[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figures 1-6 As shown, this utility model provides a technical solution: an auxiliary tooling for quick installation and testing of airtightness, including an upper mold plate 1 and a lower mold plate 2. The upper mold plate 1 and the lower mold plate 2 have an upper mold pressing core 10 adapted to the upper contour of the product to be inspected 3 and a lower mold pressing core 20 adapted to the lower contour of the product to be inspected 3 on their opposite surfaces. The upper mold pressing core 10 has a cavity 100, and the inner contour of the cavity 100 is adapted to the raised colloid 30 of the upper contour of the product to be inspected 3. The upper mold plate 1 is driven to abut against the lower mold plate 2. The upper mold pressing core 10 and the lower mold pressing core 20 jointly press the product to be inspected 3. The upper mold pressing core 10 and the lower mold pressing core 20 form a pressing structure that can press the product to be inspected 3 from all directions and place it flat, which solves the problem of uneven pressing surface causing local thin sheet warping, which affects the accuracy of subsequent airtightness testing. Furthermore, since a cavity 100 is opened within the upper mold pressing core 10, the upper mold pressing core 10 descends and presses against the lower mold pressing core 20. The cavity 100 completely covers the raised colloid 30 of the product to be inspected 3. The highest surface of the raised colloid 30 is in sealed contact with the bottom surface of the cavity 100, forming a sealed cavity. It should be noted that the upper mold plate 1 is pre-installed with a pneumatic pipe, which connects to the cavity 100 and enters the sealed cavity. By introducing air pressure into the sealed cavity and observing the change in air pressure inside the sealed cavity, the presence of air holes inside the raised colloid 30 on the product to be inspected can be tested.

[0023] In this embodiment, the pressing surfaces of the upper mold pressing core 10 and the lower mold pressing core 20 are provided with soft rubber pads. By providing soft rubber pads, it is prevented that when the upper mold pressing core 10 and the lower mold pressing core 20 exert force on the product to be inspected, indentations will be pressed out on the surface contour of the product to be inspected, affecting the appearance of the product.

[0024] See Figures 2-5 As shown, in this embodiment, a guide post 4 connects the upper mold plate 1 and the lower mold plate 2. The guide post 4 guides the upper mold plate 1 and the lower mold plate 2. In addition, a linear bearing 6 is embedded in the lower mold plate 2 at the position corresponding to the guide post 4. The lower end of the guide post 4 is connected to the linear bearing 6 to reduce the coefficient of friction and improve the accuracy and stability of the movement. A return spring 5 is sleeved on the outside of the guide post 4, which provides a reverse force for the upper mold plate 1 to disengage from the lower mold plate 2.

[0025] SeeFigure 2 As shown, in this embodiment, a fixing pin 7 is connected to the bottom of the lower molding plate 2. The fixing pin 7 passes through the lower molding plate 2 and is threadedly connected to the guide post 4. A gasket 8 is connected in series outside the fixing pin 7. The gasket 8 is attached to the bottom of the linear bearing 6 through the fixing pin 7.

[0026] See Figure 6 As shown, in this embodiment, a lower mold pad 9 is also provided at the lower part of the lower mold plate 2. The lower mold pad 9 is fixedly connected to the lower part of the lower mold plate 2 by a connecting pin.

[0027] Working Principle: During use, the product to be inspected 3 is placed on the lower die pressing core 20 of the lower die platen 2. The upper die platen 1, driven by the pressing machine, abuts against the lower die platen 2. The upper die pressing core 10 and the lower die pressing core 20 together press the product to be inspected 3, ensuring that the product to be inspected 3 is pressed in all directions and placed flat. The upper die pressing core 10 moves downwards to press against the lower die pressing core 20. The cavity 100 inside the upper die pressing core 10 completely covers the raised colloid 30 of the product to be inspected 3. The highest surface of the raised colloid 30 is in sealed contact with the bottom surface of the cavity 100, forming a sealed cavity. By introducing air pressure into the sealed cavity, the change in air pressure inside the sealed cavity is observed to test whether there are air holes inside the raised colloid 30 on the product to be inspected 3.
