Kuyini ukubumba umjovo futhi kusebenza kanjani

Ukubunjwa kwe-injection kuyinqubo yokwakha kusetshenziswa isikhunta. Izinto ezifana nama-synthetic resins (amapulasitiki) ziyashiswa futhi zincibilike, bese zithunyelwa esikhunjeni, lapho zipholile khona ukuze zenze umumo oklanyelwe. Ngenxa yokufana nenqubo yokujova uketshezi ngesirinji, le nqubo ibizwa ngokuthi i-injection molding. Ukugeleza kwenqubo kanje: izinto ziyancibilika futhi zithululelwe esikhunjeni, lapho ziqina khona, bese zisuswa futhi ziqedwe.

Ngokubumba komjovo, izingxenye zobumo obuhlukahlukene, kuhlanganise nalezo ezinobunjwa obuyinkimbinkimbi, zingakhiqizwa ngokuqhubekayo futhi ngokushesha, ngamavolumu amakhulu. Ngakho-ke, ukubumba komjovo kusetshenziselwa ukwenza izinto ezingavuthiwe nemikhiqizo ezinhlobonhlobo zezimboni.

Imishini yokubumba injekishini

Imishini yokubumba imijovo iza ngezinhlobo ezahlukene, njengemishini ye-servo motor driven motorized, hydraulic motor driven hydraulic machines, kanye nemishini ye-hybrid eqhutshwa inhlanganisela ye-servomotor kanye ne-hydraulic motor. Isakhiwo somshini wokubumba umjovo singafinyezwa cishe njengeyunithi yomjovo ethumela izinto ezincibilikisiwe esikhunjeni, kanye neyunithi yokubopha esebenza isikhunta.

Eminyakeni yamuva, ukusetshenziswa kwe-CNC kuye kwamukelwa ngokuya emishini yokubumba umjovo, okuholela ekudumeni kwamamodeli avumela umjovo wesivinini esikhulu ngaphansi kokulawulwa okuhleliwe. Ngakolunye uhlangothi, kusetshenziswa imishini eminingana ekhethekile, njengamamodeli akha amapuleti omhlahlandlela wokukhanya wamamonitha e-LCD.

Inqubo yokubumba umjovo

Ukubunjwa kwe-injection iqala ngama-resin pellets (ama-granules) athululelwa ku-hopper, indawo yokungena yezinto. Ama-pellets abe eseshiswa futhi ancibilike ngaphakathi kwesilinda ukulungiselela umjovo. Izinto ezisetshenziswayo zibe seziphoqelelwa ngombhobho weyunithi yomjovo, ngaphambi kokulethwa ngomgudu okwisikhunta esibizwa ngokuthi i-sprue, bese kuba ngama-branched runners ungene emgodini wokukhunta. Lapho impahla isipholile futhi iqina, isikhunta siyavuleka futhi ingxenye ebunjiwe ikhishwe kuso. Ukuze uqedele ingxenye ebunjiwe, i-sprue kanye nomgijimi banqunywe kusukela engxenyeni.

Kubalulekile ukuthi izinto ezincibilikisiwe zisatshalaliswe ngokulinganayo kulo lonke isikhunta, njengoba kuvame ukuba nesikhala esingaphezu kwesisodwa ngaphakathi kwesikhunta, okuvumela ukukhiqizwa kwengxenye engaphezu kweyodwa ngesikhathi. Ngakho-ke, ukuma kwesikhunta kufanele kuklanywe ngendlela eqinisekisa lokhu, isibonelo, ukuba nabagijimi bezilinganiso ezifanayo.

Nakuba ukubumba komjovo kulungele ukukhiqizwa ngobuningi, kubalulekile ukuqonda kahle izimo ezihlukahlukene ezidingekayo ukuze kukhiqizwe imikhiqizo enembayo ephezulu, okuhlanganisa ukukhethwa kwempahla ye-resin, ukunemba kokucubungula isikhunta kanye nezinga lokushisa lomjovo wokuhlanganisa kanye nesivinini.

Ukusetshenziswa kwale mishini kugcina kwenyusa amandla anoma iyiphi inkampani. Umjovo wepulasitiki uvumela ngokufingqiwe ukukhiqizwa ngendlela elula, esheshayo nekhwalithi yezicucu eziningi, ukunciphisa inani lamaphutha ngesilinganiso esikhulu. Uma sisebenza ngomjovo, ukulungiswa kahle kwale mishini yinto ehamba phambili kithi.
