Njengoba abantu sebengenile emphakathini wezimboni, ukukhiqizwa kwazo zonke izinhlobo zemikhiqizo kuye kwaqeda umsebenzi wezandla, ukukhiqizwa komshini okuzenzakalelayo kuye kwathandwa kuzo zonke izigaba zokuphila, futhi ukukhiqizwa kwemikhiqizo yepulasitiki kuyahluka, namuhla, imikhiqizo yepulasitiki icutshungulwa ngomshini wokubumba umjovo, njengamagobolondo ezinto ezihlukahlukene zasendlini kanye nemikhiqizo yedijithali evamile ekuphileni kwethu kwansuku zonke icutshungulwaukubumba umjovo. Ngabe umkhiqizo wepulasitiki ophelele ucutshungulwa kanjani emshinini wokubumba umjovo?
1. Ukushisa kanye ne-preplasticization
I-screw iqhutshwa uhlelo lokushayela, izinto ezivela ku-hopper ukuya phambili, zihlanganiswe, ku-cylinder ngaphandle kwe-heater, isikulufu kanye nomgqomo we-shear, ukungqubuzana ngaphansi komphumela wokuxuba, impahla kancane kancane iyancibilika, ekhanda lombhobho iqoqe inani elithile lepulasitiki elincibilikisiwe, ngaphansi kwengcindezi yokuncibilika, isikulufu sibuyele kancane kancane. Ibanga lokuhlehla lincike enanini elidingekayo ukuze umjovo owodwa wedivayisi yokulinganisa ulungiswe, lapho umthamo womjovo onqunywe kusengaphambili ufinyelelwa, isikulufu siyayeka ukuzungezisa futhi sihlehla.
2. Ukubamba nokukhiya
I-clamping mechanism iphusha i-mold plate kanye nengxenye enyakazayo yesikhunta efakwe ku-mold plate ephathekayo ukuze ivale futhi ikhiye isikhunta ngengxenye enyakazayo yesikhunta ku-mold plate ephathekayo ukuze kuqinisekiswe ukuthi kunganikezwa amandla anele okubamba ukuze kukhiywe isikhunta ngesikhathi sokubunjwa.
3. Ukuhambisa phambili kweyunithi yomjovo
Lapho ukuvala isikhunta sekuqediwe, sonke isihlalo somjovo siyaphushwa futhi siyiswe phambili ukuze umlomo womjovo uvumelane ngokuphelele nokuvuleka kwe-sprue okuyinhloko kwesikhunta.
4.Umjovo nokubamba ingcindezi
Ngemuva kokuthi isikhunta sigoqe kanye nombhobho kungene ngokuphelele isikhunta, isilinda somjovo we-hydraulic singena kuwoyela wengcindezi ephezulu bese siphusha isikulufu siye phambili esihlobene nomgqomo ukuze sijove incibiliko enqwabelene ekhanda lombhobho emgodini wesikhunta ngokucindezela okwanele, okubangela ukuthi ivolumu yepulasitiki inciphe ngenxa yokuncipha kwezinga lokushisa. Ukuqinisekisa ukuminyana, ukunemba kwe-dimensional kanye nezakhiwo zemishini yezingxenye zepulasitiki, kuyadingeka ukugcina ingcindezi ethile ekuncibilikeni emgodini wesikhunta ukuze ugcwalise impahla.
5. Ukucindezela kokulayisha
Lapho ukuncibilika kwesango lesikhunta kufriziwe, ingcindezi ingathululwa.
6. Idivayisi yomjovo yenza ikhophi yasenqolobaneni
Ngokuvamile, ngemva kokuqedwa kokulayishwa, isikulufu singajikeleza futhi sihlehle ukuze siqedele ukugcwalisa okulandelayo kanye nenqubo yokufaka iplasticization.
7. Vula isikhunta bese ukhipha izingxenye zepulasitiki
Ngemva kokuba izingxenye zepulasitiki ezingaphakathi kwesikhunta sezipholile futhi zisethwe, indlela yokubopha ivula isikhunta bese iphusha izingxenye zepulasitiki ezikusikhumbeni.
Kusukela ngaleso sikhathi, umkhiqizo ophelele wepulasitiki ubhekwa njengophelele, yiqiniso, izingxenye eziningi zepulasitiki zizodinga ukulandelwa ukufuthwa kwamafutha, ukuhlunga usilika, ukugxilisa isitembu esishisayo, ukuqoshwa kwe-laser nezinye izinqubo ezisizayo, bese kuhlanganiswe neminye imikhiqizo, futhi ekugcineni kwakha umkhiqizo ophelele ngaphambi kokugcina ezandleni zabathengi.
