mmene kusankha jekeseni akamaumba makina

Pali ma templates awiri pa makina jekeseni akamaumba, imodzi sikuyenda, amatchedwa fixed template; winayo akhoza kusunthidwa, amatchedwa template yosuntha. Chikombolecho chimayikidwa pazithunzi ziwirizo ndi zomangira ndi kusindikiza mbale motsatira. Nkhungu ikatsegulidwa, template yosunthika ya makina omangira jekeseni imasuntha, potero kuyendetsa nkhungu kutsegula.

Pambuyo pa nkhungu amapangidwa, m'pofunika kuchita jekeseni akamaumba, valani makina opangira jekeseni, ndikuyamba kupanga zinthu. Komabe, pali mitundu yambiri yamakina opangira jekeseni, ndipo makina aliwonse opangira jekeseni ali ndi magawo ake. Chojambula chojambula chiyenera kukwaniritsa zofunikira za makina opangira jekeseni operekedwa ndi kasitomala, ngati sichingathe kutulutsa. Kuti

Pali zambiri mapangidwe magawo makina opangira jekeseni. Zotsatirazi zidzayang'ana pazigawo zingapo zokhudzana ndi nkhungu. Ndikuyembekeza kuti owerenga adzamvetsera ku mapangidwe enieni a nkhungu. Kuti

1. Kuchuluka kwa jekeseni
Voliyumu ya jakisoni ndiye kuchuluka kwake kwakukulu (kapena kuchuluka kwa voliyumu) kuti makina opangira jekeseni amatha kuwombera nthawi imodzi panthawi yopanga, ndipo imayimira kuchuluka kwa jekeseni wamtundu uwu wa makina opangira jekeseni. Kuchuluka kwa kusungunula komwe kumagwiritsidwa ntchito mu nkhungu yopangidwira ndikocheperako kuposa kuchuluka kwa jekeseni wa makina opangira jekeseni. Apo ayi, mankhwala sakhutira ndipo sangathe kupangidwa. Kuti

2. Clamping mphamvu
Chimene chinachitika chinali kukakamiza kwa makina opangira jekeseni pa template pamene nkhungu idatsekedwa. Mphamvu yolumikizira yomwe imafunikira pakupanga chinthucho pakuwumba iyenera kukhala yocheperako kuposa mphamvu yolumikizira ya makina osankhidwa ajakisoni.. Apo ayi, guluu wosungunula amatha kuchoka pamalo olekanitsa mosavuta, kung'anima.

3. Kutalikirana kwa ndodo
Pali ndodo zinayi zomangira m'makona akufa a template yokhazikika ndi template yosunthika ya makina omangira jekeseni.. Ntchito yawo ndikuwonetsetsa kuti makina opangira jekeseni ali ndi mphamvu zokwanira komanso zolimba, ndipo nthawi yomweyo ndi udindo kutsetsereka template. Komabe, zimakonda kuchepetsa kukula kwa nkhungu, chifukwa nkhungu imakwezedwa kuchokera pakati pa ndodo yomangirira pakuyika. Kuti

Miyeso ya nkhungu singakhale yaikulu kuposa mtunda pakati pa ndodo zomangira. If the length of the mold exceeds the distance between the tie rods, check whether the mold is hoisted into the rod workshop by rotating. If the rotary hoisting cannot be carried out, then the mold size can only be changed. , Or replace the injection molding machine. Kuti

4. Nozzle size check
The nozzle head of the injection molding machine is generally spherical. When selecting the sprue sleeve, the spherical radius of the sprue sleeve should be consistent with the spherical radius of the nozzle. In order to prevent the high-pressure melt from overflowing from the contact gap between the nozzle and the sprue sleeve, the spherical radius of the sprue sleeve should generally be larger than the nozzle radius. Nthawi yomweyo, kukula kwa mapeto ang'onoang'ono a wothamanga wamkulu ayeneranso kukhala wamkulu pang'ono kuposa kukula kwa dzenje la nozzle. Zosavuta kugwirizanitsa mphuno

Mapangidwe a gating system ndi gawo lofunikira la mapangidwe a nkhungu ya jekeseni. Zimakhudza mwachindunji kayendedwe ka jekeseni komanso ubwino wa zigawo zapulasitiki (monga maonekedwe, katundu wakuthupi, kulondola kwa dimensional, etc.).

Mfundo zotsatirazi ziyenera kutsatiridwa popanga
(1) Maonekedwe a kabowo ndi malo otsegulira zipata ziyenera kukhala zofananira kuti nkhungu zisamangidwe ndi katundu wosagwirizana ndikupangitsa kuwala..
(2) Kukonzekera kwa mapanga ndi zitseko ziyenera kuchepetsa kukula kwa nkhungu momwe zingathere.
(3) Njira yoyendetsera dongosolo iyenera kukhala yayifupi momwe mungathere, ndi kukula kwapang'onopang'ono kuyenera kukhala koyenera (chochepa kwambiri, kuthamanga ndi kutaya kutentha kudzakhala kwakukulu, ndi chachikulu kwambiri, kugwiritsa ntchito pulasitiki kudzakhala kwakukulu); kuchepetsa kupindika, ndipo khwimbi la pamwamba liyenera kukhala lochepa kuti kutentha ndi kupanikizika kutayike Kukhale kochepa momwe zingathere.
(4) Kwa ma cavities angapo, kusungunuka kwa pulasitiki kumayenera kulowa kuya ndi kumakona a patsekeke iliyonse panthawi imodzimodzi momwe zingathere, ndiye, othamangawo ayenera kukonzedwa m’njira yolinganizika mmene angathere
(5) Pa mfundo yakuti patsekeke wadzaza, kuchuluka kwa dongosolo lothira kuyenera kukhala kochepa momwe mungathere kuti muchepetse kugwiritsa ntchito pulasitiki.
(6) Malo a pachipata ayenera kukhala oyenera, yesetsani kupewa kukhudza choyikapo ndi pachimake chaching'ono kuti mupewe kupunduka pakati. Zizindikiro zotsalira za chipata siziyenera kukhudza maonekedwe a gawo la pulasitiki.

