Embodiment Construction

[0006] The invention relates to a manufacturing method of an automobile tire mold. The manufacturing method is as follows: the tire mold cavity is processed by a mold steel car, and then the tire mold cavity is installed in a special EDM tire molding machine when making the pattern part of the tire mold. On the machine, according to the principle of electric discharge machining, the finished alloy copper electrodes are used to form the pattern part of the tire mold cavity by electric discharge machining. Processing, in order to eliminate the phenomenon of sheet carbonization during processing.

Abstract

The invention relates to an auto-tyre mould making method, firstly completing the die space by mould steels, then installing the die space on the inequal-divided electro-spark tyre molder to make the figures part and then making electro-spark molding on the figured part by the finished alloy copper electrodes. It has largely improved and heightened strength, rigidity, corrosion resistance and wearability as well as figure surface fineness and size precision, and prolongs the using life.

Description

1. Technical field [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...
