Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine technology, specifically a vulcanizing machine for rubber tires. Background Technology

[0002] The rubber tire vulcanizing machine is an indispensable core piece of specialized equipment in the tire production process. By precisely controlling three key parameters—temperature, pressure, and time—it causes the soft, viscous raw rubber blank to undergo a vulcanization reaction under high temperature and high pressure, transforming it into a finished tire with specific shape, strength, elasticity, and durability.

[0003] For example, an existing Chinese patent (CN212498524U) discloses a rubber tire vulcanizing machine, including a gantry frame. A horizontal plate is fixed between the two sides of the gantry frame, and a hydraulic cylinder is fixed on the horizontal plate. The upper end of the hydraulic rod of the hydraulic cylinder passes through the horizontal plate and slides with it. A movable plate is fixed to the upper end of the hydraulic rod of the hydraulic cylinder. A lower mold is provided on the movable plate, and a lower mold core is provided inside the lower mold. An arc-shaped groove for placing a tire is opened on the top of the lower mold core. A fixed plate is fixed to the bottom of the gantry frame, and an upper mold corresponding to the position of the lower mold is fixed on the bottom surface of the fixed plate. A lifting component for ejecting the lower mold core from the lower mold is installed on the movable plate. In this utility model, the lower mold core is set inside the lower mold, and a lifting component is installed on the movable plate. This facilitates the worker to eject the lower mold core from the lower mold using the lifting component, thereby facilitating the worker to disassemble the lower mold core and remove the tire fitted on the lower mold core.

[0004] Currently, some traditional vulcanizing machines still rely on manual labor to pick up tires. Since the temperature of the vulcanized tires is high, manual picking up not only has low production efficiency, but also easily causes burns to operators, resulting in poor operational safety and failing to meet the requirements of efficient and safe production. Utility Model Content

[0005] The purpose of this invention is to provide a vulcanizing machine for rubber tires to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vulcanizing machine for rubber tires, comprising: a base plate and a top plate, guide posts fixed at the four corners of the top of the base plate, a top plate fixed at the top of the guide posts, a hydraulic cylinder fixed at the center of the top of the top of the top plate, an upper vulcanizing mold fixed at the bottom end of the piston rod of the hydraulic cylinder, a lower vulcanizing mold fixed at the center of the top of the base plate, a guide rail fixed on one side of the top of the base plate, a sliding bracket slidably provided on the top of the guide rail, a support rod slidably provided on one side of the sliding bracket, a moving plate fixed at the bottom of the support rod, double-headed cylinders fixed on both sides of the bottom of the moving plate, and top blocks fixed at both ends of the double-headed cylinders.

[0007] Furthermore, a lifting plate is fixed to the bottom end of the hydraulic cylinder piston rod, and the vulcanizing upper mold is fixed to the center of the bottom of the lifting plate.

[0008] Furthermore, the lifting plate has guide holes at its four corners that cooperate with the guide posts.

[0009] Furthermore, the sliding bracket is L-shaped, and a guide groove that mates with the guide rail is provided at the bottom of the sliding bracket. A servo motor is fixed to one side of the bottom of the sliding bracket, and a gear is fixed to one end of the output shaft of the servo motor. A rack is fixed to one side of the top of the base plate, and the gear meshes with the teeth on the rack.

[0010] Furthermore, a lead screw is rotatably connected to one side of the sliding bracket, and a lead screw nut is provided on the outside of the lead screw. One end of the support rod is fixed to one side of the outer wall of the lead screw nut.

[0011] Furthermore, one side of the sliding bracket is fixed with bearing seats at both ends of the lead screw, and the lead screw is rotatably connected between the bearing seats through bearings.

[0012] Furthermore, a lead screw drive motor is fixed to the outer wall of the bearing seat at the bottom, and one end of the output shaft of the lead screw drive motor is fixed to the bottom end of the lead screw.

[0013] Furthermore, the sliding bracket has a lifting guide groove inside for raising and lowering the support rod.

[0014] Furthermore, the length of the rack is greater than twice the diameter of the vulcanizing lower die.

[0015] Furthermore, there are two guide rails, which are arranged in parallel.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention utilizes a sliding bracket that moves along a guide rail and a support rod that rises and falls to precisely move a top block to both sides of the high-temperature tire inside the vulcanizing mold. A double-headed cylinder then drives the top block to open and close, clamping the tire. Through the linkage of the sliding bracket and the support rod, the tire is removed from the vulcanizing mold and transported to a designated location. This solves the safety hazard of burns from manual material handling, while also significantly improving material handling efficiency and meeting the demands of high-efficiency production.

