kub khiav kev paub hauv kev txhaj tshuaj molding tshuab

Kev paub txog kev txhaj tshuaj pwm kub khiav tshuab hauv txhaj tshuaj molding tshuab

Kub khiav qhov rooj qhov system tuaj yeem nkag siab tias yog qhov txuas ntxiv ntawm kev txhaj tshuaj molding tshuab. Kev ua haujlwm ntawm lub tshuab kub khiav yog xa cov thermoplastic yaj mus rau thaj tsam ntawm molding tuag los yog ncaj qha mus rau hauv tuag adiabatically..

Cov kub khiav tuaj yeem ua kom sov ntawm nws tus kheej, tab sis thermally insulated hauv kev txhaj tshuaj pwm, yog li ntawd nws tuaj yeem them nyiaj rau tus kheej rau qhov kub poob los ntawm kev sib cuag nrog cov “txias” pwm.

Kub khiav pwm tau ua tiav siv los ua ntau yam ntaub ntawv yas, thiab yuav luag txhua cov ntaub ntawv yas uas tuaj yeem ua tiav nrog cov pwm txias khiav tuaj yeem ua tiav nrog cov pwm kub khiav.

Qhov tsawg tshaj plaws yog tsawg dua 0.1 grams, thiab qhov loj tshaj plaws yog ntau tshaj 30 kilograms. Kub khiav pwm yog siv dav hauv cov khoom siv hluav taws xob, tsheb, kev kho mob, cov khoom siv niaj hnub, khoom ua si, ntim, kev tsim kho, thiab cov khoom siv hauv chaw ua haujlwm.

Kev vam meej kub khiav pwm daim ntawv thov qhov project xav tau ntau qhov txuas kom tau lees paub.

Ntawm qhov tseem ceeb tshaj plaws yog ob yam txuj ci: ib qho yog kev tswj cov yas kub;
Qhov thib ob yog kev tswj cov yas ntws.

Ib tug raug kub khiav system muaj cov nram qab no: 1) Kub khiav phaj (MANIFOLD); 2) Nozzle (NOZZLE); 3) Kub tswj; 4) Pab qhov chaw.

Qhov zoo ntawm kub khiav pwm:
1) Shorten lub voj voog molding ntawm qhov chaw;
2) Txuag cov khoom siv yas;
3) Txo cov khoom pov tseg thiab txhim kho cov khoom zoo;
4) Tshem tawm cov txheej txheem tom ntej, uas yog conducive rau ntau lawm automation;
5) Nthuav daim ntawv thov ntawm kev txhaj tshuaj molding tshuab.

Tib lub sijhawm, kuj tseem muaj qhov tsis zoo xws li nce pwm cov nqi, high manufacturing txheej txheem khoom yuav tsum, thiab kev ua haujlwm nyuaj thiab kev saib xyuas.

Hom thiab kev siv ntawm kub khiav tshuab

Thaum thov kub khiav tshuab, qhov kev xaiv raug ntawm hom rooj vag yog qhov tseem ceeb heev. Lub rooj vag hom ncaj qha txiav txim siab xaiv cov txheej txheem kub khiav thiab kev tsim thiab siv cov pwm.

Yog li ntawd, raws li hom rooj vag sib txawv, qhov kub khiav system tuaj yeem muab faib ua peb hom: kub taub hau kub khiav system, sprue kub khiav system, thiab valve kub khiav system. Txhua hom kub khiav system muaj nws daim ntawv thov tseem ceeb. Nta thiab Scope ntawm daim ntawv thov.

Ntau yam yuav tsum tau xav txog thaum xaiv cov hom rooj vag thiab kub khiav tshuab, qhov tseem ceeb tshaj plaws uas yog hom yas matrix thiab additives, qhov hnyav thiab qhov loj ntawm qhov chaw, qhov kev xav tau zoo ntawm cov khoom, lub cuab yeej lub neej thiab cov kev xav tau ntawm cov khoom.

