[0007] Preferably, the guiding mechanism consists of a guide rod and a guide groove. The guide groove is disposed around the upper end of the pressure plate, and the guide rod is welded to the upper end of the upper heating template. The guide rod is slidably installed inside the guide groove.

[0008] Preferably, the positioning mechanism consists of a positioning rod and a positioning groove. The positioning rod is welded to the bottom perimeter of the upper heating template, and the positioning groove is set around the upper perimeter of the lower heating template. The bottom end of the positioning rod is inserted into the positioning groove.

[0009] Preferably, the sliding mechanism consists of a sliding groove and a sliding foot. The sliding foot is welded to the bottom end of the first mounting plate, the sliding groove is disposed on the upper side of the worktable, and the sliding foot is slidably installed inside the sliding groove.

[0010] Preferably, the fine-tuning mechanism consists of a movable rod and a spring. The movable rod is installed on both longitudinal sides of the bottom heating template and both transverse sides of the second mounting plate. The movable rod is slidably installed on both transverse sides of the second mounting plate and both transverse sides of the first mounting plate. The spring is installed on the outside of the movable rod.

[0011] Preferably, a damping sleeve is slidably mounted on the outer side of the movable rod, and the damping sleeve is installed on both longitudinal sides of the second mounting plate or both transverse sides of the first mounting plate.

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

[0013] 1. Throughout the process, the guiding mechanism, positioning mechanism, sliding mechanism and fine-tuning mechanism work together to ensure precise alignment of the upper and lower templates and prevent misalignment, so that the rubber can be heated and compressed evenly during vulcanization, thus ensuring vulcanization quality.

[0014] 2. As the upper heating template moves down close to the lower heating template, the positioning rods welded to the bottom perimeter of the upper heating template gradually align with the positioning grooves on the upper perimeter of the lower heating template. As the upper heating template continues to move down, the bottom of the positioning rods inserts into the positioning grooves. Through this interlocking method, the relative positions of the upper and lower heating templates are further precisely determined, achieving accurate positioning of the upper and lower templates. Even if subjected to certain external forces during vulcanization, the cooperation between the positioning rods and the positioning grooves can limit the relative movement of the templates, prevent misalignment, and ensure the accuracy and consistency of rubber vulcanization.

[0015] 3. The sliding foot welded to the bottom of the first mounting plate can slide in the groove of the workbench. When the bottom heating template is introduced, the telescopic rod pushes the first mounting plate. At this time, the sliding foot slides in the groove, providing smooth guidance and support for the movement of the first mounting plate. Through this sliding connection, the bottom heating template can be easily moved to the position corresponding to the upper heating template. At the same time, the bottom heating template can be exported during use for easy material discharge.

[0016] 4. Movable rods installed on both sides of the bottom heating template in the longitudinal direction and on both sides of the second mounting plate in the transverse direction can slide on both sides of the second mounting plate and on both sides of the first mounting plate in the transverse direction. When the positioning rods around the bottom of the upper heating template have a slight deviation during the alignment process, the movable rods can move slightly within their installation positions. The springs installed on the outside of the movable rods will generate elastic force to buffer and reset the movement of the movable rods, so that the bottom heating template can automatically adjust its position within a certain range to compensate for the slight deviation.

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 4 In this embodiment of the utility model, a rubber vulcanizing machine mold anti-misalignment device includes a vulcanizing mold 1; the vulcanizing mold 1 consists of a workbench 2 and a support 3, the bottom end of the support 3 is installed on the upper side of the workbench 2, a hydraulic cylinder 5 is installed on the upper side of the support 3, a pressure plate 7 is installed at the bottom end of the hydraulic cylinder 5, an upper heating template 8 is provided at the bottom end of the pressure plate 7, a guide mechanism 6 is installed between the upper end of the upper heating template 8 and the pressure plate 7, a first mounting plate 15 is provided at the upper end of the workbench 2, and the bottom end of the first mounting plate 15 is connected to the workbench 2 through a sliding mechanism 12. The first mounting plate 15 is slidably connected to the workbench 2. A telescopic rod 18 is installed on one side of the first mounting plate 15. The telescopic rod 18 is installed on the upper side of the workbench 2. A second mounting plate 16 is installed on the upper end of the first mounting plate 15. A bottom heating template 10 is installed on the upper end of the second mounting plate 16. Fine adjustment mechanisms 17 are installed between the bottom heating template 10 and the second mounting plate 16, and between the second mounting plate 16 and the first mounting plate 15. A mold core 23 is provided on the upper end of the bottom heating template 10. A positioning mechanism 4 is installed between the bottom heating template 10 and the upper heating template 8.

