[0001] The invention relates to a method for manufacturing a tire mold, in particular to a method for manufacturing an automobile tire mold. 2. Background technology
[0002] The currently used and manufactured automobile tire molds are also called two-half molds for precision casting, and the pattern circles of the tire molds are directly fastened on the mold body by integrally cast aluminum patterns. Due to the limited characteristics of cast aluminum materials, there are defects in cast aluminum alloys such as shrinkage cavities, shrinkage porosity, and casting pinholes. The accuracy is poor, so the service life of the mold is short. 3. Contents of the invention
[0003] The object of the present invention is to provide a kind of overcoming the weak point of above-mentioned prior art, the automobile tire mold manufacturing method that mold service life is longer.
[0004] In order to achieve the above object, the technical solution of the present in...
