A: Uxinzelelo loxinzelelo yindlela yokuphosa apho i-alloy liquid etyhidiweyo igalelwe kwigumbi loxinzelelo, i-cavity ye-mold yensimbi izaliswe ngesantya esiphezulu, kwaye i-alloy liquid iqiniswe phantsi koxinzelelo ukuze yenze i-casting.Iimpawu eziphambili ze-die casting ezahlula kwezinye iindlela zokuphosa luxinzelelo oluphezulu kunye nesantya esiphezulu.

Oomatshini bokuphosa i-die-casting, i-alloys yokuphosa kunye nokubumba okufayo zizinto ezintathu eziphambili zemveliso ye-die-casting kwaye ziyimfuneko.Inkqubo ebizwa ngokuba yi-die-casting yindibaniselwano yendalo yezi zinto zintathu, eyenza ukuveliswa okuzinzileyo, okunesingqisho kunye nokusebenza kakuhle kwe-castings kunye nenkangeleko, umgangatho omhle wangaphakathi, kunye nobukhulu bemizobo okanye iimfuno zesivumelwano.

A:

(1) Inokuhlangabezana neemfuno zokusebenza kwee-die castings.

(2) Indawo yokunyibilika iphantsi, iqondo lobushushu becrystallization lincinci, ulwelo olukwiqondo lobushushu ngaphezu kwendawo yokunyibilika lulungile, kwaye ubungakanani bokuncipha emva kokuqiniswa buncinci.

(3) Inamandla okwaneleyo kunye neplastikhi kumaqondo obushushu aphezulu, kwaye ine-brittleness eshushu ephantsi.

(4) Iimpawu ezilungileyo zomzimba kunye neekhemikhali ezifana nokunganyangeki, ukuhanjiswa kombane, ukuqhutyelwa kwe-thermal, kunye nokumelana nokubola.

A: Ngokuqhelekileyo, usetyenziso lwangempela kwishishini lokuphosa i-die-casting aluyi-100% i-aluminium ecocekileyo, kodwa inomxholo we-aluminium ukusuka kwi-95% ukuya kwi-98.5% (i-alloy ye-aluminium ye-die-cast kunye nokusebenza kakuhle kwe-anodizing), kunye ne-aluminium ecocekileyo kufuneka iqulethe. ngaphezu kwe-99.5% ye-aluminium (Efana ne-aluminium ecocekileyo ye-rotor die casting).Ngenxa yokusebenza kakuhle kwe-thermal kunye neempawu ze-anodizing, i-alumina isoloko isetyenziswa kwiindawo zokuhlambela ubushushu kunye nonyango lomphezulu apho iimfuno zombala ziphezulu.

Xa kuthelekiswa ne-aluminium eqhelekileyo ye-alloy-alloy-casting (efana ne-ADC12), ngenxa yomxholo ophezulu we-silicon, izinga lokunciphisa lincinci kwi-4-5%;kodwa i-alumina ngokusisiseko ayikho i-silicon, izinga lokucutheka yi-5-6%, ngoko ke i-alloy ye-aluminiyam eqhelekileyo i-die-casting ayinayo i-anodizing effect.

A: Oomatshini be-Die-casting banokohlulwa babe ziindidi ezimbini, oomatshini bokuphosa kwigumbi elishushu kunye negumbi elibandayo lokufa koomatshini.Umahluko uxhomekeke ekubeni angakanani amandla anokumelana nawo.Uxinzelelo oluqhelekileyo lusuka kwi-400 ukuya kwi-4,000 yeetoni.Hot chamber die casting yintsimbi etyhidiweyo, ulwelo, isiqingatha solwelo kwichibi lesinyithi eligcwalisa ukungunda phantsi koxinzelelo.Ukuphosa ukufa okubandayo kungasetyenziselwa iintsimbi zokuphosa ezingenakusetyenziswa kwiinkqubo zokuphosa egumbini elishushu, kuquka i-aluminiyam, i-magnesium, ubhedu, kunye ne-alloys ye-zinc enomxholo ophezulu we-aluminium.Kule nkqubo, isinyithi kufuneka sincibilike kuqala kwi-crucible eyahlukileyo.Isixa esithile sesinyithi esinyibilikisiweyo sidluliselwe kwigumbi lokutofa elingenabushushu okanye emlonyeni;Umahluko phakathi kwegumbi elishushu kunye negumbi elibandayo kukuba ingaba inkqubo yokutofa yomshini wokufa ifakwe kwisisombululo sesinyithi.

A: Igumbi elitshisayo lokuphosa umatshini wokuphosa: i-zinc alloy, i-magnesium alloy, njl.

Umatshini wokuphosa wegumbi elibandayo: i-zinc alloy, i-magnesium alloy, i-aluminium alloy, i-alloy yobhedu, njl.

Umatshini wokuphosa wokufa othe nkqo: i-zinc, i-aluminiyam, ubhedu, ilothe, itoti;

A:

1. Ukusebenza kakuhle kokuphosa

2. Ubuninzi obuphantsi (2.5 ~ 2.9 g / cm 3), amandla aphezulu.

3. Ulwelo lwesinyithi olunoxinzelelo oluphezulu kunye nesantya sokuhamba ngokukhawuleza ngexesha lokufa

I-4, umgangatho wemveliso ulungile, ubungakanani buzinzile, kunye nokutshintshana kuhle;

I-5, ukusebenza kakuhle kwemveliso, inani lamaxesha asetyenziswa ngundo wokufa;

I-6, ilungele inani elikhulu lemveliso enkulu, imbuyekezo elungileyo yezoqoqosho.

A: Ngokuqhelekileyo isetyenziselwa unyango olungaphezulu lwe-aluminium alloy die-casting parts are: peyinti ye-electrophoretic, i-electroplating, i-injection ye-fuel, i-sand blasting, i-shot blasting, i-anodizing, i-varnish yokubhaka, i-varnish yokushisa ephezulu, i-anti-rust passivation kunye nokunye.
