Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing and processing technology, specifically to a tire mold that opens and closes quickly. Background Technology

[0002] Tires are annular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are typically mounted on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and guaranteeing vehicle performance. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and extreme temperatures during operation. Therefore, they must possess high load-bearing capacity, traction, and cushioning performance. Simultaneously, they are required to have high wear resistance and flexural strength, as well as low rolling resistance and heat generation. Tire production requires injection molding using molds.

[0003] The tire mold with rapid opening and closing, as disclosed in CN219191107U, utilizes a flow-diverting component to effectively and evenly distribute the molten plastic into the mold, improving the plasticizing effect and thus enhancing the quality of the finished product. In use, the molten plastic enters the flow-diverting pipe through the inner tube and connecting pipe. The flow-diverting bridge and the flow-diverting pipe form multiple flow-diverting holes, allowing the molten plastic to evenly enter the mold. A sealing sleeve and sealing groove enhance the sealing between the inner tube and the injection pipe, preventing leakage. The circular elastic insert and slot configuration facilitates disassembly of the flow-diverting pipe and flow-diverting bridge for cleaning or maintenance. The opening and closing component further enhances operator convenience by making mold opening and closing easier. In use, the servo motor drives the lead screw to rotate after being powered on. The rotation of the lead screw then drives the moving block to move up and down. After the moving block moves up and down, it works in conjunction with the guide block and guide rod to drive the upper mold to move up and down, so that the upper mold can quickly open and close with the lower mold. However, the existing technology still has defects:

[0004] 1. Existing technology has a support frame, workbench, etc., which is large in size, occupies a lot of space, and is not convenient for transportation, movement and placement.

[0005] 2. Due to the viscosity of the molten plastic, its flow speed is relatively slow in the connecting pipe. Furthermore, since the flow divider bridge and the annular flow divider form multiple flow dividers, the flow divider that first comes into contact with the molten plastic will release more liquid, while the flow divider that comes into contact with the molten plastic last will release less liquid. This results in an uneven amount of liquid on both sides of the mold, affecting the plasticizing effect and causing tire deformation.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] Combined with appendix Figure 1-5 The present invention is provided with a box body 1, with support plates 2 fixedly connected to the lower ends of both sides of the box body 1, a cover 3 provided on the top of the box body 1, and support plates 4 fixedly connected to the middle of both sides of the cover 3, and a bottom plate 5 provided inside the box body 1.

[0037] A lifting mechanism 6 is provided between the two sides of the housing 1 and the cover 3, including a lead screw 6.1, a positioning rod 6.2, a threaded tube 6.3, a sleeve 6.4, a positioning plate 6.5, a limiting groove 6.6, and a limiting block 6.7. The lead screw 6.1 is rotatably connected to the lower part of one side support plate 2 4, and the positioning rod 6.2 is fixedly connected to the lower part of the other side support plate 2 4. The threaded tube 6.3 is fixedly connected to the upper part of one side support plate 1 2, and the threaded tube 6.3 is threadedly connected to the lead screw 6.1. The sleeve 6.4 is fixedly connected to the upper part of the other side support plate 1 2, and the sleeve 6.4 is connected to the positioning rod 6. The two-phase system is adapted to each other. Positioning plates 6.5 are fixedly connected between the lower two sides of the cover 3 and the upper two sides of the base plate 5. Limiting grooves 6.6 are opened in the middle of the two sides inside the box 1. Limiting blocks 6.7 are set on the opposite side of the positioning plates 6.5. The limiting blocks 6.7 are adapted to the limiting grooves 6.6. The upper end of the support plate 2 4 near the lead screw 6.1 is fixedly connected to the motor 1 6.8. The motor 1 6.8 drives the lead screw 6.1 to rotate, which, together with the threaded tube 6.3, drives the cover 3 and the base plate 5 to move up and down, so that the cover 3 can be quickly opened and the tire can be taken out after the injection molding is completed.

[0038] A rotating mechanism 7 is provided in the middle of the upper part of the base plate 1, including a support rod 7.1, a worm gear 7.2, a mounting base 7.3, a worm 7.4, and a second motor 7.5. The support rod 7.1 is rotatably connected to the middle of the upper part of the base plate 5 via a bearing connection. The upper end of the support rod 7.1 is fixedly connected to a mounting plate 8, and a tire mold 9 is fixedly connected to the upper part of the mounting plate 8. The worm gear 7.2 is provided in the middle of the outer side of the support rod 7.1, and a mounting base 7.3 is provided on one side of the worm gear 7.2. The mounting base 7.3 is fixedly connected to the base plate 5. The worm 7.4 is rotatably connected to the front and rear sides of the mounting base 7.3. The worm 7.4 meshes with the worm gear 7.2. The second motor 7.5 is fixedly connected to the front end of the mounting base 7.3, and its output end is fixedly connected to the front end of the worm 7.4. The second motor 7.5 rotates the worm 7.4, which drives the worm gear 7.2 to rotate, thereby driving the support rod 7.1 and the mounting plate 8 to rotate. The mounting plate 8 then drives the tire mold 9 to rotate, achieving uniform injection molding.

[0039] An injection molding mechanism 10 is provided in the middle of the cover body 3, including a feed pipe 10.1, a diversion pipe 10.2, a discharge pipe 10.3, and a valve 10.4. The feed pipe 10.1 is inserted into the middle of the upper part of the cover body 3. The lower end of the feed pipe 10.1 extends to the lower part of the cover body 3 and is fixedly connected to the diversion pipe 10.2. The discharge pipe 10.3 is fixedly connected to both ends of the lower side of the diversion pipe 10.2. The discharge pipe 10.3 is aligned with the inside of the tire mold 9. The valve 10.4 is provided at the upper part of the feed pipe 10.1. Rubber liquid enters from the feed pipe 10.1 and falls into the inside of the tire mold 9 through the diversion pipe 10.2 and the discharge pipe 10.3 for tire injection.

[0040] In specific implementation of this utility model, such as Figure 1 As shown, valve 10.4 is opened, and rubber liquid is injected from feed pipe 10.1. The liquid falls through the diversion pipe 10.2 and discharge pipe 10.3 to both sides of the inside of the tire mold 9. At the same time, motor 7.5 is started, which, together with worm gear 7.4, worm wheel 7.2 and support rod 7.1, drives mounting plate 8 and tire mold 9 to rotate. This allows the rubber liquid to fall evenly into the inside of tire mold 9 in a circular motion, keeping the liquid surface level and ensuring the quality and effect of injection molding. After injection molding is completed, it is allowed to cool and plasticize naturally. Then, motor 6.8 is started, and the cover 3 and base plate 5 are raised synchronously through lifting mechanism 6, so that tire mold 9 is outside the box, making it easy to remove the tire.
