The invention discloses needle, the nozzle head of a kind of needle structure for carrying guide-localization, including nozzle body, lift；Nozzle head is fixed on inside nozzle body, and needle is fixed on inside nozzle head；There is needle guide portion, a cast gate Feng Jiao area, cast gate Feng Jiao areas are in the bore of the bore less than needle guide portion in below needle guide portion and cast gate Feng Jiao areas inside said nozzle head；Needle includes guiding backflash, guide section, envelope and pours section；The lateral surface that backflash runs through needle is oriented to, guide section, which is in, to be oriented to below backflash and matched with needle guide portion, and envelope pours section and is in below guide section and matched with cast gate Feng Jiao areas.The present invention can solve how to make nozzle body with nozzle head concentric fit degree height and cause the technical problem of fluid reflux.
Description
Technical field
It is used to seal the needle structure for carrying guide-localization for pouring work the present invention relates to a kind of injection molding art.
Background technology
The structure that the current completion envelope in plastic shaping pours work generally comprises nozzle body, heater, three portions of nozzle head
Part, the design structure of current nozzle body and nozzle head can not coordinate well, and after the completion of envelope pours work segment fluid flow without
Method is back in nozzle head.
The content of the invention
The purpose of the present invention is to improve a kind of needle structure for carrying guide-localization, and how solution makes nozzle body and nozzle head
Concentric fit degree is high and causes the technical problem of fluid reflux.
The needle structure of guide-localization is carried, includes needle, the nozzle head of nozzle body, lift；Nozzle head is fixed on spray
Inside mouth body, needle is fixed on inside nozzle head；There is a needle guide portion, a cast gate envelope to pour inside said nozzle head
Area, cast gate Feng Jiao areas are in the bore of the bore less than needle guide portion in below needle guide portion and cast gate Feng Jiao areas；Needle bag
Include guiding backflash, guide section, envelope and pour section；The lateral surface that backflash runs through needle is oriented to, guide section, which is in, to be oriented under backflash
Match just and with needle guide portion, envelope pours section and is in below guide section and matched with cast gate Feng Jiao areas.
There is heater inside the nozzle body.
The nozzle head also has a fluid zone, and the fluid zone is into turbination and above needle guide portion.
The guiding backflash is 2-4.
The 2-4 guiding backflash mutually runs through.
The guiding backflash is in contact with guide section so that guide section has corresponding breach.
The beneficial effects of the invention are as follows：Due to pouring section provided with guiding backflash, guide section, envelope on needle；In nozzle head
Portion has needle guide portion, a cast gate Feng Jiao area；Wherein being oriented to backflash is conducive to needle correct in motion process
Self- steering is positioned, and the plastics that needle moves downward centre can flow back in time, be easy to envelope to pour；Guide section is matched with needle guide portion,
Envelope is poured section and matched with cast gate Feng Jiao areas, is so conducive to needle correct self- steering positioning in motion process, in valve needle movements mistake
Cheng Zhong, envelope Jiao Duan Neng Hefengjiao area precise match.

Embodiment
It refer to the needle structure that guide-localization is carried in Fig. 1 to Fig. 8, figure, including nozzle body 1, a lift
Needle 2, a nozzle head 3.
Nozzle head 3 is fixed on inside nozzle body 1, and needle 2 is fixed on inside nozzle head 3；The inside of nozzle body 1 has heater
4, the main structure body of the nozzle body 1 is prior art, needle 2 and the core innovative point that nozzle head 3 is this case, below to needle 2
Emphasis description is carried out with nozzle head 3.
The inside of nozzle head 3 has needle guide portion 31, cast gate Feng Jiao areas 32, a fluid zone 33, the fluid
Area 33 is into turbination and in the top of needle guide portion 31, and the fluid zone 33 is used at the flowing of fluid, cast gate Feng Jiao areas 32
Bore in the lower section of needle guide portion 31 and cast gate Feng Jiao areas 32 is less than the bore of needle guide portion 31；Cast gate Feng Jiao areas 32 are used for
The envelope of fluid is poured and realizes that the concentricity of nozzle head 3 and needle 2 keeps same position while pouring section 23 with envelope and matching.Needle guide portion
31 are used for the guiding movement of needle 2.
Needle 2 includes being oriented to backflash 21, guide section 22, seals and pour section 23；It is oriented to the quantity of backflash 21 and may be selected 2-4 simultaneously
Mutually run through the lateral surface of needle 2, guide section 22, which is in, to be oriented to the lower section of backflash 21 and matched with needle guide portion 31, and envelope pours section
23 are in the lower section of guide section 22 and are matched with cast gate Feng Jiao areas 32.Certainly, being oriented to backflash 21 also can be without mutually running through, its
Fluid reflux can be played a part of.Above-mentioned guiding backflash 21 be in contact with guide section 22 so that guide section 22 have pair
The breach 24 answered, fluid just flows back from above-mentioned breach 24.
Fig. 5 is refer to, the figure is shown when needle 2 lifts, and the plastic liquid of melting is sequentially entered from the side of needle 2
Fluid zone 33, needle guide portion 31, cast gate Feng Jiao areas 32.
Fig. 6 is refer to, when the figure is shown needle 2 and moved downward, due to needle 2 and indefinite and nozzle head 3 is with one heart,
Now, the guide section 22 of needle 2 just contradicts the needle guide portion 31 of nozzle head 3, so plays guide effect to needle 2, real
Now last center alignment.
Fig. 7 is refer to, the figure is shown when needle 2 is moved downward, when the envelope of needle 2 pours section 23 and nozzle head 3
When cast gate Feng Jiao areas 32 are contacted, now needle 2 needs to continue to move downward, and the fluid in cast gate Feng Jiao areas 32 can only be to needle 2
Backflash 21 is oriented to back up.
Fig. 8 is refer to, the figure is shown needle 2 and moves to rearmost position, realize that encapsulation completes work.
