Ndezvipi zvinhu zvepurasitiki mold cavity?

Iyo plastiki mold cavity material inoreva zvinhu zvinoshandiswa kugadzira chikamu chegomba chepurasitiki.Akasiyana epurasitiki mold anoshandisa akasiyana mhango zvinhu kusangana nezvinodiwa zvakasiyana uye zvinodiwa.

Izvi zvinotevera 5 zvakajairika epurasitiki mold cavity zvinhu:

(1) Chishandiso chesimbi zvinhu: Chishandiso simbi ndeimwe yeanowanzo shandiswa epurasitiki mold mhango zvinhu.Iyo ine kuoma kwakanaka, kupfeka kuramba uye corrosion kuramba, uye inogona kumira jekiseni kuumba maitiro pasi pekushisa kwepamusoro uye mamiriro ekumanikidza.Common tool steels dzinosanganisira P20 (inozivikanwa se3Cr2Mo muChina), 718 (inozivikanwa se3Cr2NiMo muChina) nezvimwe zvakadaro.

(2) Stainless simbi zvinhu: Stainless simbi imwe inowanzoshandiswa plastiki mold gomba zvinhu.Simbi isina tsvina ine yakakwira corrosion resistance uye oxidation resistance, iyo inokodzera kurapwa kwezvinhu zvepurasitiki zvine acidic kana alkaline ingredients.Zvakajairika Stainless simbi zvinhu SUS420, SUS304 uye zvichingodaro.

(3) Aluminium alloy material: Aluminium alloy iine huremu uye yakanaka yekupisa conductivity zvinhu, yakakodzera kugadzira molds hombe kana mold ine huremu hunodiwa.Aluminium alloys ane high thermal conductivity, iyo inobatsira kukurumidza kutonhora kwemapurasitiki.Yakajairika aluminium alloy zvinhu ndeye ADC12, 6061 uye zvichingodaro.

(4) Copper alloy zvinhu: Copper alloy ine yakanaka yekupisa conductivity uye kupfeka kuramba, yakakodzera kugadzira mold pasi pekupisa kwakanyanya uye yakanyanya kudzvanywa mamiriro.Copper alloys inogona kupa zvirinani kupisa kupisa uye kubatsira kudzora kutonhora kwemapurasitiki.Common mhangura alloy zvinhu H13, CuBe2 uye zvichingodaro.

(5) Zvishandiso zvepolymer: Pamusoro pezvinhu zvesimbi, kune zvimwe zvinhu zvepolymer zvinogona zvakare kushandiswa kugadzira chikamu chegomba chepurasitiki mold.Semuyenzaniso, polyimide (PI), polytetrafluoroethylene (PTFE) uye mamwe ane yakanakisa tembiricha kuramba uye ngura kuramba, akakodzera kurapa tembiricha mapurasitiki kana akakosha epurasitiki zvinhu.

Zvakakosha kusarudza zvakakodzeraplastiki moldcavity zvinhu zvinoenderana nezvinodiwa zvekushandisa uye hunhu hwepurasitiki zvinhu.Zvishandiso zvakasiyana zvine hunhu hwakasiyana uye chiyero chekushandisa, kune akasiyana majekiseni zvigadzirwa uye zvinodiwa zvekugadzira, kusarudza iyo chaiyo cavity zvinhu chinhu chakakosha kuve nechokwadi chekuita mold uye hupenyu.
