Yeyiphi imiqathango yokuvulwa kwesitofu sokungunda?

Ngethuba lenkqubo yokuvula i-mold, kukho izilumkiso ezibalulekileyo ekufuneka zilandelwe ukuze kuqinisekiswe ukhuseleko kunye nokusebenza kakuhle kwemveliso ye-mold.Oku kulandelayo ngamanye amanyathelo aqhelekileyo okuvula umngundo wokutofa:

I-1, ukusebenza ngokukhuselekileyo: Ngaphambi kokuvula i-injection mold, kuyimfuneko ukuqinisekisa ukuba umqhubi ufumene uqeqesho olufanelekileyo kwaye uqhelene nesakhiwo kunye nenkqubo yokusebenza kwesikhunta.Kwangaxeshanye, umqhubi kufuneka anxibe izixhobo zokuzikhusela, ezinje ngeeglavu, iiglavu, njalo njalo, ukukhusela ukhuseleko lwabo.

I-2, ukushisa kwe-mold: ngaphambi kokuvula i-mold, kuyimfuneko ukuqinisekisa ukuba i-mold ifikelele kwiqondo lokushisa elifanelekileyo.Ukuba iqondo lokushisa lokubumba liphezulu kakhulu okanye liphantsi kakhulu, liya kuba nefuthe elibi kwinkqubo yokubumba inaliti.Ngoko ke, ngaphambi kokuvula isikhunta, iqondo lokushisa lokubumba kufuneka lihlengahlengiswe kuluhlu olufanelekileyo ngokweemfuno zezinto zokutofa kunye neeparitha zenkqubo.

I-3, indlela ye-ejector: ngaphambi kokuvula isikhunta, kuyimfuneko ukujonga ukuba i-ejector mechanism isebenza ngokuqhelekileyo.Indima ye-ejector mechanism kukukhupha imveliso eyenziwe ngenaliti kwi-mold, ukuba indlela ye-ejector ayiqhelekanga, inokubangela ukuba imveliso ibambelele okanye yonakalise.Ngoko ke, ngaphambi kokuvula isikhunta, kufuneka kuqinisekiswe ukuba umatshini we-ejector uguquguqukayo kwaye unokwethenjelwa, kwaye ukugcinwa okufunekayo kunye nokulungiswa kweempazamo kwenziwa.

I-4, isantya sokuvula umngundo: Kwinkqubo yokuvula umngundo, kufuneka ulawule isantya sokuvula ubumba.Ukuba isantya sokuvula sikhawuleza kakhulu, sinokubangela ukuguqulwa okanye umonakalo wemveliso ebunjiweyo yesitofu;Isantya sokuvula isikhunta sicotha kakhulu, siya kunciphisa ukusebenza kakuhle kwemveliso.Ke ngoko, ngaphambi kokuvula isikhunta, isantya sokuvula kufuneka sihlengahlengiswe ngokwemeko ethile ukuze kuqinisekiswe umgangatho kunye nokusebenza kakuhle kwemveliso yeemveliso zokubumba inaliti.

I-5, ukusetyenziswa kwe-lubricant: ngaphambi kokuvula i-mold, i-mold kufuneka ifakwe ngokufanelekileyo.Ukusetyenziswa kwe-lubricant kunokunciphisa ukuguga kunye nokukhuhlana, ukuphucula ubomi bokubumba kunye nokusebenza kakuhle kwemveliso.Nangona kunjalo, kufuneka kuthathelwe ingqalelo ukukhetha i-lubricant efanelekileyo kwaye ugweme ukusetyenziswa ngokugqithiseleyo, ukuze ungachaphazeli umgangatho weemveliso ezibunjiweyo zenaliti.

I-6, ukucoca i-mold: ngaphambi kokuvula isikhunta, kuyimfuneko ukuqinisekisa ukuba i-mold surface icocekile kwaye ayinathuli.Uthuli okanye ukungcola okuphezu komngundo kunokuchaphazela inkangeleko kunye nomgangatho wemveliso eyenziwe ngesitofu.Ngoko ke, ngaphambi kokuvula isikhunta, isikhunta kufuneka sicocwe ukuze kuqinisekiswe umgangatho weemveliso zokubumba inaliti.

I-7, izinto zokutofa: ngaphambi kokuvula isikhunta, kuyimfuneko ukujonga ukuba izinto zenaliti ziyahlangabezana neemfuno.Umgangatho kunye neepropathi zezinto zokubumba i-injection zichaphazela ngokuthe ngqo umphumo we-injection molding.Ngoko ke, ngaphambi kokuvula isikhunta, umgangatho kunye neenkcukacha zezinto zokubumba i-injection kufuneka zihlolwe ngononophelo ukuqinisekisa ukuba ziyahlangabezana neemfuno.

Ngamafutshane, kwinkqubo yokuvula isitofu sokubumba, kuyimfuneko ukunikela ingqalelo ekusebenzeni okukhuselekileyo, ubushushu bokubumba, indlela ye-ejector, isantya sokuvula i-mold, ukusetyenziswa kwe-lubricant, ukucocwa kwe-mold kunye ne-injection.Kuphela ngokulandela ngokungqongqo le miqathango sinokuthi siqinisekise ukhuseleko kunye nokusebenza kakuhle kwemveliso yokubumba.
