Kusanthula kukhathamiritsa kwa zida ndi zida za aluminium alloy die casting mo

1. Kusankhidwa kwa Die Casting Mold Materials

Pankhani yosankha zida za nkhungu, chisankho chaposachedwa kwambiri ndi chitsulo cha H13, chomwe chimapangidwa pogwiritsa ntchito njira yovuta.Kupyolera mu kutentha kwapamwamba kuzimitsidwa ndi chithandizo cha kutentha, ma carbides muzinthu zachitsulo amapanga kugawa koyenera, ndi kugawa yunifolomu.Pambuyo popanga chithandizo, kuuma kwazinthu zachitsulo kumatha kufika 46-49HRC, zomwe zimathandizira kukana kuvala, kukana dzimbiri, komanso kukana kutopa kwasintha kwambiri.

2. Kukonza Mapangidwe Apangidwe a Die Casting Dies

Kugwiritsa ntchito mamangidwe omveka bwino mu nkhungu zoponya kufa kumatha kutalikitsa moyo wawo wautumiki.

Mwachitsanzo:

① Pachimake chopondapo amatha kuchepetsa mphamvu yomatira yamadzimadzi achitsulo pamwamba pa nkhungu yoponyera kufa;

② Mapangidwe opangira mapasa amatha kuchepetsa kukhudzidwa kwachitsulo chosungunula pachimake chowonda;

③ Kuchulukitsa bwino gawo la mtanda wa ingate kumatha kuwonjezera kuthamanga kwachitsulo chosungunula ndikuchepetsa mphamvu yachitsulo chosungunuka pa nkhungu yoponya;

④ Mapangidwe ophatikizika a kusefukira atha kuchepetsa bwino mapindikidwe a zoponya zakufa ndikuwongolera mawonekedwe a kufa;

⑤ Kuphatikizika kudzachepetsa kuuma kwa pabowo, ndipo izi ziyenera kuganiziridwa pamapangidwe a nkhungu zoponyera kufa;

⑥ Pangani choyikapo pamalo pomwe ming'alu imawonekera nthawi zambiri mu nkhungu yoponya kufa.Pogwiritsa ntchito nkhungu, ngati ming'alu ichitika, nkhungu yonseyo siyenera kusinthidwa.Kungochotsa choyikapocho kumatha kukulitsa moyo wautumiki wa gawo lalikulu la nkhungu yoponya kufa ndikupulumutsa ndalama.
