1, Dhizaini yekutanga kuchinja ndiyo kiyi

Nezve auto air & water tank product mold, kudzora mhando yedhizaini nekugadzira kwakaoma kupfuura mhando yakajairika, sezvo zvikamu zverudzi urwu zvinowanzoumbwa nezvinhu zvePA6 (PA66) + GF (30-35%), uye rudzi urwu rwezvinhu zviri nyore kuwana deformation panguva yekuumbwa, uye saizi yechigadzirwa inoenderana iri nyore kusashivirira. Saka, kana uchiziva kugadzika kwayo, saka kugadzira pre-deformation design zvichibva pane zvakaitika uye CAE analysis zvinoguma nekutanga kwekugadzira kwave kiyi yekubudirira kwekugadzira mold.

Chikwata cheEnuo mold chine ruzivo rwemakore anopfuura gumi pakugadzira mold isati yatanga, uye chakashandira Valeo, Mahle-behr, Delphi nevamwe vatengi vane mukurumbira pasi rose vezvikamu zvemota. Pano tinokuzivisai muchidimbu ruzivo rwedu pakugadzira mold yemota yemhepo nemvura. Zvirokwazvo, makambani akasiyana ane maitiro akasiyana, kana muverengi anodiwa aine maonero akasiyana, tinogamuchirawo neushamwari kuti mutaure nesu.

2, Kuongorora mifananidzo yezvikamu, kujekesa nzvimbo dzakakosha dzechigadzirwa nehukuru

Kuti unzwisise nzvimbo dzakakosha dzechigadzirwa uye saizi dzakabatana nadzo nguva dzose ndiyo danho rekutanga apo mifananidzo yezvigadzirwa zvevatengi yasvika, saka nyatsoteerera kukosha kwacho, senge "Kuguma kwechinhu" ("Kuguma kwechinhu" kwaidiwa zvakanyanya kutwasuka, kutsamira uye kushivirira saizi yechimiro, uye zvimwe zvikamu zvehukuru hwechigadzirwa zvichatevera kuchinja kwadzo) "Nzvimbo yeTube orifice" (hukuru hwe "tube orifice" hwakakoshawo, kazhinji nzvimbo, cylindrical uye dimension tolerances zvinodiwa) uye mbabvu dzechigadzirwa "Boss" uye "U-shape" nezvimwewo, zvinoratidzwa pazasi:

Kana paine chakuvhuvhu chitsva, gadzirai chigadziriso chepakutanga pachigadzirwa (muchiita "kubhadhara zvinhu" pane imwe nzira yakatarisana nekuchinja kwakafungidzirwa pachine nguva zvichienderana neruzivo uye ongororo yeCAE, rongai kuti zvigadziriswe mushure mekunge kuchinja kwacho kwaitwa). Mushure mekuyedza chakuvhuvhu, gadzirai shanduko diki zvichibva pakuchinja chaiko kwechigadzirwa, kugadzirisa magadzirirwo epurasitiki, chimiro nenzvimbo nezvimwewo.

3, Kudhirowa zvigadzirwa.

Kuti zvive nyore kugadzirisa mold mune ramangwana, kudhirowa data idzva re3D chigadzirwa isu pachedu zvichienderana nezvigadzirwa zvemutengi kwakakosha (zviyero zvakakosha zvinofanira kuchengetedzwa). Kuona kukosha kwedeformation yezvigadzirwa, pamwe nekuongorora mold flow analysis uye ruzivo rwekugadzirisa data rezvigadzirwa, pazasi unogona kuona maitiro edeformation ane ruzivo:

Pano, mamwe mazano anofadza kugoverwa panguva yekudhirowa patsva, akadai se: tanga uchidhirowa nzvimbo ye "Base end surface", zvichienderana ne deformation value kuti udhirowe kutwasuka, flatness curve pamucheto wechigadzirwa, tarisa ma curves iwayo ku "Stretch" (UG command) straightness surface. Nzvimbo dzakatwasuka dzinoitwa ne "Border" (UG command). Danho iri rakakosha, kuti zvive nyore kuchinja mune ramangwana, dhirowa curve kutanga, usatambanudze "UG command" zvakananga, wobva washandisa deformation surface yekutwasuka kuti uwane chimiro chechigadzirwa ne "Offset" (UG command). Kuti udzivise kuchinja zvikamu zvakawanda zve mold panguva ye mold inotevera, kucheka zvinhu zvepurasitiki panzvimbo ye "Base end surface" yechigadzirwa, wozozvidzosera muT1-T3 modification zvichibva pa deformation chaiyo yechigadzirwa (pamwe nepurasitiki).

