sei kusarudza jekiseni kuumba muchina

Pane matemplate maviri pane jekiseni kuumba muchina, mumwe haasi kufamba, inonzi fixed template; imwe yacho inogona kufambiswa, inonzi kufamba template. Iyo mold inogadziriswa pane maviri matemplate nema screws uye kudzvanya mahwendefa zvakateerana. Kana chakuvhe chikavhurwa, iyo inofambiswa template yemuchina wekuumba jekiseni inofamba, nokudaro uchityaira mold kuvhura.

Mushure me mold inogadzirwa, zvakakosha kuita jekiseni molding, isa pamushini wekuumba jekiseni, uye kutanga kugadzira zvigadzirwa. Zvisinei, kune akawanda mamodheru emajekiseni ekuumba michina, uye imwe neimwe jekiseni yekuumba muchina ine yayo paramita. Iyo dhizaini mold inofanirwa kukwanisa kuzadzisa zvinodiwa zveiyo jekiseni molding muchina modhi inopihwa nemutengi, zvikasadaro hazvizokwanisi kubereka. To

Kune dzakawanda dhizaini parameters yemuchina wekuumba jekiseni. Izvi zvinotevera zvinotarisa pane akati wandei ma parameter ane chekuita ne mold. Ndinovimba kuti vaverengi vachateerera kune chaiyo dhizaini ye mold. To

1. Injection volume
Iro jekiseni vhoriyamu ndiyo yakanyanya kuwanda kukosha (kana kukosha kwevhoriyamu) kuti jekiseni rekugadzira muchina unogona kupfura panguva imwe panguva yekugadzira, uye inomiririra huwandu hwejekiseni remhando iyi yemuchina wekuumba jekiseni. Huwandu hwekunyunguduka hunoshandiswa mu mold yakagadzirwa ishoma pane jekiseni vhoriyamu yemuchina wekuumba jekiseni. Zvikasadaro, chigadzirwa hachigutsikane uye hachigone kubudiswa. To

2. Clamping force
Chii chakaitika kwaive kudzvanya kwemushini wekuumba jekiseni pane template apo mold yakavharwa. Simba rekusungirira rinodiwa kune chigadzirwa chakaumbwa panguva yekuumbwa kunofanirwa kunge kuri kushoma pane yakatemerwa clamping simba yemuchina wakasarudzwa wekuumba jekiseni.. Zvikasadaro, glue yakanyungudutswa inomhanya nyore kubva pane inoparadzana, zvichikonzera kupenya.

3. Sunga nzvimbo yetsvimbo
Kune mana anosunga tsvimbo mumakona akafa eiyo yakagadziriswa template uye inofambiswa template yemuchina wekuumba jekiseni.. Basa ravo ndere kuona kuti jekiseni rekuumba muchina rine simba rakakwana uye kusimba, uye panguva imwechete ine mutoro weiyo inotsvedza template. Zvisinei, inotarisa kudzikamisa zviyero zvese zve mold, nokuti mold inokwidziridzwa kubva pakati pechisungo chekuisa panguva yekuiswa. To

Zviyero zve mold hazvigoni kuva zvakakura kudarika chinhambwe pakati pezvisungo zvekusungira. Kana kureba kwechiumbwa kuchidarika chinhambwe pakati pezvisungo zvekusunga, tarisa kana mold yakasimudzwa mumusangano wetsvimbo nekutenderera. Kana iyo rotary hoisting haigone kuitwa, ipapo ukuru hwekuumbwa hunogona kuchinjwa chete. , Kana kutsiva muchina wekuumba jekiseni. To

4. Nozzle size check
Musoro wemhuno yemuchina wekuumba jekiseni unowanzo tenderera. Pakusarudza sprue sleeve, spherical radius ye sprue sleeve inofanirwa kuenderana ne spherical radius yemuromo. Kuti udzivise kunyungudika kwepamusoro-soro kunyunguduka kubva pamukaha wekubatana pakati pemhuno nesprue sleeve., denderedzwa remupendero weruoko rwesprue kazhinji unofanirwa kunge wakakura kupfuura radius yemuromo. Panguva imwe, saizi yediki yekupedzisira yemumhanyi mukuru inofanirawo kunge yakakura zvishoma pane saizi yegomba remhuno. Zviri nyore kurongedza muzzle

Kugadzirwa kwegating system chikamu chakakosha chekugadzirwa kwejekiseni mold. Iine simba rakananga pane jekiseni molding cycle uye kunaka kwezvikamu zvepurasitiki (sechitarisiko, zvinhu zvemuviri, kururama kwedimensional, Nekuti iyo IC tray ine huremu huremu).

