Description
Technical field：
The present invention relates to a kind of nozzles, are especially a kind of injection molding machine nozzle.
Background technology：
Injection molding machine is a kind of using mould for plastics, thermoplastic or heat fixing character plastics is made variously-shaped
The main former of plastic products.It needs to melt solid feed during its work, then be arrived by feed pipe and nozzle injection
Die for molding.In currently used injection-moulding device, generally upon completion of the injection, the original of molten state can be still remained in nozzle
Material, particularly material viscosity than it is relatively low when, phenomenon is even more serious.And it is trapped in the appearance of the molten plastic at the spray-hole of nozzle
Easily block spray-hole, block post processing get up it is cumbersome, can influence normally to produce.
For above-mentioned technical problem, it is necessary to provide a kind of new technical solutions.
Invention content：
The purpose of the present invention is in view of the shortcomings of the prior art, provide it is a kind of can nozzle clearing internal residual in time melt,
Reduce the injection molding machine nozzle of the blocking of nozzle.
In order to achieve the above objectives, the present invention provides a kind of injection molding machine nozzle, a kind of injection molding machine nozzles, including nozzle, spray
Mouth guide rod, injection screw；The nozzle is set on nozzle guide rod；The injection screw is plugged in the inside of nozzle guide rod；Institute
Nozzle is stated to be made of the cylinder ring of the cylinder ring in left side, the trapezoidal cylinder ring at middle part and right side；Cylinder ring on the right side of the nozzle
Several suction holes is offered in ring body；The injection screw center is fixed with the first lateral cylinder；First gas
The piston rod of cylinder is connected with the clean body of cylindrical shape；The second cylinder is fixed on the nozzle guide rod lateral wall；Described
The piston rod of two cylinders is connected with nozzle right side；The central shaft of cylinder ring on the left of the central shaft and nozzle of the clean body
Collinearly.
As a preferred embodiment of the above technical solution, the stroke of second cylinder is more than the diameter of suction hole.
As a preferred embodiment of the above technical solution, the clean body diameter is less than the diameter of the cylinder ring on the left of nozzle.
As a preferred embodiment of the above technical solution, the suction hole is at least provided with 4.
As a preferred embodiment of the above technical solution, the stroke of first cylinder is more than the length of the cylinder ring on the left of nozzle.
The beneficial effects of the present invention are：The remaining melt of nozzle interior can be squeezed out and be sucked out in time, reduces the stifled of nozzle
Plug.
Description of the drawings：
Fig. 1 is the cross-section structure schematic views of the present invention；
Cross-section structure schematic views when Fig. 2 is the working condition of the present invention；
In figure, 10, nozzle；11st, suction hole；20th, the second cylinder；30th, nozzle guide rod；40th, injection screw；41st, the first gas
Cylinder；42nd, clean body.
Specific embodiment：
The present invention is done below in conjunction with the accompanying drawings and is described in detailed below.For sake of convenience, following " on ", " under ", " left side ",
" right side " is consistent with the upper and lower, left and right direction of attached drawing in itself.
As shown in Fig. 1~2, a kind of injection molding machine nozzle, including nozzle 10, nozzle guide rod 30, injection screw 40；The nozzle
10 are set on nozzle guide rod 30；The injection screw 40 is plugged in the inside of nozzle guide rod 30；The nozzle 10 is by left side
The cylinder ring composition of cylinder ring, the trapezoidal cylinder ring at middle part and right side；It is offered in the cylinder ring ring body on 10 right side of nozzle
Several suction holes 11；40 center of injection screw is fixed with the first lateral cylinder 41；First cylinder 41
Piston rod is connected with the clean body 42 of cylindrical shape；The second cylinder 20 is fixed on 30 lateral wall of nozzle guide rod；It is described
The piston rod of second cylinder 20 is connected with 10 right side of nozzle；The central shaft of the clean body 42 and the cylinder in 10 left side of nozzle
The central shaft of ring is conllinear.
The stroke of second cylinder 20 is more than the diameter of suction hole 11.
42 diameter of clean body is less than the diameter of the cylinder ring in 10 left side of nozzle.
The suction hole 11 is at least provided with 4.
The stroke of first cylinder 41 is more than the length of the cylinder ring in 10 left side of nozzle.
In actual work, after nozzle 10 completes a shot, injection screw rod 40 can reach left end, with nozzle guide rod 30
Left side contacts, and the second cylinder 20 startup at this time makes nozzle 10 that nozzle 10 be made to be detached with nozzle guide rod 30, sprayed at this time to left movement
The gap of mouth 10 and nozzle guide rod 30 can and suction hole 11 form suction line, then the first cylinder 41 start make clean body 42 to
Left movement, the melt in the cylinder ring ring body of such 10 left end of nozzle will be extruded；Then start what is connect with suction hole 11
Wind turbine (not shown), the remaining melt of 10 intracavitary of nozzle can be sucked out, thus can remaining melt in nozzle clearing, avoid blocking up
Fill in nozzle 10.
