Yas yog thawj rhuab thiab melted nyob rau hauv lub cua sov chim chim ntawm ib tug txhaj tshuaj molding tshuab. Tom qab ntawd, tsav los ntawm cov ntsia hlau lossis plunger ntawm lub tshuab txhaj tshuaj molding, nws nkag mus rau hauv pwm kab noj hniav los ntawm kev txhaj tshuaj nozzle thiab pwm qhov rooj kaw lus. Cov yas txias thiab hardens, solidifying rau hauv cov khoom kawg thaum demolding. Nws cov qauv feem ntau muaj cov molding Cheebtsam, lub rooj vag system, kev taw qhia Cheebtsam, ib tug ejection mechanism, ib tug kub tswj system, ib tug venting system, thiab cov khoom txhawb nqa. Cov khoom siv feem ntau yog yas pwm steel qauv, feem ntau yog ua los ntawm cov qauv hlau, cov cuab yeej carbon steel, cov cuab yeej alloy steel, thiab siab - steel ceev. Kev txhaj tshuaj molding feem ntau tsuas yog tsim nyog rau kev tsim cov khoom siv thermoplastic. Cov khoom siv yas uas tsim los ntawm kev txhaj tshuaj molding yog siv dav, los ntawm cov khoom siv niaj hnub mus rau ntau yam kev siv tshuab, cov khoom siv hluav taws xob, thiab cov khoom siv thauj mus los. Nws yog txoj kev siv ntau tshaj plaws hauv kev tsim khoom yas.
Yas Moulds
Yas pwm yog cov cuab yeej siv hauv kev lag luam plastics, ua ke nrog cov yas molding tshuab, muab cov khoom yas kom tiav cov duab thiab qhov ntev. Vim muaj ntau hom yas thiab cov txheej txheem ua, thiab qhov sib txawv ntawm cov yas molding tshuab thiab cov khoom yas, cov pwm yas kuj tuaj yeem muaj ntau hom thiab cov qauv.
Basic Introduction
Cov yas pwm ua ke siv rau compression molding, extrusion molding, txhaj molding, tshuab moulding, thiab qis-foaming molding feem ntau muaj cov kab noj hniav pwm nrog cov kab noj hniav sib txawv, muaj li ntawm cov kab noj hniav pwm sib dhos phaj, kab noj hniav pwm, thiab kab noj hniav pwm sib dhos clamping phaj; thiab lub punch pwm nrog cov tub ntxhais sib txawv, muaj xws li cov punch los ua ke hauv paus phaj, cov khoom xuas nrig, cov punch sib dhos clamping phaj, kab noj hniav txiav - tawm cov khoom, thiab sab txiav - tawm cov phaj sib dhos. Cov pwm pwm pwm, kab noj hniav pwm, thiab cov pwm pwm pwm sib koom tes thiab hloov. Nws tuaj yeem ua cov khoom yas ntawm cov duab sib txawv thiab ntau thiab tsawg. Hauv kev lag luam plastics, nws yog siv ua ke nrog cov yas molding tshuab los muab cov khoom yas kom tiav cov duab thiab qhov ntev. Vim muaj ntau hom yas thiab cov txheej txheem ua, thiab qhov sib txawv ntawm cov yas molding tshuab thiab cov khoom yas, cov pwm yas kuj tuaj yeem muaj ntau hom thiab cov qauv.
Nrog rau txoj kev loj hlob sai ntawm kev lag luam plastics thiab kev txhim kho txuas ntxiv ntawm lub zog thiab lwm yam khoom ntawm kev dav - lub hom phiaj thiab engineering plastics, daim ntawv thov ntau yam ntawm cov khoom yas yog txuas mus ntxiv, thiab kev noj cov khoom yas kuj nce ntxiv.
Plastic pwm yog ib qho cuab yeej los tsim cov khoom yas. Nws muaj ob peb qhov chaw, uas ua ke tsim ib kab noj hniav molding. Thaum lub sij hawm txhaj tshuaj molding, cov pwm yog clamped rau ntawm lub tshuab txhaj tshuaj molding, molten yas yog txhaj rau hauv molding kab noj hniav, txias thiab solidifies nyob rau hauv cov kab noj hniav, ces lub sab sauv thiab sab pwm cais, thiab cov khoom yog ejected los ntawm pwm kab noj hniav ntawm lub ejection system. Thaum kawg, cov pwm kaw dua rau lub voj voog txhaj tshuaj molding tom ntej; tag nrho cov txheej txheem txhaj tshuaj molding yog cyclical.
Feem ntau, cov pwm yas muaj ob ntu: lub pwm txav thiab pwm ruaj khov. Cov pwm txav yog mounted rau ntawm qhov txav platen ntawm lub tshuab txhaj tshuaj molding, thiab cov pwm ruaj khov yog mounted rau ntawm cov platen ruaj khov. Thaum lub sij hawm txhaj tshuaj molding, qhov txav thiab ruaj khov pwm nyob ze los tsim cov kab noj hniav thiab kab noj hniav; Thaum lub sij hawm qhib pwm, qhov txav thiab ruaj khov pwm cais kom tshem tawm cov khoom yas.
Txawm hais tias cov qauv ntawm cov pwm tuaj yeem sib txawv heev vim qhov sib txawv ntawm hom thiab cov khoom ntawm cov yas, cov duab thiab cov qauv ntawm cov khoom yas, thiab hom kev txhaj tshuaj molding tshuab, cov qauv hauv paus tseem zoo ib yam. Lub pwm feem ntau muaj cov rooj tog zaum, qhov ntsuas kub, qhov chaw molding, thiab cov khoom siv. Ntawm cov no, qhov system gating thiab molding qhov chaw yog cov khoom ncaj qha mus rau cov yas thiab sib txawv nyob ntawm seb cov yas thiab cov khoom. Lawv yog cov complex, feem ntau sib txawv, thiab yuav tsum tau lub siab tshaj plaws ntawm nto tiav thiab precision nyob rau hauv yas pwm ua.
Lub rooj vag kaw lus hais txog txoj kev ntws ntawm cov yas ua ntej nws nkag mus rau hauv kab noj hniav los ntawm lub nozzle, nrog rau cov neeg khiav dej num tseem ceeb, qhov dej txias txias, cov ceg khiav, thiab lub rooj vag. Moulding qhov chaw xa mus rau ntau yam khoom uas zoo li cov khoom, nrog rau cov pwm txav, ruaj pwm, kab noj hniav, core, moulding pas nrig, thiab vents.
Tsav los ntawm cov thev naus laus zis siab thiab daim ntawv thov kev xav tau ntawm kev lag luam pillar, kuv lub teb chaws cov yas pwm kev lag luam tau tsim ib qho kev lag luam loj loj, los ntawm cov khoom siv raw khoom thiab kev ua / cov khoom siv rau kev lag luam hauv qab xws li tshuab, tsheb, maus taus, khoom siv hauv tsev, hluav taws xob thiab kev sib txuas lus, thiab cov khoom siv hauv tsev. Kev lag luam yas pwm yog kev vam meej.
