Inqubo yesihlabathi se-Resin, umnyombo wesihlabathi uhlanganiswe nesihlabathi somgogodla, futhi kukhona iziphambeko ezimnandi esimweni se-caring sand. Ungayiqeda Kanjani?

Enqubweni yesihlabathi se-resin, lapho usebenzisa i-cores yesihlabathi ehlanganisiwe, imibukiso yokuphonsa "emnandi" ekulimaleni endaweni eyisisekelo. Yini isizathu salesi sici?

1, izici ezingenzeka ngenxa yezinkinga

1 Izizathu zingafaka: Inqubo engalungile yokuvula: izinga lokushisa eliphansi lokushisa, isikhathi sokushisa esilwanele, noma ukufudumeza okungekho emthethweni, okuholela ekuhlolweni okungaphelele kwesisekelo sesihlabathi ("ngaphansi komgogodla ophansi), umnyombo we-crispy, namandla aphansi. Izingqinamba zekhwalithi ezinesihlabathi esimisiwe: ikhwalithi embi yesihlabathi eluhlaza, okuqukethwe okuphansi kwe-resin, ikhwalithi ephansi ye-resin (njengamandla aphansi aphansi), ukuxutshwa kwesihlabathi okuphansi, ukuxubana okuholela ekushayweni komswakama ngenxa yesikhathi sokugcina isikhathi eside). Izinkinga Zomklamo we-Sand Core: Umgogodla wesihlabathi umnciphisi omkhulu, odongeni olubi kakhulu, noma oluyinkimbinkimbi, noma ehlelekile, futhi ukuqina kwalo ukuqina akwanele. I-CORE SENIED Gap / Positioning Themess: Igebe eliphakeme leNhlokodolobha Eyisisekelo Igebe eliphakathi kwamakhanda asemqoka lincane kakhulu: lapho ufaka umnyombo noma uvala ibhokisi, kufakwa ngenkani, kubangela ukonakala kwasendaweni noma ukuqhekeka kwesisekelo sesangelo ngenxa yokucindezela. Ukubeka i-PIN / GROOVE usayizi ukuphambuka noma ukugqoka: Isizinda sesihlabathi asikwazi ukubeka kahle noma ukunyakazisa ngesikhathi sokusebenza. Ukusebenza okungafanele okuyisisekelo okuyisisekelo Ukusebenza okungafanele kokuvalwa kwebhokisi: Ukucindezela ngokweqile nokungazinzile ngesikhathi sokuvalwa kwebhokisi kungadala ukuthuthwa okuyingxenye noma okuphelele, ukonakala, noma ukuqhekeka kwesisekelo sasemhlaba esihlanganisiwe. Umthelela we-Metal Liquid: Ngesikhathi sokuthulula, ukugeleza okusheshayo kwensimbi okusheshayo kunomthelela ngqo ezingxenyeni ezibuthakathaka zesisekelo sesanti (njengekhanda eliyisisekelo noma ingxenye ethile Idizayini engenangqondo yohlelo lokuthulula (onjenge-Direct Sand Core) izokhulisa le nkinga. Ukuphakamisa ibhokisi (umlilo) Ngalesi sikhathi, umnyombo wesihlabathi angakwazi ukuntanta noma ukuhambisa wonke, okuholela ekukhuphukeni ngosayizi wokuphonsa noma ukubukeka okuhle. Yize lokhu kungushintsho kuyo yonke imithambo, izici zesikhundla se-sand core zizokhululwa ngokwengeziwe.

