Dab tsi yog qhov nozzle hauv kev txhaj tshuaj molding?

Dab tsi yog qhov nozzle hauv kev txhaj tshuaj molding?
1, Kev ua haujlwm ntawm lub nozzle
Lub luag haujlwm tseem ceeb ntawm lub nozzle thaum lub sijhawm txhaj tshuaj molding muaj xws li:
Kev xa cov yas yaj: Raws li ib txoj hauv kev rau cov yas yaj kom nkag mus rau hauv pwm, lub nozzle yuav tsum tau xyuas kom meej tias cov yaj tuaj yeem ntws tau zoo thiab ruaj khov kom ntseeg tau tias cov yas molding zoo.
Kev tswj cov yaj ntws: Los ntawm kev kho nws cov qauv sab hauv, lub nozzle tuaj yeem tswj tus nqi ntws, kev taw qhia, thiab ntws tus nqi ntawm cov yaj, yog li ua tiav kev tswj xyuas meej ntawm cov txheej txheem tsim.
Rwb thaiv tsev thiab rwb thaiv tsev: Lub nozzle yuav tsum muaj kev ua haujlwm zoo rwb thaiv tsev kom tiv thaiv kom tsis txhob muaj cua txias ntawm yaj thaum lub sij hawm thauj mus los. Nyob rau tib lub sijhawm, lub nozzle kuj yuav tsum muaj kev ua haujlwm rwb thaiv tsev kom tsis txhob muaj cua sov hloov mus rau lwm qhov ntawm lub tshuab txhaj tshuaj molding.
2, Hom nozzle
Raws li hom thiab txheej txheem ntawm kev txhaj tshuaj molding tshuab, nozzles tuaj yeem muab faib ua ntau hom, feem ntau suav nrog:
Qhib nozzle: haum rau cov yas yaj uas muaj viscosity tsawg, nrog rau cov yam ntxwv ntawm cov qauv yooj yim thiab kev saib xyuas yooj yim. Txawm li cas los xij, vim tias nws tsis muaj peev xwm tswj tau cov dej ntws kom raug, nws tsis haum rau high-precision molding.
Koob valve nozzle: tswj qhov ntws ntawm cov hlau molten los ntawm kev qhib thiab kaw lub koob valve, nrog rau qhov zoo ntawm kev tswj cov dej ntws thiab tiv thaiv cov hlau molten. Haum rau high-precision thiab siab thov txhaj tshuaj molding.
Kub khiav nozzle: Thaum siv ua ke nrog cov kub khiav, nws tuaj yeem ua tiav cov khoom siv tas li ntawm cov yas yaj thiab txhim kho kev tsim khoom. Lub caij no, vim qhov kub ntawm cov yaj hauv lub nozzle, nws tuaj yeem txo qhov kev ua tsis xws luag.
3, Cov ntsiab lus ntawm kev xaiv nozzle
Thaum xaiv lub nozzle, cov hauv qab no yuav tsum tau xav txog:
Cov hom yas thiab yaj viscosity: Cov yas sib txawv muaj qhov sib txawv yaj viscosity, thiab cov hom nozzle yuav tsum tau xaiv. Piv txwv li, rau cov yas uas muaj viscosity siab, koob valve nozzles los yog kub khiav nozzles yuav tsum tau xaiv.
Pwm qauv thiab qhov loj me: Cov qauv thiab qhov loj ntawm pwm ncaj qha cuam tshuam rau kev xaiv ntawm nozzles. Xaiv lub nozzle tsim nyog raws li txoj haujlwm, kom muaj nuj nqis, thiab qhov loj ntawm lub qhov rooj pwm.
Kev ua tau zoo thiab kev qhia tshwj xeeb ntawm kev txhaj tshuaj molding tshuab: Kev ua haujlwm thiab kev qhia tshwj xeeb ntawm kev txhaj tshuaj molding tshuab txiav txim siab siv ntau yam ntawm nozzles. Nws yog ib qho tsim nyog los xyuas kom meej qhov sib xws ntawm cov nozzle xaiv thiab lub tshuab txhaj tshuaj molding kom ua tiav qhov zoo tshaj plaws molding nyhuv.
4, Tej teeb meem thiab kev daws teeb meem
Thaum lub sij hawm txhaj tshuaj molding txheej txheem, tej zaum yuav muaj ib co teeb meem nrog lub nozzle, xws li thaiv, hnav, thiab cov khoom to. Txhawm rau daws cov teeb meem no, cov kev ntsuas hauv qab no tuaj yeem ua:
Nozzle blockage: Tsis tu ncua ntxuav lub nozzle tiv thaiv impurities thiab residue los thaiv cov channel. Lub caij no, ua tib zoo saib xyuas qhov ntsuas kub thiab viscosity ntawm cov yas yaj kom txo tau qhov kev pheej hmoo ntawm kev txhaws.
Nozzle hnav: Xaiv cov ntaub ntawv nozzle nrog kev hnav zoo kom ntev lub neej kev pab cuam ntawm lub nozzle. Thaum siv, ceev faj kom tsis txhob muaj kev txhaj tshuaj ntau dhau thiab ceev kom txo tau qhov hnav ntawm lub nozzle.
Qhov teeb meem leakage: Xyuas seb qhov chaw sib cuag ntawm lub nozzle thiab pwm yog nruj kom ntseeg tau tias kev sib khi zoo. Yog tias pom muaj qhov xau, lub foob yuav tsum tau hloov los yog lub nozzle txoj hauj lwm kho raws sij hawm.
5, Cov ntsiab lus
Raws li qhov tseem ceeb ntawm cov txheej txheem txhaj tshuaj molding, kev ua haujlwm thiab kev siv cov nozzles ncaj qha cuam tshuam rau molding zoo thiab kev ua haujlwm ntawm cov khoom yas. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv lub nozzle tsim nyog, ua hauj lwm txij nkawm, thiab sai sai daws teeb meem. Nrog rau kev nce qib ntawm cov thev naus laus zis thiab kev txhim kho txuas ntxiv ntawm cov txheej txheem, kev ua haujlwm thiab hom nozzles tseem yuav hloov kho tas li thiab nthuav dav, muab kev txhawb zog rau kev txhim kho ntawm kev txhaj tshuaj molding kev lag luam.
