1 Tsamaiso ea Hot-Chamber Die Casting

Hot-chamber casting die, eo ka linako tse ling e bitsoang gooseneck casting, ke eona e tsebahalang haholo lits'ebetsong tse peli tsa ho lahla. Ts'ebetsong ena, kamore ea silindara ea mochini oa ente e qoelitsoe ka botlalo ka bate ea tšepe e qhibilihisitsoeng. Sistimi ea phepelo ea tšepe ea gooseneck e hulela tšepe e qhibilihisitsoeng kahare.

Ha ho qoelisoa ka kotloloho bateng e entsoeng ka ho qhibilihisoa ho lumella ente ea hlobo e potlakileng le e bonolo, e boetse e baka ts'oaetso ea ts'enyeho. Ka lebaka la 'nete ena, e chesang-kamoreng shoela'ng thulaganyou e loketse bakeng sa dikopo hore sebelisa tšepe le lintlha tlaase qhibiliha le fluidity phahameng. Lisebelisoa tse ntle bakeng sa ts'ebetso ea ho lahla kamore e chesang li kenyelletsa lead, magnesium, zinc le koporo.

2 Ts'ebetso ea Cold-Chamber Die Casting

Ts'ebetso ea ho lahla kamore e batang e tšoana haholo le ho betloa ha kamore e chesang. Ka moralo o shebaneng le ho fokotsa ts'enyeho ea mochini ho fapana le ts'ebetso ea tlhahiso, tšepe e qhibilihisitsoeng e itšebetsa ka boeona kapa e kenella ka letsoho tsamaisong ea ente. Sena se felisa tlhoko ea hore mochini oa ente o ineloe ka bateng ea tšepe e qhibilihisitsoeng.

Bakeng sa lits'ebetso tse senyang haholo bakeng sa moralo oa qoeliso ea bethe ea kamore e chesang, ts'ebetso ea kamore e batang e ka ba mokhoa o mong o motle. Ts'ebeliso ena e kenyelletsa ho lahla tšepe e nang le mocheso o phahameng o qhibilihang, joalo ka aluminium le aluminium alloys.

3 Ts'ebetso ea khatello ea Low-Pressure Die

Ho lahla khatello e tlase ke mokhoa o loketseng likaroloana tsa aluminium tse lumellanang hantle ho potoloha. Ka mohlala, mabili a likoloi, hangata a iqapetsoe ka ho lahla khatello e tlase ea khatello. Mofuteng ona oa tšebetso, hlobo e lutse ka tsepameng kaholimo ho bate ea tšepe e qhibilihisitsoeng mme e hokahane ka phala ea riser. Ha kamore e hatelloa (hangata e pakeng tsa 20 le 100kPa), tšepe e huleloa holimo ebe e kena ka hlobo. Ho felisoa ha li-feeder tsa mofuta ona oa ts'ebetso ea ho lahla li fana ka chai e ngata.

Lephaka khatello ea foromeletsoeng (VPC) ke batlang e le lecha thulaganyou e shoela'ng foromeletsoeng hore lopolla matlafatsoa matla le porosity fokolang haholo. Ts'ebetso ena e ts'oana le ho lahla ka khatello e tlase, ntle le ha libaka tsa hlobo ea tšepe le sesepa sa tšepe e qhibilihisitsoeng li khutlisitsoe. Kamore ea silindara e ka fetoha lephaka, le qobellang tšepe e qhibilihisitsoeng ka lehare. Moralo ona o fokotsa pherekano ebile o fokotsa palo ea kenyelletso ea khase. Lepolanka shoa lahla ke molemo haholo-holo ka dikopo reretsoe ho kalafo mora-lahla mocheso.

5 Mokhoa oa ho Squeeze Die Casting

Squeeze casting e entsoe e le tharollo e sebetsang bakeng sa ho lahla tšepe le lits'epe tse kopantsoeng tse nang le fluidity e tlase. Ts'ebetsong ena, tšepe e entsoeng ka ho qhibilihisoa e tlatsa lefi le bulehileng, le ntan'o pepeta le koalehe, le qobelle tšepe hore e kenelle likarolong tse koahetsoeng haholo tsa letsopa. Ts'ebetso ea ho lahla e fana ka lihlahisoa tse teteaneng haholo mme ke ts'ebetso e tlatselletsang ho kalafo ea mocheso e latelang. Ts'ebetso ena hangata e amahanngoa le aluminium e qhibilihisitsoeng, 'me e sebelisoa lits'ebetsong tse hlokang matlafatso ea fiber.

6 The Semi-Tiileng shoa lahla Process

Ho betla ka seka-solid, eo ka linako tse ling ho thoeng ke Thixoforming, ke ts'ebetso e 'ngoe e fanang ka porosity e nyane le bongata bo boholo. Mochini o seha mosebetsi hore o be li-slugs tse nyane ebe oa futhumala. Hang ha tšepe e se e fihlile phetohong ea mohato pakeng tsa se tiileng le mokelikeli, e leng se hlahisang sebopeho se boreleli, sleeve e thunyang e e qobella mohahong oa hlobo, moo e thatafalang. Molemo oa sena ke ntlafatso e nepahetseng. Lisebelisoa tse se nang litšepe tse kang motsoako oa magnesium le alloyum aluminium hangata li sebelisoa ka ts'ebetso ea semi-solid cast.

7. Mefuta ea Ts'ebetso ea ho lahla Die

Mefuta eohle ea ts'ebetso ea ho lahla e entsoe ka sepheo se ts'oanang kelellong-lahla hlobo ka tšepe e entsoeng ka ho qhibilihisoa. Ho ipapisitse le mofuta oa tšepe e qhibilihisitsoeng, karolo ea jiometri le boholo ba karolo, lits'ebetso tse fapaneng tsa ho betsa li ka fana ka liphetho tse phahameng ho feta mekhoa e meng. Mefuta e 'meli e meholo ea lits'ebetso tsa ho lahla li-hot-kamoreng le kamore e batang ea ho betla. Mefuta e fapaneng ea mefuta ena e 'meli ea ho lahla lefu e kenyelletsa:
