Ukubumba i-pulp, njengommeli odumileyo wokupakisha oluhlaza, kuyathandwa ngabanini bophawu. Kwinkqubo yokuvelisa iimveliso ezibunjiweyo ze-pulp, ukubumba, njengenxalenye ebalulekileyo, kuneemfuno zobugcisa eziphezulu zophuhliso kunye noyilo, utyalo-mali oluphezulu, umjikelo omde, kunye nomngcipheko ophezulu. Ngoko ke, zeziphi iingongoma eziphambili kunye namanyathelo okhuseleko kuyilo lwee-mold zeplastiki zephepha? Ngezantsi, siza kwabelana ngamava athile kuyilo lwesakhiwo sokupakisha ukuze ufunde kwaye uphonononge uyilo lwe-mold lwe-pulp molding.
01Ukwakha Umngundo
Isakhiwo siqulathe isikhunta esijijekileyo, isikhunta esijijekileyo, isikhunta esineemesh, isihlalo sesikhunta, umngxuma ongasemva wesikhunta, kunye negumbi lomoya. Isikhunta esineemesh sisixhobo esiphambili sesikhunta. Njengoko isikhunta esineemesh silukiwe ngeengcingo zesinyithi okanye zeplastiki ezinobubanzi obuyi-0.15-0.25mm, asinakwenziwa ngokwaso kwaye kufuneka sinamathele kumphezulu wesikhunta ukuze sisebenze.
Umngxuma ongasemva wesikhunta ngumngxuma owenziwe bubukhulu obuthile kunye nemilo ehambelana ngokupheleleyo nomphezulu osebenzayo wesikhunta, xa kuthelekiswa nesihlalo sesikhunta. Iisikhunta ezingqukuva kunye nezingqukuva ziyigobolondo elinobukhulu obuthile bodonga. Umphezulu osebenzayo wesikhunta uqhagamshelwe kumngxuma ongasemva ngemingxuma emincinci esasazwe ngokulinganayo.
I-mold ifakwe kwi-template yomatshini wokubumba ngesihlalo se-mold, kwaye igumbi lomoya lifakwe kwelinye icala le-template. Igumbi lomoya liqhagamshelwe kumngxuma ongasemva, kwaye kukwakho nemijelo emibini yomoya ocinezelweyo kunye ne-vacuum kuyo.
02Ukubumba isikhunta
Isikhunta sokubumba sisikhunta esingena ngqo kwiphepha elimanzi elingenanto emva kokwakheka kwaye sinemisebenzi yokufudumeza, ukucinezela, kunye nokuphelelwa ngamanzi emzimbeni. Iimveliso ezenziwe ngesikhunta sokubumba zinomphezulu ogudileyo, ubukhulu obuchanekileyo, ukuqina, kunye nokuqina okuhle. Izitya zetafile ezilahlwayo zenziwa kusetyenziswa esi sikhunta. Kwiphakheji yemizi-mveliso, ezinye izinto ezincinci, ezichanekileyo, nezininzi zipakishwa umaleko ngomaleko, kunye neemveliso zokupakisha ezisetyenziselwa ukubeka phakathi komaleko ngamnye. Ukuba kusetyenziswa iimveliso ezibunjiweyo zepulp, kufuneka zenziwe kusetyenziswa izikhunta zokubumba.
Nangona kunjalo, uninzi lweemveliso zokupakisha zemizi-mveliso zisebenza kwicala elinye kwaye azifuni ubushushu. Zingomiswa ngqo. Ulwakhiwo lwesikhunta sokubumba luquka isikhunta esingqukuva, isikhunta esingqukuva, isikhunta se-mesh, kunye ne-heating element. Isikhunta esingqukuva okanye esingqukuva esinesikhunta se-mesh sinemingxuma yokukhupha amanzi kunye ne-exhaust. Ngexesha lokusebenza, ikhunta elimanzi lephepha liqala licinezelwe ngaphakathi kwisikhunta sokubumba, kwaye i-20% yamanzi iyacinezelwa kwaye ikhutshwe. Ngeli xesha, umxholo wamanzi wekhunta elimanzi lephepha yi-50-55%, nto leyo ebangela ukuba amanzi aseleyo emva kokuba ikhunta elimanzi lephepha lifudunyezwe ngaphakathi kwisikhunta atshiswe kwaye akhutshwe. Ikhunta elimanzi lephepha liyacinezelwa, lomiswe, kwaye libunjwe ukuze lenze imveliso.
