Ukuphosa amagwebu alahlekileyo (okukwabizwa ngokuba kukubunjwa kokwenyani) kwenziwa ngeplastiki yogwebu (i-EPS, i-STMMA okanye i-EPMMA) imathiriyeli yepolymer ibe ngumngundo wokwenyani kunye nolwakhiwo olufana ncakasana kunye nobukhulu njengamacandelo aza kuveliswa kunye nokuphoswa, kwaye idip-coated. kunye ne-refractory coating (eyomeleziweyo), egudileyo kwaye inokuphefumula) kwaye yomile, ingcwatywe kwisanti eyomileyo ye-quartz kwaye ixhomekeke kwimodeli ye-vibration ye-3-dimensional. Intsimbi etyhidiweyo igalelwa kwibhokisi yesanti yokubumba phantsi koxinzelelo olubi, ukwenzela ukuba imodeli yezinto zepolymer ishushu kwaye ifakwe ngumphunga, ize ikhutshwe. Indlela entsha yokuphosa esebenzisa intsimbi engamanzi ukuze ithathe indawo yenkqubo yexesha elinye yokubumba eyenziwe emva kokupholisa kunye nokuqiniswa ukuvelisa i-castings. Ukuphosa amagwebu okulahlekileyo kunezi mpawu zilandelayo: 1. Ukusaswa kusemgangathweni olungileyo kunye neendleko eziphantsi; 2. Izinto eziphathekayo azikhawulelwanga kwaye zifanelekile kuzo zonke iisayizi; 3. Ukuchaneka okuphezulu, indawo egudileyo, ukucocwa okuncinci, kunye nomatshini omncinci; 4. Iziphene zangaphakathi ziyancipha kakhulu kwaye isakhiwo sokuphosa siphuculwe. Ixinene; 5. Inokuqonda imveliso enkulu kunye nobuninzi; 6. Ifanelekile ukukhutshwa kobuninzi bemveliso efanayo; 7. Ilungele ukusebenza ngesandla kunye nokuveliswa komgca wokudibanisa ngokuzenzekelayo kunye nokulawula ukusebenza; 8. Ubume bemveliso yomgca wemveliso ihlangabezana neemfuno zokhuseleko lokusingqongileyo iiparitha zobugcisa. ; 9. Inokuphucula kakhulu indawo yokusebenza kunye neemeko zokuvelisa umgca wemveliso yokuphosa, ukunciphisa amandla omsebenzi, kunye nokunciphisa ukusetyenziswa kwamandla.
1. I-vacuum yoxinzelelo oluphantsi olulahlekileyo lweteknoloji yokuphosa amagwebu. Idibanisa iingenelo zobuchwepheshe zokuphosa i-low-pressure cast kunye ne-vacuum elahlekileyo yokuphosa i-foam, igqiba inkqubo yokuzalisa phantsi koxinzelelo lomoya olulawulekayo, kwaye iphucula kakhulu ukukwazi ukuzaliswa kwe-alloy. Xa kuthelekiswa nokuphosa ukufa, utyalo-mali lwezixhobo luncinci, ixabiso liphantsi, kwaye i-castings inokuqiniswa ngonyango lobushushu; xa kuthelekiswa nokujulwa kwesanti, iicastings zinokuchaneka okuphezulu, uburhabaxa obusezantsi, imveliso ephezulu, kunye nokusebenza kakuhle. Ngaphantsi kwesenzo se-anti-gravity, i-sprue iba ngumjelo wokunciphisa, kwaye ukulahleka kokushisa okuthulula kuncinci. Inkqubo yokugalela i-alloy castings ilula kwaye iyasebenza, inesivuno esiphezulu kunye nesakhiwo esixineneyo. Ukushisa okufunekayo okuthululwayo kuphantsi kwaye kukulungele ukugalela kunye nokwenza ii-alloys ezahlukeneyo ezingenayo i-ferrous. .
2.Uxinzelelo olulahlekileyo lweteknoloji yokuphosa amagwebu. Idibanisa itekhnoloji yokuphosa amagwebu elahlekileyo kunye noxinzelelo lokuqina kwetekhnoloji yecrystallization. Umgaqo wayo kukugalela isinyithi esityhidiweyo kwitanki yoxinzelelo kunye nebhokisi yesanti ukwenza i-foam mold gasify kwaye iphele, emva koko utywine ngokukhawuleza itanki yoxinzelelo kwaye ungenise igesi kuxinzelelo oluthile. , ebangela ukuba isinyithi esityhidiweyo siqinise kwaye sikhanye phantsi koxinzelelo. Uphawu lwale teknoloji kukuba inokunciphisa kakhulu iziphene zokuphosa ezifana ne-shrinkage cavities, i-shrinkage porosity, kunye ne-pores kwi-castings, ukwandisa ukuxinana kwe-castings, kunye nokuphucula iimpawu ze-mechanical of castings. Ukuqiniswa phantsi koxinzelelo lwangaphandle kunokubangela ukuguqulwa kwe-microscopic ye-dendrites eqinisiweyo ekuqaleni, ukuphucula kakhulu umthamo wokutya okunyukayo kunye nokuphucula ukucutha kwangaphakathi kokuphosa. Ngelo xesha, uxinzelelo lwandisa ukunyibilika kwegesi kwi-alloy eqinile, okwenza kube lula ukukhawuleza. Amaqamza ayancipha.
