Mould for manufacturing bottle and jar glass containers

Abstract

The invention discloses a mould for manufacturing bottle and jar glass containers, belonging to the technical field of glass moulds. The mould comprises a pair of bottle semi-moulds and a bottle bottom mould, wherein each bottle semi-mould is provided with a bottle semi-mould cavity and a group of axial exhaust holes; and the bottle bottom mould is matched with the bottoms of the bottle semi-moulds and is provided with a matching boss for being matched with a matching groove of the bottle bottom mould. The mould is characterized in that the group of axial exhaust holes are communicated with the matching groove of the bottle bottom mould; the top of each axial exhaust hole is provided with a screw plug for ensuring that the axial exhaust hole is isolated from the outside; an aspirating connecting cavity is formed at the center of the bottle bottom mould and the side opposite to the bottle semi-moulds; and the matching boss is provided with aspirating holes communicated with the matching groove of the bottle bottom mould and the aspirating connecting cavity, the amount of the aspirating holes is equal to that of the exhaust holes, and each aspirating hole corresponds to one of the axial exhaust holes. The mould has the advantages that neck and shoulder parts can be ideally cooled, and the thickness uniformity of the neck and shoulder parts of the glass containers can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of glass moulds, and in particular relates to a mold used for manufacturing bottle-type glass containers. Background technique [0002] The molds defined above by the applicant for the manufacture of bottle-type glass containers refer specifically to the molds used to manufacture glass containers with neck and shoulders, such as beer bottles, red wine bottles, various condiment bottles and Soda bottles and more. In the process of manufacturing glass containers with neck and shoulders from bottle-type glass molds, the deformation of the neck and shoulders is the most difficult problem for the industry because the wall thickness of the neck and shoulders of the glass container is much thicker than that of the bottle body. . Although people have already reached a consensus on the causes of neck and shoulder deformation, so far there is no ideal countermeasure. The reason for the deformation of the neck part ...

Problems solved by technology

[0009] However, Figure 3 is still limited during actual use, because it is a natural form of heat convection rather than forced convection

[0010] The applicant believes that in order to improve the cooling effect (speed) of the neck and shoulders in the prior art, the design idea is focused on the half-mold of the bottle, which is biased because I have neglected to pay attention to the bottle bottom mold. However, the bottle bottom mold (the industry is accustomed to call it the bottom mold) is just an important part of the whole set of glass molds. The problem is how to use the bottle bottom mold to cool the neck and shoulders of the half mold of the bottle. Participation is exactly what the industry is looking for
