IsitofuIsixhobo
Isixhobo sokutofa sisixhobo esenza ukuba i-resin inyibilike ngenxa yobushushu kwaye ifakwe kwi-mold.Njengoko kuboniswe kumzobo, i-resin igxininiswe kwi-barrel ukusuka kwintloko yezinto eziphathekayo, kwaye i-melt ihanjiswa ukuya ekupheleni kombhobho ngokujikeleza kwe-screw.Kuloo nkqubo, izinto ze-resin emgqonyeni zifudunyezwa ngokufudumeza phantsi kwesenzo sokufudumala, kwaye i-resin iyanyibilika phantsi kwesenzo soxinzelelo lwe-shear ye-screw, kunye ne-resin etyhidiweyo ehambelana nemveliso etyhidiweyo, ukuhamba okuphambili. ijelo kunye nejelo lesebe liyagcinwa.Kwisiphelo sangaphambili sombhobho (obizwa ngokuba yi-metering), intshukumo eqhubekayo yokuya phambili ye-screw ifaka izinto ezibonakalayo kwi-mold cavity.Xa i-resin etyhidiweyo igeleza kwi-mold, isantya esihambayo (isantya se-injection) se-screw kufuneka silawulwe, kwaye uxinzelelo (ukubamba uxinzelelo) lusetyenziselwa ukulawula emva kokuba i-resin igcwalise i-mold cavity.Xa indawo ye-screw kunye noxinzelelo lwenaliti ifikelela kwixabiso elithile, sinokutshintsha ulawulo lwesantya kulawulo loxinzelelo.
Ukugcinwa koMngundo
1. Ishishini lokucubungula kufuneka liqale lixhobise isibini ngasinye sokubumba kunye nekhadi lokuphinda liqalise ukurekhoda kunye nokubala ukusetyenziswa kwayo, ukunakekelwa (i-lubrication, ukucoca, ukuthintela umhlwa) kunye nomonakalo ngokweenkcukacha.Ngokusekelwe kule nto, inokufumanisa ukuba zeziphi iindawo kunye namacandelo ezonakaliswe kunye neqondo lokugqoka.Ukubonelela ngolwazi malunga nokufumanisa kunye nokusombulula iingxaki, kunye neeparitha zenkqubo yokubumba i-mold, kunye nezinto ezisetyenziswa kwimveliso ukunciphisa ixesha lokuqhuba isilingo sokubumba kunye nokuphucula ukusebenza kakuhle kwemveliso.
2. Inkampani yokucubungula kufuneka ivavanye iimpawu ezahlukeneyo zokubumba phantsi kokusebenza okuqhelekileyo komatshini wokubumba umjovo kunye nokubumba, kwaye ulinganise ubungakanani benxalenye yokugqibela yeplastiki ebunjiweyo.Ngolu lwazi, imeko yangoku yesikhunta inokumiselwa, kwaye i-cavity kunye nengundoqo inokufumaneka., Inkqubo yokupholisa kunye nendawo yokuhlukana, njl., ngokweenkcukacha ezinikezelwe ngamacandelo eplastiki, imeko yomonakalo wesikhunta kunye namanyathelo okulungisa inokugwetywa.
3. Gxininisa ekulandeleni nasekuvavanyeni iindawo ezininzi ezibalulekileyo zesikhunta: i-ejector kunye nezixhobo zesikhokelo zisetyenziselwa ukuqinisekisa ukuvulwa nokuvala ukunyakaza kwe-mold kunye nokukhutshwa kwenxalenye yeplastiki.Ukuba nayiphi na inxalenye yokungunda ibambekile ngenxa yomonakalo, iya kubangela ukuba imveliso imise.Ngalo lonke ixesha gcina ithumba lokungunda kunye nesithuba sesikhokelo sithanjisiwe (esona sithambiso sifanelekileyo kufuneka sikhethwe), kwaye ujonge rhoqo ukuba ithontsi, isithuba sesikhokelo, njl.Nje ukuba ifunyenwe, yibuyisele ngexesha;emva kokugqiba umjikelo wemveliso, umngundo kufuneka ube Umphezulu osebenzayo, ushukumayo kunye neendawo ezikhokelayo ziqatywe nge-oyile yobuchwephesha echasene nomhlwa, kwaye ingqalelo ekhethekileyo kufuneka ihlawulwe ekukhuselweni kwamandla e-elastic kwiindawo ezithwele igiya, ukungunda kwe-rack. kunye nokungunda kwentwasahlobo ukuqinisekisa ukuba bahlala bekwimeko engcono yokusebenza;Ngokuhamba kwexesha, umjelo wokupholisa uthambekele ekufakeni isikali, umhlwa, intlenga, kunye nealgae, nto leyo inciphisa icandelo lomnqamlezo wejelo lokupholisa kwaye icuthe ijelo lokupholisa, elinciphisa kakhulu izinga lokutshintsha kobushushu phakathi kwesipholisi kunye nokungunda, kwaye kwandisa ixabiso lemveliso yeshishini.
Ngoko ke, ishaneli yokuhambisa Ukucocwa kwesikhunta somqhubi oshushu kufuneka sinikwe ingqalelo;kwisikhunta somqhubi oshushu, ukugcinwa kwenkqubo yokufudumala kunye nokulawula kunceda ukukhusela ukwenzeka kokusilela kwemveliso, ngoko kubaluleke kakhulu.Ngoko ke, emva komjikelezo ngamnye wokuvelisa, izifudumezi zebhanti, izifudumezi zeentonga, iiprobes zokufudumala kunye ne-thermocouples kwi-mold kufuneka zilinganiswe nge-ohmmeter.Ukuba zonakaliswe, kufuneka zitshintshwe ngexesha kwaye zihlolwe ngembali yokubumba.Thelekisa kwaye ugcine iingxelo ukuze iingxaki zifunyanwe ngexesha kwaye kuthathwe amanyathelo okuthintela.
4. Nika ingqalelo ukugcinwa komphezulu we-mold.Ichaphazela ngokuthe ngqo umgangatho womgangatho wemveliso.Kugxilwe ekuthinteleni umhlwa.Ke ngoko, kubaluleke kakhulu ukukhetha ioyile efanelekileyo, ekumgangatho ophezulu, kunye neyobuchwephesha yokuchasana nomhlwa.Emva kokuba umngundo ugqibezele umsebenzi wemveliso, iindlela ezahlukeneyo kufuneka zisetyenziswe ukususa ngononophelo ukubumba kwenaliti eshiyekileyo ngokwenaliti eyahlukileyo yokubumba.Iintonga zobhedu, iingcingo zobhedu kunye neearhente zokucoca ukungunda ezinobuchwephesha zingasetyenziselwa ukususa ukubunjwa kwenaliti eshiyekileyo kunye nezinye iidiphozithi kumngundo, emva koko wome umoya.Akuvumelekanga ukucoca izinto ezinzima ezifana neengcingo zentsimbi kunye nemivalo yentsimbi ukuphepha ukukrazula phezulu.Ukuba kukho amabala erusa abangelwa kukubumba inaliti edlekayo, sebenzisa isixhobo sokusila ukucola nokupholisha, kwaye utshize i-oyile yobuchwephesha yokunqanda umhlwa, uze ugcine ukungunda kwindawo eyomileyo, epholileyo, nengenathuli.
