Maitiro ekutenga yakakodzera china jekiseni

Kazhinji kutaura, Vazhinji vevatengi vanga vari vanga vari mujekiseni rekuumba maindasitiri kwemakore mazhinji, vane kugona kuzvitonga uye kusarudza zvakakodzera china jekiseni muchina kugadzira. Zvisinei, Mune zvimwe zviitiko, mutengi angangoda rubatsiro rwemugadziri pakusarudza kuti ndeupi muchina wekuumba jekiseni wokushandisa, kana kunyange mutengi anogona kungova nesample kana zano rechigadzirwa obva abvunza mugadziri. kana muchina unogona kugadzirwa kana kuti ndeupi modhi inofananidzwa.

Pamusoro pe, zvimwe zvakakosha zvigadzirwa zvingada michina yakakosha zvakadai sekumanikidza kuunganidza, zvishwe zvakavharwa, jekiseni compression, Nekuti iyo IC tray ine huremu huremu, kuti igadzirwe zvine hunyanzvi. Zvinogona kuoneka kuti nzira yekuona yakakodzera jekiseni rekugadzira muchina kuburitsa mubvunzo wakanyanya kukosha. Mashoko anotevera anopiwa kuitira kuti vaverengi varerukirwe.

Zvinhu zvakakosha izvo zvinowanzokanganisa kusarudzwa kwemushini wejekiseni zvinosanganisira mold, zvigadzirwa, mapurasitiki, kuumba zvinodiwa, nezvimwewo. Naizvozvo, ruzivo runotevera runofanira kuunganidzwa kana kuwanikwa musati maita sarudzo:

◆ Mold saizi (width, urefu, ukobvu), uremu, special design, nezvimwewo. ;

◆ Rudzi uye huwandu hwepurasitiki kushandiswa (chinhu chimwe chete mbishi kana mapurasitiki akati wandei);

Saizi yekuonekwa (urefu, width, urefu, ukobvu), uremu, nezvimwewo. jekiseni rakaumbwa chigadzirwa;

Mushure mekuwana ruzivo rwepamusoro, unogona kutevera matanho ari pasi apa kuti usarudze muchina wakakodzera jekiseni:1. Sarudza muenzaniso wakanaka: iyo modhi uye yakatevedzana zvinoenderana nechigadzirwa uye epurasitiki. Nekuti kune akawanda marudzi echina jekiseni michina, zvinodikanwa kuti uone nenzira kwayo kuti ndeipi jekiseni rekugadzira muchina kana nhevedzano chigadzirwa chinofanira kutanga kugadzirwa, seyakajairika thermoplastic kana bakelite raw materials kana PET raw materials. Color, maviri-mavara, multicolor, interlayer kana ruvara rwakasanganiswa, nezvimwewo. Pamusoro pe, zvimwe zvigadzirwa zvinoda mamiriro akadai kugadzikana kwepamusoro (rakavharwa loop), kururama kwepamusoro, moto wakanyanya, high firing pressure kana kukurumidza kugadzirwa (multi-loop), uye nhevedzano yakakodzera inofanirawo kusarudzwa kuti igadzirwe.

2. Inogona kuiswa pasi: saizi ye mold inosarudza kana iyo “hombe mbiru mukati chinhambwe”, “mold thick”, “saizi shoma yekuumbwa” uye “mold plate size” yemuchina akakodzera kuve nechokwadi chekuti mold inogona kuiswa pasi.

◆ The hupamhi uye urefu hwe mold inofanira kuva isingasviki kana kuti rutivi rumwe rudiki pane chinhambwe chemukati chembiru huru;

◆ Hupamhi nehurefu hwemuumbi hunofanirwa kuenderana nehukuru hushoma hunokurudzirwa nemuchina wekuumba jekiseni uye idiki zvikuru..

3. Inogona kuwanikwa: mold uye chigadzirwa chekupedzisira chinotarisa kana “mold kuvhura shamhu” uye “mold strokes” zvakakwana kubvisa chigadzirwa chekupedzisira.

◆ Kurohwa kwekuvhura kwemuumbi kunofanira kunge kwakapetwa kaviri kureba kwechigadzirwa chekupedzisira munzira yekuvhura nekuvhara kwe mold., uye kureba kwekuumbwa kunofanira kubatanidzwa;

4. Iyo clamping unit inogona kukiya jekiseni muchina unofanirwa kupa zvakakwana “clamping force” kudzivirira mold kuti isavhurwe. Iko kuverenga kwe clamping simba rinodiwa ndeiyi inotevera:

◆ Verenga nzvimbo yakarongedzerwa yechigadzirwa chakapedzwa munzira yekuchinja mold kubva pakukura kwekuonekwa kwechigadzirwa chakapedzwa.;

◆Mould rutsigiro simba = inofungidzirwa nzvimbo yechigadzirwa chakapedzwa munzira yekuchinja mold (cm2) × nhamba ye mold cavities × kumanikidzwa mu mold (kg/cm2);

◆Kumanikidzwa mu mold kunosiyana neyakagadzirwa, uye iyo yakawanda mbishi zvinhu i350 ~ 400kg/cm2;

◆Kusunga simba remuchina kunofanirwa kunge kwakakura kudarika simba rekusunga, uye nokuda kwokuchengeteka, iyo clamping simba remuchina kazhinji 1.17 nguva huru kudarika simba rekusunga.

