Neck mould being beneficial to exhausting

Abstract

The invention relates to a neck mould being beneficial to exhausting. The neck mould consists of a male mould and a female mould. Joint surfaces on the male neck mould and the female neck mould are protruded from a plane portion. A gas guiding groove is vertically arranged on each joint surface. A plurality of transversally-arranged exhausting grooves A are disposed on joint surface portions on the two sides of each gas guiding groove. The gas guiding groove communicates an interior of a bottle neck cavity with external air through the exhausting groove A. A neck ring is arranged on and matched with the neck mould, wherein a clearance is formed between the neck ring and a joint line on the neck mould which is corresponding to the neck ring. Compared with a neck mould in the prior art, phenomena that bottle necks are not round in shape and are not uniform in sizes can be avoided through arrangement of the gas guiding groove and the exhausting grooves A on the joint surfaces and the clearance formed between the neck mould and the neck ring so that production quality and production efficiency of glass bottles are increased. Meanwhile, by means of arrangement of the joint surfaces, a match area of joint surfaces and a match tolerance in the prior art are reduced. The joint surfaces are manufactured in a manner of being higher than the plane portion so that a clearance is provided for enabling gas to be exhausted to the exterior through the exhausting groove A.

Description

technical field [0001] The invention relates to glass bottle rough blank processing accessories, in particular to a die which is beneficial to exhaust. Background technique [0002] like figure 1 As shown, in the manufacturing process of glass bottles, it is necessary to pass the melted glass frit 1 through the cooperation of the blank mold 2, the mouth mold 3, the mouth ring 4, the core (not shown) and the bulkhead (not shown). The glass bottle is preliminarily formed. Among them, the mouth mold 3 is used to form the glass bottle mouth, mainly forming the overall shape, size, bottle mouth thread, etc. of the bottle mouth. It is one of the important molds for manufacturing glass bottles. Specifically, as figure 2 and image 3 As shown, the mouth die 3 is formed by the cooperation of the male die 33 and the female die 34, and the die cavity 32 connecting up and down is provided on the plane part 31 of the male die 33 and the female die 34, and the two die cavities 32 are ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, because the inside of the die is relatively closed, when the glass frit enters the die, the glass frit squeezes the gas in the die to form a vacuum inside the die, and the sealing of the die causes the glass bottle The bottle mouth is not round, the size of the mouth is not equal, etc. These problems seriously affect the production quality of glass bottles

[0004] In order to solve the above-mentioned problem that the quality of the glass bottle is seriously affected due to the relatively closed inside of the mouth mold, it is currently envisaged to set an exhaust groove on the mouth mold to realize exhaust inside the mouth mold, so as to solve the problem that the bottle mouth is not round and the size is not equal. The problem is to improve the overall quality of the glass bottle, so the present invention proposes a mouth die that can improve the production quality of the glass bottle and is conducive to exhaust.
