Ukubumba i-silicone, eyaziwa ngokubaukugalela ngevacuum, yindlela ekhawulezayo neyoqoqosho yokuvelisa iibhetshi ezincinci zamalungu abunjiweyo enaliti.NgesiqheloSLAPubugcisaZisetyenziswa njengeprototype, ukubumba kwenziwa ngezinto ze-silicone, kunye ne-polyurethane PU imathiriyeli iphoswa ngenkqubo yokutshiza i-vacuum ukwenza i-mold composite.
Iimodyuli eziyinkimbinkimbi zinokwenza ulungelelwaniso phakathi kweziphumo zomgangatho ophezulu wemveliso, iindlela zokuvelisa uqoqosho kunye namaxesha afanelekileyo okukhokela.Oku kulandelayo zizinto ezi-3 eziphambili zenkqubo yokubumba i-silicone.
Iqondo eliphezulu lokunciphisa, ukuchaneka kwemveliso ephezulu
Iukugalela ngevacuumiindawo zinokuphinda zivelise ngokuchanekileyo ubume, iinkcukacha kunye nokuthungwa kweendawo zokuqala, kwaye zibonelele ngomgangatho ophezulu kunye nomgangatho ophezulu wokuchaneka kweendawo ezibunjiweyo zomgangatho wemoto.
Ayinaxabiso lokungunda intsimbi
Ukwenziwa ngokwezifiso kwebhetshi encinci yeendawo ezibunjiweyo zenaliti zinokugqitywa ngaphandle kokutyala imali kwimold yentsimbi ebiza imali eninzi kunye nexesha.
Ukuhanjiswa kwemveliso ngokukhawuleza
UkuthathaJS Ukongezanjengomzekelo, iimodyuli eziyinkimbinkimbi ze-200 zinokugqitywa malunga neentsuku ze-7 ukusuka kuyilo ukuya ekuhanjisweni.
Ukongeza, ngenxa yokuguquguquka okuhle kunye nokuqina kwe-silicone molds, kumalungu anezakhiwo ezintsonkothileyo, iipateni ezintle, akukho thambeka lokudilizwa, amathambeka aguquguqukayo, kunye nemijelo enzulu, zinokukhutshwa ngokuthe ngqo emva kokugalelwa, oluphawu olukhethekileyo xa kuthelekiswa. kunye nezinye iimbumba.Oku kulandelayo yinkcazo emfutshane yenkqubo yokwenza i-silicone molds.
Inyathelo 1: Yenza iPrototype
Umgangatho wenxalenye ye-silicone yokubumba kuxhomekeke kumgangatho weprototype.Singakwazi ukutshiza ukuthungwa okanye ukwenza ezinye iziphumo zokucubungula kumphezulu weSLA prototypea ukulinganisa iinkcukacha zokugqibela zemveliso.Isikhunta se-silicone siya kuvelisa ngokuchanekileyo iinkcukacha kunye nokuthungwa kweprototype, ukwenzela ukuba umphezulu we-silicone molds uya kugcina iqondo eliphezulu lokuhambelana neyokuqala.
Inyathelo 2: Yenza iSilicone Mold
Umngundo wokugalela wenziwe ngesilicone elulwelo, ekwabizwa ngokuba yi-RTV mold.I-rubber ye-Silicone izinzile ngokwekhemikhali, iyazikhulula kwaye iguquguqukayo, inciphisa ukucutheka kunye nokuphindaphinda ngokufanelekileyo iinkcukacha zenxalenye ukusuka kwiprototype ukuya kwi-mold.
Amanyathelo okuvelisa i-silicone mold zezi zilandelayo:
§Ncamathelisa iteyiphu kwindawo ethe tyaba ejikeleze iprototype ukuze kube lula ukuvula umngundo kamva, oya kuba ngumphezulu wokwahlula komngundo wokugqibela.
§Ukuxhoma iprototype kwibhokisi, ukubeka izinti zeglu kwindawo yokuseta i-sprue kunye ne-vent.
§Tofa i-silicone kwibhokisi kwaye uyitshise, emva koko uphilise kwi-oven kwi-40 ℃ kwiiyure ze-8-16, ezixhomekeke kumthamo wesikhunta.
Emva kokuba i-silicone iphilisiwe, ibhokisi kunye nentonga yeglue iyasuswa, i-prototype ikhutshwe kwi-silicone, i-cavity yenziwe, kwayei-silicone ngundoyenziwe.
Inyathelo lesi-3: Ivacuum cast
Okokuqala faka i-silicone yokubumba kwi-oven kwaye ufudumeze ukuya kwi-60-70 ℃.
§Khetha i-arhente yokukhululwa efanelekileyo kwaye uyisebenzise ngokuchanekileyo phambi kokuba uvale ukubumba, okubaluleke kakhulu ukuphepha ukunamathela kunye neziphene ezingaphezulu.
§Lungisa i-resin ye-polyurethane, uyifudumeze malunga ne-40 ° C ngaphambi kokusetyenziswa, xuba i-resin yamacandelo amabini kwi-resin echanekileyo, uze udibanise ngokupheleleyo kunye ne-degas phantsi kwe-vacuum ye-50-60 imizuzwana.
§I-resin igalelwa kumngundo kwigumbi lokufunxa, kwaye ukungunda kunyangwa kwakhona kwi-oveni.Ixesha eliqhelekileyo lokunyanga limalunga neyure enye.
§ Susa ukuphosa kwi-silicone mold emva kokunyanga.
§Phinda eli nyathelo ukuze ufumane ukungunda kwe-silicone ngakumbi.
Ukukhutshwa kwevacuuma yinkqubo yokwenziwa komngundo ethandwayo ngokukhawuleza.Xa kuthelekiswa nenye inkonzo yeprototyping, iindleko zokucwangcisa ziphantsi, umjikelo wemveliso umfutshane, kwaye iqondo lokulinganisa liphezulu, elilungele ukuveliswa kwebhetshi encinci.Ithandwa lushishino oluphezulu, i-vacuum casting inokukhawulezisa uphando kunye nenkqubela phambili yophuhliso.Ngexesha lophando kunye nexesha lophuhliso, inkcitho engeyomfuneko yemali kunye neendleko zexesha zinokuthintelwa.
