Technical Field

The invention relates to the technical field of glass molds, in particular to an oxidation heat treatment process of a glass mold.

Background

Glass is one of materials frequently contacted in daily life of people, the glass has good corrosion resistance and acid corrosion resistance, a glass bottle made of the glass is very suitable for containing acidic liquid such as vegetable juice, beverages and the like, meanwhile, the glass bottle also has good barrier property, invasion and attack of gases such as oxygen and the like to contents can be well prevented, volatile components of the contents can be prevented from volatilizing into the atmosphere, the glass bottle can be recycled repeatedly, under the condition that the current resources are deficient, the glass container is used, and the glass bottle needs to be shaped by using a special glass mold in the production process.

At present, most glass molds have the characteristics of complex molded surface, high strength, high machining precision requirement and the like, but the glass molds produced in the prior art have the defects of easy cracking and the like, and the service life is greatly influenced. The reason for influencing the current mold production process is that the heat treatment technology is unstable and immature, so that the glass mold is high in production cost and rework rate, and development of the glass mold production industry is restricted.

Disclosure of Invention

In order to solve the technical problems, the invention adopts a technical scheme that: the oxidation heat treatment process of the glass mold comprises the following specific steps:

a. cleaning: cleaning the surface of the glass mold, and removing oil stains;

b. preheating: preheating the cleaned glass mold in a heating furnace with the furnace temperature of 280-380 ℃ for 35-45 minutes;

c. quenching and heating: when the glass mold is cooled to the temperature of 180-;

d. annealing and heating: heating to 435-.

In a preferred embodiment of the invention, the glass mold comprises at least 88-92% nickel.

In a preferred embodiment of the present invention, a nickel oxide layer is formed on the surface of the glass mold after the glass mold is subjected to the oxidation heat treatment.
