Ukufakelwa kombhobho wokubumba i-injection kaninzi idibana nento yokuba i-mold ayikwazi ukuzaliswa kwinkqubo yokucubungula. Xa umatshini wokubumba inaliti yaqala ukusebenza, ngenxa yokuba ubushushu bokubumba buphantsi kakhulu, ilahleko yobushushu yezinto ezinyibilikisiweyo zePVC yayinkulu, eyayithande ukuqiniswa kwangaphambili, kwaye ukuxhathisa komgodi wokungunda kwakunkulu, kwaye izinto azikwazi. gcwalisa umngxuma. Le nto iqhelekile kwaye yeyexeshana. Iza kunyamalala ngokuzenzekelayo emva kwesitofu esiqhubekayo sokubumba kwedijithali. Ukuba isikhunta asikwazi ukuzaliswa ngalo lonke ixesha, qwalasela le miqathango ilandelayo kwaye wenze uhlengahlengiso olufanelekileyo:

Iibhabhu kumbhobho

Amaqamza obushushu aveliswa ngenxa yobushushu obuphezulu bobushushu. Ubushushu benkqubo ephezulu kakhulu buya kubangela amaqamza kwizinto eziguquguqukayo kwimathiriyeli ekrwada, kwaye ziya kubola ngokuyinxenye.I-PVCIsixhobo sokuvelisa amaqamza, awaziwa ngokuba ngamaqamza ashushu. Lungisa ngokufanelekileyo isantya sokutofa

Isantya sokutofa sikhawuleza kakhulu. Ngenxa yokuba inkqubo yokubumba yeI-PVC-UIimveliso ezibunjiweyo zesitofu kufuneka zamkele isantya esisezantsi sokutofa kunye noxinzelelo oluphezulu lwesitofu. Isantya sokutofa singalungiswa ngokufanelekileyo.

Ukuba isango lincinci kakhulu okanye icandelo lomjelo wokuhamba lincinci kakhulu, ukuchasana kokuhamba kwezinto kukhulu kakhulu. Isango kunye necandelo lembaleki linokwandiswa ukunciphisa ukuxhatshazwa kwe-melt flow.

Isiqulatho sokufuma okanye ezinye izinto eziguquguqukayo kwimathiriyeli ekrwada ziphezulu kakhulu okanye izinto ezingasetyenziswanga zigcinwe ixesha elide, kwaye ukufuma okusemoyeni kuyafunxwa. Lawula ngokungqongqo umxholo wezinto eziguquguqukayo kwizinto eziluhlaza xa kuthengwa izinto eziluhlaza, kunye nezixhobo ezincedisayo akufanele zigcinwe ixesha elide ngexesha okanye imimandla enomswakama ophezulu emoyeni.

Iglosi yemveliso engalunganga

Iglosi yomphezulu yeemveliso ezibunjiweyo zenaliti yePVC inxulumene ubukhulu becala nolwelo lwemathiriyeli yePVC. Ngoko ke, ukuphuculwa kwe-fluidity yezinto ngumlinganiselo obalulekileyo wokuphucula iimveliso. Ngenxa yokuba ubushushu bezinto ezinyibilikisiweyo ziphantsi kwaye umbane wezinto eziphathekayo uhlwempuzekile, ubushushu bokufudumala bezinto eziphathekayo bunokwandiswa ngokufanelekileyo, ngakumbi ukushisa kwi-nozzle.

Ifomula ayinangqiqo, ukwenzela ukuba iplastiki yezinto eziphathekayo ingekho okanye i-filler ininzi kakhulu, ifomyula kufuneka ihlengahlengiswe, kwaye umgangatho weplastiki kunye ne-fluidity yezinto kufuneka uphuculwe ngokudityaniswa okufanelekileyo kwezinto zokusebenza, kunye isixa sokugcwaliswa kufuneka silawulwe.

Ukupholisa komngundo okungonelanga, phucula isiphumo sokupholisa ngundo. Ukuba ubungakanani besango buncinci kakhulu okanye i-runner cross-section incinci kakhulu, ukuchasana kukhulu kakhulu. Unokwandisa i-cross-section yembaleki ngokufanelekileyo, ukwandisa isango, kunye nokunciphisa ukuxhathisa.

Isiqulatho sokufuma okanye ezinye izinto eziguquguqukayo kwimathiriyeli ekrwada ziphezulu kakhulu. Izinto eziluhlaza zingomiswa ngokupheleleyo, okanye ukufuma okanye ukuguquguquka kunokususwa ngezinto eziphathekayo. Ukuba i-exhaust ihlwempuzekile, i-groove yokukhupha ingadibaniswa okanye indawo yesango ingatshintshwa.

