Description

Technical Field

[0001] This utility model relates to the field of mold pressure testing technology, and more specifically, to a tire mold pressure testing device. Background Technology

[0002] Tire molds are molds used for vulcanizing and forming various types of tires. As an important tool in tire production, the quality and performance of tire molds are directly related to the quality of tires and production efficiency. Before leaving the factory and during use in the tire factory, tire molds need to be pressure tested to ensure high precision requirements, and the molds need to be repaired based on the test results.

[0003] However, existing tire mold testing uses a specific type of testing device, which is not convenient for pressure testing of multiple types of molds, making the operation cumbersome when testing multiple tire molds.

[0004] A search revealed that Chinese patent CN218121379U discloses a tire mold pressure testing device. This structure utilizes a conveyor belt to transport the mold, an electric push rod to drive clamping plates, and anti-slip pads on both sides of the clamping plates to ensure stable fixation and prevent slippage and wear. It can also adapt to molds of different sizes, facilitating testing. Furthermore, the support platform supports the bottom of the conveyor belt, promoting stable transport, facilitating batch testing, and saving manpower. A hydraulic controller controls a hydraulic pump, which, through a balance bar, sliding sleeve, and support column, causes the pressure plate to rise and fall vertically. The hydraulic pump pushes the pressure plate from the middle to achieve uniform pressure application. A pressure sensor detects the pressure, and the pressure controller sets the test pressure to ensure stable and accurate pressure testing. It is adaptable to molds of various specifications and structures.

[0005] However, in actual use, although the sliding fit between the sliding sleeve and the support column can ensure the vertical sliding of the balance bar, during long-term use, friction may cause wear between the sliding sleeve and the support column, resulting in an increased fit clearance. This affects the accuracy of the vertical lifting and lowering of the pressure plate, causing uneven pressure on the mold and affecting the test results. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tire mold pressure testing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A tire mold pressure testing device includes a support platform, a conveyor belt installed on one side of the support platform, a fixed plate fixedly installed on one side of the support platform, a fixed frame fixedly installed on the top of the support platform, and a guide mechanism installed inside the fixed frame.

[0009] The guiding mechanism includes multiple guide grooves formed inside the fixed frame. A guide box is slidably disposed inside the guide groove. A through hole is formed on the surface of the guide box. A guide rod is slidably disposed inside the through hole. A fixed cylinder is fixedly disposed inside the guide box. A multiple hole is formed on the surface of the fixed cylinder. A sponge layer is fixedly disposed on one side of the fixed cylinder.

[0010] By adopting the above technical solution, it is possible to ensure that the pressure-applying components move vertically, making the pressure on the tire mold more stable and accurate. It can also lubricate the guide rod, reduce frictional resistance, ensure smooth operation of the device, extend its service life, and provide stable and reliable guiding support for tire mold pressure testing, which helps to improve the testing accuracy and the stability of the device.

[0011] As a further description of the above technical solution: the sponge layer is in contact with the guide rod, a liquid inlet pipe is provided through the surface of the guide box, a sealing cap is threaded to one end of the liquid inlet pipe, a first electric telescopic rod is fixedly provided on one side of the fixed frame, a pressure plate is fixedly provided at the output end of the first electric telescopic rod, and the pressure plate is connected to the guide box on all four sides.

[0012] By adopting the above technical solution—the combination of the inlet pipe, the sealing cap, and the sponge layer—lubricant can be easily injected while ensuring the reliability of the pressure test process.

[0013] As a further description of the above technical solution: A fixing mechanism is provided on one side of the support platform. The fixing mechanism includes a U-shaped frame fixedly installed on one side of the support platform. A second electric telescopic rod is fixedly installed on one side of the U-shaped frame. A movable plate is fixedly installed on one side of the second electric telescopic rod. An installation groove is opened on the surface of the movable plate. A T-shaped strip is inserted into the inside of the installation groove. A clamping plate is fixedly installed on one side of the T-shaped strip. A rubber layer is fixedly installed on the surface of the clamping plate.

[0014] The surface of the movable plate is provided with a sliding groove, and a slide bar is slidably arranged inside the sliding groove. A protrusion is fixedly arranged on one side of the slide bar. Both the protrusion and the surface of the movable plate are provided with threaded holes, and bolts are threaded into the internal threads of the threaded holes.

