Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
Detailed description of the invention, is expanded on further the present invention.
As shown in Figure 1, 2, a kind of injection molding machine injection device, including material pipe 1, (accompanying drawing is not drawn to be provided with screw rod in described material pipe 1
Go out), the exit of described material pipe 1 is provided with nozzle 2, and described nozzle 2 includes the nozzle seat 21 being connected with material pipe 1, by connecting
Nozzle head 23 that bar 24 is connected with nozzle seat 21 and the nozzle connector 22 being arranged between nozzle seat 21 and nozzle head 23, described
Between nozzle head 23 with nozzle connector 22, the extension spring 25 by arranging along nozzle head 23 axis direction is connected；Described nozzle seat 21
Having the first flow 211 of cylinder, described nozzle head 23 has the 3rd runner, and described 3rd runner includes conical section 231 He
The cylindrical section 232 being connected with conical section 231, described nozzle connector 22 includes the nozzle core adapted with conical section 231 shape
221 and the connecting tube 222 that is connected with nozzle core 221, nozzle core 221 has with by connecting tube 222 and the 3rd flow passage
The second runner 2211, the two ends of described connecting tube 222 cylindrical section 232 with first flow 211 and the 3rd runner respectively slides
Coordinate；
Also include that the heater 3 for adding the plastics that heat fusing is condensate in nozzle, described heater 3 include arranging
Heat-insulation layer 31 outside nozzle seat 21 and nozzle head 23 and the electromagnetic heating coil 32 being wrapped in outside described heat-insulation layer 31, nozzle seat
21 and nozzle head 23 be made up of ferroalloy, electromagnetic heating coil 32 is connected with electromagnetic heating controller.When nozzle 2 is preheated, logical
Crossing electromagnetic heating controller makes Electromagnetic Heating pass to high-frequency high-voltage in now enclosing, and then makes nozzle seat 21 and nozzle head 23 the highest
Speed heating, reaches rapid Melting And Solidification plastics in nozzle 2, thus significantly shortens when starting injection machine nozzle 2 every time
Preheating time, improve production efficiency.
Operation principle: as it is shown in figure 1, before not being molded, under the pulling force effect of extension spring 25, the nozzle core of nozzle connector 22
221 match with the conical section 231 of the 3rd runner, thus are blocked by the circulation passage of molten material.As schemed, 2 show, during injection, and molten material
Being under pressure, the molten material being positioned at the second runner 2211 is gone out downwards, and under the counteracting force of molten material, nozzle connector 22 is overall
Upwards jack-up, thus the circulation passage of molten material is opened, molten material injects injection through cylindrical section 232 and the conical section 231 of the 3rd runner
In mould.After being molded, being applied to the distress resolves of molten material, extension spring 25 pulls nozzle connector 22 to reset, by molten stream all
Road blocks, it is thus possible to prevent from producing wire drawing prolong flow phenomenon because molten material continues to flow out, and then improves product quality.Work as injection machine
Shut down relatively long, when solidification has plastics in nozzle, before injection, in electromagnetic heating coil 32, pass to high-frequency high-voltage, nozzle seat
21 and nozzle head 23 at a high speed heating voluntarily, thus Melting And Solidification plastics in nozzle 2 rapidly.
As the further improvement of such scheme, the most sheathed on described nozzle seat 21, connecting tube 222 and nozzle head 23
Have first, second and third connection dish 212,223,233, the two ends of described connecting rod 24 be connected with first and third respectively dish connect 212,
233, the two ends of described extension spring 25 are connected dish, 223,233 connections respectively with second and third, arrange first, second and third connection dish, convenient
Installing and connect, the effect of limited location gone back by the second connection dish 223 simultaneously, can prevent nozzle connector 22 entirety when injection from upwards moving
It is dynamic apart from excessive, so that nozzle core 221 is ejected from the cylindrical section 232 of first flow 211.
As the further improvement of such scheme, it is evenly arranged with multiple described second runner along nozzle core 221 circumference
2211, preferably four, the direction that fluid penetrates from the second runner 2211 is less than described cone with the angle of nozzle core 221 axis direction
The angle of the normal direction of the inwall of shape section 231 and nozzle core 221 axis direction, anti-after the second runner 2211 injection of molten material
Active force is bigger at the component along nozzle core 221 axis direction, so that nozzle connector 22 is quickly by upwards jack-up,
To open molten stream circulation passage.
As the further improvement of such scheme, the material of described nozzle connector 22 is copper, and copper has the highest heat conduction
Coefficient, when the nozzle seat 21 at nozzle connector 22 two ends and nozzle head 23 self-heating, heat can promptly pass to centre
Nozzle connector 22, thus plastics in rapid melting nozzle connector 22.
As the further improvement of such scheme, described heat-insulation layer 31 is aluminium foil layer, on nozzle seat 21 and nozzle head 23
Being wound with multilayer aluminum layers of foil, aluminium foil has good heat reflection effect, and aluminium foil material is the thinnest, is suitably arranged on nozzle.
The ultimate principle of the present invention and principal character and advantages of the present invention are more than shown and described, for this area skill
For art personnel, it is clear that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and without departing substantially from the present invention spirit or
