Shell Mold Casting

Shell Mold Casting Foundry

Kuponyedwa kwa zipolopolo kumatchedwanso kuti pre- TACHIMATA utomoni kuponya mchenga njira, otentha chipolopolo kuponya kuponyera kapena pachimake kuponyera. Zomwe zimapangidwira kwambiri ndi mchenga wa phenolic resin, womwe umakhala wokwera mtengo kuposamchenga wobiriwirandi mchenga wa furan resin. Kuphatikiza apo, mchengawu sungagwiritsidwenso ntchito.

Zida zopangira zipolopolo zimakhala ndi mtengo wokwera pang'ono kuposakuponya mchenga. Komabe, azipolopolo akamaumba kuponyera zigawoali ndi zabwino zambiri monga kulolerana kocheperako, mawonekedwe abwino apamwamba komanso zolakwika zochepa zoponya.

Asanapange nkhungu ndi pachimake, mchenga wokutira waphimbidwa ndi filimu yolimba ya utomoni pamwamba pa mchenga. Mchenga wokutidwa umatchedwanso chipolopolo (pachimake) mchenga. Njira yaukadaulo ndikusakaniza mwamakani mtengo wa ufa wa thermosetting phenolic ndi mchenga wosaphika ndikuulimbitsa ukatenthedwa. Apangidwa kukhala mchenga wokutidwa pogwiritsa ntchito thermoplastic phenolic resin plus latent curing agent (monga urotropine) ndi lubricant (monga calcium stearate) kudzera munjira zina zokutira.

Mchenga wokutidwa ukatenthedwa, utomoni womwe umakutidwa pamwamba pa mchengawo umasungunuka. Pansi pa zochita za gulu la methylene lomwe limavunda ndi Maltropine, utomoni wosungunuka umasintha kuchokera ku mzere wozungulira kupita ku thupi losasunthika kotero kuti mchenga wophimbidwa umalimba ndikupangidwa. Kuphatikiza pa mchenga wowuma wouma, palinso mchenga wonyowa komanso wokutidwa ndi viscous.

Mukasakaniza mchenga wapachiyambi (kapena mchenga wobwezeretsedwa), utomoni wamadzimadzi ndi chothandizira chamadzimadzi mofanana, ndikuzidzaza mu bokosi lalikulu (kapena bokosi la mchenga), ndiyeno mumangirire kuti liwumitse mu nkhungu kapena nkhungu mu bokosi lalikulu (kapena mchenga bokosi). ) pa kutentha kwa chipinda, nkhungu yoponyera kapena chitsulo choponyera chinapangidwa, chomwe chimatchedwa self-hardening cold-core box modeling (pachimake), kapena njira yodzipangira yokha (core). Njira yodziumitsa yokha imatha kugawidwa mu acid-catalyzed furan resin ndi phenolic resin mchenga kudziletsa njira, urethane resin mchenga kudziletsa kuumitsa njira ndi phenolic monoester kudziletsa kuumitsa njira.

Njira Zopangira Zipolopolo za Mold

✔ Kupanga Zitsulo.Mchenga wophimbidwa utomoni uyenera kutenthedwa pamapataniwo, chifukwa chake mawonekedwe achitsulo ndi chida chofunikira chopangira zipolopolo.
✔ Kupanga Nkhungu Yamchenga Yokutira kale.Pambuyo poyika zitsulo pamakina omangira, mchenga wa utomoni wophimbidwa kale udzawomberedwa pamapangidwewo, ndipo mutatha kutentha, kupaka utomoni kumasungunuka, kenako nkhungu zamchenga zimakhala chipolopolo cholimba cha mchenga ndi ma cores.
✔ Kusungunula Chitsulo cha Cast.Pogwiritsa ntchito ng'anjo zopangira, zidazo zimasungunuka kukhala madzi, ndiye kuti mankhwala achitsulo chamadzimadzi amayenera kufufuzidwa kuti agwirizane ndi manambala ndi maperesenti ofunikira.
✔ Kuthira Chitsulo.Chitsulo chosungunuka chikakwaniritsa zofunikira, chidzatsanuliridwa mu nkhungu za chipolopolo. Kutengera ndi zilembo zosiyanasiyana zamapangidwe oponya, zipolopolozo zimakwiriridwa mumchenga wobiriwira kapena zowunjikiridwa ndi zigawo.
✔ Kuwombera Kuwombera, Kupera ndi Kuyeretsa.Pambuyo pozizira ndi kulimba kwa zoponyera, zokwera, zitseko kapena zitsulo zowonjezera ziyenera kudulidwa ndikuchotsedwa. Kenako zitsulozo zimatsukidwa ndi zida zokopera mchenga kapena makina owombera. Pambuyo pogaya mutu wa gating ndi mizere yolekanitsa, mbali zomalizidwa zoponyedwa zimabwera, kudikirira njira zina ngati zikufunika.

Chipolopolo cha Chipolopolo cha Ductile Iron Castings

Ubwino wa Shell Mold Casting

1) Ili ndi magwiridwe antchito oyenera. Ikhoza kukwaniritsa zofunikira pa mchenga wa chipolopolo champhamvu kwambiri, mchenga wa bokosi lamphamvu lapakati, ndi mchenga wa alloy wopanda mphamvu zochepa.
2) Kusungunuka kwabwino kwambiri, kuumbika bwino kwa pachimake cha mchenga ndi ndondomeko yomveka bwino, yomwe imatha kupanga mchenga wovuta kwambiri, monga mchenga wa jekete lamadzi monga mitu ya silinda ndi matupi a makina.
3) Ubwino wapakatikati pa mchenga ndi wabwino, wophatikizika komanso wosamasuka. Ngakhale zokutira zocheperako kapena zosagwiritsidwa ntchito, zopanga zapamwamba zitha kupezeka. The dimensional kulondola kwa castings akhoza kufika kalasi kuyambira CT 7 - CT 8, ndi pamwamba roughness Ra akhoza kufika 6.3 - 12.5 μm.
4) Kuwonongeka kwabwino, komwe kumathandizira kuyeretsa ndikuwongolera magwiridwe antchito
5) Mchenga wapakati siwosavuta kuyamwa chinyezi, ndipo mphamvu yosungiramo nthawi yayitali sivuta kuchepa, yomwe imathandizira kusungirako, kuyendetsa ndi kugwiritsa ntchito.
