Ukuphosa amagwebu okulahlekileyo, okwakwaziwa njengokubunjwa kokubunjwa okuqinileyo, kukudibanisa kunye nokudibanisa iimodeli zamagwebu ezinobukhulu obufanayo nokubunjwa kumaqela emodeli.Emva kokuxubha ngepeyinti ye-refractory kunye nokomisa, zingcwatywa kwisanti eyomileyo ye-quartz ye-vibration modeling, kwaye igalelwe phantsi koxinzelelo olubi ukwenza imodeli yeqela.Imodeli ye-gasification, isinyithi solwelo sithatha indawo yomzekelo, iqinisiwe kwaye ipholile ukwenza indlela entsha yokuphosa.Yonke le nkqubo ihamba ngolu hlobo lulandelayo:

Okokuqala, ukhetho lweentsimbi ze-foam:

Amaso e-polystyrene resin eyongezelelweyo (EPS) aqhele ukusetyenziselwa ukuphosa iintsimbi ezingenayo i-ferrous, intsimbi engwevu kunye nentsimbi eqhelekileyo.

2. Ukwenza imodeli: Kukho iimeko ezimbini:

1. Yenziwe ngamaso amagwebu: pre-foaming - ukunyanga - ukubumba amagwebu - ukupholisa kunye nokukhupha

①I-pre-foaming: Ngaphambi kokuba amaso e-EPS afakwe kwi-mold, kufuneka abe ne-foam ngaphambili ukuze kwandiswe ubuhlalu kwisayizi ethile.Inkqubo yangaphambili ye-foaming inquma ukuxinana, ukuzinza kwe-dimensional kunye nokuchaneka kwemodeli kwaye yenye yezixhumanisi eziphambili.Kukho iindlela ezintathu ezifanelekileyo zokufakela amaso ngaphambili: amanzi ashushu ashushu ngaphambili, i-steam prefoaming kunye ne-vacuum prefoaming.Amaso evacuum anogwebu oluphezulu, amaso awomileyo, kwaye asetyenziswa kakhulu.

②Ukuguga: Amaso e-EPS asele enogwebu abekwe kwisisele esomileyo nesingena umoya kangangexesha elithile.Ukuze ulungelelanise uxinzelelo lwangaphandle kwiiseli ze-bead, yenza amaso abe ne-elasticity kunye nekhono lokwandisa kwakhona, kwaye ususe amanzi phezu kwamaso.Ixesha lokuguga liyi-8 ukuya kwiiyure ezingama-48.

③ Ukubumba amagwebu: Gcwalisa amaso e-EPS asele enziwe amagwebu kwaye anyangekile kwisithuba sokungunda kwesinyithi, kwaye ufudumeze amaso ukuze kwandiswe kwakhona, gcwalisa izikhewu phakathi kwamaso, kwaye udibanise amaso omnye komnye ukwenza indawo egudileyo, imodeli. .Kufuneka ipholile ngaphambi kokuba i-mold ikhululwe, ukwenzela ukuba imodeli ipholile ukuya ngaphantsi kweqondo lokushisa elithambileyo, kwaye isikhunta sinokukhutshwa emva kokuba imodeli iqiniswe kwaye ibunjwe.Emva kokuba i-mold ikhutshwe, kufuneka kubekho ixesha lokuba imodeli yome kwaye i-dimensionally izinzile.

2. Yenziwe ngephepha leplastiki ye-foam: iphepha leplastiki ye-foam - ukunqanda ukusika ucingo - ukudibanisa - imodeli.Kwiimodeli ezilula, isixhobo sokusika ucingo lokuchasa singasetyenziselwa ukusika iphepha leplastiki ye-foam kwimodeli efunekayo.Kwiimodeli eziyinkimbinkimbi, okokuqala sebenzisa isixhobo sokusika ucingo lokuchasa ukwahlula imodeli kwiindawo ezininzi, kwaye emva koko unamathisele ukuze wenze imodeli epheleleyo.

3. Iimodeli zidibene zibe ngamaqela: imodeli ye-foam eyenziwe ngokwayo (okanye ethengiweyo) kunye nemodeli yokunyuka okuthululwayo idibaniswe kwaye idibaniswe kunye ukuze yenze imodeli yeklaster.Le nhlanganisela ngamanye amaxesha iqhutyelwa phambi kokugqoka, ngamanye amaxesha ekulungiseleleni ukugubungela.Kuqhutyelwa ngexesha lomzekelo webhokisi emva kokufakela.Yinkqubo eyimfuneko ekulahlekeni kwegwebu elilahlekileyo (eliqinileyo).Ngoku esetyenziswayo izixhobo zokubopha: irabha irabha, i-resin solvent kunye ne-adhesive eshushu enyibilikayo kunye nephepha leteyiphu.

