Ukubumba i-Pulp, njengommeli odumileyo wokupakisha oluhlaza, uthandwa ngabanini beempawu. Kwinkqubo yokuvelisa iimveliso ezibunjiweyo ze-pulp, i-mold, njengenxalenye ephambili, ineemfuno eziphezulu zobuchwepheshe zophuhliso kunye noyilo, utyalo-mali oluphezulu, umjikelo omde kunye nomngcipheko omkhulu. Ke, ngawaphi amanqaku aphambili kunye nezilumkiso kuyilo lwezibungu zeplastiki zephepha? Apha ngezantsi, siza kwabelana ngamava kuyilo lokupakisha lwesakhiwo ukuze ufunde kwaye uphonononge uyilo lokubumba i-pulp.
01Ukwenza uMngundo
Isakhiwo siquka i-convex mold, i-concave mold, i-mesh mold, isihlalo sokubumba, i-mold back cavity, kunye negumbi lomoya. I-mesh mold ngumzimba ophambili wokungunda. Njengoko i-mesh mold ilukwe kwintsimbi okanye iingcingo zeplastiki ezinobubanzi be-0.15-0.25mm, ayinakho ukuzimela ngokuzimeleyo kwaye kufuneka ifakwe kumphezulu wokubumba ukuze isebenze.
Umqolo ongemva wokungunda ngumgodi owenziwe ngobungqimba obuthile kunye nokumila okudityaniswa ngokupheleleyo nomphezulu wokusebenza wokungunda, ngokunxulumene nesihlalo sokungunda. I-convex kunye ne-concave molds liqokobhe elinodonga oluthile oluthile. Indawo yokusebenza yesikhunta ixhunywe kwisigxina sangasemva ngemigodi emincinci esasazwa ngokufanayo.
I-mold ifakwe kwi-template yomshini wokubumba ngokusebenzisa isihlalo sokubumba, kwaye igumbi lomoya lifakwe kwelinye icala le template. Igumbi lomoya liqhagamshelwe kumqolo ongasemva, kwaye kukho neziteshi ezimbini zomoya ocinezelekileyo kunye ne-vacuum kuyo.
02Ukubumba ukungunda
I-mold mold yi-mold engena ngokuthe ngqo kwiphepha elimanzi elingenanto emva kokwenza kwaye linemisebenzi yokufudumeza, ukuxinzelela, kunye nokuphelelwa ngamanzi emzimbeni. Iimveliso ezenziwe ngobumba bokubumba zinendawo egudileyo, imilinganiselo echanekileyo, ukuqina, kunye nokuqina okulungileyo. Itafile elahlayo yenziwa kusetyenziswa le mold. Kwipakethe yemizi-mveliso, ezinye ezincinci, ezichanekileyo, kunye nezixa ezikhulu zezinto ezincinci zipakishwe umaleko kumgangatho, kunye neemveliso zokupakisha ezisetyenziselwa ukubeka phakathi kwendawo nganye. Ukuba iimveliso ezibunjiweyo ze-pulp zisetyenzisiwe, kufuneka zenziwe kusetyenziswa ukubumba.
Nangona kunjalo, uninzi lweemveliso zokupakishwa kwamashishini zisebenza kwicala elinye kwaye azifuni ukusetwa kobushushu. Zingomiswa ngokuthe ngqo. Ubume bobunjwa bokubumba bubandakanya i-convex mold, i-concave mold, i-mesh mold, kunye nento yokufudumala. I-convex okanye i-concave mold ene-mesh mold ine-drainage kunye nemingxuma yokukhupha. Ngethuba lokusebenza, iphepha elimanzi elingenanto liqala ligxininiswe ngaphakathi kwi-mold yokubumba, kwaye i-20% yamanzi igxininiswe kwaye ikhutshwe. Ngeli xesha, umxholo wamanzi wephepha elimanzi elingenanto liyi-50-55%, ebangela ukuba amanzi asele emva kokuba iphepha elimanzi elingenanto lifudunyezwe ngaphakathi kwi-mold ukuba libe ngumphunga kwaye likhutshwe. Iphepha elimanzi elingenanto liyacofwa, lomiswe, kwaye libunjwe ukwenza imveliso.
I-mesh mold kwi-mold mold ingabangela iimpawu ze-mesh kumphezulu wemveliso, kwaye i-mesh mold inokonakalisa ngokukhawuleza ngexesha lokukhupha rhoqo. Ukusombulula le ngxaki, umyili wokungunda wenze i-mesh yokungunda yasimahla, eyenziwa kusetyenziswa ubhedu olusekelwe kwi-spherical powder metallurgy. Kwiminyaka emibini edlulileyo, emva kokuphuculwa kwezakhiwo ezininzi kunye nokukhethwa kobungakanani obufanelekileyo be-powder particle, ubomi be-mesh free shape mold eveliswayo ngamaxesha angama-10 e-mesh mold, kunye nokunciphisa iindleko ze-50%. Iimveliso zephepha eziveliswayo zinokuchaneka okuphezulu kunye nemigangatho egudileyo yangaphakathi nangaphandle.
03I-Hot Pressing Mold
Emva kokumisa, iphepha elimanzi elingenanto lingena kwi-deformation. Xa ezinye iindawo zenza utshintsho olunzima okanye zifuna ukuchaneka okuphezulu kwinkangeleko yemveliso, imveliso ingena kwinkqubo yokubumba, kwaye i-mold esetyenzisiweyo ibizwa ngokuba yi-shaping mold. Olu bumba lufuna izinto zokufudumeza, kodwa lunokwenziwa ngaphandle kwe-mesh mold. Iimveliso ezifuna ukubunjwa kufuneka zigcine ubumanzi obuyi 25-30% ngexesha lokumisa ukuze kube lula ukumila.
Kwimveliso yokuvelisa, kunzima ukulawula umthamo wamanzi, okwenza kube nzima kwimveliso ukuhlangabezana neemfuno zomgangatho. Umvelisi wenze i-spray shape mold, kwaye imingxuma yokutshiza yenziwa kwi-mold ehambelana neendawo ezifuna ukubunjwa. Xa usebenza, iimveliso zifakwa kwi-mold yokubumba emva kokuba zomiswe kakuhle. Ngelo xesha, umngxuma wokutshiza kwi-mold isetyenziselwa ukutshiza okutshisa ngokucinezela iimveliso. Olu ngundo lufana noko nentsimbi yokutshiza kwishishini lempahla.
04Ukuhanjiswa kweMold
I-mold yokudlulisa i-workstation yokugqibela yenkqubo yonke, kwaye umsebenzi wayo oyintloko kukudlulisa ngokukhuselekileyo umkhiqizo kwi-mold encedisayo edibeneyo ukuya kwi-tray yokufumana. Kumngundo wodluliselo, uyilo lwayo lolwakhiwo kufuneka lube lula kangangoko, lube nemingxunya yokufunxa elungelelaniswe ngokulinganayo ukuqinisekisa ukuba imveliso ingabhengeza ngokutyibilikayo kumphezulu wokungunda.
05Ukucheba Mold
Ukuze wenze iimveliso ezibunjiweyo zephepha zicoceke kwaye zihle, iimveliso ezibunjiweyo zephepha ezineemfuno zembonakalo ephezulu zixhotyiswe ngeenkqubo zokusika edge. Umngundo wokufa usetyenziselwa ukucheba imiphetho erhabaxa yeemveliso ezibunjiweyo zephepha, ezaziwa ngokuba ngumngundo wokusika.
