Incazelo yolwazi oluyisisekelo mayelana nokubumba umjovo

Imishini yokubumba i-injection iyimishini ekhethekile yokwenza imikhiqizo yepulasitiki, esetshenziselwa ukukhiqiza izingxenye ezihlukahlukene zepulasitiki ezisetshenziswa zezimoto, zezokwelapha, zabathengi nezimboni.Ukubumba umjovo kuyindlela edumile ngenxa yezizathu ezinhlanu ezilandelayo:

1. Ikhono lokukhulisa umkhiqizo;

2. Zombili izimo ezilula neziyinkimbinkimbi zingenziwa;

3. Iphutha eliphansi kakhulu;

4. Izinhlobonhlobo zezinto ezingasetshenziswa;

5. Izindleko eziphansi zezinto ezingavuthiwe kanye nezindleko zabasebenzi.

Umshini wokubumba umjovo usebenzisa i-resin yepulasitiki nezibunjwa ukuze uqedele ukubumba komjovo.Umshini uhlukaniswe ikakhulukazi izingxenye ezimbili:

Idivaysi yokugoqa-gcina isikhunta sivaliwe ngaphansi kwengcindezi;

Idivayisi yomjovo- inhlaka yepulasitiki encibilika bese ugoqa ipulasitiki encibilikisiwe esikhunjeni.

Kunjalo, imishini iyatholakala futhi ngosayizi abahlukene, elungiselelwe ukukhiqiza izingxenye ezinobukhulu obuhlukahlukene, futhi ibonakala ngamandla okubamba umshini wokubumba umjovo ongawenza.

Isikhunta ngokuvamile senziwe nge-aluminium noma insimbi, kodwa ezinye izinto zingenzeka.Ihlukaniswe yaba izingxenye ezimbili, futhi ukuma kwayo kufakwe kahle ensimbi.Isikhunta singase sibe lula kakhulu futhi sishibhile, noma singase sibe yinkimbinkimbi kakhulu futhi sibize.Ubunkimbinkimbi buhambisana ngokuqondile nokucushwa kwengxenye kanye nenani lezingxenye kusikhunta ngasinye.

I-Thermoplastic resin isesimweni se-pellet futhi iwuhlobo lwezinto ezisetshenziswa kakhulu ekubumbeni umjovo.Kunezinhlobo eziningi zezinhlayiya ze-thermoplastic ezinohlu olubanzi lwezinto ezibonakalayo futhi ezifanele ukusetshenziswa kwemikhiqizo ehlukahlukene.I-Polypropylene, i-polycarbonate ne-polystyrene yizibonelo zama-resin asetshenziswa kakhulu.Ngaphezu kokukhethwa okubanzi kwezinto ezihlinzekwa yi-thermoplastics, nazo ziyakwazi ukuphinda zisetshenziswe, ziguquguquke futhi zincibilike kalula.

Inqubo yokubumba eyenziwa emshinini wokubumba umjovo inezinyathelo eziyisithupha eziyisisekelo:

1. Ukuhlanganisa-insimbi yokubopha yomshini icindezela izingxenye ezimbili zesikhunta ndawonye;

2. Umjovo-ipulasitiki encibilikisiwe evela engxenyeni yomjovo womshini ishaywa esikhunjini;

3. Ukugcinwa kwengcindezi-ipulasitiki encibilikisiwe efakwe esikhunjeni ingaphansi kwengcindezi yokuqinisekisa ukuthi zonke izindawo zengxenye zigcwele ipulasitiki;

4. Ukupholisa-vumela ipulasitiki eshisayo iphole ibe yinxenye yokugcina ngenkathi isesikhunjini;

5. Ukuvula isikhunta-idivayisi yokubopha yomshini ihlukanisa isikhunta futhi ihlukanise izingxenye ezimbili;

6. Ukukhipha-umkhiqizo oqediwe uyakhishwa esikhunjeni.

Ukubumba umjovo kuwubuchwepheshe obukhulu obungakhiqizwa ngobuningi.Kodwa-ke, iwusizo futhi kuma-prototypes ekwakhiweni komkhiqizo wokuqala noma ukuhlola kwabathengi noma komkhiqizo.Cishe zonke izingxenye zepulasitiki zingakhiqizwa ngokubunjwa komjovo, futhi izinkambu zayo zokufaka isicelo azinamkhawulo, zinikeza abakhiqizi indlela engabizi kakhulu yokukhiqiza izingxenye ezihlukahlukene zepulasitiki.
