1. Ingcindezi eyinsalela iphezulu kakhulu
Emsebenzini wenqubo, kuyindlela elula yokunciphisa ukucindezeleka okusele ngokunciphisa ingcindezi yomjovo, ngoba ukucindezela komjovo kuhambisana nengcindezi esele.
Uma imifantu ebusweni bezingxenye zepulasitiki imnyama nxazonke, kubonisa ukuthi ingcindezi yomjovo iphezulu kakhulu noma inani lokuphakela lincane kakhulu. Umfutho womjovo kufanele wehliswe ngendlela efanele noma inani lokudla lenyuswe. Lapho ukwakhiwa ngaphansi kwesimo sokushisa okuphansi kwempahla kanye nokushisa kwesikhunta, ukuze wenze i-cavity igcwale, kuyadingeka ukusebenzisa ingcindezi ephezulu yomjovo, okuholela ekucindezelekeni okukhulu okusala ezingxenyeni zepulasitiki.
Kuze kube manje, izinga lokushisa le-cylinder kanye nesikhunta kufanele linyuswe ngendlela efanele, umehluko wokushisa phakathi kwezinto ezincibilikisiwe kanye nesikhunta kufanele uncishiswe, isikhathi sokupholisa kanye nesivinini sombungu wesikhunta kufanele kulawulwe, ukuze ukuqondisa kombungu. iketango lamangqamuzana linesikhathi eside sokululama.
Ngaphezu kwalokho, ngaphansi kwesisekelo sokuqinisekisa ukungondleki okwanele futhi ungenzi izingxenye zepulasitiki zinciphise futhi zigweme, isikhathi sokubamba ingcindezi singafinyezwa ngokufanelekile, ngoba isikhathi sokubamba ingcindezi side kakhulu futhi kulula ukukhiqiza ukucindezeleka okusalayo ukuze kubangele imifantu.
Ekwakhiweni kwesikhunta nokukhiqizwa, isango eliqondile elinokulahlekelwa kwengcindezi encane kanye nokucindezela komjovo ophezulu kungasetshenziswa. Isango eliya phambili lingashintshwa libe yisango lezinaliti eziningi noma isango elihlangothini, futhi ububanzi besango bungancishiswa. Lapho uklama isango elihlangothini, isango le-flange elingasusa ingxenye ephukile ngemva kokwenza ingasetshenziswa.
2. Amandla angaphandle abangela ukugxila kwengcindezi esele
Ngaphambi kokukhishwa kwezingxenye zepulasitiki, uma indawo ephambanayo yendlela yokukhipha incane kakhulu noma inombolo ye-ejection rod inganele, indawo yenduku yokukhipha ayifaneleki noma ukutsheka kokufakwayo, ibhalansi engalungile, ukuthambeka kokukhishwa kwe-ejection. isikhunta ayanele, ukumelana ne-ejection kukhulu kakhulu, kuzoholela ekugxilweni kokucindezeleka ngenxa yamandla angaphandle, ukuze ubuso bezingxenye zepulasitiki buqhekeke futhi buqhume.
Ngaphansi kwezimo ezijwayelekile, lolu hlobo lokwehluleka luhlala lwenzeka eduze kwenduku ye-ejector. Ngemuva kwalolu hlobo lokwehluleka, kufanele uhlole ngokucophelela futhi ulungise idivayisi yokukhipha. Induku ye-ejector ihlelwe engxenyeni yokumelana ne-demulding, njengokuphuma, imigoqo yokuqinisa, njll. Uma inani lezintambo ze-jacking lingakwazi ukunwetshwa ngenxa yendawo elinganiselwe ye-jacking, indlela yokusebenzisa indawo encane kanye nezinduku eziningi ze-jacking. ingamukelwa.
3. Ukufakwa kwensimbi kubangela ukuqhekeka
I-thermal expansion coefficient ye-thermoplastic inkulu ngokuphindwe ka-9~11 kunensimbi kanye nezikhathi ezi-6 ezinkulu kune-aluminium. Ngakho-ke, ukufakwa kwensimbi ezingxenyeni zepulasitiki kuzovimbela ukuncipha okuphelele kwezingxenye zepulasitiki, okuholela ekucindezelekeni okukhulu, futhi inani elikhulu lokucindezeleka okusalayo lizoqoqana eduze nokufakwa ukuze kubangele imifantu ebusweni bezingxenye zepulasitiki. Ngale ndlela, ukufakwa kwensimbi kufanele kufakwe ngaphambili, ikakhulukazi lapho ukuqhekeka ebusweni bezingxenye zepulasitiki kwenzeka ekuqaleni komshini, iningi lawo elibangelwa ukushisa okuphansi kokufakwayo.
