[0030] By installing rectangular plate 321 on the outside of die core 32, hollow cylinder 322 is installed on rectangular plate 321, by also installing die guide post 331 on the outer surface of die cavity 33, die guide post 331 is moved downward while controlling die cavity 33 to move downward, die guide post 331 can be inserted into the inside of hollow cylinder 322, avoid misplacement of die cavity 33 and die core 32, guarantee the production effect to product.
[0031] In a preferred embodiment, the protection mechanism 4 comprises a safety light barrier 41, which is installed at the outer end of the protection frame 2. The safety light barrier 41 is usually composed of a transmitter and a receiver. The transmitter emits a set of infrared light, which forms an invisible light barrier. The infrared light is sent out in a specific frequency and sequence, usually a plurality of light beams arranged at equal intervals, forming a protection area with a certain width and height, so as to protect the workers and prevent them from being pinched.
[0032] In a preferred embodiment, the top of the protection frame 2 is stably installed with a lifting cylinder 5, the telescopic end of the lifting cylinder 5 is stably installed with a pressure sensor 6, and the telescopic end of the lifting cylinder 5 is also installed with a heat insulation plate 7. The bottom of the heat insulation plate 7 is fixedly installed with a mold cavity 33, and the heat insulation plate 7 is arranged below the pressure sensor 6. The device is installed with the heat insulation plate 7 and the pressure sensor 6 at the telescopic end of the lifting cylinder 5. The mold cavity 33 can be controlled to move downward, and the mold cavity 33 can be moved to the position of the mold core 32. As the mold cavity 33 continuously moves downward, it will be attached to the mold core 32. The pressure sensor 6 will detect the extrusion force on the mold core 32, which can prevent the product from being damaged due to excessive extrusion. In addition, the mold cavity 33 is also provided with a thermocouple 9 and a heating rod 10. The mold cavity 33 is arranged inside the protection frame 2, and a lighting lamp 11 is also installed inside the protection frame 2. The heating rod 10 is installed on the mold cavity 33, which can heat the inside of the mold cavity 33. In order to avoid the influence of heat on the pressure sensor 6, the heat insulation plate 7 is installed at the top of the mold cavity 33, which can protect the pressure sensor 6 and make the equipment work normally.
[0033] The outside of the mold core 32 is also provided with an adjusting block 8, which is used to prevent the mold core 32 from deviating and causing the deviation of the mold closing guide pillar 331, thereby improving the accuracy of the mechanism.
[0034] The device is stably installed with a positioning suction cup 12 on the mold core 32, and a jacking column 13 is installed at the telescopic end of the jacking member 311. The jacking column 13 penetrates the inside of the mold core 32 and is in sliding connection with the inside of the mold core 32. The positioning suction cup 12 is arranged in four and is installed at the top of the mold core 32. The mold cavity 33 can be stably installed on the mold core 32, and the jacking column 13 is arranged in the inside of the mold core 32 and is in sliding connection with the inside of the mold core 32. In actual operation, after the product is placed on the mold core 32 and processed, the jacking column 13 will be driven by the jacking member 311 to extend one end of the jacking column 13 out of the inside of the mold core 32, so as to jacking the product out of the inside of the mold core 32, which is convenient for taking down the product and using.
[0035] The main frame 1 is provided with a start-stop button 14.
[0036] Specifically, a safe and stable working process or working principle of the hot pressing tool is that the common hot pressing tool on the market has certain safety risks, for example, during the use of the control mold cavity 33 downward movement and the mold core 32, the mold cavity 33 is easy to loosen and dislocate during the downward movement, which affects the product precision and quality. Therefore, the device is designed to solve this problem.
[0037] The device uses the mold closing guide column 331 to be inserted into the hollow cylinder 322, which can limit the mold cavity 33, avoid the error of the mold cavity 33 and the mold core 32 during the mold closing, and the specific operation is that the operator first places the product on the mold core 32, and then starts the start-stop button 14. At this time, the extension end of the lifting cylinder 5 moves downward, and when the extension end of the lifting cylinder 5 extends, it will push the mold cavity 33 to move downward, and at the same time, the heating rod 10 starts to heat the mold cavity 33. The inside of the mold cavity 33 is heated, and the thermocouple 9 monitors the temperature inside the mold cavity 33 at all times during the heating process. When the set temperature is reached, the heating rod 10 can be controlled to stop heating.
[0038] With the continuous downward movement of the mold cavity 33, the mold closing guide column 331 will be inserted into the inside of the hollow cylinder 322, and the mold closing guide column 331 will be closed, so as to ensure that the mold cavity 33 can be aligned with the mold core 32, and the mold cavity 33 and the mold core 32 are closed, which improves the processing effect of the product.
[0039] And through the pressure sensor 6, the pressure value of the tire membrane jig 31 can be detected, and when the set pressure is reached, the lifting cylinder 5 stops working, and the mold cavity 33 stops descending, so that the mold cavity 33 and the mold core 32 are pressed together, and the product is processed. After the hot pressing operation of the product processing is completed, the extension end of the lifting cylinder 5 is retracted, and the mold cavity 33 is moved upward, and then the extension end of the jacking piece 311 pushes the jacking column 13 to move upward, so as to push the product pressed together from the inside of the mold core 32, which is convenient for taking out the product and completing the processing operation.
