Lub hauv paus ntsiab lus ua haujlwm ntawm kev txhaj tshuaj molding tshuab yog dab tsi? Dab tsi yog kev faib tawm ntawm lub tshuab txhaj tshuaj molding? Qee tus neeg muaj qhov teeb meem zoo li no, peb txhua tus paub tias lub tshuab txhaj tshuaj molding yog cov khoom siv tseem ceeb rau kev ua cov thermoplastics lossis thermosetting plastics rau hauv ntau cov duab ntawm cov khoom yas siv cov yas molding pwm.
Yog li dab tsi yog lub hauv paus ntsiab lus ntawm kev txhaj tshuaj molding tshuab, thiab kev tshuaj xyuas tom ntej:
Ua ntej, lub hauv paus ntsiab lus ntawm kev txhaj tshuaj molding tshuab
Kev txhaj tshuaj molding yog kev siv cov khoom siv thermophysical ntawm cov yas, cov khoom siv ntxiv rau hauv lub thoob los ntawm lub hopper, lub thoob sab nraud yog rhuab los ntawm lub nplhaib cua sov, cov khoom yog melted, thiab lub thoob yog nruab nrog ib tug ntsia hlau uas tsav kev sib hloov nyob rau hauv lub nplhaib. qhov kev txiav txim ntawm lub tshuab hluav taws xob sab nraud, thiab cov khoom siv yog nyob rau hauv qhov kev txiav txim ntawm cov ntsia hlau;
Thawb thiab compact raws cov ntsia hlau zawj rau pem hauv ntej, cov khoom yog maj mam plasticized, melted thiab homogenized nyob rau hauv lub dual ua ntawm sab nraud cua sov thiab ntsia hlau shearing, thaum cov ntsia hlau tig, cov khoom yog nyob rau hauv cov nyhuv ntawm kev sib txhuam thiab shear quab yuam ntawm cov ntsia hlau zawj, molten cov ntaub ntawv raug thawb mus rau lub taub hau ntawm cov ntsia hlau, tib lub sij hawm, cov ntsia hlau retreats nyob rau hauv cov tshuaj tiv thaiv ntawm cov khoom, ua rau lub taub hau ntawm cov ntsia hlau tsim ib qho chaw cia, ua tiav cov txheej txheem plasticization;
Tom qab ntawd, nyob rau hauv cov nyhuv ntawm piston thrust ntawm txhaj tshuaj lub tog raj kheej, ntsia hlau pas nrig nrog kev kub ceev, kev kub siab, cov khoom molten nyob rau hauv lub cia chamber yog txhaj rau hauv kab noj hniav ntawm pwm los ntawm nozzle, thiab cov khoom molten nyob rau hauv cov kab noj hniav yog nyob rau hauv cov nyhuv. clamping mechanism, tom qab solidification thiab teeb tsa, pwm qhib pwm nyob rau hauv cov nyhuv ntawm pwm clamping mechanism, thiab los ntawm ejector ntaus ntawv muab thiab los ntawm ejector ntaus ntawv, cov khoom tiav yog ejected thiab ntog los ntawm pwm.
Thib ob, kev faib tawm ntawm kev txhaj tshuaj molding tshuab
Raws li cov clamping qhov chaw thiab txhaj tshuaj qhov chaw configuration hom, muaj peb hom: kab rov tav, ntsug thiab kaum.
1. Kab rov tav txhaj tshuaj molding tshuab:
Kab rov tav txhaj tshuaj molding tshuab yog hom siv ntau tshaj plaws. Nws yog tus cwj pwm los ntawm qhov tseeb tias qhov nruab nrab ntawm kev txhaj tshuaj sib dhos yog concentric lossis zoo ib yam nrog qhov nruab nrab ntawm lub clamping sib dhos thiab yog tib yam rau hauv av installation. Nws qhov zoo yog qhov nruab nrab ntawm lub ntiajteb txawj nqus, kev ua haujlwm ruaj khov, kev txhim kho pwm, kev ua haujlwm thiab kev saib xyuas yog yooj yim dua, pwm qhib loj, occupies ib qhov chaw me me qhov siab, tab sis npog thaj tsam loj, loj, nruab nrab thiab me cov cav tov tau dav siv.
2. Vertical txhaj tshuaj molding tshuab:
Nws yog tus cwj pwm los ntawm kev sib dhos ntawm cov cuab yeej clamping thiab cov cuab yeej txhaj tshuaj nyob rau hauv ib txoj kab thiab perpendicular mus rau hauv av. Nws muaj qhov zoo ntawm me me hneev taw, yooj yim pwm sib dhos thiab disassembly, yooj yim ntxig installation, plasticizing ntawm cov ntaub ntawv poob rau hauv lub hopper ntau tusyees, yooj yim kom paub automation thiab tsis siv neeg kab tswj ntau lub tshuab. Qhov tsis zoo yog tias cov khoom ejection tsis yooj yim rau poob tawm, thiab feem ntau yuav tsum tau muab nws tawm manually lossis los ntawm lwm txoj kev, thiab nws tsis yooj yim rau kev ua tiav kev ua haujlwm tsis siv neeg thiab txhaj tshuaj ntawm cov khoom loj.
3. Angular txhaj tshuaj molding tshuab:
Cov axes ntawm chav txhaj tshuaj thiab cov cuab yeej clamping yog teem rau ib leeg. Raws li tus txheeb ze txoj hauj lwm ntawm lub centerline ntawm kev txhaj tshuaj los ua ke thiab lub installation puag nto, muaj kab rov tav hom, ntsug thiab kab rov tav hom: 1) kab rov tav hom, txhaj tshuaj los ua ke kab yog parallel rau lub hauv paus nto, thiab nruab nrab kab ntawm pwm. clamping los ua ke yog perpendicular rau lub hauv paus nto; 2) hom ntsug thiab kab rov tav, kab nruab nrab ntawm kev txhaj tshuaj sib dhos yog perpendicular rau lub hauv paus nto, thiab cov kab nruab nrab ntawm cov pwm clamping sib dhos yog sib npaug rau lub hauv paus nto. Qhov kom zoo dua ntawm lub kaum sab xis txhaj tshuab yog tias nws muaj qhov zoo ntawm ob qho tib si kab rov tav thiab ntsug txhaj tshuab, thiab tshwj xeeb tshaj yog haum rau pwm nrog asymmetrical geometry ntawm sab rooj vag.
Kev faib tawm ntawm kev txhaj tshuaj molding tshuab
Qhov tseeb, lub hauv paus ntsiab lus ntawm kev txhaj tshuaj molding tshuab yog zoo ib yam li cov koob txhaj tshuaj uas siv rau kev txhaj tshuaj, uas yog siv lub thrust ntawm cov ntsia hlau (los yog plunger) los txhaj cov yas yas (piv txwv li, viscous flow) yas rau hauv cov pwm kaw. kab noj hniav, thiab tau txais cov txheej txheem ntawm tau txais cov khoom tom qab kho thiab shaping.
