Zvikonzero zvekupfeka screw ye vertical injection molding muchina

Iyo jekiseni system ye vertical jekiseni kuumba muchina inoumbwa neplasticizing mudziyo uye mudziyo wekufambisa magetsi. Iyo jekiseni screw plasticizing mudziyo inonyanya kuumbwa nemudziyo wekudyisa, dhiramu, sikuruu, uye nozzle. Chishandiso chekufambisa magetsi chinosanganisira silinda yejekiseni, chigaro chejekiseni chinofambisa silinda uye screw Drive mudziyo.

The jekiseni sikuru inoshandiswa kwenguva yakareba pasi pekushisa kwepamusoro, high pressure, yakakwira mechanika torque uye yakakwirira friction nharaunda. Zvinhu zvishoma zvekutanga zvinodiwa nemamiriro ekugadzirisa, uye kupfeka kunokonzerwa nekukwesha hakudzivisiki. Kazhinji, sikururu yave pachena kune nitrogen yepamusoro. Kemikari kurapwa kuwedzera kuoma kwepamusoro, ndizvo, kunatsiridza kupfeka kuramba, asi kana zvikonzero zvekupfeka zvikafuratirwa uye kupfeka hakuedzi kuderedzwa zvakanyanya sezvinobvira, hupenyu hwekushanda hwe screw huchave huchadzikiswa zvakanyanya.

Zvinotevera zvinotsanangura zvikonzero yekupfeka kwejekiseni screw uye nzira dzekudzikisa kusakara
1. Plastiki yega yega ine yakanakira kugadzirisa tembiricha renji yeplasticization. Iyo tembiricha yekugadzira yebhari inofanirwa kudzorwa kuti ive padyo neiyo tembiricha renji. Ipurasitiki yegranular inopinda mubhodhoro kubva kune hopper, uye ichatanga kusvika kune chikamu chekudya, uye kukakavara kwakaoma kunozoitika muchikamu chekudyisa. Kana mapurasitiki aya asina kupisa zvakakwana uye kunyunguduka hakuna kuenzana, zviri nyore kukonzera kuwedzera kupfeka pamadziro emukati mebhodhoro uye pamusoro peiyo screw. Saizvozvowo, muchikamu chekumanikidza uye chikamu chehomogenization. Kana iyo yakanyungudutswa yepurasitiki yakakanganiswa uye isina kuenzana, zvichakonzerawo kuwedzera kupfeka.

2, kumhanya kunofanira kugadziriswa zvakanaka. Nekuti mamwe mapurasitiki anowedzerwa nemareinforcing agents, zvakadai segirazi fibers, minerals kana mamwe mafiritsi, kukweshana kwezvinhu izvi pazvinhu zvesimbi kunowanzova kukuru kupfuura kwepurasitiki yakanyungudutswa. Pakuumba jekiseni mapurasitiki aya, kana vakagadzirwa nekumhanya kukuru kwekutenderera, ichawedzera simba rekuveura kune epurasitiki, uye panguva imwe chete, iyo yekusimbisa ichagadzira yakawanda shredded fibers. Iyo shredded fibers ine magumo akapinza, kukonzera kupfeka Simba rinowedzera zvakanyanya, uye kukwenya mhedzisiro yemaminerari einorganic kana uchitsvedza pamusoro pesimbi pamusoro pekumhanya haisi diki, saka kumhanya hakufanirwe kugadziridzwa zvakanyanya.

Maitiro ekuvandudza hupenyu hwejekiseni screw
Iyo jekiseni screw inogona kushanda kwenguva yakareba pasi pekushisa kwakanyanya, high pressure, yakakwira mechanika torque uye yakakwirira friction nharaunda. Mamiriro ekugadzirisa anoda zvinhu izvi, uye kurasikirwa kunokonzerwa nekukwesha hakudzivisiki. Kazhinji, jekiseni screws anga ari pamusoro nitriding kurapwa kuwedzera pamusoro kuoma, ndizvo, kuvandudza kupfeka kusagadzikana. Zvisinei, kana chikonzero chekupfeka chisina kucheneswa uye kupfeka hakuna kuderedzwa, hupenyu hwesevhisi hwejekiseni screw huchapfupikiswa zvakanyanya. Zvikonzero zvekupfeka kwejekiseni screw uye nzira dzekudzikisa kusakara dzinotsanangurwa pazasi.

1.Plastiki yega yega ine yakanaka plasticizing tembiricha siyana. Iyo tembiricha yekugadzirisa yebhari inofanirwa kudzorwa padyo neiyo tembiricha yemhando. Granular plastiki inopinda mubhodhoro kubva kune hopper uye inotanga kusvika kunzvimbo yekudyisa. Dry friction inozoitika munzvimbo yekudyisa. Kana mapurasitiki aya asina kupisa zvakakwana uye akanyunguduka zvisina kufanana, ivo vanozokonzeresa kusakara kwakakura pamadziro emukati mebhari uye pamusoro peiyo jekiseni screw. Saizvozvowo, muchikamu chekumanikidza uye chikamu chehomogenization, kana iyo yakanyungudutswa yepurasitiki yakashata uye isina kuenzana, ichaitawo kuwedzera kupera kwejekiseni screw.
2. Kumhanya kunofanira kugadziriswa zvakakodzera. Nekuti mamwe mapurasitiki anowedzerwa nemareinforcing agents, zvakadai segirazi fibers, minerals kana mamwe mafiritsi. Iko kukweshera kwezvinhu izvi pamidziyo yesimbi kunowanzova kwakakura kudarika kwepurasitiki yakanyungudutswa. Kana mapurasitiki aya akaumbwa jekiseni, kana dzakagadzirwa nekumhanya kukuru kwekutenderera, uye panguva imwechete kuwedzera simba rekuveura papurasitiki, ichaitawo kuti kusimbiswa kubudise mafibhi akawanda akachekwa. Fiber yakachekwa ine migumo yakapinza, izvo zvinogona kukonzera kusakara pane jekiseni screw. Kana inorganic minerals inotsvedza pamusoro pesimbi pamusoro pekumhanya, scraping effect haisi diki, uye zvinokonzeresa kupera kweiyo jekiseni screw. Naizvozvo, kumhanya hakufanirwe kugadziridzwa zvakanyanya.

Basics of jekiseni Molding Process
Tembiricha, kumanikidzwa, kumhanya uye kutonhora kudzora zvinangwa, kushanda uye kunoguma kuti kugadziridzwa kwemajekiseni ekuumba muchina marongero anokanganisa maitiro uye mhando optimization screw control marongero akawanda-nhanho kuzadza uye akawanda-nhanho kurongedza kutonga.; Migumisiro yecrystallization, kwete-crystallization uye molecular / fiber alignment pane maitiro uye kunaka kwemukati kushushikana, kutonhora rate, plastiki shrinkage pane epurasitiki zvikamu zvemhando yepurasitiki rheology: kuti plastiki inoyerera sei, inogadzirisa uye inoshandura viscosity, hukama pakati pekugera uye molecular / fiber alignment. The ukama pakati pekudira hurongwa, kutonhora system, mold structure uye injection process

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