Hollow blow molding ndiyo extrusion kana jekiseni molding inowanikwa nehafu-yakanyunguduka epurasitiki billet kune akasiyana akaumbwa abrasive, akavharika abrasive, mubillet zvinoenderana nemhepo yekumanikidza kuvhuvhuta, kuti inosangana nemadziro eabrasive, mushure mekutonhora. mold uye hollow crafts.Inogona kushandiswa kugadzira mafuta anodyika, zvinwiwa, zvinwiwa, mwaka, mukaka uye zvimwe zvinhu zvekurongedza chikafu nemabhodhoro epurasitiki, akasiyana annular, sikweya, akaumbwa uye ane madhiri egonhi, makeni uye mamwe maburi emaoko.
Hollow blow molding ndiko deformation yepurasitiki yepurasitiki isina chinhu yakaiswa muchigayo chekukuya, kudzvanywa kwemhepo mukati isina chinhu, kuiputira kumusoro, ita kuti ive pedyo nemadziro emadziro, mushure mekutonhodza kuti uwane imwe chimiro chesimbi yepurasitiki kugadzirwa uye kugadzirisa. .Maererano nekuumba nzira haina kufanana, inogona kukamurwa kuva nzira ina.
1, extrusion blow molding
1 - Extrusion muchina musoro 2 - kuputira kuumba kufa 3 - tubular billet 4 - air compression boiler blow chubhu 5 - zvikamu zvepurasitiki
Yekutanga extruder extruded tubular billet;Bvisa chikamu chekupedzisa kukungurutsa pombi woiisa muchigayo chekukuya kuchipisa, vhara mativi ekuruboshwe nekurudyi eimwe clamping type isina blank yeguyo rakashama;
Zvadaro kune concave kufa mumhepo compression, kuitira kuti billet kuvhuvhuta uye akabatanidzwa yomukati rusvingo kufa musimboti tafura;
Pakupedzisira, mushure mekuchengetedza kudzvinyirira, firiji uye kuumba, inogona kubvisa kudzvinyirira kwemhepo uye mold kubvisa zvikamu zvepurasitiki.
Extrusion blow molding mold dhizaini iri nyore, iyo purojekiti yekudyara ishoma, iko kushanda kuri nyore kwazvo, kwakakodzera akasiyana epurasitiki hollow blow molding.Extrusion blow molding defects hazvisi nyore kune symmetrical madziro ukobvu, zvikamu zvepurasitiki zvinoda kugadziriswa mushure mekubviswa kweburr.
2, jekiseni blow molding
1 — Injector nozzle 2 — Type yetsono isina chinhu 3 — hollow mold base (core) 4 — Magetsi heater 5 — blow mold 6 — maplastic parts
Yekutanga jekiseni mold mumushini wejekiseni kuita hollow spectral type isina chinhu;
Ipapo iyo core uye billet inotamirwa mukati mekuvhuvhuta mold mold, iyo core haina mhango uye madziro emukati ane microporous plate;
Zvadaro, mold yakavharwa uye yakamanikidzwa kubva papombi ye core shaft mumhepo, kuitira kuti iyo isina chinhu ichiputirwe uye inosungirirwa kumadziro emukati we concave mold pamusoro pechimbo chinoputika;
Pakupedzisira, mushure mekuchengetedza kudzvinyirira, firiji uye kuumba, inogona kubvisa kudzvinyirira kwemhepo uye mold kubvisa zvikamu zvepurasitiki.
Chakanakira jekiseni blow molding ndechekuti ukobvu hwemadziro ezvikamu zvepurasitiki zvakanyatsorongeka pasina kubhururuka kumucheto, pasina kugadzirwa uye kugadzirisa.Nekuda kweiyo tsono yemhando isina spectrum, saka hapana chakabatana pazasi pezvikamu zvepurasitiki, yakakwira yekumanikidza simba, kugadzirwa kwakanyanya uye kugona kwekugadzira, asi iyo purojekiti yekudyara muchina nemidziyo uye maturusi abrasive yakakura kwazvo, kunyanya kune batch. kugadzirwa kwezvikamu zvepurasitiki zvidiki uye zvepakati.
3, jekiseni kutambanudza kuvhuvhuta kuumba
1 - Injector nozzle 2 - jekiseni mold 3 - stretch mandrel (boiler blow tube) 4 - kuputira mold 5 - zvikamu zvepurasitiki
Jekiseni rinotambanudza kuvhuvhuta kuumba ndiyo nzira yekugadzira uye yekugadzirisa iyo jekiseni rekugadzira spectral blank rinopisa kune yakakodzera tembiricha pazasi pemhinduro poindi yozoiswa mumudziyo wekuputira.Iyo tsvimbo yekuwedzera inotanga kuitiswa radial kutambanudza uye yozopinda mumhepo compression blow molding.
Mushure mekutambanudza kuvhuvhuta kwakaumbwa zvikamu zvepurasitiki zvekujeka kwayo, kukanganisa kuramba kumanikidza simba, simba repamusoro, kuomarara kwekukotama uye hunhu hwekudzivirira hutsi hunowanzo kuvandudzwa.Jekiseni yakatambanudzwa inovhuvhuta inoumba inonyanya kujairika mutsara polyester mineral mvura mabhodhoro.Jekiseni yakatambanudzwa inovhuvhuta kuumba inogona kukamurwa kuita inopisa billet nzira uye inotonhora billet nzira mbiri dzekuumba nzira.
Yekutanga jekiseni kuumba hollow spectral blank;Fambisa billet kune kutambanudza uye kuvhuvhuta molding fixture kuita kutambanudza uye kuvhuvhuta kuumba;Mushure mekumanikidza kuchengetedza, firiji kunze kwe mold yakabvisa zvikamu zvepurasitiki.
Iri rudzi rwekuumba nzira inochengetedza kudzoreredzwa kweinotonhora billet uye inochengetedza simba.Pamusoro pezvo, iyo billet system uye kutambanudza kuvhuvhuta kunoitwa pamushini mumwechete uye midziyo, iyo inogara munzvimbo diki, yakanakira kuenderera mberi kwekusimudzira kwekugadzira nekugadzira, uye ine yakakwirira mwero weautomation tekinoroji.
Cold billet jekiseni rinotambanudza blow blow molding ndiko jekiseni reyakanaka billet tembiricha kune tembiricha yakakodzera uye wozoiisa mumhepo yekuvhuvhuta mold kuita kutambanudza kuumba kuumba.Paunenge uchisarudza inotonhora billet yekugadzira nzira, jekiseni rebillet uye kutambanudza kuvhuvhuta kuumbwa kwezvikamu zvepurasitiki kunoitwa pamakina akasiyana nemidziyo zvichiteerana.Pamberi pekutambanudza kuvhuvhuta, kuitira kutsiva kupisa kunoburitswa nefiriji yebillet, kupisa kwechipiri kunofanirwa kuitwa kuti ive nechokwadi chekutambanudza kuvhuvhuta kwebillet.
4 pepa repurasitiki rinoputika kuumba
Plastiki shizha rinofuridza kuumba jekiseni kuumba kana extrusion kuumba epurasitiki pepa kudziyisa, ita kuti ive yakapfava, mukati me concave mold, yakavharirwa pakati peplasitiki ndiro mumhepo yekumanikidza uye kugadzira buri repurasitiki zvikamu.
