1, Incazelo yeisikhunta somjovo
Isikhunta esisetshenziselwa ukubumba ngepulasitiki sibizwa ngokuthi isikhunta sokubumba nge-injection, noma isikhunta sokubumba nge-injection ngamafuphi. Isikhunta sokubumba singabumba imikhiqizo yepulasitiki ngesimo esiyinkimbinkimbi, usayizi oqondile noma izinto ezifakiwe ngesikhathi esisodwa.
“Izingxenye eziyisikhombisa zesikhunta, inqubo yezingxenye ezintathu”. Ngokubumba ngomjovo, umshini wokubumba isikhunta kanye nomjovo unomthelela omkhulu kwikhwalithi yemikhiqizo ebunjiwe, futhi kungashiwo nokuthi isikhunta sidlala indima enkulu kunomshini wokubumba ngomjovo; Ekubumbeni ngomjovo, uma isikhunta singaqondwa ngokugcwele, kunzima ukuthola imikhiqizo emihle ebunjiwe.
2, Isakhiwo seisikhunta somjovo
Isakhiwo sesikhunta somjovo sinqunywa uhlobo lomshini wokubumba umjovo kanye nezici zesakhiwo sezingxenye zepulasitiki. Ipheya ngalinye lesikhunta lakhiwe ngesikhunta esihambayo kanye nesikhunta esiqinile. Isikhunta esihambayo sifakwa epuletini elihambayo lomshini wokubumba umjovo, kuyilapho isikhunta esiqinile sifakwa epuletini eliqinile lomshini wokubumba umjovo; Ngesikhathi sokubumba umjovo, uhlelo lokudla kanye nomgodi kwakheka ngemva kokuba isikhunta esihambayo kanye nesikhunta esiqinile sivaliwe. Lapho isikhunta sihlukaniswa, ingxenye yepulasitiki noma ingxenye kabhiya ishiywa eceleni kwesikhunta esihambayo, bese ingxenye yepulasitiki ikhishwa yindlela yokususa ebekwe esikhunta esihambayo. Ngokusho kwemisebenzi ehlukene yengxenye ngayinye esikhunta, isethi yesikhunta somjovo ingahlukaniswa ibe izingxenye ezilandelayo:
1. Izingxenye ezakhiwe
Izingxenye ezinikeza ukuma, isakhiwo kanye nosayizi ezintweni zokubumba zivame ukwakhiwa yi-core (punch), imbobo yesikhunta esigobile, i-thread core, i-insert, njll.
2. Uhlelo lokufaka isango
Yisiteshi esihola ipulasitiki encibilikisiwe isuka embozweni womjovo iye endaweni evaliweisikhuntaumgodi. Ngokuvamile yakhiwa yi-runner eyinhloko, i-splitter, i-gate kanye nomthombo wokushaja obandayo.
3. Izingxenye zomhlahlandlela
Ukuze kuqinisekiswe ukuhambisana okunembile kwedayi ehambayo kanye nedayi ehleliwe lapho ivaliwe, ingxenye yomhlahlandlela isethwe kumhlahlandlela nendawo. Yakhiwe ngensika yomhlahlandlela kanye nesiketi somhlahlandlela. Ezinye izibunjwa nazo zisethwe ngezingxenye zomhlahlandlela epuletini le-ejector ukuqinisekisa ukunyakaza okubushelelezi nokuthembekile kwendlela yokususa.
4. Indlela yokususa
Amadivayisi okususa izingxenye zepulasitiki kanye nezinhlelo zokubopha anezinhlobo eziningi zesakhiwo. Izindlela zokususa ezisetshenziswa kakhulu yi-ejector pin, i-pipe jacking, uphahla kanye ne-pneumatic ejection, ngokuvamile ezakhiwe nge-ejector rod, i-reset rod, i-slingshot, i-ejector rod fixing plate, uphahla (indandatho ephezulu) kanye ne-roof guide post/sleeve.
5. Uhlelo lokulawula izinga lokushisa lwesikhunta
Ukuze kuhlangatshezwane nezidingo zenqubo yokubumba ngomjovo kuisikhuntaizinga lokushisa, induku yokushisa yesistimu yokulawula izinga lokushisa lesikhunta iyadingeka ukuze kulungiswe izinga lokushisa lesikhunta.
6. Uhlelo lokukhipha ugesi
Ukuze kukhishwe igesi emgodini wesikhunta ngokushelela, kuvame ukubekwa indawo yokukhipha umoya endaweni yokuhlukana kwesikhunta kanye nendawo yokufakwa.
8. Ezinye izingxenye zesakhiwo
Kubhekisela ezingxenyeni ezibekwe ukuhlangabezana nezidingo zesakhiwo sesikhunta (njengepuleti eliqinile, ithempulethi elihambayo/eliqinile, ikholomu yokusekela, ipuleti lokusekela kanye nesikulufu sokuxhuma)
