[0002] The car roof is a part of the car interior, which mainly plays the role of decoration, sound absorption, heat insulation, etc. During the production process of the car roof, the pressed car roof needs to be trimmed.

[0003] China Patent Authorization Announcement No.: CN211112867U, provides a workbench for trimming the ceiling fabric for vehicles. This patent drives the upper sample frame to rise and fall through a motor and a chain. After the trimming is completed, the motor drives the push plate to push the trimmed ceiling fabric onto the conveyor belt, reducing the labor intensity of workers and improving work efficiency.

[0004] In the existing technology, when trimming the car roof, it is inevitable that metal debris will be generated on the top surface of the car roof. These metal debris are often cleaned up by the staff after the trimming operation is completed. However, during the trimming process, these debris will be pressed on the top surface of the car roof by the hydraulic equipment used for trimming, thereby causing dents on the top surface of the car roof and reducing the quality of the trimming device.

[0032] Embodiment 1:

[0033] See also Figure 1 - Figure 3 A car roof mold that is easy to trim, including a mold body 1, a mold groove 11 is opened at the top of the mold body 1, a mounting groove 13 is opened at the top of the mold body 1, the mounting groove 13 is arranged on one side of the mold groove 11, and a plurality of elastic air bags 2 are fixedly connected inside the mounting groove 13, one end of the plurality of elastic air bags 2 are fixedly connected to an air nozzle 21, and the plurality of air nozzles 21 are distributed on one side of the inner wall of the mold groove 11.

[0034] Slide grooves 12 are provided on both sides of the mold body 1 , and guide cylinders 3 are provided on both sides of the mold body 1 . The two guide cylinders 3 are slidably connected to the two slide grooves 12 respectively.

[0035] The interiors of the two guide cylinders 3 are fixedly connected with return springs 4 , and the top ends of the two return springs 4 are fixedly connected with mounting plates 5 .

[0036] A pressing block 6 is fixedly connected to the bottom end of one of the mounting plates 5 , and the pressing block 6 is slidably connected to the mounting groove 13 .

[0037] A through groove 14 is formed on the inner wall of the mold groove 11 away from the air nozzle 21 , and a collecting groove 15 is formed on the top of the mold body 1 . The collecting groove 15 and the mounting groove 13 are symmetrically distributed on both sides of the mold groove 11 , and the through groove 14 is connected to the collecting groove 15 .

[0038] The specific implementation process of this embodiment is as follows: the internal material of the elastic airbag 2 is elastic sponge. When the elastic airbag 2 is squeezed, the gas in the elastic sponge inside it will be released. After the squeezing force disappears, the elastic sponge will restore its original shape and re-absorb the gas. The elastic airbag 2 and the air nozzle 21 are connected through a connecting pipe, and the connecting pipe is arranged in the groove wall of the mold groove 11.

[0039] A hydraulic device is arranged above the mold body 1 to press the mounting plate 5 downward, and the pressing block 6 will press the elastic airbag 2 to eject the internal gas from the air nozzle 21, thereby blowing away the debris generated during cutting. The debris will be blown into the through groove 14 and finally fall into the collecting groove 15, so that the debris generated during cutting can be cleaned up in time to prevent the debris from being pressed on the surface of the ceiling by the hydraulic equipment during multiple cutting processes, eventually causing dents and reducing the cutting quality.

[0040] Embodiment 2:

[0041] See also Figure 1 , Figure 3 , Figure 4 and Figure 5Two guide frames 7 are fixedly connected between the two mounting plates 5 , and ratchet belts 71 are fixedly connected to the bottom ends of the inner walls of the two guide frames 7 .

[0042] Ratchet wheels 8 are disposed inside the two guide frames 7 , and the two ratchet wheels 8 are respectively meshed with two ratchet belts 71 .

[0043] A rotating rod 9 is fixedly connected between the ratchets 8 , and a cutting knife 10 is rotatably connected to the outside of the rotating rod 9 . The cutting knife 10 is arranged between the two guide frames 7 .

[0044] The specific implementation process of this embodiment is as follows: the ratchet 8 can rotate in the guide frame 7, and a handle or knob is installed at one end of the rotating rod 9, which can facilitate the staff to rotate the ratchet 8. When the rotating rod 9 rotates, the ratchet 8 will rotate along the ratchet belt 71 inside the guide frame 7. At this time, the rotating rod 9 drives the cutting knife 10 to move between the two guide frames 7, thereby changing the position of the cutting knife 10, making it convenient for the staff to adjust the position of the cutting knife 10, and cooperating with the slidable guide cylinder 3, the cutting range of the cutting knife 10 is enlarged, the application range of the device is expanded, and the flexibility of the device during cutting is improved.

[0045] The working principle of the utility model is as follows: the staff first places the ceiling that needs to be trimmed in the mold groove 11, and then twists the rotating rod 9 by hand to change the position of the cutting knife 10. After adjusting to the appropriate trimming position, the staff loosens the rotating rod 9, and the ratchet 8 and the ratchet belt 71 fix the position of the cutting knife 10 through the meshing self-locking effect. Then the staff slides the guide cylinder 3 to the appropriate trimming position and turns on the external hydraulic equipment. The external hydraulic equipment lowers the mounting plate 5, so that the cutting knife 10 performs trimming operation on the ceiling. During this process, the pressing block 6 squeezes the elastic airbag 2, and the internal gas of the elastic airbag 2 is ejected from the air nozzle 21, thereby blowing the debris generated during trimming into the through groove 14, and these debris will eventually fall into the collection groove 15. The staff needs to regularly clean the debris inside the collection groove 15.

[0046] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
