Michina yekugadzira jekiseni repurasitiki michina inopisa nekusanganisa mapeti epurasitiki kudzamara anyungudutswa kuita mvura, iyo inozotumirwa kuburikidza nesiruu uye kumanikidzirwa nemuburi rekubuda kuita mold kuti dzisimbe sezvikamu zvepurasitiki.
Kune mana emhando dzemhando dzemakina ekuumba, akaiswa padivi pesimba rinoshandiswa kubaya purasitiki: hydraulic, magetsi, hybrid hydraulic-electric, uye mechaniki jekiseni molder.Michina yeHydraulic, inoshandisa mota dzemagetsi kusimba mapombi ehydraulic, yaive yekutanga mhando yemajekiseni epurasitiki ekuumba michina.Ruzhinji rwemajekiseni ekuumba majekiseni achiri rudzi urwu.Nekudaro, magetsi, hybrid, uye muchina wemuchina une humbowo hwakanyanya.Majekiseni emagetsi molders, achishandisa magetsi-powered servo motors, anopedza simba shoma, pamwe nekunyarara uye nekukurumidza.Nekudaro, iwo zvakare anodhura kupfuura hydraulic michina.Michina yeHybrid inoshandisa huwandu hwesimba semhando dzemagetsi, zvichitsamira pane inoshanduka-simba AC dhiraivha inosanganisa ese ari maviri hydraulic nemagetsi mota madhiraivha.Chekupedzisira, machina emuchina anowedzera tonnage pane clamp kuburikidza nedhisheni system kuti ive nechokwadi chekuti kupenya hakupinde muzvikamu zvakasimbiswa.Ose ari maviri aya nemichina yemagetsi yakanakira basa rakachena remukamuri sezvo pasina njodzi yekudonha kwehydraulic system.
Imwe neimwe yemhando dzemuchina uyu inoshanda zvakanyanya kune akasiyana maficha, zvisinei.Michina yemagetsi ndiyo yakanakira kurongeka, nepo michina yehybrid inopa simba rekurovera rakawanda.Hydraulic muchina unoshandawo zvirinani pane mamwe marudzi ekugadzirwa kwezvikamu zvakakura.
Pamusoro pemhando idzi, michina inouya mumhando dzakasiyana-siyana kubva pa5-4,000 matani, ayo anoshandiswa zvichienderana nekupenya kwepurasitiki uye zvikamu zvichaitwa.Michina inonyanya kushandiswa, zvisinei, ndeye 110 ton kana 250 ton machines.Paavhareji, majekiseni makuru ekuumba majekiseni anogona kudhura kubva pamadhora makumi mashanu- $ 200,000 kana kupfuura.3,000 matani michina inogona kuita $700,000.Kune rumwe rutivi rwechikero, muchina wekugadzira jekiseni redesktop une matani mashanu esimba unogona kuita pakati pemadhora makumi matatu nemakumi mashanu nemazana mashanu.
Kazhinji chitoro chemuchina chinongoshandisa mhando imwe chete yemuchina wekugadzira jekiseni, sezvo zvikamu zviri zvega kune imwe neimwe mhando- zvinodhura zvakanyanya kuchinja kubva kune imwe mhando kuenda kune imwe (kunze kune izvi zvikamu zve mold, izvo zvinoenderana nemhando dzakasiyana. michina yema brand ichaita mamwe mabasa zvirinani pane mamwe.
Nheyo dzePlastiki Injection Molding Machines
Izvo zvekutanga zvePlastiki jekiseni rekugadzira michina ine zvikamu zvitatu zvikuru: jekiseni unit, mold, uye clamping/ejector unit.Isu tinotarisisa pane jekiseni mold mudziyo wemidziyo muzvikamu zvinotevera, izvo zvinoputsika mukati sprue uye mumhanyi system, magedhi, hafu mbiri dzegomba remuvhu, uye sarudzo yedivi zviito.Iwe unogona kudzidza zvakawanda nezve maitiro epurasitiki jekiseni rekugadzira mabhesi kuburikidza neyakadzama yedu chinyorwa Plastic Injection Molding Basics.
