Abstract
The utility model discloses a kind of blow mold, it includes swaging die, punch and heater, parison cavity is set in described swaging die, arranging punch in described parison cavity, described punch is hollow structure, and described punch is connected with gassing pipe, the surface of described punch is uniform arranges gas hole, arranging heater in the swaging die of the circumferencial direction of described parison cavity, the bottom of described parison cavity arranges injecting hole, and described injecting hole is connected with nozzle of injector.Through the plastic uniform wall thickness that this utility model injection-blow molding shapes, non-trimming, being not required to post-treatment, dry injection parison have the end, therefore bottom is not spelled and seam, and intensity is high, and production efficiency is high.
Description
Technical field
This utility model relates to mould production technical field, is specifically related to a kind of blow mold.
Background technology
It is blow molded a kind of plastic working method quickly grown.The tubular plastic parison that thermoplastic resin is extruded or injection moulding obtains, while hot, is placed in split cavity, is passed through compressed air after mold closing immediately in parison, make plastic parison inflation be close on mould inner wall, the cooled demoulding, i.e. obtain various hollow product.The manufacturing process of inflation film is in principle and hollow product blowing is quite similar, but it does not use mould, and from the angle of plastic processing technology classification, the moulding process of inflation film is generally listed in extrusion.Blow molding process during World War II, starts for producing Low Density Polyethylene bottle.In the later stage fifties, along with birth and the development of blow molding machine of high density polyethylene (HDPE), blow molding technology is widely applied.The volume of hollow container have employed computer control up to thousands of liters, some production.The plastics being applicable to blowing have polyethylene, polrvinyl chloride, polypropylene, polyester etc., and the hollow container of gained is widely used as industrial packaging container.
Utility model content
This utility model overcomes the deficiencies in the prior art, it is provided that a kind of intensity is good, the blow mold that production efficiency is high.
In view of the problems referred to above of prior art, according to an aspect of the present utility model, for solving above-mentioned technical problem, this utility model by the following technical solutions:
A kind of blow mold, it includes swaging die, punch and heater, parison cavity is set in described swaging die, arranging punch in described parison cavity, described punch is hollow structure, and described punch is connected with gassing pipe, the surface of described punch is uniform arranges gas hole, arranging heater in the swaging die of the circumferencial direction of described parison cavity, the bottom of described parison cavity arranges injecting hole, and described injecting hole is connected with nozzle of injector.
In order to this utility model is better achieved, further technical scheme is:
According to an embodiment of the present utility model, described heater is for adding heat pipe.
Compared with prior art, one of the beneficial effects of the utility model are:
Blow mold of the present utility model, through the plastic uniform wall thickness that injection-blow molding shapes, non-trimming, is not required to post-treatment, dry injection parison has the end, and therefore bottom is not spelled and seam, and intensity is high, and production efficiency is high.
Accompanying drawing explanation
For clearer explanation present specification embodiment or technical scheme of the prior art, below the accompanying drawing used required in the description to embodiment or prior art is briefly described, apparently, accompanying drawing in describing below is only to the reference of some embodiments in present specification, for those skilled in the art, in the case of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the blow mold structural representation according to one embodiment of this utility model.
Wherein, entitled corresponding to the reference in accompanying drawing:
1-swaging die, 2-parison cavity, 3-punch, 4-gassing pipe, 5-heater, 6-injecting hole, 7-nozzle of injector.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
As shown in Figure 1, Fig. 1 is the blow mold structural representation according to one embodiment of this utility model, a kind of blow mold, it includes swaging die 1, punch 3 and heater 5, in described swaging die 1, parison cavity 2 is set, in described parison cavity 2, punch 3 is set, described punch 3 is hollow structure, described punch 3 is connected with gassing pipe 4, the surface of described punch 3 is uniform arranges gas hole, in the swaging die 1 of the circumferencial direction of described parison cavity 2, heater 5 is set, the bottom of described parison cavity 2 arranges injecting hole 6, described injecting hole 6 is connected with nozzle of injector 7.
Described heater 5 is for adding heat pipe.
First injector is injected molten plastic in injection mould and is made parison；Punch 3 moves in blow molding die together with parison, and punch 3 is hollow and carries porose on wall；In the pipeline of plug, it is passed through compressed air, makes parison propel the price of and be affixed on the cavity wall of mould；Release compressed air after pressurize, cooling and shaping, and plastic is taken out in die sinking.Through the plastic uniform wall thickness that injection-blow molding shapes, non-trimming, being not required to post-treatment, dry injection parison have the end, therefore bottom is not spelled and seam, and intensity is high, and production efficiency is high.
In this specification, each embodiment uses the mode gone forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, identical similar portion cross-reference between each embodiment.
This utility model is described by multiple explanatory embodiment the most of the present utility model, but, should be appreciated that, those skilled in the art can be designed that a lot of other amendments and embodiment, and these amendments and embodiment will fall within spirit disclosed in the present application and spirit.
