Description

Technical Field

[0001] This invention relates to the field of tailgate cover airtightness testing technology, specifically to an airtightness testing device for tailgate cover processing. Background Technology

[0002] The tailgate cover is a decorative and soundproofing component used to ensure the flatness and consistent layout of the tailgate. Before use, the tailgate cover is usually tested for its sealing performance to prevent leakage. The watertight method is commonly used to test the sealing performance. This method involves submerging an object in water and observing the air bubbles. However, because multiple tests are performed, the mold is opened and closed repeatedly. This repeated opening and closing causes wear on the sealing structure inside the mold. Wear on the sealing structure can lead to false readings in the water, reducing the accuracy of the test and affecting the equipment's usability.

[0003] Based on this, the present invention designs an airtightness testing device for tailgate cover processing to solve the above problems. Summary of the Invention

[0025] Please see Figure 1-5 The present invention provides a technical solution:

[0026] An airtightness testing device for tailgate cover processing includes a housing 1, a guide rod 2 fixedly connected to the housing 1, the guide rod 2 being hollow inside, a high-pressure pump 3 installed inside the housing 1, the output end of the high-pressure pump 3 fixedly connected to the guide rod 2, a lower mold 4 installed at one end of the guide rod 2, four first hydraulic rods 6 installed on the bottom surface of the inner wall of the housing 1, a water tank 7 installed between the four first hydraulic rods 6, the water tank 7 being slidably connected to the guide rod 2, a first cavity 10 opened inside the lower mold 4, four first springs 11 fixedly connected to the bottom surface of the inner wall of the first cavity 10, and a sealing gasket 12 installed between the four first springs 11. The inner wall of the first cavity 10 has four pairs of second cavities 13. Two second springs 14 are fixedly connected to one side of the inner wall of the second cavity 13. A compression block 15 is installed between the two second springs 14. A rotating column 16 is rotatably connected inside the second cavity 13. An adjusting plate 17 is installed on the rotating column 16. A sealing block 18 is installed on the adjusting plate 17. Four support rods 20 are fixedly connected to the outer shell 1. A top plate 21 is installed between the four support rods 20. A second hydraulic rod 22 is installed on the top plate 21. An upper mold 23 is installed at one end of the second hydraulic rod 22. A clamping block 24 is installed on the upper mold 23.

[0027] The outer shell 1 has multiple water-permeable holes 5 located on the upper side of the water tank 7. A sealing ring 8 is provided between the water tank 7 and the guide rod 2. A protective plate 9 is installed between the two first hydraulic rods 6. The protective plate 9 is slidably connected inside the outer shell 1. A groove is provided on the sealing gasket 12. The locking block 24 is movably connected in the groove. A transparent glass layer is provided between every two support rods 20 to facilitate the liquid to quickly envelop the upper mold 23 and the lower mold 4.

[0028] The four first springs 11 are located at the four corners of the bottom surface of the inner wall of the first cavity 10, which helps to improve the stability of the sealing gasket 12.

[0029] Among them, the four pairs of second cavities 13 are arranged in a ring, and the four pairs of second cavities 13 are located on the inner wall of the first cavity 10 respectively. The second cavities 13 are N-shaped, which facilitates the sliding of the extrusion block 15 and facilitates the sealing block 18 to seal the card block 24.

[0030] Two extrusion blocks 15 are installed opposite each other. The surface of the extrusion block 15 is arc-shaped. The surface of the sealing block 18 is provided with a flexible rubber layer. One end of the adjusting plate 17 is movably connected to the extrusion block 15, which facilitates the improvement of the stability of the equipment.

[0031] The locking block 24 is wedge-shaped and is movably connected in the first cavity 10. The lower mold 4 has four positioning holes 19 and the upper mold 23 has four positioning pins 25, which are movably connected in the positioning holes 19 to facilitate the movement and sealing of the sealing block 18.

[0032] The top plate 21 is equipped with a controller 26, and the front of the outer casing 1 is rotatably connected to two cabinet doors 27. Each cabinet door 27 is equipped with a handle 28, and the surface of the handle 28 is covered with a rubber anti-slip layer to facilitate equipment maintenance.

[0033] The bottom surface of the outer casing 1 is equipped with four bases 29, which are located at the four corners of the bottom surface of the outer casing 1; this helps to improve the stability of the equipment.

[0034] Working principle:

[0035] The part to be inspected is placed in the lower mold 4. The second hydraulic rod 22 is then lowered, causing the upper mold 23 to move downwards. As the upper mold 23 moves, its positioning pin 25 is positioned within the positioning hole 19. With the continued downward movement of the upper mold 23, the locking block 24 on the upper mold 23 first passes two sealing blocks 18, then passes the pressing block 15. When the locking block 24 passes the pressing block 15, because it is wedge-shaped, it continuously pushes the two pressing blocks 15 backwards. At this time, the second spring 14 is compressed, while one end of the locking block 24 is located within the sealing gasket 12, continuously compressing the first spring 11. When the locking block 24 compresses the two pressing blocks 18... At 5 o'clock, the extrusion block 15 simultaneously pushes the adjustment plate 17, causing the adjustment plate 17 to rotate around the rotating column 16 as the fulcrum. As the upper mold 23 continues to press down, the cooperation between the clamping block 24 and the extrusion block 15 makes the distance between the sealing block 18 and the clamping block 24 get closer and closer, thereby clamping and sealing the clamping block 24 on both sides. When the upper mold 23 moves to the appropriate position, the first hydraulic rod 6 is opened, causing the first hydraulic rod 6 to drive the water tank 7 to move upward. When the water tank 7 moves to the appropriate position, both the upper mold 23 and the lower mold 4 are located in the water tank 7. As the first hydraulic rod 6 moves upward, the protective plate 9 seals and protects the front side of the equipment. Then, the high-pressure pump 3 is turned on, causing the high-pressure pump 3 to fill the guide rod 2 with high pressure. At this time, the airtightness of the equipment can be observed through the liquid in the water tank 7.

[0036] The upper mold 23 and lower mold 4 in the equipment cooperate to effectively seal the material, thereby performing airtightness testing. The cooperation of the extrusion block 15, the second spring 14, the adjusting plate 17, and the sealing block 18 in the equipment allows the equipment to change its position as the upper mold 23 moves during sealing, making the equipment more stable during sealing. This avoids repeated friction from repeated use, which could reduce the sealing performance of the equipment. It also prevents the upper mold 23 and lower mold 4 from changing their sealing performance due to thermal expansion and contraction when located in the water tank 7, which could lead to false tests during sealing. Furthermore, the cooperation of the first spring 11 and the sealing gasket 12 in the equipment ensures a closer fit during sealing, further guaranteeing the accuracy of the equipment's testing.
