Matambudziko nemhinduro dzakakonzerwa nemadziro akaonda emota bumper

Iyo bumper yemota ndechimwe chezvishongedzo zvakakura pamotokari, ine mabasa makuru matatu: kuchengetedza, kushanda uye kushongedzwa.
Pane nzira nhatu huru dzemota bumper lightweight: material lightweight, structure optimization dhizaini uye kugadzira maitiro ekugadzira.Material lightweight kazhinji inoreva kutsiva izvo zvekutanga pasi pemamwe mamiriro, senge epurasitiki yesimbi;bumper lightweight chimiro optimization dhizaini inonyanya ine yakatetepa-madziro tekinoroji;Iyo nyowani yekugadzira maitiro ine micro-foam zvinhu uye gasi rinobatsira kuumba uye humwe hunyanzvi hunyanzvi.
Plastiki bumper zvinhu zvekusarudza mapurasitiki nekuda kwechiedza chemhando, kuita kwakanaka kwekuita, kugadzira kuri nyore, kusakara, kuramba, kusununguka kwedhizaini uye humwe hunhu, hunoshandiswa zvakanyanya muindasitiri yemotokari, uye chikamu chekuwedzera mune zvemotokari zvinhu.Huwandu hwepurasitiki inoshandiswa pamotokari yave imwe yenzira yekuyera budiriro yeindasitiri yemotokari yenyika.Parizvino, nyika dzakabudirira kugadzira mota yekushandiswa kwepurasitiki yasvika 200kg, inoverengera nezve 20% yemhando yemotokari.
Plastiki muindasitiri yemotokari yekuChina yave kunonoka kushandiswa, huwandu hwepurasitiki mumotokari dzehupfumi hungori 50 ~ 60kg, mota dzevakuru dzine 60 ~ 80kg, dzimwe mota dzinogona kusvika 100kg, China mukugadzirwa kwemarori epakati nepakati, mota imwe neimwe ine dzinenge. 50kg yepurasitiki.Motokari imwe neimwe inoshandisa purasitiki kwe5 kusvika ku10 muzana yehuremu hwemotokari.
Zvishandiso zvebumper zvinowanzove nezvinotevera zvinodiwa: yakanaka kukanganisa kuramba, kunaka kwemamiriro ekunze.Yakanaka pendi yekubatanidza kugona, yakanaka fluidity, yakanaka kugadzirisa kuita, mutengo wakaderera.Saizvozvo, PP kirasi zvinhu pasina mubvunzo iri nani inodhura-inoshanda sarudzo.PP zvinhu imhando yepurasitiki yakajairika ine kuita kwakanaka, asi PP pachayo ine kushomeka kwekushisa kwekuita uye kupikisa kuramba, kusapfeka kuramba, kuchembera kuri nyore uye kusasimba kwakadzikama, saka yakagadziridzwa PP inowanzo shandiswa sechigadzirwa chemota bumper.Parizvino, iyo polypropylene mota bumper specialized zvinhu zvinowanzo PP sechinhu chikuru, uye wedzera chimwe chikamu cherabha kana elastomer, inorganic filler, mavara amai particles, additives uye zvimwe zvinhu mushure mekusanganiswa nekugadziriswa.

Zviri nyore kukonzeresa warping deformation, inova mugumisiro wekushushikana kwemukati.Mabhampa akatetepa anokonzera kushushikana kwemukati mumatanho akasiyana-siyana ekuumba jekiseni.
Kazhinji, inonyanya kusanganisira kutaridzika kushushikana, kushushikana kwekushisa uye mold kuburitsa kushushikana.Orientation stress ndiko kukwezva kwemukati kunokonzerwa nefibers, macromolecular chains kana cheni segments in the melt iri kutariswa mune imwe nzira uye inokonzerwa nekusakwana kuzorora.Iyo yekutarisa ine hukama nehupamhi hwechigadzirwa, kunyunguduka tembiricha, mold tembiricha, jekiseni kudzvanywa, uye kudzvanywa kwekuchengetedza nguva.Iyo yakakwirira iyo gobvu, iyo yakaderera yakatarisa;iyo yakakwirira tembiricha yekunyunguduka, yakadzikira yakatarisa, yakaderera yakatarisa;iyo yakakwirira yekumanikidza kwejekiseni, iyo yakakwirira yekutarisa;iyo yakareba iyo nguva yekuchengetedza dzvinyiriro, iyo huru yekutarisa.
Thermal stress inokonzerwa nekupisa kwepamusoro kwekushisa kwe mold uye kuderera kwekushisa kwe mold, uye kukurumidza kutonhora kwekunyunguduka munzvimbo iri pedyo nehombe.Kushungurudzika kwekusunungura kunonyanya kukonzerwa nekusakwana kwesimba uye kuoma kwe mold, iyo elastic deformation pasi pechiito chekumanikidza jekiseni uye kubuda kwepamusoro, uye kurongeka kusinganzwisisike kwekugovera kwechigadzirwa hakuna kuenzana.Iyo bumper yakaonda madziro inogona zvakare kuoma.Nemhaka yokuti geji yemadziro emadziro iduku uye ine shrinkage duku, chigadzirwa chacho chakanyatsoomerera kune mold;iyo yekumanikidza kubata nguva yekudzora kwakaoma, uye iyo yakaonda madziro ukobvu nekusimbisa zvinokuvadzwa nyore.Kuvhura kwakajairika kwe mold kunoda sirinji kuti ipe simba rakakwana rekuvhura mold, iyo inofanirwa kukwanisa kukunda kupokana kwekuvhura mold.