Kukho imigca ye weld ecacileyo

Ubushushu bezinto ezincibilikisiweyo ziphantsi, kwaye ukushisa kombhobho kunokunyuswa ngokufanelekileyo, ngokukodwa ukushisa kwe-nozzle kufuneka kunyuswe. Ukuba uxinzelelo lwenaliti okanye isantya sokutofa sisezantsi, uxinzelelo lwenaliti okanye isantya sokutofa sinokunyuswa ngokufanelekileyo.

Ukuba iqondo lobushushu lokungunda liphantsi, iqondo lobushushu lokungunda linganyuswa ngokufanelekileyo. Ukuba isango lincinci kakhulu okanye icandelo lomnqamlezo lomgijimi lincinci kakhulu, unokwandisa umgijimi okanye ukwandise isango ngokufanelekileyo.

Ukukhupha umngundo ombi, phucula ukusebenza kokungunda, yongeza i-grooves yokukhupha. Umthamo we-slug ebandayo kakuhle uncinci kakhulu, ngoko ke umthamo we-slug ebandayo unokunyuswa ngokufanelekileyo.

Isixa se-lubricant kunye ne-stabilizer kwifomula ininzi kakhulu, kwaye isixa sabo sinokulungiswa. Ukuseta kwecavity akunangqiqo kwaye uyilo lwayo lunokulungiswa.

Iimpawu ezinzulu zokutshona

Uxinzelelo lwenaliti ye-Gaoan lusezantsi, ngoko ke uxinzelelo lwenaliti lunokwenyuka ngokufanelekileyo. Uxinzelelo olumiselweyo lokubamba ixesha alanelanga, unokwandisa ixesha lokubamba uxinzelelo ngokufanelekileyo.

Ixesha lokupholisa elimiselweyo alanelanga, unokwandisa ixesha lokupholisa ngokufanelekileyo. Ukuba isixa sesol asanelanga, nyusa isixa sesol ngokufanelekileyo.

Ukuthuthwa kwamanzi kwi-mold ayilingani, kwaye isiphaluka sokupholisa sinokuhlengahlengiswa ukwenza zonke iindawo zokubumba zipholile ngokulinganayo. Ubungakanani besakhiwo se-mold gating system incinci kakhulu, kwaye isango linokwandiswa okanye i-main, isebe, kunye ne-runner i-cross-sectional dimensions inokwandiswa.

Kunzima ukuyilungisa

Ubunzima bokubunjwa bubangelwa yi-mold kunye nenkqubo engafanelekanga, kodwa kwiimeko ezininzi kubangelwa yindlela engafanelekanga yokubunjwa kwe-mold. Kukho umatshini we-hook wezinto ezibonakalayo kwindlela yokudiliza, enoxanduva lokuhuka izinto ezibandayo kwindawo ephambili, imbaleki kunye nesango: indlela yokukhupha isebenzisa intonga yokukhupha okanye ipleyiti ephezulu ukukhupha imveliso kwisibuko esishukumayo. Ukuba i-angle ye-demolding ayanelanga, ukudiliza kuya kuba nzima. Kufuneka kubekho uxinzelelo olwaneleyo lwe-pneumatic ngexesha lokukhutshwa kwe-pneumatic kunye ne-demolding. , Ngaphandle koko kuya kubakho ubunzima ekubumbeni. Ukongeza, isixhobo sokutsala esingundoqo somphezulu wokwahlula, isixhobo sokutsala umsonto wentambo, njl.njl zonke ziyinxalenye ebalulekileyo kwisakhiwo sokubunjwa, kunye noyilo olungafanelekanga luya kubangela ubunzima bokubunjwa. Ngoko ke, kuyilo lokubumba, indlela yokudiliza ikwayinxalenye ekufuneka iqwalaselwe. Ngokolawulo lwenkqubo, ubushushu obuphezulu kakhulu, ukutya okuninzi kakhulu, uxinzelelo lwenaliti ephezulu kakhulu, kunye nexesha elide lokupholisa liza kubangela ubunzima bokudiliza.

Isishwankathelo, iingxaki ezahlukeneyo zomgangatho ziya kwenzeka kulungiso lweI-PVC-UIimveliso ezibunjiweyo zesitofu, kodwa izizathu zezi ngxaki zikwizixhobo, imixokelelwane, iifomyula kunye neenkqubo. Ngethuba nje kukho izixhobo ezipheleleyo kunye nokubumba, iifomyula ezifanelekileyo kunye neenkqubo, iingxaki zinokuphetshwa. Kodwa kwimveliso yangempela, ezi ngxaki zihlala zivela, okanye zivela ngaphandle kokwazi izizathu kunye nezisombululo, kuxhomekeke ekuqokeleleni amava. Amava okusebenza atyebileyo yenye yeemeko zokuqinisekisa imveliso egqibeleleyo.
