Xa usiva 'i-silicon mold casting', ingqondo ihlala itsibela ngqo kwi-trinkets encinci ye-resin okanye i-hobbyist prototypes. Yinto eqhelekileyo leyo, kwaye ngokuphandle iyasilela, ukungaqondi kakuhle. Kwimeko yoshishino, ngakumbi xa ujongene neejometri ezintsonkothileyo zamalungu esinyithi asebenzayo, indima ye-silicone-qaphela i-'e', imathiriyeli yebakala leshishini-ibaluleke kakhulu. Ayisosiphelo semveliso kodwa sisixhobo esibalulekileyo, esisoloko sixoxwa ngaphantsi, isixhobo somlamli. Amava am ajikeleza zombini isiseko esichanekileyo kunye nevenkile yomatshini, kwaye ndibone iiprojekthi ezininzi zikhubeka ngokuphatha inkqubo yokwenza umngundo njengento ecingelwayo. Inyani kukuba, umgangatho we-silicone ngundo wakho uchaza ngokuthe ngqo umgangatho wepateni ye-wax, ethi ichaze ukuphosa kwentsimbi yokugqibela. Yenza inyathelo lokuqala lingalunganga, kwaye usenza nje izinto ezilahliweyo.
Ibhulorho yeSilicone: Ukusuka kwiModeli ye-3D ukuya kwiPatheni yeWax
Masithethe inkqubo. Asazi isinyithi ngqo abicah. Ngumahluko obalulekileyo lowo. Kwi-investment casting, eyona shishini lethu elingundoqo Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), i-silicone mold isetyenziselwa kuphela ukuvelisa iipateni ze-wax. Ulandelelwano luyi: imodeli eyinkosi (ihlala i-3D eprintiweyo okanye yomatshini) -> i-silicone mold -> isitofu se-wax etyhidiweyo -> i-wax pattern assembly -> isakhiwo seqokobhe le-ceramic -> ukuchithwa -> ukugalelwa kwesinyithi. I-silicone mold yi-replicator. Ukuchaneka kwayo, ukugqitywa komphezulu, kunye nokuqina kwayo kuqinisekisa ukuba iipateni zakho ze-wax zithembeke kangakanani kuyilo lwangaphambili. Ndichithe iiyure ezininzi ndixoxa ngobulukhuni baseNxwemeni nababoneleli ngezinto eziphathekayo-i-20A ethambileyo inokubamba iinkcukacha ezimangalisayo kodwa iphele emva kokudutyulwa okungama-50, ngelixa i-40A inokuhlala kuma-300 kodwa umngcipheko wokukrazula kwi-undercuts ezinzulu. Akukho mpendulo yendalo yonke, kuphela uthotho lwezorhwebo olusekwe kwinxalenye yejometri kunye nomthamo.
Enye intloko ebuhlungu kukubanjwa komoya. Xa ugalela i-silicone phezu kwenkosi entsonkothileyo eneepokotho ezinzulu okanye izinto ezintle, amaqamza omoya alutshaba. Sizame onke amaqhinga: iimbiza zoxinzelelo, amagumbi okucoca i-vacuum, kunye nokubrasha ngobunono umaleko obhityileyo we-silicone kwimodeli kuqala. Indlela ethe ekugqibeleni yacofa uthotho lweeprototypes ze-impeller ibandakanya ukugalelwa kwamacandelo amabini kunye netafile ethambekileyo eyakhiwe ngokwesiko. Yayiyinkqubo emdaka, ephindaphindayo, kodwa iye yafumana ukubalwa kweqamza ukuya kutsho ku-zero. Olo luhlobo lwezandla ekusombululeni ingxaki ongayi kuyifumana kwincwadi yesifundo. Uyakwazi ukubona ezinye zeziphumo ezintsonkothileyo zeli nqanaba lokwenza ipateni kwisifundo sophando kwindawo yethu https://www.tsingtaocnc.com.
Ukukhethwa kwe-silicone ngokwayo isayensi. Sisebenzisa kakhulu iisistim zokunyanga iplatinam ukushwabana kwazo okuphantsi kunye nokuveliswa kwakhona okugqwesileyo kweenkcukacha, ngakumbi ezibaluleke kakhulu kwiindawo eziya kuthi kamva zifakwe intsimbi engenasici okanye ialloys esekwe nickel. I-tin-cure inexabiso eliphantsi, kodwa imiba yothintelo kunye nokushwabana okuphezulu kunokwazisa ukutenxa okuye kwanda kwinxalenye yokugqibela yentsimbi. Ngomsebenzi onomthamo ophezulu wecandelo lehydraulic kulo nyaka uphelileyo, siye salingisa ngazo zombini. Iplatinam-cure mold ivelise iipateni zewax ezibamba ukunyamezela ±0.1mm, ngelixa ibhetshi yetin-cure iye yakhukuliseka. Ixabiso langaphambili laliphezulu, kodwa ligcine intywenka yemali ngexesha lomatshini osezantsi ukulungisa iimpazamo.
