Njira Yoponyera Mold Shell

Njira yopangira chipolopolo-mold imadziwikanso ngati njira yopangira zipolopolo. Ndi njira yotsika mtengo yopangira nkhungu yomwe imagwiritsa ntchito mchenga wokutidwa ndi utomoni kupanga nkhungu. Popanga chipolopolo cha nkhungu, nkhungu imapangidwa ngati chipolopolo. Nkhungu yopyapyala kapena yopanda pake imagwiritsidwa ntchito kuti kulemera kwa nkhungu kukhale kochepa komanso kugwira nkhungu kumakhala kosavuta.

Kupanga nkhungu yopyapyala, utomoni wa phenolic wokhala ndi mchenga wocheperako wa silika umagwiritsidwa ntchito ngati nkhungu. Pakupanga chipolopolo-nkhungu kuponyera kumafuna kugwiritsa ntchito chitsanzo zitsulo, uvuni, mchenga-utomoni osakaniza, dambo bokosi ndi chitsulo chosungunuka.Kuponyedwa kwa chipolopolo cha nkhunguamalola ntchito zonse zitsulo achitsulo ndi sanali achitsulo, ambiri ntchito zitsulo zosungunuka ndichitsulo chotuwa, ductile cast iron, carbon steel,aloyi chitsulo, zitsulo zosapanga dzimbiri, zitsulo za aluminiyamu ndi zosakaniza zamkuwa.

Masitepe a Shell Mold Casting

1. Kupanga kwachitsanzo - Chitsulo chazitsulo ziwiri chimapangidwa mu mawonekedwe ofunikira omwe amafunikira.
2. Kulengedwa kwa nkhungu - Choyamba, theka lililonse lachitsanzo limatenthedwa mpaka 175-370 ° C ndipo limakutidwa ndi lubricant kuti likhale losavuta kusiyana ndi chitsanzo chomwe chinapangidwa. Kenako, chitsanzo chotenthetsera chimangiriridwa ku bokosi lotayirira. Bokosi lotayiralo limatembenuzidwa, zomwe zimapangitsa kuti mchenga wa utomoni wosakaniza uvale patani. Chitsanzo chotenthedwa chimachiritsa pang'onopang'ono chosakaniza, chomwe tsopano chimapanga chipolopolo kuzungulira chitsanzocho. Theka lililonse la theka ndi chipolopolo chozungulira chimachiritsidwa kuti chitsirizidwe mu uvuni ndiyeno chipolopolocho chimatulutsidwa kuchokera patani.
3. Kumanga nkhungu - Mahalo awiri a zigoba amalumikizidwa palimodzi ndikumangirira bwino kuti apange nkhungu yonse. Ngati ma cores akufunika, amalowetsedwa asanatseke nkhungu. Kenako nkhungu ya chigobacho imayikidwa mu botolo ndi kuthandizidwa ndi chinthu chothandizira.
4. Kuthira - Chikombole chimangiriridwa bwino pamene chitsulo chosungunula chimatsanuliridwa kuchokera ku ladle kupita kumalo olowera ndikudzaza nkhungu.
5. Kuzizira - Pambuyo podzaza nkhungu, chitsulo chosungunula chimaloledwa kuziziritsa ndi kukhazikika mu mawonekedwe a kuponyedwa kofunikira.
6. Kuchotsa kutaya - Pambuyo pa chitsulo chosungunula chokhazikika, nkhungu imasweka ndipo kuponyedwa kumachotsedwa. Kudula ndi kuyeretsa kumachitidwa kuti achotse chitsulo chilichonse chowonjezera pazakudya ndikulekanitsa tinthu tating'ono ta mchenga ku nkhungu.

Mawonekedwe a Shell Molding process:

• • Mu chipolopolo akamaumba ndondomeko makulidwe ndi kulemera kwa nkhungu ndi zochepa.
• • Kupanga mlingo wa nkhungu chipolopolo ndi mkulu kwambiri.
• • Chifukwa cha kuchepa kwa nkhungu, muyenera kugwiritsa ntchito chokwera.
• • Ndi zothandiza pa ntchito zozungulira ndi symmetrical okha.
• • Maonekedwe ovuta kwambiri sangapangidwe pogwiritsa ntchito njira yopangira nkhungu.
• • Njirayi imapanga mawonedwe olondola kwambiri poyerekeza ndi enaMchenga kuponyera ndondomeko.
• • Makona apansi angagwiritsidwe ntchito.
