Isitofu sokungunda esilungiselelwe amalungu eplastiki yombane
Inkcazo
I-injection molding yindlela yokuvelisa iinxalenye ngokufaka izinto eziphathekayo kwi-mold.Iintsimbi (ezaziwa ngokuba yi-die-casting), iiglasi, ii-elastomers, ii-confections, kwaye, ngokwesiqhelo, ii-polymers ze-thermoplastic kunye ne-thermosetting zonke zinokusetyenziselwa ukubumba inaliti.Impahla yenxalenye ifakwe kwi-barrel evuthayo, ixutywe, kwaye inyanzeliswe kwi-mold cavity, apho ipholisa kwaye iqiniswe kwi-configuration ye-cavity.Emva kokuba imveliso iyilwe, ngokuqhelekileyo ngumyili wemizi-mveliso okanye injineli, ukubumba kwenziwa ngentsimbi, ngokuqhelekileyo intsimbi okanye ialuminiyam, yaye kwenziwa ngoomatshini abachanekileyo ukuze benze iimpawu zenxalenye efunekayo.Iimathiriyeli zoshicilelo ze-3D ezifana neefotopolymers ezinganyibilikiyo ngexesha lokubunjwa kwenaliti yobushushu obuphantsi be-thermoplastics zinokusetyenziselwa ezinye iinaliti zokubumba ezilula.Isitofu sokubumba sisetyenziswa ngokubanzi ukuvelisa uluhlu olubanzi lwamacandelo, ukusuka kwincinci ukuya kwenkulu kakhulu.Ukukwazi ukuvelisa iinxalenye ezineemilo zejometri kunye nobukhulu obuhlukeneyo buchongwa luhlobo lomatshini osetyenziswayo ekusebenzeni.
Imiselwe ukwenzela ukuba ungabandakanyi umoya kwi-cavity kunye neegesi kwi-plastic melting ngexesha lokujova kwi-mold.I-exhaust system ye-plastic die ye-plastic idla ngokuba yi-groove-shaped air outlet eyakhelwe kwi-die ukukhupha umoya kwi-cavity yasekuqaleni kunye neegesi eziziswe yinto etyhidiweyo. umoya kumngxuma kunye nerhasi eziswe yi inyibilika kufuneka ikhutshwe ukuya ngaphandle umngundo ngokusebenzisa exhaust port ekupheleni kokuhamba izinto, kungenjalo iya kwenza iimveliso kunye pores, uxhulumaniso olulambathayo, ukunganeliseki ukuzaliswa ngundo, kwaye nkqu. umoya oqokelelweyo uya kutshiswa ngenxa yobushushu obuphakamileyo obubangelwa kuxinzelelo.phantsi kweemeko eziqhelekileyo, i-vent inokuthi ibekwe kwi-cavity ekupheleni kokuhamba kwezinto ezityhidiweyo, okanye kwindawo yokuhlukana kwefa.
Le yokugqibela ngumsele ongenzulu onobunzulu obuyi-0.03 - 0.2 mm kunye nobubanzi obuyi-1.5 - 6 mm kwicala ledayiti. izinto ezityhidiweyo ziyakupholisa kwaye ziqiniswe kumjelo apha..Indawo yokuvula i-port yokukhupha ayifanele iqondiswe kumqhubi ukukhusela ukukhutshwa ngengozi kwezinto ezityhidiweyo. ibha kunye nomngxuma wokukhupha, kwaye phakathi kwe-ejector clump kunye netemplate kunye nengundoqo.
