Technical Field

[0001] This utility model belongs to the field of tire mold technology, specifically a novel multi-piece tire mold. Background Technology

[0002] Tire molds are key pieces of equipment in tire production, used to give tires their final shape, size, and surface pattern. They transform rubber materials into finished tires that meet design requirements through a high-temperature, high-pressure vulcanization process. As a core component of tire manufacturing, their precision and quality directly affect tire performance indicators such as wear resistance, grip, and water drainage. This equipment is widely used in various tire manufacturing fields, covering passenger cars, commercial vehicles, construction machinery, agricultural machinery, aviation, and special vehicles, while also meeting the tire production needs of light transportation vehicles such as bicycles and motorcycles. With industry development, tire molds are upgrading towards higher precision, longer lifespan, and environmental friendliness, and are leveraging digital technology to achieve customized production to adapt to the market's continuously growing demand for high-performance, differentiated tires.

[0003] Existing tire molds are usually designed as a single piece, requiring complete disassembly and return to the factory or large equipment for repair, which is time-consuming and costly. When there is local wear or damage, individual parts cannot be replaced and the whole thing must be repaired or scrapped, resulting in waste of resources and low maintenance efficiency. Utility Model Content

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model provides a novel multi-piece tire mold, which effectively solves the problems of existing tire molds being usually one-piece designs, requiring overall disassembly and return to the factory or large equipment for maintenance, resulting in long cycles and high costs; and the inability to replace individual parts when there is local wear or damage, requiring overall repair or scrapping, leading to resource waste and low maintenance efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel multi-piece tire mold, comprising a base plate, a lower mounting seat fixedly installed on the top of the base plate, a lower mold installed on the top of the lower mounting seat, an upper mold provided above the lower mold, an upper mounting seat installed on the top of the upper mold, both the lower and upper molds being composed of four mold blocks, four insert blocks fixedly installed on the sides of the upper and lower molds that are far apart from each other, four slots opened on the sides of the upper and lower mounting seats that are close to each other, eight insert blocks being inserted into the corresponding slots, an opening opened in the middle of each insert block, a rotating cylinder rotatably installed inside each opening, a handwheel provided on one side of both the upper and lower mounting seats, four pushing blocks provided inside both the upper and lower mounting seats, a transmission component provided on one side of each of the two handwheels, the two transmission components being connected to the corresponding four pushing blocks respectively, and power being output to the pushing blocks through the transmission components when the handwheels rotate; an injection nozzle fixedly installed on the surface of the upper mold.

[0006] Three sliding sleeves are fixedly installed on the circumferential surface of the upper mounting base. Each sliding sleeve has a sliding rod inserted inside. The bottom of each of the three sliding rods is fixedly connected to the upper part of the base plate. Each sliding rod has a spring sleeved on its surface. The two ends of each of the three springs are fixedly connected to the sliding sleeve and the base plate, respectively.

[0007] Preferably, both transmission components include shafts, which are fixedly mounted on one side of the two handwheels. One end of each shaft extends into the interior of the upper and lower mounting seats and is fixedly mounted with a threaded rod. The surfaces of the two shafts are rotatably connected to the upper and lower mounting seats via two bushings. One end of each threaded rod is rotatably mounted with a positioning seat, and the ends of the two positioning seats that are far apart from each other are fixedly connected to the interior of the upper and lower mounting seats, respectively.

[0008] Preferably, the surface of the threaded rod is threaded with threaded sleeves, one side of each of the two threaded sleeves is fixedly mounted with a rack, one side of each of the two racks is meshed with a gear, the two gears are rotatably connected to the upper and lower mounting seats through shaft seats on the opposite sides, and crosses are fixedly mounted on the opposite sides of the two gears, with each of the four ends of the two crosses fixedly connected to eight pushing blocks.

[0009] Preferably, sliders are fixedly installed on the opposite sides of the threaded sleeves, and grooves are provided on the inner walls of the opposite sides of the upper and lower mounting seats, with the two sliders respectively installed inside the two grooves.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: During disassembly, the operator rotates the two handwheels in sequence. When the handwheels rotate, they drive the shaft to rotate inside the bushing. When the shaft rotates, it drives the threaded rod to rotate along the positioning seat. When the threaded rod rotates, it drives the threaded sleeve to move. When the threaded sleeve moves, it drives the slider to slide inside the slide groove, which increases the stability of the threaded sleeve when it moves. When the threaded sleeve moves, it drives the gear to rotate along the shaft seat through the rack.

[0011] When the gears rotate, they drive the pushing blocks to rotate via the cross. When the pushing blocks rotate, they will exit the opening of the corresponding insert block and move away from the rotating cylinder, thereby releasing the limit on the lower and upper molds. Then the upper and lower molds can be separated into four pieces and removed. This makes the tire mold adopt a multi-piece design, which is very convenient for maintenance. In case of local wear or damage, the damaged part can be replaced individually without the need for overall repair or scrapping, thereby reducing resource waste and improving maintenance efficiency.

