Soda-lime glass product and manufacturing method thereof

Abstract

The invention discloses a soda-lime glass product and a manufacturing method thereof. The soda-lime glass product comprises a spherical sleeve and a modeling piece, wherein the interior of the spherical sleeve is of a hollow structure; the modeling piece is integrally arranged in the spherical sleeve; a base is arranged at the bottom of the spherical sleeve; and a round hole is formed in the upperend of the spherical sleeve. According to the invention, the metal molding die is fast in cooling; Through forming by furnace base, an internal molding part is firstly molded and processed; then, theglass is subjected to melting-down heating treatment; through temperature difference between the inner glass and the outer glass, the external glass is melted while the internal modeling piece is notmelted; the glass blank is placed in the shape mold to be subjected to blowing cooling forming, so that the soda-lime glass product with an integrated structure is machined, the thickness of the soda-lime glass product ranges from 3 mm to 50 mm, the soda-lime glass product is firm in structure, not prone to damage and good in crystal texture, and secondary and tertiary cold machining of traditional sintering is broken through.

Description

technical field [0001] The invention belongs to the technical field of glass processing, and in particular relates to a soda-lime glass product and a manufacturing method thereof. Background technique [0002] At present, during the processing operation of glass products, since the glass material is cooled from the outside to the inside, after external cooling, the glass products will be shaped and cannot be blown. Therefore, in the processing of glass products with a nested structure, a split-type combination method is usually adopted, that is, each part is processed separately, and then the parts are combined by heating and melting. This processing method is prone to occur during the melting process. If the joints are not tight, cracks are prone to appear at the joints, resulting in an unstable overall structure. Contents of the invention [0003] The object of the present invention is to provide a soda-lime glass product and a manufacturing method thereof, so as to sol...

Problems solved by technology

[0002] At present, during the processing operation of glass products, since the glass material is cooled from the outside to the inside, and after external cooling, the glass products will be shaped and cannot be blown.

Therefore, in the processing of glass products with a nested structure, a split-type combination method is usually adopted, that is, each part is processed separately, and then the parts are combined by heating and melting. This processing method is prone to occur during the melting process. If the joints are not tight, cracks are likely to appear at the joints, resulting in an unstable overall structure
