chidziwitso chothamanga chotentha mu makina opangira jekeseni

Kugawana chidziwitso chaukadaulo wa jakisoni mold hot runner mu makina jekeseni akamaumba

Hot Runner gating system zitha kumveka ngati chowonjezera cha makina opangira jekeseni. Ntchito ya hot runner system ndikupereka kusungunuka kwa thermoplastic pafupi ndi kufa kowumbidwa kapena mwachindunji kufa adiabatically..

Wothamanga wotentha akhoza kutenthedwa pawokha, koma thermally insulated mu jekeseni nkhungu, kotero kuti akhoza kubweza payekha kutayika kwa kutentha komwe kumachitika chifukwa chokhudzana ndi “ozizira” nkhungu.

Zoumba zothamanga zotentha zagwiritsidwa ntchito bwino pokonza zida zosiyanasiyana zapulasitiki, ndipo pafupifupi zida zonse zapulasitiki zomwe zimatha kukonzedwa ndi nkhungu zozizira zimatha kukonzedwa ndi nkhungu zothamanga zotentha..

Gawo laling'ono kwambiri ndi locheperapo 0.1 magalamu, ndipo gawo lalikulu kwambiri ndi loposa 30 kilogalamu. Zoumba zothamanga zotentha zimagwiritsidwa ntchito kwambiri pazinthu zamagetsi, magalimoto, chithandizo chamankhwala, zofunika tsiku ndi tsiku, zidole, kuyika, kumanga, ndi zipangizo zamaofesi.

A wopambana otentha wothamanga nkhungu pulojekiti yofunsira imafuna maulalo angapo kuti atsimikizidwe.

Zina mwazofunikira kwambiri ndi ziwiri zaukadaulo: imodzi ndiyo kulamulira kutentha kwa pulasitiki;
Chachiwiri ndikuwongolera kayendedwe ka pulasitiki.

Makina othamanga omwe amawotcha amakhala ndi magawo otsatirawa: 1) Hot Runner mbale (ZOCHITIKA); 2) Nozzle (NOZZLE); 3) Wowongolera kutentha; 4) Mbali zothandizira.

Ubwino wa otentha othamanga amaumba:
1) Kufupikitsa akamaumba mkombero wa mbali;
2) Sungani zipangizo zapulasitiki;
3) Chepetsani zinyalala ndikuwongolera zinthu zabwino;
4) Chotsani njira zotsatila, zomwe zimathandizira kupanga automation;
5) Wonjezerani kugwiritsa ntchito ukadaulo woumba jekeseni.

Nthawi yomweyo, palinso zoperewera monga kukwera mtengo kwa nkhungu, mkulu kupanga ndondomeko zipangizo zofunika, ndi ntchito zovuta ndi kukonza.

Mitundu ndi ntchito zamakina othamanga otentha

Mukamagwiritsa ntchito ukadaulo wothamanga wotentha, kusankha kolondola kwa mtundu wa chipata ndikofunikira kwambiri. Mtundu wa chipata umatsimikizira mwachindunji kusankhidwa kwa zigawo za dongosolo la othamanga otentha ndi kupanga ndi kugwiritsa ntchito nkhungu.

Chifukwa chake, malinga ndi mitundu yosiyanasiyana ya zipata, dongosolo lothamanga lotentha likhoza kugawidwa mu mitundu itatu: otentha nsonga otentha wothamanga dongosolo, sprue hot runner system, ndi valve hot runner system. Mtundu uliwonse wa othamanga othamanga ali ndi ntchito yake yofunika. Features ndi kuchuluka kwa ntchito.

Zinthu zambiri ziyenera kuganiziridwa posankha mitundu ya zipata ndi machitidwe othamanga otentha, zofunika kwambiri zomwe ndi mtundu wa matrix apulasitiki ndi zowonjezera, kulemera ndi kukula kwa ziwalozo, zofunika za khalidwe la zigawo, moyo wa zida ndi zofunika kupanga zigawo.

1 Hot nsonga otentha wothamanga dongosolo (MFUNDO YOTHANDIZA)
Mfundo yake yogwirira ntchito ndikuphatikiza HOT TIP kumapeto kwa nozzle ndi makina oziziritsa kuti azitha kusintha bwino ndikuwongolera kutentha kwa kutentha kwa pulasitiki pachipata.. Chifukwa chake, kupanga zinthu ndi mawonekedwe a mawonekedwe a nozzle Ikani HOT TIP ndizofunikira kwambiri.HOT TIP hot Runner system ingagwiritsidwe ntchito pokonza mapulasitiki ambiri a crystalline ndi amorphous monga PP., Pofuna kupewa kuipitsidwa kwa zopangira ndi kukhalapo kwa zinthu zakale kapena zonyansa m'mphepete mwa screw ndi zowonjezera., PS, Zithunzi za LCP, Pa, PET, Mtengo PBT, PEEK, Choph, PEI, PMMA, Zithunzi za ABSPVC, PC , PSU, TPU, etc.. Nthawi zambiri, otentha nsonga zipata makamaka ntchito pokonza magawo ang'onoang'ono ndi sing'anga-kakulidwe, makamaka pokonza magawo ang'onoang'ono.

Kutalika kwa gawo lachipata nthawi zambiri kumakhala pakati pa 0.5mm-2.0mm. The kutsimikiza mtima wa m'mimba mwake wa gawo la chipata makamaka amatsimikiziridwa ndi kulemera ndi khoma makulidwe a gawolo, ndipo ndithudi zofunika zakuthupi ndi mbali zina ziyenera kuganiziridwa.

