Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figures 1 to 2 , an embodiment provided by the present invention: It includes an underframe 1, and the underframe 1 is made of strong and durable steel, which can provide stable support for the entire device. The bottom of the underframe 1 is fixedly connected with a connecting plate 2. The connecting plate 2 plays a role in connecting various components, and its material is high-strength alloy to ensure the firmness of the connection. The bottom of the connecting plate 2 is fixedly connected with a floating mechanism 3. The floating mechanism 3 can make the outer contour upper die 5 move flexibly within a certain range, improving the adaptability of the device and effectively ensuring accurate cooperation with the outer contour lower die 13 under different working conditions.

[0023] The bottom of the floating mechanism 3 is slidably connected with an outer contour upper die 5. The outer contour upper die 5 is made of high-quality aluminum alloy, which has good strength and wear resistance and can accurately cooperate with the outer contour lower die 13 to ensure the sealing effect. An inflating structure is arranged on one side of the outer contour upper die 5. The inflating structure includes an air pipe joint 7. The air pipe joint 7 is made of rubber with good sealing performance to ensure that there is no leakage during gas transmission. The right side of the pipe joint is fixedly connected with an inflatable tube orifice 6. The inflatable tube orifice 6 can quickly connect to the air source to provide stable air pressure between the outer contour upper die 5 and the outer contour lower die 13.

[0024] A sealing ring 12 is detachably connected to the bottom of the outer contour upper die 5. The sealing ring 12 is made of rubber material with good elasticity and can closely fit between the outer contour upper die 5 and the outer contour lower die 13, effectively preventing gas leakage and greatly improving the sealing performance. The bottom of the sealing ring 12 is detachably connected to the outer contour lower die 13. The outer contour lower die 13 is also made of high-quality aluminum alloy and precisely matches with the outer contour upper die 5, providing a stable environment for the test of the product 25. A connecting block 10 is fixedly connected inside the outer contour lower die 13. The connecting block 10 is made of solid metal material to ensure the stability of connection with other components.

[0025] A inner end interface 11 is fixedly connected to the right side of the connecting block 10. The inner end interface 11 is reasonably designed and can be conveniently connected to the sealing joint 14 to ensure smooth gas transmission. An adjusting structure is fixedly connected to the top right of the connecting block 10. The adjusting structure includes a CAN communication joint 9. The CAN communication joint 9 can achieve precise signal transmission to ensure accurate adjustment of the adjusting plate 8. The CAN communication joint 9 is rotatably connected to an adjusting plate 8 on the right side. The adjusting plate 8 can flexibly adjust the air pressure according to actual needs, improving the adaptability of the device and the accuracy of the test. A sealing joint 14 is detachably connected to the right side of the inner end interface 11. The sealing joint 14 is made of high-quality sealing material and can be closely connected to the inner end interface 11 to prevent gas leakage.

[0027] A peripheral airtight groove 15 is provided at the top of the product 25. The peripheral airtight groove 15 is detachably connected to the bottom of the outer contour lower die 13. The design of the peripheral airtight groove 15 can better cooperate with the outer contour lower die 13 to ensure the sealing performance of the product 25 during the test. A PU buffer pad 4 is fixedly connected to the bottom of the connecting plate. The PU buffer pad 4 has good buffering performance and can reduce the vibration during the operation of the device, protecting each component from damage. A pressure head 18 is slidably connected inside the connecting plate 2. The pressure head 18 is made of high-strength steel and can stably move driven by the cylinder to achieve air pressure change.

[0028] On the right top of the chassis 1, there is a fixedly connected connection port 20. The connection port 20 is made of a strong material and can be stably connected to the up-and-down shaft 21. Inside the connection port 20, there is a slidably connected up-and-down shaft 21, and the up-and-down shaft 21 can smoothly slide within the connection port 20 to achieve the up-and-down movement of the pressing plate 22. At the top of the up-and-down shaft 21, there is a fixedly connected pressing plate 22. The pressing plate 22 is made of a high-strength material and can withstand a certain pressure to ensure the stable operation of the device. The bottom of the lower shaft is fixedly connected to the four corners of the connecting plate 2, and the connection between the up-and-down shaft 21 and the connecting plate 2 is firm, capable of stably transmitting power.

[0029] Inside the pressing plate 22, there is a fixedly connected support 23. The support 23 provides additional support for the device and enhances the stability of the device. On the left side of the chassis 1, there is a fixedly connected support frame 24. The support frame 24 can provide auxiliary support for the chassis 1 and improve the stability of the entire device. There is a gap between the chassis 1 and the connecting plate 2. This gap is reasonably designed, which can provide a certain space for the operation of the device and is also convenient for installation and maintenance. At the bottom of the connecting plate 2, there is a fixedly connected PU buffer pad 4. The PU buffer pad 4 plays a buffering role again to further protect the various components of the device.

[0030] Working principle: When the staff needs to conduct a test, at this time, connect the sealing joint 14 to the inner end interface 11. Through the surrounding airtight groove, it can be hermetically connected to the outer contour lower mold. At this time, connect the outer contour upper mold 5 to the outer contour lower mold 13, and use the sealing ring 12 to seal it to ensure that the upper and lower molds will not leak. At this time, input air through the air inlet pipe 6, and input the air into the inside of the outer contour upper mold 5 and the outer contour lower mold 13 through the air pipe joint 7.

[0031] When the mechanism operates, the air cylinder can drive the pressure head to move, so that the pressure head can drive the air pressure to change. Through the adjustment plate, the air pressure is adjusted to change. When the air pressure changes, the airtightness of the sealing joint 11 can be detected, and at the same time, the airtightness of the product's surrounding airtight groove can be detected.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
