Detailed Implementation

[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 scope of protection of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A tire mold side plate flip-up telescopic support includes a top frame 1. The lower end of the top frame 1 is fixedly connected to two symmetrically distributed hinged frames 2. The hinged frames 2 are hinged to the inside of the hinged frames 3. The upper inner side of the frame 3 is fixedly connected to a storage rack 4. The storage rack 4 is provided with a mold bolt fixing device 5. The middle inner side of the frame 3 is fixedly connected to a pull frame 6. The center of the top frame 1 is fixedly connected to a guide tube 7. The guide tube 7 is slidably connected to a drive frame 8. The lower end of the frame 3 is fixedly connected to a connecting ring 10. The connecting ring 10 is laterally slidably connected to a mold bolt 11. The end of the connecting ring 10 away from the frame 3 is fixedly connected to a fixing cover 13. The fixing cover 13 is slidably connected to a pull ring rod 14. The upper end of the pull ring rod 14 is fixedly connected to a limit seat 15. A spring 16 is provided on the outer side of the pull ring rod 14.

[0022] See Figure 1 , Figure 3 A lifting ring 9 is fixedly connected to the upper end of the drive frame 8. The lifting ring 9 is slidably connected to the upper end of the guide tube 7. The pull frame 6 is hinged to the drive frame 8. The lifting ring 9 can be connected to the hook. An annular groove 12 is provided on the outer side of the mold bolt 11. The limiting seat 15 is slidably connected to the annular groove 12. The annular groove 12 allows the mold bolt 11 to rotate freely. The fixed cover 13 is in rotatable contact with the mold bolt 11. The limiting seat 15 is slidably connected to the fixed cover 13. The limiting seat 15 can limit the mold bolt 11. One end of the spring 16 is fixedly connected to the fixed cover 13. The other end of the spring 16 is fixedly connected to the limiting seat 15. The spring 16 can automatically reset the limiting seat 15 through elastic force.

[0023] See Figure 1 , Figure 2 , Figure 4The mold bolt fixing device 5 includes a connecting rod 51, an internal sliding connecting rod 51 of the storage rack 4, a handle 52 fixedly connected to the outside of the connecting rod 51, the handle 52 contacting the storage rack 4, a support frame 54 fixedly connected to the end of the connecting rod 51 away from the handle 52, a rubber sheet 55 fixedly connected to the outer arc surface of the support frame 54, and a second spring 53 provided on the outside of the connecting rod 51. The rubber sheet 55 can increase the friction between the bolt inserted into the storage rack 4 and the support frame 54. One end of the second spring 53 is fixedly connected to the storage rack 4, and the other end of the second spring 53 is fixedly connected to the support frame 54. The second spring 53 can support the support frame 54 through its elasticity.

[0024] The specific implementation process of this utility model is as follows: When in use, pull the handle 52. The handle 52 drives the support frame 54 to move through the connecting rod 51 and compresses the second spring 53. Then, the unused mold bolt 11 is inserted into the corresponding hole of the storage rack 4. Then, release the handle 52. The second spring 53 returns to its original position. The second spring 53 can use its elasticity to drive the support frame 54 to press against the outside of the mold bolt 11, thus completing the limiting of the mold bolt 11. This makes it easier to carry and take out various types of mold bolts 11.

[0025] When it is necessary to flip the tire mold, take the corresponding mold bolt 11, and then pull the pull ring rod 14 downward. The pull ring rod 14 drives the limit seat 15 to move downward and compresses the spring 16. When the limit seat 15 slides into the inside of the fixing cover 13, the corresponding mold bolt 11 is then inserted into the inside of the connecting ring 10. After insertion, release the pull ring rod 14, and the spring 16 returns to its original position. The spring 16 can use its elasticity to drive the limit seat 15 to slide into the annular groove 12 of the mold bolt 11, thus completing the installation of the mold bolt 11. After installation, the mold bolt 11 can be installed inside the tire mold. After installation, it can be hoisted and flipped.

[0026] This utility model adds a connecting ring, a limiting seat, and a pull ring rod to the frame rod. During use, the limiting seat can be driven by the elastic force of the spring to slide into the annular groove of the mold bolt to limit the mold bolt. When replacement is required, the limiting seat can be removed from the annular groove to release the limiting of the mold bolt, thus making the mold bolt easier to replace and improving the efficiency of use.

[0027] This utility model adds a storage rack, support frame, and rubber sheet to the frame rod. During use, unused mold bolts can be inserted into the storage rack. At the same time, the elastic force of spring two can drive the rubber sheet on the outside of the support frame to press against the outside of the mold bolt, thus completing the carrying of the mold bolt. This makes it easier to take out various mold bolts.
