Problems solved by technology

Once the outer circle of the side panel is sunken, it is often difficult to repair, and the side panel will be damaged, resulting in waste of cost investment
[0005] At the same time, the depression of the side plate will damage the pattern block and affect the matching accuracy of the mold. The vulcanized tire will have rubber edges, which seriously reduces the service life of the mold and also affects the appearance quality of the tire.

[0038] The first embodiment: as figure 2 As shown, the outer circle 3 of the side plate is used as the outer arc of the movable block 4, and the two corners of the outer arc of the movable block 4 are processed with positioning platforms 9.

[0039] The positioning platform 9 includes two circular arcs and two straight lines perpendicular to the outer arc of the movable block 4 .

[0040] Such as image 3 As shown, the two arcs are tangent to each other and are respectively tangent to the two straight sides to ensure a smooth transition and facilitate installation.

[0041] The straight line edge needs to be perpendicular to the outer arc of the movable block 4, which is convenient for processing.

[0042] The positioning table 9 can prevent the movable block 4 from moving in the circumferential direction and the radial direction on the side plate 2, and the positioning is accurate, so that the side plate 2 and the movable block 4 will not be dislocated.

Abstract

The invention discloses a tire mold side plate and a tire mold. A positioning stop piece is arranged at the position where the side plate is in contact with the outer edge of a loose block, circumferential and radial movement of the loose block on the side plate is limited by the positioning stop piece, and positioning is achieved. According to the tire mold side plate and the tire mold, deformation of the excircle of the side plate in the using process of the mold is avoided, the mold service life is prolonged, the tire precision can be effectively ensured, the tire service life is prolonged,and the safety is improved.

Description

technical field [0001] The invention relates to a tire mold side plate and a tire mold. Background technique [0002] With the growing automobile industry and the rapid development of highways, the performance requirements for tires are also getting higher and higher. Considering the requirements of tire running stability, safety, grip and other aspects, there are more and more tires with low aspect ratio, and the sidewall height of tires with low aspect ratio will be small. The font and pattern on the sidewall of the tire are realized by processing the font on the side plate where the tire mold contacts the tire. Fonts on the side panels, such as trademarks, patterns, speed grades, skeleton materials or / and certifications, are often made into flexible blocks and embedded on the side panels. The movable block is usually connected to the side plate from the back of the side plate by connecting screws. [0003] The shape and structure of these active blocks have a significa...