[0018] Through precise control of servo motors and lead screw drive motors, the material handling mechanism achieves rapid horizontal movement and vertical lifting. The top block can accurately and quickly clamp and transport tires, with a material handling speed far exceeding that of manual labor. It can also operate continuously and stably without rest, greatly improving material handling efficiency. At the same time, in conjunction with the automated mold closing and opening mechanism composed of hydraulic cylinders and lifting plates, the entire process of vulcanization and material handling is automated, further improving overall production efficiency and meeting the needs of large-scale, high-efficiency production.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figures 1-7This utility model provides a technical solution: a vulcanizing machine for rubber tires, comprising: a base plate 1 and a top plate 3, guide pillars 2 fixed at the four corners of the top of the base plate 1, the top plate 3 fixed at the top of the guide pillars 2, a hydraulic cylinder 4 fixed at the center of the top of the top of the top plate 3, an upper vulcanizing mold 19 fixed at the bottom of the piston rod of the hydraulic cylinder 4, a lower vulcanizing mold 6 fixed at the center of the top of the base plate 1, and the hydraulic cylinder 4 driving the upper vulcanizing mold 19 to rise and fall, thereby realizing automated operation of mold closing and opening.

[0030] A guide rail 7 is fixed to one side of the top of the base plate 1. A sliding bracket 8 is slidably mounted on the top of the guide rail 7. A support rod 12 is slidably mounted on one side of the sliding bracket 8. A movable plate 13 is fixed to the bottom of the support rod 12. Double-headed cylinders 14 are fixed to both sides of the bottom of the movable plate 13. Top blocks 15 are fixed to both ends of the double-headed cylinders 14. By moving the sliding bracket 8 along the guide rail 7 and raising and lowering the support rod 12, the top blocks 15 are precisely moved to both sides of the high-temperature tire inside the vulcanizing mold 6. Then, the double-headed cylinders 14 drive the top blocks 15 to open and close, clamping the tire. Through the linkage of the sliding bracket 8 and the support rod 12, the tire is removed from the vulcanizing mold 6 and transported to a designated position. This solves the safety hazard of burns caused by manual material handling. At the same time, the speed of automated material handling is much higher than that of manual handling, greatly improving material handling efficiency and meeting the needs of high-efficiency production.

[0031] A lifting plate 5 is fixed to the bottom end of the piston rod of the hydraulic cylinder 4, and the vulcanizing upper mold 19 is fixed to the center of the bottom of the lifting plate 5. The lifting plate 5 serves as an intermediate connecting component, with one end fixed to the bottom end of the piston rod of the hydraulic cylinder 4 and the other end fixed to the vulcanizing upper mold 19. When the piston rod of the hydraulic cylinder 4 extends or retracts, it will drive the lifting plate 5 to move up and down synchronously, thereby driving the vulcanizing upper mold 19 to move up and down together with the lifting plate 5, realizing the mold closing and opening actions.

[0032] The lifting plate 5 has guide holes at its four corners that mate with the guide posts 2. The guide holes at the four corners of the lifting plate 5 precisely match the guide posts 2 at the four corners of the top of the base plate 1. When the lifting plate 5 moves up and down under the drive of the hydraulic cylinder 4, the guide posts 2 pass through the guide holes to precisely guide and limit the lifting movement of the lifting plate 5, restricting the lifting plate 5 to move only in the vertical direction of the guide posts 2, and preventing horizontal offset, tilting or shaking.

[0033] The sliding bracket 8 is L-shaped, with a guide groove at its bottom that mates with the guide rail 7. A servo motor 16 is fixed to one side of the bottom of the sliding bracket 8, and a gear 17 is fixed to one end of the output shaft of the servo motor 16. A rack 18 is fixed to one side of the top of the base plate 1, and the gear 17 meshes with the teeth on the rack 18. The L-shaped design of the sliding bracket 8 facilitates the installation of material-related components such as the support rod 12 and the lead screw 9, and also ensures the compact structure of the material-picking mechanism, saving space. The guide groove at the bottom of the sliding bracket 8 precisely matches the guide rail 7, providing guidance for the horizontal movement of the sliding bracket 8 and ensuring that the sliding bracket 8 can only move along the length of the guide rail 7. The servo motor 16 serves as the power source for the horizontal movement of the sliding bracket 8. During operation, the output shaft drives the gear 17 to rotate. Since the gear 17 meshes with the rack 18 on the base plate 1, the rotation of the gear 17 moves along the length of the rack 18, thereby driving the sliding bracket 8 to move horizontally along the guide rail 7 along with the gear 17, thus achieving the horizontal position adjustment of the material-picking mechanism.

