Embodiment 1

[0075] This embodiment provides a tire with a new type of sidewall pattern. This tire with a new type of sidewall pattern includes a carcass. The side of the carcass has a marking area, and a plurality of pattern units are arranged in the marking area. 101; the pattern unit 101 protrudes from the carcass, the pattern unit 101 includes a central part 102 and a plurality of extension parts 103, and the number of extension parts 103 is 3-15, preferably 7-10 , preferably 9. A plurality of extensions 103 are distributed on the side of the central part 102 along the circumferential direction, and the plurality of extensions 103 can be integrally arranged with the central part 102, or can be arranged discontinuously, with a certain gap in the middle, and the gap The value is less than or equal to 0.5mm. The central portion 102 has a height higher than that of the extension portion 103 , and the height of the central portion 102 may also be the same as that of the extension portion 1...

Embodiment 2

[0105] This embodiment provides a kind of tire mold, is used for the tire in embodiment 1, as Figure 6 or Figure 8 or Figure 10 As shown, the tire mold includes a side plate 111 on which a groove structure 112 matching the pattern unit 101 is arranged.

[0106] The side portion of the vulcanized tire can be formed with a designed raised structure through the marking area of ​​the mold. The designed raised structure constitutes the pattern area or text area of ​​the sidewall. The text area displays text, such as "ABCDEFGH" displayed in a smooth plane.

[0107] The designed raised structure can be in the pattern block area, can also surround the text area, or can be on the text area alone. It is preferable to provide the pattern region on the outer side in the tire radial direction. The groove structure 112 of the mold can be engraved using a laser.

Abstract

A tire having a sidewall pattern and a tire mold, relating to the field of tires. The tire comprises a tire body; a side of the tire body is provided with a marking area; a plurality of pattern units (101) is provided in the marking area; the pattern units (101) protrude from the tire body; the pattern units (101) each comprises a central portion (102) and a plurality of extension portions (103); the plurality of extension portions (103) is circumferentially distributed on the side of the central portion (102); the central portion (102) is higher than the extension portions (103). The tire mold is used for manufacturing the tire. The tire provides better visual and mechanical effects.

Description

technical field [0001] The invention relates to the field of tires, in particular to a tire with a novel sidewall pattern and a tire mold. Background technique [0002] There are a large number of patterns, fonts and other marks on the sidewall of the tire. These marks are made through a tire mold, and a groove structure is provided on the surface of the tire mold, and a corresponding stripe structure is obtained on the tire surface by vulcanization. [0003] Usually, the tire vulcanization mold is made of metal, and the surface of the tire mold is often processed relatively smooth, with a high degree of finish. [0004] However, the outer surface of the black tire thus obtained is smooth, and the smooth outer surface will reflect light, resulting in a poor visual effect of the appearance of the tire surface. Contents of the invention [0005] The present invention provides a tire with a new type of sidewall pattern, aiming to solve the above-mentioned problems existing ...