1. Mold Cavity
Mold cavity inowanzove nemativi maviri: A side uye B side.Iyo musimboti (B Side) inowanzova isiri-yekuzora, yemukati divi rine ejection mapini anosundira chikamu chakapedzwa kubva muforoma.Gomba (A Side) ndiyo hafu yeforoma inozadzwa nepurasitiki yakanyungudutswa.Mold cavities kazhinji ine maburi ekubvumira mhepo kubuda, iyo yaizowedzera kupisa uye kukonzera kupisa mavanga pazvikamu zvepurasitiki.
2. Runner System
Runner system inzira inobatanidza iyo yakanyungudutswa yepurasitiki zvinhu kubva kune screw feed kune chikamu chegomba.Mune inotonhora mumhanyi mold, plastiki inoomesa mukati meanomhanya chiteshi pamwe nechikamu cavities.Kana zvikamu zvabviswa, vamhanyi vanodzingwa zvakare.Vanomhanya vanogona kuchekwa kuburikidza nemaitiro emaoko sekucheka nemafa cutters.Mamwe masisitimu anotonhora anomhanya anoburitsa otomatiki vamhanyi uye anopatsanura zvakasiyana achishandisa matatu-ndiro mold, apo mumhanyi anogovaniswa nendiro yekuwedzera pakati penzvimbo yejekiseni negedhi rechikamu.
Maumbirwo anopisa anomhanya haaburitse vamhanyi vakanamatira nekuti zvinhu zvekudyisa zvinochengetwa zvakanyungudutswa kusvika kugedhi rechikamu.Dzimwe nguva inodaidzwa kuti "madonhwe anopisa," inopisa mumhanyi system inoderedza marara uye inosimudzira kudzora kuumbwa pakuwedzera mari yekushandisa.
3. Sprues
Sprues ndiyo chiteshi inopinda nepurasitiki yakanyungudutswa kubva mumuromo, uye ivo vanowanzo pindirana nemumhanyi anoenda kugedhi uko ipurasitiki inopinda mumakomba ekuumbwa.Iyo sprue yakakura dhayamita chiteshi pane mumhanyi chiteshi inobvumira huwandu hwakakodzera hwezvinhu kuyerera kubva mujekiseni unit.Mufananidzo 2 pazasi unoratidza paive nesprue yechikamu mold pakanga paine imwe purasitiki yakasimbiswa ipapo.
A sprue akananga mumucheto gedhi rechikamu.Iyo perpendicular maficha anonzi "inotonhora slugs" uye anobatsira kudzora zvinhu shear kupinda gedhi.
4. Magedhi
Gedhi kaburi kadiki mumudziyo unobvumira purasitiki yakanyungudutswa kupinda mugomba remuvhu.Nzvimbo dzemagedhi dzinowanzo onekwa pachikamu chakaumbwa uye dzinoonekwa sediki rough chigamba kana dimple-senge chimiro chinozivikanwa sechivharo chegedhi.Kune marudzi akasiyana-siyana emagedhi, rimwe nerimwe rine simba raro uye kutengeserana.
5. Mutsara wokuparadzanisa
Mutsetse mukuru wekuparadzana wechikamu chakaumbwa chejekiseni chinoumbwa kana mold halves mbiri dzaswedera pamwechete kuti dzijekiseni.Iro mutsara mutete wepurasitiki unotenderera kunze kwedhayamita yechikamu.
6. Zviito zveparutivi
Zviitiko zveparutivi zviiswa zvinowedzerwa kune mold inobvumira zvinhu kuyerera zvakatenderedza kuti zvigadzire iyo undercut ficha.Zviito zveparutivi zvinofanirwa kubvumirawo kubuda kwakabudirira kwechikamu, kudzivirira kukiya kukiya, kana mamiriro ezvinhu apo chikamu kana chishandiso chinofanira kukuvara kubvisa chikamu.Nekuti zviito zvepadivi hazviteedzere iyo general tool direction, undercut features inoda madraft angles akanangana nekufamba kwechiito.Verenga zvakawanda pamusoro pemhando dzakajairika dzezviito zvepadivi uye nei zvichishandiswa.
Kune akareruka A uye B molds asina chero undercut geometry, chishandiso chinogona kuvhara, kuumba, uye kuburitsa chikamu pasina akawedzera maitiro.Nekudaro, zvikamu zvakawanda zvine madhizaini ekugadzira anoda danho repadivi kuburitsa maficha senge kuvhurika, tambo, tabo, kana zvimwe zvinhu.Zviito zveparutivi zvinogadzira mitsara yekuparadzanisa yechipiri.
