Yakarasika foam casting, inozivikanwawo seyakasimba mold casting, ndeyekubatanidza nekubatanidza foam modhi dzehukuru hwakafanana nekukandwa mumasumbu emhando.Mushure mekukwesha nependi refractory uye kuomeswa, vanovigwa mujecha rakaoma requartz kuti riite vibration modeling, uye rinodururwa pasi pekumanikidzwa kwakashata kuita sumbu remuenzaniso.Model gasification, simbi yemvura inogara pachinzvimbo cheiyo modhi, yakaomeswa uye yakatonhodzwa kuumba nzira nyowani yekukanda.Iyo yese process inoyerera seinotevera:

Kutanga, kusarudzwa kwefoam bead:

Anowedzera polystyrene resin beads (EPS) anowanzo kushandiswa kukanda asiri-ferrous simbi, grey iron uye general simbi yekukanda.

2. Kugadzira modhi: Pane mamiriro maviri:

1. Yakagadzirwa nefuro bead: pre-foaming - kurapa - furo kuumba - kutonhora uye ejection

①Pre-foaming: Mabheji eEPS asati awedzerwa kune mold, anofanirwa kunge afanoputirwa kuti awedzere mabhero kune imwe saizi.Iyo pre-foaming process inosarudza density, dimensional kugadzikana uye kurongeka kweiyo modhi uye ndeimwe yeakakosha link.Pane nzira nhatu dzakakodzera dzebead prefoaming: mvura inopisa prefoaming, steam prefoaming uye vacuum prefoaming.Vacuum pre-foamed beads ine furo yakanyanya mwero, mabhero akaoma, uye anoshandiswa zvakanyanya.

②Kuchembera: Mabhero eEPS asati aita furo anoiswa mu silo yakaoma uye inofefetera kwenguva yakati.Kuti uenzanise kudzvinyirirwa kwekunze mumasero ebhedhi, ita kuti mabheji ave nekugadzikana uye kukwanisa kuwedzerazve, uye kubvisa mvura pamusoro pemabheji.Nguva yekukwegura ndeye 8 kusvika ku48 maawa.

③ Foam kuumba: Zadza mabhero eEPS akafanofuro uye akapora mugomba resimbi mold, uye pisa mabhero kuti awedzere zvakare, zadza maburi pakati pemabhero, uye sanganisa mabhesi kune mumwe nemumwe kuti agadzire nzvimbo yakatsetseka, iyo modhi. .Inofanira kutonhodzwa pamberi pekuumbwa kusunungurwa, kuitira kuti modhi yacho itonhodzwe kusvika pazasi kunyorova tembiricha, uye mold inogona kusunungurwa mushure mekunge modhi yaoma uye yakaumbwa.Mushure mekunge mold yaburitswa, panofanirwa kuve nenguva yekuti iyo modhi iome uye yakadzikama.

2. Yakagadzirwa nefuro yepurasitiki pepa: foam plastiki sheet - resistance wire cutting - bonding - model.Kune akareruka mamodheru, iyo yekupokana waya yekucheka mudziyo inogona kushandiswa kucheka furo pepa repurasitiki mune inodiwa modhi.Pamhando dzakaoma, tanga washandisa chigadziro chekucheka kwewaya kuti ugovane modhi muzvikamu zvakati wandei, wozoinamatira kuti iite modhi yese.

3. Mienzaniso inosanganiswa kuva zvikwata: iyo inozvigadzirisa (kana kutenga) foam model uye inodurura riser model inosanganiswa uye inobatanidzwa pamwe chete kuti iite mutsara wemuenzaniso.Uku kusanganiswa dzimwe nguva kunoitwa pamberi pekuputira, dzimwe nguva mukugadzirira kwekuputira.Inoitwa panguva yemashure-embedding bhokisi modelling.Icho chinhu chakakosha muitiro mukurasika furo (yakasimba) kukanda.Parizvino anoshandiswa bonding zvinhu: rabha latex, resin solvent uye inopisa inonyungudutsa adhesive uye tepi bepa.