4. Ukugquma imodeli: Umphezulu wemodeli ye-foam eqinileyo kufuneka ifakwe ngobunzima obuthile bepeyinti ukwenza igobolondo elingaphakathi lokubumba.Kwipeyinti ekhethekileyo yokuphosa amagwebu alahlekileyo, yongeza amanzi kwaye ugxobhoze kumxube wepeyinti ukufumana i-viscosity efanelekileyo.Ipeyinti edibeneyo ifakwe kwi-container, kwaye imodeli yeqela ifakwe ngeendlela zokudipha, ukuxubha, ukuhlamba kunye nokutshiza.Ngokubanzi, sebenzisa kabini ukwenza ukutyeba kwe-0.5 ~ 2mm.Ikhethwe ngokohlobo lwe-alloy yokuphosa, imilo yesakhiwo kunye nobukhulu.Ingubo yomile kwi-40 ~ 50 ℃.

5. Imodeli ye-Vibration: inkqubo ibandakanya la manyathelo alandelayo: ukulungiswa kwebhedi yesanti - ukubeka imodeli ye-EPS - ukuzalisa isanti - ukutywinwa kunye nokubunjwa.

① Ukulungiswa kwebhedi yesanti: Beka ibhokisi yesanti enegumbi lokutsalwa komoya kwitafile engcangcazelayo kwaye uyibambe ngokuqinileyo.

②Beka imodeli: Emva kokungcangcazela, beka iqela lemodeli ye-EPS kuyo ngokweemfuno zenkqubo, kwaye uyilungise ngesanti.

③ Ukuzaliswa kwesanti: yongeza isanti eyomileyo (iindlela ezininzi zokongeza isanti), kwaye kwangaxeshanye sebenzisa ukungcangcazela (X, Y, Z macala amathathu), ixesha ngokubanzi liyi-30 ~ 60 imizuzwana, ukuze isanti yokubumba igcwaliswe ngazo zonke iindawo. yemodeli, kwaye isanti igcwele isanti.Ubuninzi bobuninzi buyanda.

④ Ukutywinwa kunye nokumila: Umphezulu webhokisi yesanti itywinwe ngefilimu yeplastiki, ngaphakathi kwebhokisi yesanti iphonswa kwi-vacuum ethile ngempompo yokucoca, kwaye iinkozo zesanti "zibotshwe" kunye ngomahluko phakathi koxinzelelo lwe-atmospheric kunye uxinzelelo kwi-mold, ukwenzela ukuba i-mold ingawi ngexesha lokuthulula., ebizwa ngokuba yi "negative pressure setting, esetyenziswa ngokuqhelekileyo.

6. Ukugalela ukutshintshwa: Imodeli ngokuqhelekileyo ithambekele malunga ne-80 °C, kwaye ibole kwi-420 ~ 480 °C.Iimveliso zokubola zineenxalenye ezintathu: igesi, ulwelo kunye neqinile.Ubushushu bokubola kwe-thermal buhlukile, kwaye umxholo wezo zintathu uhlukile.Xa i-mold eqinile igalelwe, phantsi kobushushu besinyithi solwelo, imodeli ye-EPS idlula i-pyrolysis kunye ne-gasification, kunye nexabiso elikhulu legesi lenziwa, eliqhubeka likhutshwa kwintlabathi yokugubungela kwaye ikhutshwe ngaphandle, isenza umoya othile. uxinzelelo kwi-mold, imodeli kunye nentsimbi yentsimbi.Isinyithi sihlala sihlala kwindawo yemodeli ye-EPS kwaye siqhubela phambili phambili, kwaye inkqubo yokutshintshwa kwentsimbi engamanzi kunye nemodeli ye-EPS yenzeke.Isiphumo sokugqibela sokufuduswa kukubunjwa kokuphosa.

7. Ukupholisa kunye nokucoca: Emva kokupholisa, yeyona nto ilula ukuwisa isanti kwindawo eqinileyo.Kunokwenzeka ukuthobisa ibhokisi yesanti ukuphakamisa ukuphosa ngaphandle kwebhokisi yesanti okanye ukuphakamisa ngokuthe ngqo ukuphosa ngaphandle kwebhokisi yesanti, kwaye ukuphosa kunye nesanti eyomileyo kuyahlukana ngokwendalo.Isanti eyomileyo eyahluliweyo iyaphathwa kwaye iphinde isetyenziswe.