1 Kub taub hau kub khiav system (KUB TIM)
Nws lub hauv paus ntsiab lus ua haujlwm yog los ua ke HOT TIP nyob rau pem hauv ntej kawg ntawm lub nozzle nrog lub tshuab cua txias kom raug kho thiab tswj cov yas molding ua kub ntawm lub rooj vag.. Yog li ntawd, Cov khoom tsim thiab cov qauv tsim ntawm lub nozzle ntxig HOT TIP yog ib qho tseem ceeb heev.HOT TIP kub khiav system siv tau los ua cov txheej txheem feem ntau crystalline thiab amorphous yas xws li PP., ON, PS, LCP, PA, PET, PBT, PEB, POM, PEI, PMMA, ABSPVC, PC , PSU, TPU, lwm yam. Feem ntau hais lus, cov qhov rooj kub taub hau feem ntau yog siv rau kev ua cov khoom me me thiab nruab nrab, tshwj xeeb tshaj yog rau kev ua cov khoom me me.

Txoj kab uas hla ntawm lub rooj vag yog feem ntau ntawm 0.5mm-2.0mm. Cov kev txiav txim siab ntawm txoj kab uas hla ntawm lub rooj vag seem yog tsuas yog txiav txim los ntawm qhov hnyav thiab phab ntsa thickness ntawm ib feem, thiab tau kawg cov khoom siv thiab ib feem zoo yuav tsum tau xav txog.

Yog siv ib lub rooj vag nrog ib txoj kab uas hla me me, lub rooj vag yuav raug kaw sai sai tom qab kev txhaj tshuaj filling theem tiav, lub rooj vag cim ntawm ib feem yuav me me, thiab qhov saum npoo ntawm ib feem yuav zoo li zoo thiab zoo.

Yog lub rooj vag txoj kab uas hla me dhau, tus nqi shear yuav siab dhau thaum cov yas ntws los ntawm lub rooj vag, uas yuav ua rau puas tsuaj rau lub molecular saw qauv ntawm cov yas yaj los yog cov additives hauv cov yas, ua rau cov khoom tsis tsim nyog uas tsis tuaj yeem ua tau raws li qhov yuav tsum tau siv.

Hauv kev xaiv ntawm lub rooj vag loj, qhov kev coj ua niaj hnub yog pib txiav txim siab lub rooj vag loj raws li phab ntsa thickness ntawm lub rooj vag: gate diam = (0.75-1.0) phab ntsa thickness ntawm qhov rooj qhov rooj. Tus nqi me dua yog siv los ua cov khoom siv yooj yim-flow, thiab tus nqi loj dua yog siv rau kev ua cov khoom siv tawv tawv los yog cov yas uas muaj kev cuam tshuam rau shear.
Feem ntau lub qhov rooj kub taub hau yog qhib ncaj qha rau ntawm ib feem, tab sis nws tseem tuaj yeem qhib rau ntawm tus neeg khiav dej num txias thiab tom qab ntawd lub rooj vag txias tau qhib rau ntawm ib feem. Qhov no yog ib qho pwm uas sib xyaw ua ke kub khiav thiab txias khiav. Thaum siv cov qhov rooj kub taub hau los ua cov khoom yas, yeej yuav muaj ntau los yog tsawg lub rooj vag cim rau ntawm qhov chaw.

Ntau zaus lub rooj vag cov cim yuav siab dua qhov chaw ntawm qhov chaw, cuam ​​tshuam rau kev zoo nkauj ntawm ib feem lossis cuam tshuam rau kev sib dhos nrog lwm qhov chaw. Yog li ntawd, thaum xaiv lub rooj vag qhov chaw, sim muab lub rooj vag nyob rau hauv lub recessed concealed ib feem ntawm ib feem.

2SPRUE GATING system (SPRUE GATING)
In the sprue hot runner system, the plastic enters the mold cavity through an open runner (OPEN PIPE). The plastic flow pressure loss at the gate is small. The sprue hot runner system is more suitable for injection molding of parts with medium size and weight.

The advantage of using the sprue hot runner system is that the plastic undergoes a low shear rate when it flows through the gate and fills the mold, the residual stress after the part is formed is small, the degree of deformation is small, and the mechanical strength of the part is better. Compared with hot tip gates, sprue gates are larger in size, so gate marks may also be larger.

Yog li ntawd, under normal circumstances, molds with strict requirements for the aesthetics of the gate often use plastic injection molding; and internal structural parts that do not require high aesthetics for the gate can be manufactured by a sprue-type hot runner system.

People often use the sprue sprue in combination with the cold runner, yog, the sprue nozzle is used as the main runner, and the sprue sprue is opened on the cold runner. In this application, the sprue gate can be opened larger to facilitate the flow of the plastic, because no one cares about the size of the gate marks on the cold runner.

Similar to the application of hot-tip hot runner systems, 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.