2. Ukunwetshwa kwe-Thermal kwesihlabathi Lapho i-liquid yensimbi ephezulu kakhulu ixhumana ingaphezulu kwesisekelo sesihlabathi, isihlabathi esingaphezulu sisheshe sifudumala futhi sihlose "igobolondo" elinzima "), ngenkathi isihlabathi esinzima"), ngenkathi isihlabathi esiyisisekelo sishisa kancane futhi siyaqhubeka ukunwebeka kancane futhi siyaqhubeka ukunwebeka. Leli bhanyethi elinzima livimbela ukwanda kwangaphakathi, okwenza ukuthi amandla okwanga kwangaphakathi akhishwe ngaphandle. Lokhu kungahle kuholele ekucindezelweni kwangaphandle kwesihlabathi sokubumba: Uma isihlabathi sokubumba (isihlabathi se-resin) sizungeze umnyombo wesihlabathi futhi ukukhiqizwa okuphezulu kokushisa okuphezulu kodwa ukunwebeka kwesisekelo sendawo kuzocindezela ukuqondisa komgwaqo ophonsa, okwenza ukuba usayizi we-cavity unciphise. Kepha ezimweni ezithile (ezifana nokuvumelanisa, isakhiwo esiyinkimbinkimbi, kanye nokuvinjelwa kwasendaweni), kungabonakala futhi njengokuhlanekezela noma ukuqubuka kwendawo okuyisisekelo, kuholela ekunciphiseni okumnandi. Ukuncipha kokuncipha ngaphakathi (ukucaciswa okujwayelekile): Lapho umnyombo wesihlabathi uzungezwe ngokuphelele yi-molten Metal, amandla okwakha azoncipha aqine ngokuphelele aqonde esimweni esithi "usayizi wokuphonsa '(usayizi we-cavity ube mncane). Lokhu kuphambene nalokho okuphambene nokuzuzisa. Ukunwetshwa okwedlulele okuholela ekuqhekekeni noma ekuchithekeni (okungahle kube nomphumela othokomele) ama-protor amnandi. Ukushisa ngokweqile kokushisa okuthe xaxa: izinga lokushisa ngokweqile elithela ngokweqile likhulisa into yokunwebeka ye-thermal yesihlabathi se-sand. Ithonya lenqubo yokupholisa: Ngemuva kokuqina kwensimbi kuqina futhi kuncipha, ukuwa kwesihlabathi okuyisisekelo. Uma umnyombo wesihlabathi unwebeka futhi uwa kahle noma ngokungalingani ngesikhathi senqubo yokupholisa, kungathinta futhi ukwakheka kokugcina kokuphonsa.

I-3. Izinto zangaphandle noma ukuhlangana okuphezulu egumbini eliphakeme e-cavity: amabhlokhi esihlabathi asakazekile noma imfucumfucu: Ngesikhathi sokufakelwa kwesihlabathi, noma imfucumfucu yangakini, ekugcineni ungena emgodini ngaphambi kokuvalwa kwensimbi, kwakha ama-sumpunce. Ukuqongelelwa kwe-coaging noma ukuncipha: Ukuqongelelwa kwe-Local Coang Confinition esihlabathini noma i-cavity kukhulu kakhulu noma kuyawa kuma-patches, kuhlala isikhala kanye nokwakha ama-sumpunce. Ukungalingani kokungalingani kwesihlabathi sokubumba: ngesikhathi sokubumba, kunokuhlangana ngokweqile ezindaweni ezithile (yize umsebenzi we-resin wakheka ngokuqina, okuholela ekutheni kube nokunwebeka ngokweqile kwale ndawo ngaphansi kwengcindezi yokushisa noma yensimbi, kubangela ukuthuthuka kwendawo, kubangele ukuncipha kwengcindezi.

2, Ungaxazulula Kanjani Ukuxazulula Futhi Ukuxazulula:

1 Ukwakheka kwama-protor amnandi (ingabe ama-protors ejwayelekile, ama-burrs, noma ama-bulger arregur?)

2. Bheka isizinda se-sand: Ukulinganisa kukasayizi Bheka noma yiziphi izimpawu zokukhubazeka noma ukushayisana. Ukuhlolwa okubukwayo: Bheka ingaphezulu ukuze kube nemifantu, ukulangazelela, nokuxoshwa. Amandla wokuhlola we-Fracture (yi-Crispy yesikhungo?). Ukulandelela kwenqubo yokulapha

3. Bheka i-Core Head kanye nomnikazi oyisisekelo: ukukala usayizi wekhanda eliyinhloko lebhokisi eliyisisekelo kanye nosayizi womgogodla wemodeli eyisisekelo yemodeli eyisisekelo, bese ubheka ukuthi igebe linengqondo yini futhi livumelana yini. Bheka usayizi nokugqoka kwe-PIN / GROOVE.

