Chii chinonzi Aluminium Die Casting
Overview: Chiialuminium die casting?
Izvo zvekutanga zvealuminium die casting
Aluminium die casting inzira yekugadzira yekugadzira yakanyatso mativi, yakatsanangurwa zvakanyanya, yakatsetseka kana yakashongedzwa-yepamusoro-pamusoro pearuminiyamu zvikamu kuburikidza nekushandiswa kweanogona kushandiswazve mold, inonzi inofa.Iyo aluminium kufa yekukanda maitiro inosanganisira kushandiswa kwechoto, aruminiyamu alloy, die casting muchina, uye kufa.Mafaro anowanzo vakwa neanogara kwenguva refu, simbi yemhando yepamusoro ane zvikamu zviviri zvinobvumidza kubviswa kwekukandwa.
Aluminium die casting inoshanda sei?
Iyo aluminium casting inofa iyo inogadzirwa neyakaomeswa simbi simbi inofanirwa kugadzirwa mune inokwana zvikamu zviviri kuitira kuti castings ibviswe.Iyo aluminium die casting process inokwanisa kugadzira makumi ezviuru zvearuminiyamu castings mukukurumidza kutevedzana.Iwo madhiri akaiswa zvakasimba mumuchina wekukanda kufa.Iyo yakagadziriswa hafu inofa yakamira.Imwe yacho, injector die half, inofambiswa.Aluminium inokandira inofa inogona kuve yakapusa kana yakaoma, ine inofambiswa masiraidhi, cores kana zvimwe zvikamu, zvichienderana nekuoma kwekukanda.Kutanga maitiro ekukanda kufa, mahafu maviri anofa anosungirirwa pamwechete nemuchina wekukanda.Yepamusoro tembiricha yemvura aruminiyamu alloy inopinzwa mugomba rekufa uye nekukurumidza kusimba.Ipapo iyo inofambiswa die hafu inovhurwa uye iyo aluminium kukanda inoburitswa.
INDUSTRIES
Maindasitiri anoshandisa aluminium kufa casting
Aluminium die casting parts anoshandiswa zvakanyanya mumotokari, imba, zvemagetsi, simba, kuvaka uye maindasitiri.
Mold kana tooling
Maviri maviri anoshandiswa mukukanda kufa;imwe inonzi "cover die half" uye imwe yacho "ejector die half".Pavanosangana panonzi mutsetse wekuparadzana.Iyo yekuvhara inofa ine sprue (yemichina inopisa-yekamuri) kana gomba repfuti (yemichina inotonhora-yekamuri), iyo inobvumira simbi yakanyungudutswa kuti iyerere muinofa;chinhu ichi chinopindirana nejekiseni nozzle pamichina yekamuri inopisa kana kamuri yekupfura mumichina yekamuri inotonhora.Iyo ejector inofa ine ejector pini uye kazhinji mumhanyi, inova nzira kubva kune sprue kana pfuti gomba kuenda kugomba.Iyo yekuvhara inovharirwa kune yakamira, kana kumberi, platen yemuchina wekukanda, nepo ejector inofa yakanamatira kune inofambiswa platen.Iyo mold mhango inochekwa kuita maviri mhango inopinza, ari zvidimbu zvakaparadzana zvinogona kutsiviwa zviri nyore uye bhaudhi mumahafu ekufa.
Iyo inofa yakagadzirirwa kuitira kuti iyo yakapedzwa kukanda inotsvedza kubva pavhavha yehafu yefa uye igare mu ejector hafu sezvo iyo inofa inovhurwa.Izvi zvinovimbisa kuti kukanda kunoraswa kutenderera kwese nekuti ejector hafu ine ejector mapini ekusundidzira kukanda kunze kwehafu iyo inofa.Mapini ejector anofambiswa ne ejector pin plate, iyo inonyatso tyaira mapini ese panguva imwe chete uye nesimba rimwechete, kuitira kuti kukanda kusakuvadzwa.Iyo ejector pini ndiro zvakare inodzoreredza mapini mushure mekukanda kukanda kugadzirira kupfura kunotevera.Panofanira kunge paine mapini ejector akakwana kuchengetedza simba rese papini yega yega yakadzikira, nekuti kukanda kuchiri kupisa uye kunogona kukuvadzwa nesimba rakawandisa.Mapini acho achiri kusiya mucherechedzo, saka anofanirwa kunge ari munzvimbo iyo aya mavanga asingazokanganisa chinangwa chekukanda.
