1. Incazelo yeumjovo isikhunta
Isikhunta esisetshenziselwa ukubumba umjovo wepulasitiki sibizwa ngesikhunta sokubumba umjovo, noma isikhunta somjovo ngamafuphi.Isikhunta somjovo singabumba imikhiqizo yepulasitiki enomumo oyinkimbinkimbi, usayizi oqondile noma ukufakwa ngesikhathi esisodwa.
"Izingxenye eziyisikhombisa isikhunta, izingxenye ezintathu inqubo".Ngokubunjwa komjovo, umshini wokubumba kanye nomjovo wokubumba unomthelela omkhulu kwikhwalithi yemikhiqizo ebunjiwe, futhi kungashiwo ukuthi isikhunta sidlala indima enkulu kunomshini wokubumba umjovo;Ekubunjweni komjovo, uma isikhunta singaqondi ngokugcwele, kunzima ukuthola imikhiqizo emihle ebunjiwe.
2. Isakhiwo seumjovo isikhunta
Isakhiwo sesikhunta somjovo sinqunywa uhlobo lomshini wokubumba umjovo kanye nezici zesakhiwo sezingxenye zepulasitiki.Ipheya ngalinye lesikhunta lakhiwe isikhunta esinyakazayo kanye nesikhunta esingaguquki.Isikhunta esihambayo sifakwe epuletini elihambayo lomshini wokubumba umjovo, kuyilapho isikhunta esimisiwe sifakwe epuleti elimisiwe lomshini wokubumba umjovo;Ngesikhathi sokubunjwa komjovo, uhlelo lokudla kanye ne-cavity kwakheka emva kokubunjwa okunyakazayo kanye nesikhunta esimisiwe sivaliwe.Lapho isikhunta sihlukaniswa, ingxenye yepulasitiki noma ingxenye kabhiya ishiywe eceleni kwesikhunta esinyakazayo, bese ingxenye yepulasitiki ikhishwa umshini wokudiliza obekwe ekubunjweni okuhambayo.Ngokusho kwemisebenzi ehlukene yengxenye ngayinye ekubunjweni, isethi yesikhunta sokujova ingahlukaniswa ngezingxenye ezilandelayo:
1. Izingxenye ezakhiwe
Izingxenye ezinikeza ukwakheka, ukwakheka kanye nosayizi wezinto zokubumba zivame ukwakhiwa core (punch), umgodi we-concave mold, intambo core, ukufaka, njll.
2. Uhlelo lokungena
Yisiteshi esiholela ipulasitiki encibilikisiwe isuka kubhobho lomjovo iye endaweni evaliweisikhuntaumgodi.Ngokuvamile kuhlanganiswe umgijimi oyinhloko, isihlukanisi, isango kanye nokushaja okubandayo kahle.
3. Izingxenye zomhlahlandlela
Ukuze kuqinisekiswe ukuqondana okunembile kwefa elinyakazayo kanye nefa elimisiwe lapho kuvalwa, ingxenye yomhlahlandlela isethelwe ukuqondisa kanye nokuma.Yakhiwe ngensika yomhlahlandlela kanye nomkhono womhlahlandlela.Okunye ukubumba kuphinde kusethwe ngezingxenye zomhlahlandlela epuleti le-ejector ukuze kuqinisekiswe ukunyakaza okubushelelezi nokuthembekile kwendlela yokudiliza.
4. Indlela yokubhidliza
Amadivayisi okubhidliza izingxenye zepulasitiki kanye nezinhlelo zokugenca anamafomu amaningi esakhiwo.Izindlela ezivame ukusetshenziswa kakhulu zokudiliza iphini lokukhipa, ukugenca kwepayipi, uphahla kanye nokukhipha umoya, ngokuvamile akhiwa induku yokukhipha umoya, induku yokusetha kabusha, isihlilingi, ipuleti lokulungisa induku ye-ejector, uphahla (indandatho ephezulu) kanye nesigxobo/umkhono wophahla.
5. Uhlelo lokulawula izinga lokushisa kwesikhunta
Ukuze kuhlangatshezwane nezidingo zenqubo yokubumba umjovo ku-isikhuntaizinga lokushisa, isikhunta esilawula ukushisa kwesistimu yokushisa induku iyadingeka ukulungisa izinga lokushisa lesikhunta.
6. Isistimu yokukhipha umoya
Ukuze kukhishwe igesi endaweni yokubunjwa kahle, i-exhaust slot ivame ukusetha endaweni yokuhlukanisa isikhunta kanye nendawo efanelekile yokufaka.
8. Ezinye izingxenye zesakhiwo
Kubhekiselwa ezingxenyeni ezisethwe ukuze zihlangabezane nezidingo zesakhiwo sesikhunta (njengepuleti elingashintshi, isifanekiso esigudlukayo/esigxilile, ikholomu yokusekela, ipuleti lokusekela nesikulufu sokuxhuma)
