Kwinkqubo yokuvuthela ukusetyenzwa komngundo, izinto eziya kuchaphazela imveliso ikakhulu ziquka ukuvuthela uxinzelelo, isantya sokuvuthela, umlinganiselo wokuvuthela kunye nobushushu obuvuthelayo.
Ukusetyenzwa kokubumba ukuvuthela
1. Kwinkqubo yokuvuthela, umoya oxinyiweyo unemisebenzi emibini: enye kukusebenzisa uxinzelelo lomoya oxinyiweyo ukwenza i-semi-molten tube billet ivuthele kwaye ibambelele eludongeni lwe-mold cavity ukwenza imo efunwayo;Okwesibini, idlala indima yokupholisa kwimveliso yokubumba i-Dongguan.Uxinzelelo lomoya luxhomekeke kuhlobo lweplastiki kunye nobushushu be-billet, elawulwa ngokubanzi kwi-0.2 ~ 1.0mpa.Kwiiplastiki ezine-viscosity ephantsi ye-melt kunye ne-deformation elula (njenge-PA kunye ne-HDPE), thatha ixabiso eliphantsi;Kwiiplastiki ezine-viscosity ephezulu ye-melt (efana ne-PC), amaxabiso aphezulu athathwa, kunye nobukhulu bodonga lwe-billet.Uxinzelelo lokuvuthela lukwanxulumene nomthamo weemveliso, iimveliso ezinomthamo omkhulu kufuneka zisebenzise uxinzelelo oluphezulu lokuvuthela, iimveliso ezinomthamo omncinci kufuneka zisebenzise uxinzelelo oluncinci lokuvuthela.Uxinzelelo olufanelekileyo lokuvuthela kufuneka lukwazi ukwenza ukubonakala kunye nomzekelo wemveliso ecacileyo emva kokwenza.
2, isantya sokuvuthela ukuze unciphise ixesha lokuvuthela, ukuze kube lula kwimveliso ukufumana ubukhulu obufanayo kunye nenkangeleko engcono, iimfuno zesantya esisezantsi sokuhamba emoyeni, ukuqinisekisa ukuba i-billet kwi-billet i-mold cavity ingaba yinto efanayo, ukwanda ngokukhawuleza, ukunciphisa ixesha lokupholisa kwi-mold cavity, kwaye kukulungele ukuphucula ukusebenza kwemveliso.Isantya somoya esisezantsi sinokuphinda siphephe uhlobo lwesiphumo se-Venduri kwi-billet kunye nokubunjwa kwe-vacuum yendawo, ukwenzela ukuba i-billet deflated phenomenon.Oku kunokuqinisekiswa ngokusetyenziswa kombhobho omkhulu wokuvuthela.
I-3, umlinganiselo wokuvuthela xa ubungakanani kunye nomgangatho we-billet uqinisekile, ubukhulu besayizi yemveliso, inkulu i-billet blowing ratio, kodwa iyancipha ubukhulu bemveliso.Ngokuqhelekileyo ngokohlobo lweplastiki, indalo, imilo kunye nobukhulu bemveliso, kunye nobukhulu be-billet ukumisela ubungakanani bomlinganiselo wokuvuthela.Ngokunyuka komlinganiselo wokuvuthela, ubukhulu bemveliso buba buncinci, kwaye amandla kunye nokuqina kuyancipha.Kwakhona kuba nzima ukwenza.Ngokubanzi, umlinganiselo wokuvuthela ulawulwa kwi-l
2-4) okanye njalo.
4. Ubushushu bokubumba ukubunjwa bunempembelelo enkulu kumgangatho weemveliso (ingakumbi umgangatho wembonakalo).Ngokuqhelekileyo ukuhanjiswa kweqondo lokushisa lokungunda kufuneka kube yinto efanayo, kangangoko kunokwenzeka ukwenza imveliso efanayo yokupholisa.Ubushushu bokubumba bunxulumene nohlobo lweplastiki, ubukhulu kunye nobukhulu beemveliso.Kwiintlobo ezahlukeneyo zeplastiki, kukho iiplastiki ezimbalwa (ibhotile yokubumba i-PC) ubushushu bokubumba kufuneka bulawuleke kumacandelo.
Ukusebenza kwemveliso kuye kwabonisa ukuba ubushushu bomngundo buphantsi kakhulu, emva koko ukunyuswa kweplastiki kwikliphu kuncitshisiwe, akukho lula ukuvuthela, ukwenzela ukuba imveliso iqiniswe kule nxalenye, kwaye kunzima ukuyifaka, kwaye i-contour kunye nepateni yendawo yemveliso ayicacanga;Ubushushu bomngundo buphezulu kakhulu, ixesha lokupholisa liyandiswa, umjikelo wemveliso uyanda, kwaye imveliso iyancipha.Ngeli xesha, ukuba ukupholisa akwanelanga, kuya kubangela ukuba imveliso idemoulding deformation, izinga lokuncipha liyenyuka, kwaye ukukhanya komphezulu kubi.Ngokuqhelekileyo kwiiplastiki ezinobunzima obukhulu be-molecular chain, iqondo lokushisa lokungunda kufuneka libe phezulu;Kwiiplastiki ezinamakhonkco amakhulu e-molecular flexible, ubushushu bokubumba kufuneka buncitshiswe.
Iimveliso zokubumba umgongxo kwixesha lokupholisa ngundo elide, injongo kukuqinisekisa ukuba imveliso uphole ngokupheleleyo, demoulding ngaphandle deformation.Ixesha lokupholisa ngokubanzi lixhomekeke kubukhulu, ubungakanani kunye nokumila kweplastiki, kunye nohlobo lweplastiki.Okukhona udonga lujiyile, kokukhona ixesha lokupholisa lide.Ixesha lokupholisa leemveliso ze-61PE ezinomthamo omkhulu wokushisa okhethekileyo lide kunelo leemveliso zePP ezinomthamo omncinci wobushushu obuthile obufana nodonga olufanayo.
5. Umjikelo wokubumba Ukubumba umjikelo wemveliso ubandakanya i-billet ye-extrusion, ukuvala ukufa, ukusika i-billet, ukuvuthela, ukuchithwa, ukuvula ukubumba, ukukhupha iimveliso kunye nezinye iinkqubo.Umgaqo wolu khetho lomjikelo kukunciphisa kangangoko kunokwenzeka phantsi kwesiseko sokuqinisekisa ukuba imveliso inokubunjwa ngaphandle kokuguqulwa, ukwenzela ukuba kuphuculwe ukusebenza kakuhle kwemveliso.
