Maitiro ekugadzirisa jekiseni kuumbwa kupatsanurana pasi pevhu

Injection molding-parting surface burrs matambudziko uye pesvedzero yekuumba jekiseni maitiro pakubuda pachena kwePP zvigadzirwa.,unoziva kugadzirisa?
Nhasi ngatitaure nezvavo.
1. Mechanical equipment:
(1) The clamping force of the muchina wekuumba haina kukwana. Pakusarudza jekiseni molding muchina, iyo yakatemerwa clamping simba remuchina inofanirwa kunge yakakwira kupfuura tension inogadzirwa neiyo longitudinal inofungidzirwa nzvimbo yejekiseni yakaumbwa chigadzirwa panguva yejekiseni. Zvikasadaro zvinokonzeresa kuwedzera mold uye kupatsanura nzvimbo burrs..

(2) Iyo mold clamping mudziyo haina kunyatsogadziriswa, iyo toggle mechanism haina kutwasuka, uye kuruboshwe nekurudyi kana kumusoro uye pasi molds hazvina kuenzana, uye kufanana kweforoma hakugone kuwanikwa. Chiitiko chekuti rimwe divi re mold rakavharwa zvakasimba asi rimwe divi harina kunyatsobatanidzwa. , Pachave nekuparadzana kwepamusoro burrs panguva yejekiseni. To

(3) Iyo mold pachayo haina kufanana zvakanaka, kana kuiswa hakuenderane, kana template haina kufanana, kana kuti tension tsvimbo yakagoverwa zvisina kuenzana uye yakaremara. Izvi zvinokonzeresa kuti mold clamping ive isina kusimba uye iyo yekuparadzanisa nzvimbo burrs ichaonekwa. To

(4) Mhete isina kudzoka yakapfekwa zvakanyanya; chitubu chepfumbu chinopera; dhiramu kana screw inopfekwa zvakanyanya; iyo inlet inotonhorera system inotadza kukonzera “bhiriji” phenomenon; the barrel set jekiseni volume haikwani, cushion idiki, nezvimwewo. Inogona kuita kuti mabhura ekuparadzana aonekwe kakawanda, uye inofanira kugadziriswa kana kutsiviwa nenguva.

2. Mold aspect
Kusanyatsojeka kwe mold parting surface. Kusadzikama kwakashata kwesimbi ye mold kunokonzera mikaha kana mold yakavharwa, zvichiita kuti pave nemaburrs panzvimbo yekuparadzana. To

3. Process
(1) Simba rejekiseni rakanyanyisa kana kuti jekiseni rinomhanya zvakanyanya. Nekuda kweiyo high pressure uye high speed, simba rekuvhura pane mold rinowedzera uye rinokonzera kupenya. Iyo yekumhanyisa jekiseni uye nguva yejekiseni inofanirwa kugadziridzwa zvichienderana nehupamhi hwechigadzirwa. Chigadzirwa chakaonda chinofanira kuzadzwa nekukurumidza nekukurumidza, uye hapana jekiseni mushure mekunge yazadzwa; chigadzirwa chakakora chinofanira kuzadzwa nekumhanya kwakaderera. To

(2) Kunyanya kudyisa vhoriyamu kunokonzeresa maburrs panzvimbo yekuparadzana. Zvakakosha kucherechedza kuti usaise jekiseni yakanyanyisa kunyunguduka kuitira kudzivirira kuora mwoyo, kuitira kuti kuora mwoyo kurege kuva “akazadzwa”, asi mabhura ekuparadzana achaonekwa. Mamiriro ezvinhu aya anofanira kugadziriswa nekuwedzera nguva yejekiseni kana nguva yekubata. To

