9. The output ends of the two second electric push rods 27 pass through the two sliding plates 26 respectively. Clamping plates 11 are fixedly connected to the output ends of the two second electric push rods 27.

[0036] Among them, the sliding plate 26 is an L-shaped plate, and the sliding plate 26 and the sliding groove 25 are slidably connected.

[0037] Specifically, multiple injection molded parts are stacked inside the connecting chamber 9. The second electric push rod 27 is activated, and its output end drives the clamping plate 11 to move. The clamping plate 11 fits against the injection molded parts, fixing them in place. The placement chamber 12 is located at the bottom of the connecting chamber 9. The clamping plate 11 is released, and the bottom injection molded parts fall downwards into the placement chamber 12. The placement chamber 12 restricts the injection molded parts. The first electric push rod 24 is activated, and its output end drives the sliding plate 26 to move upwards, causing the clamping plate 11 to move upwards.

[0038] It should be noted that the first electric actuator 24 and the second electric actuator 27 are both conventional devices known in the prior art, and their specific structures and working principles will not be described in detail here. This application can ensure that the output ends of the two first electric actuators 24 and the two second electric actuators 27 extend and retract simultaneously by using a synchronization controller or other synchronization device, thereby achieving synchronous operation. These synchronization devices are common and mature in the field of electric control, and therefore will not be described in detail in the specific embodiments.

[0039] The working principle of the above embodiments is as follows:

[0040] Multiple injection molded parts are stacked inside the connecting chamber 9. The second electric push rod 27 is activated, and its output end moves the clamping plate 11. The clamping plate 11 fits against the injection molded parts, fixing them in place. The placement chamber 12 is located at the bottom of the connecting chamber 9. The clamping plate 11 is released, and the bottom injection molded parts fall downwards into the placement chamber 12. The placement chamber 12 then restrains the injection molded parts. The first electric push rod 24 is activated, and its output end moves the sliding plate 26 upwards, causing the clamping plate 11 to move upwards. The clamping plate 11 aligns with the remaining injection molded parts, and then resets, fixing the remaining injection molded parts. The sliding connection between the sliding plate 26 and the sliding groove 25 supports the clamping plate 11, raising it. To improve stability, the first motor 15 is started, and the output shaft of the first motor 15 drives the drive rod 14 to rotate, causing the placement plate 10 to rotate, thereby aligning the placement chamber 12 with the high-speed camera 7. The high-speed camera 7 inspects the surface of the injection molded part, and the inspection results are displayed on the display screen 13. The placement chamber 12 is supported by the sliding connection between the support rod 4 and the support groove 3, improving the stability of the placement chamber 12. The second motor 21 is started, and the second motor 21 drives the rotating rod 20 to rotate, so that the opening of the placement chamber 12 is at the bottom, and the injection molded part is discharged from the placement chamber 12. The finished product passes through the finished product discharge chute 19 and enters the interior of the finished product collection chamber 18, while the waste product passes through the waste product discharge chute 17 and enters the interior of the waste collection chamber 16.