Zvimwe zvikamu zvekufa zvinosanganisira macores uye masiraidhi.Cores zvinhu zvinowanzoburitsa maburi kana kuvhurika, asi zvinogona kushandiswa kugadzira zvimwewo.Kune marudzi matatu emacores: anogadzika, anofambiswa, uye akasununguka.Fixed cores ndeaya anotariswa anoenderana nekudhonza nzira yefa (kureva iyo inofa yakavhurika), saka inogadziriswa, kana yakanamatira zvachose kune iyo kufa.Movable cores ndeaya anotariswa neimwe nzira kunze kwekuenderana negwara rekudhonza.Aya macores anofanirwa kubviswa kubva mugomba rekufa mushure mekunge pfuti yasimba, asi isati yafa yakavhurika, uchishandisa imwe nzira.Masiraidhi akafanana neanofamba cores, kunze kwekunge anoshandiswa kugadzira undercut surface.Kushandiswa kwemacores uye masiraidhi kunowedzera zvakanyanya mutengo wevanofa.Loose cores, anonziwo pick-outs, anoshandiswa kukanda zvinhu zvakaoma kunzwisisa, semaburi ane threaded.Aya akasununguka cores anopinzwa mufa neruoko pamberi pese kutenderera uye anobva aburitswa nechikamu pakupera kwekutenderera.Nheyo ipapo inofanira kubviswa nemaoko.Loose cores ndiyo inonyanya kudhura mhando yepakati, nekuda kwekuwedzera kwekushanda uye kuwedzera kutenderera nguva.Zvimwe zviri mudhiya zvinosanganisira nzira dzinotonhorera dzemvura uye mavhavha ari pamitsetse yekuparadzana.Magetsi aya anowanzo kupamhama uye akatetepa (inenge 0.13 mm kana 0.005 mukati) zvekuti kana simbi yakanyunguduka ikatanga kuazadza simbi yacho inokurumidza kuoma uye kuderedza zvimedu.Hapana ma risers anoshandiswa nekuti kudzvanywa kwepamusoro kunovimbisa kuenderera kwekudya kwesimbi kubva kugedhi.
Izvo zvakakosha zvezvinhu zvivakwa zvemafa ndeye thermal shock resistance uye kupfava pane yakakwirira tembiricha;zvimwe zvakakosha zvinhu zvinosanganisira kuoma, machinability, kupisa kutarisa kuramba, weldability, kuwanikwa (kunyanya kune yakakura inofa), uye mutengo.Hurefu hwehupenyu hwekufa hunoenderana zvakananga nekupisa kwesimbi yakanyungudutswa uye nenguva yekutenderera.[16]Iyo inofa inoshandiswa mukukanda kufa inowanzogadzirwa nesimbi dzakaomeswa, nekuti simbi yakakandwa haigone kumirisana nekumanikidza kwakanyanya kunosanganisirwa, saka iyo inofa inodhura zvakanyanya, zvichikonzera kukwira kwemitengo yekutanga.Masimbi anokandwa patembiricha yepamusoro anoda anofa akagadzirwa kubva pakakwirira alloy simbi.
Iyo huru yekutadza maitiro ekukanda kufa kufa ndeye kupfeka kana kukukurwa.Mamwe maitiro ekutadza kutarisa kupisa uye kuneta kwekupisa.Kuongorora kupisa ndipo panoitika pakatsemuka pamusoro pekufa nekuda kwekuchinja kukuru kwetembiricha pane yega kutenderera.Thermal kuneta ndeye apo kutsemuka kwepamusoro kunoitika pafa nekuda kwenhamba yakawanda yematenderedzwa.
