Inkqubo yokubumba inaliti isebenzisa iimolds, ezenziwe ngentsimbi okanye i-aluminium, njengesixhobo esiqhelekileyo.Umngundo unamalungu amaninzi, kodwa unokwahlulwa ube ziziqingatha ezibini.Isiqingatha ngasinye sincanyathiselwe ngaphakathi kumatshini wokubumba inaliti kwaye isiqingatha sangemva sivumelekile ukuba sisityibilike ukuze isikhunta sivulwe kwaye sivalwe ecaleni komngundo.umgca wokwahlula.Amacandelo amabini aphambili obumba ngundoqo wokungunda kunye nomgodi wokungunda.Xa umngundo uvaliwe, isithuba phakathi kondoqo wokungunda kunye nomgodi wokungunda senza indawo yomngxuma, eya kuzaliswa ngeplastiki etyhidiweyo ukuze idale indawo efunwayo.Ngamanye amaxesha kusetyenziswa ukubumba okunemingxuma emininzi, apho iziqingatha ezibini zokungunda zenza iinxalenye ezininzi ezifanayo.
Isiseko sokungunda
I-mold core kunye ne-mold cavity nganye ifakwe kwisiseko sokubumba, esiye sigxininiswe kwiiipleyitingaphakathi kumatshini wokubumba inaliti.Isiqingatha sangaphambili sesiseko sokubumba sibandakanya ipleyiti yokuxhasa, apho i-mold cavity ifakwe khona, ispruebushing, apho izinto ziya kuhamba ukusuka kwi-nozzle, kunye nendandatho yendawo, ukwenzela ukulungelelanisa isiseko sokubumba kunye ne-nozzle.Isiqingatha sangemva sesiseko sokubumba sibandakanya inkqubo yokukhupha, apho i-mold core iqhotyoshelweyo, kunye neplate yokuxhasa.Xa iyunithi yokudibanisa ihlula iihafu zokubumba, i-ejector bar ivuselela inkqubo yokukhupha.Ibar ye-ejector ityhala ipleyiti ye-ejector phambili ngaphakathi kwebhokisi ye-ejector, leyo yona ityhala izikhonkwane ze-ejector kwindawo ebunjiweyo.Izikhonkwane ze-ejector zityhala indawo eyomeleleyo ngaphandle komngxuma wokungunda ovulekileyo.

Imijelo yokungunda
Ukuze iplastiki etyhidiweyo ingene kwimingxuma yokubumba, iziteshi ezininzi zihlanganiswe kuyilo lokubumba.Okokuqala, iplastiki etyhidiweyo ingena kwi-mold ngokusebenzisasprue.Iitshaneli ezongezelelweyo, ezibizwaiimbaleki, baphathe iplastiki etyhidiweyo ukusuka kwispruekuyo yonke imingxuma ekufuneka igcwaliswe.Ekupheleni kwembaleki nganye, iplastiki etyhidiweyo ingena kumngxuma ngokusebenzisa aIsangoelawula ukuhamba.Iplastiki etyhidiweyo eqina ngaphakathi kweziiimbalekiifakwe kwinxalenye kwaye kufuneka ihlulwe emva kokuba inxalenye ikhutshwe kwi-mold.Nangona kunjalo, ngamanye amaxesha iinkqubo zembaleki ezishushu zisetyenziselwa ukufudumeza ngokuzimeleyo iziteshi, ukuvumela ukuba izinto eziqulethweyo zinyibilike kwaye zikhutshwe kwinxalenye.Olunye uhlobo lomjelo olwakhelwe kwimold yimigudu yokupholisa.Le mijelo ivumela amanzi ukuba ahambe kwiindonga zokungunda, ezimelene nomngxuma, aze apholise iplastiki etyhidiweyo.

Uyilo lokungunda
Ukwengeza kwiiimbalekikwayeamasango, kukho eminye imiba yoyilo ekufuneka iqwalaselwe kuyilo lokubumba.Okokuqala, umngundo kufuneka uvumele iplastiki etyhidiweyo ukuba ihambe ngokulula kuyo yonke imingxuma.Okubaluleke ngokulinganayo ukususwa kwenxalenye eqinisiweyo kwi-mold, ngoko i-angle eyidrafti kufuneka ifakwe kwiindonga zokubumba.Uyilo lokungunda kufuneka lufake naziphi na iimpawu ezintsonkothileyo kwicandelo, njengeiindlela ezisezantsiokanye imisonto, nto leyo eza kufuna amaqhekeza umngundo ezongezelelweyo.Uninzi lwezi zixhobo zityibilika kwicango lokungunda, kwaye ke zaziwa njengezilayidi, okanye.izenzo ezisecaleni.Olona hlobo luxhaphakileyo lwesenzo secala yi aicala-coreeyenza ukuba ii-undercut yangaphandleukubunjwa.Ezinye izixhobo zingena ekupheleni komngundo ecaleni kweindlela yokwahlukana, njengeiziphakamisi ezingundoqo zangaphakathi, enokwenza ii-undercut yangaphakathi.Ukubumba imisonto kwindawo, iisixhobo sokukhululaiyadingeka, enokuthi ijikeleze ngaphandle kokubumba emva kokuba imicu yenziwe.
