Mould for manufacturing glass container

Abstract

The invention provides a mould for manufacturing a glass container, belonging to the technical field of a glass mould. The mould comprises a pair of bottle half modules, wherein each bottle half module is provided with a joint close surface and a bottle mould chamber composed of a bottleneck chamber, a neck shoulder chamber, a bottle body chamber and a bottle bottom chamber; the joint close surface comprises a bottle opening matching region located at the chamber opening part of the bottleneck chamber, a middle matching region corresponding to the chamber opening part of the bottle body chamber, a bottle bottom matching region corresponding to the chamber opening part of the bottle bottom chamber, and a peripheral matching region located at the outer side of the middle matching region. The mould is characterized in that: the planes of the bottle opening matching region and the bottle bottom matching region are located at the same height, the plane of the middle matching region is lower than the plane of the bottle opening matching region, and the plane of the peripheral matching region is lower than the middle matching region. The mould provided by the invention has the advantages that: a matching area of the matching surface is reduced, the deformation amount of the mould in a work process is compensated, the production efficiency is improved, the service life is prolonged, and the resource is saved.

Description

technical field

[0001] The invention belongs to the technical field of glass moulds, in particular to a mold for making glass containers. Background technique

[0002] Glass containers such as glasses, cosmetic bottles, all kinds of pickle bottles, vases, wine bottles and beverage bottles, etc., all need to rely on a pair of bottle half molds that are matched face to face. As known in the industry, in the process of using glass molds to produce glass containers, molten glass frit at 1100°C is introduced into the cavity of the glass mold, and the mold temperature drops rapidly to 650°C within 3-6 seconds. In this process, because the glass mold material is subjected to factors such as growth, oxidation and thermal fatigue, glass container manufacturers often find that although the life of the glass mold has not yet ended, the mold has already deformed And seriously affect the use, even if it is to barely maintain the mold that continues to be used, it needs to be frequently ...
