1. Uxinzelelo olushiyekileyo luphezulu kakhulu
Kumsebenzi wenkqubo, yeyona ndlela ilula yokunciphisa uxinzelelo olushiyekileyo ngokunciphisa uxinzelelo lwenaliti, kuba uxinzelelo lwenaliti lulingana noxinzelelo olushiyekileyo.
Ukuba iintanda kumphezulu wamalungu eplastiki zimnyama ngeenxa zonke, oko kubonisa ukuba uxinzelelo lwenaliti luphezulu kakhulu okanye isixa sokutya sincinci kakhulu. Uxinzelelo lwenaliti kufuneka luncitshiswe ngokufanelekileyo okanye umthamo wesondlo unyuswe. Xa kusenziwa phantsi kwemeko yobushushu obuphantsi bezinto eziphathekayo kunye nobushushu bomngundo, ukwenzela ukuba umgodi ugcwale, kuyimfuneko ukusebenzisa uxinzelelo oluphezulu lwenaliti, okukhokelela kuxinzelelo olukhulu olushiyekileyo kwiindawo zeplastiki.
Ukuza kuthi ga ngoku, ubushushu be-cylinder kunye nokubumba kufuneka kwandiswe ngokufanelekileyo, umahluko weqondo lobushushu phakathi kwezinto ezityhidiweyo kunye nokubumba kufuneka kuncitshiswe, ixesha lokupholisa kunye nesantya se-embryo yokubumba kufuneka ilawulwe, ukwenzela ukuba ukuqhelaniswa kwe-mold. ikhonkco yemolekyuli inexesha elide lokubuyisela.
Ukongezelela, phantsi kwesiseko sokuqinisekisa ukungondleki okwaneleyo kunye nokungenzi iinxalenye zeplastiki ziyancipha kwaye zidibanise, ixesha lokubamba uxinzelelo lingancitshiswa ngokufanelekileyo, kuba ixesha lokubamba uxinzelelo lide kakhulu kwaye kulula ukuvelisa uxinzelelo olushiyekileyo olubangela ukuqhekeka.
Kuyilo lokubumba kunye nemveliso, isango elithe ngqo kunye nokulahleka koxinzelelo oluncinci kunye noxinzelelo oluphezulu lwenaliti lunokusetyenziswa. Isango langaphambili lingatshintshwa libe yisango leenaliti ezininzi okanye isango elisecaleni, kwaye ububanzi besango bunokuncitshiswa. Xa uyila isango elisecaleni, isango le-flange elinokuthi lisuse inxalenye ephukileyo emva kokuqulunqa ingasetyenziswa.
2. Amandla angaphandle abangela uxinzelelo olushiyekileyo
Ngaphambi kokukhululwa kweengxenye zeplastiki, ukuba indawo enqamlekileyo yendlela yokukhupha incinci kakhulu okanye inani le-ejection rod ayanele, indawo yentonga ye-ejection ayifanelekanga okanye i-tilt yokufakela, ibhalansi embi, i-slope yokukhupha ukubunjwa akwanelanga, ukuchasana kwe-ejection kukhulu kakhulu, kuya kubangela uxinzelelo loxinzelelo ngenxa yamandla angaphandle, ukwenzela ukuba iindawo zeplastiki ziqhekeke kwaye ziqhekeke.
Kwiimeko eziqhelekileyo, olu hlobo lokungaphumeleli luhlala lwenzeka malunga nentonga ye-ejector. Emva kolu hlobo lokusilela, kufuneka ujonge ngononophelo kwaye ulungelelanise isixhobo sokukhupha. Intonga ye-ejector icwangciswe kwinxalenye yokuchasana kwe-demulding, efana nokuphuma, imivalo yokuqinisa, njl. Ukuba inani leentonga ze-jacking ezibekiweyo alikwazi ukwandiswa ngenxa yendawo enqabileyo yokuqhawula, indlela yokusebenzisa indawo encinci kunye neentonga ezininzi ze-jacking. inokwamkelwa.
3. Ukufakwa kwesinyithi kubangela ukuqhekeka
I-coefficient yokwandisa i-thermal ye-thermoplastic yi-9 ~ 11 amaxesha amakhulu kuneyentsimbi kunye namaxesha ama-6 amakhulu kune-aluminium. Ke ngoko, ukufakwa kwentsimbi kumacandelo eplastiki kuya kuthintela ukucutha ngokubanzi kwamalungu eplastiki, okukhokelela kuxinzelelo olukhulu, kwaye inani elikhulu loxinzelelo olushiyekileyo luya kuqokelelana malunga nokufakwa ukuze kubangele iintanda kumphezulu wamalungu eplastiki. Ngale ndlela, ukufakwa kwesinyithi kufuneka kufudunyezwe, ngakumbi xa ukuqhekeka kwendawo yeplastiki kwenzeka ekuqaleni komatshini, uninzi lwazo lubangelwa ukushisa okuphantsi kokufakwa.
