Technical Field

[0001] The utility model relates to the field of aviation tire molds, in particular to an aviation tire mold which is easy to position. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machinery. They are usually installed on metal rims to achieve contact with the road surface and ensure the vehicle's driving performance. Tires are generally made by mold injection.

[0003] Existing aircraft tire molds can be specifically referenced in Application No. CN202221156020.4. The mold comprises an upper mold and a lower mold, which define a tire cavity. The upper mold contains upper tread ribs, and the lower mold contains lower tread ribs. The mold also includes an upper mold ring containing a first tread rib and a lower mold ring containing a second tread rib. The upper mold, upper mold ring, lower mold, and lower mold ring together define a tire cavity. The first and second tread ribs are joined together to form a single, integrated pattern. This mold offers the advantages of high machining precision and a short processing cycle.

[0004] However, the above-mentioned tire mold is not provided with a component that can be easily positioned. When the tire is injection molded, since the tire mold cannot be positioned, the upper and lower mold positions are very likely to move during the shaping process, thereby affecting the shaping of the tire. Therefore, it is urgent to propose an easy-to-position aviation tire mold to address the above problem. Utility Model Content
