Pulp molding, semumiriri wegirinhi wekurongedza, anofarirwa nevaridzi vemhando. Mukugadzira zvigadzirwa zvakaumbwa zve pulp, mold, sechinhu chakakosha, ine yakakwira tekinoroji zvinodiwa zvekusimudzira uye dhizaini, kudyara kwakanyanya, kutenderera kwenguva refu, uye njodzi yakanyanya. Saka, ndeapi mapoinzi akakosha uye ekudzivirira mukugadzirwa kwemapepa epurasitiki mold? Pazasi, isu tichagovana chimwe chiitiko mukurongedza dhizaini dhizaini kuti iwe udzidze uye uongorore pulp molding mold dhizaini.
01Kugadzira Mold
Chimiro chacho chine convex mold, concave mold, mesh mold, chigaro chekuumbwa, mold back cavity, uye kamuri yemhepo. Mesh mold ndiwo muviri mukuru weforoma. Sezvo mesh mold yakarukwa kubva kune simbi kana epurasitiki waya ine dhayamita ye0.15-0.25mm, haigone kuumbwa yakazvimiririra uye inofanirwa kusungirirwa pamusoro peiyo mold kuti ishande.
Iyo yekumashure mhango ye mold igomba rinoumbwa nehumwe gobvu uye chimiro chakanyatso wiriraniswa nenzvimbo yekushanda ye mold, maererano nechigaro che mold. The convex uye concave molds ideko rine imwe madziro ukobvu. Nzvimbo yekushanda ye mold yakabatanidzwa kumusana wekuseri nemakomba maduku akagoverwa zvakafanana.
Iyo mold inoiswa pane template yemuchina wekuumba kuburikidza nechigaro chekuumbwa, uye kamuri yemhepo yakaiswa kune rumwe rutivi rwetemplate. Iyo kamuri yemhepo yakabatana kune yekumashure mhango, uye kune zvakare maviri chiteshi chemhepo yakamanikidzwa uye vacuum pairi.
02Kuumba mold
Iyo yekuumba mold imold inopinda zvakananga mubepa rakanyorova risina chinhu mushure mekugadzira uye rine mabasa ekudziya, kumanikidza, uye kupera simba. Zvigadzirwa zvinogadzirwa ne mold yekugadzira zvine nzvimbo yakatsetseka, zviyero zvakaringana, kusimba, uye kusimba kwakanaka. Disposable tableware inogadzirwa uchishandisa mold iyi. Mukurongedzerwa kwemaindasitiri, zvimwe zvidiki, chaizvo, uye zvihombe zvezvinhu zvidiki zvakarongedzerwa dhizaini nedhizaini, zvine zvigadzirwa zvekurongedza zvinoshandiswa kuisa pakati pega rega. Kana zvigadzirwa zvakaumbwa zve pulp zvakashandiswa, zvinofanirwa kugadzirwa uchishandisa mold mold.
Nekudaro, akawanda maindasitiri ekurongedza zvigadzirwa zvinoshanda kune rimwe divi uye hazvidi kupisa kugadzika. Vanogona kuomeswa zvakananga. Mamiriro ekuumba mold anosanganisira convex mold, concave mold, mesh mold, uye heat element. Iyo convex kana concave mold ine mesh mold ine maburi emvura uye epositi. Panguva yekushanda, bepa rakanyorova risina chinhu rinotanga kusvinwa mukati mekugadzira mold, uye 20% yemvura inosvinwa uye inobudiswa. Panguva ino, mvura yemvura yepepa yakanyorova isina chinhu ndeye 50-55%, izvo zvinoita kuti mvura yakasara mushure mokunge bepa rakanyorova risina kuvharwa richipisa mukati memukumbo kuti rive vaporized uye ribudiswe. Iro bepa rakanyorova risina kuvharwa rinotsikirirwa, kuomeswa, uye kuumbwa kuita chigadzirwa.
Iyo mesh mold mukuumbwa inogona kukonzera mesh mamaki pamusoro pechigadzirwa, uye mesh mold inogona kukurumidza kukuvadza panguva yenguva zhinji extrusion. Kugadzirisa dambudziko iri, mugadziri we mold akagadzira mesh yemahara mold, iyo inogadzirwa nemhangura yakavakirwa spherical poda metallurgy. Mumakore maviri apfuura, mushure mekuvandudzwa kwemaitiro akawanda uye kusarudzwa kwehukuru hwehupfu hwehupfu hwakakodzera, hupenyu hwemesh free shape mold inogadzirwa ka10 iyo ye mesh mold, nekuderedza mutengo we50%. Zvigadzirwa zvemapepa zvinogadzirwa zvine hunyanzvi hwepamusoro uye hwakatsetseka hwemukati nekunze.
03Hot Pressing Mold
Mushure mekuoma, bepa rakanyorova risina chinhu rinopinda deformation. Kana zvimwe zvikamu zvikaita deformation yakanyanya kana kuti inoda kurongeka kwepamusoro mukutaridzika kwechigadzirwa, chigadzirwa chinopinda maitiro ekuumba, uye mold inoshandiswa inonzi shaping mold. Iyi mold inodawo zvinhu zvekudziya, asi inogona kuitwa pasina mesh mold. Zvigadzirwa zvinoda kuumbwa zvinofanirwa kuchengetedza hunyoro hwe25-30% panguva yekuomeswa kuitira kuti kuumbwa kuve nyore.
Muchiito chekugadzira, zvakaoma kudzora zvinyorwa zvemvura, izvo zvinoita kuti zvive zvakaoma kuti chigadzirwa chisangane nezvinodiwa zvehutano. Mugadziri akagadzira chifukidziro chekugadzira mold, uye maburi ekupfapfaidza anogadzirwa pane mold inoenderana nezvikamu zvinoda kuumbwa. Paunenge uchishanda, zvigadzirwa zvinoiswa mukugadzira mold mushure mekunyatsoomeswa. Panguva imwecheteyo, gomba rekupfapfaidza pane mold rinoshandiswa kupfapfaidza inopisa kudzvanya zvigadzirwa. Ichi mold chakada kufanana nesimbi yekupfapfaidza muindasitiri yezvipfeko.
04Kuendesa Mold
Iyo yekuchinjisa mold ndiyo yekupedzisira yekushanda kwemaitiro ese, uye basa rayo guru ndere kuendesa zvakachengeteka chigadzirwa kubva kune yakakosha yekubatsira mold kuenda kune yekugamuchira tireyi. Kune yekuchinjisa mold, dhizaini yayo inoda kuve yakapusa sezvinobvira, iine zvakaenzana zvakarongeka maburi ekusveta kuti ive nechokwadi chekuti chigadzirwa chinogona kushambadza zvakanaka pane mold pamusoro.
05Trimming Mold
Kuti ugadzire zvigadzirwa zvemapepa zvakachena uye zvakanaka, zvigadzirwa zvakaumbwa nepepa zvine zvinodiwa zvekutaridzika zvakashongedzerwa nematanho ekucheka. Die yekucheka molds inoshandiswa kuchekerera mipendero yakakasharara yezvigadzirwa zvakaumbwa nebepa, inozivikanwawo semapendero ekucheka mold.