[0015] By adopting the above technical solution, the mold can be quickly clamped and released, which is convenient to operate and improves the testing efficiency. The rubber layer on the surface of the clamping plate increases the friction with the mold surface, which can not only firmly fix the mold and prevent the mold from sliding or displacing during the test, but also protect the mold surface from damage, thus improving the versatility and practicality of the device.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. By setting up a guiding mechanism, the lubrication design is ingenious compared with the existing technology. Lubricating fluid is injected through the inlet pipe, penetrates into the sponge layer through the holes of the fixed cylinder, and then is transmitted to the guide rod. This effectively reduces the frictional resistance when the guide rod slides, ensuring smooth operation of the device and extending its service life. The conveyor belt accurately transports the tire mold to the initial test position on the fixed plate, which facilitates subsequent test operations, improves test efficiency, and ensures stable and accurate pressure application. The first electric telescopic rod pushes the pressure plate, and the guide box and guide rod cooperate to ensure that the pressure plate moves vertically downward, which can apply pressure evenly to the tire mold. By controlling the telescopic rod's extension and contraction, different pressure values ​​can be tested, providing a reliable basis for tire mold quality inspection.

[0018] 2. By setting up a fixing mechanism, compared with the existing technology, the second electric telescopic rod drives the moving plate and clamping plate. The rubber layer is non-slip and protects the mold, which can firmly clamp the mold and prevent sliding displacement during testing, ensuring test accuracy. The first electric telescopic rod pushes the pressure plate, and the guide box cooperates with the guide rod to make the pressure plate move vertically downward, ensuring stable and accurate pressure on the mold and improving test accuracy. The clamping plate replacement design is ingenious. By unscrewing the bolts, the moving slide releases the limit on the T-shaped strip, and the clamping plate can be easily pulled out. The operation is simple, which is conducive to maintenance and replacement of worn parts, reduces maintenance costs, improves the applicability and service life of the device, and ensures long-term stable operation of the device.

[0026] 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.

[0027] The embodiments disclosed in this application are as follows: Figure 1-6 The tire mold pressure testing device shown includes a support platform 1, a conveyor belt 2 installed on one side of the support platform 1, a fixing plate 3 fixedly installed on one side of the support platform 1, a fixing frame 4 fixedly installed on the top of the support platform 1, and a guide mechanism installed inside the fixing frame 4.

[0028] The guiding mechanism includes multiple guide grooves 5 inside the fixed frame 4, a guide box 6 is slidably arranged inside the guide groove 5, a through hole 7 is opened on the surface of the guide box 6, a guide rod 8 is slidably arranged inside the through hole 7, a fixed cylinder 9 is fixedly arranged inside the guide box 6, a multiple hole is opened on the surface of the fixed cylinder 9, and a sponge layer 10 is fixedly arranged on one side of the fixed cylinder 9.

[0029] Open the sealing cap 12 on the liquid inlet pipe 11 and inject an appropriate amount of lubricant into the guide box 6 through the liquid inlet pipe 11. After the lubricant enters the guide box 6, it will penetrate into the sponge layer 10 through the holes on the surface of the fixed cylinder 9. Since the sponge layer 10 is in contact with the guide rod 8, the lubricant will be transferred to the surface of the guide rod 8 to provide lubrication for the subsequent sliding of the guide rod 8 and reduce frictional resistance.

[0030] Then the tire mold to be tested is placed on the conveyor belt 2, and the conveyor belt 2 starts to run, transporting the tire mold towards the fixed plate 3 on one side of the support platform 1. When the tire mold is transported to the fixed plate 3, the conveyor belt 2 stops working. At this time, the tire mold is in the initial position ready for pressure testing.

[0031] Reference Figure 2-4As shown, the sponge layer 10 is in contact with the guide rod 8, and the surface of the guide box 6 is provided with a liquid inlet pipe 11. One end of the liquid inlet pipe 11 is threaded with a sealing cap 12. A first electric telescopic rod 13 is fixedly provided on one side of the fixed frame 4. A pressure plate 14 is fixedly provided at the output end of the first electric telescopic rod 13. The pressure plate 14 is connected to the guide box 6 on all four sides.

[0032] The first electric telescopic rod 13 on one side of the fixed frame 4 is activated, and its output end extends to push the pressure plate 14 downward. The pressure plate 14 is connected to the guide box 6 around its perimeter. When the pressure plate 14 moves downward, the guide box 6 slides in the guide groove 5, and at the same time, the guide rod 8 slides in the through hole 7 on the surface of the guide box 6. This ensures that the pressure plate 14 moves vertically downward, thus ensuring the stability and accuracy of applying pressure to the tire mold.

[0033] Reference Figure 4-6 As shown, a fixing mechanism is provided on one side of the support platform 1. The fixing mechanism includes a U-shaped frame 15 fixedly installed on one side of the support platform 1. A second electric telescopic rod 16 is fixedly installed on one side of the U-shaped frame 15. A movable plate 17 is fixedly installed on one side of the second electric telescopic rod 16. An installation groove is opened on the surface of the movable plate 17. A T-shaped strip 18 is inserted into the inside of the installation groove. A clamping plate 19 is fixedly installed on one side of the T-shaped strip 18. A rubber layer 20 is fixedly installed on the surface of the clamping plate 19.