Apho i-Mold idibana neNsimbi: Ukuhamba komsebenzi we-QSY
Imbali yethu yeminyaka engama-30 ekusaseni nasematshinini ayiphelelanga nje ngokuba noomatshini; imalunga nokuphuhlisa inkqubo eqhagamshelweyo. I i-silicon mold casting inkqubo yeepateni kukuzola, ukucoceka kwegumbi umanduleli wenyaniso enengxolo, evuthayo yesiseko. Ipateni ye-wax eyenziwe kwi-silicone mold egqibeleleyo iya kuba nesiphelo esiphezulu esiguqulela ngokuthe ngqo kwigobolondo ye-ceramic. Ipateni erhabaxa, enemingxuma ukusuka kumngundo ombi ithetha ukuba uqala inkqubo yeqokobhe ngendlela engalunganga, ekholisa ukukhokelela emithanjeni okanye ekudibaneni kokusalwa kokugqibela. Sifunde ukuhlola iipatheni ze-wax ngokuhlolisisa okufanayo njengenxalenye yokugqibela yomatshini.
Apha kulapho udibaniso kunye nomatshini we-CNC luba lungenangxoxo. Nokuba kunotyalo-mali olugqibeleleyo, uninzi lwamalungu asebenzayo afuna ukuchaneka komphezulu wokukhwelana, imisonto, okanye iibhore ezinyamezelayo. Umzimba wevalvu esisandula ukuvelisa umthengi ngumzekelo obalaseleyo. Ipatheni ye-wax eyenziwe nge-silicone yakha iipaseji eziyinkimbinkimbi zangaphakathi ezingenakukwazi ukwenza umatshini. Emva kokuphoswa kwentsimbi ephindwe kabini, isebe lethu le-CNC lathatha indawo, lilungisa ubuso be-flange kunye nezihlalo zevalve ukuya ku-Ra 0.8. I i-silicon mold ijometri yenziwe yasebenza; Umatshini we-CNC waqinisekisa ukusebenza. Inkqubo enye ithobela enye; kufuneka basebenze kunye.
Ukungaphumeleli ngutitshala ongcono kunokuphumelela. Kwangoko, sasineprojekthi yothotho lwesakhelo se-cobalt-chrome alloy yamazinyo. Ijometri yayibaxekile, inencasa-encinci imida. Indlela yethu yokuqala ye-silicone yokubumba isebenzise uyilo oluqhelekileyo lokubumba ibhloko. Isiphumo? Iipateni zewax ezihlala ziqhekeka ngexesha lokubunjwa. Isisombululo sasingeyona i-silicone engcono, kodwa i-mold design eyahlukileyo-inxalenye eninzi, i-mold keyed ekhulula ngononophelo uxinzelelo ngexesha lokukhutshwa kwe-wax. Yongeza usuku kwinkqubo yezixhobo kodwa yaphelisa i-100% yeelahleko zepatheni. Eso sifundo siyitshintshe ngokusisiseko indlela esijongana ngayo noyilo lokungunda kwiimpawu ezibuthathaka.
Imiba yeMathiriyeli: Ngakumbi kunentsimbi kunye neNtsimbi nje
Ngelixa siphatha okuninzi intsimbi kunye nentsimbi yekhabhoni, iimfuno ze i-silicon mold casting kuba iipateni ziba baluleke ngakumbi ngealloyi ezikhethekileyo. Xa ujongana nezinto ezibizayo ezifana ne-nickel-based superalloys ye-aerospace okanye i-cobalt alloys ephezulu yokunxiba kwishishini lokutya, iindleko zokulahlwa okulahliwe ayisiyiyo nje isinyithi-lixesha elilahlekileyo kunye neshedyuli yemveliso eyaphukileyo. Ukuzinza komda kwe-silicone ukungunda kwakho kubaluleke kakhulu kuba ezi ngxubevange zihlala zineendawo eziphezulu zokunyibilika kunye neendlela ezahlukeneyo zokuziphatha eziqinileyo, ezinokukhulisa nakuphi na ukungafezeki okuncinci ukusuka kwinqanaba le-wax.
