Ukubunjwa komjovoIsango
Yisiteshi esixhuma umgijimi oyinhloko (noma umgijimi wegatsha) kanye nomgodi. Indawo ephambanayo yesiteshi ingalingana nesiteshi esikhulu sokugeleza (noma isiteshi segatsha), kepha imvamisa iyancishiswa. Ngakho iyindawo encane ephambanayo kulo lonke uhlelo lomgijimi. Ukuma nobukhulu besango kunethonya elikhulu kwikhwalithi yomkhiqizo.
Indima yesango yile:
A. Lawula isivinini sokugeleza kwezinto:
B. Ingavimbela ukugeleza emuva ngenxa yokuqiniswa ngaphambi kwesikhathi kokuncibilika okugcinwe kule ngxenye phakathi nomjovo:
C. Ukuncibilika okudlulayo kungaphansi kokugunda okuqinile ukuze kwandiswe izinga lokushisa, ngaleyo ndlela kuncipha ukubonakala kwe-viscosity futhi kuthuthukiswe ukugeleza kwamanzi:
D. Kulula ukuhlukanisa umkhiqizo kanye nohlelo lomgijimi. Ukuklama kwesango lokuma, ubukhulu kanye nesikhundla kuncike esimweni sepulasitiki, ubukhulu kanye nesakhiwo somkhiqizo.
Umumo Wesango Owehlukene:
Ngokuvamile, ukuma kwesango eliphambene nesango liyi-rectangular noma isiyingi, futhi indawo ye-cross-sectional kufanele ibe yincane futhi ubude kufanele bube bufushane. Lokhu akusekelwe kuphela emiphumeleni engenhla, kodwa futhi ngoba kulula ukuthi amasango amancane abe mkhulu, futhi kunzima ukuba amasango amakhulu anciphe. Indawo yesango kufanele ikhethwe ngokujwayelekile lapho umkhiqizo ushubile ngaphandle kokuphazamisa ukubukeka. Umklamo wesayizi wesango kufanele ucabangele izakhiwo ze-plastic melt.
I-Cavity iyisikhala esisesikhunjini sokubumba imikhiqizo yepulasitiki. Izingxenye ezisetshenziselwa ukwakha umgodi zibizwa ngokuhlanganyela njengezingxenye ezibunjiwe. Ingxenye ngayinye ebunjiwe ngokuvamile inegama elikhethekile. Izingxenye ezibunjiwe ezakha ukwakheka komkhiqizo zibizwa ngokuthi isikhunta se-concave (esibizwa nangokuthi isikhunta sesifazane), esakha isimo sangaphakathi somkhiqizo (njengezimbobo, izikhala, njll.) zibizwa ngokuthi ama-cores noma ama-punches (owaziwa nangokuthi isikhunta sabesilisa. ). Lapho uklama izingxenye ezibunjiwe, ukwakheka okuphelele kwesigxobo kufanele kuqala kunqunywe ngokuya ngezakhiwo zepulasitiki, i-geometry yomkhiqizo, ukubekezelelana kwe-dimensional kanye nezidingo zokusetshenziswa. Okwesibili ukukhetha indawo yokuhlukanisa, indawo yesango kanye nembobo yokukhipha umoya kanye nendlela yokudiliza ngokuvumelana nesakhiwo esinqunyiwe.
Ekugcineni, ngokuya ngobukhulu bomkhiqizo olawulayo, ukwakheka kwengxenye ngayinye kanye nenhlanganisela yengxenye ngayinye kunqunywa. I-plastic melt inengcindezi ephezulu lapho ingena emgodini, ngakho-ke izingxenye ezibunjiwe kufanele zikhethwe ngokufanele futhi zihlolwe amandla nokuqina. Ukuze kuqinisekiswe ingaphezulu elibushelelezi nelihle lemikhiqizo yepulasitiki kanye nokubhidlizwa kalula, ubulukhuni bobuso obuthinta ipulasitiki kufanele bube ngu-Ra>0.32um, futhi kufanele bukwazi ukumelana nokugqwala. Izingxenye ezakhiwe ngokuvamile ziphathwa ngokushisa ukuze kwandiswe ubulukhuni, futhi zenziwe ngensimbi engagqwali.
