I-Hollow blow molding i-extrusion noma ukubunjwa komjovo okutholwe i-semi-melting plastic billet yezinhlobonhlobo ze-abrasive enomumo, i-abrasive evaliwe, ku-billet ngokuya ngokufutha komoya, ukuze ihlangane nodonga lwe-abrasive, ngemva kokupholisa. isikhunta kanye nezandla eziyize.Ingasetshenziselwa ukukhiqizwa kwamafutha adliwayo, iziphuzo, iziphuzo, izinongo, ubisi nezinye izinto zokupakisha ukudla ngamabhodlela epulasitiki, izinhlobonhlobo ze-annular, isikwele, ezibunjiwe kanye nemiphongolo yezicabha, amathini kanye neminye imisebenzi yezandla engenalutho.
I-Hollow blow molding iwukuguqulwa kwepulasitiki yepulasitiki yepulasitiki engenalutho efakwe ethuluzini lokugaya, ukucindezelwa komoya endaweni engenalutho, ukuyiqhumisa, kuyenze ibe seduze nodonga lwesigxobo sesikhunta, emva kokupholisa ukuze uthole ukwakheka okuthile kokukhiqizwa kwezingxenye zepulasitiki ezingenalutho nokucubungula. .Ngokusho indlela yokubumba ayifani, ingahlukaniswa ngezindlela ezine.
1, ukubunjwa kwe-extrusion blow
1 - Ikhanda lomshini wokukhipha 2 - ukubumba i-blow 3 - i-tubular billet 4 - i-air compression boiler blow tube 5 - izingxenye zepulasitiki
I-extruder yokuqala ekhishwe i-tubular billet;Khipha ingxenye yokuqedela ipayipi eligoqayo bese ulifaka ethuluzini lokugaya ngenkathi kushisa, vala izinhlangothi zesobunxele nesokudla zolunye uhlobo lokugoqa lungenalutho lwethuluzi lokugaya elivulekile;
Khona-ke ku-concave bafe phakathi kokucindezelwa komoya, ukuze i-billet ivuthele futhi ihlanganiswe odongeni lwangaphakathi lwetafula le-die core;
Ekugcineni, ngemva kokugcinwa kwengcindezi, isiqandisi nokwakheka, kungasusa ukucindezelwa komoya kanye nesikhunta ukuze kukhishwe izingxenye zepulasitiki.
I-Extrusion blow molding mold design ilula, ukutshalwa kwezimali kwephrojekthi kuncane, ukusebenza kwangempela kulula kakhulu, kufanelekile ukubumba okuhlukahlukene kwepulasitiki okungenalutho.I-Extrusion blow molding amaphutha akulula ukushuba odongeni olulinganayo, izingxenye zepulasitiki zidinga ukucutshungulwa ngemuva kokususwa kwe-burr.
2, umjovo igalelo ukubumba
1 — Imbobo yomjovo 2 — Uhlobo lwenaliti alunalutho 3 — Isisekelo sesikhunta esingenalutho (core) 4 — Iheater kagesi 5 — isikhunta esivuthela 6 — izingxenye zepulasitiki
Isikhunta sokuqala somjovo emshinini womjovo ukwenza uhlobo olungenalutho lwe-spectral lungabi nalutho;
Khona-ke i-core kanye ne-billet ithuthelwa ekubunjweni kwe-blow molding, i-core ingenalutho futhi udonga lwangaphakathi luqukethe i-microporous plate;
Kamuva, isikhunta sikhiyiwe futhi sicindezelwe kusuka epayipini le-core shaft emoyeni, ukuze okungenalutho kuphephe futhi kuhlanganiswe odongeni lwangaphakathi lwe-concave mold surface yethuluzi eliqhumayo;
Ekugcineni, ngemva kokugcinwa kwengcindezi, isiqandisi nokwakheka, kungasusa ukucindezelwa komoya kanye nesikhunta ukuze kukhishwe izingxenye zepulasitiki.
