DIY liquid mold rudzi rutsva rwesilicone molds, mhando dzakasiyana dzemhuka, maruva, michero nemhizha, nezvimwewo, chimwe nechimwe chinogona kuitwa, ita zvese zvinoyevedza, DIY liquid mold ndiyo huru zvinhu is liquid silicone.
Liquid silicone ndeye isiri-chepfu, inodzivirira kupisa, inodzoreredzwa zvakanyanya kuchinjika thermosetting transparent material yeorganic silicone, maitiro ayo e sulfuric anonyanya kuratidzwa mune yakaderera viscosity, kukurumidza kurapa, shear kutetepa uye yakakwirira coefficient yekuwedzera kupisa.Zviviri-zvikamu zvakakwirira zvakajeka, simba rakakwirira, yakakwira kubvarura kuramba liquid silicone rabha yakakodzera jekiseni kuumba maitiro.
Liquid silicone rubber inosanganisira liquid silicone rabha, 0 degree liquid silicone rubber, zero degree liquid silicone rubber, 5 degree liquid silicone rubber, 10 degree liquid silicone rubber, 15 degree liquid silicone rubber, 20 degree liquid silicone rubber, 25 degree liquid silicone rubber, 30 degree liquid silicone rubber, 40 degree liquid silicone rubber, 50 degree liquid silicone rubber, 60 degree liquid silicone rubber, 80 degree liquid silicone rabha, ayo akasiyana kuoma kwemvura silicone rabha pamusika silicone rabha.Kana isu tichigadzira DIY mvura mold, tinogona kusarudza kwakasiyana kuomarara kwerabha yemvura zvinoenderana nezvatinoda kugadzira mold.
Iyo yekugadzira maitiro e DIY liquid molds:
Dhizaina DIY zvigadzirwa
Dhirowa 3D prototypes
Simbisoprototypes
Prototype mifananidzo
Mienzaniso yekubuda
Kugadzirwa kwakawanda
Panowanzova nezvinetso zvinosangana pakugadzira mvura silicone molds, saka ndezvipi zvimwe zvezvinhu izvi zvatinofanira kuziva?Kazhinji, chimiro chemvura silicone molds yakafanana neye thermoplastics, asi pane zvakawanda zvakakosha zvakasiyana.Iyo viscosity yesilicone yemvura inowanzo kuderera, saka nguva yekuzadza ipfupi, kunyangwe kune yakaderera jekiseni kumanikidza.Kuti udzivise kuteya mhepo, mudziyo wakanaka wekufema unofanirwa kunge uripo muforoma.
Pamusoro pezvo, masilicones emvura haadonhe muforoma sezvinoita thermoplastic compounds.Ivo vanowanzo wedzera kupisa uye havanyanye zvishoma sezvaitarisirwa kuitira kuti chigadzirwa chavo chisarambe chiri padivi re convex ye mold sezvanga zvichitarisirwa.Inonamira mukati menzvimbo yakakura yenzvimbo ye mold cavity.
Chengetedzo yekugadzira liquid silicone molds.
1. Kuderera
Kunyange zvazvo silica yemvura isinganyanyi kunyura muforoma, inozoderera mushure mekugadzirisa uye kutonhora ne 2.5 kusvika ku 3. Iyo chaiyo dhigirii ye shrinkage inotsamira pane imwe nhanho pakuumbwa kwekomboni.Nekudaro, kubva pakuona mold, shrinkage inogona kukanganiswa nezvinhu zvakati wandei, zvinosanganisira tembiricha yeforoma, tembiricha iyo iyo komputa inoderedzwa, kudzvanywa mukati memhango, uye kunotevera kudzvanywa.
Nzvimbo yejekiseni poindi inofanirwawo kutariswa, sezvo shrinkage munzira yekuyerera kwekomboni kazhinji yakakura kupfuura shrinkage munzira yakatarisana nekomboni.Chimiro chehukuru hwechigadzirwa chinewo mhedzisiro pakudzikira kwayo, ine zvigadzirwa zvakakora zvinowanzo kuderera zvishoma.
2. Mutsara wekuparadzanisa
Nhanho yekutanga mukugadzirwa kwesilicone rubber jekiseni mold ndeyekuona nzvimbo yemutsara wekuparadzanisa.Venting inonyanya kuwanikwa kuburikidza ne groove iri pamutsara wekuparadzanisa, iyo inofanira kunge iri munzvimbo iyo jekiseni rabha rinozopedzisira rasvika, nokudaro kudzivisa kuumbwa kwemhepo inoputika uye kuderedza kurasikirwa kwesimba mumubatanidzwa wakabatanidzwa.
Nekuda kweiyo yakaderera viscosity yeiyo yemvura silicone, mutsara wekupatsanura unofanirwa kuve wakarurama kudzivirira kuparara.Kunyange zvakadaro, mitsara yekuparadzana inowanzoonekwa pachigadzirwa chekupedzisira.Liquid silicone molds inokonzerwa neiyo geometry yechigadzirwa uye nzvimbo yemutsara wekuparadzanisa.Iyo yakashongedzwa zvishoma chigadzirwa dhizaini inobatsira kuve nechokwadi chekuti chigadzirwa chine hukama hwakafanana kune inodiwa imwe hafu yegomba.