[0025] The guiding mechanism 6 consists of a guide rod 11 and a guide groove 24. The guide groove 24 is located around the upper end of the pressure plate 7, and the guide rod 11 is welded to the upper end of the upper heating template 8. The guide rod 11 is slidably installed inside the guide groove 24. When the hydraulic cylinder 5 pushes the pressure plate 7 downward, the guide rod 11 is welded to the upper end of the upper heating template 8 and slidably installed inside the guide groove 24 around the upper end of the pressure plate 7. The guide groove 24 provides guidance for the guide rod 11. During the sliding process of the guide rod 11 along the guide groove 24, it can limit the horizontal displacement of the upper heating template 8 and ensure that the upper heating template 8 can only move smoothly downward in the vertical direction. This ensures that the upper heating template 8 and the bottom heating template 10 maintain a precise alignment relationship in the vertical direction, effectively preventing misalignment caused by displacement during mold closing and providing a stable working environment for rubber vulcanization.

[0026] The positioning mechanism 4 consists of a positioning rod 9 and a positioning groove 19. The positioning rod 9 is welded around the bottom of the upper heating template 8, and the positioning groove 19 is set around the top of the lower heating template 10. The bottom of the positioning rod 9 is inserted into the positioning groove 19. When the upper heating template 8 moves down and approaches the lower heating template 10, the positioning rod 9 welded around the bottom of the upper heating template 8 will gradually align with the positioning groove 19 around the top of the lower heating template 10. When the upper heating template 8 continues to move down, the bottom of the positioning rod 9 is inserted into the positioning groove 19. Through this insertion method, the relative position of the upper heating template 8 and the lower heating template 10 is further accurately determined, realizing the precise positioning of the upper and lower templates. Even if subjected to a certain external force during the vulcanization process, the cooperation between the positioning rod 9 and the positioning groove 19 can limit the relative movement of the templates, prevent misalignment, and ensure the accuracy and consistency of rubber vulcanization.

[0027] The sliding mechanism 12 consists of a slide groove 13 and a sliding foot 14. The sliding foot 14 is welded to the bottom end of the first mounting plate 15. The slide groove 13 is set on the upper side of the workbench 2. The sliding foot 14 is slidably installed inside the slide groove 13. The sliding foot 14 welded to the bottom end of the first mounting plate 15 can slide in the slide groove 13 of the workbench 2. When the bottom heating template 10 is introduced, the telescopic rod 18 pushes the first mounting plate 15. At this time, the sliding foot 14 slides in the slide groove 13, providing smooth guidance and support for the movement of the first mounting plate 15. Through this sliding connection, the bottom heating template 10 can be easily moved to the position corresponding to the upper heating template 8. At the same time, the bottom heating template 10 can be exported during use, which is convenient for material discharge.

[0028] The fine-tuning mechanism 17 consists of a movable rod 22 and a spring 21. The movable rod 22 is installed on both longitudinal sides of the bottom heating template 10 and both transverse sides of the second mounting plate 16. The movable rod 22 is slidably installed on both transverse sides of the second mounting plate 16 and both transverse sides of the first mounting plate 15. The spring 21 is installed on the outside of the movable rod 22. The movable rod 22 installed on both longitudinal sides of the bottom heating template 10 and both transverse sides of the second mounting plate 16 can slide on both transverse sides of the second mounting plate 16 and both transverse sides of the first mounting plate 15. When the positioning rods 9 around the bottom of the upper heating template 8 have a slight deviation during the alignment process, the movable rod 22 can move slightly within its installation position. The spring 21 installed on the outside of the movable rod 22 will generate elastic force to buffer and reset the movement of the movable rod 22, so that the bottom heating template 10 can automatically adjust its position within a certain range to compensate for the slight deviation. A damping sleeve 20 is slidably installed on the outer side of the movable rod 22. The damping sleeve 20 is installed on both longitudinal sides of the second mounting plate 16 or both transverse sides of the first mounting plate 15. The damping sleeve 20 slidably installed on the outer side of the movable rod 22 can increase the damping when the movable rod 22 moves, prevent the movable rod 22 from moving excessively or shaking, and make the fine adjustment of the bottom heating template 10 more stable and precise, thereby further improving the alignment accuracy of the upper and lower templates, effectively preventing misalignment, and improving the quality of rubber vulcanization.

[0029] The working principle and usage process of this utility model are as follows: In use, the workbench 2 serves as the basic supporting component, and the bracket 3 is stably installed on it. When the rubber needs to be vulcanized, the material is placed on the upper side of the bottom heating template 10. Under the action of the telescopic rod 18, the first mounting plate 15 drives the bottom heating template 10 to move. Through the sliding mechanism 12, it slides on the workbench 2 to a suitable position, so that the bottom heating template 10 and the mold core 23 on it correspond to the upper heating template 8. The hydraulic cylinder 5 is activated, and the hydraulic cylinder 5 pushes the pressure plate 7 downward, thereby driving the upper heating template 8 to move down. In the whole process, the guiding mechanism 6, the positioning mechanism 4, the sliding mechanism 12 and the fine adjustment mechanism 17 cooperate with each other to ensure that the upper and lower templates are accurately aligned and to prevent misalignment, so that the rubber can be evenly heated and compressed during the vulcanization process, ensuring the vulcanization quality.

[0030] 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.
