Kwinkqubo yeumatshinikunye nemveliso yokubumba isitofu, yinkqubo edibeneyo, engenako ukwahlulwa.
Ekubunjweni kwesitofu, inkqubo yokungena ibhekisa kwindawo yembaleki phambi kokuba iplastiki ingene emngxunyeni isuka kumbhobho, kubandakanywa imbaleki ephambili, umngxuma wezinto ezibandayo, imbaleki kunye nesango, njl.njl.
Inkqubo yokugalela ikwabizwa ngokuba yinkqubo yembaleki.Iseti yeendlela zokutya ezikhokelela kwiplastiki enyibilikayo ukusuka kumbhobho womatshini wokutofa ukuya kumngxuma.Ngokuqhelekileyo iquka imbaleki ephambili, imbaleki, isango kunye nomgodi wezinto ezibandayo.Ihambelana ngokuthe ngqo nomgangatho wokubumba kunye nokusebenza kakuhle kwemveliso yeemveliso zeplastiki.
Indlela engundoqo yokutofa iMold:
Yindlela yokubumba edibanisa umbhobho we-injection yomshini wokubumba kwimbaleki okanye kwi-cavity.Umphezulu we-sprue u-concave ukuze udibanise nombhobho.Idayamitha yesixhobo sokungena sembaleki esiphambili kufuneka sibe sikhulu kancinane kunedayamitha yombhobho (0.8mm) ukunqanda ukuphuphuma kunye nokuthintela ezi zimbini ukuba zingavalwa ngenxa yonxibelelwano olungachanekanga.Ububanzi bokungena kuxhomekeke kubukhulu bemveliso, ngokubanzi 4-8mm.Ububanzi bombaleki oyintloko kufuneka kwandiswe ngaphakathi kwi-engile ye-3 ° ukuya ku-5 ° ukuququzelela ukudilizwa kwembaleki.
I-Slug ebandayo:
Ingumngxuma ekupheleni kwembaleki ephambili ukubambisa izinto ezibandayo ezenziwe phakathi kweenaliti ezimbini ekupheleni komlomo ukuthintela ukuvaleka komgijimi okanye isango.Emva kokuba izinto ezibandayo zixutywe kwi-cavity, uxinzelelo lwangaphakathi lunokwenzeka ukuba lwenzeke kwimveliso eyenziwe.Ubukhulu bomngxuma we-slug obandayo bumalunga ne-8-10mm kwaye ubunzulu buyi-6mm.Ukuze kuququzelelwe ukuchithwa, i-bottom isoloko ithwalwa yintonga yokudiliza.Umphezulu wentonga yokuqhawula kufuneka uyilwe kwi-zigzag hook shape okanye usethe kunye ne-groove edibeneyo, ukwenzela ukuba i-sprue ikhutshwe kakuhle ngexesha lokuchithwa.
Shunt:
Ingumjelo odibanisa umjelo oyintloko kunye nomgodi ngamnye kwi-multi-slot mold.Ukuze wenze i-melt igcwalise i-cavities ngesantya esifanayo, ukucwangciswa kwabagijimi kwi-mold kufuneka kube yi-symmetrical and equidistant.Ubume kunye nobukhulu becandelo elinqamlezayo lomgijimi linempembelelo ekuhambeni kweplastiki yokunyibilika, ukuchithwa kwemveliso kunye nobunzima bokuvelisa isikhunta.Ukuba ukuhamba kwexabiso elifanayo lezinto ezisetyenzisiweyo, ukuchasana kwejelo lokuhamba kunye ne-circular cross-section yincinci.Nangona kunjalo, ngenxa yokuba indawo ethile yomqhubi we-cylindrical incinci, ayifanelekanga ukupholisa umgijimi ongafunekiyo, kwaye umgijimi kufuneka avulwe kwii-halves ezimbini zokubumba, ezisebenza ngamandla kwaye kunzima ukulungelelanisa.Ngoko ke, i-trapezoidal okanye i-semicircular cross-section runners isoloko isetyenziswa, kwaye ivulwa kwisiqingatha se-mold ngentonga yokuqhawula.Umphezulu wembaleki kufuneka uphuculwe ukunciphisa ukuchasana nokuhamba kunye nokubonelela ngesantya sokuzalisa ngokukhawuleza.Ubungakanani bombaleki buxhomekeke kuhlobo lweplastiki, ubukhulu kunye nobukhulu bemveliso.
Ubuninzi be-thermoplastics, ububanzi becandelo lomnqamlezo lwabagijimi aludluli i-8mm, ezongezelelweyo-ezinkulu zinokufikelela kwi-10-12mm, kunye nezincinci ezincinci 2-3mm.Kwisiseko sokuhlangabezana neemfuno, indawo enqamlezileyo kufuneka incitshiswe ngokusemandleni ukunyusa i-debris yomgijimi kunye nokwandisa ixesha lokupholisa.