Mitemo inotevera inofanirwa kutevedzwa pakugadzira
(1) Iyo cavity dhizaini nenzvimbo yekuvhura gedhi inofanirwa kunge yakaenzana kudzivirira mold kuti isaiswa pasi pemutoro usina kuenzana uye kukonzera kupenya..
(2) Kurongeka kwemakomba nemasuwo kunofanirwa kuderedza zviyero zvese zve mold zvakanyanya sezvinobvira.
(3) Iyo system inoyerera chiteshi inofanira kunge ipfupi sezvinobvira, uye hukuru hwemuchinjikwa hunofanira kunge hwakakodzera (diki zvakanyanya, kudzvinyirirwa uye kurasikirwa kwekupisa kuchava kukuru, uye yakakura kwazvo, kushandiswa kwepurasitiki kuchave kwakakura); kuderedza kukotama, uye kushata kwepamusoro kunofanirwa kuve kwakadzikira kuita kuti kupisa nekumanikidza kurasikirwa Kuve kudiki sezvinobvira.
(4) Kune akawanda cavities, iyo plastiki inonyunguduka inofanira kupinda mukati mekadzika uye makona ega yega yega panguva imwe chete sezvinobvira, ndizvo, vamhanyi vanofanira kurongwa nomutoo wakadzikama sezvinobvira
(5) Pamusana pekuti gomba rakazara, iyo vhoriyamu yekudurura system inofanirwa kuve diki sezvinobvira kuderedza kushandiswa kwepurasitiki.
(6) Nzvimbo yegedhi inofanira kunge yakakodzera, edza kudzivirira kukanganisa iyo yekuisa uye iyo diki core kudzivirira iyo core kubva pakukanganisa. Zviratidzo zvakasara zvegedhi hazvifaniri kukanganisa kuonekwa kwechikamu chepurasitiki.

Njodzi shanu yekupisa kwepamusoro kwe jekiseni kuumba muchina
Idzo njodzi huru shanu dzekukwira zvakanyanya tembiricha yemuchina wekuumba jekiseni ndidzo: thermal deformation yemuchina, yakaderedzwa mafuta viscosity, deformation yezvisimbiso zverubha, accelerated mafuta oxidation uye kuora, uye kuderedzwa kwechikamu chemhepo.

Imwe yenjodzi: thermal deformation yemuchina
Izvo zvikamu zvinofamba zvine akasiyana coefficients ekuwedzera kwekupisa muzvikamu zve hydraulic zvakanamira nekuda kwezvidiki zvadzo., kukonzera kusashanda zvakanaka, kukanganisa kufambiswa kwechokwadi kweiyo hydraulic system, uye kukanganisa kushanda kwehutano hwezvikamu.

Kukuvadza mbiri: kuderedza viscosity yemafuta
Kuwedzera tembiricha kukwira kwejekiseni rekuumba muchina kuchaita kuti viscosity yemafuta ideredze, kuwedzera kudonha, uye kushanda kwe volumetric yepombi uye kushanda kwehurongwa hwose huchaderedzwa zvakanyanya. Sezvo viscosity yemafuta inoderera, iyo firimu yemafuta yevhavha inotsvedza uye zvimwe zvikamu zvinofamba zvinova zvishoma uye zvakatemwa, uye kuramba kukwenya kunowedzera, zvichikonzera kuwedzera kupfeka.

Hazard 3: Deformation yezvisimbiso zverubha
Kuwedzera tembiricha kukwira kwejekiseni rekuumba muchina kuchakanganisa zvisimbiso zverabha, mhanyisa kutadza kukwegura, kuderedza kushanda kwekuisa chisimbiso uye hupenyu hwebasa, uye kukonzera kuvuza.

Hazard 4: Kurumidza iyo oxidation uye kuora kwemafuta
Kuwedzera tembiricha kukwira kwejekiseni rekuumba muchina kunomhanyisa oxidation uye kuparara kwemafuta., precipitate bituminous zvinhu, uye kuderedza hupenyu hwebasa remafuta ehydraulic. Iyo inonamira inovhara iyo inonyorova orifice uye slit valve port, zvichiita kuti vharafu yepressure inamire uye isakwanise kufamba, uye pombi yesimbi yakatambanudzwa uye yakagonya, kana kunyange kuputika.

Hazard 5: Zvinotungamirira kuhutano husina kunaka hwezvikamu
Kuwedzera kupisa kwekushisa kwe jekiseni kuumba muchina zvichaguma nekushaya kunaka kwekushanda kwezvikamu, uye mhepo yakanyungudika mumafuta ichapukunyuka, zvichiguma nehomwe dzemhepo, izvo zvichaderedza kushanda kwekushanda kwe hydraulic system. Iyo yakakodzera yekushanda tembiricha yeiyo hydraulic system inofanira kunge iri pakati 45 madhigiri uye 50 madhigirii. Icho chikonzero ndechekuti iyo hydraulic system yakagadzirirwa maererano neyakasarudzwa kumanikidza Ofic viscosity, Asi viscosity ichachinja nemhepo yekupisa mafuta, iyo ichakanganisa basa muhurongwa. Zvikamu, semafuta emazwi, Hydraulic mavhavha, Nekuti iyo IC tray ine huremu huremu, kuderedza kurongeka kwakakwana uye kupindura kwekupindura, Kunyanya kune chaiyo manyoro manhamba.

Panguva imwe, kana iyo tembiricha zvakanyanyisa, Iyo ichakurudzira kuchembera kwechisimbiso uye kuikonzera kuomesa uye kupenga; Kana tembiricha yakanyanya kuderera, simba rekugadzirisa richapedzwa uye kukurumidza kushanda kuchaderedzwa. Naizvozvo, Izvo zvinodikanwa kuti urege kutarisisa tembiricha yekushandira yehydraulic mafuta. Pane zvikonzero zvakawanda zvekudziya kwakanyanya kwemafuta, asi vazhinji vavo vari nekuda kwekutadza kweiyo redunhu remafuta kana kutadza kwehurongwa hwekutonhora.

Kana uine chero mibvunzo pa jekiseni kuumbwa ,plz sunungukai kubvunza FLYSE timu,tichakupa yakanakisa sevhisi!