Pane zvipingamupinyi zvakati kuti zvinokurirwa mukuvhurwa kwe mold

Chokutanga pane zvose, zvakakosha kukunda simba rekuzarura rakananga.Kana mold ikavhurwa, purasitiki ichange iine imwe adhesion force inoenderana neinovhura nzira, iyo inokonzerwa nekutonhodzwa kwezvikamu zvepurasitiki kana kutonhora kwe mold kusingakwane, uye kuwedzera elastic kwemhando yegomba haina kudzoserwa zvizere.Saizi yesimba rekunamatira iri rine hukama nehunhu hwepurasitiki, kunaka kwepamusoro kwe mold, kutsetseka kwefodya, nezvimwe. Pamusoro pezvo, zvinodikanwa kukurira kusarongeka kwekuvhura mold, ndiko kuti, divi rine mota. core extraction process.Izvo zvinodiwawo kukurira kupesana kwekupokana kunokonzerwa nekufamba kweiyo mold inofamba template uye template yebasa.Zvadaro zvakakosha kukurira kupindira kwekumanikidzwa kwegomba, apo kudzvinyirirwa kwegomba kungave kusina kuenzana nemhepo yemhepo, uye kudzvinyirirwa mumhango hakusi kuenzana nekunze kwekunze.
Kuti ugadzirise matambudziko maviri ari pamusoro apa, dhizaini ye mold inoda kuvandudzwa nemazvo.Sarudza iyo yakakodzera mold zvinhu kuti uvandudze mold yekupisa simba uye kupfeka kuramba.Inonzwisisika mold dhizaini dhizaini uye kugadzira, zvakakodzera kuwedzera ukobvu hwepush plate uye yepakati pad ndiro, kunatsiridza kuoma kwe mold, kuderedza elastic deformation ye mold.Kuvandudza kugadzira uye kurongeka kwechokwadi kweiyo musimboti kudhirowa michina uye yekufambisa sisitimu, kuderedza kushata kwepamusoro kwemhando yemhando, musimboti uye convex module zvikamu, uye kuderedza mold kuburitsa simba.Iine dhizaini yepamusoro uye kuenderana chaiko kunodiwa, mudziyo wekubatanidza unowanzo kupihwa kudzivirira kutama kweiyo difa core uye mhango yekufa.Iyo yekudira sisitimu inofanirwa kugadzirwa nemazvo, uye dhizaini yekuyerera inofanirwa kushandisa zvakanyanya zvikamu zvepurasitiki kubva munzvimbo dzakakora kuenda kunzvimbo dzakatetepa panguva yejekiseni.Pachadawo kunge paine maepoust ports akakwana.Panyaya yemaitiro ejekiseni, kushushikana kwemukati kwezvikamu zvepurasitiki kunofanirwa kudzikiswa, uye kumhanya kwejekiseni uye kumhanya kwekutonhora kunofanirwa kudzikiswa.Kuwedzera tembiricha yekunyunguduka uye tembiricha yekuumbwa zvinodikanwa kuti iregedzerwe.Huangyan Leiao Molding Co., Ltd. iri muHuangyan District mold city, Taizhou, mudunhu reTaizhou, rinova "Musha weChinese mold".Iyo kambani inonyanya kuita mukugadzira jekiseni mold, ine makore mazhinji ehunyanzvi hwekugadzira mold, kunyanya kugadzira nekugadzirisa bhodhoro embryo mold, PET commodity mold, bhodhoro cap mold, mukati memota uye kunze kwekushongedza mold… … mold system ine yayo yakasarudzika dhizaini uye kugadzirisa tekinoroji, zvichibva pane iyo pfungwa ye "Kutendeseka manejimendi", ine vatengi vekumba nevekunze kuti vagadzire hukama hwenguva refu hwekubatana, ndinotenda kuti Leiao achave akakodzera kuvimba newe mumubatanidzwa. enterprise.