[0034] A lead screw 9 is rotatably connected to one side of the sliding bracket 8. A lead screw nut 11 is provided on the outer side of the lead screw 9. One end of the support rod 12 is fixed to one side of the outer wall of the lead screw nut 11. The lead screw 9 is rotatably connected to one side of the sliding bracket 8. The lead screw nut 11 is threadedly engaged with the lead screw 9 to form a lead screw transmission mechanism. One end of the support rod 12 is fixed to the lead screw nut 11. When the lead screw 9 rotates, the lead screw nut 11 will move up and down along the length of the lead screw 9. That is, the rotation of the lead screw drives the nut to move linearly, which in turn drives the support rod 12 to move up and down with the lead screw nut 11, realizing the vertical lifting and lowering of the moving plate 13, the double-headed cylinder 14, and the top block 15.

[0035] A bearing housing is fixed to both ends of the lead screw 9 on one side of the sliding bracket 8. The lead screw 9 is rotatably connected between the bearing housings via bearings. The bearings are installed inside the bearing housings, and both ends of the lead screw 9 pass through the inner rings of the bearings and are fixed to the bearings. This allows the lead screw 9 to rotate flexibly and smoothly under the support of the bearing housings and through the rotational action of the bearings, reducing the frictional resistance during the rotation of the lead screw 9. At the same time, it provides precise positioning for the lead screw 9 and limits its axial and radial displacement.

[0036] A lead screw drive motor 10 is fixed to the outer wall of the bearing housing at the bottom. One end of the output shaft of the lead screw drive motor 10 is fixed to the bottom end of the lead screw 9. The lead screw drive motor 10 serves as the power source for the rotation of the lead screw 9. It is fixed to the outer wall of the bearing housing at the bottom, and its output shaft is fixedly connected to the bottom end of the lead screw 9. When the lead screw drive motor 10 is working, the output shaft will drive the lead screw 9 to rotate synchronously. In turn, through the cooperation between the lead screw 9 and the lead screw nut 11, the support rod 12 will move up and down.

[0037] The sliding bracket 8 has a lifting guide groove inside for the lifting of the support rod 12. The support rod 12 passes through the lifting guide groove and is fixed with the screw nut 11. When the support rod 12 moves up and down under the drive of the screw nut 11, the lifting guide groove will guide and limit the support rod 12, restricting the support rod 12 to move only in the vertical direction of the lifting guide groove, and preventing horizontal offset, swaying or twisting.

[0038] The length of rack 18 is greater than twice the diameter of vulcanizing lower mold 6. This ensures that when gear 17 moves along rack 18, it can drive sliding bracket 8 to move a sufficient distance along guide rail 7, so that sliding bracket 8 can drive the material picking mechanism completely away from above vulcanizing lower mold 6, and can also drive the material picking mechanism to move precisely to directly above vulcanizing lower mold 6.

[0039] There are two guide rails 7, which are arranged in parallel. The two guide rails 7 are fixed parallel to each other on one side of the top of the base plate 1. The guide groove at the bottom of the sliding bracket 8 cooperates with the two guide rails 7 respectively. The two parallel guide rails 7 together provide guidance and support for the horizontal movement of the sliding bracket 8, ensuring that the sliding bracket 8 remains stable and does not tilt or deviate when it moves horizontally along the guide rails 7.

[0040] This invention utilizes a sliding bracket 8 that moves along a guide rail 7 and a support rod 12 that rises and falls to precisely move a top block 15 to both sides of the high-temperature tire inside the vulcanizing lower mold 6. Then, a double-headed cylinder 14 drives the top block 15 to open and close, clamping the tire. Through the linkage of the sliding bracket 8 and the support rod 12, the tire is removed from the vulcanizing lower mold 6 and transported to a designated location. This solves the safety hazard of burns from manual material handling, while the automated material handling speed is far higher than manual handling, significantly improving material handling efficiency and meeting the needs of high-efficiency production.

[0041] Through the precise control of the servo motor 16 and the lead screw drive motor 10, the material handling mechanism can move quickly horizontally and lift vertically. The top block 15 can accurately and quickly clamp and transport the tires. The material handling speed is much higher than that of manual labor, and it can operate continuously and stably without rest, which greatly improves the material handling efficiency. At the same time, in conjunction with the automated mold closing and opening mechanism composed of the hydraulic cylinder 4 and the lifting plate 5, the vulcanization and material handling processes are fully automated, which further improves the overall production efficiency and meets the needs of large-scale and high-efficiency production.

[0042] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
