Problems solved by technology

[0003] After the glass is molded, the glass needs to be demolded. The prior art usually takes out the mold directly to demould the glass, but there are often the following problems: 1. When demoulding, the glass is very close to the mold, and the glass is affected by the mold. 2. After demoulding, the surface of the molded glass will have water marks and roughness due to the friction of the mold, making the glass surface not smooth and affecting the quality of the finished glass product.

Embodiment 1

[0019] A method for processing glass products, comprising the steps of:

[0020] (1) Ingredients: Mix 70 parts of quartz sand, 8 parts of limestone, 12 parts of feldspar, 6 parts of soda ash, and 1 part of boric acid as glass raw materials.

[0021] (2) Melting: Glass raw materials are melted in a continuous kiln at a melting temperature of 1300°C to form a uniform molten glass without bubbles. The melting area of ​​the continuous kiln is 140m 2 , large capacity, less heat loss, thermal efficiency is significantly higher than that of ordinary kilns, which can homogenize the temperature of the molten glass. Since the temperature of the molten glass near the bottom of the continuous kiln is low and it is in a stagnant state, the molten glass in the continuous kiln The total capacity of the liquid is greater than the amount of working glass, and the feeding amount and molding amount of continuous operation are kept in balance.

Embodiment 2

[0025] A method for processing glass products, comprising the steps of:

[0026] (1) Ingredients: Mix 75 parts of quartz sand, 9 parts of limestone, 13 parts of feldspar, 7 parts of soda ash, and 1.5 parts of boric acid as glass raw materials.

[0027] (2) Melting: Glass raw materials are melted in a continuous kiln at a melting temperature of 1400°C to form a uniform glass liquid without bubbles. The melting area of ​​the continuous kiln pool is 145m 2 , large capacity, less heat loss, thermal efficiency is significantly higher than that of ordinary kilns, which can homogenize the temperature of the molten glass. Since the temperature of the molten glass near the bottom of the continuous kiln is low and it is in a stagnant state, the total amount of molten glass in the continuous kiln is The capacity is greater than the amount of working glass, and the feeding amount and molding amount of continuous operation are in balance.

Embodiment 3

[0031] A method for processing glass products, comprising the steps of:

[0032] (1) Ingredients: Mix 80 parts of quartz sand, 10 parts of limestone, 14 parts of feldspar, 8 parts of soda ash and 2 parts of boric acid as glass raw materials.

[0033] (2) Melting: Glass raw materials are melted in a continuous kiln at a melting temperature of 1500°C to form a uniform glass liquid without bubbles. The melting area of ​​the continuous kiln pool is 150m 2 , large capacity, less heat loss, thermal efficiency is significantly higher than that of ordinary kilns, which can homogenize the temperature of the molten glass. Since the temperature of the molten glass near the bottom of the continuous kiln is low and it is in a stagnant state, the total amount of molten glass in the continuous kiln is The capacity is greater than the amount of working glass, and the feeding amount and molding amount of continuous operation are in balance.

Abstract

The invention belongs to the field of pouring molding of glass, and specifically discloses a processing method of a glass product. According to the processing method disclosed by the invention, before molten glass liquid is poured, cooling water is firstly pumped into a water-cooling through hole and wind is pumped into an air inlet, and the wind enters a second cavity and a first cavity; then the molten glass liquid is injected into a forming cavity, a draught fan is closed and ventilation is stopped when demolding is carried out; meanwhile, pumping of the cooling water is stopped, an air pump is started, the air in the first cavity and the second cavity is pumped out by the air pump, a fourth graphene plate and an upper mold are taken out, so that successful demolding can be carried out. According to the scheme, a method, which is easy in demolding and is capable of making the surface of formed glass smooth after demolding, of the glass product is provided.

Description

technical field [0001] The invention relates to the field of glass pouring molding. Background technique [0002] In the production process of glass products, glass needs to be shaped, and glass forming molds are used in the glass forming step. Glass forming molds are usually metal molds, which are used to press glass products to form them. The working temperature of the metal mold surface is generally 600-900°C, while the temperature of the molten glass is 1300-1600°C. Under such temperature conditions, the molten glass is easy to adhere to the surface of the metal mold. [0003] After the glass is molded, the glass needs to be demolded. The prior art usually takes out the mold directly to demould the glass, but there are often the following problems: 1. When demoulding, the glass is very close to the mold, and the glass is affected by the mold. 2. After demoulding, the surface of the molded glass will have water marks and roughness due to the friction of the mold, which w...
