Description

Technical Field

[0001] The utility model relates to a tire mold for vulcanized tires and a tire thereof. Background Art

[0002] In the field of tire manufacturing, the side of the tire carcass is a key area that carries a lot of important information, including patterns, fonts and other markings, which provide consumers with important information about the tire brand, model, performance, etc. These markings are made through the 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 are generally made of metal, and the metal molds are processed to a higher degree of finish. Although such a design is conducive to the vulcanization molding of the tire, it also results in a relatively smooth outer surface of the manufactured black tire. This smooth surface is prone to light reflection under certain lighting conditions, affecting the visibility of the tire logo area and reducing the overall visual texture of the tire. In some cases, this reflection effect may make the tire logo area appear less obvious, reducing the overall visual texture of the tire, which may be one of the reasons why consumers are reluctant to buy the tire. Although this appearance defect does not affect the performance and safety of the tire, it may become an important factor affecting purchasing decisions in a market where consumers are increasingly paying attention to product appearance design. Summary of the invention

[0004] The purpose of the utility model is to provide a tire mold for vulcanized tires and tires thereof in order to solve the deficiencies of the existing tire sidewall texture structure in visual effects and functionality, so that the marking area with the texture structure on the tire sidewall can produce an interference effect under different lighting conditions, enhance the shadow and light-dark contrast and visibility, and improve the visual impact and appearance texture of the tire.

[0005] The purpose of the utility model is achieved in this way. A tire mold for vulcanized tires, the side plate of the tire mold is provided with a texture corresponding to the tire sidewall identification area, the texture includes a plurality of texture units arranged in a set manner; the bottom of the texture unit has three equal-length ~-shaped side lines, the three side lines are connected end to end around the central annular array of the spiral center and the mold is pulled away from the mold side plate to form a frustum-shaped protrusion, the protrusion forms three bottom points, three curved bevel stripes and a top surface, the curved bevel stripes are ~-shaped, and the top surface is parallel to the side plate of the mold; each texture unit overlaps with the adjacent three texture units through the bottom point overlap and the side lines are connected to each other, so that the two opposite curved bevel stripes are connected to form a ~-shaped leaf-shaped groove.

[0006] The utility model has a side line composed of two arcs of equal length and diameter, and the radius of each arc is 0.1875-0.75mm.

[0007] In the utility model, every two curved inclined stripes of the protrusion intersect into a curve from the corner point of the top surface to the bottom point, and the height of the protrusion corner gradually changes from the corner point to the bottom point to form a sharp angle, and the height gradually changes to 0 at the bottom point.

[0008] In the utility model, the distance from the corner point to the bottom point of the curve is 0.25-0.75 mm.

[0009] In the utility model, the overlap of the bottom points of each texture unit and the adjacent three texture units and / or the gap of the edge line connection are controlled within 0.05mm.

[0010] In the utility model, the three raised curved inclined stripes have the same draft angle, which is 12-40 degrees.

[0011] In the utility model, the height between the top surface of the protrusion and the surface of the side plate of the mold is 0.25-0.35mm.

[0012] In the utility model, the curved bevel stripes are parallel to the side plates, and the distance between two bottom points of each curved bevel stripe is 0.6-2.5mm.

[0013] The utility model relates to a tire. The side wall of the tire is provided with a pattern texture of a marking area. The pattern texture is matched with the side plate texture of a tire mold.

[0014] 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 specific raised stripes, 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 mold has a ~-shaped blade-shaped groove texture that is 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 and reduces the lack of rubber. These innovative structures have significantly improved the aesthetics, functionality and production efficiency of the tire. BRIEF DESCRIPTION OF THE DRAWINGS
