I-Metal Die Casting
Ini'sI-Die Casting?
I-Die Casting ibhekisela ohlelweni lokukhiqiza izingxenye zensimbi ezakhiwe isikhunta.Le nqubo ivumela imikhiqizo ukuthi yenziwe ngesilinganiso sokukhiqiza ngobuningi ngamanani aphezulu kanye nokuphindaphinda.Inqubo iqala ngokuphoqelela insimbi encibilikisiwe ngaphansi kwengcindezi ephezulu ibe i-die cast die.I-die ingaba nembobo eyodwa noma eminingi (izimbobo ziyisikhunta esakha isimo sengxenye).Uma insimbi isiqinile (ngokushesha njengemizuzwana engu-20) bese kuvulwe i-fasi bese isibhamu (amasango, abagijimi kanye nezingxenye zonke ezixhunyiwe) ziyasuswa futhi inqubo iqala futhi.Ngemva kokusebenza kokudubula, isibhamu sivame ukucutshungulwa ngokuqhubekayo endaweni yokunquma lapho kukhishwa khona amasango, abagijimi kanye ne-flash.Khona-ke ingxenye ingacutshungulwa ngokuqhubekayo ngokudiliza kwe-vibratory, ukudubula ukuqhuma, ukukhanda imishini, ukudweba, njll.
Izinzuzo Ze-Die Casting :
1. I-Aluminium die Casting iyinqubo evamile kakhulu yokukhiqiza izingxenye zokuphonsa ze-aluminium ezisetshenziswa ezimbonini ezihlukahlukene.Njengoba i-aluminium inokugeleza okuhle kakhulu kwempahla, imelana nokugqwala okuphezulu kanye nokuzinza kwe-dimensional ephezulu enezingxenye eziyinkimbinkimbi zomumo.
2. Khonamanjalo ingxenye ye-aluminium die casting inamandla amakhulu emishini, kulula ukuyiphonsa, futhi ibiza kancane uma iqhathaniswa nezinc noma izingxenye zokuphonsa ze-magnesium.
3. Okokugcina kodwa okungatheni, izingxenye ze-aluminium die cast zinezinto ezibonakalayo ezinhle kakhulu ezimelana nezinga lokushisa eliphezulu, okwenza ukusakaza kwe-aluminium kusetshenziswe ezimotweni, zendiza, zezokwelapha, neminye imikhiqizo yezimboni.
Izinyathelo ezinhlanu zenqubo ye-Die Casting:
Isinyathelo 1. Ukuncibilika Kwempahla
Njengoba i-aluminium inephuzu lokuncibilika eliphezulu kakhulu(660.37 °C) elingakwazi ukuncibilika ngaphakathi komshini wokulingisa ifa ngokuqondile.Kungakho sidinga ukuyincibilikisa ngaphambili ngesithando somlilo esixhunywe ngomshini wokufafaza.
Isinyathelo sesi-2. Ukukhwezwa kwethuluzi lesikhunta kanye nokuhlanganisa
Icishe ifane nokubumba umjovo, inqubo yokufaka i-die cast nayo idinga ithuluzi lokubumba lenqubo yokuphonsa.Ngakho-ke sidinga ukukhweza ithuluzi lesikhunta se-die casting emshinini wokuphonsa obandayo.
Isinyathelo 3. Umjovo noma Ukugcwalisa
Impahla encibilikisiwe idluliswa isuka esithandweni iye emshinini wokuphonsa nge-ladle enyakazayo.Kulesi sigaba, i-material izothululwa futhi iphoqelelwe emgodini wesikhunta sokuphonsa lapho okubalulekile kupholisa futhi kuqiniswe ukuze kutholwe imikhiqizo efiselekayo yokuphonsa ukufa.
Isinyathelo 4. Ukupholisa nokuqinisa
Ngemuva kokuthi ithuluzi lesikhunta se-die casting ligcwaliswe ngokuphelele ngezinto ezincibilikisiwe, kuthatha imizuzwana eyi-10 ~ 50 ukuthi liphole futhi liqiniswe (kuya ngengxenye yesakhiwo nosayizi).
Isinyathelo 5. Ukukhipha Ingxenye
Lapho isikhunta sivuleka, izingxenye eziphonsiwe zizokhishwa ngezikhonkwane ze-ejection ezivela kuthuluzi lesikhunta se-die casting.Khona-ke izingxenye ze-casted eluhlaza sezilungile.
