Kuyilo lwe-automotive die-casting molds, ukhetho lwendawo yesango luhlala lulinganiselwe ngezinto ezifana nohlobo lwe-alloy, isakhiwo sokuphosa kunye nokuma, utshintsho lwendonga, ukuguqulwa kwe-shrinkage, uhlobo lomatshini (oluthe tye okanye oluthe nkqo), kunye neemfuno zokusetyenziswa kokuphosa.Ngoko ke, kwiindawo zokufa, indawo efanelekileyo yesango inqabile.Phakathi kwezi zinto kufuneka ziqwalaselwe, indawo yesango inokumiselwa kuphela ngokuhlangabezana neemfuno eziphambili, ngakumbi kwiimfuno ezizodwa.
Indawo yesango lokubumba i-automotive die-casting molds kuqala inqunyelwe yimo yeendawo zokufa, ngelixa kuqwalaselwa ezinye izinto.
(1) Isikhundla sesango kufuneka sithathwe kwindawo apho inkqubo yokuzalisa ulwelo lwesinyithi i-Z imfutshane kwaye umgama ukuya kwiindawo ezahlukahlukeneyo zombhobho wokungunda usondelene kangangoko kunokwenzeka ukunciphisa ukunyanzeliswa kwendlela yokuzalisa kunye nokuphepha ukuphambuka okugqithisileyo.Ngoko ke, kucetyiswa ukuba usebenzise isango eliphakathi kangangoko kunokwenzeka.
(2) Ukubeka indawo yesango lokungunda kwe-automobile die-casting kwi-Z-thick part of the die-casting wall inceda ukuhanjiswa koxinzelelo lwe-Z-final.Ngelo xesha, isango libekwe kwindawo eludongeni olungqingqwa, lishiya indawo yokunyuka kobunzima besango langaphakathi.
(3) Isikhundla sesango kufuneka siqinisekise ukuba ukuhanjiswa kwendawo yobushushu bomgodi kuyahlangabezana neemfuno zenkqubo, kwaye uzame ukuhlangabezana nemiqathango yokuzaliswa kolwelo lwesinyithi ukuya kwisiphelo esikude se-Z.
(4) Indawo yesango lokungunda kwemoto ithathwa kwindawo apho ulwelo lwesinyithi lungena kumngxuma wokungunda ngaphandle kwe-vortices kwaye umbhobho ogudileyo, onceda ekupheliseni igesi kumgodi wokungunda.Kwimveliso yokuvelisa, kunzima kakhulu ukuphelisa zonke iigesi, kodwa kukuqwalaselwa koyilo lokuzama ukuphelisa igesi eninzi kangangoko ngokwemilo yokuphosa.Umba wokukhupha kufuneka unikwe ingqwalasela ekhethekileyo kwii-castings ezineemfuno zokuqina komoya.
5Ukuba isango elilodwa lizaliswe kakuhle, akukho mfuneko yokusebenzisa amasango amaninzi.
(6) Indawo yesango lokungunda kwemoto kufuneka isondele kangangoko kunokwenzeka kwindawo apho ukuhamba kwesinyithi kungachaphazeli ngokuthe ngqo undoqo, kwaye kufuneka kuphetshwe ukwenza ukuba ukuhamba kwesinyithi kuchaphazele umbindi (okanye udonga). ).Ngenxa yokuba emva kokubetha i-core, amandla e-kinetic yensimbi etyhidiweyo achithwa ngokukhawuleza, kwaye kulula ukwenza amaconsi ahlakaziweyo adibanisa nomoya, okubangelwa ukwanda kweziphene zokuphosa.Emva kokuba i-core ihlanjululwe, ivelisa i-mold sticking, kwaye kwiimeko ezinzima, indawo ekhutshiweyo yenza ukudakumba, okuchaphazela ukuchithwa kwe-casting.
(7) Isikhundla sesango kufuneka sibekwe kwindawo apho kulula ukukhupha okanye ukubethelela isango emva kokuba kwenziwe ukuphosa.
(8) Kwiindawo ezifayo ezifuna ukuxinana komoya okanye zingavumeli ubukho be-pores, imbaleki yangaphakathi kufuneka ibekwe kwindawo apho ulwelo lwesinyithi u-Z lunokugcina uxinzelelo ngamaxesha onke.
