Kana muchina wejekiseni uchishandiswa, kudzvanywa kuri pamusoro pescuru kana sikururu painotenderera nekudzokera kunonzi plasticizing pressure, inozivikanwawo se back pressure.Ukuru hwekumanikidza uku hunogona kugadziriswa nevhavha yekuyamura mu hydraulic system.

 

Ejector: Iyo ejector inosundira ejector ndiro kuti ifambise iyo ejector waya silinda yakagadzikwa pane ejector ndiro, uye inosundira zvikamu zvepurasitiki (zvigadzirwa) uye inorasa kunze kwegomba remuvhu kana core kuti iwane mhedzisiro yekudhirowa.Iyo ejector tsvimbo inowanzobudiswa.Izvo zvimiro zvinogona kushandiswa ejection zvinosanganisirawo push plates, jacking pombi, nezvimwe.

Push chubhu: Iyo push chubhu inoshandiswawo kusundira kunze chigadzirwa.Inowanzo shandiswa munzvimbo dzakadai semaburi maburi uye mbiru kubatsira kudhiza.

 

Push chubhu: Iyo push chubhu inoshandiswawo kusundira kunze chigadzirwa.Inowanzo shandiswa munzvimbo dzakadai semaburi maburi uye mbiru kubatsira kudhiza.

 

Ejector: Kukuvadzwa kwepamusoro kweiyo ejector idiki kune chikamu chepurasitiki, uye inokodzera mamiriro ezvinhu apo chikamu cheiyo ejection chine chaiyo uye pamusoro pezvinodiwa.

 

Mujekiseni, saizi yeplasticizing pressure inoda kuchinjwa nedhizaini yescrew, zvinodiwa zvemhando yechigadzirwa uye rudzi rwepurasitiki.Kana aya mamiriro uye kumhanya kwekutenderera kwe screw inoramba isina kuchinjika, kuwedzera kumanikidza kweplasticizing kuchasimbisa kuveura.Mhedzisiro ndeyekuwedzera tembiricha yekunyunguduka, asi inoderedza kugona kwepurasitiki, kuwedzera reverse kuyerera uye kuyerera kwekudonha, uye kuwedzera simba rekutyaira.

 

Uye zvakare, kuwedzera kumanikidza kweplasticizing kunogona kuita kuti tembiricha yeyunifomu yakanyunguduka, kusanganiswa kweruvara kuve yunifomu, uye gasi riri mukunyunguduka rinogona kuburitswa.Mukushanda kwakawanda, sarudzo yeplasticizing pressure inofanira kunge yakaderera sezvinobvira pane chirevo chekuona kunaka kwechigadzirwa.Kukosha kwakananga kunosiyana nemhando dzakasiyana dzemapurasitiki anoshandiswa, asi kazhinji haawanzopfuura 20 kg / cm².

 

Ruzivo rwakawedzerwa:

 

Iyo nguva inodiwa kuti upedze jekiseni yekuumba maitiro inonzi molding cycle, inozivikanwawo seye molding cycle.Izvo chaizvo zvinosanganisira zvinotevera zvikamu:

 

Molding kutenderera: Kutenderera kutenderera kunokanganisa zvakananga kugadzirwa kwevashandi uye kushandiswa kwemidziyo.Naizvozvo, mukuita kwekugadzira, iyo nguva yakakodzera mukutenderera kutenderera inofanirwa kupfupikiswa zvakanyanya sezvinobvira pasi pechikonzero chekusimbisa kunaka.Muchikamu chese chekuumba, nguva yejekiseni uye nguva yekutonhora ndiyo inonyanya kukosha, vane simba rinogadzirisa pamhando yechigadzirwa.

 

Nguva yekuzadza munguva yejekiseni yakanangana nechiyero chekuzadza, uye nguva yekuzadza mukugadzira inowanzoita 3-5 masekondi.Kumanikidza kubata nguva munguva yejekiseni ndiyo nguva yekumanikidza yepurasitiki mugomba, iyo inoverengera chikamu chikuru chenguva yese yejekiseni, kazhinji anenge 20-120 masekondi (iyo yakawedzera gobvu zvikamu zvinogona kunge zvakakwira se5-10. maminitsi).