4. Kupfekedzwa kwemuenzaniso: Pamusoro peiyo yakasimba yekukanda foam modhi inofanirwa kuve yakaputirwa nehumwe hukobvu hwepende kuti igadzire mukati meganda rekukanda mold.Kune yakakosha pendi yekukanda furo yakarasika, wedzera mvura uye simbisa musanganisi wependi kuti uwane viscosity yakakodzera.Iyo pendi yakamutswa inoiswa mumudziyo, uye boka remuenzaniso rakaputirwa nemaitiro ekunyura, kukwesha, kugezesa nekupfapfaidza.Kazhinji, shandisa kaviri kuita ukobvu hwekuputira 0.5 ~ 2mm.Inosarudzwa maererano nemhando yekukanda alloy, chimiro chechimiro uye saizi.Iyo yekuputira yakaomeswa pa40 ~ 50 ℃.

5. Vibration modeling: iyo nzira inosanganisira matanho anotevera: kugadzirira mubhedha wejecha - kuisa EPS muenzaniso - kuzadza jecha - kuvhara uye kuumba.

① Kugadzirira mubhedha wejecha: Isa bhokisi rejecha rine kamuri yekudhonza mhepo patafura inozunguza woisunga zvakasimba.

②Isa modhi: Mushure mekudedera, isa iyo EPS modhi boka pairi zvinoenderana nemaitiro ekuita, uye gadzirisa nejecha.

③ Kuzadza jecha: wedzera jecha rakaoma (nzira dzinoverengeka dzekuwedzera jecha), uye panguva imwechete shandisa vibration (X, Y, Z mativi matatu), nguva yacho inowanzoita 30 ~ 60 masekondi, kuitira kuti jecha rekuumbwa rizadzwe nezvikamu zvese. yemuenzaniso, uye jecha rinozadzwa nejecha.Bulk density inowedzera.

④Chisimbiso uye chimiro: Pamusoro pebhokisi rejecha rakanamwa nefirimu repurasitiki, mukati mebhokisi rejecha rinopomberwa mune imwe vacuum ine vacuum pombi, uye tsanga dzejecha "dzinosungirirwa" pamwe chete nemusiyano pakati pekumanikidza kwemhepo uye. kudzvinyirirwa mu mold, kuitira kuchengetedza mold kubva pakudonha panguva yekudurura., inonzi "negative pressure setting, inonyanya kushandiswa.

6. Kudururira kutsiva: Iyo modhi inowanzopfaviswa panenge 80 °C, uye yakaora pa420 ~ 480 °C.Zvigadzirwa zvekuora zvine zvikamu zvitatu: gasi, mvura uye yakasimba.Kupisa kwekupisa kwekupisa kwakasiyana, uye zviri mukati mezvitatu zvakasiyana.Kana iyo yakasimba mold inodururwa, pasi pekupisa kwesimbi yemvura, iyo EPS modhi inopinda pyrolysis uye gasification, uye yakawanda gasi inogadzirwa, iyo inoramba ichiburitswa kuburikidza nejecha rekuputira uye ichiburitswa kunze, ichigadzira imwe mweya. kumanikidzwa mukuumbwa, modhi uye gomba resimbi.Simbi inoramba ichigara pachinzvimbo cheiyo EPS modhi uye inofambira mberi, uye nzira yekutsiva yesimbi yemvura uye EPS modhi inoitika.Mhedzisiro yekutama ndiko kuumbwa kwekukanda.

7. Kutonhodza uye kuchenesa: Mushure mekutonhodza, ndiyo iri nyore kudonhedza jecha mukukanda kwakasimba.Zvinokwanisika kurerekera bhokisi rejecha kuti usimudze kukanda kunze kwebhokisi rejecha kana kusimudza zvakananga kukanda kunze kwebhokisi rejecha, uye jecha rekukanda uye rakaoma zvakaparadzaniswa zvakasikwa.Jecha rakaparadzaniswa rakaoma rinorapwa uye rinoshandiswa zvakare.
