Indlela yokulungelelanisa isantya sokuvula isitofu sokuvula isitofu?
Uxinzelelo kunye nokulungiswa kwesantya sokuvula i-injection mold likhonkco elibaluleke kakhulu, elichaphazela ngokuthe ngqo umgangatho weemveliso, ukusebenza kakuhle kwemveliso kunye neenzuzo zoqoqosho.
Ubukhulu becala ukusuka kule miba mithathu ilandelayo ukulungelelanisa, iindlela zohlengahlengiso ezithile zezi zilandelayo:
(1) Uhlengahlengiso lwesantya sokutofa:
Isantya sokutofa sahlulwe ngesantya esiphezulu kunye nesantya esiphantsi, isantya esiphezulu sinokuphucula ukusebenza kakuhle kwemveliso, kodwa ngokukhawuleza kakhulu kuya kukhokelela kungcangcazelo lokungunda kunye nokunxiba, kunye nesiganeko esimhlophe.Isantya esisezantsi sinokuqinisekisa umgangatho wemveliso, kodwa ukucotha kakhulu kuya kwandisa iindleko zemveliso kunye nokwandisa umjikelo wemveliso.Ke ngoko, kuyafuneka ukuba ukhethe isantya sokutofa esifanelekileyo ngokwemeko yokwenyani.
Ngokubanzi, kwiindawo ezinkulu okanye eziyinkimbinkimbi zenaliti, kucetyiswa ukuba ulungelelanise ngokunyusa ngokuthe ngcembe isantya senaliti ukuze ugweme impembelelo egqithisileyo kwi-mold.
(2) Ukulungelelaniswa koxinzelelo lwenaliti:
Ubungakanani boxinzelelo lwenaliti buchaphazela ngokuthe ngqo umgangatho kunye nokumila kweendawo zokutofa.Uxinzelelo lwesitofu luncinci kakhulu, luya kukhokelela kwiindawo zokutofa ezingagcwali okanye iziphene;Uxinzelelo olugqithileyo lwenaliti luya kubangela umonakalo wokungunda okanye ukuvelisa inkunkuma eninzi kakhulu.Ke ngoko, kuyafuneka ukuba ukhethe uxinzelelo lwenaliti olufanelekileyo ngokwemeko yokwenyani.
Ngokuqhelekileyo, kwiindawo ezincinci okanye ezilula zokutofa, uxinzelelo oluphezulu lwenaliti lunokusetyenziswa;Kwiindawo zenaliti ezinkulu okanye ezinzima, uxinzelelo oluphantsi lwenaliti luyafuneka ukuze kuthintelwe impembelelo egqithisileyo kubumba.
(3) Ulawulo lobushushu:
Ubushushu yiparameter ebaluleke kakhulu kwinkqubo yokuvula isitofu sokungunda, ubushushu obuphezulu kakhulu okanye obuphantsi kakhulu buyakuchaphazela umgangatho kunye nokusebenza kweendawo zokutofa.Ngoko ke, kuyimfuneko ukukhetha ubushushu obufanelekileyo ngokwemeko yangempela.
Ngokubanzi, kwi-thermoplastics, iqondo lokushisa lifuna ukulawulwa phakathi kwe-180 ° C kunye ne-220 ° C;Kwiiplastiki ze-thermosetting, ubushushu bufuna ukulawulwa phakathi kwe-90 ° C kunye ne-150 ° C.
Ukushwankathela, uxinzelelo kunye nokulungelelaniswa kwesantya se-injection mold kufuneka kuhlalutywe kwaye kusombululwe ngokweyona meko.Ngokuqhelekileyo, ngokwandisa ngokuthe ngcembe isantya sokutofa, ukukhetha uxinzelelo olufanelekileyo lwenaliti kunye nobushushu kunye nezinye iindlela, umgangatho kunye nokusebenza kakuhle kwemveliso yeendawo zokutofa kunokuphuculwa ngokufanelekileyo, ngelixa kuncitshiswa iindleko zemveliso kunye nesantya se-scrap.
