Isikhunta sebhodlela esiphuzwayo sivunguza ngokwezifiso ukubunjwa kwe-hollow blow sikhishwa ku-extruder, kusesesimweni sokuthambisa kwe-tubular hot plastic billet yepulasitiki ekubumbeni, bese kuthi ngomoya ocindezelwe, ukusetshenziswa komfutho womoya ukwenza i-billet deformation. eduze kwesikhunta, ukuze ushaye emqaleni imikhiqizo emifushane engenalutho.
Ukwenza ngokwezifiso isikhunta sebhodlela lesiphuzo
I-Hollow blow molding isetshenziswe kabanzi ekukhiqizeni imikhiqizo ehlukahlukene yegobolondo elincanyana elingenalutho, iziqukathi zokupakisha zamakhemikhali nezinsuku zonke, kanye namathoyizi ezingane.
I-Hollow blow molding (okubuye kwaziwe ngokuthi i-blow molding) kuyindlela yokwenza imikhiqizo engenalutho ngokufutha imibungu encibilikayo eshisayo evalwe esikhunjini ngosizo lwengcindezi yegesi.Iyindlela yesithathu evamile yokucubungula ipulasitiki kanye nendlela yokubumba ipulasitiki ethuthuka ngokushesha.
Imikhiqizo ekhiqizwa umshini wokubumba ongenalutho idinga ukushuba kodonga olufanayo.Ngokuvamile, imikhumbi engenalutho engaphansi kuka-0.2L ayikwazi ukuhlonyiswa ngedivayisi yokulawula ukujiya kodonga olungenalutho.Kwezinye izimo, idivayisi yokulawula ukuqina kodonga olungenalutho kufanele icatshangelwe, ikakhulukazi emikhiqizweni yokubumba engenalutho enezingxenye eziyinkimbinkimbi.
Njengamanje, ukulawulwa kokuqina kodonga kuvame ukufezwa ngokushintsha imvume yomlomo phakathi kwesembozo sekhanda kanye ne-die core.Ngokwezimo ezihlukene zesembozo sekhanda kanye ne-die core, indlela yokulungisa yokususa izindebe nayo ihlukile.Ukunyakaza okuphezulu nangaphansi kwe-mold core ngokuvamile kuqhutshwa isilinda esisebenza nge-hydraulic.
Lapho umshini wokubumba umoya ophakathi nendawo ucubungula isitsha sepulasitiki esingenalutho esinomumo olula, singabonakala ngokushintsha uhlelo lwe-hydraulic.I-electro-hydraulic directional valve yamukela kuphela amandla noma isignali yamandla, ukuze isilinda se-hydraulic phezulu noma phansi, ibanga lokunyakaza kwe-hydraulic cylinder (okungukuthi, ukuguqulwa kokuvula isikhunta somlomo) yinati yomkhawulo ophezulu naphansi. isethi, isivinini sokunyakaza kwe-hydraulic cylinder by the flow valve throttling action set, isignali kagesi ye-electro-hydraulic directional valve control by the time relay control.
Le ndlela yokulawula ilula futhi ishibhile, kodwa umthetho wokushintsha ukujiya kodonga ulula, kunezinhlobo ezimbili kuphela zokushintshwa kokuqina kodonga, zingasetshenziswa kuphela ukukhama nokuphephetha isitsha esilula esingenalutho.