I-mesh mold kwi-mold yokubumba inokubangela amabala e-mesh kumphezulu wemveliso, kwaye i-mesh mold inokonakalisa ngokukhawuleza ngexesha lokukhupha rhoqo. Ukusombulula le ngxaki, umyili we-mold uye wayila i-mold engenama-mesh, eyenziwa kusetyenziswa i-copper based spherical powder metallurgy. Kwiminyaka emibini edlulileyo, emva kokuphuculwa okuninzi kwesakhiwo kunye nokukhethwa kobukhulu obufanelekileyo be-powder particles, ixesha lokuphila kwe-mold engenama-mesh eveliswayo liphindwe kalishumi kune-mold ye-mesh, ngokunciphisa iindleko ngama-50%. Iimveliso zephepha eziveliswayo zinomgangatho ophezulu kunye nobuso obugudileyo bangaphakathi nangaphandle.
03Umngundo oshushu ocinezelayo
Emva kokomiswa, iphepha elingenanto limanzi liyatshintshatshintsha. Xa ezinye iindawo zitshintshatshintsha kakhulu okanye zifuna ukuchaneka okuphezulu kwimbonakalo yemveliso, imveliso itshintsha indlela yokubumba, kwaye isikhunta esisetyenziswayo sibizwa ngokuba yisikhunta sokubumba. Esi sikhunta sikwafuna izinto zokufudumeza, kodwa singenziwa ngaphandle kwesikhunta se-mesh. Iimveliso ezifuna ukubumba kufuneka zigcine umxholo womswakama we-25-30% ngexesha lokomiswa ukuze kube lula ukubumba.
Kwimisebenzi yokuvelisa, kunzima ukulawula umthamo wamanzi, nto leyo eyenza kube nzima ukuba imveliso ihlangabezane neemfuno zomgangatho. Umenzi uyile isikhunta sokufutha, kwaye kwenziwa imingxunya yokufutha kwisikhunta esihambelana neendawo ezifuna ukufutha. Xa zisebenza, iimveliso zifakwa kwisikhunta sokufutha emva kokuba zomile kakuhle. Kwangaxeshanye, umngxunya wokufutha kwisikhunta usetyenziselwa ukucinezela iimveliso ngobushushu besifutho. Esi sikhunta sifana kancinci nesinyithi sokufutha kwishishini lempahla.
04Ukudlulisa iMold
Isikhunta sokudlulisa sisixhobo sokugqibela somsebenzi kuyo yonke le nkqubo, kwaye umsebenzi waso ophambili kukudlulisa ngokukhuselekileyo imveliso ukusuka kwisikhunta esincedisayo esidityanisiweyo ukuya kwitreyi yokwamkela. Kwisikhunta sokudlulisa, uyilo lwaso lwesakhiwo kufuneka lube lula kangangoko, kunye nemingxunya yokufunxa ecwangciswe ngokulinganayo ukuqinisekisa ukuba imveliso inokufunxa kakuhle kumphezulu wesikhunta.
05Ukucheba Umngundo
Ukuze iimveliso ezibunjiweyo zephepha zicoceke kwaye zibe ntle, iimveliso ezibunjiweyo zephepha ezineemfuno eziphezulu zixhotyiswe ngeenkqubo zokusika imiphetho. Ii-die cutting molds zisetyenziselwa ukucheba imiphetho erhabaxa yeemveliso ezibunjiweyo zephepha, ezaziwa ngokuba zii-edge cutting molds.
