1.2 Kuongorora kwemaitiro
Low pressure die casting inzira yakakosha yekukanda pakati pekukandira nekukandira giravhiti.Izvo hazvina chete zvakanakira kushandisa simbi molds kune ese ari maviri, asiwo ine maitiro ekuzadza kwakadzikama.Low pressure die casting ine mabhenefiti ekudzika-kumhanya kuzadza kubva pasi kusvika kumusoro, nyore kudzora kumhanya, kudiki kadhi uye kupfapfaidza kwealuminium yemvura, shoma oxide slag, yakakwira tishu density uye yakakwira michina zvinhu.Pasi peyakaderera kukanda kufa, iyo aluminium yemvura inozadzwa zvakanaka, uye iyo inokanda inoomesa uye inopenya pasi pekumanikidzwa, uye kukanda neyakaomesesa chimiro, yakakwira michina zvimiro uye chitarisiko chakanaka chinogona kuwanikwa, icho chakakodzera kugadzira mahombe akatetepa-akakomberedzwa. .
Zvinoenderana nemidziyo yemagetsi inodiwa nekukanda, iyo yekukanda zvinhu ndeye A356, iyo inogona kusangana nezvinodiwa nevatengi mushure mekurapwa kweT6, asi kudururwa kwemvura yechinhu ichi kunowanzoda kudzora kunonzwisisika kwekushisa kwe mold kuti ibudise yakakura uye yakatetepa castings.

Mufananidzo 5 (Kuenzanisa kwe shrinkage porosity defects mushure mekusimbiswa)
Mhedzisiro yemhedzisiro yezvirongwa zviviri zviri pamusoro inoratidza kuti iyo aluminium yemvura iri mugomba inokwira ichikwira ichida kufanana, inofambirana nedzidziso yekuzadza kwakafanana kwealuminiyamu yemvura yakazara, uye inofananidzirwa shrinkage porosity zvikamu zvekukanda ndizvo. inogadziriswa nekusimbisa kutonhora uye dzimwe nzira.
Zvakanakira zvirongwa zviviri izvi: Tichitarisa kubva kune tembiricha yearuminiyamu yemvura panguva yekufananidzwa yekuzadza, tembiricha yekuguma kwekukanda kwakaumbwa nechirongwa 1 ine yakakwira yunifomu pane iyo yechirongwa 2, iyo inobatsira pakuzadzwa kwegomba. .Iyo yekukanda inoumbwa nechirongwa 2 haina gedhi residu sechirongwa 1. shrinkage porosity iri nani pane yechirongwa 1.
Zvikanganiso zvezvirongwa zviviri: Nokuti gedhi rakarongeka pakukanda kunofanira kuumbwa muchirongwa 1, pachava negedhi rasara pakukanda, iyo ichawedzera inenge 0.7ka kana ichienzaniswa nekukanda kwepakutanga.kubva kune tembiricha yealuminium yemvura muchirongwa 2 yakateedzerwa kuzadza, tembiricha yealuminium yemvura kumagumo yatove yakaderera, uye simulation iri pasi peyakanaka mamiriro ekushisa kwe mold, saka kuyerera kwemvura yealuminium inogona kunge isina kukwana mukati. iyo chaiyo mamiriro, uye pachava nedambudziko rekuomerwa mukukanda kuumbwa.
Yakasanganiswa nekuongororwa kwezvinhu zvakasiyana-siyana, chirongwa chechipiri chakasarudzwa senzira yekudira.Tichifunga nezvekukanganisa kwechirongwa che2, iyo yekudurura sisitimu uye yekudziya system inogadziriswa mukugadzira mold.Sezvinoratidzwa muMufananidzo 6, iyo inoputika inokwira inowedzerwa, iyo inobatsira pakuzadza kwealuminium liquid uye inoderedza kana kudzivisa kuitika kwehurema mumakanda akaumbwa.
