Mould for manufacturing glass container

Abstract

The invention discloses a mould for manufacturing a glass container and belongs to the technical field of glass moulds. The mould for manufacturing the glass container comprises a pair of bottle semi-moulds which have the same shape and are opposite to each other; and each of the bottle semi-moulds has a bottle-neck cavity and a bottle body cavity. The mould is characterized in that: a heat insulation groove is reserved on the bottle semi-mould around the mouth of the bottle-neck cavity, and the upper part of the heat insulation groove is sealed by a heat insulation groove cover. As the heat insulation groove is formed at the mouth of the bottle-neck cavity of the bottle semi-moulds, the heat dissipation speed of the bottle mouth is reduced in the mould forming process of a bottle, the cracking caused by too rapid heat dissipation is avoided and the quality of the bottle is assured.

Description

technical field [0001] The invention belongs to the technical field of glass moulds, in particular to a mold for manufacturing glass containers. Background technique [0002] Glass containers such as glasses, cosmetic bottles, all kinds of pickle bottles, vases, wine bottles, beverage bottles, etc., the production of such glass bottle containers needs to rely on corresponding bottle molds. About the bottle mold that glass container is used, there is no lack of in the patent document, wherein the mold around making beer bottle and wine bottle is in the majority, typical as the mold that publication number CN101298355A recommends making glass container usefulness, this patented technical scheme is in a pair The upper part of the half-mold of the bottle and corresponding to the surrounding of the bottle neck cavity are provided with insulation holes to increase the temperature around the bottle neck cavity so that the liquid material, that is, the glass melt, can be evenly dist...

AI Technical Summary

Problems solved by technology

[0005] There is no doubt that the cracking of the mouth of the wine bottle and the incomplete blowing of the glass melt are caused by the own defects of the mold structure, because during the molding process of the wine bottle, the part near the mouth is directly in contact with the outside air, so that The heat dissipation is accelerated and the cooling speed is increased, but the existing bottle mold cannot meet the requirements of suppressing the excessive heat dissipation of the bottle mouth

The technical solutions provided by the above-mentioned CN101298355A and CN101298356A have contributed to the overall insulation of the bottleneck, but the problem of excessive heat dissipation at the bottleneck still exists