5. Full shot: Sarudza zvinodiwa “jekiseni volume” kubva pahuremu hwechigadzirwa chakapedzwa uye nhamba yefodya cavities uye sarudza zvakakodzera “screw diameter”.

◆Nhamba ye mold cavities (imwe mold uye makomba akawanda) inofanira kutariswa pakuverenga uremu hwechigadzirwa chakapedzwa;

◆Nekuda kwekugadzikana, huwandu hwejekiseni hunofanira kuva 1.35 nguva dzehuremu hwechigadzirwa chakapedzwa, ndizvo, uremu hwechigadzirwa chakapedzwa hunofanira kunge huri mukati 75% yehuwandu hwejekiseni.

6. Jekiseni rakanaka: mamiriro e “screw compression ratio” uye “saka iyo yese jekiseni molding process Yekugadzirwa kwezvinhu mbishi” zvinotemerwa nepurasitiki. Mamwe mapurasitiki einjiniya anoda yakakwira jekiseni kudzvanywa uye yakakodzera screw compression ratio dhizaini kuti ive nani ekuumba mhedzisiro. Naizvozvo, kuitira kuti chigadzirwa chakapedzwa chipfurwe zviri nani, iyo jekiseni pressure inodiwa uye compression ratio nyaya dzinofanirawo kutariswa pakusarudza screw. .

7.7. Kupfura nekukurumidza: uye kusimbiswa kwe “kumhanya kupfura”. Zvimwe zvinogadzirwa zvigadzirwa zvinoda yakakwira jekiseni chiyero uye nekukurumidza jekiseni kune yakagadzikana kuumbwa, dzakadai senge-Ultra-yakatetepa apedza zvigadzirwa. Mune ino kesi, zvingave zvichidikanwa kuti uone kana jekiseni chiyero uye chiyero chejekiseni remuchina chakakwana, uye kunyangwe ichida kuve yakaomeswa nemagetsi ekuunganidza, yakavharika-chiuno kudzora uye zvimwe zvigadzirwa. Kazhinji kutaura, pasi pemamiriro akafanana, sikuruu inogona kupa yakakwira jekiseni kumanikidza kazhinji ine yakaderera kupfura kumhanya, pane kudaro, sikuruu inogona kupa yakaderera jekiseni kumanikidza kazhinji ine yakakwira kupfura kumhanya. Naizvozvo, pakusarudza sikuruu dhayamita, huwandu hwejekiseni, jekiseni kumanikidza uye jekiseni chiyero (jekiseni kumhanya) inoda kuyambuka-kutariswa uye kusarudzwa.

Pamusoro pe, dhizaini-yakasarudzika dhizaini inogona zvakare kushandiswa kupfupisa iyo nguva yekuumba nezvienzanisirwa zviumbwa zvemubatanidzwa. Mushure mematanho ari pamusoro, musimboti, jekiseni Kuumbwa muchina unosangana nezvinodiwa kunogona kutsanangurwa, asi pane zvimwe zvakakosha zvinofanirwa kutariswa:

◆Dambudziko rekuenzanisa saizi:

Pasi pemamwe mamiriro akasarudzika, chakuvhe chemutengi kana chigadzirwa chinogona kunge chiine chiumbwa chidiki asi huwandu hukuru hwepfuti, kana hukuru hukuru hukuru asi hushoma hwepfuti. Mune ino kesi, iwo marongero akajairwa akagadzwa nemugadziri anogona kunge asingawanikwe. Kusangana nezvinodiwa nevatengi, zvinonzi “saizi inoenderana” inofanira kuitwa, ndizvo, “rakakura madziro diki pfuti” kana “diki dura rakakura kupfura”. Izvo zvinonzi “madziro mahombe uye diki jekiseni” zvinoreva chepakutanga standard clamping die unit ine diki jekiseni sikuruu. Kwete, iyo “diki madziro uye hombe jekiseni” zvinoreva chepakutanga standard clamping unit ine hombe jekiseni sikuruu. Ehe saizvozvo, panogona kuve nematanho akatiwandei emusiyano pakati pechando clamping uye jekiseni.

Mukushandisa chaiko, vatengi vanowedzera vachakumbira kutenga izvo zvinonzi “yakakwira-mhanyisa muchina” kana “muchina wekukurumidza”. Kazhinji kutaura, kuwedzera kune izvo zvinodikanwa zvechigadzirwa pachako, mazhinji ezvinangwa kupfupisa kuumbwa kutenderera uye kuwedzera goho pauniti nguva, nokudaro kudzikisa kugadzirwa kwemitengo uye kugadzirisa kukwikwidza. Kazhinji, kuzadzisa chinangwa chataurwa pamusoro, kune nzira dzakawanda:

1. Speed ​​up the jekiseni kumhanya: wedzera mota nepombi, kana kuwedzera yekumanikidza yekuunganidza (zviri nani kuvhara loop control);
2. Kurumidza kukurumidza kudyisa: kuwedzera mota uye pombi, kana kuderedza iyo yekudyisa hydraulic mota kuti ikurumidze iyo yekumhanya kumhanya;
3. Multi-loop system: inotora kaviri-loop kana matatu-loop dhizaini kuita zviito zvakasanganiswa panguva imwe chete kupfupisa nguva yekuumba;
4. Wedzera nzira yemvura yekuumbwa kuti uvandudze kutonhora kweiyo mold.