(3) Kunyanya kupisa kwembiya uye nozzle kana yakanyanya kupisa mold kunoderedza viscosity yepurasitiki uye kuwedzera fluidity.izvo zvinokonzeresa maburrs panzvimbo yekuparadzanisa pasi pemamiriro ekupinda zvakanaka mu mold..
4. Panyaya yezvigadzirwa
(1) Kana iyo plastiki viscosity yakanyanya kana yakaderera, panogona kunge paine mabhura ekuparadzana. Plastiki ine yakaderera viscosity, zvakadai senaironi, polyethylene, polypropylene, Nekuti iyo IC tray ine huremu huremu, inofanira kuwedzera clamping simba;

mapurasitiki ane kunyura kwemvura kwakasimba kana mapurasitiki anobata mvura anoderedza zvakanyanya kuyerera kweviscosity pakupisa kwakanyanya uye kuwedzera mukana wekuparadzanisa mabhura epasi Kune aya mapurasitiki., zvinofanira kunyatsoomeswa; iyo viscosity yemapurasitiki akasanganiswa nezvinhu zvakawandisa zvakagadziridzwa zvakare inoderera, uye kana zvakakodzera, zadzisa zvikamu zvakachengetwa. Plastiki

Kana iyo viscosity yezvinhu yakanyanya kukwirira, kuyerera kupikisa kuchawedzera, uye hukuru hwekudzokera shure huchawedzera kudzvinyirira kwegomba, zvichikonzera kusakwana simba rekusunga uye kugadzira mabhura ekuparadzana. To

(2) Husina kuenzana saizi yepurasitiki mbishi zvinhu zvinoita kuti huwandu hwekudya husiyane, uye mabhura ekuparadzana achaonekwa.

Kufurira kwe jekiseni kuumbwa process pa kujeka kwezvinhu zvePP
Kujeka kwezvakajeka zvepolypropylene zvigadzirwa zvakagadziridzwa neyakajeka nucleating agent haina hukama chete nemhando ye plastiki mbishi zvinhu pacharo, asi zvakare yakanyatsoenderana nekusarudzwa kwejekiseni molding process mamiriro.

Kuwana zvakanakisisa jekiseni kuumbwa Mamiriro ezvinhu ezvigadzirwa zvinogoneka mukuwedzera pachena kugona kwezvinhu zvakasvibirira uye kuwana yakanakira yakajeka polypropylene zvigadzirwa.. Izvi zvine kukosha kwakanaka kumakambani ezvigadzirwa zvepurasitiki.

Kupesvedzera zvinhu zvePP pachena:

(1) Iyo yakakwirira tembiricha yekunyungudika, kukwirisa mhute ye random copolymer polypropylene isina transparent nucleating agent uye zvakanyanya kujeka.

(2) Mhedzisiro yekunyungudika tembiricha pamhute ye random copolymer polypropylene nemhando dzakasiyana dze transparent nucleating agents ine chekuita nemhando dze nucleating agents..

(3) Zvezvigadzirwa zvinogona kuratidza zvizere anti-reflection mhedzisiro ye transparent nucleating agent pane yakaderera kunyungudika tembiricha., mhute ichasimuka zvishoma nezvishoma nekukwira kwekushisa kwekunyunguduka, asi huwandu hwekuchinja hwakakura kupfuura hweiyo isiri-nucleating agent. Iyo yakasarudzika copolymer polypropylene idiki zvakanyanya.

(4) Iyo yakaderera tembiricha yekuumbwa, iyo yakaderera mhute yepolypropylene yakajeka uye yakakwirira kujeka.

(5) Iyo inokurumidza kukurumidza jekiseni, iyo yakakwirira mhute yepolypropylene yakajeka uye yakaderera kujeka.

(6) Nekuwedzera kwenguva yekubata, mhute yepolypropylene yakajeka inoderera, uye mushure mokunge vasvika pamuganhu, inoramba isina kuchinjwa.

(7) Sezvo simba rekubata rinowedzera, mhute yepolypropylene yakajeka inoderera, asi kana iyo yekubata pressure yakanyanya, chigadzirwa chichava nekupenya, uye kusara kwemukati kunetseka kwechigadzirwa kuchavawo kwakakura.