4. Bheka inqubo yokusebenza: Bheka ukuthi ngabe ukusebenza okuyisisekelo nokuvalwa kwebhokisi kuyamiswa futhi kuzinzile? Ingabe kukhona ukushayisana noma into enzima yokuncipha? Bheka ukuthi isisindo nokuqinisa i-iron yengcindezi / ukulungiswa kwanele futhi kunokwethenjelwa? Inqubo yokuthela bushelelezi? Ingabe insimbi encibilikisiwe igeleza ngqo esigodini sesihlabathi?

5. Bheka amapharamitha wezinto ezibonakalayo kanye nenqubo: Ifilimu elihlanganisiwe lesihlabathi: Bheka i-batch, isikhathi sokubeka, nokuthi ngabe kukhona izigaxa ezimanzi? Uma kunesidingo, vivinya amandla ayo ashisayo namandla ashubile. Ukuthela izinga lokushisa: Ngabe liphezulu kakhulu? Zama ukunciphisa ngokufanele (ngokuya ngezinto ezibonakalayo) ngenkathi kuqinisekisa ukufakwa kwemali. I-Sand Core Design: Hlaziya ukuthi usayizi wekhanda eliyinhloko, ukusetshenziswa kwesihlabathi, kanye nelungiselelo lokuqinisa anengqondo? Ngabe ucabangele izici zokunwebeka ezishisayo zesihlabathi esihlanganisiwe? Ukukhuphula inquboxhaka inqubo (inani le-anti deformation) ezindaweni ezibalulekile. Uhlelo Lokuthelula: Gwema ukuvumelanisa i-Sproe ngqo ngezindawo ezibuthakathaka zesisekelo sesihlabathi. Ukuphelelwa amandla: Qinisekisa ukuqeda amandla abushelelezi kwesizinda se-sand ukugwema ukuqhekeka kwegesi okungadala ukucindezela kwensimbi yendawo kube phezulu kakhulu futhi kucindezele umnyombo wesihlabathi.

I-6. Ukuhlaziywa kokumbumbuluzwa: Lapho izimo zivumela, sebenzisa isoftware yokulingisa ukuze ihlaziye inqubo yokugcwalisa kanye nokuqina kwensimbi encibilikisiwe, qaphela i-deformation, ukuhanjiswa, kanye nengcindezi yesisekelo sesihlabathi.

Isifinyezo samaphoyinti asemqoka: Isici esisolwa ngokusolwa ngamaphutha amnandi adangele ama-cores esihlabathi ahlanganisiwe yizonakaliso noma ukuhanjiswa kwesihlabathi ngesikhathi sokukhiqiza, ukusebenza (ukuvalwa kwebhokisi lokufaka), kanye nokuthela izinqubo. Amandla anganele, izingqinamba zegebe eliyisisekelo, ukushayisana okusebenzayo, umthelela wensimbi, kanye nomthelela we-batal liquiding okubangelwa ukuqina okumpofu (ngaphansi kwezizathu eziqondile) ezijwayelekile. Inkinga yokunwebeka eyingqayizivele ye-laminated sand ingaholela ekunciphiseni okunganele komgodi wangaphakathi (ukwanda kokuphonsa kodonga noma ukwehla komthambo wangaphakathi), kodwa kuvuselelwa kanzima (njengokuqhekeka kwesihlabathi), kungahle kuboniswe ngokuqondile noma ngokuqondile ngokuqondile noma okubonakalayo ngokuqondile noma okubonakalayo ngokuqondile. Ukuphenya ngokuhleleka / izici zokufuduka (amandla, imvume, ukusebenza, ukuphakamisa) kuvame ukuba yinkomba yokuxazulula izinkinga.
