Iyo yekukanda simbi yegrey inosanganisira zvinhu zvitatu zvinozivikanwa se "matatu musts" muindasitiri yekukanda: simbi yakanaka, jecha rakanaka, uye maitiro akanaka. Maitiro ekukanda ndechimwe chezvinhu zvitatu zvikuru, padivi pemhando yesimbi uye jecha remhando, izvo zvinotarisa kunaka kwekukandwa. Maitiro acho anosanganisira kugadzira mold kubva kune modhi mujecha, uye nekudururira simbi yakanyungudutswa muforoma kugadzira kukanda.
The casting process inosanganisira zvinotevera zvikamu:
1. Bheseni rekudira: Apa ndipo panopinda simbi yakanyungudutswa muforoma. Kuti uve nechokwadi chekuenderana kwekudurura uye kubvisa chero tsvina kubva musimbi yakanyungudutswa, kazhinji pane bheseni rekuunganidza slag pamagumo ekudururira ndiro. Pazasi pebheseni rekudira ndiro sprue.
2. Runner: Iyi ndiyo nzvimbo yakachinjika yegadziriro yekukandira uko simbi yakanyunguduka inoyerera kubva musprue ichienda kugomba rekuumbwa.
3. Gedhi: Iyi ndiyo nzvimbo iyo simbi yakanyunguduka inopinda mugomba reforoma kubva kumumhanyi. Inowanzo kunzi "gedhi" mukukanda. 4. Mhepo: Aya maburi ari muforoma anoita kuti mhepo ibude sezvo iron yakanyunguduka inozadza chakuvhe. Kana mold yejecha iine kupenya kwakanaka, mavhavha kazhinji haafanirwe.
5. Riser: Iyi inzira inoshandiswa kudyisa kukanda painotonhora nekuderera. Risers anoshandiswa kuona kuti kukanda hakuna voids kana shrinkage cavities.
Zvinhu zvakakosha zvekufunga nezvazvo pakukanda zvinosanganisira:
1. Mamiriro emuumbi: Iyo yakagadzirwa nemichina yekukanda inofanira kunge iri pazasi pe mold kuderedza nhamba ye shrinkage cavities muchigadzirwa chekupedzisira.
2. Nzira yekudurura: Kune nzira mbiri huru dzekudira - kudira kwepamusoro, uko simbi yakanyungudutswa inodururwa kubva pamusoro pemuumbi, uye pasi ichidira, apo mold inozadzwa kubva pasi kana pakati.
3. Kumisikidzwa kwegedhi: Sezvo simbi yakanyungudutswa ichikurumidza kuoma, zvakakosha kuisa gedhi panzvimbo inoita kuti inyatsoyerera munzvimbo dzese dzeforoma. Izvi zvinonyanya kukosha muzvikamu zvakakora-masvingo zvekukanda. Nhamba uye chimiro chemagedhi zvinofanirawo kuonekwa.
4. Rudzi rwegedhi: Kune marudzi maviri makuru emagedhi - triangular uye trapezoidal. Triangular magedhi ari nyore kugadzira, nepo trapezoidal magedhi anodzivirira slag kupinda mu mold.
5. Inoenderana nepakati-chikamu nzvimbo yesprue, mumhanyi, uye gedhi: Maererano naDr. R. Lehmann, nzvimbo yakachinjika yesprue, mumhanyi, uye gedhi inofanira kuva mureshiyo A:B:C=1:2 :4. Chiyero ichi chakagadzirirwa kubvumira simbi yakanyungudutswa kuti ifambe zvakanaka kuburikidza nehurongwa pasina kuteya slag kana kumwe kusvibiswa mukukanda.
Iyo dhizaini yekukanda system zvakare yakakosha kufunga. Pazasi pesprue nemagumo emumhanyi zvese zvinofanirwa kutenderedzwa kuderedza kusagadzikana kana simbi yakanyungudutswa ichidirwa muforoma. Nguva inotorwa yekudira yakakoshawo.
