Mould for manufacturing bottle and jar glass containers

Abstract

The invention discloses a mold for manufacturing glass containers of bottles and jars, which belongs to the technical field of glass moulds. It includes a pair of bottle half-molds, each bottle half-mold has a bottle half-mold cavity and a set of axial vent holes; There are matching bosses, and the matching bosses are matched with the matching grooves of the bottle bottom mold. Features: a group of axial vents communicate with the matching grooves of the bottle bottom mold, and there are holes on the top of each axial vent hole for use The screw plug that isolates the axial exhaust hole from the outside world forms an air extraction connection cavity in the center of the bottle bottom mold and on the side facing away from the half mold of the bottle, and an air extraction hole is opened on the mating boss, and the air extraction hole is connected to the bottom of the bottle. The mold fitting grooves communicate with each other, and also communicate with the air suction connection cavity. The number of air suction holes is equal to the number of axial exhaust holes, and each air extraction hole corresponds to one axial air exhaust hole. Advantages: It can ideally cool the neck and shoulders and ensure the uniformity of the thickness of the neck and shoulders of the glass container.

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
