Description
Technical field
The utility model relates to a kind of film blow mold, especially a kind of one-shot forming air-cushion film blow mold.
Background technology
At present, household electrical appliance, from garage, the shock resistance buffering packages such as kitchen, furniture and paint product goods, mainly adopt expanded material.Expanded material floor space is large, transport inconvenience, and reclaim difficulty, after being used to complete, easily cause white pollution.And the air cushion that adopts plastic sheeting to prepare, in the time not inflating, floor space is little, and transport storage is very convenient, and recovery is convenient, does not pollute the environment.But make the film that air cushion is used, need it to there is certain intensity and higher toughness, and because air cushion uses for inflation is rear, the heat sealability to film and air-tightness also there is higher requirement.
Tradition extrusioning blowing process, because Material Strength is limited, generally produce the hollow products such as air cushion by the tape casting etc., as China Patent No. CN201210254252.8, disclose a kind of method of utilizing series connection hollow blow molding to produce Large Hollow Container and comprised the steps: according to the size of the size selection mould of the container that will manufacture; Material feeding, injects extruder by the raw material of producing hollow container; Raw material by high-temperature fusion, mixing, is extruded tubulose hollow type base in extruder; Blowing, the length of the tubular, hollow parison that extruder is extruded reaches after required length, extruder stops extruded parisons, tubular, hollow parison is inserted between the first half module and the second half module, the upper gas hole of extruder stretches into the hollow position of one end of tubular, hollow parison, the lower gas hole of extruder stretches into the hollow position of the other end of tubular, hollow parison, extruder by upper gas hole, lower gas hole to the tubular, hollow parison hollow blow molding of connecting; Matched moulds; The demoulding.Adopt this invention can produce the uniform Large Hollow Container of wall thickness.
Along with the appearance of the modified films such as multi-layer co-extruded film, the material capability of film is greatly improved, as China Patent No. ZL201120118884.2, a kind of air-cushion film for container is disclosed, it is characterized in that: the described air-cushion film for container is seven-layer co-extrusion film, and it is followed successively by from top to bottom: metallocene PE layer, the first adhesive layer, nylon layer, the second adhesive layer, low density polyethylene layer, the first linear low density polyethylene layer and the second linear low density polyethylene layer.This utility model product is the air-cushion film for container, and puncture resistance is high, good toughness, heat sealability is good, cost is low.
Extrusion-blown modling method is because equipment operating is simple, and cost is lower, can use the material after modulation or co-extrusion, makes air-cushion film.If Fig. 1 is that the top view of conventional films blow mold and Fig. 2 are as shown in the A-A partial sectional view of 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.
But great majority are produced the film blow mold of air-cushion film mostly in traditional moulds process simple refit, need post forming, and product structure are simple in production process, cannot meet the demand of market diversification.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of one-shot forming air-cushion film blow mold.
The utility model solves the problems of the technologies described above taked technical scheme: a kind of one-shot forming air-cushion film blow mold, comprise a mouthful mould, plug and some cores, wherein, plug axle center is provided with plug pore, core axle center is provided with core pore, it is characterized in that: described mouth die sleeve is located at mandrel outer, core cross section is trapezoidal, upper base is interior concave arc, bottom is evagination circular arc, uniformly at intervals between mouth mould and plug, entirety is spliced into annulus between two, and between three, gap forms air-cushion film runner.
Can the connected annulus air cushion of one-shot forming by extrusion-blown modling, enhance productivity, reduce the loss of material in post forming.
On the basis of such scheme, dashpot is carved with in described core bottom, forms buffer runner.
Material is after buffer runner, and film is extruded more even, is conducive to improve the quality of products.
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: one-shot forming, raise the efficiency, cost-saving, reduce the loss of material in post forming; Simple in structure, easy to operate.
