China grey cast ironshell mold casting productsneOEM tsika uye CNC machining masevhisi. Diverse metal giredhi iripo.
Kugadzira simbi uye simbi inokandwa sekudhirowa kwevatengi ndicho chikamu chedu chakakosha chebasa rekukanda asi kwete sevhisi yedu chete. Chaizvoizvo, isu tinopa zvachose imwe-stop-solution simbi yekukanda masevhisi ane akasiyana kukosha akawedzera masevhisi anosanganisira kukanda dhizaini, CNC chaiyo machining, kupisa kupisa, kupera kwepasi, kuunganidza, kurongedza, kutumira ... nezvimwe.
Usati wagadzira mold uye core, jecha rakaputirwa rakafukidzwa nefirimu resin yakasimba pamusoro pezvikamu zvejecha. Theshell mold castingYakagadzirwa kuita jecha rakavharidzirwa nekushandisa thermoplastic phenolic resin plus latent curring agent (senge urotropine) uye lubricant (senge calcium stearate) kuburikidza neimwe nzira yekupfekedza. Kana jecha rakaputirwa richipisa, resin yakavharwa pamusoro pezvikamu zvejecha inonyunguduka. Pasi pechiito cheboka re methylene rakasvibiswa neMaltropine, resin yakanyungudutswa inokurumidza kushanduka kubva kune mutsara wakarongeka kusvika kune infusible body structure kuitira kuti jecha rakaputirwa rive rakasimba uye riumbwe. Pamusoro peiyo yakajairika yakaoma granular fomu yejecha rakavharwa, kune zvakare rakanyorova uye viscous rakavharwa jecha.
▶ Kukandwa kwejecha kwakavharwa kune zvinotevera
1) Iine akakodzera simba rekuita. Inogona kusangana nezvinodiwa kune yakakwirira-simba shell core jecha, yepakati-simba rinopisa-bhokisi jecha, uye pasi-simba risina-ferrous alloy jecha.
2) Yakanakisa fluidity, yakanaka moldability yejecha musimboti uye yakajeka ratidziro, iyo inogona kuburitsa yakanyanya kuoma jecha cores, senge jecha remvura jecha cores senge cylinder misoro nemitumbi yemuchina.
3) Hunhu hwepamusoro hwejecha core yakanaka, compact uye haina kusununguka. Kunyangwe kana kushoma kana kusavharwa kwakaiswa, zvirinani zvemhando yepamusoro zvekukanda zvinogona kuwanikwa. The dimensional kunyatsoita castings anogona kusvika CT7-CT8, uye pamusoro roughness Ra anogona kusvika 6.3-12.5μm.
4) Kudonha kwakanaka, kunobatsira pakukanda kuchenesa nekuvandudza kuita kwechigadzirwa
5) Iyo jecha musimboti haisi nyore kutora unyoro, uye kusimba kwekugara kwenguva refu hakusi nyore kuderera, iyo inobatsira kuchengetedza, kutakura uye kushandisa.
▶ Magadzirirwo ekugadzira akavharidzirwa jecha mold (musimboti) kugadzira ganda rekukanda kukanda:
1. Nzira yekutanga yekugadzira yakavharwa jecha mold (core) ndeiyi: flip kana kuputira jecha → crust → kuburitsa jecha → kuoma → musimboti ( mold) zvichingodaro.
1) Shandura kana kuputira jecha. Kureva kuti, jecha rakaputirwa rinodururwa paganda mold kana kupeperetswa mukati mebhokisi repakati kugadzira goko kana goko repakati.
2) Encrustation. Ukobvu hweganda reganda rinodzorwa nekugadzirisa kupisa kwekupisa uye kubata nguva.
3) Kubuda kwejecha. Rongedza mold uye bhokisi repakati kuita kuti jecha risina kuvharwa ridonhe kubva pagoko rinopisa, woriunganidza kuti rizoshandiswazve. Kuti zvive nyore kubvisa jecha risina kunyunguduka rakaputirwa, kana zvichidikanwa, nzira yemagetsi yekuzunungusa kumashure uye mberi inogona kugamuchirwa.
4) Kuomesa. Mumamiriro ekupisa, kuitira kuti kukora kwegomba kuve yunifomu, ita kuti ibatane nepamusoro peganda rinopisa mukati meimwe nguva yekuwedzera kuoma.
5) Tora musimboti. Tora iyo yakaomeswa goko chimiro uye shell core kunze kwe mold uye musimboti bhokisi.
