Zoyambira za Pulasitiki jakisoni Kumangira
Onani njira yopangira jakisoni ndi momwe imagwirira ntchito.
Kumangira jakisoni wa pulasitiki ndi njira yotchuka yopangira momwe ma pellets a thermoplastic amasinthidwa kukhala magawo ambiri ovuta. Njira yopangira jekeseni ndi yoyenera pazinthu zosiyanasiyana zapulasitiki ndipo ndizofunikira kwambiri pa moyo wamakono-milandu ya foni, nyumba zamagetsi, zoseweretsa, ngakhale zida zamagalimoto sizikanatheka popanda izo. Nkhaniyi ifotokoza zoyambira pakuumba jekeseni, kufotokoza momwe jekeseni imagwirira ntchito, ndikuwonetsa momwe zimasiyana ndi kusindikiza kwa 3D.
Kodi Zoyambira Zopangira Majekeseni Apulasitiki Ndi Chiyani?
Zofunikira pakuumba jekeseni wa pulasitiki zimaphatikizapo kupanga kapangidwe kazinthu, kupanga chikombole kuti chigwirizane ndi kapangidwe kazinthu, kusungunula ma pellets apulasitiki, ndikugwiritsa ntchito kukakamiza kubaya ma pellets osungunuka mu nkhungu.
Onani tsatanetsatane wa sitepe iliyonse pansipa:
1. Kupanga Zopangira Zopangira
Okonza (mainjiniya, mabizinesi opanga nkhungu, ndi zina zotero) amapanga gawo (monga fayilo ya CAD kapena mtundu wina wosunthika), kutsatira malangizo ofunikira pakupanga jekeseni. Opanga ayesetse kuphatikiza izi pamapangidwe awo kuti athandizire kukulitsa kupambana kwa nkhungu ya jakisoni wa pulasitiki:
* Mabwana oyika / zomangira ulusi
*Kukhuthala kosalekeza kapena pafupi kosalekeza
* Kusintha kosalala pakati pa makulidwe osiyanasiyana a khoma
* Mabowo opanda kanthu m'magawo okhuthala
* Mitundu yozungulira
* Sinthani ma angles pamakoma oyimirira
* Nthiti zothandizira
*Kukwanirana kwa mkangano, ma snap-fit olowa, ndi zinthu zina zomwe sizimangirira
*Mahinji okhala
Kuphatikiza apo, opanga amayenera kuchepetsa zinthu zotsatirazi kuti achepetse zolakwika pamapangidwe awo:
*Kukhuthala kwa makoma osafanana kapena makamaka makoma owonda/okhuthala
*Makoma oyimirira opanda ngodya zojambulira
* Kusintha kwadzidzidzi kwa geometrical (makona, mabowo, ndi zina)
* Kujambula kosapangidwa bwino
* Kudulira kwapansi / kuphatikizika
2. Kupanga Tooling Mold kuti igwirizane ndi Product Design
Akatswiri aluso komanso opanga zida, pogwiritsa ntchito kapangidwe kazinthu, amapanga nkhungu yopangira makina opangira jakisoni. Chombo chopangira zida (chomwe chimatchedwanso kuti chida) ndi mtima ndi moyo wa makina opangira jakisoni. Amapangidwa mwaluso kuti akhale ndi ziboliboli zoyipa pamapangidwe azinthu ndi zina zowonjezera monga ma sprues, othamanga, zipata, ma vents, makina otulutsa, njira zozizirira, ndi zida zosuntha. Zida zopangira zida zimapangidwa ndi zitsulo ndi aluminiyamu zomwe zimatha kupirira zikwi makumi (ndipo nthawi zina zikwi mazana) za kutentha ndi kuzizira, monga 6063 aluminium, P20 chitsulo, H13 chitsulo, ndi 420 zitsulo zosapanga dzimbiri. Ntchito yopangira nkhungu imatenga milungu yopitilira 20 kuti ithe, kuphatikiza kupanga ndi kuvomereza, zomwe zimapangitsa kuti sitepeyi ikhale yotalikirapo kwambiri pakuumba jekeseni. Ndilonso gawo lokwera mtengo kwambiri la jekeseni, ndipo chikombole cha zida chikapangidwa, sichingasinthidwe kwambiri popanda kuwononga ndalama zowonjezera.
3. Kusungunula Pulasitiki Resin Pellets
Ogwira ntchito atapeza nkhungu yomalizidwa, imayikidwa mu makina opangira jakisoni, ndipo nkhunguyo imatseka, kuyambitsa kuzungulira kwa jekeseni.
Ma granules a pulasitiki amalowetsedwa mu hopper ndi mbiya. Zomangira zomwe zimabwereranso zimakokedwa kumbuyo, kulola kuti zida zilowerere pakati pa screw ndi mbiya. Chomangiracho chimagwera kutsogolo, ndikukankhira zinthuzo mu mbiya ndikuyandikira mabande a chotenthetsera pomwe chimasungunuka kukhala pulasitiki yosungunuka. Kutentha kosungunuka kumasungidwa kosasintha malinga ndi momwe zinthu ziliri kuti zisawonongeke mu mbiya kapena nkhungu yokha.
