Description

Technical Field

[0001] The utility model belongs to the technical field of glass mold processing, and particularly relates to a multi-angle milling machine for glass molds. Background Art

[0002] Glass molds are important process equipment for forming glass products. They are key and consumable components for producing glassware. Glass molds are usually composed of two symmetrical parts. The shape of the two parts of the glass mold is similar to that of a semi-cylinder, and the area enclosed by the two halves of the glass mold is the molding cavity for forming the glassware. The manufacturing process of glass molds usually includes casting the blank (the blank is usually two half molds), processing the mating surfaces of the two half molds (also called joint surfaces), outer circle processing, inner cavity processing (also called mold cavity processing), cooling hole and insulation hole processing, positioning hole and positioning groove processing, plane air groove processing, plane milling processing, inner cavity pattern processing, mold outer surface and inner cavity lettering, mold edge milling and polishing, etc. There are many steps and a long cycle.

[0003] Glass molds are made of two mold halves. Each process requires a positioning reference for the next process to facilitate processing. Proper positioning references are crucial for ensuring glass mold processing accuracy. Improper positioning reference selection can significantly impact the accuracy of the mold's mating surfaces, which in turn can significantly impact the product's scrap rate.

[0004] Conventional milling machines are often used in the glass mold manufacturing process. To adapt to different processing steps, different milling machines or fixtures are often required, resulting in slower glass mold processing efficiency. Replacing the milling machine or fixture requires repositioning the glass mold according to the positioning reference, which takes a relatively long time and reduces processing flexibility. Any deviation will affect the processing accuracy of the glass mold. Utility Model Content
