Abstract

The utility model discloses a kind of improved glass bottle bottle neck mould, core bar, choma and a mouthful mould main body, consist of, it is characterized in that: setting unit is divided bottleneck die cavity on choma, part bottleneck die cavity is positioned at the angle position place of bottom end face and the inner side-wall of choma; On core bar, be positioned at the outer side wall of core bar and be on the position of matching with part bottleneck die cavity, be provided with " R " angle transition arc of indent; With the join bottleneck die cavity of complete of described " R " angle transition arc and described part bottleneck die cavity.The utility model is effectively thoroughly eliminated the small stair of bottleneck, thereby not only eliminates bottle stopper resistance, can also produce power-assisted effect to bottle stopper.

Description

Improved glass bottle bottle neck mould

Technical field

The utility model relates to a kind of vial bottleneck mould, is mainly used in the moulding of conventional vial bottleneck.

Background technology

As shown in Fig. 1 and Fig. 1 a, the inner side-wall of current glass bottle opening has a small stair a, is commonly called as twoport in industry, exactly because the existence of this small stair a, when plug bottle stopper, can produce very large resistance, even also may scratch bottle stopper, thereby sealing in bottle is produced to hidden danger.

As shown in Figure 2 a and 2 b, bottleneck forming mould is comprised of core bar 1, choma 2, mouthful mould main body 3 three parts, the moulding of bottleneck is determined by the bottom end face of choma 1b and the bottom pass of core bar 1a completely, so solve the problem of bottleneck inwall small stair (twoport), the problem also how coordinating with core bar 1a with regard to the ring 1b that becomes to understand to burst.

As shown in Fig. 3 and Fig. 3 a, bottleneck die cavity 2a is intactly positioned on the bottom end face of choma 2, existence and the restriction of its manufacture craft due to choma 2 thickness own, the flat segments outer side wall of the bottleneck die cavity 2a on choma 2 bottom end faces and core bar bottom cannot be fitted completely and cause producing certain thickness step surface b, and the existence of this step surface b makes bottleneck form small stair a (twoport) on sidewall within it, as shown in Fig. 4 and Fig. 4 a.In order to reduce this step, be all as much as possible the thickness of boss b to be reduced, but thickness reduce easily to cause because insufficient strength produces piece, shows as and have more a fritter on bottleneck in the past; It is large that yet thickness becomes, and causes again step obvious, formed twoport.

Summary of the invention

The utility model, for avoiding the existing weak point of prior art, provides a kind of improved glass bottle bottle neck mould, can effectively thoroughly eliminate the small stair of bottleneck, thereby not only eliminate bottle stopper resistance, can also produce power-assisted effect to bottle stopper.

The utility model is that technical solution problem adopts following technical scheme:

A kind of improved glass bottle of the utility model bottle neck mould, by core bar, choma and a mouthful mould main body, formed, its constructional feature is: on described choma, setting unit is divided bottleneck die cavity, and described part bottleneck die cavity is positioned at the angle position place of bottom end face and the inner side-wall of choma;

On described core bar, be positioned at the outer side wall of described core bar and be on the position of matching with described part bottleneck die cavity, be provided with " R " angle transition arc of indent; With the join bottleneck die cavity of complete of described " R " angle transition arc and described part bottleneck die cavity.

The feature of the utility model improved glass bottle bottle neck mould is also: described connecting position is in the top of bottleneck die cavity.

Prior art is compared, and the beneficial effects of the utility model are embodied in:

1, the structure design that the utility model joins by " R " angle transition arc and part bottleneck die cavity, make bottleneck end face and inwall form R angle arc transition, thoroughly eliminated the small stair (twoport) of glass bottle opening inwall, from root, eliminated and coordinated the bad problem that affects stopping property with bottle stopper because of bottleneck inwall.

2, the utility model has greatly improved the work-ing life of choma, because be inevitable as long as choma inner side exists step, step to lack piece, falls piece; There is not step in new choma, so long as not serious wear, can change completely completely, saves production cost.

Embodiment

In the present embodiment, a kind of improved glass bottle bottle neck mould is comprised of core bar 1, choma 2 and a mouthful mould main body 3; As shown in Fig. 5 and Fig. 5 a, on choma 2, setting unit is divided bottleneck die cavity 2b, and part bottleneck die cavity 2b is positioned at the angle position place of bottom end face and the choma 2 middle inner side-walls of choma 2;

As shown in Fig. 6 and Fig. 6 a, on core bar 1, be positioned at the outer side wall of core bar 1 and be on the position of matching with part bottleneck die cavity 2b, be provided with " R " angle transition arc 1a of indent; As shown in Fig. 7 and Fig. 7 a, when choma 2 combines with core bar 1, with the join bottleneck die cavity of complete of " R " angle transition arc 1a and part bottleneck die cavity 2b, thereby make vial bottleneck end face and its inner side-wall form the round and smooth R angle transition structure as shown in Fig. 8 and Fig. 8 a, no longer produce step a or wedge angle, be beneficial to the sealing of bottle stopper; Improved the work-ing life of mould simultaneously.Preferably, connecting position is in the top of this bottleneck die cavity, and in actually operating, and the optional position that connecting position can be in complete bottleneck die cavity, as long as can be connected with the arc section of part bottleneck die cavity " R " angle transition arc.