4. Kugwiritsa Ntchito Kukakamiza Kulowetsa Ma Pellets Osungunuka mu Nkhungu
Zowononga zimakakamiza pulasitiki yosungunukayi kudzera mumphuno, yomwe imakhala mkati mwa nkhungu yotchedwa mold sprue bushing. Kuthamanga kwa platen kumagwirizana ndi nkhungu ndi nozzle pamodzi mwamphamvu, kuonetsetsa kuti palibe pulasitiki yomwe ingatuluke. Pulasitiki yosungunuka imapanikizidwa ndi njirayi, zomwe zimapangitsa kuti zilowe m'madera onse a nkhungu ndikuchotsa mpweya wotuluka kudzera muzitsulo za nkhungu.
Jekeseni Woumba Makina Ophatikiza
Zigawo zamakina omangira jakisoni ndi monga hopper, mbiya, zomangira zobwerezabwereza, chotenthetsera(s), platen yosunthika, nozzle, nkhungu, ndi chibowo cha nkhungu.
Zambiri pazachigawo chilichonse cha jekeseni pamndandanda womwe uli pansipa:
* Mphepete: potsegula kumene zitsulo zapulasitiki zimalowetsedwa mu makina.
*Mgolo: nyumba yakunja ya makina omangira jekeseni, yomwe ili ndi wononga zobwerezabwereza ndi ma granules apulasitiki. Chitsulocho chimakulungidwa m'magulu angapo a chotenthetsera ndipo chimakutidwa ndi nozzle yotentha.
*Kubwereza kobwerezabwereza: chigawo cha corkscrew chomwe chimapereka ndi kukakamiza zinthu zapulasitiki pamene zimasungunuka mu mbiya.
* Ma heater: Amadziwikanso kuti magulu otenthetsera, zigawozi zimapereka mphamvu zotentha ku ma granules apulasitiki, kuwatembenuza kuchokera ku mawonekedwe olimba kupita kumadzi. mawonekedwe.
*Mbale Wosuntha: Chigawo chosuntha cholumikizidwa ndi pakatikati pa nkhungu chomwe chimagwira ntchito kukakamiza kuti ma theka onse awiri asalowe ndi nkhungu ndikutulutsanso pachimake cha nkhungu powulula gawo lomwe lamalizidwa.
*Nozzle: chigawo chotenthetsera chomwe chimapereka njira yotulutsira pulasitiki yosungunuka mu nkhungu, kusunga kutentha ndi kukakamizidwa kukhala kokhazikika momwe zingathere.
*Mvula: chigawo kapena zigawo zomwe zili ndi nkhungu ndi zina zothandizira monga zikhomo za ejector, njira zothamanga, njira zoziziritsira, mpweya, ndi zina zotero. Pang'ono, nkhungu zimagawidwa m'magawo awiri: mbali yokhazikika (pafupi ndi mbiya) ndi nkhungu. pachimake (pa mbale yosuntha).
* Mphuno ya Mold: malo oyipa omwe, akadzazidwa ndi pulasitiki yosungunuka, amaupanga kukhala gawo lomaliza lomwe mukufuna kuphatikiza zothandizira, zipata, othamanga, sprues, ndi zina zambiri.
Kodi jekeseni Woumba Imagwira Ntchito Motani?
Pamene pulasitiki yadzaza nkhungu kuphatikizapo sprues, othamanga, zipata, ndi zina zotero, nkhunguyo imasungidwa pa kutentha kwapadera kuti ilole kulimbitsa yunifolomu kwa zinthuzo mu mawonekedwe a gawo. Kupanikizika kumasungidwa pamene kuziziritsa kuti zonse zisiye kubwerera mumgolo ndikuchepetsa kuchepa. Panthawiyi, ma granules ambiri apulasitiki amawonjezeredwa ku hopper poyembekezera kuzungulira kotsatira (kapena kuwombera). Ikazizira, mbale imatsegulidwa ndikulola kuti gawo lomwe lamalizidwa litulutsidwe, ndipo zomangirazo zimakokedwanso, kulola kuti zinthu zilowe mu mbiya ndikuyambanso ntchitoyo.
Kuzungulira kwa jekeseni kumagwira ntchito mopitilira izi - kutseka nkhungu, kudyetsa / kutentha ma granules a pulasitiki, kuwakakamiza mu nkhungu, kuziziritsa kukhala gawo lolimba, kutulutsa gawolo, ndi kutseka nkhungu kachiwiri. Dongosololi limalola kupanga zida zapulasitiki mwachangu, ndipo zida zapulasitiki zopitilira 10,000 zitha kupangidwa tsiku logwira ntchito kutengera kapangidwe kake, kukula kwake, ndi zinthu.
Djmolding ndi otsika voliyumu jekeseni akamaumba makampani mu china.Our pulasitiki jekeseni akamaumba ndondomeko umabala prototypes mwambo ndi mbali kupanga mapeto ntchito ndi nthawi kutsogolera mofulumira monga tsiku 1, otsika buku pulasitiki jekeseni akamaumba gawo katundu kwa 10000 mbali pachaka.