Ekukhetheni izinto zokusetshenziswa zokubumba, kufanele futhi kusetshenziswe i-resin ephezulu yesisindo samangqamuzana ngangokunokwenzeka, uma kufanele kusetshenziswe izinto ezingavuthiwe zokubumba isisindo samangqamuzana, ukujiya kwepulasitiki okuzungeze okufakiwe kufanele kuklanywe kushubile, kwe-polyethylene, i-polycarbonate, i-polyamide, i-cellulose acetate. ipulasitiki, ukujiya kwepulasitiki okuzungeze okufakwayo kufanele kulingane okungenani nengxenye yobubanzi bokufaka; Nge-polystyrene, ukufakwa kwensimbi ngokuvamile akufanelekile.
4. Ukukhetha okungalungile noma ukungcola kwezinto ezingavuthiwe
Ukuzwela kwezinto zokusetshenziswa ezihlukene ekucindezelekeni okuyinsalela kuhlukile. Ngokuvamile, i-non-crystalline resin ijwayele ukuqhekeka ngenxa yengcindezi eyinsalela kune-crystalline resin. Ku-resin emuncayo kanye ne-resin exutshwe nezinto ezigaywe kabusha kakhulu, ngenxa yokuthi inhlaka emuncayo izobola futhi ibe embrittleness ngemva kokushisa, ingcindezi encane eyinsalela izobangela ukuqhekeka okuncane, futhi inhlaka enokuqukethwe okuphezulu okugaywe kabusha inokungcola okwengeziwe, okuqukethwe okuguquguqukayo okuphezulu, okuphansi. amandla impahla, futhi kulula ukukhiqiza ukucindezeleka ngokuqhekeka. Ukuzijwayeza kubonisa ukuthi i-viscosity ephansi ye-resin evulekile akulula ukuphahlazeka, ngakho-ke inqubo yokukhiqiza, kufanele ihlanganiswe nesimo esithile sokukhetha izinto zokwakha ezifanele.
Enqubweni yokusebenza, i-ejenti yokukhulula yezinto ezincibilikisiwe nayo ingumzimba wangaphandle, njengokuthi umthamo ongalungile uzophinde ubangele imifantu, kufanele uzame ukunciphisa umthamo wayo.
Ngaphezu kwalokho, lapho umshini womjovo wepulasitiki udinga ukufaka esikhundleni sezinhlobonhlobo zezinto ezingavuthiwe ngenxa yokukhiqizwa, kufanele uhlanze izinto ezisele kusiphakeli se-hopper nokomisa, futhi usule izinto ezisele kusilinda.
5. Ukwakheka okungekuhle kwezingxenye zepulasitiki
Amakhona abukhali kanye nezikhala ezakhiweni zezingxenye zepulasitiki cishe zizokhiqiza ukugxila kokucindezeleka, okuholela ekuqhekekeni nokuqhekeka ebusweni bezingxenye zepulasitiki. Ngakho-ke, i-Angle yangaphandle kanye ne-Angle yangaphakathi yesakhiwo sepulasitiki kufanele yenziwe nge-radius enkulu ngangokunokwenzeka. Imiphumela yokuhlola ibonisa ukuthi isilinganiso phakathi kwe-radius ye-arc nokuqina kodonga lwekhona ngu-1:1.7. Lapho uklama ukwakheka kwezingxenye zepulasitiki, izingxenye okufanele zenziwe zibe amakhona acijile nemiphetho ebukhali kufanele zisasebenza zibe i-arc encane ene-radius encane yoguquko engu-0.5mm, enganweba impilo yokufa.
6. Kukhona ukuqhekeka esibunjeni
Enkambweni yokubunjwa komjovo, ngenxa yokucindezela okuphindaphindiwe komjovo wesikhunta, ingxenye enqenqemeni ye-cavity ene-Angle ebukhali izoveza imifantu yokukhathala, ikakhulukazi eduze kwembobo yokupholisa kulula kakhulu ukukhiqiza imifantu. Lapho isikhunta sithintana nombhobho, phansi kwesikhunta kuyacindezelwa. Uma imbobo yendandatho yokumisa yesikhunta inkulu noma udonga olungezansi luncane, ingaphezulu lesikhunta lizoveza imifantu yokukhathala.
Lapho imifantu ebusweni bomgodi wokubumba ibonakala ebusweni bengxenye yepulasitiki, imifantu ebusweni bengxenye yepulasitiki ihlale ibonakala ngokuqhubekayo ngendlela efanayo engxenyeni efanayo. Lapho kuvela imifantu enjalo, indawo ehambisanayo yomgodi kufanele ihlolwe ngokushesha ukuze kutholakale imifantu efanayo. Uma ukuqhekeka kungenxa yokucabangela, isikhunta kufanele silungiswe ngomshini.
