Hot Runer Runer Ruzivo mu jekiseni Molding Machine

Kugovana ruzivo rwejekiseni mold hot runner tekinoroji mukati jekiseni kuumba muchina

Kupisa mumhanyi gating system inogona kunzwisiswa sekuwedzera kwemajekiseni ekuumba michina. Basa reiyo inopisa mumhanyi system kuendesa iyo thermoplastic kunyunguduka kune padhuze nekuumbwa kufa kana zvakananga mufa adiabatically..

Mumhanyi anopisa anogona kupisa akazvimirira, asi thermally insulated mujekiseni mold, kuitira kuti inogona kubhadhara yega yekurasikirwa kwekupisa kunokonzerwa nekusangana ne “kutonhora” mold.

Moto mumhanyi molds akashandiswa zvinobudirira kugadzira akasiyana epurasitiki zvinhu, uye zvinenge zvese zvepurasitiki zvinhu zvinogona kugadziriswa neanotonhora mumhanyi molds zvinogona kugadzirwa neanopisa mumhanyi molds..

Chikamu chidiki pane zvishoma pane 0.1 magiramu, uye chikamu chikuru chinopfuura 30 makirogiramu. Hot mumhanyi molds anoshandiswa zvakanyanya muminda yemagetsi, motokari, kurapwa, zvinodiwa zuva nezuva, matoyi, kurongedza, kuvaka, uye midziyo yemuhofisi.

A kubudirira inopisa mumhanyi mold application project inoda akawanda ma link kuti avimbiswe.

Pakati pezvinonyanya kukosha zvinhu zviviri zvehunyanzvi: imwe inodzora kupisa kwepurasitiki;
Chechipiri ndechekudzora kuyerera kwepurasitiki.

Yakajairika hot runner system ine zvikamu zvinotevera: 1) Hot mumhanyi ndiro (MANIFOLD); 2) Nozzle (NOZZLE); 3) Temperature controller; 4) Zvikamu zvebetsero.

Zvakanakira zve inopisa mumhanyi molds:
1) Kupfupisa kuumbwa kwezvikamu;
2) Chengetedza zvinhu zvepurasitiki;
3) Deredza marara uye uvandudze chigadzirwa chemhando;
4) Bvisa maitiro anotevera, iyo inobatsira kugadzira otomatiki;
5) Wedzera kushandiswa kwejekiseni molding tekinoroji.

Panguva imwe, kunewo zvikanganiso zvakadai sekukwira kwemari yekuumbwa, yakakwirira yekugadzira maitiro emidziyo zvinodiwa, uye kushanda kwakaoma uye kugadzirisa.

Mhando uye mashandisirwo eanopisa mumhanyi masisitimu

Paunenge uchishandisa kupisa mumhanyi tekinoroji, sarudzo yakarurama yemhando yegedhi inokosha zvikuru. Mhando yegedhi inogadzirisa zvakananga kusarudzwa kwezvinopisa mumhanyi system zvikamu uye kugadzirwa uye kushandiswa kwe molds.

Naizvozvo, maererano nemhando dzakasiyana dzemagedhi, iyo inopisa mumhanyi system inogona kukamurwa kuva marudzi matatu: hot tip inopisa mumhanyi system, sprue inopisa mumhanyi system, uye vharafu inopisa mumhanyi system. Imwe neimwe mhando yeanopisa mumhanyi system ine yayo yakakosha application. Zvimiro uye chiyero chekushandisa.

Zvinhu zvakawanda zvinoda kutariswa pakusarudza mhando dzemasuwo uye inopisa mumhanyi masisitimu, iyo inonyanya kukosha iyo ndeyemhando yeplastiki matrix uye zvinowedzera, uremu uye ukuru hwezvikamu, zvinodiwa zvehutano zvezvikamu, hupenyu hwematurusi uye zvinodiwa zvekugadzira zvezvikamu.

1 Hot tip inopisa mumhanyi system (HOT TIP)
Nheyo yayo yekushanda ndeyekubatanidza iyo HOT TIP kumberi kumagumo emuromo neinotonhorera sisitimu kunyatsogadzirisa uye kudzora tembiricha yekuumbwa kwepurasitiki pagedhi.. Naizvozvo, iyo yekugadzira zvinhu uye chimiro dhizaini yemuromo inoisa HOT TIP yakakosha.HOT TIP inopisa mumhanyi system inogona kushandiswa kugadzira yakawanda crystalline uye amorphous mapurasitiki akadai sePP., Kuti udzivise kusvibiswa kwezvinhu zvakasvibirira uye kuvapo kwezvinhu zvekare kana kusvibiswa mumashure escrew uye accessories., PS, LCP, PA, PET, PBT, PEEK, POM, PEI, PMMA, ABSPVC, PC , PSU, TPU, nezvimwewo. Kazhinji kutaura, hot tip magedhi anonyanya kushandiswa kugadzirisa zvikamu zviduku uye zvepakati, kunyanya pakugadzirisa zvikamu zviduku.

