Compression Molding Njira ndi Compress Molding Equipment

Chida chachikulu chopangira kuumba ndi makina osindikizira a hydraulic.Udindo wa makina osindikizira a hydraulic pakukankhira ndikukakamiza pulasitiki kudzera mu nkhungu, kutsegula nkhungu ndikutulutsa chinthucho.

Kumangirira kumagwiritsidwa ntchito makamaka popanga mapulasitiki a thermosetting.Kwa thermoplastics, chifukwa chakufunika kokonzekera kulibe kanthu pasadakhale, imayenera kutenthedwa ndi kuziziritsidwa mosinthanasinthana, kotero kuti nthawi yopanga ndi yayitali, kupanga bwino kumakhala kochepa, komanso kugwiritsa ntchito mphamvu kumakhala kwakukulu.Kuphatikiza apo, zinthu zokhala ndi mawonekedwe ovuta komanso makulidwe olondola kwambiri sangathe kukanikizidwa.Chifukwa chake chizolowezi chofika pakuumba jekeseni wochuluka.

Themakina opangira ma compression(kanikiza mwachidule) chomwe chimagwiritsidwa ntchito poumba ndi chosindikizira cha hydraulic.Kukakamiza kwake kumawonetsedwa ndi matani odziwika, nthawi zambiri, pali 40t ﹑ 630t ﹑ 100t ﹑ 160t ﹑ 200t ﹑ 250t ﹑ 400t ﹑ 500t mndandanda wa makina osindikizira.Pali matani oposa 1,000 a makina osindikizira osiyanasiyana.Zomwe zili m'mawu atolankhani zimaphatikizapo matani ogwiritsira ntchito, ejection tonnage, kukula kwa platen kukonza kufa, ndi mikwingwirima ya piston ndi pistoni yotulutsa, ndi zina zambiri. .Zigawo zing'onozing'ono zingagwiritse ntchito makina osindikizira ozizira (popanda kutentha, madzi ozizira okha) popanga ndi kuziziritsa.Gwiritsani ntchito makina osindikizira otenthetsera kuti muzitha kutenthetsa, zomwe zingapulumutse mphamvu.

Malinga ndi kuchuluka kwa makina osindikizira, makina osindikizira amatha kugawidwa m'mamanja, makina osindikizira a semi-automatic, ndi makina osindikizira okha.Malinga ndi kuchuluka kwa zigawo za mbale yathyathyathya, imatha kugawidwa m'magawo awiri komanso makina osindikizira amitundu yambiri.

Makina osindikizira a hydraulic ndi makina oponderezedwa oyendetsedwa ndi ma hydraulic transmission.Mukakanikiza, pulasitiki imayamba kuwonjezeredwa ku nkhungu yotseguka.Kenaka perekani mafuta opanikizika ku silinda yogwira ntchito.Motsogozedwa ndi mzati, pisitoni ndi mtengo wosunthika zimasunthira pansi (kapena m'mwamba) kutseka nkhungu.Potsirizira pake, mphamvu yopangidwa ndi makina osindikizira a hydraulic imatumizidwa ku nkhungu ndikugwira ntchito pa pulasitiki.

Pulasitiki mkati mwa nkhungu imasungunuka ndi kufewetsa pansi pa kutentha.Nkhungu imadzazidwa ndi kukakamizidwa kuchokera ku makina osindikizira a hydraulic ndipo zochita za mankhwala zimachitika.Kuti muthe kutulutsa chinyezi ndi zina zosasinthika zomwe zimapangidwa panthawi ya condensation ya mapulasitiki ndikuwonetsetsa kuti chinthucho chili bwino, ndikofunikira kuchita mpumulo komanso kutulutsa mpweya.Limbikitsani ndi kukonza nthawi yomweyo.Panthawiyi, utomoni mu pulasitiki ukupitirizabe kupangidwa ndi mankhwala.Pambuyo pa nthawi inayake, malo osasunthika komanso osasunthika olimba amapangidwa, ndipo kuumba kolimba kumatsirizika.Nkhungu imatsegulidwa nthawi yomweyo, ndipo mankhwalawa amachotsedwa mu nkhungu.Pambuyo poyeretsa nkhungu, mzere wotsatira wopangira ukhoza kupitilira.

Zitha kuwoneka kuchokera pamwambapa kuti kutentha, kupanikizika, ndi nthawi ndizofunikira kwambiri pakupanga kukangana.Pofuna kupititsa patsogolo zokolola za makina ndi chitetezo ndi kudalirika kwa ntchito, kuthamanga kwa makinawo ndi chinthu chofunika kwambiri chomwe sichinganyalanyazidwe.Chifukwa chake, makina osindikizira apulasitiki a hydraulic omwe amagwiritsidwa ntchito kukanikiza ayenera kukwaniritsa zofunikira izi:

① Kukakamiza kokakamiza kuyenera kukhala kokwanira komanso kosinthika, komanso kumafunikanso kufikira ndikusunga kupanikizika komwe kudakonzedweratu pakapita nthawi.

② Mtsinje wosunthika wa makina osindikizira a hydraulic ukhoza kuyima ndikubwerera nthawi iliyonse ya stroke.Izi ndizofunikira kwambiri pakuyika zisankho, kukanikizatu, kulipira batch, kapena kulephera.

③ Mtengo wosunthika wa makina osindikizira a hydraulic amatha kuwongolera liwiro ndikugwiritsa ntchito kukakamiza kogwira ntchito nthawi iliyonse ya sitiroko.Kukwaniritsa zofunikira za nkhungu zazitali zosiyanasiyana.

Mtsinje wosunthika wa makina osindikizira a hydraulic uyenera kukhala ndi liwiro lothamanga mu sitiroko yopanda kanthu chikombole chachimuna chisanakhudze pulasitiki, kuti afupikitse kuzungulira kwa makinawo, kupititsa patsogolo zokolola zamakina ndikupewa kuchepetsa kapena kuuma kwa kayendedwe ka pulasitiki.Pamene nkhungu yamphongo ikhudza pulasitiki, kuthamanga kwa nkhungu kutsekeka kuyenera kuchepetsedwa.Apo ayi, nkhungu kapena kuyikapo kungawonongeke kapena ufa ukhoza kutsukidwa kuchokera ku nkhungu yachikazi.Panthawi imodzimodziyo, kuchepetsa liwiro kungathenso kuchotsa mpweya mu nkhungu.
