JekiseniMudziyo
Mudziyo wejekiseni chishandiso chinoita kuti resin inyungudiswe nekupisa uye kubaiwa muforoma.Sezvinoratidzwa mumufananidzo, resin inosvinwa mubhodhoro kubva kumusoro wezvinhu, uye iyo yakanyunguduka inotakurwa kumucheto wepamberi webhari nekutenderera kwe screw.Mukuita ikoko, iyo resin zvinhu mudhiramu inopisa nekupisa pasi pechiito cheheater, uye resin inonyungudutswa pasi pechiito cheshear stress ye screw, uye resin yakanyungudutswa inoenderana nechigadzirwa chakaumbwa, iyo huru inoyerera. gwara uye gwara rebazi rinochengetwa.Pamberi pechigubhu (chinonzi metering), kufamba kunoenderera mberi kwescrew kunopinza zvinhu mumhango ye mold.Kana iyo resin yakanyungudutswa ichiyerera muforoma, kumhanya kwekufamba (jekiseni kumhanya) kwescrew kunofanirwa kudzorwa, uye kudzvanywa (kubata kumanikidza) kunoshandiswa kudzora mushure mekunge resin yazadza mold.Kana iyo screw chinzvimbo uye jekiseni kudzvanywa kwasvika kune imwe kukosha, isu tinokwanisa kushandura iyo yekumhanyisa kudzora kune kudzvinyirira kutonga.
Mold Maintenance
1. Bhizinesi rekugadzirisa rinofanira kutanga ragadzirira imwe neimwe ye molds nekadhi rekutanga rekodha uye kuverenga kushandiswa kwayo, kutarisira (kuzora, kuchenesa, kudzivirira ngura) uye kukanganisa zvakadzama.Kubva pane izvi, inogona kuona kuti ndezvipi zvikamu uye zvikamu zvakakuvadzwa uye chiyero chekupfeka.Ipa ruzivo rwekutsvaga nekugadzirisa matambudziko, pamwe nemaitiro ekuumba maparamendi e mold, uye zvinhu zvinoshandiswa muchigadzirwa kupfupisa nguva yekuedza ye mold uye kuvandudza hunyanzvi hwekugadzira.
2. Kambani yekugadzira inofanira kuedza zvinhu zvakasiyana-siyana zvemuumbi pasi pekushanda kwakajairika kwejekiseni rekuumba muchina uye mold, uye kuyera hukuru hwekupedzisira yakaumbwa chikamu chepurasitiki.Kuburikidza neruzivo urwu, mamiriro azvino ekuumbwa anogona kutsanangurwa, uye mhango nepakati zvinogona kuwanikwa., Kutonhora kwegadziriro uye nzvimbo yekuparadzanisa, nezvimwewo, maererano nemashoko anopiwa nezvikamu zvepurasitiki, mamiriro ekukuvadza emuumbi uye matanho ekugadzirisa anogona kutongwa.
3. Tarisa pakutsvaga uye kuongororwa kwezvikamu zvakakosha zvakakosha zvemuumbi: ejector uye zvikamu zvinotungamirira zvinoshandiswa kuti zvive nechokwadi chekuzarura nekuvhara kufamba kwechimiro uye ejection yechikamu chepurasitiki.Kana chero chikamu che mold chakanamira nekuda kwekukuvara, chinoita kuti kugadzirwa kumire.Gara uchichengeta mold thimble uye inotungamira positi yakaomeswa (iyo yakanyatsokodzera lubricant inofanira kusarudzwa), uye gara uchitarisa kana iyo thimble, inotungamira post, nezvimwewo zvakaremara uye kukuvara kwepasi.Kana yangowanikwa, idzore nenguva;mushure mekupedza kutenderera kwekugadzira, mold inofanirwa kunge iri Iyo nzvimbo yekushanda, inofamba uye inotungamira zvikamu zvakaputirwa nehunyanzvi anti-ngura mafuta, uye kunyanya kutarisisa kunofanirwa kubhadharwa kune kuchengetedzwa kwesimba elastic rezvikamu zvinotakura zvegiya, rack mold. uye chitubu mold kuti vave nechokwadi chokuti vanogara vari mumamiriro ekushanda akanaka;Nekufamba kwenguva, chiteshi chekutonhodza chinowanzoisa chiyero, ngura, silt, uye algae, izvo zvinoderedza chikamu chemuchinjiko chegedhi yekutonhora uye nekudzikisa chiteshi chekutonhora, icho chinoderedza zvakanyanya mwero wekupisa pakati peinotonhorera uye mold, uye inowedzera mutengo wekugadzira webhizinesi.
Naizvozvo, iyo convection chiteshi Kucheneswa kweanopisa mumhanyi mold kunofanirwa kutariswa;kune inopisa mumhanyi mold, kuchengetedza kwekudziya uye kutonga system kunobatsira kudzivirira kuitika kwekukundikana kwekugadzira, saka inonyanya kukosha.Nokudaro, mushure mekutenderera kwega kwega kwekugadzira, bhandi rinopisa, rod heaters, kupisa probes uye thermocouples pane mold inofanira kuyerwa neohmmeter.Kana dzakakuvadzwa, dzinofanirwa kutsiviwa nenguva uye kuongororwa nenhoroondo yekuumbwa.Enzanisa uye chengeta zvinyorwa kuitira kuti matambudziko aonekwe nenguva uye matanho ekupikisa anogona kutorwa.
4. Ngwarira kuchengetwa kwepamusoro kwe mold.Iyo inobata zvakananga hutano hwepamusoro hwechigadzirwa.Chinangwa chiri pakudzivirira ngura.Nokudaro, zvinonyanya kukosha kusarudza yakakodzera, yepamusoro-soro, uye inyanzvi anti-rust mafuta.Mushure mekunge mold yapedza basa rekugadzira, nzira dzakasiyana dzinofanirwa kushandiswa kunyatso bvisa yakasara jekiseni molding zvinoenderana neyakasiyana jekiseni molding.Tsvimbo dzemhangura, waya dzemhangura uye nyanzvi dzekuchenesa mold dzinogona kushandiswa kubvisa yasara jekiseni kuumba uye mamwe madhipoziti muforoma, uyezve mhepo yakaoma.Zvinorambidzwa kuchenesa zvinhu zvakaoma sewaya dzesimbi nemasimbi kuti usakwenya pamusoro.Kana paine ngura dzinokonzerwa nekuumbwa kwejekiseni rinokuvadza, shandisa guyo kukuya nekukwenenzvera, uye pfapfaidza oiri yenyanzvi yekudzivirira ngura, wozochengeta mold panzvimbo yakaoma, inotonhorera, uye isina guruva.
