[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. After the rubber seals at the first workstation are processed, the operator can take out the finished product and put in a new semi-finished rubber seal to be processed.

[0016] 4. When the electric heating element is connected to the power supply, electrical energy is converted into heat energy, and the electric heating element heats up rapidly. Since the heating oil chamber is filled with heating oil, the heated electric heating element transfers heat to the heating oil. The heating oil has good thermal conductivity and can quickly absorb the heat from the electric heating element and diffuse it evenly inside the heating oil chamber, so that the temperature of the entire heating oil chamber remains consistent. In this way, the upper and lower molds surrounding the heating oil chamber can be heated evenly, providing a stable and suitable temperature environment for the hot vulcanization of the rubber seals, ensuring that the rubber seals can be fully vulcanized and achieve the required performance indicators.

[0023] 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.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4In this embodiment of the present invention, a rubber seal heat-bonding vulcanization mold includes a heat-bonding vulcanization device 1. The heat-bonding vulcanization device 1 consists of a bracket 2 and a mounting frame 6. The mounting frame 6 is installed at the middle of the upper end of the bracket 2. A moving mechanism 3 is installed in the middle of the bracket 2. A moving platform 19 is installed at the upper end of the moving mechanism 3. Two lower molds 5 are installed on the upper side of the moving platform 19. A lower mold core 12 is installed on the upper side of the lower molds 5. Telescopic rods 7 are installed on both sides of the upper end of the mounting frame 6. An upper mold 11 is installed at the bottom of the telescopic rods 7. An upper mold core 18 is installed at the bottom of the upper mold 11. A limiting mechanism 8 is provided between the two sides of the upper mold 11 and the mounting frame 6. A heating oil cavity 20 is provided between the upper mold 11 and the lower molds 5. The heating oil cavity 20 is filled with heating oil. A heating mechanism 22 is installed inside the heating oil cavity 20.

[0025] The limiting mechanism 8 consists of limiting grooves 9 and pins 10. Pins 10 are installed on both sides of the upper end of the upper mold 11. The limiting grooves 9 are located on both sides inside the mounting frame 6. Pins 10 are slidably installed inside the limiting grooves 9. When the telescopic rod 7 drives the upper mold 11 to move up and down, the pins 10 installed on both sides of the upper end of the upper mold 11 slide in the limiting grooves 9 on both sides inside the mounting frame 6. The limiting grooves 9 provide a precise moving track for the pins 10, ensuring that the upper mold 11 always maintains vertical movement during the up and down movement and will not shift or shake to the left or right. In this way, the upper mold core 18 at the bottom of the upper mold 11 can accurately align with the lower mold core 12, ensuring the sealing and stability between the upper mold 11 and the lower mold 5 during the hot vulcanization process of the rubber seal, and avoiding the failure of the rubber seal to be processed due to mold misalignment.

[0026] The moving mechanism 3 consists of a lead screw 13, a lead screw nut 17, and a power mechanism 16. The lead screw nut 17 is installed in the middle of the moving table 19, and the lead screw 13 is rotatably installed inside the lead screw nut 17. The lead screw 13 is rotatably installed in the middle of the bracket 2, and one end of the lead screw 13 passes through the bracket and is installed at the front end of the power mechanism 16. The power mechanism 16 is installed on one side of the bracket 2. After the power mechanism 16 is started, it drives the lead screw 13 to rotate. Since the lead screw nut 17 is installed in the middle of the moving table 19 and the lead screw 13 is rotatably installed inside the lead screw nut 17, the rotational motion of the lead screw 13 is converted into the linear motion of the lead screw nut 17, which in turn drives the moving table 19 to move horizontally in the middle of the bracket 2. By controlling the rotation direction and number of rotations of the lead screw 13, the position of the moving table 19 can be precisely adjusted so that the two lower molds 5 can be moved to the appropriate processing position and loading / unloading position, which is convenient for operators to operate and also ensures that the upper mold 11 and the lower mold 5 can be accurately aligned during processing.

[0027] The power mechanism 16 consists of an electric motor 15 and a gearbox 14. The gearbox 14 is mounted on one side of the bracket 2, and the electric motor 15 is mounted on the other side of the gearbox 14. The electric motor 15 serves as the power source, outputting high-speed rotational power. The power output by the electric motor 15 is first transmitted to the gearbox 14. The gearbox 14 adjusts the speed and torque of the electric motor 15 according to the actual processing requirements, and transmits the appropriate speed and torque power to the lead screw 13, so that the lead screw 13 drives the moving table 19 to move at an appropriate speed and force. This ensures that the moving table 19 can move quickly and stably to the designated position, and also meets the requirements of different processing techniques for moving speed and force, ensuring the smooth progress of the entire hot-welding vulcanization process.

[0028] The heating mechanism 22 consists of a mounting base 23 and an electric heating tube 21. The electric heating tube 21 is installed on one side of the mounting base 23, and the mounting base 23 is installed on one side of the heating oil chamber 20. The electric heating tube 21 extends into the heating oil chamber 20. When the electric heating tube 21 is connected to the power supply, electrical energy is converted into heat energy, and the electric heating tube 21 heats up rapidly. Since the heating oil chamber 20 is filled with heating oil, the heated electric heating tube 21 transfers heat to the heating oil. The heating oil has good thermal conductivity and can quickly absorb the heat from the electric heating tube 21 and diffuse it evenly inside the heating oil chamber 20, so that the temperature of the entire heating oil chamber 20 remains consistent. In this way, the upper mold 11 and the lower mold 5 surrounding the heating oil chamber 20 can be heated evenly, providing a stable and suitable temperature environment for the hot vulcanization of the rubber seal, ensuring that the rubber seal can be fully vulcanized and achieve the required performance indicators.

[0029] The bottom of the support 2 is provided with a holding platform 4, which is slidably connected to the moving platform 19. When the moving platform 19 moves horizontally, the holding platform 4 provides stable support and guidance for the moving platform 19.

[0030] The working principle and usage process of this utility model: The rubber seal heat-sealing vulcanization mold adopts a dual-station design, which greatly improves the processing efficiency. In the initial state, the two lower molds 5 on the moving table 19 are in the waiting state. The operator first places the semi-finished rubber seal to be processed on the lower mold core 12 of one of the lower molds 5. This is the first station. Then, the telescopic rods 7 on both sides of the upper end of the mounting frame 6 are activated, which drives the upper mold 11 to move downward. The upper mold core 18 at the bottom of the upper mold 11 and the lower mold core 12 are precisely matched to seal the semi-finished rubber seal in the space formed between the upper mold 11 and the lower mold (5). At the same time, the other The second station of the lower mold 5 allows operators to load and unload materials. After the upper mold 11 and the lower mold 5 are closed, the heating mechanism 22 inside the heating oil chamber 20 starts working. After the heating oil absorbs heat, it evenly transfers the heat energy to the mold, causing the rubber seal to undergo a vulcanization reaction under high temperature and high pressure, completing the heat connection process. After the rubber seal at the first station is processed, the telescopic rod 7 drives the upper mold 11 to rise, and the operator can take out the finished product and put in a new semi-finished rubber seal to be processed. At this time, the second station begins the vulcanization process. This cycle repeats, realizing an efficient operation mode of loading and unloading materials while processing.

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
