Umngundo udla ngokuba nenxalenye yecango kuphela kwaye akukho punch.Umphezulu wokungunda awufuni kuqina.Uxinzelelo lokubetha oluthwalwa ngumgodi luncinci kakhulu kunolo lwenaliti yokubumba, ngokubanzi i-0.2 ~ 1.0MPG, kwaye ixabiso liphantsi.
Vuthela umzobo wesakhiwo sokungunda
Izinto zokungunda
Ngokubanzi, i-alloy ye-aluminiyam isetyenziselwa ukuvelisa, kunye ne-beryllium yobhedu okanye i-alloy base base-copper nayo isetyenziselwa izinto zerabha ezonakalisayo ezifana ne-PVC kunye ne-POM.Kwimibumbo eneemfuno eziphakamileyo zobomi benkonzo, ezifana neeplastiki zokubumba ubunjineli be-ABS, i-PC, i-POM, i-PS, i-PMMA, njl., isinyithi esingenasici sifunekayo ukuba sisetyenziswe ukwenza iimbumba.

Amanqaku aphambili oyilo lokungunda
Umphezulu wokwahlula
Ngokuqhelekileyo, kufuneka ibekwe kwi-symmetry plane ukunciphisa umlinganiselo ovuthuzayo wokwandisa.Ngokomzekelo, kwiimveliso ze-elliptical, indawo yokuhlukana ikwi-axis ende, kunye neemveliso ezinkulu, zidlula kumgca ophakathi.
Umphezulu we-Cavity
Izinto ze-PE kufuneka zibe rhabaxa kancinci, kwaye umphezulu wesanti ecolekileyo ulungele ukukhupha;Ukubunjwa kokuvuthela kwezinye iiplastiki (ezifana ne-ABS, i-PS, i-POM, i-PMMA, i-NYLON, njl. njl.), umngxuma wokungunda ngokubanzi awunakuqhunyiswa yisanti, kwaye i-exhaust slot inokwenziwa kwindawo eyahlulayo yomgodi wokungunda, okanye umbhobho. umngxuma unokwenziwa kumgodi wokungunda, kunye nobubanzi bomngxuma wokukhupha kumgodi wokungunda ngokubanzi φ 0.1~ φ 0.3, ubude be-0.5 ~ 1.5mm.
Ubungakanani beCavity
Isantya sokucutheka kweeplastiki kufuneka siqwalaselwe kuyilo lobungakanani bomgodi.Ukufumana iinkcukacha, nceda ubhekisele kumazinga aqhelekileyo okunciphisa iplastiki.
Ukusika umgca kunye nomsila we-groove
Ngokubanzi, ukuvuthela iiplastiki zobunjineli kunye neeplastiki ezinzima, umgca wokusika kufuneka wenziwe ngezinto ezinokumelana nokunxiba kakuhle, njenge-beryllium yobhedu, insimbi engenasici, njl. .
Umgca wokusika kufuneka ukhethwe ngobukhulu obufanelekileyo.Ukuba incinci kakhulu, iya kunciphisa amandla okudibanisa.Ukuba inkulu kakhulu, ayinakunqunyulwa kwaye i-clamping edge kwindawo yokwahlula inkulu.Nangona kunjalo, i-groove yomsila ivuliwe ngaphantsi kwe-cut cut, kwaye i-groove yomsila yenzelwe ukuba ibe yi-angle edibeneyo.Xa usika, umlinganiselo omncinci wokuncibilika unokunyanzeliswa kwi-joint, ngaloo ndlela uphucula amandla okubambisana.
Isitofu sokuvuthela ngundo
Uyilo lwahlukile kwi-extrusion blow molding.Umahluko omkhulu kukuba i-injection blow mold ayifuni ukusika i-edge kunye ne-tailing groove.Uyilo olungenanto lwenxalenye yokuvuthela kwenaliti lubaluleke kakhulu, oluchaphazela ngokuthe ngqo umgangatho wemveliso egqityiweyo.
Isitofu sokungunda - imigaqo yokuyila i-parison
1. Ubude, ububanzi kunye nobude ≤ 10/1
2. Ukuvuthela umlinganiselo wokwandisa 3/1 ~ 4/1 (umlinganiselo wobungakanani bemveliso ukuya kwisayizi ye-parison)
3. Ubukhulu bodonga 2 ~ 5.0mm
4. Ngokwemilo yemveliso, ubukhulu bodonga bukhulu apho umlinganiselo wokuvuthela bukhulu, kwaye uncinci apho umlinganiselo wokuvuthela uncinci.
5. Kwimigqomo e-elliptical ene-ellipse ratio enkulu kune-2/1, intonga engundoqo iya kuyilwa njenge-ellipse.Kwiimveliso ze-elliptical kunye ne-ellipse ratio engaphantsi kwe-2/1, intonga ejikelezayo ejikelezayo inokwenza isitya se-ellipse.
Uyilo lwentonga yokuvuthela
Ulwakhiwo lwentonga yokuvuthela komoya lumiselwa ngokwesakhiwo sokungunda kunye neemfuno zemveliso.Ngokubanzi, uluhlu olukhethiweyo lomngxuma wentonga yokungenisa umoya lu:
L<1: aperture φ one point five
4> L>1: indawo yokuvula φ inqaku lesithandathu
200>L>4: indawo yokuvula φ 12.5 (L: umthamo, iyunithi: ilitha)
Uxinzelelo lomoya lokubumba okuqhelekileyo kweplastiki
