Description
Technical field
This utility model relates to a kind of injection machine air-assisted extrusion nozzle arrangements, belongs to injection machine technical field.
Background technology
Gas assisted injection molding technology is on the basis of traditional injection molding technology and TECHNOLOGY OF STRUCTURAL FOAM MOLDING,
Combine the new plastics forming technique that respective advantage grows up, used more and more extensive in recent years.Gas assists
The intake method that injection moulding large-scale plastic parts injection mould generally uses is air inlet in mold cavity, i.e. uses air inlet valve technology
Gas is injected by the valve being arranged in mold cavity, and valve position will be close proximity to cast gate, so that gas flow direction is with molten
Body flow direction is consistent.But using this valve to need to use special mold cavity, structure is complex, use not side
And relatively costly just,.
Utility model content
For solving the technical problem that prior art exists, this utility model provides a kind of simple in construction, easy to use, gas
Mouth and injection-moulding nozzle Integral design, applied widely, the injection machine air-assisted extrusion nozzle arrangements of low cost.
For achieving the above object, the technical scheme that this utility model is used is a kind of injection machine air-assisted extrusion nozzle knot
Structure, including the valve body being arranged on injecting machine material tube, the front end of described valve body is provided with nozzle, sets between described nozzle and valve body
It is equipped with pad, in described valve body, is provided with spool, be provided with spring between described spool and pad, described nozzle is additionally provided with
One-way air inlet mouth.
Preferably, between described nozzle and valve body, all use between valve body and injecting machine material tube threaded.
Preferably, described valve body is variable-diameter structure, and is internally provided with draw-in groove, the trapezoidal structure of described spool, and installs
In draw-in groove.
Compared with prior art, this utility model has following technical effect that this utility model simple in construction, design are closed
Reason, uses valve and injection-moulding nozzle Integral design, easy to use and with low cost, applied widely, it is adaptable to various injections
Machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, with
Lower combination drawings and Examples, are further elaborated to this utility model.Should be appreciated that concrete reality described herein
Execute example only in order to explain this utility model, be not used to limit this utility model.
As it is shown in figure 1, a kind of injection machine air-assisted extrusion nozzle arrangements, including the valve body 2 being arranged on injecting machine material tube 1,
The front end of valve body 2 is provided with nozzle 3, between nozzle 3 and valve body 2, all use between valve body 2 and injecting machine material tube 1 threaded,
It is provided with pad 4 between nozzle 3 and valve body 2, in valve body 2, is provided with spool 5, between spool 5 and pad 4, be provided with spring 6, spray
One-way air inlet mouth 7 it is additionally provided with on mouth 3.Valve body 2 is variable-diameter structure, and is internally provided with draw-in groove 8, the trapezoidal structure of spool 5, and
It is arranged in draw-in groove 8.In use, injecting machine material tube ejection melt, melt backs down spool, makes melt spray into mould through nozzle
Intracavity.After being molded, injecting gas, under gas effect, spool self-locking by one-way air inlet mouth, gas enters mold cavity,
Easy to operate and applied widely.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, all should wrap in this utility model model
In enclosing.
