A:Ukukhipha ingcindezi kuyindlela yokuphonsa lapho uketshezi lwengxubevange encibilikisiwe luthelwa khona egumbini lokucindezela, imbobo yensimbi igcwaliswa ngesivinini esikhulu, futhi ingxubevange yoketshezi iqiniswa ngaphansi kwengcindezi ukuze yakhe ukusakaza.Izici eziyinhloko ze-die casting eziyihlukanisa kwezinye izindlela zokulingisa ingcindezi ephezulu kanye nesivinini esikhulu.

Imishini yokufaka i-die-casting, ama-alloy asakaza i-die-casting kanye nokubunjwa kwe-die-casting yizinto ezintathu ezinkulu zokukhiqiza i-die-casting futhi zibalulekile.Inqubo ebizwa ngokuthi i-die-casting iyinhlanganisela yemvelo yalezi zakhi ezintathu, okuvumela ukukhiqizwa okuzinzile, okunesigqi futhi okuphumelelayo kokulingisa ngokubukeka, ikhwalithi enhle yangaphakathi, nobukhulu bemidwebo noma izidingo zesivumelwano.

A:

(1) Ingakwazi ukuhlangabezana nezidingo zokusebenza ze-die castings.

(2) Iphuzu lokuncibilika liphansi, izinga lokushisa elicwebezelayo lincane, i-fluidity ezingeni lokushisa elingaphezu kwendawo yokuncibilika yinhle, kanye nenani lokushwabana ngemva kokuqina lincane.

(3) Inamandla anele kanye ne-plasticity emazingeni okushisa aphezulu, futhi ine-brittleness ephansi eshisayo.

(4) Izakhiwo ezinhle zomzimba namakhemikhali ezifana nokungagugi, ukuguquguquka kukagesi, ukuqhutshwa kwe-thermal, nokumelana nokugqwala.

A: Ngokuvamile, ukusetshenziswa kwangempela embonini ye-die-casting akuyona i-aluminium ehlanzekile engu-100%, kodwa ngokuqukethwe kwe-aluminium kusuka ku-95% kuya ku-98.5% (ingxube ye-aluminium ye-die-cast esebenza kahle nge-anodizing), futhi i-aluminium ehlanzekile idinga ukuqukatha ngaphezu kwe-99.5% ye-aluminium (Efana ne-aluminium ehlanzekile ye-rotor die casting).Ngenxa ye-thermal conductivity enhle kanye nezakhiwo ze-anodizing, i-alumina ivame ukusetshenziswa kumasinki okushisa kanye nokwelashwa kwendawo lapho izidingo zombala ziphezulu.

Uma kuqhathaniswa ne-aluminium alloy die-casting evamile (njenge-ADC12), ngenxa yokuqukethwe okuphezulu kwe-silicon, izinga lokuncipha lincane kakhulu ngo-4-5%;kodwa i-alumina ngokuyisisekelo ayinayo i-silicon, izinga lokushwabana lingu-5-6%, ngakho-ke i-aluminium alloy die-casting evamile ayinawo umphumela we-anodizing.

A: Imishini yokufaka i-Die-casting ingahlukaniswa ibe yizinhlobo ezimbili, imishini yokukhipha i-hot chamber die kanye ne-cold chamber die casting machines.Umehluko usekutheni zingamelana namandla angakanani.Ingcindezi ejwayelekile isukela kumathani angama-400 kuye kwangama-4,000.I-hot chamber die casting iyinsimbi encibilikisiwe, ewuketshezi, engawuketshezi echibini lensimbi eligcwalisa isikhunta ngaphansi kwengcindezi.I-Cold die Casting ingasetshenziselwa izinsimbi zokujikijela ezingakwazi ukusetshenziswa ezinqubweni zokusakaza ze-hot chamber die, okuhlanganisa i-aluminium, i-magnesium, ithusi, ne-zinc alloys enokuqukethwe okuphezulu kwe-aluminium.Kule nqubo, insimbi idinga ukuncibilika kuqala ku-crucible ehlukile.Inani elithile lensimbi encibilikisiwe libe selidluliselwa ekamelweni lomjovo ongashisi noma umlomo wombhobho;umehluko phakathi kwegumbi elishisayo negumbi elibandayo ukuthi ngabe uhlelo lomjovo lomshini wokufa lucwiliswa esixazululweni sensimbi.

A: Umshini wokuphonsa wegumbi elishisayo: ingxubevange ye-zinc, ingxubevange ye-magnesium, njll.

Cold chamber die Casting machine: zinc alloy, magnesium alloy, aluminium alloy, copper alloy, njll.

Umshini wokuphonsa wokufa omile: i-zinc, i-aluminium, ithusi, umthofu, ithini;

A:

1. Ukusebenza kahle kokulingisa

2. Ukuminyana okuphansi (2.5 ~ 2.9 g / cm 3), amandla aphezulu.

3. Uketshezi lwensimbi olunomfutho ophakeme kanye nezinga lokugeleza okusheshayo ngesikhathi sokuphonsa ukufa

4, izinga lomkhiqizo lihle, ubukhulu buzinzile, nokushintshana kuhle;

5, ukusebenza kahle kokukhiqiza okuphezulu, inani lezikhathi lapho kusetshenziswa isikhunta se-die-casting;

I-6, ifanele inani elikhulu lokukhiqiza okukhulu, izinzuzo ezinhle zezomnotho.

A: Okuvame ukusetshenziswa ekwelapheni okungaphezulu kwezingxenye ze-aluminium alloy die-casting yilezi: upende we-electrophoretic, i-electroplating, umjovo kaphethiloli, ukuqhuma kwesihlabathi, ukuqhuma kwesibhamu, i-anodizing, i-varnish yokubhaka, izinga lokushisa eliphezulu lokubhaka i-varnish, i-anti-rust passivation nokunye.
