A moving plate 10 is fixed between the lower end surfaces of the limiting rods 12. A matching sealing frame 11 is fixed between the outer sides of the moving plate 10. The outer sides of the coating die are in a matching and fitting state with the corresponding positions in the first placement groove 4 on the upper module 1. When the coating die is used, it can easily adjust the cavity pressure in the coating die when facing different coating materials, different coating thickness requirements and complex coating conditions. It is also easy to ensure the accuracy of the cavity pressure adjustment, which helps to ensure the stability of the coating die in product processing, so as to reduce the scrap rate when the coating die is processing the product and help to ensure the working efficiency of the coating die in product processing.

[0033] The lower module 2 has a through hole 8 at the bottom center that communicates with the second retention groove 5. The end of the through hole 8 away from the second retention groove 5 penetrates the outer surface of the middle part of the upper side of the lower module 2. The through hole 8 facilitates communication with the second retention groove 5 on the lower module 2. A connecting pipe 14 is fixed to the outer side of the through hole 8 away from the second retention groove 5 on the lower module 2. The connecting pipe 14 is horizontal, and its interior is connected to the through hole 8 on the lower module 2. 2. It can fix and limit the connecting pipe 14, so as to facilitate the stable use of the connecting pipe 14; the upper module 1 is in a horizontal state, the lower module 2 is in a horizontal state, and the two ends of the upper module 1 and the lower module 2 near the connecting pipe 14 are both equipped with a rotating hinge 3. The upper module 1 is equipped with an upper mold lip 6 on the side away from the connecting pipe 14, and the lower module 2 is equipped with a lower mold lip 7 on the side away from the connecting pipe 14. The rotating hinge 3 helps to install the upper module 1 and the lower module 2.

[0034] A vertically positioned hydraulic cylinder 9 is installed in the middle of the upper surface of the upper module 1. The output rod of the hydraulic cylinder 9 points downward and passes through the corresponding position in the middle of the upper module 1. The lower end of the output rod of the hydraulic cylinder 9 is fixedly connected to the middle of the upper surface of the moving plate 10. The moving plate 10 is in a horizontal state. The hydraulic cylinder 9 helps to drive the moving plate 10 to move in the vertical direction. A matching limiting hole 13 is provided on the upper module 1 corresponding to the limiting rod 12. A first bolt 16 is threaded vertically between the middle of both ends of the upper module 1 and the lower module 2. The first bolts 16 are all in a vertical state. The first bolts 16 facilitate the installation and limiting of the upper module 1 and the lower module 2.

[0035] A matching mounting plate 15 is fixedly installed on the end surface of the connecting pipe 14 away from the lower module 2. A matching sealing gasket 18 is fixedly installed on the side surface of the mounting plate 15 away from the connecting pipe 14. The sealing gasket 18 facilitates the sealing between the mounting plate 15 and the external pipe to be installed. Second bolts 17 are threaded horizontally into the center of the perimeter of the mounting plate 15. The second bolts 17 are all horizontal and penetrate the two sides of the sealing gasket 18 at the corresponding positions. The second bolts 17 help to install and limit the mounting plate 15.

[0036] The working principle of this utility model is as follows: During use, the lower surface of the lower module 2 is placed stably in the position where it is to be used. The lower module 2 can support and limit the various components assembled on the lower module 2, which helps to stably use the various components assembled on the lower module 2. The lower module 2 can support and limit the upper module 1 and the various components assembled on the upper module 1 by rotating the hinge 3 and the first bolt 16, which facilitates the stable use of the upper module 1 and the various components assembled on the upper module 1.

[0037] The side of the sealing gasket 18 furthest from the mounting plate 15 is aligned with the external pipe to be assembled. The mounting plate 15 and the sealing gasket 18 are then installed with the external pipe using the second bolt 17. The second bolt 17 can limit the distance between the mounting plate 15 and the external pipe to be assembled, and the sealing gasket 18 can seal the distance between the mounting plate 15 and the external pipe to be installed, thus preventing leakage between the mounting plate 15 and the external pipe.

[0038] External pipes can deliver coating material to the second retention groove 5 on the lower module 2 and the first retention groove 4 on the upper module 1 through the sealing gasket 18, mounting plate 15, connecting pipe 14 and through hole 8 on the lower module 2. When it is necessary to adjust the cavity pressure in the first retention groove 4 on the upper module 1 and the second retention groove 5 on the lower module 2, the hydraulic cylinder 9 on the upper surface of the upper module 1 is opened. When the hydraulic cylinder 9 is opened, the output rod of the hydraulic cylinder 9 can drive the moving plate 10 and the sealing frame 11 to move vertically. The sealing frame 11 can seal between the moving plate 10 and the first retention groove 4 on the upper module 1. When the moving plate 10 moves vertically, it can drive the limiting rod 12 to move vertically along the limiting hole 13 on the upper module 1. The upper module 1 can limit the moving plate 10 through the limiting hole 13 and the limiting rod 12, which helps to move the moving plate 10 stably.

[0039] By adjusting the vertical movement of the moving plate 10 and the sealing frame 11, the size of the space located below the moving plate 10 and the sealing frame 11 in the first retention groove 4 on the upper module 1 can be adjusted. By adjusting the size of the space, the cavity pressure below the moving plate 10 and the sealing frame 11 in the first retention groove 4 on the upper module 1 can be adjusted, as well as the cavity pressure in the second retention groove 5 on the lower module 2, so as to ensure that the cavity pressure is stable within a suitable range, thereby achieving high-quality coating operation. When it is necessary to flip and open the upper module 1 and the lower module 2, the first bolt 16 is rotated and removed, so that the first bolt 16 no longer limits the upper module 1 and the lower module 2. Furthermore, the upper module 1 is flipped and opened along the lower module 2 by rotating the hinge 3, so as to facilitate the opening process between the upper module 1 and the lower module 2.

[0040] During use, when facing different coating materials, different coating thickness requirements, and complex coating conditions, this coating die head can easily adjust the cavity pressure and ensure the accuracy of the cavity pressure adjustment. This helps to ensure the stability of the coating die head in processing products, thereby reducing the scrap rate and improving the efficiency of the coating die head in processing products.
