[0030] Example

[0031] like Figure 1-4 As shown, the water cutting device described in the embodiment of the present application includes a frame 1, a bracket 2, a driving mechanism 3, a supporting plate 4, a clamping mechanism 5, a carrier 6 and a cutting mechanism 7. The bracket 2, the driving mechanism 3 and the supporting plate 4 are all arranged on the frame 1, the clamping mechanism 5 is arranged on the bracket 2, the driving mechanism 3 drives the supporting plate 4 to reciprocate, the carrier 6 and the cutting mechanism 7 are both arranged on the supporting plate 4, and the cutting mechanism 7 is located on the side of the carrier 6.

[0032] During use, after the material taking and discharging robot places the injection molded part 26 with the water outlet 27 to be cut off on the carrier 6, the driving mechanism 3 drives the supporting plate 4 to move, and the supporting plate 4 drives the carrier 6 to move synchronously until the injection molded part 26 is located below the clamping mechanism 5 and stops. The clamping mechanism 5 clamps the injection molded part 26, and the cutting mechanism 7 cuts the water outlet 27 on the injection molded part 26. After the water outlet 27 is cut, the clamping mechanism 5 leaves the injection molded part 26, and the driving mechanism 3 drives the supporting plate 4 to return to the initial position. The supporting plate 4 drives the carrier 6 to move synchronously, which makes it convenient for the material taking and discharging robot to take away the injection molded part 26 with the water outlet 27 cut off and place the next injection molded part 26 with the water outlet 27 cut off, thereby reducing the labor intensity of personnel and improving production efficiency.

[0033] In this embodiment, sliders 8 are respectively provided at both ends of the bottom of the supporting plate 4, and slide rails 9 are relatively provided on the frame 1.

The first cylinder 10 drives the connecting block 11, and the connecting block 11 fixes the supporting plate 4. When in use, the material taking and unloading robot places the injection molded part 26 with the water outlet 27 to be cut off on the carrier 6, and then the first cylinder 10 extends and retracts, and the connecting block 11 drives the supporting plate 4 to move, and stops after the injection molded part 26 is located under the clamping mechanism 5, so that the clamping mechanism 5 can clamp the injection molded part 26, thereby facilitating the cutting mechanism 7 to cut the water outlet 27 on the injection molded part 26. After the water outlet 27 is cut, the clamping mechanism 5 is reset, the first cylinder 10 extends, and the connecting block 11 drives the supporting plate 4 to move, so that the supporting plate 4 returns to its initial position, so that the material taking and unloading robot can take away the injection molded part 26 with the water outlet 27 cut off and place the next injection molded part 26 with the water outlet to be cut off.

[0035] In this embodiment, the clamping mechanism 5 includes a mounting frame 12, a second cylinder 13 and a pressure plate 14. The mounting frame 12 includes a mounting plate 15 and a plurality of positioning rods 16. The positioning rods 16 are arranged between the bracket 2 and the mounting plate 15. The second cylinder 13 is arranged on the mounting plate 15. The second cylinder 13 drives the pressure plate 14 to move closer to or away from the frame 1. During use, when the driving mechanism 3 drives the supporting plate 4 to move to the bottom of the pressure plate 14, the second cylinder 13 drives the pressure plate 14 to move downward, and uses the pressure plate 14 to press the injection molded part 26, thereby facilitating the cutting mechanism 7 to cut the water outlet 27. After the water outlet 27 is completed, the second cylinder 13 drives the pressure plate 14 to move upward, so that the pressure plate 14 is away from the injection molded part 26, and the driving mechanism 3 drives the supporting plate 4 back to its initial position.

[0036] In this embodiment, the clamping mechanism 5 also includes multiple guide rods 17, one end of the guide rod 17 is fixedly connected to the pressure plate 14, and the other end of the guide rod 17 is movably inserted into the mounting plate 15. By providing the guide rod 17, the pressure plate 14 can be ensured to operate smoothly.

[0037] In this embodiment, the clamping mechanism 5 also includes a plurality of limit members 18, which are arranged at the end of the guide rod 17 away from the pressure plate 14. The limit members 18 can limit the guide rod 17. The limit members 18 adopt round head nuts.
