Ekubunjweni e abicah isikhunta: imishini. I cleaner ekubunjweni isikhunta of abicah

Ukuze womshini esincane preforms plastic ngokuvamile isetshenziselwa cleaner ebeka abicah isikhunta. Le ndlela kuqhathaniswa ukonga (Ekhiqizako isikhunta metal ifuna imali ethé xaxa emikhulu kokubili isikhathi nemali). Ngaphezu kwalokho, isikhunta abicah zisetshenziswa ngokuphindaphindiwe, futhi kwehlisa izindleko zokukhiqiza.

umqolo plastic

Ingqikithi inqubo ukulahlwa amapulasitiki kanje. Indaba oncibilikisiwe e screw iyunithi (imishini ekhethekile ukusakaza e abicah isikhunta). Ngaphansi kwethonya nenqwaba uhamba piston eduze umgijimi, bese ugcwalisa isikhala isikhunta. Ngakho ungathola ekusakazeni. Lapho ukufuthelana, ama-athomu plastic zazo liqukethe, aqale ukuhambisa ngezikhathi futhi ngobudlabha. Nokho izinhlamvu ziqala ukwakheka phezu ukupholisa crystallization izikhungo. Ngezinye ezindongeni crystal isikhunta ukukhula kwembewu kwenzeka, kulandelwa inqubo kwenzeka ngaphakathi ekusakazeni. Kulesi sigaba kubalulekile kakhulu uqaphele le mibandela lokushisa, ukukhetha lesifanele ukuchayeka isikhathi. Ngamanye amapulasitiki udini abicah isikhunta kuyoba eliphansi, nge iminonjana ebonakalayo ngomshado. Kodwa ngaphezu kwakho konke, kufanele senze amafomu ngokwabo, futhi lapho mass kuyothululwa ngoba crystallization.

ukudala amafomu ukulingiswa ubuchwepheshe

Kunezindlela eziningana ukudala abicah isikhunta. Eyokuqala of them - Ukusakaza okuqinile. Le ndlela kufanelekile imiklamo elula: imifanekiso, ukukhiqizwa isikhumbuzo, izingxenye ezimbili ntathu. Imodeli ibekwe ku isikhunta, egcwele abicah. amafomu Releasable zenziwa njengalena langaphambilini, isetshenziselwa ngaphezulu bobunjwa eziyinkimbinkimbi. Two-ingxenye isikhunta ekhiqizwa in izigaba eziningana. Okokuqala, engxenyeni yokuqala ka ingenalutho ugcwele, ngemva kokuphulukisa abicah nabokhulumile ifomu bese ingxenye yesibili wenza ngokufanayo. Kubaluleke kakhulu okwamanje ekhethwe indlela esekelwe sivala ekhethekile (ukubumba ifomu abicah yalolu hlobo kufanele kwenzeke ngaphandle ukufuduka yayo). I esicishe kulandela yonke imininingwane efomini blank "ku lisakazeka." On the ucezu nge ibhulashi ukusebenzisa abicah sasivumela viscous. Inqubo yenzeka ngezigaba eziningana, kubalulekile ukuba ukuphindaphinda ephelele ezicashile elincane umkhiqizo. Kulokhu, ifomu ngokwawo ngempela nomzimba omncane - 3mm. Ukuthi ibibambe kwefomu esigabeni sokugcina kudala yangaphandle igobolondo kanzima.

Silicones ngokwenza isikhunta

Umshini thusi e abicah isikhunta kuhilela ukusetshenziswa ngezinto ezahlukene ukudala matrices. Omunye wabo - ezifana abicah Isikhunta Star. Isetshenziselwa yokugcwalisa eliqinile kancane kancane, namandla ngokwanele futhi nivumelane nezimo. Ukuphulukiswa senzeka emazingeni okushisa okuvamile. Ukuze amasu "e lisakazeka" ngokuvamile zisebenzisa uchungechunge Rebount. Lokhu abicah has a viscosity okusezingeni eliphezulu, futhi lapho zingalawulwa nge thickener. Ekubunjweni e abicah isikhunta yalolu hlobo kwenza kube nokwenzeka ukuba bathole eliphezulu, i-matrix okuqinile, futhi, ngokufanelekile, ephezulu ukucacisa imininingwane. Kukhona futhi silicones lulwimi lutho, okuyizinto ekahle yokuhlukanisa amafomu.

Izinto ukuze asakazwe

Njengoba umthetho, ngokuba yokukhiqiza izingxenye esetshenziswa ngokwabo polyurethane. Indaba ine amandla nomthelela omkhulu, ubulukhuni, kuyaqina. abafumana amandla eqine, izinyembezi ifa polyurethane zenjoloba. Ukusebenzisa kwabo ekwenzeni ezihlukahlukene bands, amasilinda, izitembu, gaskets, bushings. Futhi ngisho esetshenziselwa ukubumba ngepulasitiki okusobala. He is impela amelana UV imisebe futhi igcina obala yayo ngisho nalapho nokudweba. Ububanzi - .. lenses nokuvivinywa okuhlukahlukene, prototypes kwezokwelapha, yokukhiqiza aways, njll Ngokuvamile, ifomu abicah udini kuhilela ukusetshenziswa Izingxube ezimbili ingxenye, okuhlanganisa epulasitikini futhi ngokuqondile ekwandeni.