Ndikhumbula iprototype ebaleka iblade ye-inconel. Abadlali abambalwa bokuqala babonise ukukhukuliseka okuncinci kwiprofayili ye-airfoil. Asiyilandeli ngasemva hayi kwiqokobhe le-ceramic okanye ukugalela, kodwa ukuya kulwandiso lwe-thermal olungenakulinganiswa kubumba lwe-silicone ngexesha lenqanaba lokutofa kwewax yoxinzelelo oluphezulu. Umngundo ngokwawo wawugqwetha phantsi kweemeko zemveliso, into engazange ibonakale kuvavanyo olugalelwe ngesandla. Kwafuneka sitshintshele kwi-high-temperature-stability silicone formulation kunye nokuguqula i-curve ye-wax injection pressure curve. Yayilunxibelelwano oluchuliweyo, olunexabiso elikhulu phakathi kwemathiriyeli oyifundayo ngokuphindaphinda kabuhlungu.
Into ethathwayo apha kukuba ukucacisa i-silicone yokubumba ayicacanga ngokungenathemba. Kufuneka ucinge ngokubhekiselele kulo lonke ikhonkco: i-injection ye-wax ye-injection kunye ne-shrinkage, ukushisa kwe-alloy yokuthulula, kunye nokunyamezela kokugqibela okufunekayo. Isixhobo sokubumba ngumthathi-nxaxheba osebenzayo kwinkqubo, hayi isikhongozeli sokwenziwa.
Imigibe eSebenzayo kunye neenkcukacha ezingathethwayo
Ngaphandle kwamaphepha edatha, kukho iinyani zomgangatho wevenkile. I-Silicone inobomi bembiza, kwaye ukudibanisa iibhetshi ezinkulu zokungunda okukhulu lugqatso oluchasene nexesha. Ndibe yinxalenye yeqela elithulula ngokungxama njengoko izinto zaziqala ukujiya, ndisazi ukuba ukugalelwa ngokukhawuleza kunokuthetha ibhloko engenaxabiso yerabha. Ukukhupha umoya kolunye uhlobo lobugcisa. Uzibeka phi iivents ukuvumela umoya ukuba uphume ngaphandle kokwenza ukukhanya kwipateni yewax? Sihlala songeza imingxuma yodongwe yethutyana ngexesha lokugalela abicah, emva koko sigrumbe kamva ukwenza amajelo afanelekileyo. Yinto manual, phantse sculptural isakhono.
Emva koko kukho isondlo. Isikhunta esihle se-silicone sinokuvelisa amakhulu eepateni ze-wax, kodwa zithobisa. Ifunxa ukufuma okuvela emoyeni, isabela kancinane kunye nezithako ezithile zewax, kwaye ngoomatshini iyadinwa. Sinenkqubo yokungena kwi-molds yethu-isibalo sokudubula, iziphumo zokuhlola okubonakalayo, kunye nemilinganiselo elinganisiweyo yesampuli ye-wax yesampula yonke imijikelezo ye-50. Le datha isenza siqikelele ubomi bokungunda kunye neshedyuli yokulungiswa kwezixhobo phambi kokuba umgangatho wehle. Olu qeqesho lusebenzayo lulo olwahlula ivenkile yemisebenzi kumthengisi othembekileyo ofana ne-QSY.
Okokugqibela, musa ukukujongela phantsi ukubaluleka kwemodeli eyinkosi. Ukuba inkosi yakho eprintiweyo ye-3D inemigca yomaleko, ukungunda kwakho kwe-silicone kuya kuyibamba, kwaye ipateni yakho ye-wax iya kuba nayo, kwaye iqokobhe lakho le-ceramic liya kuba nalo, kwaye ukuphosa kwakho kwentsimbi yokugqibela kuya kuba nakho. Ngamanye amaxesha, kuyabiza kakhulu ukusebenzela umatshini we-aluminiyam ye-aluminiyam yokungunda kwe-abicah yevolumu ephezulu, ukufumana nje loo ndawo yokuqalisa egudileyo. Luhlalutyo oluqhelekileyo lweendleko-inzuzo eyenzekayo ekuqaleni kwayo yonke iprojekthi.
Ukuqukumbela: Sisixhobo, hayi iBullet yomlingo
Ngoko, ukugqiba oku, i-silicon mold casting kumxholo wecandelo lemveliso yentsimbi yeshishini linyathelo elintsonkothileyo, elijonge iinkcukacha kuhambo olude.
