The invention provides a tire mold, a pneumatic tire surface decorative rib and application thereof, the decorative rib is formed by arranging a plurality of same basic units, each basic unit is a polygonal cone, each cone comprises a bottom surface and eight surfaces, and the included angle beta between each surface and the normal direction of the bottom surface is 10-14 degrees; the included angle between the surfaces is gamma, and gamma is 20-27 degrees; the top included angle delta of the polygonal cone is 60 degrees, and the top length L of the polygonal cone is 0.05-10 mm. The pneumatic tire surface decorative rib is formed by arranging the multiple same basic units, through arrangement and combination of the basic units, pattern diversification of the decorative rib can be achieved, the maximum saturation degree can be achieved in the unit area, and finally variable high-contrast-ratio patterns/characters are formed, so that the visual impact of a product is improved, and the product quality is improved. The low gray level is ensured, the appearance is more attractive, and customer requirements are met.

    本发明提供一种轮胎模具、充气轮胎表面装饰线及其应用,装饰线由若干个相同的基础单元排列形成,所述基础单元为多边形锥体,所述锥体包括底面和8个表面,每个表面与底面法向的夹角均为β,β=10~14°;各表面之间的夹角均为γ,γ=20°~27°;所述多边形锥体的顶部夹角为δ,δ=60°,顶部长度为L,L=0.05~10mm。本发明充气轮胎表面装饰线由若干个相同的基础单元排列形成,通过对基础单元的排列组合,能够实现装饰线图案的多样化,在单位面积内达到最大饱和度,最终形成多变的高对比度图案/文字,以提升产品视觉冲击力,在确保灰度低的同时更加美观,满足客户需求。