Zowopsa zisanu kutentha kwakukulu kwa makina jekeseni akamaumba
Zowopsa zisanu zazikulu zakukwera kwambiri kwa kutentha kwa makina omangira jekeseni ndi: matenthedwe matenthedwe makina, kuchepetsa kukhuthala kwa mafuta, kusinthika kwa zisindikizo za mphira, Kuchuluka kwa mafuta oxidation ndi kuwonongeka, ndi kuchepetsa mphamvu ya chigawo cha mpweya.

Chimodzi mwa zoopsa: matenthedwe matenthedwe makina
Zigawo zosuntha zokhala ndi ma coefficients osiyanasiyana akukula kwamafuta m'zigawo za hydraulic zimakakamira chifukwa chocheperako., kuchititsa malfunctions, kukhudza kulondola kwa kufalikira kwa ma hydraulic system, ndi kuwonongeka kwa magwiridwe antchito a magawo.

Kuwononga ziwiri: kuchepetsa mamasukidwe akayendedwe a mafuta
Kutentha kwambiri kwa makina omangira jekeseni kumapangitsa kuti kukhuthala kwamafuta kuchepe, onjezerani kutayikira, ndi mphamvu ya volumetric ya mpope ndi mphamvu ya dongosolo lonse zidzachepetsedwa kwambiri. Pamene mamasukidwe akayendedwe a mafuta amachepetsa, filimu yamafuta ya valve yotsetsereka ndi mbali zina zosuntha zimakhala zowonda komanso zodulidwa, ndipo kukana kukangana kumawonjezeka, kumabweretsa kuchuluka kwa mavalidwe.

Zowopsa 3: Kusintha kwa zisindikizo za rabara
Kutentha kwakukulu kwa makina opangira jekeseni kumasokoneza zisindikizo za rabara, onjezerani kulephera kwa ukalamba, kuchepetsa ntchito yosindikiza ndi moyo wautumiki, ndi kuyambitsa kutayikira.

Zowopsa 4: Imathandizira makutidwe ndi okosijeni komanso kuwonongeka kwa mafuta
Kutentha kwakukulu kwa makina omangira jekeseni kumafulumizitsa makutidwe ndi okosijeni ndi kuwonongeka kwa mafuta., kutulutsa zinthu za bituminous, ndikuchepetsa moyo wautumiki wamafuta a hydraulic. Madziwo amalepheretsa kutuluka kwa madzi ndi khomo la valve, kupangitsa kuti valavu yopondereza ikakamire ndikulephera kusuntha, ndipo chitoliro chachitsulo chatambasulidwa ndi kupindika, kapena ngakhale kusweka.

Zowopsa 5: Kupangitsa kuti pakhale kusagwira bwino ntchito kwa zigawo
Kutentha kwakukulu kwa kutentha makina jekeseni akamaumba zidzapangitsa kuti ziwalozo zisamagwire bwino ntchito, ndipo mpweya wosungunuka m'mafuta udzatuluka, kumabweretsa matumba a mpweya, zomwe zidzachepetsa magwiridwe antchito a hydraulic system. Kutentha koyenera kogwira ntchito kwa hydraulic system kuyenera kukhala pakati 45 madigiri ndi 50 madigiri. Chifukwa chake ndikuti ma hydraulic system amapangidwa molingana ndi kukakamizidwa kwamafuta amakulidwe osankhidwa, koma mamasukidwe akayendedwe adzasintha ndi kutentha mafuta, zomwe zidzakhudza ntchito mu dongosolo. Zigawo, monga masilinda amafuta, ma hydraulic valves, etc., kuchepetsa kulondola kwa kuwongolera ndi kukhudzidwa kwa mayankho, makamaka makina ojambulira olondola.

Nthawi yomweyo, ngati ndi kutentha wakwera kwambiri, idzafulumizitsa kukalamba kwa chisindikizo ndikuchipangitsa kuumitsa ndi kung'ambika; ngati kutentha kuli kochepa kwambiri, mphamvu yogwiritsira ntchito idzagwiritsidwa ntchito ndipo liwiro la ntchito lidzachepetsedwa. Chifukwa chake, m'pofunika kumvetsera kwambiri kutentha kwa hydraulic mafuta. Pali zifukwa zambiri za kutentha kwa mafuta, koma ambiri a iwo ndi chifukwa cha kulephera kwa kayendedwe ka mafuta kapena kulephera kwa dongosolo lozizira.

Ngati muli ndi mafunso pa jekeseni akamaumba ,plz khalani omasuka kufunsa Gulu la FLYSE,tidzakupatsani utumiki wabwino kwambiri!
