Description

Technical Field

[0001] The utility model relates to a texture structure of a tire mold for vulcanizing tires and a tire thereof. Background Art

[0002] In the field of tire manufacturing, the side part of the tire carcass is a key area that carries a large amount of important information, including marks such as patterns and fonts, which provide consumers with important information about the tire brand, model, performance, etc. These marks are made through a tire mold, and the groove structure on the mold surface is transferred to the tire surface during the vulcanization process to form corresponding texture stripes. This process is a standard practice in tire manufacturing to ensure the appearance and functionality of the tire.

[0003] However, currently, tire vulcanization molds generally use metal materials and the metal material molds are processed to a high smoothness. Such a design is beneficial to the vulcanization and molding of tires, but at the same time, it also results in a relatively smooth outer surface of the manufactured black tires. This smooth surface is prone to light reflection under specific lighting conditions, affecting the visibility of the tire identification area and reducing the overall visual texture of the tire. In some cases, this reflection effect may make the identification area of the tire appear less obvious, reducing the overall visual texture of the tire, which may be one of the reasons for consumers not to buy the tire. Although this appearance defect does not affect the performance and safety of the tire, in a market where consumers increasingly pay attention to the product appearance design, this may become an important factor affecting the purchase decision. Summary of the Invention

[0004] The purpose of the utility model is to address the above problems and provide a texture structure of a tire mold for vulcanizing tires and a tire thereof, so as to solve the limitations of the existing tire sidewall texture in terms of vision and functionality. By forming an identification area with a specific texture structure on the tire sidewall, an interference effect is generated on the tire sidewall under different lighting conditions, enhancing the shadow and contrast between light and dark, thereby significantly improving the visual attractiveness and appearance texture of the tire.

[0005] The purpose of the present utility model is achieved as follows. A texture structure of a tire mold for vulcanizing tires is provided with concave and convex textures corresponding to the identification area on the sidewall of the tire on the side plate of the tire mold. The concave and convex textures include six texture units arranged in a set manner. The texture unit is formed by cutting from the top surface of a regular triangular prism to the bottom surface of the regular triangular prism to form a quadrangular pyramid and a C-shaped conical surface convex platform. The quadrangular pyramid is a quadrangular pyramid with a rhombic base. The vertex of the quadrangular pyramid overlaps with the first corner point of the top surface of the regular triangular prism. Two outer adjacent sides of the rhombic base of the quadrangular pyramid are respectively located on two waist lines of the bottom surface of the regular triangular prism. The outer corner point of the bottom surface of the quadrangular pyramid overlaps with the first corner point of the bottom surface of the regular triangular prism, and the inner corner point of the bottom surface of the quadrangular pyramid overlaps with the center point of the bottom surface of the regular triangular prism. The C-shaped conical surface of the C-shaped conical surface convex platform is formed by scanning a C-shaped curve and two inner adjacent sides of the bottom surface of the quadrangular pyramid through a guiding line, so that a groove is formed between the C-shaped conical surface and two adjacent conical surfaces of the quadrangular pyramid. Taking the side line of the top surface of the regular triangular prism opposite to the first corner point of the top surface of the regular triangular prism as the first side line, the C-shaped curve is symmetric about the midline of the first side line and intersects the other two side lines of the top surface of the regular triangular prism. The C-shaped curve is tangent to the first side line and forms a tangent point. The guiding line is formed by the connection line from the tangent point to the center point of the bottom surface of the regular triangular prism. The six texture units are arranged in a circular array around the outer corner point of the bottom surface of the quadrangular pyramid, so that the adjacent waist lines of the bottom surface of the regular triangular prism of each texture unit are connected to form concave and convex textures.

[0006] In the present utility model, the C-shaped curve includes an arc curve and two straight lines respectively extending from the ends of the arc curve and tangent to the arc curve. The arc curve is centered at the center point of the top surface of the regular triangular prism.

[0007] In the present utility model, each concave and convex texture is connected to each other by the bottom edge of the bottom surface of the regular triangular prism to form the texture of the identification area.

[0008] In the present utility model, the connection gap between the adjacent waist lines of the bottom surface of the regular triangular prism between each texture unit is controlled within 0.05 mm.

[0009] In the present utility model, the connection gap between the adjacent bottom edges of the bottom surface of the regular triangular prism between each concave and convex texture is controlled within 0.05 mm.

[0010] In the present utility model, the length of the median line of the triangle on the bottom surface of the regular triangular prism is 0.3 - 1.2 mm; the length of the median line of the triangle on the top surface of the regular triangular prism is 0.15 - 0.9 mm; the height of the regular triangular prism is 0.25 - 0.45 mm.

[0011] In the present utility model, for a tire, the sidewall of the tire is provided with a pattern texture in the identification area, and the pattern texture is adapted to the concave and convex texture structure of the side plate of the tire mold.

[0012] The beneficial effects of the utility model are as follows: a tire with an innovative texture decorative pattern is provided through a tire mold, so that the tire sidewall has a specific concave-convex texture, and the tire sidewall logo area has a higher blackening degree and a stronger visual impact. Not only does it improve the appearance texture of the tire, but it also reduces light reflection under specific lighting, making the tire logo area more conspicuous. At the same time, the tire sidewall presents a snowflake-like groove texture, and the groove textures are connected to each other, so that the internal gap of the mold is connected as a whole, which optimizes the filling efficiency of rubber during the vulcanization process, reduces the lack of rubber, and provides rich texture details for the vulcanized tire. These innovative structures have significantly improved the tire in terms of aesthetics, functionality and production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
