Maitiro ekudzikisa mushe inyaya yakajairika uye yakakosha mukugadzirwa kweakaumbwa silicone foam. Kudzikisira kwakashata kunogona kutungamira kune yakaderera kugadzirwa kwekuita, kubvarura chigadzirwa, deformation uye kunyangwe kuraswa. Kuti ugadzirise dambudziko iri, zvinofanirwa kutanga kubva kune masisitimu einjiniya maonero uye funga zvinhu zvitatu zvakakosha: molds, mold release agents, uye formula maitiro.
Natsiridza kushandiswa kwe mold release agents
1.Sarudza mhando yakakodzera ye mold release agent
Solvent{{0}based mold release agents: Izvo zvinonyanya kushandiswa, zvine firimu rakanaka-pakugadzira zvinhu, asi chenjedzo inofanira kubhadharwa kumhepo nekuchengetedzeka.
Mvura-based mold release agent: Yakanyanya kukoshesa zvakatipoteredza uye yakachengeteka, asi zvinotora nguva kuti iome uye zvinogona kukanganisa kugadzira.
Solvent{{0}free mold release agents (paste or wax form) : Inokodzera mold dzakaoma, nekusimba, asi inogona kukanganisa kupenya kwechigadzirwa. Kune silicone kupupa, zvakakosha kuti usarudze mold yekuburitsa mumiriri wakanyatsogadzirirwa silicone uye yakakodzera zvigadzirwa zvine furo. Zvisizvo zvekuburitsa zvigadziriso zvinogona kutungamira mukusawirirana, kurambidza vulcanization kana kuendesa kune chigadzirwa chepamusoro, zvichikanganisa kunotevera kugadzirisa (sekusunga, kupfapfaidza).
2.Nzira yakarurama yekuputira inokosha inokosha
Kuchenesa ndicho chinhu chekutanga chinodiwa: Usati wapfapfaidza iyo nyowani yekuburitsa mold, iyo mold mhango inofanirwa kucheneswa nejira rakapfava kana donje swab kubvisa chero yasara silicone uye mold inoburitsa tsvina.
Nheyo ye "kudya chikafu chidiki nguva zhinji" : Zviri nani kupfapfaidza yakaonda uye yakatsetseka nguva yega yega uye kuzviita kakawanda pane kupfapfaidza zvakanyanya panguva imwe. Iyo yakanyanya kukora layer ye mold release agent inoyerera ichipinda muvent plug uye ichisvibisa mold. Zvinotonyanya kukosha, zvinokonzeresa hurema hwakadai seorenji peel uye pinholes pane chigadzirwa chepamusoro uye kukanganisa kurongeka kwedimensional.
Uniform coverage: Shandisa pfuti yekupfapfaidza kuchengetedza imwe chinhambwe uye kuona kuti kona yega yega mold yakafukidzwa nefirimu rakatetepa zvakanyanya kuburikidza nekuchinjika-atomization. Nekunetsa-kusvika{3}}nzvimbo dzakaita semakomba akadzika uye mikaha yakatetepa, machira edonje anogona kushandiswa kubatsira mukuiswa. Kubatanidza nguva nenguva: Mushure mekunge mold shoma dzagadzirwa, ita nekukasira-kumwaya mushonga uku mold ichiri kudziya kuchengetedza mhedzisiro.
Yakakosha Solution: Mold Dhizaini uye Maintenance,
1.Surface kupera kwe mold
Kupenya kwepamusoro kwegomba rekuumbwa kunofanirwa kusvika pagiredhi repamusoro (senge mirror polishing #A1). Kutsvedzerera kwepasi, kudiki kwesimba rekukwenya uye kudzikisa kutsvedzerera. Kuma mold matsva kana kupfekwa, kurapwa kwepamusoro kunogona kutariswa, sekunge chromium plating: Iine kuoma kwepamusoro, nzvimbo yakatsetseka, uye haidzivirirwe necorrosion-, zvichiita kuti ive sarudzo inowanzoshandiswa uye inoshanda.
Teflon (PTFE) coating: Ine yakanaka kwazvo isina{0}}zvimiti zvekunamira uye inogona kuvandudza zvakanyanya kudhirowa, asi kusimba kwejasi racho kunoda kutariswa uye zvingada kugara ichiturika.
2.Zvinonzwisisika Draft Angle:
Iyo yekudhirowa Angle inofanirwa kuverengerwa pakugadzira mold. Kune zvinhu zvakapfava uye zviri nyore kugomara senge silicone furo, dhizaini Angle inofanirwa kuwedzerwa zvakafanira, kazhinji inokurudzirwa kuti ive isingasviki madhigirii matatu. Iyo yakakura kutsetseka, kudiki kudiki kwekupokana
3.Perfect mold chimiro:
Dzivisa zvakapesana-pasi: Mukugadzira, zvakakosha kudzivirira zvakapesana{1}pasi chimiro; kana zvisina kudaro, chigadzirwa chichave chakanyatsoputika.
Kugonesa ejection system: Ita shuwa kuti ejector mapini nemapureti ekusundidzira anoiswa pasimba rinonzwisisika{{0}kunotakura zvikamu zvechigadzirwa (senge mbabvu nenzvimbo dzakakora dzemadziro), uye kuti ejection yakatsetseka uye inoenderana. Iyo ejector pini pachayo inodawo kuve nekutsetseka kwakaringana uye yakakodzera dhizaini Angle.
Kugadziriswa kwakanaka kwemaitiro uye mafomula
Iyo vulcanization maitiro uye iyo rubber compound formula pachayo zvakare inopesvedzera zvakanyanya maitiro ekudzikisa.
1.Optimize vulcanization mamiriro:
Dzivisa overvulcanization: Overvulcanization inogona kuita iyo silicone rabha brittle, kuwedzera kunamatira kwayo kune mold, uye kutungamirira kumatambudziko mukudzikisa kana kubvarura. Nyatsodzora iyo vulcanization nguva uye tembiricha kuti uwane yakakwana vulcanization poindi.
Shandisa tembiricha yekuumbwa: Shanda payakanyanya kupisa tembiricha ye mold. Kazhinji, kana mold ichipisa zvakanyanya kana kutonhora zvakanyanya inokanganisa kudhirowa. Iyo yakagadzikana yekudzikisa tembiricha yemhando inogona kutsanangurwa mumitemo yemaitiro.
2.Check the rubber compound formula
Yemukati mold kuburitsa mumiriri: Taurirana nemupi wako wesilicone uye wedzera huwandu hwakakodzera hwemukati mold kuburitsa agent kune yerubha komboni. Inogona kutama kubva mukati ichienda kune iyo interface, ichitamba yebetsero yekudhonzesa basa, uye ine zvirinani synergistic mhedzisiro nevamiriri vekunze.
Vulcanization system: Zvikamu zvakasiyana-siyana zvinopisa (zvakadai seplatinum vulcanization vs. peroxide vulcanization) uye zvinowedzera zvinogona kukanganisa kusungirirwa kwekomboni yerubha kune mold. Kurukurai mukana wekuita zvakanaka-neinjiniya.
