Iphoswa njani iziko lokunyibilikisa lokungeniswa?

Inkqubo yobhedu yobhedu yahlulahlulwe ngokubanzi ibe: ubhedu lwesanti, ubhedu oluchanekileyo, ubhedu oludayayo, ubhedu olubumbayo, njl.njl.

1. Yenza i-molds kunye ne-wax molds kunye nemizobo yokucwangcisa.

2. I-wax mold yenziwa, kwaye ukuhlolwa kufanelekileyo (iifonti, iipatheni, iipateni).

3. Ngokobukhulu obufanelekileyo be-wax mold, ihlelwe ibe yimithi yemithi.

4. Yenza ibrashi eluncedo kunye neneenkcukacha zomngundo we-wax womthi odibeneyo (sebenzisa ibrashi encinci ukuzalisa iifonti kunye neepateni)

5. Xhobisa udaka ngesanti ecikizekileyo, kwaye ufake i-wax mold kwi-emele enodaka ukuze udibanise ngokulinganayo umphezulu we-wax mold. Ukuthambisa kunye nodaka oluthambileyo luyinxalenye ebalulekileyo yokuqinisekisa ukuthambisa okungaphezulu kobhedu. Ukuntywiliselwa ngokuphindaphindiweyo kwesanti ecocekileyo kunye nentlabathi enqabileyo kwiindawo ezininzi kukulungiswa kwemodeli. Inani elincinci le-coagulation yezinto eziluhlaza zifunekayo ukuba zongezwe kwisanti, kwaye ayikwazi ukuba kakhulu. Ukubaluleka kokungunda kweqokobhe kulele ekuqineni kwalo. Nje ukuba iqhekeziwe ngexesha lokusalwa, inkqubo ukusuka kwinaliti yewax ukuya ekwenziweni kobunjwa beqokobhe iya kugqitywa.

6. Beka iqokobhe nge-wax mold ngaphakathi kwitshaneli yonke efakwe kwiziko lokutshisa kwaye uyibeke phezulu, ujike i-port yokugalela ezantsi, kwaye uyiwose. Ukufudumala ngokukhawuleza, ukwenzela ukuba i-wax mold inyibilike ngokuthe ngcembe, ukuze iphume kumngxunya wokuphosa. Le ndawo ayikunyibilikisa kuphela ukungunda kwe-wax ngaphandle kweqokobhe, kodwa ikwadinga ukudibanisa isanti yokubumba iqokobhe kunye ukunyusa ubulukhuni kunye nokomelela kweqokobhe lokungunda. Ngokweqondo lokungunda kweqokobhe kunye nobukhulu bemilo yeqokobhe, bamba ixesha kunye nobushushu bokuqhotsa.

7. Akukho nkcazo ecacileyo yobungakanani befomula yamanzi obhedu. Okokuqala faka izinto zobhedu kwi-smelting crucible, kwaye imali efakwe kuyo ixhomekeke kubunzima bokuphosa. Kwinkqubo yokunyibilika kobhedu, ngokombala welangatye (ubushushu bufikelela malunga ne-1300 ℃) kunye nenqanaba lokunyibilika kwamanzi obhedu, ngokuthe ngcembe ngokwamava (awanakulinganiswa), umlinganiselo we-zinc, i-tin, isinyithi. , ilothe kunye nezinye izinyithi zongezwa ukufezekisa umphumo wobunzima bomsebenzi.

1. Beka iqokobhe elibhakiweyo kwisanti kwaye uyingcwabe ukuya kwisiqingatha sokuphakama, kuba isanti ingakwazi ukulungisa i-shell shell, ukuze umahluko okhawulezayo wobushushu phakathi kweqokobhe kunye nangaphandle unokuphetshwa ngexesha lenkqubo yokuphosa, kwaye ine- isiphumo esihle sokufakelwa kwe-thermal. Ukuphosa kufuneka kugqitywe ngexesha elinye kwaye akunako ukumiswa phakathi okanye ukuzaliswa kwakhona. Ukuze kuthintelwe ukuhlukana kwamacandelo okubopha, kwanamanzi afanayo obhedu aya kuba nefuthe ngenxa yeqondo lokudibanisa elifakwe ngexesha lokuphosa. Enye kukuba ii-castings zibekwe ngokulula kwaye aziqini; enye kukuba iindawo ezicolekileyo zipholiswa kuqala, nto leyo echaphazela ubumanzi bokuphosa kwaye yenze i-engile yokuphosa efileyo; eyesithathu kukuqhekeka kwegobolondo lokungunda okubangelwa ngumahluko wobushushu.
