Nzira yekugadzirisa sei jekiseni pressure?

Mukugadzirisa kwemuchina wedu, tinowanzo shandisa multi-stage jekiseni.Yekutanga nhanho jekiseni rekudzora gedhi, yechipiri nhanho jekiseni rinodzora muviri mukuru, uye yechitatu nhanho jekiseni inozadza 95% yechigadzirwa, uye wobva watanga kuchengetedza kudzvanywa kuburitsa chigadzirwa chakazara.Pakati pavo, iyo jekiseni yekumhanyisa inodzora kunyungudika kuzadza chiyero, iyo jekiseni yekumanikidza ndiyo vimbiso yehuwandu hwekuzadza, nzvimbo yejekiseni inodzora kunyungudika kuyerera chinzvimbo, uye kumanikidza kuchengetedza kudzvanywa kunoshandiswa kugadzirisa huremu hwechigadzirwa, saizi, deformation, uye shrinkage.

>> Kwekutanga kutsunga kwekumanikidza jekiseni panguva yekutanga chigadzirwa uye kutumirwa:

Patakatanga muchina wekugadzirisa parameter, kudzvanywa kwejekiseni kwaizokwira kupfuura kukosha chaiko.

Nekuti jekiseni pressure yakanyanya kuderera, iyojekiseni mold(tembiricha) inotonhora zvakanyanya, uye kusviba kwemafuta pamusoro pegomba rekuumbwa kuchakonzera kupokana kukuru.Zvakaoma kuisa jekiseni kunyunguduka mukati mold cavity, uye haigoni kuumbwa nekuda kwekusakwana kudzvinyirira (kunamatira kuumbwa kwepamberi, kuvhara gedhi);Kana kudzvanywa kwejekiseni kwakanyanyisa, chigadzirwa chichava nekushushikana kukuru kwemukati, izvo zviri nyore kukonzera burrs uye kupfupisa hupenyu hwebasa re mold.Izvo zvinogona zvakare kutungamira kune plugging chinzvimbo chechigadzirwa, kuomerwa mukudhirowa, kukwenya pamusoro pechigadzirwa, uye kunyangwe mold ichawedzerwa mune dzakakomba kesi.Naizvozvo, kudzvanywa kwejekiseni kunofanirwa kuiswa zvinoenderana neanotevera mapoinzi panguva yekutanga uye yekumisikidza.

1. Chigadzirwa chimiro uye chimiro.

2. Kukura kwechigadzirwa (kunyunguduka kuyerera kureba).

3. Product ukobvu.

4. Zvinhu zvakashandiswa.

5. Mhando yegedhi rekuumbwa.

6. Screw tembiricha yemuchina wekuumba jekiseni.

7. Mold tembiricha (kusanganisira mold preheating tembiricha).

>> Kukanganisa kwakajairika kunokonzerwa nekumanikidza jekiseni mukugadzira

Iyo jekiseni pressure inonyanya kushandiswa kuzadza uye kudyisa iyo yakanyunguduka mugomba rekuumbwa.

Mukuzadza jekiseni kuumba, iyo jekiseni pressure iripo kuti ikunde kuramba kuzadza.Kana iyo yakanyungudika yaiswa jekiseni, inoda kukurira kupokana kubva mumhanyi wegedhi remhanyi mhango kuti ibudise chigadzirwa.Kana jekiseni rinomanikidza rinopfuura kuramba kuyerera, kunyunguduka kunoyerera.Haina kurongeka sekumhanya kwejekiseni uye chinzvimbo chejekiseni.Kazhinji, isu tinogadzirisa chigadzirwa nekumhanya sereferensi.Kuwedzera kwekumanikidzwa kwejekiseni kunogona kuchengetedza tembiricha yakakwira yekunyungudika uye kuderedza kurasikirwa kwekupokana kwechiteshi, Chikamu chemukati chechigadzirwa chakasimba uye chakakora.

>> Gadzirisa maitiro paramita mushure mekutumirwa kwechigadzirwa

Izvo zvinhu zvinokanganisa zvakananga kudzvanywa kwejekiseni: iyo inoyerera sitiroko yemhinduro, viscosity yezvinhu uye kudziya kwe mold.

Munzvimbo yakanaka, ndiyo yakanyanya sainzi kuti jekiseni kudzvanywa kwakaenzana nekudzvanywa kwegomba re mold, asi iyo chaiyo yekumanikidza ye mold cavity haigone kuverengerwa.Kunyanya kuoma kuzadza mold ndiko, ndiko kukura kwekumanikidza kwejekiseni, uye kureba kwekunyungudika kuyerera kuri kure.Iyo jekiseni pressure inoderera nekuwedzera kuzadza kuramba.Naizvozvo, jekiseni remultistage rinounzwa.Iyo jekiseni yekumanikidza yekumberi kunyunguduka yakaderera, iyo jekiseni yekumanikidza yepakati melt yakakwira, uye kudzvanywa kwejekiseni kwechikamu chekupedzisira kwakadzikira.Iyo yekukurumidza chinzvimbo inokurumidza uye inononoka chinzvimbo inononoka, uye maitiro maparamita anofanirwa kuvandudzwa mushure mekugadzirwa kwakagadzikana.

>> Chengetedzo yesarudzo yekumanikidza jekiseni:

1. Panguva yekugadzirisa parameter, kana kutonhora kwe mold kana kutonhora kwekuchengetedza kunoderera, zvakakosha kuisa jekiseni yakakura.

2. Kune zvinhu zvine fluidity yakanaka, yakaderera jekiseni kumanikidza kunofanira kushandiswa;Kune magirazi uye yakakwirira viscosity zvinhu, zviri nani kushandisa yakakura jekiseni kumanikidza.

3. Iyo yakaonda chigadzirwa chacho, iyo yakareba iyo nzira iri, uye iyo yakanyanya kuoma chimiro chacho, iyo huru yejekiseni inoshandiswa inoshandiswa, iyo inobatsira pakuzadza nekuumba.

4. Chiyero chezvimedu chechigadzirwa chakabatana zvakananga kana jekiseni rinomanikidzwa rakagadzirirwa zvakakodzera.Mhedzisiro yekugadzikana ndeyekuti michina yekuumba haina kusimba uye haina zvikanganiso zvakavanzwa.
