Inkqubo yokuphosa yentsimbi engwevu ibandakanya izinto ezintathu ezaziwa ngokuba “ziinto ezintathu” kwishishini lokuphosa: intsimbi elungileyo, isanti elungileyo, kunye nenkqubo elungileyo.Inkqubo yokuphosa yenye yezinto ezintathu eziphambili, ecaleni komgangatho wentsimbi kunye nomgangatho wesanti, ezimisela umgangatho wokusaswa.Inkqubo ibandakanya ukudala isikhunta esivela kwimodeli esantini, kwaye emva koko ugalela intsimbi etyhidiweyo kwi-mold ukudala ukuphosa.
Inkqubo yokuphosa ibandakanya amacandelo alandelayo:
1. Isitya sokugalela: Apha kulapho intsimbi enyibilikisiweyo ingena khona kumngundo.Ukuqinisekisa ukuhambelana kokuthulula kunye nokususa nayiphi na into engcolileyo kwintsimbi etyhidiweyo, ngokuqhelekileyo kukho isitya sokuqokelela i-slag ekupheleni kwesitya sokuthulula.Ngqo ngaphantsi kwesitya sokugalela yi-sprue.
2. Imbaleki: Le yindawo ethe tyaba yesixokelelwano sokutyhida apho intsimbi enyibilikisiweyo ihamba isuka kwispreyi ukuya kumgodi wokungunda.
3. Isango: Le yindawo apho intsimbi etyhidiweyo ingena kumngxuma wokungunda isuka kwimbaleki.Ngokuqhelekileyo kubizwa ngokuba "yisango" ekuphoseni.4. Imbobo: Le yimingxuma ekungundo evumela umoya ukuba uphume njengoko intsimbi enyibilikisiweyo igcwalisa ukungunda.Ukuba ukungunda kwesanti kunokungena kakuhle, imingxuma yokuvula idla ngokungeyomfuneko.
5. IRiser: Eli lijelo elisetyenziselwa ukondla isakhelo njengoko iphola kwaye icutheka.Izikhuphukeli zisetyenziselwa ukuqinisekisa ukuba ukuphosa akukho voids okanye imingxuma ecuthekayo.
Amanqaku aphambili omawaqwalaselwe xa usasaza aquka:
1. I-orientation ye-mold: Umphezulu owenziwe ngomatshini wokuphosa kufuneka ube phantsi kwe-mold ukunciphisa inani le-shrinkage cavities kwimveliso yokugqibela.
2. Indlela yokuthulula: Kukho iindlela ezimbini eziphambili zokuthulula - ukugalela phezulu, apho intsimbi etyhidiweyo igalelwe ukusuka phezulu kwi-mold, kunye nokuthulula ngaphantsi, apho i-mold igcwele ukusuka ngaphantsi okanye phakathi.
3. Ukuma kwesango: Ekubeni intsimbi enyibilikisiweyo iqina ngokukhawuleza, kubalulekile ukubeka isango kwindawo eya kuqinisekisa ukuhamba ngokufanelekileyo kuzo zonke iindawo zokungunda.Oku kubaluleke kakhulu kumacandelo angqingqwa aneendonga zokusasa.Inani kunye nokumila kwamasango kufuneka kuqwalaselwe.
4. Uhlobo lwesango: Kukho iintlobo ezimbini eziphambili zamasango - i-triangular kunye ne-trapezoidal.Amasango angama-triangular kulula ukwenza, ngelixa amasango e-trapezoidal athintela i-slag ekungeneni kwi-mold.
5. Ummandla onxulumeneyo onqamlezileyo wesprue, imbaleki, kunye nesango: NgokukaGqr. R. Lehmann, ummandla onqamlezileyo wesprue, imbaleki, kunye nesango kufuneka zibe kumlinganiselo A:B:C=1:2 :4.Lo mlinganiselo wenzelwe ukuvumela intsimbi etyhidiweyo ukuba ihambe kakuhle kwinkqubo ngaphandle kokubambisa i-slag okanye ezinye izinto ezingcolileyo kwi-casting.
Uyilo lwenkqubo yokuphosa nayo yinto ebalulekileyo yokuqwalaselwa.Umzantsi we-sprue kunye nesiphelo sembaleki kufuneka zombini zisondezwe ukunciphisa isiphithiphithi xa isinyithi esinyibilikisiweyo sigalelwa kumngundo.Ixesha elithathiweyo lokugalela libalulekile.