[0020] Depend on Figures 1 to 4The present invention includes a base plate 1, a lower mounting base 2 fixedly mounted on the top of the base plate 1, a lower mold 3 mounted on the top of the lower mounting base 2, an upper mold 4 above the lower mold 3, and an upper mounting base 5 mounted on the top of the upper mold 4. Both the lower mold 3 and the upper mold 4 are composed of four mold blocks. Four insert blocks 18 are fixedly mounted on the sides of the upper mold 4 and the lower mold 3 that are far apart from each other. Four slots 19 are respectively opened on the sides of the upper mounting base 5 and the lower mounting base 2 that are close to each other. The eight insert blocks 18 are respectively inserted into the corresponding slots. Inside the slot 19, the middle of the insert block 18 is provided with an opening 20, and a rotating cylinder 21 is rotatably installed inside the opening 20. A handwheel 7 is provided on one side of the upper mounting base 5 and the lower mounting base 2. Four pushing blocks 22 are respectively provided inside the upper mounting base 5 and the lower mounting base 2. A transmission component is provided on one side of each of the two handwheels 7. The two transmission components are respectively connected to the corresponding four pushing blocks 22. When the handwheel 7 rotates, the power is output to the pushing blocks 22 through the transmission component. An injection nozzle 6 is fixedly installed on the surface of the upper mold 4.

[0021] Three sliding sleeves 8 are fixedly installed on the circumferential surface of the upper mounting base 5. Each sliding sleeve 8 has a sliding rod 9 inserted inside. The bottom of each of the three sliding rods 9 is fixedly connected to the upper part of the base plate 1. Each of the sliding rods 9 has a spring 10 sleeved on its surface. The two ends of each of the three springs 10 are fixedly connected to the sliding sleeve 8 and the base plate 1, respectively.

[0022] During disassembly, the operator rotates the two handwheels 7 in sequence. When the handwheels 7 rotate, they drive the insert 18 out of the opening 20 of the corresponding insert 18 and away from the rotating drum 21 through the transmission component, thereby releasing the restriction on the lower mold 3 and the upper mold 4. Then the upper mold 3 and the lower mold 4 can be separated into four pieces and removed. This makes the tire mold adopt a multi-piece design, which is very convenient for maintenance. In case of local wear or damage, the damaged part can be replaced individually without the need for overall repair or scrapping, thereby reducing resource waste and improving maintenance efficiency.

[0023] Both transmission components include shafts 11, which are fixedly installed on one side of the two handwheels 7. One end of each shaft 11 extends into the interior of the upper mounting base 5 and the lower mounting base 2, and each shaft 11 is fixedly installed with a threaded rod 13. The surfaces of the two shafts 11 are rotatably connected to the upper mounting base 5 and the lower mounting base 2 through two bushings 12. One end of each threaded rod 13 is rotatably installed with a positioning seat 14. The ends of the two positioning seats 14 that are far apart from each other are fixedly connected to the interior of the upper mounting base 5 and the lower mounting base 2, respectively.

[0024] The operator rotates the two handwheels 7 in sequence. When the handwheels 7 rotate, they drive the shaft 11 to rotate inside the bushing 12. When the shaft 11 rotates, it drives the threaded rod 13 to rotate along the positioning seat 14.

[0025] The surface of the threaded rod 13 is threaded with threaded sleeves 15. A rack 23 is fixedly installed on one side of each of the two threaded sleeves 15. A gear 24 is meshed on one side of each of the two racks 23. The sides of the two gears 24 that are far apart from each other are rotatably connected to the interior of the upper mounting seat 5 and the lower mounting seat 2 through the shaft seat 25, respectively. A cross 26 is fixedly installed on the sides of the two gears 24 that are close to each other. The four ends of the two cross 26 are fixedly connected to eight push blocks 22, respectively.

[0026] When the threaded rod 13 rotates, it drives the threaded sleeve 15 to move. When the threaded sleeve 15 moves, it drives the gear 24 to rotate along the shaft seat 25 through the rack 23. When the gear 24 rotates, it drives the push block 22 to rotate through the cross 26. When the push block 22 rotates, it will exit the opening 20 of the corresponding insert 18 and move away from the rotating cylinder 21, thereby releasing the restriction on the lower mold 3 and the upper mold 4.

[0027] Slider 16 is fixedly installed on the opposite sides of the threaded sleeve 15. Slide grooves 17 are opened on the inner walls of the opposite sides of the upper mounting base 5 and the lower mounting base 2. The two sliders 16 are respectively installed inside the two slide grooves 17.

[0028] When the threaded sleeve 15 moves, it drives the slider 16 to slide inside the groove 17, which increases the stability of the threaded sleeve 15 when it moves.
