M'kati mwamakinandi kupanga jekeseni akamaumba, ndi dongosolo Integrated, amene sangathe kulekana.
Pakuumba jekeseni, dongosolo la gating limatanthawuza gawo la wothamanga pulasitiki isanalowe m'mimba kuchokera pamphuno, kuphatikizapo wothamanga wamkulu, zozizira zakuthupi, wothamanga ndi chipata, ndi zina zotero.
Dongosolo lakutsanulira limatchedwanso dongosolo lothamanga.Ndi njira zoperekera chakudya zomwe zimatsogolera kusungunuka kwa pulasitiki kuchokera pamphuno ya makina a jakisoni kupita kumimba.Nthawi zambiri zimakhala ndi wothamanga wamkulu, wothamanga, chipata ndi malo ozizira.Zimagwirizana mwachindunji ndi khalidwe loumba komanso kupanga bwino kwa zinthu zapulasitiki.
Injection Mold Main Road:
Ndi ndime mu nkhungu zikugwirizana nozzle wa jekeseni akamaumba makina kwa wothamanga kapena patsekeke.Pamwamba pa sprue ndi concave kugwirizana ndi nozzle.M'mimba mwake wa cholowera chothamanga chachikulu chizikhala chokulirapo pang'ono kuposa m'mimba mwake (0.8mm) kupewa kusefukira ndikuletsa ziwirizo kutsekedwa chifukwa cholumikizana molakwika.Kutalika kwa cholowera kumatengera kukula kwa chinthucho, nthawi zambiri 4-8mm.Kutalika kwa wothamanga wamkulu kuyenera kukulitsidwa mkati mwa ngodya ya 3 ° mpaka 5 ° kuti athe kugwetsa wothamanga.
Cold Slug:
Ndi patsekeke kumapeto kwa wothamanga waukulu kuti msampha zinthu ozizira kwaiye pakati jekeseni awiri kumapeto kwa nozzle kuteteza kutsekeka kwa wothamanga kapena chipata.Zinthu zozizira zikasakanizidwa mumtsempha, kupsinjika kwamkati kumatha kuchitika muzinthu zopangidwa.Kutalika kwa dzenje lozizira la slug ndi pafupifupi 8-10mm ndipo kuya ndi 6mm.Pofuna kuwongolera, pansi nthawi zambiri amanyamulidwa ndi ndodo yoboola.Pamwamba pa ndodo yovundukula iyenera kupangidwa mu mawonekedwe a zigzag mbedza kapena kukhazikitsidwa ndi poyambira, kotero kuti sprue akhoza kuzulidwa bwino pamene akugwetsa.
Shunt:
Ndilo njira yolumikizira njira yayikulu komanso pabowo lililonse mu nkhungu yamitundu yambiri.Pofuna kusungunula kudzaza mabowo pa liwiro lomwelo, makonzedwe a othamanga pa nkhungu ayenera kukhala ofanana ndi ofanana.Maonekedwe ndi kukula kwa gawo la mtanda wa wothamanga zimakhudza kuyenda kwa pulasitiki kusungunuka, kugwetsa mankhwala ndi zovuta kupanga nkhungu.Ngati kutuluka kwa zinthu zomwezo zimagwiritsidwa ntchito, kukana kwa njira yothamanga ndi gawo lozungulira ndilochepa kwambiri.Komabe, chifukwa malo enieni a cylindrical wothamanga ndi ochepa, sizili bwino kuti kuziziritsa kwa wothamanga kusakhale kofunikira, ndipo wothamanga ayenera kutsegulidwa pazigawo ziwiri za nkhungu, zomwe zimakhala zogwira ntchito komanso zovuta kuzigwirizanitsa.Choncho, othamanga a trapezoidal kapena semicircular cross-section nthawi zambiri amagwiritsidwa ntchito, ndipo amatsegulidwa pa theka la nkhungu ndi ndodo yovula.Malo othamanga ayenera kupukutidwa kuti achepetse kukana kwakuyenda ndikupereka liwiro lodzaza mwachangu.Kukula kwa wothamanga kumadalira mtundu wa pulasitiki, kukula ndi makulidwe a mankhwala.
Kwa ma thermoplastics ambiri, kutalika kwa gawo la othamanga sikudutsa 8mm, zowonjezera-zazikulu zimatha kufika 10-12mm, ndi zowonjezera zazing'ono 2-3mm.Pachiyambi chokwaniritsa zofunikira, malo ozungulira ayenera kuchepetsedwa momwe angathere kuti awonjezere zinyalala za wothamanga ndikuwonjezera nthawi yozizira.
