Mold for manufacturing glass container

Abstract

The invention relates to a mold for manufacturing a glass container and belongs to the technical field of glass molds. The mold comprises a pair of prototype half molds in the same shape and structure, wherein the prototype half molds are opposite to each other, and each prototype half mold is provided with a glass container rudiment forming cavity and a glass container rudiment mouth forming cavity formed by coarctation of one end of the glass container rudiment forming cavity. The mold is characterized in that a group of heat preservation holes in parallel to the glass container rudiment mouth forming cavity are formed in the prototype half molds and around cavity walls of the glass container rudiment mouth forming cavities at intervals, and heat preservation hole caps are arranged at orifices of the heat preservation holes. Since the heat preservation holes are formed in the prototype half molds and around the cavity walls of the glass container rudiment mouth forming cavities at intervals, the cooling speed of glass melt in a mouth of the glass container can be reduced, and the forming requirement of the high glass container with a small mouth size is met.

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 glass cups, cosmetic bottles, all kinds of pickle bottles, vases, wine bottles and beverage bottles, etc., the production of such glass bottle containers needs to rely on corresponding bottle molds. When using glass molds to make corresponding glass products, it is necessary to strictly control the temperature of the mold to ensure the appearance quality of the glass products. Technical information about this aspect can be seen in the published Chinese patent documents, which revolve around the production of beer bottles and There are many molds for wine bottles, typically such as the "mold for making glass containers" recommended by the publication number CN101298355A. The temperature is increased so that the liquid material, that is, the glass melt, is evenly distributed when...

AI Technical Summary

Problems solved by technology

After repeated observation and analysis by the applicant, the reason for the premature solidification of the glass melt is that when the glass frit is cut by scissors or similar utensils, it enters the mold cavity of the initial mold along the chute of the bottle making machine. , because the temperature at the front end of the glass frit is always the lowest, and the mold cavity of the preliminary mold is in the shape of an inverted trumpet, and the size of the bottle mouth is small, so after entering the cavity of the preliminary mold, the glass frit The cooling speed is extremely fast, which seriously affects the molding of the bottle neck

[0006] The above-mentioned technical problems have long puzzled the industry, especially in the patents and non-patent literature disclosed so far, there is no enlightenment to solve the technical problems