Ngati chipata chokhala ndi mainchesi ang'onoang'ono chimagwiritsidwa ntchito, chipata chidzatsekedwa mwamsanga pambuyo pa siteji yodzaza jekeseni, zizindikiro za pachipata pa gawolo zidzakhala zazing'ono, ndipo pamwamba pa gawolo padzakhala maonekedwe abwino ndi abwino.

Ngati mainchesi a chipatacho ndi ochepa kwambiri, kumeta ubweya kudzakhala kwakukulu kwambiri pamene pulasitiki ikuyenda pachipata, zomwe zingawononge kwambiri mawonekedwe a mamolekyu a pulasitiki osungunuka kapena zowonjezera mu pulasitiki, zomwe zimapangitsa kuti pakhale mankhwala osayenerera omwe sangathe kukwaniritsa zofunikira zogwiritsira ntchito.

Posankha kukula kwa chipata, mchitidwe wanthawi zonse ndikuzindikira kukula kwa chipata molingana ndi makulidwe a khoma pachipata cha gawo: gate diameter = (0.75-1.0) makulidwe a khoma pa chipata cha mbali. Mtengo wocheperako umagwiritsidwa ntchito pokonza mapulasitiki osavuta kuyenda, ndipo mtengo wokulirapo umagwiritsidwa ntchito pokonza mapulasitiki othamanga kwambiri kapena mapulasitiki omwe amamva kumeta ubweya.
Kawirikawiri chipata chowotcha chimatsegulidwa mwachindunji pa gawolo, koma imathanso kutsegulidwa pa wothamanga wozizira ndiyeno chipata chozizira chimatsegulidwa pagawo. Iyi ndi ndondomeko ya nkhungu yomwe imaphatikizapo wothamanga wotentha ndi wothamanga wozizira. Mukamagwiritsa ntchito zipata zotentha zopangira zida zapulasitiki, padzakhala nthawi zonse zipata zochulukirapo kapena zochepa pazigawozo.

Nthawi zambiri zizindikiro za zipata zimakhala zapamwamba kuposa pamwamba pa gawolo, kukhudza kukongola kwa gawo kapena kukhudza msonkhano ndi mbali zina. Chifukwa chake, posankha malo a chipata, yesetsani kuyika chipata mu gawo lobisika la gawolo.

2SPRUE GATING system (KUGWIRITSA NTCHITO SPRUE)
Mu sprue otentha wothamanga dongosolo, pulasitiki imalowa mu nkhungu kudzera mwa wothamanga wotseguka (TSEGULANI PIPE). Kutaya kwamphamvu kwa pulasitiki pachipata ndi kochepa. Dongosolo la sprue hot runner ndiloyenera kuumba jekeseni wa zigawo zapakati ndi kulemera kwake.

Ubwino wogwiritsa ntchito sprue hot runner system ndikuti pulasitiki imatsika pang'ono kukameta ubweya ikamadutsa pachipata ndikudzaza nkhungu., kupsyinjika kotsalira pambuyo popangidwa ndi gawo laling'ono, mlingo wa deformation ndi wochepa, ndipo mphamvu yamakina ya gawolo ndi yabwino. Poyerekeza ndi zipata otentha nsonga, zipata za sprue ndi zazikulu kukula kwake, kotero zizindikiro za zipata zingakhalenso zazikulu.

Chifukwa chake, m'mikhalidwe yabwino, nkhungu ndi zofunika okhwima kwa aesthetics pachipata nthawi zambiri ntchito pulasitiki jekeseni akamaumba; ndi zigawo zamkati zomwe sizifuna kukongola kwakukulu kwa chipata zimatha kupangidwa ndi sprue-type hot runner system..

Anthu nthawi zambiri amagwiritsa ntchito sprue sprue kuphatikiza ndi wothamanga ozizira, ndiye, mphuno ya sprue imagwiritsidwa ntchito ngati wothamanga wamkulu, ndipo sprue sprue imatsegulidwa pa wothamanga ozizira. Mu ntchito iyi, chipata cha sprue chikhoza kutsegulidwa mokulirapo kuti athandizire kuyenda kwa pulasitiki, chifukwa palibe amene amasamala za kukula kwa zizindikiro za pachipata pa wothamanga ozizira.

Zofanana ndi kugwiritsa ntchito kachitidwe ka hot-tip hot runner, kuwongolera kutentha kwa pulasitiki ndi kutentha kwa nkhungu pachipata ndikofunikira kwambiri. Dongosolo lozizira lapadera liyenera kukhazikitsidwa kuzungulira chipata. Chifukwa kukula kwa chipata cha sprue ndi chachikulu, ngati kutentha pachipata sikukuyendetsedwa bwino, ndizotheka kuti chipata sichingathe kusindikiza pulasitiki yomwe ikuyenda pambuyo potsegula nkhungu.

Kuyika kwa nozzle kwa sprue hot runner system kumakhalanso ndi makulidwe osiyanasiyana ndi mawonekedwe ndi kusintha mu zipangizo zopangira, zomwe ziyenera kuganiziridwa pamodzi ndi mtundu wa pulasitiki wokonzedwa (monga crystalline pulasitiki kapena pulasitiki amorphous) ndi kuzizira kwa chipata.

Ngati muli ndi mafunso pa jekeseni akamaumba ,plz khalani omasuka kufunsa Gulu la FLYSE,tidzakupatsani utumiki wabwino kwambiri!
