DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-4 A mold for storing rubber edges at a tire parting position comprises an upper side plate 3, a lower side plate 4 and a pattern block 22. A parting surface 6 is formed at the junction of the upper side plate 3, the lower side plate 4 and the pattern block 22. An annular rubber storage groove 7 is provided on the parting surface 6. A first connecting block 1 and a second connecting block are respectively installed at the ends of the upper side plate 3 and the lower side plate 4 that are away from each other. A plug-in block 13 is arranged on the first connecting block 1 and the second connecting block 2. A plug-in groove 12 adapted to the plug-in block 13 is provided on the upper side plate 3 and the lower side plate 4. Two transmission sliders 19 are slidably arranged in the plug-in block 13. Limiting sockets 18 adapted to the transmission slider 19 are provided on the inner walls on both sides of the plug-in groove 12. Threaded holes 5 for fixing are provided on the upper side plate 3 and the lower side plate 4.

[0020] By providing the annular rubber storage tank 7, during the vulcanization process of the tire embryo, excess rubber can enter the annular rubber storage tank 7, and the rubber closer to the outside is less likely to be squeezed out, and the size of the annular rubber storage tank 7 is controlled to ensure the amount of rubber edge generated and the strength of the rubber edge, so that a small amount of rubber edge is generated while ensuring that the rubber edge is not torn when the tire is vulcanized and the mold is opened, and the rubber edge does not overflow along the mold parting surface 6, thereby omitting the step of manually removing rubber residue, thereby improving production efficiency and production safety, and after the vulcanization is completed and the mold is opened, the rubber edge will be completely taken out with the tire, and can be processed by subsequent trimming without affecting the appearance of the tire.

[0021] Specifically, in the present embodiment, a cavity 14 is provided in the plug-in block 13, a driving gear 11 is rotatably installed in the cavity 14, two transmission sliders 19 are slidably arranged in the cavity 14, a transmission tooth 21 meshing with the driving gear 11 is provided on the transmission slider 19, a connecting shaft 8 is installed on the driving gear 11, an adjusting knob 10 is installed on the end of the connecting shaft 8 away from the driving gear 11, a groove 9 is provided on the end of the first connecting block 1 and the second connecting block 2 away from the plug-in block 13, the adjusting knob 10 is arranged in the groove 9, two mutually symmetrical fixed blocks 20 are arranged in the cavity 14, a limiting rod 15 is arranged on the fixed block 20, a limiting hole 17 adapted to the limiting rod 15 is provided on the transmission slider 19, a return spring 16 is sleeved on the limit rod 15, one end of the return spring 16 is installed on the transmission slider 19, and the other end of the return spring 16 is installed on the fixed block 20.

[0022] By setting the plug-in block 13 and the plug-in slot 12, it is convenient to guide the upper side plate 3 and the lower side plate 4 when they are connected and fixed with the first connecting block 1 and the second connecting block 2. When fixed, the plug-in block 13 is inserted into the plug-in slot 12, and the adjusting knob 10 is driven to rotate by a tool, so that the connecting shaft 8 is driven to rotate by the adjusting knob 10, and then the driving gear 11 is rotated, and the driving gear 11 is engaged with the transmission teeth 21 on the transmission slider 19, so that the two transmission sliders 19 are driven to move away from each other, and pass through the plug-in block 13 to be inserted into the limiting plug hole 18 on the inner wall of the plug-in slot 12, so as to realize the locking between the first connecting block 1 and the second connecting block 2 and the upper side plate 3 and the lower side plate 4. The invention relates to a method for making the upper and lower side plates 3 and 4 to be tightly fixed, which simplifies the installation process of the upper side plate 3 and the lower side plate 4 and improves the work efficiency. In addition, the limit rod 15 and the limit hole 17 cooperate with each other, so that the transmission slider 19 can slide along the limit rod 15 through the limit hole 17, and the moving direction of the transmission slider 19 is guided and limited. When the transmission slider 19 slides on the limit rod 15, the reset spring 16 is squeezed or stretched, so that the elastic potential energy of the reset spring 16 can make the transmission slider 19 automatically reset, and ensure that the transmission slider 19 can always be tightly pressed against the limit plug hole 18, further ensuring the connection stability between the upper and lower side plates 3 and 4 and the first connecting block 1 and the second connecting block 2.

[0023] Specifically, in this embodiment, the size of the annular glue storage groove 7 is 6*0.6mm-8*0.8mm.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
