Ukukwazi ukuzalisa isinyithi esinyibilikisiweyo, ekwabizwa ngokuba yi-fluidity, yinto ebalulekileyo kwinkqubo yokuphosa. Ibhekisa kwisakhono sesinyithi esinyibilikisiweyo sokuzalisa umngxuma wokungunda ngokupheleleyo phambi kokuqina. Ukuqonda kunye nokwenza ngcono le propathi ibalulekile ekuveliseni udidi oluphezulu lweejeyometri ezintsonkothileyo kunye neziphene ezincinci.
Ingcamango esisiseko yokuZalisa ikhono
Ukuzalisa ukukwazi kwesinyithi esinyibilikisiweyo kuqinisekisa ukuba isinyithi singena njani kwaye sizalise iinkcukacha eziyinkimbinkimbi zomngundo. Iphenjelelwa zizinto ezininzi eziquka ukwakheka kwesinyithi, ubushushu, kunye nokuyilwa komngundo. Ikhono lokuzalisa kakuhle liqinisekisa ukuba ukuphosa kokugqibela kukhululekile kwiziphene ezifana ne-misruns, ukuvalwa okubandayo, kunye namacandelo angaphelelanga. Le propati ibaluleke kakhulu kwimveliso yee-castings ezinodonga oluncinci kunye namacandelo anejometri enzima.
Izinto eziPhembelela iSakhono sokuZalisa
1.Ukuqulunqwa kwesinyithi: Ukwakhiwa kweekhemikhali zentsimbi etyhidiweyo idlala indima ebalulekileyo kumanzi ayo. Izinyithi ezinamaqondo asezantsi okunyibilika zidla ngokuba nolwelo olungcono.
2.Ubushushu: Ubushushu besinyithi esinyibilikisiweyo buhambelana ngokuthe ngqo nokumanzi kwayo. Amaqondo obushushu aphezulu anciphisa i-viscosity yesinyithi, ephucula amandla ayo okugeleza kwi-mold. Nangona kunjalo, amaqondo obushushu aphezulu kakhulu anokukhokelela ekwandeni kwe-oxidation kunye nokufunxwa kwegesi, okunokubangela iziphene ekugaleleni.
3.Uyilo lokungunda: Uyilo kunye nezinto eziphathekayo zokubumba zichaphazela kakhulu amandla okugcwalisa. Umngundo onemigangatho egudileyo kunye neenkqubo ezifanelekileyo zokungena ziququzelela ukuhamba kakuhle.
4.Ireyithi yokugalela: Isantya apho isinyithi esityhidiweyo sigalelwa kwi-mold sichaphazela ukukwazi kwayo ukuzalisa umgodi. Izinga lokuthulula elilawulwayo nelihambelanayo liqinisekisa ukuba isinyithi sigcina iimpawu zayo zokushisa kunye nokuhamba, ukuthintela ukuqina kwangaphambili.
5.Izongezo: Izongezo ezithile zingangeniswa ukuphucula ubumanzi besinyithi esinyibilikisiweyo. Ngokomzekelo, i-silicon ihlala yongezwa kwii-alloys ze-aluminiyam ukunyusa ubuninzi bayo, ibenze bafaneleke ngakumbi kwii-castings ezinzima.
Amanyathelo okuphucula ukukwazi ukuzalisa
1.UKhetho lweAloyi eLungileyo: Ukukhetha ii-alloys ezineepropathi ezilungileyo zendalo ze-fluidity linyathelo lokuqala lokuphucula amandla okugcwalisa. Ngokomzekelo, ii-alloys ze-aluminiyam-silicon zikhethwa ngenxa ye-fluidity ephezulu kunye nokulula kokuphosa.
2.Ulawulo lobushushu: Ukugcina ubushushu obuphezulu bentsimbi etyhidiweyo kuyo yonke inkqubo yokuphosa ibalulekile. Ukufudumeza umngundo kunye nokulawula ubushushu obuthululwayo kunokunyusa kakhulu ulwelo. Ukusebenzisa iinkqubo zokubeka iliso lobushushu kunceda ekufumaneni iziphumo ezihambelanayo.
3.Uyilo lokungunda oluphuculweyo: Ukuyila iimolds ezinomgangatho ogudileyo, ukungena kwamanzi okwaneleyo, kunye neenkqubo zokungena ezicwangciswe kakuhle zinokwenza kube lula ukuhamba kwentsimbi.
4.Ukusetyenziswa kweInoculants kunye neFluxes: Ukongeza ii-inoculants kunokuphucula isakhiwo sengqolowa yentsimbi, ukuphucula umbane wayo. I-Fluxes ingasetyenziselwa ukususa ukungcola kunye nokunciphisa ukunyanzeliswa komhlaba, ukuphucula iimpawu zokuhamba kwesinyithi esityhidiweyo.
5.Ukukhupha isisu: Ukususa iigesi ezichithwe kwintsimbi etyhidiweyo kunokuthintela ukubunjwa kweebhubhu kunye ne-voids, ukuphucula ukukwazi ukuzaliswa ngokubanzi.
6.Iindlela zokugalela ezilawulwayo: Ukusebenzisa iinkqubo zokugalela ngokuzenzekelayo kuqinisekisa ukuhamba okuhambelanayo kunye nokulawulwayo kwesinyithi esityhidiweyo kwi-mold. Oku kunciphisa amathuba esiphithiphithi kunye nokuvalwa okubandayo, okukhokelela kwisakhono sokuzalisa ngcono.
