Ukubumba umjovo kuyinqubo yokukhiqiza esetshenziswa kabanzi esetshenziselwa ukukhiqiza izingxenye zepulasitiki nemikhiqizo ehlukahlukene.Le nqubo eguquguqukayo futhi ephumelelayo yenza ukukhiqizwa okukhulu kobumo obuyinkimbinkimbi nezingxenye eziyinkimbinkimbi ngokunemba okuphezulu nokuphindaphinda.Inqubo yokubumba umjovo inezinyathelo ezimbalwa, ngasinye sibalulekile ekuqinisekiseni ukukhiqizwa kwezingxenye ezisezingeni eliphezulu.Ake sihlole inqubo yokubumba umjovo isinyathelo nesinyathelo.
Isinyathelo 1: Idizayini yesikhunta sokujova
Isinyathelo sokuqala ekubumbeni umjovo ukuklama isikhunta.Idizayini yesikhunta kufanele icabangele izici ezifana ne-engeli engasalungiswa, ukujiya kodonga, izindawo zephinikhodi yesango ne-ejector, nokubekwa kwesiteshi okupholisa ukuze kuqinisekiswe ikhwalithi ephezulu yengxenye nokwenziwa.Idizayini yesikhunta ibalulekile ekunqumeni ukunemba kobukhulu, ukuphela kwendawo, nobuqotho besakhiwo bengxenye yokugcina.Uma umklamo wesikhunta usuphothuliwe, ukhiqizwa kusetshenziswa izinqubo zokunemba zemishini.
Isinyathelo sesi-2: Ukulungiselela Okubalulekile
Izinto ezisetshenziswayo, ngokuvamile ngendlela yama-pellets noma ama-granules, zikhethwa ngokucophelela ngokusekelwe ezidingweni ezithile zomkhiqizo wokugcina.Kubalulekile ukucabangela izinto ezibonakalayo ezifana nokugeleza kwe-melt, i-viscosity, i-shrinkage namandla ukuqinisekisa ukuthi ingxenye eqediwe inezindawo ezifunwayo.Ukwengeza, ama-colorants, izithasiselo noma imicu eqinisayo ingafakwa ekuhlanganisweni kwezinto ezibonakalayo kulesi sigaba ukuze kuzuzwe ukusebenza nokubukeka okufunayo.
Isinyathelo sesi-3: I-clamping kanye nomjovo
Uma impahla kanye nokubunjwa sekulungisiwe, izigaba zokubopha nokujova zenqubo ziyaqala.Ama-halves amabili esikhunta aboshelwe ndawonye ngokuvikelekile ngaphakathi komshini wokubumba umjovo ukuze kwakheke imbobo evaliwe.I-resin yepulasitiki ibe isishisiswe ekushiseni okunembile futhi ijovwe esikhunjeni ngaphansi kwengcindezi ephezulu.Njengoba into encibilikisiwe igcwalisa umgodi, ithatha isimo sokumisa isikhunta.Isiteji somjovo sidinga ukulawula ngokucophelela imingcele yenqubo efana nesivinini somjovo, ingcindezi kanye nesikhathi sokupholisa ukuze kugwenywe amaphutha afana nama-voids, ama-sink marks noma i-warping.
Isinyathelo sesi-4: Ukupholisa nokuqinisa
Uma umgodi usugcwalisiwe, ipulasitiki encibilikisiwe ingapholisa futhi iqine ngaphakathi kwesikhunta.Ukupholisa okufanele kubalulekile ekuzuzeni ukusebenza kwengxenye edingekayo kanye nokunciphisa izikhathi zomjikelezo.Idizayini yesikhunta ihlanganisa amashaneli okupholisa asiza okokusebenza ukuqeda ukushisa ngokushesha nangokulinganayo, okuqinisekisa ikhwalithi engaguquki yengxenye kanye nokuzinza kwe-dimensional.Ukuqapha kanye nokwenza kahle inqubo yokupholisa kubalulekile ekuvimbeleni izinkinga ezifana nokuwohloka kwengxenye noma izingcindezi zangaphakathi ezingafaka engozini ubuqotho bomkhiqizo osuphelile.
Isinyathelo sesi-5: Ukukhishwa kanye Nezingxenye
Ukususwa Ngemva kokuba ipulasitiki isipholile futhi yaqina ngokugcwele, isikhunta siyavulwa futhi ingxenye esanda kwakhiwa iyakhishwa emgodini.Ukwenza kusebenze iphinikhodi ye-ejector noma indlela eyakhelwe kusikhunta iphusha ingxenye, iyikhulule endaweni yethuluzi.Inqubo yokukhipha kufanele icatshangelwe ngokucophelela ukuze kuvinjelwe ukulimala engxenyeni noma isikhunta, ikakhulukazi ngamajiyometri ayinkimbinkimbi noma izingxenye ezinezindonga ezincane.Amasistimu azenzakalelayo angasetshenziswa ukusheshisa ukukhishwa nokususwa kwezingxenye, okusiza ukuthuthukisa ukusebenza kahle kokukhiqiza kukonke.
Isinyathelo sesi-6: Nquma futhi Uqede
Uma ingxenye isikhishiwe, noma iyiphi impahla eyeqile (ebizwa ngokuthi ama-burrs) iyasikwa noma ikhishwe engxenyeni.Lokhu kungase kuhilele imisebenzi yesibili enjengokukhipha imali, ukususwa kwesango, nanoma iyiphi enye inqubo yokuqedela edingekayo ukuze kufezwe imininingwane yengxenye yokugcina.Noma yikuphi ukungapheleli okungaphezulu noma ukungahambisani kuyabhekwa, futhi kuye ngezidingo zohlelo lokusebenza, ingxenye ingathola ukucutshungulwa okwengeziwe okufana nomshini, ukushisela, noma ukuhlanganisa.
Isinyathelo sesi-7: Ukulawula Ikhwalithi Nokuhlola
Kuyo yonke inqubo yokubumba umjovo, izinyathelo zokulawula ikhwalithi ziyasetshenziswa ukuze kuqinisekiswe ukukhiqizwa kwezingxenye ezisezingeni eliphezulu.Lokhu kungase kuhlanganise ukuqapha nokulawula amapharamitha enqubo, ukuhlola izingxenye ukuze kutholwe ukukhubazeka, kanye nokwenza izivivinyo ezihlukahlukene ukuze kuhlolwe ukunemba kobukhulu, amandla, nezinye izici.
Kafushane, inqubo yokubumba umjovo iwubuchwepheshe bokukhiqiza obuyinkimbinkimbi futhi obuhlukahlukene obukwazi ukukhiqiza inqwaba yezingxenye zepulasitiki nemikhiqizo ngokunemba okukhethekile nokusebenza kahle.Zonke izinyathelo zenqubo, kusukela ekulungiseni izinto kanye nokwakhiwa kwesikhunta kuye ekupholiseni, ukukhipha kanye nokulawula ikhwalithi, kudinga ukunakwa ngokucophelela kwemininingwane nobungcweti ukuze kuzuzwe imiphumela emihle.Ngokuqonda kanye nokwenza kahle zonke izigaba zenqubo yokubumba umjovo, abakhiqizi bangakwazi ukuletha izingxenye ezisezingeni eliphezulu nezingabizi kakhulu ukuhlangabezana nezidingo zezimboni nezinhlelo zokusebenza ezihlukahlukene.
