Ukuhlaziywa kokusebenza kwesikhunta sokufa okufa-sokuxhuma kwepuleti ezintathu1

Ukuhlaziywa kwenqubo yokuphonsa

Ingxenye yeBracket, eyenziwe nge-ZL103 Alloy, inesimo esiyinkimbinkimbi esinezimbobo eziningi kanye nobukhulu obuncane. Lokhu kubeka izinselelo ngesikhathi senqubo ye-Ejection, ngoba kunzima ukusunduza ngaphandle kokudala izindaba zokubekezelela noma ezibucayi. Ingxenye idinga ukunemba okuphezulu okuphezulu kanye nekhwalithi ephezulu, okwenza indlela yokudla, ukondla isikhundla, kanye nengxenye ukucatshangelwa okubalulekile ekubumbeni okubunjiwe.

Isikhunta esijeziswa esifakileyo, esiboniswa kuMfanekiso 2, samukela uhlobo lwepuleti ezintathu, isakhiwo esihlukanisiwe esinezingxenye ezimbili, sinesikhungo sokwelulwa esiseduze nesango lamaphuzu. Lo mklamo uveza imiphumela emihle kakhulu nokubukeka okuhehayo.

Ekuqaleni, kwakusetshenziswa isango eliqondile kubumbi ofakayo. Kodwa-ke, lokhu kwaphumela ebunzimeni ngesikhathi sokususwa kwezinto eziseleyo, okuthinta ikhwalithi yendawo ephezulu ye-casting. Ngaphezu kwalokho, imithambo ye-shrinkage yaqashelwa esangweni, engazange ihlangabezane nezidingo zokuphonsa. Ngemuva kokucabangisisa ngokucophelela, kwakhethwa isango lokuthola amaphuzu njengoba lalibonisa ukukhiqiza izindawo ezibushelelezi ezinezinto eziphilayo nezinhlaka zangaphakathi eziminyene. Isango elingaphakathi lisethwe ngo-2mm, futhi ukuguqulwa kwenguquko kwe-H7 / M6 kwamukelwa phakathi kwesango elihlaselayo kanye nepuleti lesihlalo esilungisiwe. Ingaphezulu langaphakathi lesango lenziwa libushelelezi ngangokunokwenzeka ukuze liqinisekise ukuhlukaniswa okufanele kwe-condensate esiteshini esikhulu, ngokuqina kwe-ra = 0.8μm.

Isikhunta sisebenzisa izindawo ezimbili zokuhlukanisa ngenxa yokulinganiselwa kohlelo lwe-Gating System. Ukuhlukaniswa komhlaba ngisetshenziselwa ukuhlukanisa impahla esele esikhwameni se-sprue, kuyilapho ukuhlukanisa i-surfarg II kunesibopho sokususa izinto eziseleyo endaweni yokuphonsa. Ipuleti elixakile ekugcineni kwentonga ye-tie kusiza ukuhlukaniswa okulandelanayo kwezindawo ezimbili zokuhlukanisa, kuyilapho induku ye-tie igcina ibanga elifunayo. Ubude bomsindo womlomo (izinto ezisele ezihlukaniswe yi-Sprue Sleeve) kulungiswe ukuze kusizakale kwinqubo yokususa.

Ngesikhathi sokuhlukanisa, okuthunyelwe komhlahlandlela okuvela emgodini womhlahlandlela wethempeli elishukumisekayo, okuvumela i-mold cavity ukuthi ibekwe yi-nylon plunger efakwe kwithempulethi eshukumekayo.

Umklamo wokuqala wokubumba wafaka induku yesikhathi esisodwa yokuphuma endabeni. Kodwa-ke, kuholele ekulimaleni nasekubumbeni usayizi ekulahlekelweni okunciphileyo, okude ngenxa yamandla akhulayo okuqinisa esikhuleni esishukumisayo sesikhunta. Ukwethulwa kwalolu daba, kwethulwa ukusunduzwa kwesibili. Isikhunta sifaka isakhiwo sokuxhumeka kwe-hinge, sivumela ukunyakaza okukodwa kwamapuleti aphezulu nangaphansi wokucindezela ngesikhathi sokucindezela kokuqala. Lapho ukunyakaza kudlula unhlangothi, ukugoba kwe-hinge, futhi amandla enduku kaRod asebenza kuphela epuletini ephansi, avimba ukunyakaza kwepuleti ephezulu yokucindezela kwesibili.

Inqubo yokusebenza yoMuld ifaka phakathi umjovo osheshayo we-alloy ewuketshezi ngaphansi kwengcindezi, elandelwa ukuvulwa kobumba ngemuva kokwakhiwa. Ukuhlukaniswa kokuqala kwenzeka e-I-I Hlanganisa indawo, lapho okuqukethwe okusele esangweni kuvinjelwa umkhono we-sprue. Isikhunta siyaqhubeka ukuvula, futhi izinto ezisele ezivela ku-Imana zidilizwa. Indlela ye-Ejection yabe isiqala i-push yokuqala, lapho amapuleti aphansi nangaphezulu aqhubekela phambili aqhubekela phambili ngokuvumelanisa. Ukuphonswa kwenkanuko kudonswa kahle kude nepuleti elinyakazayo kanye nesikhungo esinqunyelwe isikhunta, ukuvumela ukudonswa komgogodla kokufakwa okuhleliwe. Njengoba ishaft ye-PIN ihamba kude nebhulokhi yomkhawulo, igoba esikhungweni sesikhunta, okwenza ipuleti eliphezulu liphelelwe amandla. Kamuva, yiplate ephansi kuphela eqhubeka nokuqhubekela phambili, ecindezela umkhiqizo ngaphandle komkhiqizo wepuleti ye-push ngokusebenzisa ishubhu le-push bese uqeda induku. I-Ejection Mechanism ihlele kabusha ngesikhathi sokuvalwa kwesikhuya ngesenzo se-Reset Lever.

Ngesikhathi sokusetshenziswa kokubumba, indawo yokuphonsa ekuqaleni yabonisa i-mesh burr, eyandiswa kancane kancane nomjikelezo ngamunye wokufa. Ucwaningo luhlonze izinto ezimbili ezifaka isandla kulolu daba: Umehluko omkhulu wokushisa wokulwa nokungafani okuvuthayo. Ukubhekana nalokhu kukhathazeka, isikhunta saphinde sashiswa saba ngu-180 ° C ngaphambi kokusebenzisa futhi sagcina ubulukhuni bendawo (i-RA) ka-0.4μm. Lezi zinyathelo zithuthuke kakhulu ngekhwalithi yokuphonsa.

Ngenxa yokwelashwa kwe-nitriding kanye nokwelashwa okufanele kanye nemikhuba yokupholisa, indawo yokupholisa ye-mold's ijabulela ukumelana nokugqoka okuthuthukile. Ukucindezela kwengcindezi kwenziwa njalo ngemijikelezo eyi-10,000 yokufa, kuyilapho i-polishing ejwayelekile kanye ne-nitriding ekhuphula khona isikhathi sokuphila kwesikhunta. Kuze kube manje, isikhunta siqede ngempumelelo imijikelezo engaphezu kuka-50 000 yokufa, okubonisa ukusebenza kwayo okunamandla nokwethembeka.
