Abstract
Description
Technical Field
[0001] This utility model relates to a highly automated tire vulcanizing machine, belonging to the technical field of tire vulcanizing equipment. Background Technology
[0002] Tire vulcanization is the final step in tire manufacturing. It mainly involves processing green tires into finished tires using a vulcanizing machine. A vulcanizing machine is a piece of equipment used for vulcanizing rubber products and plays a crucial role in tire manufacturing. By applying high temperature and high pressure to the tire blank, it causes the rubber molecules to undergo a cross-linking reaction, thereby improving the tire's strength, elasticity, wear resistance, and other properties, ensuring the tire's quality and service life. With the continuous development of the automotive and tire industries, the requirements for tire uniformity and dynamic balance are becoming increasingly stringent. However, many companies are still using complex mechanical vulcanizing machines, which not only have many parts but also a low degree of automation.
[0003] During mold closing, the various stress-bearing components of the mechanical vulcanizing machine undergo elastic deformation, causing the vulcanizing position axis to deviate from the theoretical vertical position accuracy, resulting in poor mold closing accuracy. Due to the decrease in mold closing accuracy, the gap between the mold and the tire may be uneven, resulting in unclear tire tread patterns. This will affect the tire's grip and drainage performance, reduce tire safety, and affect product quality. Utility Model Content
[0004] The purpose of this utility model is to provide a highly automated tire vulcanizing machine to solve the above-mentioned problems. This objective is achieved through the following technical solution: a support platform, with a worktable and a controller respectively provided on the top and side of the support platform.

[0010] Preferably, the upper die body comprises a shell and an upper die head arranged in the shell, and the bottom surface of the upper die head is also provided with a die cavity.
[0011] The tire support is slidably arranged in the recess, when it moves to the position directly below the signal receiving device, the controller controls the electric sliding block to stop moving, and then the controller controls the upper die head in the upper die body to descend and complete the tire vulcanization work with the lower die body, after the vulcanization work is completed, the controller controls the electric sliding block to drive the tire support to move to the other end of the workbench surface, and the tire after vulcanization is completed can be taken down, then the controller controls the electric sliding block to move to the original position, i.e. the position at the beginning, the whole process has high automation degree, and due to the cooperation between the signal receiving device and the signal transmitting device, the accuracy of the upper die body and the lower die body when they are combined is also high, and the quality of the product is improved.

[0020] 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.
[0021] Please see Figures 1-3 As shown, a highly automated tire vulcanizing machine includes a support platform. A worktable and a controller are respectively located on the top and side of the support platform. A groove is provided in the center of the worktable, within which a tire support is slidably mounted. The surface of the tire support is provided with a limiting structure for positioning the tire, a lower mold body, and a signal transmitting device. The limiting structure is a protruding metal rod that can be supported at the center of the tire to be vulcanized. An upper mold body is located above the support platform and is fixedly connected to the side of the support platform via connecting rods. The connecting rods are symmetrically distributed on both sides of the upper mold body. During the movement of the tire support, the signal transmitting device and the signal receiving device are connected. A signal receiving device connected to the signal transmitting device is provided on the surface of the connecting rods. The signal transmitting device, the signal receiving device, the upper mold body, and the lower mold body are all connected to the controller.
[0022] like Figure 1 As shown, roller limiting grooves and rollers are provided on both sides of the groove. Rollers are also provided on both sides of the tire support and are slidably engaged in the roller limiting grooves. A sliding groove is provided in the groove. The bottom of the tire support is slidably connected to the sliding groove by an electric slider. The electric slider is signal connected to the controller.
[0023] like Figures 1-3 As shown, the lower mold body includes a mold cavity, a lower mold head, and a heating plate disposed on the inner surface of the mold cavity. The heating plate is an arc-shaped heating plate that is attached to the inner surface of the mold cavity. The heating plate is an arc-shaped electric heating plate that is laid inside the mold cavity, which can provide more uniform vulcanizing heat to the tire to be vulcanized. The upper mold body includes an outer shell and an upper mold head disposed inside the outer shell. The bottom surface of the upper mold head is also provided with a mold cavity.
[0024] like Figure 4As shown in the figure, the position of the tire support is V1. At this point, the end of the tire support is aligned with the end of the worktable. The position of the tire support is represented by S1. This marks the beginning of the first step of the tire vulcanization process. First, the tire to be vulcanized is placed in the mold cavity of the lower mold body. Then, the controller is operated, and the electric slider begins to move the tire support. When the tire support moves to the bottom of the upper mold body, observe... Figure 5 .
[0025] like Figure 5 As shown in the diagram, the tire support's position is V2. At this point, the tire support is directly below the upper mold body. The position of the tire support is represented by S2. At this time, the signal transmitter on the tire support sends a signal to the signal receiver. Upon receiving the signal, the controller stops the electric slider, then the upper mold head descends to close the mold. The heating plate starts working, increasing the temperature inside the mold cavity, causing the tire to undergo a vulcanization reaction under high temperature and high pressure. After vulcanization is complete, observe... Figure 6 .
[0026] like Figure 6 As shown in the figure, the position of the tire support is V3. At this time, the other end of the tire support is aligned with the other end of the workbench. The position of the tire support is represented by S3. At this time, the tire vulcanization work is completed, and the tire can be removed.
[0027] like Figure 7 As shown in the figure, the position state diagram of the tire support is V4. V4 is the same position state as V1. After the tire is removed, the controller controls the electric slider to move in the opposite direction until the tire support reaches the position S1. The entire vulcanization process is completed. Overall, the degree of automation is high, and there is no need for too much manual intervention, thereby improving the overall production efficiency.
