1. Rubber jekiseni molding: Rubber jekiseni molding inzira yekugadzira iyo zvinhu zverabha zvinoiswa zvakananga mumuenzaniso kubva mubhodhoro kuitira vulcanization. Zvakanakira zvekuumbwa kwejekiseni rerabha ndezvi: kunyangwe kuri kushanda kwepakati, kutenderera kupfupi, kugona kwekugadzira kwakakwira, nzira yekugadzirira isina chinhu yakabviswa, kuwanda kwevashandi kudiki, uye mhando yechigadzirwa yakanaka.
2. Plastic jekiseni molding: Plastic jekiseni molding inzira yezvigadzirwa zvepurasitiki. Purasitiki yakanyungudutswa inopinzwa muforoma yezvigadzirwa zvepurasitiki nekumanikidza, uye zvikamu zvepurasitiki zvinodikanwa zvinowanikwa nekutonhodza nekuumba. Kune mechanical jekiseni molding michina yakatsaurirwa kuita jekiseni molding. Ipurasitiki inonyanya kushandiswa nhasi ndeye polystyrene.
3. Kuumba nekuumba jekiseni: Chimiro chinoguma chinowanzova chigadzirwa chekupedzisira, uye hapana kumwe kugadzirisa kunodiwa kusati kwaiswa kana kushandiswa sechigadzirwa chekupedzisira. Ruzhinji ruzivo, senge maboss, mbabvu, uye shinda, zvinogona kuumbwa mune imwechete jekiseni rekuumba oparesheni.
Injection molding ishangu yakagadzirwa nemushini. Mushure mekunge nzvimbo yepamusoro yakasungirirwa paaluminium yekupedzisira, inowanzoiswa zvakananga muPVC, TPR uye zvimwe zvinhu nemuchina unotenderera kuti uite iyo chete panguva imwe chete. Nhasi, kune zvakare PU (kemikari zita polyurethane) jekiseni rekugadzira (muchina uye mold ine General jekiseni molding yakasiyana).
Zvakanakira: Nekuti inogadzirwa nemuchina, iyo inobuda yakakura, saka mutengo wakaderera.
Zvakaipa: Kana pane zvitaera zvakawanda, zvinonyanya kunetsa kuchinja mold, shangu dzakaoma kuumba, uye hapana shangu dzinotonhora-inonamira dzine hunyanzvi hwekuita, saka inowanzoenderana neodha ine imwe chete maitiro.
Chinangwa, kushanda uye mhedzisiro yekushisa, kumanikidza, kumhanya uye kutonhora kutonga
● Kugadziriswa kwejekiseni molding machine settings kunokanganisa sei maitiro uye unhu
●Optimize screw control settings
● Multi-stage kuzadza uye multi-stage kudzvinyirira-kubata kutonga; pesvedzero yecrystallization, amorphous uye molecular/fiber orientation pamaitiro uye mhando
● Pesvedzero yekushushikana kwemukati, chiyero chekutonhora uye shrinkage yepurasitiki pamhando yezvikamu zvepurasitiki
Rheology yemapurasitiki: mafambiro epurasitiki, kutenderera uye kuchinja viscosity, shear uye mamorekuru/fiber orientation.
● Hukama pakati pekudira sisitimu, kutonhora system, mold chimiro uye jekiseni molding process
Shrinkage cavity, shrinkage, unsaturated mold, burr, weld line, sirivheri wire, spray mark, kupisa, warpage deformation, kuputika / kutsemuka, dimension kunze kwekushivirira uye zvimwe zvinowanzoitwa jekiseni kuumba tsanangudzo dambudziko, chikonzero chekuongorora, uye mukugadzira mold, kuumba Solutions. yekutonga kwemaitiro, kugadzirwa kwechigadzirwa uye zvinhu zvepurasitiki.
● Cause wongororo uye nhanho dzekushaikwa kweglue uye unsaturated mold yakatenderedza jekiseni molding parts
●Kuongorora kwechikonzero uye mhinduro
●Kukonzeresa kuongororwa uye matanho ekuderera kwepasi uye shrinkage cavity (vacuum bubble) yezvikamu zvakaumbwa jekiseni.
● Ongororo yechikonzero nemhinduro dzesirivheri mitsetse (ruva rezvinhu, kupfacha kwemvura), kupisa, uye gasi streaks.
●Kukonzeresa kuongororwa uye kuyerwa kwekuyerera kwemvura uye kuyerera mamaki (kuyerera mamaki) pamusoro pezvikamu zvakaumbwa jekiseni.
●Kukonzeresa kuongororwa uye kuyerwa kwemavara emvura (weld lines) uye mavanga ekupfapfaidza (serpentine mamaki) pamusoro pezvikamu zvakaumbwa jekiseni.
●Kukonzeresa kuongororwa uye matanho ekutsemuka kwepasi (kutsemuka) uye kuchena kwepamusoro (kuputika kwepamusoro) kwezvikamu zvakaumbwa jekiseni.
● Kuongorora kwechikonzero uye matanho ekusiyana kwemavara, kupenya kusina kunaka, kusanganiswa kwemavara, mitsetse mitema uye mavara matema pamusoro pezvikamu zvakaumbwa zvejekiseni.
●Kukonzeresa kuongororwa uye matanho ekugadzirisa deformation uye kushushikana kwemukati kuputika kwemajekiseni akaumbwa zvikamu
● Chikonzero chekuongorora uye matanho ekutsauka kwedimensional yezvikamu zvakaumbwa zvejekiseni
●Kukonzeresa kuongororwa uye nhanho dzemajekiseni ekuumba zvikamu zvinonamira kune mold, kukweva (kunetsa) uye kudhonza chena.
●Kukonzeresa kuongororwa uye nhanho dzekusakwana pachena uye kusakwana simba (brittle fracture) yezvikamu zvakaumbwa jekiseni.
●Kukonzeresa kuongororwa uye nhanho dzenzvimbo inotonhora uye peeling (layer) pamusoro pemajekiseni akaumbwa zvikamu.
● Cause wongororo uye nhanho dzekupinzwa kwesimbi dzisina kunaka dzezvikamu zvakaumbwa zvejekiseni
●Kukonzeresa uye kugadzirisa matanho ekudonha kwemhino (inomhanya mhino), glue kubuda, kudhirowa kwewaya yemuromo, kuvharika kwemhino, uye kutadza kuvhura mold.
● Kushandisa CAE mold flow analysis tekinoroji kukurumidza uye zvinobudirira kugadzirisa matambudziko epa-saiti mukuumba jekiseni
