Problems solved by technology

[0002] At present, the commonly used glass mold manufacturing process usually includes the following processes: casting blank (the blank is usually two half molds), processing the mating surface (also called seam surface) of the two half molds of the cast blank, and machining the outer circle. , Inner cavity processing (also known as mold cavity processing), cooling hole and heat preservation hole processing, positioning groove and positioning hole processing, plane air groove processing, plane milling processing, inner cavity pattern processing, mold outer surface and inner cavity lettering, mold milling Edge and polishing, etc.; it can be seen that the processing of glass molds has many process steps, long production cycle, frequent replacement of fixtures and changes of positioning references during the processing process, and the glass mold has a special mold formed by two halves. Therefore, in the process of gl

Abstract

The invention provides a machining method of a glass mold. The machining method comprises the following steps of parison casting, parison outer circular surface turning, mold matched surface milling, side surface positioning benchmark milling, spray welding, matched surface refining, machining of other mold parts and finished product forming. In the parison outer circular surface turning step, a correction outer circular molded line corresponding to the parison outer circular surface is obtained by utilizing an image processing technology, then a positioning hole is formed by adopting the correction outer circular molded line as the benchmark, the distance between the correction outer circular molded line and the parison outer circular surface is used as the turning removal, so that the irregular problem of the outer circular molded surface can be primarily solved. By adopting the machining method, the matching precision of the glass mold matched surface can be further improved, and the qualification rate of products can be effectively increased.
