Ulwakhiwo lwe-injection mold luyinkimbinkimbi, kwaye i-injection enamapleyithi amathathu idla ngokufuneka ukuze isuswe ngempumelelo, kodwa i-injection enamapleyithi amabini isengasetyenziswa kwi-injection mold engenambhobho. Ngenxa yesantya esiphezulu sokuhamba kwesango, iimolekyuli zijolise kakhulu, nto leyo enyusa uxinzelelo lwendawo kwaye ithambekele ekuqhekekeni. I-Dongguan Machike Injection Mould Factory Kwiinxalenye ezinkulu zeplastiki okanye iindawo zeplastiki eziguquguquka lula, kulula ukuzigoba nokuzola ngokusebenzisa isango elinophawu olunye. Ngeli xesha, iisango ezininzi ezinophawu zinokuvulwa ngaxeshanye ukuze zondliwe.
(3) Ukusetyenziswa kwesango lephini: Isango lephini lifanelekile kwiiplastiki ezithambileyo nezithambileyo ezibuthathaka kakhulu xa zichetywa, kwaye lifanelekile kwiimolds zokujova ezinemiqolo emininzi.
9. Isango elifihlakeleyo
Isango elifihlakeleyo, elaziwa ngokuba yisango letyhuna, livela kwisango lenqaku. Alipheleli nje ekunqobeni iintsilelo zesikhunta se-injection yesango eliyinkimbinkimbi, kodwa likwagcina neenzuzo zesango lenqaku. Isango elifihliweyo lingasetwa ecaleni kwesikhunta esishukumayo okanye kwicala lesikhunta esimiselweyo. Lingabekwa kumphezulu ongaphakathi okanye kwicala elifihliweyo lenxalenye yeplastiki, lingabekwa nakwiimbambo nakwiikholamu zenxalenye yeplastiki, kwaye lingabekwa nakwindawo yokuhlukana, kwaye ukusetyenziswa kwentonga ye-ejector yesikhunta se-injection ukuseta isango kukwayindlela elula. Isango le-volt ngokubanzi linciphile kwaye linekona ethile kwi-cavity.
(1) Iingenelo zesango elifihlakeleyo
Isango lokutya lihlala lifihliwe kumphezulu ongaphakathi okanye ecaleni kwenxalenye yeplastiki, kwaye alichaphazeli ukubonakala kwemveliso. Emva kokuba imveliso yenziwe, inxalenye yeplastiki iya kuqhekeka ngokuzenzekelayo xa ikhutshwa. Ke ngoko, kulula ukwenza ukwenziwa kwezinto ngokuzenzekelayo. Ekubeni isango elifihlakeleyo linokubekwa kwiimbambo nakwiikholamu ezingabonakaliyo kumphezulu wemveliso, iimpawu zokutshiza kunye namanqaku omoya abangelwa kukutshiza aziyi kushiywa kumphezulu wemveliso ngexesha lokubumba.
(2) Iingxaki zesango elifihlakeleyo
Ekubeni isango elifihlakeleyo lingena ngaphantsi komphezulu wokwahlukana kwaye lingene kwicala eligobileyo, kunzima ukulicubungula. Ekubeni imilo yesango iyikhowuni, kulula ukuyinqumla xa ikhutshwa, ngoko ke ububanzi kufuneka bube buncinci, kodwa kwiimveliso ezinodonga oluncinci, ayifanelekanga kuba ukulahleka koxinzelelo kukhulu kakhulu kwaye kulula ukulicubungula.
(3) Ukusetyenziswa kwesango elifihlakeleyo
Isango elifihlakeleyo lifanelekile ngokukodwa kwiindawo zeplastiki ezityalwa kwicala elinye, kwaye ngokubanzi lifanelekile kwiindawo ezineepleyiti ezimbini. Ngenxa yempembelelo enamandla kwiindawo zeplastiki ngexesha lokukhupha, kunzima ukusika iiplastiki ezinamandla kakhulu ezifana ne-PA, ngelixa kwiiplastiki ezibuthathaka ezifana ne-PS, kulula ukuphula nokuvala isango.
10. Isango leengxowa
Isango le-lug, elaziwa ngokuba yi-tap gate okanye i-adjustment gate, line-ear groove ecaleni kwe-cavity, kwaye ukunyibilika kuchaphazela ecaleni kwe-ear groove ngesango. Emva kokungena kwi-cavity emva kwesantya, kunokuthintela i-spray into xa isango elincinci lingena kwi-cavity. Lisango eliqhelekileyo le-impact. Isango le-lug lingathathwa njengotshintsho oluvela kwisango elisecaleni. Isango ngokubanzi kufuneka livulwe eludongeni oluqinileyo lwenxalenye yeplastiki. Isango lidla ngokuba sisikwere okanye uxande, i-ear groove ixande okanye i-semi-circular, kwaye i-runner iyisangqa.
(1). Iingenelo zesango leentambo
Ukunyibilika kungena kwi-lug ngesango elincinci, elinyusa ubushushu kwaye liphucule ukuhamba kwe-melt. Ekubeni isango likwi-engile ekunene kwi-lugs, xa i-melt ibetha udonga oluchaseneyo lwe-lug, indlela iyatshintsha kwaye izinga lokuhamba liyehla, okuvumela i-melt ukuba ingene kwi-cavity kakuhle nangokulinganayo. Isango likude kakhulu kwi-cavity, ngoko ke uxinzelelo olushiyekileyo kwisango aluyi kuchaphazela umgangatho weendawo zeplastiki. Xa i-melt ingena kwi-cavity, ukuhamba kuhamba kakuhle kwaye akukho msinga we-eddy oveliswayo, ngoko ke uxinzelelo lwangaphakathi kwiplastiki luncinci kakhulu.
(2) Iingxaki zesango le-lug: Ngenxa yendawo enkulu enqamlezileyo yesango, kunzima ukususa nokushiya imikhondo emikhulu, nto leyo eyonakalisa inkangeleko. I-runner inde kwaye iyinkimbinkimbi ngakumbi.
