Ho lahla lehlabathe ke mokhoa o tloaelehileng oa ho lahla

Ho lahla lehlabathe ke mokhoa o tloaelehileng oa ho lahla, o tsejoang hape e le ho lahla lehlabathe.Ke mokhoa oa ho etsa li-castings ka ho sebelisa lehlabathe ka har'a hlobo ea ho lahla.

Mokhoa oa ho lahla lehlabathe o kenyelletsa mehato e latelang:

1. Ho lokisa hlobo: Etsa liforomo tse peli tse nang le li-concavities tse ntle le tse mpe ho latela sebopeho le boholo ba karolo.Mofuta o motle o bitsoa core, 'me hlobo e mpe e bitsoa sandbox.Hangata hlobo ena e entsoe ka thepa ea refractory.

2. Ho lokisa hlobo ea lehlabathe: Beha mokokotlo ka har'a lebokose la lehlabathe 'me u le tlatse ka lehlabathe la motheo ho pota-pota.Hangata lehlabathe la Foundry ke motsoako o khethehileng oa lehlabathe le letle, letsopa le metsi.Ka mor'a ho tlatsa ho phethoa, hlobo ea lehlabathe e kopantsoe ka ho sebelisa khatello kapa vibration.

3. Melting metal: Ho qhibilihisa tšepe e batloang hore e be mokelikeli, hangata ho sebelisoa sebōpi ho futhumatsa thepa ea tšepe.Hang ha tšepe e fihla sebakeng se loketseng sa ho qhibiliha, mohato o latelang o ka qala.

4. Ho tšela: Metsi a tšeloa butle-butle ka har'a hlobo ea lehlabathe, a tlatsa sebopeho sohle.Ts'ebetso ea ho tšela e hloka mocheso o laoloang le lebelo ho qoba li-bubble, li-shrinkage cavities kapa liphoso tse ling.

5. Ho Tiisa le ho Pholisa: Hang ha tšepe ea mokelikeli e ka har'a ho lahla e pholile le ho tiea, hlobo e ka buloa 'me ho tlosoa ha tšepe e tiileng ho tlosoa hlobo ea lehlabathe.

6. Ho hloekisa le ho lokisa ka mor'a ho sebetsa: Li-castings tse tlositsoeng li ka 'na tsa e-ba le lehlabathe kapa grit tse khomaretsoeng holimo' me li hloka ho hloekisoa le ho fokotsoa.Mekhoa ea mechine kapa ea lik'hemik'hale e ka sebelisoa ho tlosa grit le ho etsa ho faola le phekolo e hlokahalang.

Ho lahla lehlabathe ke mokhoa o tenyetsehang le oa moruo o loketseng ho hlahisa likarolo tsa tšepe tsa boholo bo fapaneng le libopeho.E sebelisoa haholo liindastering tse kang likoloi, mechine, sefofane le matla.

Ts'ebetso ea ho lahla lehlabathe e ka akaretsoa feela ka mehato e latelang: ho lokisa hlobo, ho lokisa lehlabathe, tšepe e qhibilihang, ho tšeloa, ho tiisa le ho pholisa, ho hloekisa le ho lokisa ka morao.

Ho lahla lehlabathe ho ka aroloa ka mefuta e latelang ho latela hlobo e fapaneng ea lehlabathe:

1. Mixed Sand Casting: Ona ke mofuta o atileng haholo oa ho lahla lehlabathe.Ha ho etsoa lehlabathe le tsoakiloeng, ho sebelisoa lehlabathe le kopantsoeng le nang le lehlabathe, binder le metsi.Mofuta ona oa lehlabathe o na le matla a holimo le nako e telele 'me o loketse ho hlahisa li-castings tse nyenyane, tse mahareng le tse kholo.

2. Binder sand casting: Mofuta ona oa ho lahla lehlabathe o sebelisa hlobo ea lehlabathe e nang le setlamo se khethehileng.Litlama li matlafatsa matla le ho tšoarella ha hlobo ea lehlabathe ha li ntse li ntlafatsa boleng ba bokaholimo le ho nepahala ha li-castings.

3. Ho lahla lehlabathe le thata: Ho chesoa ha lehlabathe le thata ho sebelisa hlobo e thata ea lehlabathe e hanyetsanang le mollo o phahameng le ho tšoarella nako e telele.Mofuta ona oa lehlabathe o loketse ho hlahisa li-castings tse kholo le tse phahameng, tse kang li-engine blocks le bases.

4. Mokhoa oa ho lahla lehlabathe ka mokhoa oa ho theola: Mofuteng ona oa ho lahla lehlabathe, ho sebelisoa mekhoa e fapaneng ea ho phunya lehlabathe ho etsa hore ho lokisoa le ho nka hlobo ea lehlabathe ho be bonolo haholoanyane.Mekhoa e tloaelehileng ea ho lokolla e kenyelletsa ho lahla lehlabathe le letala, ho lahla lehlabathe le omeletseng le ho lahla lehlabathe la moemeli.

5. Ho lahla lehlabathe la mohlala: Ho lahla lehlabathe la mohlala ke mokhoa oa ho lahla lehlabathe o sebelisang hlobo e tsamaeang.Mokhoa ona o loketse ho hlahisa li-castings tse nang le libopeho tse rarahaneng le likarolo tsa ka hare tsa cavity, tse kang li-gear le li-turbine.

Ka holimo ke ts'ebetso e akaretsang le lihlopha tse tloaelehileng tsa ho lahla lehlabathe.Ts'ebetso e ikhethileng le likarolo li ka fetoha ho latela litlhoko le lisebelisoa tse fapaneng.