Ekukhetheni izinto ezibunjwayo zokubumba, kufuneka kwakhona kusetyenziswe i-resin ubunzima bemolekyuli kangangoko kunokwenzeka, ukuba kufuneka kusetyenziswe ubunzima obuphantsi bemolekyuli yokubumba imathiriyeli ekrwada, ubukhulu beplastiki obungqonge ufakelo kufuneka lwenziwe ngqindilili, lwe-polyethylene, i-polycarbonate, i-polyamide, i-cellulose acetate. iplastiki, ubukhulu beplastiki obujikeleze i-insert kufuneka bulingane ubuncinane nesiqingatha sobubanzi bokufaka; Kwi-polystyrene, ukufakwa kwesinyithi ngokuqhelekileyo akufanelekile.
4. Ukukhetha okungafanelekanga okanye ukungacoceki kwezinto ezibonakalayo
Uvakalelo lwemathiriyeli ekrwada eyahlukeneyo kuxinzelelo olushiyekileyo lwahlukile. Ngokuqhelekileyo, i-resin engeyi-crystalline ithandwa kakhulu kukuqhekeka okubangelwa uxinzelelo olushiyekileyo kune-crystalline resin. Kwi-resin efunxayo kunye ne-resin exutywe nezinto ezihlaziyiweyo ngakumbi, ngenxa yokuba i-resin efunxayo iya kubola kwaye i-embrittleness emva kokufudumeza, uxinzelelo oluncinci lwentsalela luya kubangela ukuqhekeka okuncinci, kwaye i-resin enomxholo ophezulu wezinto ezihlaziyiweyo inokungcola okuninzi, umxholo ophezulu oguquguqukayo, ophantsi. amandla eziphathekayo, kwaye kulula ukuvelisa ukuqhekeka uxinzelelo. Ukuziqhelanisa kubonisa ukuba i-viscosity ephantsi ye-resin ekhululekile ayilula ukukrazula, ngoko ke kwinkqubo yokuvelisa, kufuneka idibaniswe nemeko ethile yokukhetha izinto ezifanelekileyo zokubumba.
Kwinkqubo yokusebenza, i-arhente yokukhululwa kwezinto ezityhidiweyo ikwangumzimba wangaphandle, njengedosi engafanelekanga iya kubangela ukuqhekeka, kufuneka uzame ukunciphisa umthamo wayo.
Ukongeza, xa umatshini wokutofa ngeplastiki kufuneka utshintshe udidi lwemathiriyeli ekrwada ngenxa yemveliso, kufuneka ucoce izinto eziseleyo kwi-hopper feeder kunye nesomisi, kwaye ucoce izinto eziseleyo kwi-cylinder.
5. Uyilo olubi lwesakhiwo samalungu eplastiki
Iimbombo ezibukhali kunye nezikhewu kwisakhiwo seengxenye zeplastiki ziyakwazi ukuvelisa uxinzelelo loxinzelelo, olukhokelela ekuqhekekeni kunye nokuqhekeka kwindawo yeplastiki. Ngoko ke, i-Angle yangaphandle kunye ne-Angle yangaphakathi yesakhiwo seplastiki kufuneka yenziwe nge-radius ephezulu ngokusemandleni. Iziphumo zovavanyo zibonisa ukuba umlinganiselo phakathi kweradius ye-arc kunye nobukhulu bodonga lwekona yi-1: 1.7. Xa uqulunqa ukwakhiwa kweengxenye zeplastiki, iinxalenye ezimele zenziwe kwiikona ezibukhali kunye neengqungquthela ezibukhali kufuneka zenziwe zibe yi-arc encinci kunye ne-radius encinci ye-0.5mm, enokwandisa ubomi bokufa.
6. Kukho ukuqhekeka kubumba
Kwinkqubo yokubumba inaliti, ngenxa yoxinzelelo lwenaliti ephindaphindiweyo yokungunda, indawo esekupheleni kombhobho eneAngle ebukhali iya kuvelisa iintanda zokudinwa, ngakumbi kufutshane nomngxuma wokupholisa kulula ngakumbi ukuvelisa iintanda. Xa isikhunta sidibene nombhobho, i-bottom of mold iyacinywa. Ukuba umngxuma wokumisa wokungunda mkhulu okanye udonga olusezantsi lubhityile, umphezulu womgodi wokungunda nawo uya kuvelisa iintanda zokudinwa.
Xa ukuqhekeka ebusweni bombhobho wokubumba kubonakaliswe kumphezulu wenxalenye yeplastiki, ukuqhekeka kwendawo yeplastiki kuhlala kubonakala ngokuqhubekayo kwimilo efanayo kwindawo efanayo. Xa ukuqhekeka okunjalo kubonakala, indawo ehambelanayo yecavity kufuneka ihlolwe ngokukhawuleza kwiimpawu ezifanayo. Ukuba ukuqhekeka kubangelwa ukubonakaliswa, ukubunjwa kufuneka kulungiswe ngomatshini.
