Inqubo yokubumba yomjovo isebenzisa isikhunta, ngokuvamile esenziwe ngensimbi noma i-aluminium, njengamathuluzi angokwezifiso.Isikhunta sinezingxenye eziningi, kodwa singahlukaniswa sibe izingxenye ezimbili.Ingxenye ngayinye inamathiselwe ngaphakathi komshini wokubumba umjovo futhi ingxenye engemuva ivunyelwe ukushelela ukuze isikhunta sivuleke futhi sivalwe eduze kwesikhunta.umugqa wokuhlukanisa.Izingxenye ezimbili eziyinhloko zesikhunta yi-mold core kanye ne-mold cavity.Lapho isikhunta sivaliwe, isikhala esiphakathi komgogodla wesikhunta kanye nesigxobo sesikhunta sakha ingxenye yesikhala, esizogcwaliswa ngepulasitiki encibilikisiwe ukuze kwakhiwe ingxenye oyifunayo.Ngezinye izikhathi kusetshenziswa isikhunta esinezimbotshana eziningi, lapho amahhafu esikhunta amabili enza izimbotshana eziningana ezifanayo.
Isisekelo sesikhunta
I-mold core kanye ne-mold cavity ngayinye ifakwe kusisekelo sesikhunta, esibe sesigxiliswa ku-amapuletingaphakathi komshini wokubumba umjovo.Ingxenye yangaphambili yesisekelo sesikhunta ihlanganisa ipuleti lokusekela, lapho i-mold cavity ixhunywe khona, ispruebushing, lapho izinto zizogeleza zisuka ku-nozzle, kanye nendandatho yendawo, ukuze kuhambisane nesisekelo sesikhunta ne-nozzle.Ingxenye engemuva yesisekelo sesikhunta ihlanganisa isistimu yokukhipha, lapho umgogodla wesikhunta unamathiselwe khona, kanye nepuleti lokusekela.Uma iyunithi yokubopha ihlukanisa ama-halves esikhunta, ibha yokukhipha ivula isistimu yokukhipha.Ibha yokukhipha iphusha ipuleti lokukhipa liye phambili ngaphakathi kwebhokisi le-ejector, lona eliphushela amaphini ejector engxenyeni ebunjiwe.Izikhonkwane ze-ejector ziphusha ingxenye eqinile iphume emgodini wesikhunta ovulekile.

Iziteshi zesikhunta
Ukuze ipulasitiki encibilikisiwe igeleze emigodini yesikhunta, iziteshi eziningana zihlanganiswa ekwakhiweni kwesikhunta.Okokuqala, ipulasitiki encibilikisiwe ingena esikhunjini ngokusebenzisasprue.Iziteshi ezengeziwe, ezibizwaabagijimi, baphathe ipulasitiki elincibilikisiwe kusukelaspruekuzo zonke izimbobo okufanele zigcwaliswe.Ekupheleni komgijimi ngamunye, ipulasitiki encibilikisiwe ingena emgodini ngokusebenzisa aIsangoeqondisa ukugeleza.Ipulasitiki encibilikisiwe eqina phakathi kwaleziabagijimiixhunywe engxenyeni futhi kufanele ihlukaniswe ngemuva kokuthi ingxenye ikhishwe esikhunjeni.Kodwa-ke, ngezinye izikhathi amasistimu omgijimi oshisayo asetshenziswa ashisisa iziteshi ngokuzimela, okuvumela ukuthi izinto eziqukethwe zincibilike futhi zikhishwe engxenyeni.Olunye uhlobo lwesiteshi olwakhelwe esikhunjeni amashaneli okupholisa.Le migudu ivumela amanzi ukuba ageleze ezindongeni zesikhunta, eziseduze nomgodi, futhi apholise ipulasitiki encibilikisiwe.

Isikhunta design
Ngaphezu kweabagijimifuthiamasango, kunezinye izinkinga eziningi zokuklama okufanele zicatshangelwe ekwakhiweni kwesikhunta.Okokuqala, isikhunta kufanele sivumele ipulasitiki encibilikisiwe ukuthi igeleze kalula kuyo yonke imigodi.Okubaluleke ngokufanayo ukususwa kwengxenye eqinile esikhunjeni, ngakho-ke i-engeli yokusalungiswa kufanele ifakwe ezindongeni zesikhunta.Ukwakhiwa kwesikhunta kufanele futhi kuhambisane nanoma yiziphi izici eziyinkimbinkimbi engxenyeni, njengeama-undercutsnoma imicu, ezodinga izingcezu zesikhunta ezengeziwe.Iningi lalawa madivaysi ashelela embotsheni yengxenye ngohlangothi lwesikhunta, futhi ngenxa yalokho aziwa ngokuthi ama-slides, nomaside-izenzo.Uhlobo oluvame kakhulu lwesenzo esiseceleni yi-aside-coreeyenza i-i-undercut yangaphandleukubunjwa.Amanye amadivaysi angena ekupheleni kwesikhunta eduzeisiqondiso sokuhlukana, njengeabaphakamisi bangaphakathi bangaphakathi, okungakha ii-undercut yangaphakathi.Ukubumba imicu ibe ingxenye, iidivayisi yokukhululaiyadingeka, engakwazi ukuzungeza ngaphandle kwesikhunta ngemva kokwakhiwa kwemicu.
