Nthawi zambiri nkhungu imakhala ndi gawo lokhalokha komanso lopanda nkhonya.Nthawi zambiri nkhungu sifunika kuumitsa.Kuwomba komwe kumayendetsedwa ndi patsekeke ndikocheperako kuposa kuumba kwa jekeseni, nthawi zambiri 0.2 ~ 1.0MPG, ndipo mtengo wake ndi wotsika.
Chojambula cha mawonekedwe a nkhungu
Zinthu za nkhungu
Nthawi zambiri, aloyi ya aluminiyamu imagwiritsidwa ntchito popanga, ndipo beryllium mkuwa kapena aloyi yamkuwa imagwiritsidwanso ntchito pazinthu zowononga mphira monga PVC ndi POM.Kwa nkhungu zomwe zimakhala ndi zofunikira pa moyo wautumiki, monga mapulasitiki opangira makina a ABS, PC, POM, PS, PMMA, etc., chitsulo chosapanga dzimbiri chimafunika kugwiritsidwa ntchito popanga nkhungu.
nkhungu
Mfundo zazikuluzikulu za mapangidwe a nkhungu
Polekanitsa pamwamba
Nthawi zambiri, iyenera kuyikidwa pa symmetry ndege kuti muchepetse chiwopsezo chokulirapo.Mwachitsanzo, pazinthu za elliptical, gawo logawanika lili pamtunda wautali, ndipo pazinthu zazikulu, zimadutsa pakati.
Cavity pamwamba
Zinthu za PE ziyenera kukhala zowawa pang'ono, ndipo pamwamba pa mchenga wonyezimira ndi bwino kutulutsa mpweya;Pakuwomba mapulasitiki ena (monga ABS, PS, POM, PMMA, NYLON, ndi zina zotero), nkhungu nthawi zambiri sizingapukutidwe ndi mchenga, ndipo utsiwu ukhoza kupangidwa pagawo la nkhungu, kapena utsi. dzenje akhoza kupangidwa pa nkhungu patsekeke, ndi awiri a dzenje utsi pa wamba nkhungu patsekeke φ 0.1 ~ φ 0.3, kutalika 0.5 ~ 1.5mm.
Cavity kukula
Mlingo wa shrinkage wa pulasitiki uyenera kuganiziridwa pakupanga kukula kwa patsekeke.Kuti mudziwe zambiri, chonde onani kuchulukirachulukira kwa pulasitiki.
Mphepete mwa nyanja ndi m'mphepete mwa nyanja
Nthawi zambiri, popangira mapulasitiki opangira uinjiniya ndi mapulasitiki olimba, m'mphepete mwake muyenera kupangidwa ndi zinthu zokhala ndi kukana kwabwino, monga mkuwa wa beryllium, chitsulo chosapanga dzimbiri, etc. .
Mphepete mwa kudula iyenera kusankhidwa ndi kukula koyenera.Ngati ndi yaying'ono kwambiri, imachepetsa mphamvu ya mgwirizano.Ngati ndi lalikulu kwambiri, silingadulidwe ndipo nsonga yotsekera pamtunda ndi yayikulu.Komabe, nsonga yamchira imatsegulidwa pansi pa nsonga yodula, ndipo nsonga ya mchira imapangidwa kuti ikhale yophatikizidwa.Podula, pang'ono kusungunuka kungathe kufinyidwa mu mgwirizano, motero kumapangitsa mphamvu ya mgwirizano.
Jekiseni kuwomba nkhungu
Kapangidwe kake ndi kosiyana ndi kuwombera kwa extrusion.Kusiyanitsa kwakukulu ndikuti nkhungu ya jekeseni sifunika kudula m'mphepete ndi poyambira.Mapangidwe opanda kanthu a gawo lowombera jekeseni ndi ofunika kwambiri, omwe amakhudza mwachindunji ubwino wa mankhwala omalizidwa.
Jekiseni nkhungu - parison mapangidwe mfundo
1. Utali, m'mimba mwake ndi kutalika ≤ 10/1
2. Kuwomba kukulitsa chiŵerengero cha 3/1~4/1 (chiyerekezo cha kukula kwa mankhwala ndi kukula kwa parison)
3. Khoma makulidwe 2 ~ 5.0mm
4. Malingana ndi mawonekedwe a mankhwalawo, makulidwe a khoma ndi aakulu pamene chiŵerengero chowomba chimakhala chachikulu, ndi chochepa kwambiri pamene chiŵerengero chowomba chimakhala chaching'ono.
5. Pazitsulo zozungulira zomwe zimakhala ndi chiŵerengero cha ellipse choposa 2/1, ndodo yapakati iyenera kupangidwa ngati ellipse.Pazinthu zozungulira zokhala ndi chiŵerengero cha ellipse zosakwana 2/1, ndodo yozungulira imatha kupanga chidebe cha ellipse.
Kuwombera ndodo
Mapangidwe a ndodo yowomba mpweya amatsimikiziridwa molingana ndi mawonekedwe a nkhungu ndi zofunikira za mankhwala.Nthawi zambiri, kusankha kwa dzenje lapakati pa ndodo yotengera mpweya ndi:
L<1: aperture φ one point five
4> L>1: pobowo φ mfundo zisanu ndi imodzi
200>L>4: pobowola φ 12.5 (L: voliyumu, unit: lita)
Kuthamanga kwa mpweya wa pulasitiki wamba wowomba
