1. Ukujiya kodonga lomkhiqizo
(1) Zonke izinhlobo zamapulasitiki anohlu oluthile lokujiya kodonga, ngokuvamile luyi-0.5 kuya ku-4mm. Uma ugqinsi lwezindonga ludlula u-4mm, luzokwenza ukuthi isikhathi sokupholisa sibe side kakhulu futhi kubangele ukuncipha nezinye izinkinga. Cabangela ukushintsha ukwakheka komkhiqizo.
(2) Ukujiya kodonga okungalingani kuzobangela ukushwabana kwendawo.
(3) Ukuqina kodonga okungalingani kuzodala izimbotshana kanye nemigqa yokushisela.
2. Isiqondiso sokuvula isikhunta kanye nomugqa wokuhlukanisa
Ekuqaleni komklamo womkhiqizo ngamunye womjovo, indawo yokuvula isikhunta kanye nomugqa wokuhlukanisa kufanele kunqunywe kuqala ukuze kuqinisekiswe ukuthi indlela yesilayidi esidonsayo iyancipha futhi nomthelela womugqa wokuhlukanisa ekubukeni uyaqedwa.
(1) Ngemuva kokunqunywa kwesiqondiso sokuvula isikhunta, izimbambo eziqinisayo, amabhande, ama-protrusions nezinye izakhiwo zomkhiqizo zenzelwe ukuhambisana nesiqondiso sokuvula isikhunta ngangokunokwenzeka, ukuze kugwenywe ukudonsa okuyisisekelo nokunciphisa imigqa ye-seam futhi andise impilo yesikhunta.
(2) Ngemva kokunqunywa kwesiqondiso sokuvula isikhunta, umugqa wokuhlukanisa ofanelekile ungakhethwa ukuze ugweme i-undercut endaweni yokuvula isikhunta, ukuze kuthuthukiswe ukubukeka nokusebenza.
3. Ukwehlisa umthambeka
(1) Ukwehlela okufanelekile kungagwema ukuguquguquka komkhiqizo (ukudonsa). I-slope ye-demoulding ebusweni obubushelelezi kufanele ibe mkhulu noma ilingane nama-degree angu-0.5, ingaphezulu lesikhumba esihle (indawo yesihlabathi) kufanele ibe nkulu kune-1 degree, futhi ubuso besikhumba esimahhadla kufanele bube bukhulu kunama-degree angu-1.5.
(2) Umthambeka ofanele wokudilika ungagwema umonakalo ongaphezulu komkhiqizo, njengokumhlophe okuphezulu, ukuwohloka okuphezulu, nokugqabuka phezulu.
(3) Lapho uklama umkhiqizo onesakhiwo somgodi ojulile, umthambeka wendawo yangaphandle kufanele ube mkhulu kunomthambeka wendawo yangaphakathi ngangokunokwenzeka ukuze kuqinisekiswe ukuthi umgogodla wesikhunta awuchezuki ngesikhathi sokubunjwa komjovo, thola umkhiqizo ofanayo. ukujiya kodonga, futhi uqinisekise amandla ezinto ezibonakalayo okuvulwa komkhiqizo.
4. Ukuqinisa izimbambo
(1) Ukusetshenziswa okunengqondo kwezimbambo eziqinisayo kungakhuphula ukuqina komkhiqizo futhi kunciphise ukuwohloka.
(2) Ubukhulu be-stiffener kufanele bube ≤ (0.5~0.7) T ubukhulu bodonga lomkhiqizo, ngaphandle kwalokho ubuso buzoncipha.
(3) Umthambeka ohlangothi olulodwa lombambo oluqinisayo (i-Shanghai Mold Design Training School) kufanele ube mkhulu kuno-1.5° ukuze ugweme ukulimala okuphezulu.
