Mukuita kweMachininguye jekiseni molding kugadzirwa, iyo yakabatanidzwa sisitimu, isinga patsanurwe.
Mukuumbwa kwejekiseni, iyo gating system inoreva chikamu chemumhanyi purasitiki isati yapinda mugomba kubva mumhuno, kusanganisira mumhanyi mukuru, inotonhora zvinhu mhango, mumhanyi uye gedhi, nezvimwe.
Iyo yekudira system inonziwo runner system.Iyo seti yematanho ekudyisa anotungamira epurasitiki kunyunguduka kubva mumuromo wejekiseni muchina kuenda kugomba.Kazhinji inoumbwa nemumhanyi mukuru, mumhanyi, gedhi uye gomba rezvinhu zvinotonhora.Iyo yakanangana nemhando yekuumba uye kugona kwekugadzira kwezvigadzirwa zvepurasitiki.
Jekiseni Mold Main mugwagwa:
Inzira iri mu mold inobatanidza muromo wejekiseni rekuumba muchina kune mumhanyi kana mhango.Pamusoro pesprue pane concave kuti ibatane nemuromo.Iyo dhayamita yeinopinza mumhanyi mumhanyi inofanira kunge yakakura zvishoma pane dhayamita yenozzle (0.8mm) kudzivirira kufashukira uye kudzivirira maviri kubva kuvharika nekuda kwekubatana kusiri iko.Iyo dhayamita yeinopinza inoenderana nehukuru hwechigadzirwa, kazhinji 4-8mm.Iyo dhayamita yemumhanyi mukuru inofanira kuwedzerwa mukati nekona ye 3 ° kusvika 5 ° kufambisa kuderedzwa kweanomhanya.
Cold Slug:
Igomba riri kumagumo emumhanyi mukuru kuteya zvinhu zvinotonhora zvinogadzirwa pakati pemajekiseni maviri pamagumo emuromo kudzivirira kuvharika kweanomhanya kana gedhi.Kamwe iyo inotonhora inosanganiswa mugomba, kushushikana kwemukati kungangoitika muchigadzirwa chakagadzirwa.Iyo dhayamita yegomba rinotonhora reslug rinenge 8-10mm uye kudzika i6mm.Kuti zvive nyore kudhirowa, pasi inowanzotakurwa netsvimbo yekudzikisa.Iyo yepamusoro yetsvimbo yekubvisa inofanira kugadzirwa mune zigzag hook chimiro kana kugadzika neyakagadziriswa groove, kuitira kuti sprue ibudiswe kunze zvakanaka panguva yekudonha.
Shunt:
Ndiyo chiteshi chinobatanidza chiteshi chikuru uye yega yega mune yakawanda-slot mold.Kuti iite kuti kunyunguduka kuzadze mhango pamwero wakafanana, kurongeka kwevamhanyi pane mold kunofanira kunge kwakaenzana uye kwakaenzana.Chimiro uye hukuru hwemuchinjikwa-chikamu chemumhanyi zvine simba pakuyerera kwepurasitiki yakanyunguduka, chigadzirwa chekugadzira uye kuoma kwekugadzira mold.Kana kuyerera kwehuwandu hwehuwandu hwezvinhu hunoshandiswa, iyo inoyerera nzira yekupikisa ine denderedzwa muchinjikwa-chikamu ndiyo diki.Nekudaro, nekuti iyo chaiyo nzvimbo ye cylindrical mumhanyi idiki, haina kunaka kutonhora kweanomhanya asina basa, uye mumhanyi anofanira kuvhurwa pamahafu maviri ekuumbwa, ayo anoshanda zvakanyanya uye akaoma kuenzanisa.Nokudaro, trapezoidal kana semicircular cross-section runners inowanzoshandiswa, uye inovhurwa pahafu ye mold ine tsvimbo yekubvisa.Iyo yekumhanya yepasi inofanirwa kukwenenzverwa kuti ideredze kuyerera kuramba uye kupa nekukurumidza kuzadza kumhanya.Kukura kwemumhanyi kunoenderana nerudzi rwepurasitiki, ukuru uye ukobvu hwechigadzirwa.
Kune akawanda thermoplastics, kuyambuka-chikamu upamhi hwevamhanyi haapfuuri 8mm, iyo yakawedzera-yakakura inogona kusvika 10-12mm, uye yakawedzera-diki 2-3mm.Pamusoro pekusangana nezvinodiwa, nzvimbo yepamuchinjikwa inofanira kuderedzwa zvakanyanya sezvinobvira kuwedzera tsvina yemumhanyi uye kuwedzera nguva yekutonhora.