Ukusakaza epulasitiki abicah isikhunta. imishini

ukukhiqizwa yabadobi cast amalunga - kuyinqubo elikuvumela ukuba batch kwemifanekiso izingxenye yanoma yimuphi yinkimbinkimbi. Isikhathi esining impela, indlela ezisetshenziswa emasimini ukukhiqiza ukudla prototypes yahlolwa ngaphambi kokuqala zokukhiqiza serial, kwaqedwa ukubukeka design.

Industrial udini plastic ku imishini abicah isikhunta inikeza: ikamelo cleaner (umjovo udini umshini), kuhhavini, cleaner mixer (mixer). Silicone ekuqaleni okulungiselelwe ekamelweni cleaner, lapho impahla degassing inqubo. Lokhu kungenxa ukuvimbela ukwakheka Bubbles kwifomu. Uma ifomu lwenziwe ukuze asakazwe futhi osuke usushisa kakade, okuxubile ngokushesha polyurethanes (noma inhlaka ngokuba ingxenye yokugcina). Le nqubo kwenzeka ekamelweni cleaner. Inhlanganisela elachithwa ngokusebenzisa sprue ku isikhunta. Ukuze yokugcina ukucutshungulwa preform kudingekile ibekwe kuhhavini ekhethekile, lapho solidification yokugcina umkhiqizo ezingeni lokushisa 70 ° C.

Ikamelo cleaner. Izici Key

Ngokuvamile, ekukhiqizeni isikali usebenzisa asakazwe othomathikhi ku abicah isikhunta. Izinsiza kusebenza, okungukuthi egunjini cleaner, futhi ikuvumela ukuba ukulawula izinga lokushisa futhi usakaze isivinini. I-opharetha akudingi amakhono akhethekile ulwazi, njengoba isilawuli lisuselwa yesistimu yokusebenza, okuyinto has kokubili usuke othomathikhi futhi mathupha. Kukhona ithuba bese uhlela uhlelo ezikhethiwe. ukulungiswa abahlukahlukene emakamelweni preform ziyakwazi ukukhiqiza kufika ku-5 kg (isib ikhamera ST-02). Ukufakwa ifakwe ikheshi siphakamise abicah isikhunta. Kuyaphawuleka ukuthi uhlelo we ST-02 ingasetshenziswa njengendlela-matrix amancane ngempela ezisindayo.

Enye - MCP ikhamera. Imishini ukusakaza ku isikhunta abicah kwenza kube nokwenzeka ukukhiqiza izingxenye enezindonga ezacile nokuthinta ukumisa eziyinkimbinkimbi. Le nqubo kungenxa ingcindezi umehluko. Khona-ke, leli thusi okuholela luyasuswa, futhi ngemva kwalokho-ke osemanzi emoyeni. Umshini thusi e abicah isikhunta kwabanye izinhlobo amapulasitiki usuphothuliwe kuhhavini ukunikeza bafudumale umfaniswano emoyeni, futhi ngaleyo ndlela workpiece.

Final ukucutshungulwa yabalingisi amalunga

Ngemva mass plastic osemanzi ngokuphelele, kukhishwe ngokucophelela kusukela isikhunta. Kuvela machining ebusweni, kuthiwa uphunyukile ziboya isuswe kukhona phansi semfene. Uma preform efiswayo ingumuthi camera noma upende noma ezinye izinto zokuzivikela. Zigezwe futhi abicah isikhunta, asuse plastic ngokweqile. Khona-ke sagezwa, ukulungiselela ukusetshenziswa okwalandela. Kufanele kuqashelwe ukuthi plastic udini abicah isikhunta kuhilela ukusetshenziswa ngokuphindaphindiwe-matrices (izikhathi ezingu-20 kuya ku-80).

Izinzuzo esemqoka indlela

ukukhiqizwa yabadobi okhula ngamandla, kungaba qualitatively ukuhlola emakethe, ukuhlola imikhiqizo ukudala imisebenzi esiyingqayizivele wombhali e esincane. Silicone isikhunta ukuthi asetshenziswa umjovo udini, akuvumelekile ukukopisha ngokugcwele ukuthungwa, ijamo, umklamo preform. Umniningwane ezikhishwe kalula kusukela matrix, nakho kungasetshenziswa ngokuphindaphindiwe. Castings babe inombolo okungenani ebusweni ukukhubazeka, izakhiwo elikhulu ngokomzimba futhi lokukhanda. Ngaphezu kwalokho, kwezinye izimo, ngisho metal abicah isikhunta singase lichithwe.

Kodwa Inzuzo enkulu okuyinto ubeke abicah isikhunta - intengo. Abanikezeli isevisi ubonisa ukuthi izindleko yokugcina preform kuzoncika impahla plastic kanye izinto ngobuningi kusukela nemingcele (isib Usayizi nalutho 10 * 10 * 10 cm ungakwazi ikhiphe ruble 1500). Silicone ngokwayo angathengwa ruble 500 kilogram per, plastic - ruble 700. Izindleko metal isikhunta siphakeme ngokwanele ngezinye izikhathi ukuzisebenzisa nje ukuthi ayisizi (uma nokusakazwa amayunithi eziningana). A efanelekayo abicah matrix kanye lisetshenziswa ekhaya, ukuthenga izimpahla ezibizayo akudingekile. Umuntu kumelwe amane ukwenza isakhiwo zabo, acabangele esaphila polyurethanes (isikhathi lapho aqhubeke ewuketshezi futhi efanelekayo ethela), ukuhambisana nayo yonke ezicashile zobuchwepheshe - futhi ebeka abicah isikhunta okuthwala ngisho ekhaya. Ngokusho izibalo, izindleko preform esimweni samanje - ruble mayelana 70-140.