[0034] The surface of the movable plate 17 is provided with a sliding groove, and a sliding strip 21 is slidably arranged inside the sliding groove. A protrusion 22 is fixedly arranged on one side of the sliding strip 21. Both the protrusion 22 and the surface of the movable plate 17 are provided with threaded holes, and bolts 23 are threadedly connected inside the threaded holes.

[0035] The fixing mechanism on one side of the support platform 1 starts to work. The second electric telescopic rod 16 in the fixing mechanism is activated and its output end begins to extend. As the second electric telescopic rod 16 extends, the moving plate 17 connected to it begins to move towards the tire mold. The T-shaped strip 18 installed on the surface of the moving plate 17 drives the clamping plate 19 to move closer to the tire mold. The rubber layer 20 on the surface of the clamping plate 19 contacts the surface of the tire mold, which plays the role of anti-slip and protecting the surface of the mold.

[0036] When the second electric telescopic rod 16 pushes the moving plate 17 to the appropriate position, the clamping plates 19 on both sides will firmly clamp and fix the tire mold, preventing the mold from sliding or shifting during the pressure test. When the clamping plate 19 needs to be replaced, unscrew the bolt 23, then move the slide bar 21, which will move the slide bar 21 in the groove opened on the surface of the moving plate 17, thereby moving the slide bar 21 to one side of the T-shaped bar 18, releasing the limit on the T-shaped bar 18, and then pull the clamping plate 19 outward, so that the T-shaped bar 18 on one side of the clamping plate 19 can be removed from the mounting groove opened on the surface of the moving plate 17.

[0037] Working principle of this utility model:

[0038] This utility model is a tire mold pressure testing device. When using the device, firstly, open the sealing cap 12 on the liquid inlet pipe 11, and inject an appropriate amount of lubricant into the guide box 6 through the liquid inlet pipe 11. After the lubricant enters the guide box 6, it will penetrate into the sponge layer 10 through the holes on the surface of the fixed cylinder 9. Since the sponge layer 10 is in contact with the guide rod 8, the lubricant will be transferred to the surface of the guide rod 8, providing lubrication for the subsequent sliding of the guide rod 8 and reducing frictional resistance.

[0039] Then the tire mold to be tested is placed on the conveyor belt 2, and the conveyor belt 2 starts to run, transporting the tire mold towards the fixed plate 3 on one side of the support platform 1. When the tire mold is transported to the fixed plate 3, the conveyor belt 2 stops working. At this time, the tire mold is in the initial position ready for pressure testing.

[0040] The fixing mechanism on one side of the support platform 1 starts to work. The second electric telescopic rod 16 in the fixing mechanism is activated and its output end begins to extend. As the second electric telescopic rod 16 extends, the moving plate 17 connected to it begins to move towards the tire mold. The T-shaped strip 18 installed on the surface of the moving plate 17 drives the clamping plate 19 to move closer to the tire mold. The rubber layer 20 on the surface of the clamping plate 19 contacts the surface of the tire mold, which plays the role of anti-slip and protecting the surface of the mold.

[0041] Once the second electric telescopic rod 16 pushes the moving plate 17 to the appropriate position, the clamping plates 19 on both sides will firmly clamp and fix the tire mold to prevent the mold from sliding or displacing during the pressure test.

[0042] Next, the first electric telescopic rod 13 on one side of the fixed frame 4 is activated, and its output end extends to push the pressure plate 14 downward. The pressure plate 14 is connected to the guide box 6 around its perimeter. When the pressure plate 14 moves downward, the guide box 6 slides in the guide groove 5, and at the same time, the guide rod 8 slides in the through hole 7 on the surface of the guide box 6. This ensures that the pressure plate 14 moves vertically downward, ensuring the stability and accuracy of applying pressure to the tire mold.

[0043] Then the pressure plate 14 continues to move downward, gradually applying pressure to the fixed tire mold. By controlling the extension and contraction of the first electric telescopic rod 13, different pressure values ​​can be tested.

[0044] After the pressure test is completed, the first electric telescopic rod 13 retracts, causing the pressure plate 14 to move upward and return to its initial position. At the same time, the guide box 6 and the guide rod 8 will also reset as the pressure plate 14 moves. The second electric telescopic rod 16 retracts, causing the moving plate 17 and the clamping plate 19 to move away from the tire mold, releasing the fixation on the tire mold. The conveyor belt 2 starts again, transporting the tested tire mold out of the support platform 1 for the next test.

[0045] When the clamping plate 19 needs to be replaced, unscrew the bolt 23, then move the slide bar 21, causing the slide bar 21 to move within the groove on the surface of the moving plate 17, thereby moving the slide bar 21 to one side of the T-shaped bar 18, releasing the limit on the T-shaped bar 18, and then pull the clamping plate 19 outward, causing the T-shaped bar 18 on one side of the clamping plate 19 to exit from the mounting groove on the surface of the moving plate 17.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
