Isikhunta ngokuvamile sinengxenye yomgodi kuphela futhi akukho punch.Isikhunta ngokuvamile asidingi ukuqina.Ingcindezi yokushaya ethwelwe yisikhala incane kakhulu kunaleyo yokubumba umjovo, ngokuvamile ingu-0.2~1.0MPG, futhi izindleko ziphansi.
Vuthela umdwebo wesakhiwo sesikhunta
Isikhunta impahla
Ngokuvamile, ingxubevange ye-aluminium isetshenziselwa ukukhiqiza, kanti i-beryllium yethusi noma i-copper base alloy nayo isetshenziselwa izinto zenjoloba ezonakalisayo njenge-PVC ne-POM.Ezikhunjini ezinezidingo zempilo ephakeme yesevisi, ezifana namapulasitiki okubumba ubunjiniyela be-blow ABS, i-PC, i-POM, i-PS, i-PMMA, njll., insimbi engagqwali iyadingeka ukuze isetshenziselwe ukwenza isikhunta.
isikhunta
Amaphuzu abalulekile wokuklama isikhunta
Indawo yokuhlukanisa
Ngokuvamile, kufanele ibekwe endizeni ye-symmetry ukuze kuncishiswe isilinganiso sokunweba esivunguzayo.Isibonelo, ngemikhiqizo eyi-elliptical, indawo ehlukanisayo iku-eksisi ende, futhi ngemikhiqizo emikhulu, idlula emgqeni ophakathi.
Indawo yomgodi
Izinto ze-PE kufanele zibe lukhuni kancane, futhi ubuso besihlabathi esihle buvumela ukuphuma;Ukuze kuqhutshwe amanye amapulasitiki (afana ne-ABS, PS, POM, PMMA, NYLON, njll.), isikhunta ngokuvamile asikwazi ukuqhunyiswa ngesihlabathi, futhi i-exhaust slot ingenziwa endaweni yokuhlukanisa isikhunta, noma i-exhaust. umgodi ungenziwa emgodini wesikhunta, kanye nobubanzi bomgodi wokukhipha emgodini ojwayelekile wesikhunta φ 0.1 ~ φ 0.3, ubude 0.5 ~ 1.5mm.
Usayizi we-cavity
Izinga lokuncipha kwamapulasitiki kufanele licatshangelwe ekwakhiweni kosayizi womgodi.Ukuze uthole imininingwane, sicela ubhekisele kumazinga avamile wokushwabana kwepulasitiki.
I-Cutting edge kanye ne-tailing groove
Ngokuvamile, amapulasitiki okubumba ubunjiniyela namapulasitiki aqinile, unqenqema lokusika kufanele lwenziwe ngezinto ezinokumelana nokugqokwa okuhle, njengethusi le-beryllium, insimbi engagqwali, njll. Nge-LDPE, EVA neminye imikhiqizo yepulasitiki ethambile, ingxubevange ye-aluminium ejwayelekile ingasetshenziswa. .
Umkhawulo wokusika kufanele ukhethwe ngosayizi onengqondo.Uma incane kakhulu, izonciphisa amandla elunga.Uma inkulu kakhulu, ayikwazi ukunqunywa futhi unqenqema lokubopha endaweni yokuhlukanisa inkulu.Kodwa-ke, i-groove enomsila ivuliwe ngaphansi komkhawulo wokusika, futhi i-groove yomsila iklanyelwe ukuba ibe i-engeli ehlanganisiwe.Lapho usika, inani elincane lokuncibilika lingakhanywa ekuhlanganyeleni, ngaleyo ndlela lithuthukise amandla okuhlangana.
Isikhunta sokushaya umjovo
Umklamo uhlukile ku-extrusion blow molding.Umehluko omkhulu ukuthi isikhunta sokushaya umjovo asidingi ukusika unqenqema kanye ne-tailing groove.Umklamo ongenalutho wengxenye yokushaywa komjovo kubaluleke kakhulu, okuthinta ngokuqondile ikhwalithi yomkhiqizo oqediwe.
Isikhunta sokujova - izimiso zokuklama i-parison
1. Ubude, ububanzi nobude ≤ 10/1
2. Isilinganiso sokunweba esivunguzayo 3/1~4/1 (isilinganiso sosayizi womkhiqizo nosayizi wesonto)
3. Ukujiya kodonga 2~5.0mm
4. Ngokwesimo somkhiqizo, ubukhulu bodonga bukhulu lapho isilinganiso sokushaywa sikhulu, futhi buncane lapho isilinganiso sokushaywa sincane.
5. Eziqukathi eziyiziyingi ezinezinga le-ellipse elikhulu kuno-2/1, i-core rod izoklanywa njenge-ellipse.Emikhiqizweni eyi-elliptical enesilinganiso se-ellipse esingaphansi kuka-2/1, induku ewumgogodla oyindilinga ingakha isitsha se-ellipse.
Umklamo wenduku yokuqhuma
Isakhiwo senduku evuthela umoya sinqunywa ngokuya ngesakhiwo sesikhunta kanye nezidingo zomkhiqizo.Ngokuvamile, uhla olukhethiwe lobubanzi bembobo yenduku yokungenisa umoya yilo:
L<1: aperture φ one point five
4> L>1: ukuvuleka φ amaphuzu ayisithupha amahlanu
200>L>4: indawo φ 12.5 (L: ivolumu, iyunithi: ilitha)
Ukucindezela komoya kokubunjwa kwepulastiki evamile
