Die Casting

Chii chinonzi Metal Die Casting?

Die Casting (Die Casting) zvinoreva nzira yekugadzira simbi inoumbwa ne mold.Iyi nzira inobvumira zvigadzirwa kuti zviitwe pachiyero chekugadzira hukuru nemhando yepamusoro uye kudzokorora.Maitiro acho anotanga nekumanikidza simbi yakanyungudutswa pasi pekumanikidzwa kwepamusoro kupinda mukanda akafa.Iyo inofa inogona kunge iine imwe kana yakawanda cavities (makomba ndiwo molds inogadzira chikamu chimiro).Kamwe simbi yakasimbiswa (nekukurumidza se20 masekonzi) ipapo kufa kwakavhurwa uye pfuti (magedhi, vamhanyi uye zvikamu zvese zvakabatana) zvinobviswa uye maitiro anotanga zvakare.Kutevera kuvhiyiwa kwekufa, pfuti inowanzogadziriswa zvakare pane trim kufa uko masuwo, vamhanyi uye flash zvinobviswa.Ipapo chikamu chinogona kugadziridzwa zvakare nekuzunguza deburring, kupfura kuputika, machining, pendi, nezvimwe.

Zvakanakira Die Casting

Aluminium die casting ndiyo inonyanya kufarirwa kugadzira zvikamu zvealuminium zvekukanda zvinoshandiswa mumaindasitiri akasiyana.Sezvo aruminiyamu ine yakanakisa kuyerera kwezvinhu, inoonda zvakanyanya uye yakakwira dimensional kugadzikana ine zvikamu zvakaoma zvakaumbwa.

Aluminium die casting part yakakwira mechanical simba, iri nyore kukanda, uye ine mutengo wakaderera uchienzaniswa nezinc kana magnesium die casting parts.

Aluminium die casting parts ane zvinhu zvikuru zvemuviri zvinoshingirira tembiricha yakakwira, izvo zvinoita kuti kukanda kwealuminium kugone kushandiswa mumotokari, ndege, mishonga, uye zvimwe zvigadzirwa zvemaindasitiri.

Matanho mashanu

Nhanho 1. Kunyunguduka kwezvinhu

Sezvo aruminiyamu iine yakanyanya kunyungudika (660.37 ° C) isingakwanise kunyungudutswa mukati memuchina wekukanda kufa.Ichi ndicho chikonzero nei tichifanira kufanonyungudutswa nechoto chinosungirirwamuchina unofa.

Danho 2. Mold Tool Mounting uye Clamping

Yakada kufanana nekuumbwa kwejekiseni, iyo yekukanda yekufa inodawo mold chishandiso chekukanda.Naizvozvo, isu tinofanirwa kukwirisa iyo die casting mold tool pane inotonhora yekukanda kufamuchina.

Danho 3. Jekiseni kana Kuzadza

Iyo yakanyungudutswa inotamiswa kubva muchoto kuti inofa yekukandira muchina neladle inofambiswa.Mune ino nhanho, zvinhu zvichadururwa nekumanikidzwa kupinda mufa yekukanda mold mugodhi umozvinhu zvinotonhora uye zvinoomesa kuti uwane zvinoshuvirwa kufa zvekukanda zvigadzirwa.

Nhanho 4. Kutonhorera uye Kubatana

Mushure mekufa yekukanda mold chishandiso chazadzwa zvizere nezvinhu zvakanyungudutswa, zvinotora 10 ~ 50 masekondi kutonhora uye kusimba (zvinoenderana nechikamu chimiro uye saizi).

Danho 5. Chikamu Ejection

Kana mold ichivhurwa, zvikamu zvakakandwa zvaizoburitswa nemapini ejection kubva ku die casting mold tool.Zvadaro zvikamu zvakakandwa zvakabikwa zvakagadzirira.
