Mould for manufacturing bottle glass vessels

Abstract

The invention provides a mould for manufacturing bottle glass vessels, belonging to a glass mould. The mould comprises a pair of bottle semi-moulds which are oppositely arranged and provided with a semi-mould cavity respectively. The mould is characterized in that valve holes are reserved on positions of the bottle semi-moulds, correspond to the neck shoulders of the bottle semi-moulds respectively, and are communicated with the bottle semi-mould cavities; air valves are arranged in the valve holes, and are fixed with the bottle semi-moulds; exhaust holes communicated with the valve holes are reserved on the bottle semi-moulds respectively, extend to the tops of the bottle semi-moulds from the bottoms of the bottle semi-moulds and the valve holes and are communicated with the outside. In the technical scheme, when the bottle glass vessel with the neck shoulder is manufactured, gas between the neck shoulders of the mould and glass solution can be exhausted from the exhaust holes through the valve holes and the air valves to ensure that the glass solution is in plump state at the neck shoulder position of the bottle neck shoulders, and the deformation of the bottle neck shoulders can be inhibited finally.

Description

technical field [0001] The invention belongs to the technical field of glass moulds, and in particular relates to a mold used for making bottle-type glass containers. Background technique [0002] The molds defined by the applicant above for making bottle-type glass containers refer specifically to molds for processing glass containers with shoulders, such as beer bottles, red wine bottles, soda bottles, and the like. In the process of processing glass containers with necks and shoulders from bottle glass molds, the deformation of the neck and shoulders of bottles and cans is the most difficult problem for the industry. Although people have long recognized the reasons for the deformation of the neck and shoulders, there is no good solution so far. The reason for the deformation of the neck part is that during the last blow molding (blowing the glass prototype into a glass bottle product), the speed is fast, and the gas inside the cavity cannot be quickly removed, and the pa...

AI Technical Summary

Problems solved by technology

It can be seen that, in not limited to the patent application schemes listed above, no technical information that can be used for reference to avoid deformation at the neck and shoulder of the bottle is given.
