[0027] Among them, the adjustment mechanism 2 includes a dual-axis motor 201 fixed in the middle of the inner bottom wall of the fixed box 1, and the output shaft of the dual-axis motor 201 is fixed with a threaded rod 202 which is rotatably connected to the inner wall of the fixed box 1. The outer surface of the threaded rod 202 is threadedly connected with a moving block 203, and the lower surface of the moving block 203 is fixed to the upper surface of the connecting box 3. An adjustment hole is opened on the lower surface of the fixed box 1, and the thread directions of the two threaded rods 202 are opposite. The dual-axis motor 201 drives the moving block 203 and the connecting box 3 to move, which is convenient for the subsequent clamping of the injection molded parts to be clamped.

[0028] It should be noted that the starting component provides a power source for the fixing component, and the fixing component cooperates with the buffer component and the adjustment mechanism 2, so that different types of injection molded parts to be clamped can be stably clamped, further ensuring the stability of the device operation.

[0029] See also Figure 1-4 In order to improve the clamping effect of the device on the injection molded part to be clamped, the fixing mechanism 4 in this embodiment includes a starting component, the fixing mechanism 4 also includes a fixing component, and a buffer component is provided on the fixing component. The starting component includes a driving motor 401 fixed to the opposite side of the two connecting boxes 3, and the output shaft of the driving motor 401 is fixed with a rotating rod 402 that penetrates the inside of the connecting box 3. The end of the rotating rod 402 away from the driving motor 401 is rotatably connected to the inner wall of the connecting box 3 through a bearing, so that the rotation of the rotating rod 402 is more stable. A gear 403 is fixed on the outer surface of the rotating rod 402. By starting the driving motor 401, the gear 403 is driven to rotate to provide power for the fixing component. The fixing component includes a fixed between the front and rear sides of the inner cavity of the connecting box 3 Two fixed rods 404, the outer surface of which is slidably connected with a tooth plate 405, the tooth plate 405 is meshed with the gear 403, the cross-section of the connecting block 406 is convex, so that the gear 403 can drive the tooth plate 405 to rotate, thereby driving the connecting block 406 to move, and two moving holes are provided on the opposite sides of the two connecting boxes 3, and the moving holes are slidably connected to the connecting block 406, and the left and right tooth plates 405 are fixed on the opposite sides thereof with a connecting block 406 that penetrates the outside of the connecting box 3, so that the movement of the connecting block 406 is more stable, and the left and right connecting blocks 406 are fixed on the opposite sides thereof with a connecting plate 407, and the rotation of the gear 403 can prompt the tooth plate 405 to drive the connecting block 406 and the connecting plate 407 to move.

[0030] Among them, the buffer component includes two groups of connecting grooves 408 opened on the opposite sides of the front and rear connecting plates 407, and the inner wall of the connecting groove 408 is slidably connected with an adjusting block 410, and springs 409 are fixed on the opposite sides of the front and rear adjusting blocks 410, and fixing plates 411 are fixed on the opposite sides of the front and rear groups of adjusting blocks 410. The cross-sections of the connecting grooves 408 and the adjusting blocks 410 are convex, and the end of the spring 409 away from the adjusting block 410 is fixed to the inner wall of the connecting groove 408, so that when the fixing plate 411 fixes the injection molded part, the rigid contact between the injection molded part and the fixing plate 411 is effectively avoided, thereby playing a certain protective role on the injection molded part.

[0031] The working principle of the above embodiment is:

[0032] First, the dual-axis motor 201 is started to drive the threaded rod 202 to rotate, thereby driving the two moving blocks 203 and the connecting box 3 to move, and adjusting them according to the model of the injection molded part to be clamped until they are adjusted to a suitable position. At this time, the left and right sides of the injection molded part to be clamped can be clamped, and then the driving motor 401 is started again to drive the rotating rod 402 and the gear 403 to rotate. The rotation of the gear 403 can prompt the two tooth plates 405 to move along the two fixed rods 404 respectively, so that the two connecting blocks 406 and the two connecting plates 407 can move relative to each other, and then the two groups of fixed plates 411 can be driven to move, so that the front and back sides of the injection molded part to be clamped can be fixed, and the injection molded parts of different models to be clamped can be stably clamped. At the same time, when the fixed plate 411 fixes the injection molded part to be clamped, the impact force generated by the movement of the adjusting block 410 driven by the fixed plate 411 is buffered by the elastic force generated by the adjusting block 410, thereby facilitating the avoidance of rigid contact between the injection molded part and the fixed plate 411, which can further extend the service life of the device.
