Shell Mold Casting

Shell Mold Casting Foundry

Ukubunjwa kweqokobhe kukwabizwa ngokuba yinkqubo yokuphosa isanti yentlabathi eqatywe ngaphambili, ukubunjwa kweqokobhe elishushu okanye inkqubo yokuphosa engundoqo. Izinto eziphambili zokubumba yintlabathi ye-phenolic resin efakwe ngaphambili, ebiza kakhulu kunokubaisanti eluhlazakunye nesanti ye-furan resin. Ngaphezu koko, le santi ayinakuphinda isetyenziswe.

Amacandelo okubumba iqokobhe aneendleko eziphezulu kancinci kuneukugalela isanti. Nangona kunjalo, iiqokobhe lokubumba iindawo zokugalelazineenzuzo ezininzi ezifana nokunyamezelana okuqinileyo, umgangatho olungileyo womphezulu kunye neziphene ezincinci zokuphosa.

Ngaphambi kokwenza i-mold kunye ne-core, isanti edibeneyo ihlanganiswe nefilimu eqinile ye-resin phezu kweengqungquthela zesanti. Isanti egqunyiweyo ikwabizwa ngokuba yisanti yeqokobhe (core) sand. Inkqubo yethekhnoloji kukuxuba ngomatshini umthi wephenolic owenziwe ngumgubo kunye nesanti ekrwada kwaye uqine xa ushushu. Iphuhliswe yaba yintlabathi egqunyiweyo ngokusebenzisa i-thermoplastic phenolic resin kunye ne-latent curing agent (efana ne-urotropine) kunye ne-lubricant (efana ne-calcium stearate) ngenkqubo ethile yokwaleka.

Xa isanti egqunyiweyo ishushu, i-resin egqunywe phezu kwendawo yentlabathi iyanyibilika. Ngaphantsi kwesenzo seqela le-methylene elichithwa yi-Maltropine, i-resin etyhidiweyo iguquka ngokukhawuleza ukusuka kwisakhiwo somgca ukuya kwisakhiwo somzimba esingenasiphelo ukwenzela ukuba isanti edibeneyo iqiniswe kwaye yenziwe. Ukongeza kwindlela eyomileyo ye-granular yesanti egqunyiweyo, kukho isanti emanzi kunye ne-viscous egqunywe.

Emva kokuxuba isanti yoqobo (okanye isanti ebuyisiweyo), intlaka engamanzi kunye ne-catalyst engamanzi ngokulinganayo, kwaye ugcwalise kwibhokisi engundoqo (okanye ibhokisi yesanti), kwaye emva koko uyiqinise ukuze iqine ibe ngumbumba okanye i-mold kwibhokisi engundoqo (okanye ibhokisi yesanti). ) kwiqondo lokushisa lokushisa, i-mold casting okanye i-casting core yenziwa, ebizwa ngokuba yi-self-hardening-cold-core modeling box (core), okanye indlela yokuziqinisa (core). Indlela yokuziqinisa inokwahlulwa ibe yi-acid-catalyzed furan resin kunye ne-phenolic resin sand self-harding method, i-urethane resin sand self-harding method kunye ne-phenolic monoester self-harding method.

Iqokobhe Mold Ukuphosa Amanyathelo

✔ Ukwenza iipateni zesinyithi.Isanti ye-resin efakwe ngaphambili kufuneka ifudunyezwe kwiipateni, ngoko ke iipateni zetsimbi zizixhobo eziyimfuneko ukwenza i-shell molding castings.
✔ Ukwenza i-Sand Mold eqatywe kwangaphambili.Emva kokufaka iipateni zetsimbi kumatshini wokubumba, isanti ye-resin efakwe ngaphambili iya kudutshulwa kwiipatheni, kwaye emva kokufudumeza, i-resin yokugqoka iya kunyibilika, emva koko iimbumba zesanti zibe yigobolondo yesanti eqinile kunye neentsimbi.
✔ Ukunyibilikisa iCast Metal.Ukusebenzisa i-furnaces induction, izinto ziya kunyibilika zibe yi-liquid, emva koko ukubunjwa kweekhemikhali zesinyithi se-liquid kufuneka kuhlalutywe ukuze kuhambelane namanani afunekayo kunye neepesenti.
✔ Ukugalela isinyithi.Xa isinyithi esinyibilikisiweyo sihlangabezana neemfuno, ngoko ziya kugalelwa kwi-shell shell molds. Ngokusekwe kubalinganiswa abahlukeneyo boyilo lokubunjwa, ukubumba iqokobhe kuya kungcwatywa kwisanti eluhlaza okanye kuhlanganiswe ngamaleko.
✔ Ukudutyulwa kokuqhunyiswa, ukuSila kunye nokuCoca.Emva kokupholisa kunye nokuqiniswa kwee-castings, ukukhuphuka, amasango okanye isinyithi esongezelelweyo kufuneka sinqunywe kwaye sisuswe. Emva koko iintsimbi ziyakucocwa ngezixhobo zokukrola esantini okanye ngoomatshini abadubulayo. Emva kokugaya intloko yesango kunye nemigca yokuqhawula, iinxalenye ezigqityiweyo zokuphosa ziza kuza, zilindele iinkqubo ezingaphezulu xa zifuneka.

Izinto eziluncedo kwi-Shell Mold Casting

1) Inokusebenza okufanelekileyo kwamandla. Inokuhlangabezana neemfuno zesanti engundoqo yeqokobhe eliphezulu, isanti yebhokisi eshushu ephakathi nendawo, kunye nesanti yealloy engenawo amandla asezantsi.
I-2) I-fluidity egqwesileyo, ukubunjwa kakuhle kwengundoqo yesanti kunye nolwandlalo olucacileyo, olunokuvelisa i-sand cores enzima kakhulu, njenge-sand cores yebhantshi yamanzi njengeentloko ze-cylinder kunye nemizimba yomatshini.
3) Umgangatho ophezulu wesiseko sesanti ulungile, uhlangene kwaye awukhululekanga. Nokuba kuthe kwafakwa i-coat encinci okanye akukho nto, umgangatho ongcono we-castings unokufumaneka. Ukuchaneka kwe-dimensional of castings kunokufikelela kwibakala ukusuka kwi-CT 7 - CT 8, kunye noburhabaxa bomhlaba uRa unokufikelela kwi-6.3 - 12.5 μm.
4) I-collapsibility efanelekileyo, ehambelana nokuphosa ukucoca kunye nokuphucula ukusebenza kwemveliso
5) Undoqo wesanti akulula ukufunxa umswakama, kwaye amandla okugcinwa kwexesha elide akulula ukunciphisa, okulungele ukugcina, ukuthutha kunye nokusetyenziswa.