Iyo dhayamita yechikamu chegedhi kazhinji iri pakati pe 0.5mm-2.0mm. The kutsunga yehupamhi hwechikamu chegedhi chinonyanya kutsanangurwa nehuremu uye madziro emadziro echikamu, uye zvechokwadi zvinhu uye chikamu chemhando zvinodiwa zvinofanirwa kutariswa.

Kana gedhi rine diki diki-sectional dhayamita rinoshandiswa, gedhi richavharwa nekukurumidza mushure mekunge jekiseni rekuzadza danho rapera, zvikwangwani zvegedhi pachikamu zvichava zviduku, uye pamusoro pechikamu chichava nechitarisiko chakanaka uye chakanaka.

Kana dhayamita yegedhi iri diki, iyo shear rate ichave yakanyanya kukwirira kana plastiki ichiyerera nepagedhi, iyo ichakuvadza zvakanyanya chimiro chemolecular cheni yepurasitiki yakanyunguduka kana izvo zvinowedzera mupurasitiki, zvichikonzera zvigadzirwa zvisina kukodzera izvo zvisingakwanisi kuzadzisa zvinodiwa zvekushandisa.

Mukusarudza kwekukura kwegedhi, chinowanzoitwa ndechekutanga kuona saizi yegedhi zvinoenderana neukobvu hwemadziro pagedhi rechikamu: gedhi dhayamita = (0.75-1.0) ukobvu hworusvingo pasuo rorutivi. Iko kukosha kudiki kunoshandiswa kugadzira mapurasitiki ari nyore-kuyerera, uye kukosha kukuru kunoshandiswa pakugadzirisa mapurasitiki akaoma-anoyerera kana mapurasitiki anonzwa kugera.
Kazhinji gedhi rinopisa rinopisa rinovhurwa zvakananga pane chikamu, asi inogonawo kuvhurwa pane inotonhora inomhanya uye ipapo gedhi rinotonhora rinovhurwa pane chikamu. Iyi ndiyo mold system inosanganisa inopisa mumhanyi uye inotonhora mumhanyi. Paunenge uchishandisa magedhi ekupisa anopisa kugadzira zvikamu zvepurasitiki, pachagara paine mamwe kana mashoma emagedhi mamaki pazvikamu.

Nguva zhinji mamaki egedhi achave akakwirira kupfuura pamusoro pechikamu, kukanganisa kunaka kwechikamu kana kukanganisa gungano nemamwe mativi. Naizvozvo, pakusarudza nzvimbo yegedhi, edza kuisa gedhi muchikamu chakavanzwa chakavanzika pane chikamu.

2SPRUE GATING system (SPRUE GATING)
Mune sprue inopisa mumhanyi system, ipurasitiki inopinda mumhango yeforoma kuburikidza nemumhanyi wakashama (Vhura PIPE). Iyo yepurasitiki inoyerera yekumanikidza kurasikirwa pagedhi idiki. Iyo sprue inopisa mumhanyi system inonyanya kukodzera kuumbwa kwejekiseni yezvikamu zvine saizi yepakati uye huremu.

Chakanakira kushandisa sprue inopisa mumhanyi system ndechekuti purasitiki inopinda yakaderera shear rate kana ichiyerera nepagedhi uye ichizadza mold., iyo yakasara kushushikana mushure mekunge chikamu chaumbwa idiki, dhigirii ye deformation idiki, uye simba remagetsi rechikamu riri nani. Kuenzaniswa nemasuo anopisa ematipi, magedhi esprue akakura muhukuru, saka mamaki emagedhi anogonawo kunge akakura.

Naizvozvo, mumamiriro ezvinhu akajairika, molds ane zvinodiwa zvakasimba kune aesthetics yegedhi inowanzoshandisa plastiki jekiseni molding; uye zvikamu zvemukati zvemukati zvisingade aesthetics yakakwira yegedhi inogona kugadzirwa nesprue-mhando inopisa mumhanyi system..

Vanhu vanowanzo shandisa sprue sprue pamwe chete neanotonhora mumhanyi, ndizvo, iyo sprue nozzle inoshandiswa semumhanyi mukuru, uye sprue sprue yakazarurwa pane inotonhora inomhanya. Muchikumbiro ichi, gedhi resprue rinogona kuvhurwa rakakura kuti riite kuyerera kwepurasitiki, nekuti hapana ane hanya nehukuru hwemagedhi mamaki pane inotonhora inomhanya.

Zvakafanana nekushandiswa kwehot-tip inopisa mumhanyi masisitimu, the control of the plastic temperature and mold temperature at the gate is extremely important. A separate cooling circuit needs to be set up around the gate. Because the size of the sprue gate is relatively large, if the temperature at the gate is not well controlled, it is more likely that the gate cannot seal the plastic flowing after the mold is opened.

The nozzle insert of the sprue hot runner system also has a variety of sizes and shapes and changes in manufacturing materials, which must be considered in combination with the type of plastic to be processed (such as crystalline plastic or amorphous plastic) and the cooling of the gate.

Kana uine chero mibvunzo pa jekiseni kuumbwa ,plz sunungukai kubvunza FLYSE timu,tichakupa yakanakisa sevhisi!
