Njengoba abantu sebengenile emphakathini wezimboni, ukukhiqizwa kwazo zonke izinhlobo zemikhiqizo kususe umsebenzi wezandla, ukukhiqizwa komshini okuzenzakalelayo kuye kwathandwa kuzo zonke izigaba zokuphila, futhi ukukhiqizwa kwemikhiqizo yepulasitiki akusafani, namuhla, imikhiqizo yepulasitiki ithandwa kakhulu. ecutshungulwa ngomshini wokubumba umjovo, njengamagobolondo ezinto zikagesi ezihlukahlukene zasendlini kanye nemikhiqizo yedijithali evamile ekuphileni kwethu kwansuku zonke acutshungulwaukubumba 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, kusilinda ngaphandle kwe-heater, isikulufu kanye nomgqomo we-shear, ukungqubuzana ngaphansi komphumela wokuxuba, impahla iyancibilika kancane kancane, ekhanda le-shear. umgqomo uqongelele inani elithile lepulasitiki elincibilikisiwe, ngaphansi kwengcindezi yokuncibilika, isikulufu sibuyela emuva 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 enyakazayo ukuze ivale futhi ikhiye isikhunta ngengxenye enyakazayo yesikhunta ku-mold plate 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 ocindezelayo futhi siphushela isikulufu phambili esihlobene nomgqomo ukuze sijove incibiliko enqwabelene ekhanda lombhobho emgodini wesikhunta ngengcindezi eyanele, okwenza umthamo wepulasitiki unciphe 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 wepulasitiki ophelele ubhekwa njengophelele, yiqiniso, izingxenye eziningi zepulasitiki zizodinga ukulandelwa ukufafaza uwoyela, ukuhlolwa kwesilika, ukugxiviza okushisayo, ukuqoshwa kwe-laser nezinye izinqubo ezisizayo, bese zihlanganiswa neminye imikhiqizo, futhi. ekugcineni yakha umkhiqizo ophelele ngaphambi kokugcina ezandleni zabathengi.
Isikhathi sokuthumela: Sep-14-2022