Mazano ekubhadhara anobatsira:

1. Musatevedzera pamusoro peprofile yezvigadzirwa zvevatengi zvakanyanya sezvinobvira, edzai kuzvidhirowa mega. Kuti, kune zvinotevera, kugadzirisa mold kuve nyore kuchinjwa, kusanganisira ukobvu hwemadziro. Kana maumbirwo acho akakopwa kubva kuzvigadzirwa zvevatengi, mushure mekugadzirisa kakawanda, data re3D richawana kukanganiswa.
2. Mukuita kwekudhirowa, tarisa data remutengi re2/3D kuti rirege kusiyana.

4, Maitiro ekuchinja anogona kuitika nezvechikamu chakakosha chechigadzirwa

1, Kushanduka kwechigadzirwa "Base end surface"

Nepose pazvinogoneka kuderedza chiito papurasitiki pakutanga, zvinogona kudzivirira kudzokorodza zvikamu zvemold zvakanyanya sezvinobvira. Mutsetse mutsvuku uri pazasi unoratidza mafambiro ekufungidzira kwekushanduka kwechigadzirwa. Ndapota cherechedza kuti mbabvu dze "Boss" kana "U-shaped" kana zvinhu zvine chekuita nazvo zvinofanirwa kutamiswa pamwe chete ne "Base end surface" (Zvimwe zvezvinhu zviri pasi peboss zvinodzika pasi ne0.5mm, uye "Boss" inofanirawo kudzika pasi ne0.5), wozodhirowa zvimwe. Zvinokurudzirwa kushandisa "surface" (UG command) kuti udhirowe.

2, Kuchinja kwechigadzirwa che "Tube orifice"

Chimiro che "R" radius chiri pamudzi wechubhu chinofanira kunge chakafanana nedata rezvigadzirwa zvevatengi, sezvo iyi "R" radius ichikanganisa simba renzvimbo yakakosha yechigadzirwa. Mumamiriro ezvinhu akajairwa, chubhu yakatenderera inofanira kuderedzwa purasitiki parutivi, yozochinja kukosha zvichienderana nekushanduka chaiko, kune chubhu yakakura, chimiro chechubhu chinogona kugadzirwa sechimiro cheoval pachine nguva.

3, chigadzirwa che "U" chimiro chepurasitiki chinoshanduka

Plastiki ye "U-shape" inofanirawo kuita shanduko yemadhigirii 2-3, nzvimbo yepakati yembabvu dze "U-shape" inofanirawo kucheka zvinhu padivi (mufananidzo 1). Mushure mekunge zvigadzirwa zvese zvadhirowa zvakanaka uye wobva wagadzira radius ye "R" (uye kuti zvive nyore kuchinja, dzimwe nguva kugadzira radius ye "R" kunokundikana kana kuti kunotora nguva yakareba), kana mamwe ma geometry mu data revatengi re3D asina kukanganiswa, tinogona kuaparadzanisa kana asina kukanganisa kuungana kwezvikamu (vatengi vazhinji vanoda kuti chimiro chakapinza chive chamfered ne "R" radius). Pamusoro pezvo, mamwe ma geometry akajeka pamuviri mukuru wechigadzirwa akakura, rudzi urwu rwekushanduka kwechigadzirwa runofanira kutarisisa zvakanyanya pakuenzanisa uye kutenderera (mufananidzo 2).

5, Mhedziso

Pamusoro apa pane ruzivo rwedu pakugadzira mold ye "mold" yemuchina we "air & water" - "easy deformation". Tichipedza danho iri zvakanaka, ndinofunga kuti hafu yekubudirira kwekugadzirwa kwemold dzakadaro kwaizowanikwa, saka imwe hafu iri kupi? Ndapota onai chikamu chinotevera chechinyorwa chino "Unoziva here kugadzira mold isati yatanga deformation?" vhiki rinouya.
Zvakanaka, vaverengi vanodikanwa. Ndatenda zvikuru nenguva yenyu yekuverenga pano. Ndiri kutarisira kukuonai muchikamu chinotevera!
