Weld mitsetse ndiyo yakajairika pakati pehurema hwakawanda hwejekiseni kuumbwa zvigadzirwa.Kunze kwezvikamu zvishoma zvakaumbwa majekiseni ane maumbirwo akareruka ejometri, mitsetse yeweld inoitika pazvikamu zvakawanda zvakaumbwa jekiseni (kazhinji muchimiro chemutsara kana V-shaped groove), kunyanya kune zvihombe uye zvakaoma zvigadzirwa zvinoda kushandiswa kweakawanda gedhi molds. uye kuisa.
Weld line haingokanganisa kutaridzika kwemhando yezvikamu zvepurasitiki, asiwo inokanganisa michina yezvikamu zvepurasitiki, senge simba rekuita, kusimba kwesimba, kureba panguva yekuzorora, nezvimwewo. Mukuwedzera, weld line inewo kukanganisa kwakakomba kugadzirwa kwechigadzirwa uye hupenyu hwezvikamu zvepurasitiki.Nokudaro, inofanira kudziviswa kana kuvandudzwa zvakanyanya sezvinobvira.
Zvinonyanya kukonzera weld line ndezvi: kana purasitiki yakanyungudutswa inosangana nekuisa, gomba, nzvimbo ine discontinuous flow rate kana nzvimbo ine yakakanganiswa kuzadza zvinhu kuyerera mu mold cavity, akawanda melts converge;Kana jekiseni rekuzadza gedhi rikaitika, zvinhu zvacho hazvigone kusanganiswa zvizere.
(1) Tembiricha yakaderera
Iyo shunting uye inotenderedza zvimiro zveyakadzika tembiricha yakanyungudutswa zvinhu hazvina kunaka, uye weld mitsetse iri nyore kugadzira.Kana mukati uye kunze kwekunze kwezvikamu zvepurasitiki zvine welding mitsetse yakanaka panzvimbo imwe chete, zvinowanzoitika nekuda kwekushata kwakashata kunokonzerwa nekuderera kwezvinhu tembiricha.Panyaya iyi, tembiricha yebhari uye nozzle inogona kukwidziridzwa zvakakodzera kana kutenderera kwejekiseni kunogona kuwedzerwa kuwedzera tembiricha yezvinhu.Panguva imwecheteyo, huwandu hwemvura inotonhorera inopfuura nemuforoma inofanira kudzorwa, uye tembiricha yekuumba inofanira kuwedzerwa zvakakodzera.
(2)Moldkuremara
Iyo magadzirirwo maparamendi e mold gating system ane simba guru pakusanganiswa kweiyo flux, nekuti iyo isina kunaka fusion inonyanya kukonzerwa neshunt uye confluence yekuyerera.Naizvozvo, mhando yegedhi ine zvishoma diversion ichagamuchirwa zvakanyanya sezvinobvira uye nzvimbo yegedhi ichave yakasarudzwa zvine musoro kudzivirira kusawirirana kwekuzadza mwero uye kukanganisa kwekuzadza kuyerera kwezvinhu.Kana zvichibvira, gedhi rimwe chete rinofanira kusarudzwa, nokuti gedhi iri hariburitse nzizi dzakawanda dzekuyerera kwezvinhu, uye zvinhu zvakanyungudutswa hazvizoshanduki kubva kumativi maviri, saka zviri nyore kudzivisa mitsetse ye weld.
(3) Mold yakashata inopera
Kana mutsara wekusanganiswa wechinhu chakanyunguduka uchipindirana nemutsara wekuvhara mold kana caulking, mhepo inofambiswa nehova dzakawanda dzezvinhu mugomba remukati inogona kuburitswa kubva mugomba rekuvhara mold kana caulking;Nekudaro, kana iyo welding mutsara isingaenderane neiyo mold yekuvhara mutsara kana caulking, uye gomba remhepo harina kuiswa zvakanaka, mhepo yakasara mugomba rekuumbwa inofambiswa neinoyerera zvinhu haigone kuburitswa.Iyo bubble inomanikidzwa pasi pekumanikidzwa kwakanyanya, uye vhoriyamu inodzikira zvishoma nezvishoma, uye pakupedzisira yakatsikirirwa kuita imwe pfungwa.Nekuti simba remamorekuru remweya wakadzvanyirirwa rinoshandurwa kuita simba rekupisa pasi pekumanikidzwa kukuru, tembiricha iri panzvimbo yekuunganidza zvinhu zvakanyungudutswa inokwira.Kana tembiricha yaro yaenzana kana kuti yakakwira zvishoma pane tembiricha yekuparara kweiyo mbishi, maYellow dots anozoonekwa parikunyungudika.Kana tembiricha yakakwira zvakanyanya kudarika tembiricha yekuora yemidziyo, madota matema anozoonekwa parikunyungudika.
(4) Kushandiswa kusina kunaka kwemumiririri wekusunungura
Yakawandisa yekuburitsa mumiririri kana isiriyo mhando inokonzeresa weld mitsetse pamusoro pezvikamu zvepurasitiki.Mukuumba jekiseni, shoma shoma yekuburitsa mumiririri inowanzoiswa zvakaenzana chete kune zvikamu zvisiri nyore kugadzira, senge tambo.Muchidimbu, huwandu hwekusunungura mumiriri hunofanira kuderedzwa zvakanyanya sezvinobvira.
