Problems solved by technology

[0004] A large number of times of opening and closing the mold makes the pattern blocks mainly made of cast aluminum severely damaged in the process of collision and extrusion with steel parts (such as upper and lower side plates) or each other, thereby reducing the pattern. The service life of the block increases the production cost of the tire

Embodiment Construction

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0032] The pattern block protection structure of the embodiment of the present invention is used for the pattern block of the active tire mold, so as to reduce the wear on the surface to be protected caused by the pattern block of the active tire mold during use (such as opening and closing the mold). The pattern block protection structure of the embodiment of the present invention includes a protection block, which is installed in the groove on the surface of the pattern block to be protected, and the hardness of the material of the protection block is greater than th...

Abstract

The invention provides a pattern block protective structure, a pattern block and a tire segmental mold. The pattern block protective structure is used for the pattern block of the tire segmental mold, the pattern block protective structure comprises a protective block which is assembled in a groove of a surface to be protected of the pattern block, the hardness of the protective block material is more than that of the pattern block, and the protective block is used for reducing abrasion of the pattern block to the to-be-protected surface when the pattern block is used. The pattern block protective structure has the hardness higher than that of a pattern block matrix, can reduce the abrasion of the pattern block when the pattern block is used, can prolong the service life of the pattern block, and can reduce the using cost of the segmental mold composed of the pattern block.

Description

technical field [0001] The present invention relates to a pattern block protective structure, a pattern block and a tire active mold, in particular to a protective structure for cast aluminum or cast aluminum alloy pattern blocks, the pattern block protective structure is used for cast aluminum or cast aluminum alloy pattern blocks, the Pattern blocks are used to form tire flexible molds. Background technique [0002] At present, pattern blocks with cast aluminum as the main material are widely used in the tire mold industry, but there are generally problems of low mold life and high maintenance costs. The main reason for this problem is the pattern blocks with cast aluminum as the main material. The hardness of the matrix is ​​low (only about 50HB). During the vulcanization process of the tire, the repeated opening and closing of the mold will cause the facade (vertical surface) of the cast aluminum pattern block (such as Figure 2A The elevation of the pattern block in the...
