The mouth mould
Technical field
The utility model relates to bottle crude green body processing accessory, particularly a kind of mouth mould for bottle moulding punching press assembly.
Background technology
The processing of bottle crude green body generally is divided into the method for blowing and two kinds of methods of press-and-blow process, and press-and-blow process is that bottle is pressed once by the punching press assembly, then blows once and can form the bottle crude green body; Existing ranks bottle-making machine punching press assembly is comprised of mouth mould, mouthful circle and drift three parts, but existing punching press assembly can cause a lot of problems because structure design is reasonable not, has influence on the processing quality of bottle.
Such as the mouth mould is mounted on blank mould, in the course of processing, mouthful mould is upset often, because the mouth mould is all straight up and down up and down, so than being easier to encounter blank mould, thereby have influence on processing.
The utility model content
The utility model has overcome above-mentioned the deficiencies in the prior art, and a kind of mouth mould of novelty is provided, and this mouthful mould has improved shape, the structure of mouthful mould, thereby makes it can not encounter blank mould when upset.
The technical solution of the utility model is achieved in that
A kind of mouthful of mould is provided with in the mouth mould for the mobile through hole of drift turnover, and a mouthful mould surrounding convexes with the set ring of embracing pincers in order to connect, is provided with the first arc slope on the top of set ring, and the diameter of the first arc slope increases from top to bottom gradually; Be provided with the second arc slope in the bottom of set ring, the diameter of the second arc slope increases from down to up gradually.
More smooth for drift is moved, drift is played guide effect, as preferably, in mouth mould bottom punch ingress, the internal diameter ecto-entad of the first through hole is from large to small.
Adopted the beneficial effects of the utility model of technique scheme to be:
The utility model is provided with the first arc slope on the top of mouth mould set ring, is provided with the second arc slope in the bottom of set ring; Thereby the top and the bottom that make set ring have formed respectively the rounding off of taper, avoid encountering blank mould when upset.

Embodiment
Embodiment of the present utility model is as follows:
Embodiment: a kind of mouthful of mould, as shown in Figure 1, be provided with in mouth mould 1 for the mobile through hole 4 of drift turnover, mouthful mould 1 surrounding convexes with the set ring 8 of embracing pincers in order to connect, the diameter that is provided with the first arc slope 13, the first arc slopes 13 on the top of set ring 8 increases from top to bottom gradually; The diameter that is provided with the second arc slope 14, the second arc slopes 14 in the bottom of set ring 8 increases from down to up gradually.
At mouth mould bottom punch entrance 11 places, the internal diameter ecto-entad of the first through hole 4 from large to small.
