Mukugadzirwa kwemotokari dzinofa-kukanda molds, kusarudzwa kwechinzvimbo chegedhi kunowanzo kuganhurirwa nezvinhu zvakaita semhando yealloy, chimiro chekukanda uye chimiro, shanduko yemadziro emadziro, shrinkage deformation, mhando yemuchina (yakatwasuka kana yakatwasuka), uye kukanda zvinodiwa zvekushandisa.Naizvozvo, kune zvikamu zvekufa-kandira, iyo yakanakira gedhi chinzvimbo haawanzo.Pakati pezvinhu izvi zvinoda kufungwa nezvazvo, nzvimbo yegedhi inogona kusarudzwa chete nekusangana nezvinodiwa zvikuru, kunyanya kune zvimwe zvinodikanwa.
Nzvimbo yegedhi yemotokari inofa-yekukanda molds inotanga kuganhurirwa nechimiro chezvikamu zvekukanda-fa, uchifungawo zvimwe zvinhu.
(1) Nzvimbo yegedhi inofanirwa kutorwa panzvimbo iyo iyo simbi yekuzadza mvura nzira Z ipfupi uye chinhambwe chezvikamu zvakasiyana zvegomba remuvhu chiri padyo sezvinobvira kudzikisa tortuosity yenzira yekuzadza uye kudzivirira kutsauka kwakanyanya.Nokudaro, zvinokurudzirwa kushandisa gedhi repakati zvakanyanya sezvinobvira.
(2) Kuisa chinzvimbo chegedhi remota inofa-yekukanda mold paZ-gobvu chikamu chemudhuri wekufa-casting kunobatsira pakufambiswa kweiyo Z-yekupedzisira kudzvanywa.Panguva imwecheteyo, gedhi riri munzvimbo yakakora yemadziro, richisiya nzvimbo yekuwedzera kwehupamhi hwegedhi remukati.
(3) Nzvimbo yegedhi inofanirwa kuona kuti kugoverwa kwenzvimbo yekushisa kwegomba kunosangana nezvinodiwa, uye kuyedza kuzadzisa mamiriro ekuzadza kwesimbi yemvura kuyerera kusvika kumagumo eZ.
(4) Nzvimbo yegedhi remotokari kufa-casting mold inotorwa panzvimbo iyo mvura yesimbi inopinda mugomba remuvhu pasina mavhuvhu uye kubuda kunotsvedzerera, izvo zvinoita kuti gasi ribviswe mugomba rekuumbwa.Muchiito chekugadzira, zvakanyanya kuoma kubvisa magasi ese, asi iko kutarisisa kwekugadzira kuedza kubvisa gasi rakawanda sezvinobvira zvichienderana nechimiro chekukanda.Iyo nyaya yekupopota inofanirwa kutariswa zvakanyanya kune castings ine mhepo inomanikidza zvinodiwa.
(5) Kune bhokisi rakaumbwa castings, iyo gedhi nzvimbo inogona kuiswa mukati meiyo fungidziro yemhando yekukanda.Kana gedhi rimwe chete rakanyatsozadzwa, hapana chikonzero chekushandisa magedhi akawanda.
(6) Nzvimbo yegedhi remotokari inofa-yekukanda mold inofanirwa kunge iri padyo sezvinobvira kunzvimbo iyo kuyerera kwesimbi kusingabatike zvakananga pakati, uye inofanirwa kudzivirirwa kuti iite kuti simbi inoyerera ichikanganisa musimboti (kana madziro). )Nokuti mushure mekurova nheyo, simba rekinetic resimbi yakanyungudutswa rinopera nechisimba, uye zviri nyorewo kuumba madonhwe akapararira anosanganiswa nemhepo, zvichiita kuti kuwedzera kwekukanda kunokanganisa.Mushure mokunge musimboti waparara, unobereka mold sticking, uye mumatambudziko akaoma, nzvimbo yakasvibiswa inoumba kuora mwoyo, kunokanganisa kuderedzwa kwekukanda.
(7) Nzvimbo yegedhi inofanira kuiswa panzvimbo iyo iri nyore kubvisa kana kurova gedhi mushure mokunge kuumbwa kwaitwa.
(8) Zvekufa-kukanda zvikamu zvinoda kusimba kwemhepo kana kusatendera kuvepo kwepores, mumhanyi wemukati anofanirwa kuiswa panzvimbo iyo simbi yemvura Z inogona kuchengetedza kudzvanywa nguva dzese.
