Abstract

The invention discloses a manufacturing method for aluminum alloy tire mold air holes. The manufacturing method comprises the following steps: drilling a hole at a corresponding position of a base mold with a drill bit and partially inlaying a steel bar in the hole; casting a rubber mold, wherein, the casted rubber mold has a small hole; inlaying a standard air pipe in the small hole in the casted rubber mold; casting a gypsum casting mold with the rubber mold in which the standard air pipe is inlaid, and leaving the standard air pipe on the gypsum casting mold; fixedly sleeving a thin walledtube on the part of the standard air pipe that extends out from the gypsum casting mold; sending the gypsum casting mold to a workshop for mold casting, wherein, after mold casting is finished, the thin walled tube stays in the obtained mold, and the part of the standard air pipe sleeved by one end of the thin walled tube extends out from the mold; striking the extending standard air pipe of the mold into the thin walled tube and removing spare parts at the back side of the mold so as to obtain an aluminum alloy tire mold with an air hole. The method provided in the invention is labor saving and time saving and enables low cost and stable quality to be achieved, suitable for being widely used.

Description

technical field [0001] The invention relates to a method for manufacturing a tire mold, in particular to a method for manufacturing air holes of an aluminum alloy tire mold which saves time and effort, has low cost and high quality. Background technique [0002] Existing tire molds belong to rubber molding molds, and the appearance and quality of tires depend on the appearance of tire molds, the fluidity of rubber materials and the quality of venting. To solve the above problems, in addition to improving the fluidity of the rubber in the compound formula, it is more important to set vent holes and vent grooves on the tire mold to facilitate the exhaust of the tire during the manufacturing process and prevent rubber shortage and gas. The occurrence of defects such as drums. Therefore tire mold must be provided with a lot of vent holes or vent grooves in the design process. [0003] For the vent holes of tire molds, the current tire mold industry generally adopts the method...
