jekiseni molding muchina chimiro:shanda, zvakanakira (zvichienzaniswa nemamwe)

Jekiseni Molding:
Zvikamu zvikuru zve Jekiseni Molding Machine:
Zvikamu zvikuru zveInjection molding muchina zvinhu hopper, barrel, gondohwe rejekiseni/kutenderedza sikuruu rudzi plunger, kudziyisa mudziyo (heater), patani inofambika, ejectors, uye mold mukati memhango yeforoma.

Kazhinji majekiseni ekuumba majekiseni anoshanda nenzira yakachinjika. Jekiseni molding muchina une dhiramu (cylindrical pipe). Hopper inowanikwa kune imwe mugumo wedhiramu. Gondohwe re hydraulic kana screw inotenderera inomhanyisa mota yemagetsi inoshandiswa kupa simba inowanikwa mukati medhiramu.. Chinhu chinopisa (heater) inosungirirwa padhiramu rinoshandiswa kunyungudutsa zvinhu zvekuumba zvinodzika kubva muhopi..

Kune rumwe rutivi rwebhari pane mold cavity yakabatanidzwa. Mould inowanikwa mukati memugodhi uye pateni inofambiswa inoshandiswa mukugadzira kwese. Mould inowanzogadzirwa nemhangura, aluminium uye simbi yemidziyo. Hupenyu hwekutenderera kwemhando dzakasiyana dzezvinhu zvakasiyana. Izvi zvinogona kusarudzwa maererano nezvinodiwa.

Kushanda:
Kushanda kwejekiseni molding yakafanana neye extrusion uye inoshanda senge jekiseni sekureva kunoita zita. Molding material/ raw material inodira muhopi nemudziyo wekudyisa. Mushure meiyo yekuumba zvinhu inodzika pasi pechiito chegiravhiti muhumburumbira (barrel) sezvinoratidzwa mumufananidzo. A circumferential heater iyo iri padhiramu inoshandiswa kunyungudutsa zvinhu. Kana hupfu hwehupfu hwezvinhu zvekuumba hwaenda mambakwedza huchipinda mudhiramu kubva muhopi hunotanga kunyunguduka uye gondohwe rehydraulic kana screw inotenderedza inosundira zvinhu kumberi muforoma nekuisa imwe dzvinyiriro.. Zvinhu zvepurasitiki zvakanyungudutswa zvinoiswa muforoma yakavharika yakasungirirwa kune rimwe divi redhiramu; mune iyi kupatsanurwa mold inoshandiswa. Molding material inoenda kumberi zvichienda mberi nekona inotenderera. Kudzvinyirira kunoshanda neiyo hydraulic system. Jekiseni pressure kazhinji 100-150 MPa. Mushure mejekiseni; pressure inoshandiswa kwenguva yakati kana kuvharwa panzvimbo imwe neimwe simba.

Mushure mokunge nzira yose yaitwa zvikamu yakagadzirwa yakatonhodzwa zvakakwana. Ipapo mold yakavhurika uye mamwe ejector anoshandiswa kubviswa kwakakodzera kwechikamu pasina kukuvara. Mushure mekubvisa chikamu mold yakavharwa zvakare. Iyi nzira inokurumidza uye inodzokororwa otomatiki. Pano zvakaoma chimiro zvikamu zvinogona kugadzirwa nyore nyore. Kugadzira kugona kwejekiseni molding ndiko 12-16 zviuru zvikamu kutenderera.

kubatsirwa:
Kubatsira kukuru kweiyi nzira ndeyekuti zvikamu zvine maumbirwo akaoma ane diki madziro ukobvu (5-15 mm) inogona kuumbwa nyore nyore uye kubviswa kubva mufodya pasina kukuvara.
Zvikamu zvakagadzirwa nejekiseni molding zvine zvakanaka dimensional tolerances.
Kubatsira kukuru kweiyi tekinoroji ndeyekuenzaniswa nedzimwe nzira, nzira iyi inobudisa tsvina yakawanda.
Zvikamu zvinogadzirwa kuburikidza nemajekiseni ekuumba maitiro anokwikwidzana nezvikamu zvinogadzirwa kuburikidza nekudyara kwekudyara uye yakaoma makina zvikamu.
Kuenzaniswa nemamwe matekinoroji, nzira iyi ine kugadzirwa kwepamusoro.
