Problems solved by technology

[0003] At present, the processing of glass molds has the characteristics of many process steps, long production cycle, frequent replacement of fixtures and changing positioning references during the processing process, and the glass mold has the particularity of being formed by two halves of the mold; therefore, the glass mold In the process of high-quality processing, the selection of positioning datum is particularly important, because the careless selection of positioning datum will greatly affect the matching accuracy of the mating surface of the glass mold, and the level of fitting accuracy will greatly affect the scrap rate of the product

Abstract

The invention discloses a high-quality processing technology of a glass mold. The high-quality processing technology comprises the following steps: a, parison casting; b, rough machining; c, heating;d, spray welding; e, tempering; f, finish machining; and g, polishing. Through the manner, in the high-quality processing technology of the glass mold, a half surface is taken as a positioning reference without change, so that the production technology is greatly simplified, and the effect of saving labor, time and effort is achieved; and the processing precision is high, so that efficient, high-speed and high-quality production of a mouth mold of the glass mold is realized, the service life of the glass mold is prolonged, and good economic benefits are brought.

Description

technical field [0001] The invention relates to the technical field of glass molds, in particular to a high-quality processing technology of glass molds. Background technique [0002] Glass is one of the materials that people often come into contact with in daily life. Glass has good corrosion resistance and acid resistance. Glass bottles made of glass are very suitable for holding acidic liquids such as vegetable juice drinks. At the same time, glass bottles also have Good barrier performance can prevent the invasion of oxygen and other gases to the contents, and prevent the volatile components of the contents from volatilizing into the atmosphere. Glass bottles can also be recycled repeatedly. In the current situation of scarce resources, The use of glass containers is the general trend, and glass bottles need to be shaped with special glass molds during the production process. [0003] At present, the processing of glass molds has the characteristics of many process step...
