Abstract
A kind of film blow mold, comprise a mouthful mould (2) and plug (1), wherein, plug (1) axle center is provided with passage (11), it is characterized in that: described mouth mould (2) is set in outside plug (1), makes to form petal-shaped runner (3) between a mouthful mould (2) and plug (1).The utility model has the advantage of: the in the situation that of identical runner girth, size is much smaller than traditional round ring-type runner mold.
Description
Technical field
The utility model relates to a kind of film blow mold, is mainly used in the production field of extrusion blow molding film.
Background technology
Inflation film is widely used in packing of product industry and agricultural production.If Fig. 1 is as shown in the top view of conventional films blow mold and A-A partial sectional view that Fig. 2 is conventional films blow mold, conventional films blow mold comprises band traditional moulds mouth mould 2 ' and traditional moulds plug 1 ', traditional moulds plug 1 ' axle center is provided with traditional moulds passage 11 ', traditional moulds mouth mould 2 ' is set in outside traditional moulds plug 1 ', form circular runner 3 ', material is by circular runner 3 ' extrusion and blow molding.Meanwhile, most of mouthfuls of moulds are provided with adjusting device, for finely tuning the thickness of extrusion film.
The architecture advances of film blow mold is of a great variety, as China Patent No. ZL 201010584290.0, discloses a kind of die geometry of plastic blow molding machine, belongs to blowing field of mechanical technique.Comprise core rod, die orifice circle and the die sleeve with die sleeve chamber, the bottom of die orifice circle and die sleeve is fixed, die sleeve and cylinder block are fixed, core rod is positioned at die sleeve, and be fixedly connected with the oil cylinder post of oil cylinder, be characterised in that: also include an elastic collar and at least one elastic collar thixotroping device for forcing elastic collar to be out of shape, elastic collar is positioned at the outside of described core rod, between the inwall of this elastic collar and the outer wall of core rod, form and be useful on for material base by Xi road, and the top of this elastic collar probes in die sleeve chamber, and bottom supporting is in the bottom of the inwall of described die orifice circle, elastic collar thixotroping device is fixed on die orifice circle and/or die sleeve, and contact with the outer wall of elastic collar.Advantage: both helped avoid waste of material, and be of value to again the manufacturing cost that reduces plastic containers.
Yet most of architecture advances only for film extrude the product demands such as thickness and the charging number of plies, its film blow mold still adopts traditional circular runner.Circular runner in actual use, exists die size excessive, the technical problem that floor space is wide.
And for example China Patent No. ZL 200920126692.9, a kind of abnormal shape die geometry for the preparation of extrusion-blown modling industrial part is disclosed, comprise a mouthful mould main body, on the inwall of mouth mould main body, be provided with at least one longitudinal stream material groove, the groove bottom of described stream material groove is curved surface smooth arc-shaped surface I inwardly, the utility model is for the wall unevenness problem causing due to extrusion-blown modling industrial part shape, local location at extruder draught animals mould is offered groove, thereby increase the wall thickness of parison local location, obtain the parison of abnormal shapeization, further obtain finished product product, compare with traditional handicraft, the prepared product wall thickness of the utility model is even, the use amount of its raw material reduces greatly, saved cost, and owing to having increased the local particularly wall thickness of inflection place, the withstand voltage impact strength of product integral body is improved greatly, reduced stress concentrated, thereby extended the service life of product, the utility model can be widely used in the associated components manufacture of automobile, motorcycle and logical machine.
Although above-mentioned patent counterpart mould shape is changed, goal of the invention and practical structures are still to rely on circular runner, do not change circular runner die size excessive, the technical problem that floor space is wide.
Those skilled in the art, for the problems referred to above, provide a kind of film blow mold, and the in the situation that of identical runner girth, size is much smaller than traditional round ring-type runner mold.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of film blow mold, and the in the situation that of identical runner girth, size is much smaller than traditional round ring-type runner mold.
The utility model solves the problems of the technologies described above taked technical scheme: a kind of film blow mold, comprise mouthful mould and plug, wherein, plug axle center is provided with passage, wherein: described mouth die sleeve is located at mandrel outer, forms petal-shaped runner between mouth mould and plug.
Petal-shaped flow passage structure is in the situation that runner girth is identical, and its maximum gauge is far smaller than circular runner, so the size of mouthful mould is dwindled greatly, effectively reduces the floor space of establishing mould.
Described mouth mould can be provided with adjusting device, and adjusting device can regulate part or the integral width of air-cushion film runner, so as to regulating the thickness of extrusion film.
The utility model has the advantage of: the in the situation that of identical runner girth, size is much smaller than traditional round ring-type runner mold.

2---mouthful mould; 3---petal-shaped runner.
The specific embodiment
Referring to Fig. 3 is that top view of the present utility model, Fig. 4 are that B-B partial sectional view of the present utility model, Fig. 5 are C-C partial sectional view of the present utility model:
As in Figure 3-5, a kind of film blow mold, comprises mouthful mould 2 and plug 1, and plug 1 axle center is provided with passage 11, and wherein, plug 1 axle center is provided with passage 11, wherein: described mouth mould 2 is set in outside plug 1, at mouth mould 2 and 1 of plug, forms petal-shaped runner 3.
Described mouth mould can be provided with adjusting device, and adjusting device can regulate part or the integral width of air-cushion film runner, so as to regulating the thickness of extrusion film.
The utility model designs by petal-shaped flow passage structure, and in the situation that runner girth is identical, its maximum gauge is far smaller than circular runner, so the size of mouthful mould is dwindled greatly, effectively reduces the floor space of establishing mould.
