[0017] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] See also Figure 1 to Figure 4The utility model provides a side panel mold without air holes, which includes a side panel body 9, an installation space is provided on the inner side of which to ensure the normal installation of the matching block 8 and the side panel body 9; a plurality of matching blocks 8 installed inside the installation space on the side panel body 9, the plurality of matching blocks 8 are combined with each other, and cooperate with the side panel body 9 to form a side panel mold, and an exhaust slit 1 and an exhaust main groove 3 connected to the exhaust slit 1 are provided between two adjacent matching blocks 8 to ensure that the gas generated during the vulcanization of the tire mold can directly enter the interior of the exhaust slit 1, to ensure that the internal gas is discharged and guided out of the mold, and a radial air groove 4 is provided at one end of the exhaust main groove 3 away from the exhaust slit 1, and the gas in the vulcanization process passes through the exhaust slit 1, the exhaust main slit 2, the exhaust main groove 3 and the radial air groove 4 in sequence, so that the generated gas can be smoothly discharged from the mold, and the gas is prevented from affecting the tire vulcanization process inside the mold.

[0019] Preferably, the centers of several of the mating blocks 8 of the utility model are connected to the side panel body 9 by at least one first locking bolt 5. The first locking bolt 5 ensures that the center position of the mating block 8 is fixed to reduce the movement of the mating block 8 during use. The edges of the mating block 8 are connected by at least two second locking bolts 7 to ensure that the two sides of the mating block 8 can be stably fixed on the side panel body 9 to prevent the mating block 8 from moving.

[0020] In addition, the sizes of the exhaust seam 1, the main exhaust seam 2, the main exhaust groove 3 and the radial air groove 4 of the utility model are increased successively to ensure that the gas can be discharged smoothly during exhaust. At the same time, the exhaust seam 1 is connected to the space of the vulcanized tire. The gap of the exhaust seam 1 is 0.02mm~0.03mm to prevent the material from leaking from the gap of the exhaust seam 1 when the tire is vulcanized, affecting the surface quality of the tire during vulcanization, and preventing the appearance of more fetal hair and affecting the quality of the tire.

[0021] Furthermore, the inner wall of the installation space of the utility model is in close contact with the outer wall of the matching block 8, and a positioning pin 6 is provided between the matching block 8 and the side panel body 9. The matching block 8 is positioned by the positioning pin 6 to prevent the matching block 8 from displacement, thereby facilitating the installation of the matching block 8.

[0022] In this embodiment, combined with Figure 1 to Figure 4The matching block 8 is positioned by the positioning pin 6, and then the matching block 8 is fixed to the predetermined position by the first locking bolt 5 and the second locking bolt 7. At this time, an exhaust gap 1 is formed between the two adjacent matching blocks 8. The gap of the exhaust gap 1 is 0.02mm-0.03mm, which prevents the material from entering the exhaust gap 1 during vulcanization. The gap can effectively achieve the effect of intelligent gas entry, so that the gas at this time can only enter from the inside of the vulcanization space, and then pass through the gradually expanding exhaust main seam 2, exhaust main groove 3 and radial gas groove 4 to ensure that the air generated during vulcanization inside the mold enters the exhaust gap 1 and then is discharged from the mold. When in use, firstly, several matching blocks 8 are assembled on the side plate body 9 through the positioning pins 6, and the two are fastened with the first locking bolt, the second locking bolt and the locking bolt. At this time, the gap between the matching block 8 and other matching blocks 8 is controlled by designing the size, and the exhaust gap 1 is automatically formed, so that the gap of the exhaust gap 1 is guaranteed to be 0.02mm~0.03mm. At this time, when the tire is vulcanized, the excess air passes through the exhaust gap 1 and then passes through the exhaust main gap 2 and the exhaust main groove 3 to discharge the gas into the radial air groove 4, completing the gas removal process. In this way, the excess gas can be removed and the tire rubber can be ensured not to overflow, thereby improving the tire vulcanization quality and reducing the cost.

[0023] In summary, the utility model provides a pore-free side panel mold, comprising: a side panel main body, an installation space is provided on the inner side of which to ensure the normal installation of the matching block and the side panel main body; a plurality of matching blocks installed inside the installation space on the side panel main body, the plurality of matching blocks are combined with each other, and cooperate with the side panel main body to form a side panel mold, an exhaust seam and an exhaust main groove connected to the exhaust seam are provided between two adjacent matching blocks, to ensure that when the tire mold is vulcanized, the gas generated can directly enter the interior of the exhaust seam, to ensure that the internal gas is discharged and guided out of the mold, a radial air groove is provided at one end of the exhaust main groove away from the exhaust seam, and the gas in the vulcanization process passes through the exhaust seam, the exhaust main seam, the exhaust main groove and the radial air groove in turn, so that the generated gas can be smoothly discharged from the mold, and the gas is prevented from affecting the tire vulcanization process inside the mold. In summary, the technical effect produced by the utility model is that it can improve many disadvantages of tire pore exhaust, adopt a pore-free mode, and achieve a pore-free exhaust effect through mold structure improvement, thereby improving the tire appearance and reducing the tire manufacturing cost.
