Shell Mold Casting Maitiro

Shell-mold casting process inozivikanwawo seshell molding process. Iyo inogoneka yekukanda mold process inoshandisa resin yakavharwa jecha kugadzira mold. Mukuita kukanda ganda-mold mold inogadzirwa sedeko. Iyo yakaonda kana mhango mold inoshandiswa kuitira kuti huremu hwehuremu huve hushoma uye kubata kwe mold kuve nyore.

Kugadzira iyo yakaonda mold, iyo phenolic resin ine diki yekuwedzera ye silica jecha inoshandiswa seyakaumbwa zvinhu. Pakugadzira shell-mold casting inoda kushandiswa kwesimbi pateni, ovheni, jecha-resin musanganiswa, dump box uye simbi yakanyungudutswa.Shell-mold kukandainobvumira kushandiswa kwezvose zviri zviviri ferrous uye non-ferrous simbi, anonyanya kushandiswa simbi dzakanyungudutswa varigrey cast iron, ductile cast iron, carbon steel,alloy simbi, Stainless simbi, aruminiyamu alloys uye copper alloys.

Matanho eShell Mold Casting

1. Kusikwa kwemuenzaniso - Chimiro chesimbi-maviri chinogadzirwa muchimiro chechimiro chinodiwa chinodiwa.
2. Kusikwa kweMold - Kutanga, imwe neimwe hafu yemuenzaniso inopisa kusvika 175-370 ° C uye yakaputirwa nemafuta kuitira kuti zvive nyore kuparadzana kubva pamuenzaniso wakagadzirwa. Tevere, iyo inopisa patani inosungirirwa kubhokisi rekurasa. Bhokisi rekurasira rakatenderedzwa, richibvumira uyu musanganiswa wejecha-resin kuti upfeke patani. Iyo inopisa pateni inoporesa musanganiswa, iyo zvino inoumba goko rakatenderedza pateni. Imwe neimwe pateni hafu uye yakatenderedza goko inorapwa kuti ipedze muchoto uye ipapo goko rinoburitswa kubva patani.
3. Mold assembly - Mahafu maviri emateko anobatanidzwa pamwe chete uye akasungirirwa zvakachengetedzeka kuti agadzire mold yakazara. Kana paine macores anodiwa, anoiswa asati avhara mold. Iyo shell mold inozoiswa muflask uye inotsigirwa nezvinhu zvinotsigira.
4. Kudira - Mold inosungirirwa pamwe chete zvakachengeteka uku simbi yakanyungudutswa ichidirwa kubva muladhi kupinda mugeti system uye inozadza mhango.
5. Kutonhora - Mushure mokunge mold yazadzwa, simbi yakanyungudutswa inobvumirwa kutonhora uye kusimba muchimiro chekukanda kunoda.
6. Kubvisa kukanda - Mushure mokunge simbi yakanyungudutswa yatonhodzwa, mold inoputsika uye kukanda kunobviswa. Kucheka nekuchenesa maitiro anoitwa kuti abvise chero simbi yakawandisa kubva kune yekudyisa system uye kupatsanura madiki jecha zvidimbu kubva muforoma.

Zvimiro zveShell Molding process:

• • Mugoko rekuumba ukobvu uye huremu hweforoma hushoma.
• • Mwero wekugadzirwa kwegoko rakakwirira kwazvo.
• • Nekuda kwekuderera porosity ye mold, kuburikidza ne riser inofanira kushandiswa.
• • Inobatsira chete denderedzwa uye symmetrical mabasa.
• • Zvimiro zvakaoma zvikuru hazvigoni kuumbwa uchishandisa shell mold casting nzira.
• • Maitirwo aya anoburitsa kukanda kwakaringana kwedimensional zvichienzaniswa nekumwejecha kukanda nzira.
• • Makona epasi anogona kushandiswa.
