[0025] The present invention will be further described below in conjunction with the embodiments.

[0026] The following examples are used to illustrate the present invention, but they cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions. Simple improvements to the method of the present invention under the premise of the concept of the present invention belong to the scope of protection claimed in the present invention.

[0027] like Figure 1-6 As shown, the present invention provides an airbag pressure-maintaining film-laminating device, comprising a lower mold 1 and an upper mold 2;

[0028] A first air-filled cavity 111 is formed on one side of the lower mold 1, a boss 112 is formed on the side of the lower mold 1 away from the first air-filled cavity 111, and a first through hole 113 is formed on the lower mold 1. The first through hole 113 is located outside the boss 112 and communicates with the first air-filled cavity 111;

[0029] A groove 22 corresponding to the boss 112 is formed on one side of the upper mold 2, and a second air-filled cavity 21 is formed on one side of the upper mold 2 away from the groove 23. A second through hole 221 is formed on the inner bottom surface of the air-filled cavity 21, and two ends of the second through hole 221 are respectively located inside the air-filled cavity 21 and the groove 22;

[0030] The outer contour circumference of the groove 22 is at least greater than the outer contour circumference of the boss 112 .

[0031] A lower mold cover plate 3 for closing the first inflatable cavity 111 is provided on one side of the lower mold 1 corresponding to the first inflatable cavity 111;

[0032] A side of the upper mold 2 corresponding to the second inflatable cavity 21 is provided with an upper mold cover plate 4 for closing the second cavity 21;

[0033] The lower mold cover plate 3 and the upper mold cover plate 4 are both provided with connection holes 5 for connecting with external inflation conduits to inflate the first inflation cavity 111 and the second inflation cavity 21 respectively.

[0034] During the lamination process, the product is placed on the boss 112, and the soft material is preliminarily coated on the product. Then, the upper mold 2 and the lower mold 2 are closed, and the connecting holes on the lower mold 1 and the upper mold 2 are respectively connected to the output pipes of the external inflation device. The first inflation cavity 111 and the second inflation cavity 21 are inflated with air through the external inflation device, so that the gas in the first inflation cavity 111 and the second inflation cavity 21 enters the groove 22 through the first perforation 113 and the second perforation 221, respectively, and acts on the soft material, so that the soft material is deformed and coated on the product, and the lamination work is completed.

[0035] In order to ensure the accuracy of the coating, reduce the rigid contact of the film material and ensure the safety of the coating, a soft material layer 8 is provided in the groove 22 and extends toward the outer edge of the upper mold 2 away from the second inflation cavity 21 .

[0036] Furthermore, during lamination, the gas in the groove 22 increases, and the pressure increases, so that the soft material layer 8 is compressed and deformed to contact the film material, and the film material is squeezed onto the product, completing the lamination work.

[0037] In order to ensure the stability and safety of the airbag pressure-maintaining coating device during use, a sealing groove 23 is provided on the outer side of the groove 22 .

[0038] Furthermore, a sealing groove 23 is opened on the outer side of the groove 22. When the upper mold 2 and the lower mold 1 are formed, the soft material layer 8 covers the sealing groove 23 and is squeezed into the sealing groove 23, thereby sealing the outer side of the groove 22 to prevent the gas in the second inflation cavity 21 from leaking, resulting in insufficient air pressure affecting the product coating.

[0039] In order to increase the gas flow, enhance the pressure on the soft material, and ensure the stable coating of the product, a plurality of first perforations 113 and a plurality of second perforations 221 are provided, and the plurality of first perforations 113 and the plurality of second perforations 221 are respectively distributed in the first inflatable cavity 111 and the second inflatable cavity 21 in a rectangular array.

[0040] In order to ensure the structural stability of the lower mold 1 , first fixing holes 7 for fixing the lower mold cover plate 3 to the lower mold 1 are provided on the lower mold 1 and the lower mold cover plate 3 .

[0041] Furthermore, by setting a first fixing hole 7 on the lower mold 1 and the lower mold cover plate 3 (the fixing hole can be a threaded hole, or a through hole on the lower mold cover plate 3 and a threaded hole on the lower mold 1); fixing the lower mold cover plate 3 to the lower mold 1 by bolts or screws, thereby sealing the first inflation cavity 111.

[0042] In order to ensure the stability of the structure of the upper mold 2 , the upper mold 2 and the upper mold cover plate 4 are both provided with second fixing holes 6 for fixing the upper mold cover plate 4 to the upper mold 2 .

[0043] Furthermore, the second fixing hole 6 has the same structure as the first fixing hole 7 , and the upper mold cover plate 4 is effectively fixed to the upper mold 2 by bolts or screws to cover the second inflation cavity 21 .

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
