Abstract
The invention discloses a nozzle of an injection molding machine. The nozzle of the injection molding machine comprises a nozzle body, a nozzle guide rod and an injection screw. The nozzle body is arranged on the nozzle guide rod in a sleeving mode through a transverse guide groove. The injection screw is inserted in the nozzle guide rod. The nozzle body is composed of a cylinder ring on the left side, a trapezoid cylinder ring in the middle and a cylinder ring on the right side. A plurality of suction holes are formed in a ring body of the cylinder ring on the right side of the nozzle body. A transverse first air cylinder is fixed to the center of the injection screw. A piston rod of the first air cylinder is connected with a cleaning body of a cylinder. A second air cylinder is fixed to the outer side wall of the nozzle guide rod. A piston rod of the second air cylinder is connected with the right end face of the nozzle body. The nozzle of the injection molding machine has the advantages that melt left in the nozzle can be squeezed and sucked out in time, and the probability that the nozzle is blocked is lowered.
Description
Technical field:
The present invention relates to a kind of nozzle, be especially a kind of injection molding machine nozzle.
Background technology:
Injection machine is that one utilizes mould for plastics, and thermoplastic or heat fixing character plastics are made the main former of variously-shaped plastic. Need during its work to melt solid feed, then pass through feed pipe and nozzle injection to die for molding. In injection-moulding device conventional at present, generally upon completion of the injection, still remaining the raw material of molten state in nozzle, particularly when material viscosity is relatively low, phenomenon is even more serious. And the molten plastic being trapped in the spray-hole place of nozzle easily blocks spray-hole, blocking post processing is got up cumbersome, can affect normal production.
It is necessary to provide a kind of new technical scheme for above-mentioned technical problem.
Summary of the invention:
It is an object of the invention to for prior art not enough, it is provided that the melt of the timely nozzle clearing internal residual of a kind of energy, reduce the injection molding machine nozzle of the blocking of nozzle.
For reaching above-mentioned purpose, the invention provides a kind of injection molding machine nozzle, a kind of injection molding machine nozzle, including nozzle, nozzle guide rod, injection screw; Described nozzle cage is located on nozzle guide rod; Described injection screw is plugged in the inside of nozzle guide rod; Described nozzle is made up of the cylinder ring in left side, the trapezoidal cylinder ring at middle part and the cylinder ring on right side; Cylinder ring ring body on the right side of described nozzle offers some suction holes; Described injection screw center is fixed with the first horizontal cylinder; The described piston rod of the first cylinder is connected with the clean body of cylindrical shape; Described nozzle guide rod lateral wall is fixed with the second cylinder; The piston rod of described second cylinder is connected with nozzle right side; The central shaft conllinear of the cylinder ring on the left of the central shaft of described clean body and nozzle.
Preferred as technique scheme, the stroke of described second cylinder is more than the diameter of suction hole.
Preferred as technique scheme, described clean body diameter is less than the diameter of the cylinder ring on the left of nozzle.
Preferred as technique scheme, described suction hole is at least provided with 4.
Preferred as technique scheme, the stroke of described first cylinder is more than the length of the cylinder ring on the left of nozzle.
The beneficial effects of the present invention is: can extrude in time and the melt of sucking-off nozzle interior residual, reduce the blocking of nozzle.

Fig. 1 is the cross-section structure schematic views of the present invention;
Fig. 2 is the cross-section structure schematic views during duty of the present invention;
In figure, 10, nozzle; 11, suction hole; 20, the second cylinder; 30, nozzle guide rod; 40, injection screw; 41, the first cylinder; 42, clean body.
Detailed description of the invention:
Below in conjunction with accompanying drawing the present invention done and describe in detailed below. For sake of convenience, following " on ", D score, "left", "right" consistent with the direction, upper and lower, left and right of accompanying drawing itself.
As shown in Fig. 1～2, a kind of injection molding machine nozzle, including nozzle 10, nozzle guide rod 30, injection screw 40; Described nozzle 10 is set on nozzle guide rod 30; Described injection screw 40 is plugged in the inside of nozzle guide rod 30; Described nozzle 10 is made up of the cylinder ring in left side, the trapezoidal cylinder ring at middle part and the cylinder ring on right side; Cylinder ring ring body on the right side of described nozzle 10 offers some suction holes 11; Described injection screw 40 center is fixed with the first horizontal cylinder 41; The described piston rod of the first cylinder 41 is connected with the clean body 42 of cylindrical shape; Described nozzle guide rod 30 lateral wall is fixed with the second cylinder 20; The piston rod of described second cylinder 20 is connected with nozzle 10 right side; The central shaft conllinear of the cylinder ring on the left of the central shaft of described clean body 42 and nozzle 10.
The stroke of described second cylinder 20 is more than the diameter of suction hole 11.
Described clean body 42 diameter is less than the diameter of the cylinder ring on the left of nozzle 10.
Described suction hole 11 is at least provided with 4.
The stroke of described first cylinder 41 is more than the length of the cylinder ring on the left of nozzle 10.
During real work, after nozzle 10 completes a shot, injection screw rod 40 can reach high order end, contact with nozzle guide rod 30 left side, now the second cylinder 20 startup makes nozzle 10 to left movement, makes nozzle 10 separate with nozzle guide rod 30, and now nozzle 10 forms suction line with gap meeting and the suction hole 11 of nozzle guide rod 30, then the first cylinder 41 startup makes clean body 42 to left movement, and the melt in the cylinder ring ring body of such nozzle 10 left end will be extruded; Then starting the blower fan (not shown) that is connected with suction hole 11, the remaining melt of nozzle 10 intracavity can be sucked out, thus can the interior melt remained of nozzle clearing, it is to avoid plug nozzle 10.
