Thaum 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, nws 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, cov txheej txheem gating thiab molding qhov chaw yog qhov chaw ncaj qha rau cov yas thiab sib txawv nyob ntawm cov yas thiab cov khoom; lawv yog cov nyuaj tshaj plaws, feem ntau sib txawv, thiab yuav tsum tau lub siab tshaj plaws ntawm nto tiav thiab precision nyob rau hauv pwm.
Kev txhaj tshuaj pwm yog cov cuab yeej tsim khoom yas; nws kuj yog ib qho cuab yeej uas muab cov khoom yas rau lawv cov qauv ua tiav thiab cov qhov ntev meej. Kev txhaj tshuaj molding yog ib txoj hauv kev siv rau kev tsim khoom loj ntawm tej yam nyuaj- zoo li qhov chaw. Tshwj xeeb, nws yog hais txog kev txhaj tshuaj molten yas nyob rau hauv kev kub siab rau hauv pwm kab noj hniav siv lub tshuab txhaj tshuaj molding, qhov uas nws yog ces txias thiab solidified kom tau cov khoom molded.
Pwm Cheebtsam: Thaum 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, nws 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. Lub qhov rooj kaw lus thiab molding qhov chaw yog cov khoom uas ncaj qha mus rau cov yas thiab sib txawv nyob ntawm seb cov yas thiab cov khoom tiav. Lawv yog cov feem ntau nyuaj, sib txawv, thiab yuav tsum tau lub siab tshaj plaws ntawm nto tiav thiab precision nyob rau hauv cov txheej txheem molding.
Kev txhaj tshuaj pwm muaj ob ntu: 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 ruaj yog mounted rau ntawm cov platen ruaj khov. Thaum lub sij hawm txhaj tshuaj molding, qhov txav thiab ruaj khov pwm nyob ze rau tsim lub rooj vag system thiab kab noj hniav. Thaum cov pwm qhib, cov pwm txav thiab ruaj khov sib cais kom tshem tawm cov khoom yas. Txhawm rau txo qis kev ua haujlwm hnyav ntawm pwm tsim thiab tsim, feem ntau cov pwm txhaj tshuaj siv cov qauv pwm.
Ib qho kev txhaj tshuaj molding ib ntus cais cov pwm txav thiab ruaj khov thaum qhib, tso cai rau cov yas kom tshem tawm. Qhov no yog hu ua ib qho kev sib cais pwm, tseem hu ua ob- phaj pwm. Nws yog qhov yooj yim tshaj plaws thiab feem ntau hom kev txhaj tshuaj pwm. Nws tuaj yeem tsim los ua ib qho - kab noj hniav txhaj pwm lossis ntau - kab noj hniav pwm raws li xav tau, thiab yog hom kev txhaj tshuaj pwm ntau tshaj plaws.
Ob chav parting nto txhaj pwm muaj ob qhov chaw sib cais. Piv rau ib feem ntawm qhov chaw txhaj tshuaj pwm, muab ob npaug rau qhov chaw txhaj tshuaj pwm ntxiv ib feem ntawm cov phaj txav nruab nrab (tseem hu ua lub phaj txav tau, uas yog lub tsev sprue, khiav, thiab lwm qhov chaw thiab cov khoom xav tau los ntawm cov pwm ruaj khov) mus rau qhov seem pwm. Yog li ntawd, lawv kuj tseem hu ua peb - phaj (tsav phaj, phaj nruab nrab, phaj tsau) txhaj pwm. Lawv feem ntau siv rau hauv ib qho -kab noj hniav lossis ntau- kab noj hniav txhaj pwm nrog qhov rooj noj mov. Thaum lub sij hawm qhib pwm, lub phaj nruab nrab cais tawm ntawm lub phaj ruaj khov ntawm qhov chaw ruaj khov ntawm cov ncej ntawm cov pwm ruaj khov kom tso cai rau cov khoom sib txuas ntawm lub rooj vag kom tshem tawm ntawm ob lub platens. Muab ob npaug rau qhov chaw txhaj tshuaj pwm muaj cov qauv tsim, cov nqi tsim khoom ntau dua, thiab kev ua haujlwm nyuaj, thiab feem ntau tsis siv rau molding loj lossis ntxiv - cov khoom yas loj.
Txhaj pwm nrog sab parting thiab cores - rub mechanisms yuav tsum tau siv cov cores txav los yog sliders thaum cov yas muaj qhov sab los yog sab recesses. Tom qab txhaj tshuaj molding, cov pwm txav ua ntej txav mus rau hauv ib qho kev ncua deb. Tom qab ntawd, ntu inclined ntawm tus pin khoov rau lub phaj pwm ruaj khov yuam tus slider txav mus rau sab nraud. Nyob rau tib lub sijhawm, ejector pas nrig ntawm lub tshuab demolding thawb lub ejector phaj, ua rau cov yas detach los ntawm cov tub ntxhais.
Txhaj pwm nrog cov khoom txav tuaj yeem ua pwm yuav tsum tau txav tau cov pwm pwm vim yog cov qauv tshwj xeeb ntawm cov yas. Cov khoom no muaj xws li txav tau punches, txav tau tuag, txav tau ntxig, txav tau threaded cores, lossis rings. Thaum lub sij hawm demolding, cov khoom no tuaj yeem raug tshem tawm los ntawm pwm nrog rau cov yas thiab tom qab ntawd sib cais los ntawm nws.
Tsis siv neeg unscrewing txhaj pwm rau threaded yas qhov chaw yuav tsum tsis siv neeg demolding. Rotatable threaded cores lossis rings tuaj yeem ntsia tau rau ntawm pwm. Qhov qhib kev txiav txim, kev sib hloov ntawm lub tshuab txhaj tshuaj molding, los yog ib qho khoom siv sib txuas tuaj yeem siv los tig cov tub ntxhais los yog lub nplhaib, yog li ejecting cov yas.
Runnerless txhaj moulds hais txog kev txhaj tshuaj pwm uas siv cov txheej txheem ntawm insulatingly cua sov tus khiav kom cov yas nyob rau hauv lub molten lub xeev ntawm lub txhaj tshuaj molding tshuab nozzle thiab cov kab noj hniav, thiaj li hais tias tsis muaj solidified cov ntaub ntawv los ntawm lub rooj vag system yog txhaj thaum lub pwm qhib thiab cov yas raug tshem tawm. Lub qub yog hu ua insulated runner txhaj pwm, thiab tom kawg yog hu ua kub khiav txhaj pwm.