Inzuzo ye-injection blow blowing ukuthi ubukhulu bodonga bezingxenye zepulasitiki bulinganiswe kahle ngaphandle kokundiza, ngaphandle kokukhiqiza nokucubungula.Ngenxa yohlobo lwenaliti engenalutho, ngakho-ke alikho ilunga elingaphansi kwezingxenye zepulasitiki, amandla acindezelayo aphezulu, ukukhiqizwa okuphezulu nokusebenza kahle kokukhiqiza, kodwa ukutshalwa kwezimali kwephrojekthi kwemishini nemishini kanye namathuluzi abrasive kukhulu kakhulu, ikakhulukazi inqwaba. ukukhiqizwa kwezingxenye zepulasitiki ezincane neziphakathi.
3, umjovo welula igalelo ukubumba
1 - Umjovo womjovo 2 - isikhunta somjovo 3 - i-mandrel elula (i-boiler blow tube) 4 - isikhunta sokuqhuma 5 - izingxenye zepulasitiki
Umjovo wokubumba igalelo lokushaya kuyindlela yokukhiqiza kanye nokucubungula ukuthi i-spectral yokubumba yomjovo ingenalutho ishisiswe kumazinga okushisa afanele ngaphansi kwephuzu lesixazululo bese ifakwa ethuluzini eliqhumayo.I-extension rod iqala yenziwa ukwelula i-radial bese ingena ekubunjweni komfutho womoya.
Ngemva kokunwebeka izingxenye zepulasitiki ezibunjiwe zokucaca kwayo, amandla acindezelayo okumelana nomthelela, amandla angaphezulu, ukuqina kokugoba kanye nezici zokumelana nomusi kuvame ukuba ngcono kakhulu.Umjovo wokubumba igalelo lempahla ejwayelekile kakhulu amabhodlela amanzi amaminerali e-polyester.Umjovo wokubunjwa kokushaywa komjovo ungahlukaniswa ngendlela ye-billet eshisayo kanye nendlela ye-billet ebandayo izindlela ezimbili zokubumba.
Eyokuqala umjovo ekubumbeni eyize spectral blank;Hambisa i-billet endaweni yokubumba yokwelula nokushaya ukuze wenze ukwelula nokubumba ukufutheka;Ngemuva kokugcinwa kwengcindezi, isiqandisi ngaphandle kwesikhunta sikhiphe izingxenye zepulasitiki.
Lolu hlobo lwendlela yokubumba lusindisa ukushisisa kabusha kwe-billet ebandayo futhi yonga amandla.Ngaphezu kwalokho, uhlelo lwe-billet kanye nokubunjwa kwe-stretch blow kwenziwa emshinini ofanayo kanye nemishini, ehlala endaweni encane, ilungele ukuthuthukiswa okuqhubekayo kokukhiqiza nokukhiqiza, futhi inezinga eliphezulu lobuchwepheshe obuzenzakalelayo.
Cold billet stretch blow blow molding umjovo wezinga lokushisa elihle le-billet endaweni yokushisa efanelekile bese uyibeka ekubumbeni i-blow molding ukwenza ukubumba kwe-stretch blow.Lapho ukhetha indlela ebandayo yokwenza i-billet, umjovo we-billet kanye nokubunjwa kwe-stretch blow of izingxenye zepulasitiki kwenziwa emishinini nasemishini ehlukene ngokulandelana.Ngaphambi kokubunjwa kokushaywa okunwebekayo, ukuze kunxeshezelwe ukushisa okukhishwe isiqandisi se-billet, ukushisa kwesibili kufanele kwenziwe ukuze kuqinisekiswe ukubunjwa kokushaywa kwe-billet.
Amashidi ama-4 epulasitiki wokubumba
Ishidi lepulastiki elifutha umjovo lokubumba umjovo noma ukubumba kwe-extrusion ishidi lepulasitiki lokushisisa, kwenze kube thambile, ku-concave isikhunta, kukhiyelwe phakathi kwepuleti lepulasitiki ekuminyanisweni komoya futhi wenze izingxenye zepulasitiki ezingenalutho.
