I-mold yeplastiki iqulunqwe ikakhulu ngamacandelo amathathu: inkqubo yokuthulula, iindawo ezibunjiweyo kunye nezakhiwo. Inkqubo yokugalela kunye neendawo ezibunjiweyo ngamalungu adibanisa ngokuthe ngqo neplastiki kunye nokutshintsha kunye neemveliso zebhokisi zeplastiki. Zezona zintsonkothileyo kwaye zitshintsha kakhulu kwiimbumba zeplastiki. Bafuna ukugqitywa kokulungiswa. Kwaye eyona nxalenye ichanekileyo.
Inkqubo yokugalela iplastiki yokungunda ibhekisa kwindawo yembaleki phambi kokuba iplastiki ingene kumngxuma isuka kumbhobho, kubandakanywa imbaleki ephambili, i-slug ebandayo, imbaleki kunye nesango, njl njl. ukungunda okushukumayo, ukungunda okungaguqukiyo kunye nemingxuma, iicores, izinto zokubumba kunye neendawo zokuphuma.
1. Eyona nto iphambili
Yindlela yokubumba edibanisa i-nozzle yomshini wokutofa kumgijimi okanye kwi-cavity. Umphezulu wembaleki ephambili i-concave ukwenzela ukudibanisa nomlomo.
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 kwi-5 ° ukuququzelela ukudilizwa kwembaleki.
2.umngxuma wezinto ezibandayo
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.
Ububanzi bombhobho wezinto ezibandayo malunga ne-8-l0mm, kwaye ubunzulu yi-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.
3. imbaleki
Ingumjelo odibanisa imbaleki ephambili kunye nomngxuma 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 kwendlela yokuhamba kwecandelo lomnqamlezo wesetyhula kuncinci. Nangona kunjalo, ngenxa yokuba indawo ethile yomqhubi we-cylindrical incinci, ayithandeki ukupholisa umgijimi ongafunekiyo, kwaye umgijimi kufuneka avulwe kwii-halves ezimbini zokubumba, ezisebenzayo kwaye kulula ukulungelelanisa.
