Vim li cas cov txheej txheem txhaj tshuaj molding khoom burr thiab yuav daws nws li cas?

Feem ntau ntawm cov burrs ntawm kev txhaj tshuaj molding cov khoom tshwm sim ntawm qhov chaw sib cais, piv txwv li, nruab nrab ntawm cov pwm txav mus los thiab cov pwm zoo li qub, qhov zawv zawg ntawm cov slider, qhov sib txawv ntawm qhov ntxig, qhov ntawm lub qhov rooj sab saum toj, thiab lwm yam. cov khoom molten ntws mus rau hauv qhov chaw, tsim tshaj ya burrs ntawm qhov chaw.

Ua ntej, dab tsi yog qhov txhaj tshuaj molding burr?

Muaj ntau lub npe rau burrs, xws li ya ya, ntug ntug dej, cov khoom ntws, thiab lwm yam. Cov tswv sib txawv muaj cov npe sib txawv, tab sis lawv txhua tus txhais tau tib yam.

Qhov thib ob, qhov ua rau ntawm burrs

Qhov tshwm sim ntawm burrs nyob rau hauv kev txhaj tshuaj molding txheej txheem yog vim lub overflow ntawm molten txhaj resin los ntawm cov pwm parting nto, tshwj xeeb tshaj yog yog hais tias tus burr nrees adheres rau pwm parting nto, nws yuav ncaj qha puas pwm parting nto, ib zaug cov pwm puas lawm. , thiab tom qab ntawd cov txheej txheem txhaj tshuaj molding, nws yuav tsim qhov tshwm sim ntawm burrs, thiab tseem yuav ua rau txo qis hauv lub neej ntawm cov pwm, burrs yog tsim los ntawm cov laj thawj hauv qab no.

1. tsis txaus clamping quab yuam

Yog hais tias lub clamping quab yuam me me piv rau qhov projected cheeb tsam ntawm lub molded ib feem, lub txhaj tshuaj yuav ua rau ib tug sib txawv ntawm cov tsiv thiab zoo li qub pwm, uas yuav inevitably ua rau ib tug ya burr. Tshwj xeeb tshaj yog thaum lub rooj vag sab yog muab tso rau ntawm lub qhov nyob ze ntawm qhov chaw ntawm qhov chaw, lub burr yog heev tshwm sim vim hais tias ntawm lub siab txhaj tshuaj yuav tsum tau rau lub rooj vag molding no.


2. Cov pwm hauv zos haum tsis nruj

Cov pwm nws tus kheej yog nruj nreem molded, tab sis thaum lub tshuab txhaj tshuaj molding tshuab txais lub luj tshib hom pwm clamping mechanism, feem ntau yog vim tsis zoo parallelism ntawm pwm los yog tsis zoo hloov ntawm cov pwm clamping ntaus ntawv, qhov tshwm sim ntawm unbalanced pwm clampings xws li sab laug. thiab sab xis, uas yog, sab laug thiab sab xis nkaus xwb - sab yog xauv, sab nraud tsis nyob ze, lub sijhawm no yuav tsum tau kho cov hlua khi (ob lossis plaub txiav) kom nws sib npaug.
Qhov thib ob, kuj tseem muaj pwm nws tus kheej vim qhov kev tshawb fawb tsis zoo thiab kev sib txuam los ntawm kev sib xyaw kom nruj tsis nruj. Tshwj xeeb tshaj yog thaum muaj molding qhov nyob rau hauv nruab nrab ntawm ib feem, vim lub luag hauj lwm txhawb nqa ntawm qhov no, thaum lub clamping quab yuam tsis txaus, nws kuj yog ib qho yooj yim mus tshwm burrs.

Lwm qhov yog zawv zawg tub ntxhais vim hais tias raws li cov tub ntxhais txav mus yog qhov kev ua haujlwm, uas feem ntau ua rau burrs, yog li cov tub ntxhais zawv zawg yog qhov tseem ceeb heev. Tshwj xeeb tshaj yog rau sab laug thiab txoj cai parting haters, sab projection cheeb tsam kuj raug molding siab, thiab yog hais tias tus tsim tsis muaj peev xwm tiv taus qhov siab no, burrs feem ntau tshwm sim. Hais txog qhov sib txawv ntawm qhov ntxig thiab lub qhov ntawm lub ejector, nws yuav tsis tsuas yog tsim cov phenomenon ntawm nce burr vicious vajvoog, tab sis kuj nce lub ejector kuj.

3. tshwm sim los ntawm pwm flexing

Yog hais tias tus thawj degree ntawm pwm tsis txaus, qhov txhaj tshuaj yuav tsim deflection, yog hais tias muaj ib lub qhov nyob ze ntawm qhov chaw, burrs yuav generated nyob ib ncig ntawm lub qhov; kuj thaum lub qhov nruab nrab yog siv los qhib lub qhov rooj sab, burrs yuav raug generated nyob ib ncig ntawm lub qhov thiab lub sprue. Burrs los ntawm qhov ua rau yog tshwm sim los ntawm cov pwm ua tsis zoo, yog li lawv nyuaj kho dua. Lub burr tuaj yeem raug txo los ntawm kev txhawb nqa pwm.

4. Yas flowability yog zoo heev

Txoj kev xav, nws tsis yog qhov ua rau burr yog tias cov yas ntws zoo dhau ib leeg. Txawm li cas los xij, thaum cov yas ntws zoo dhau lawm, cov yas tuaj yeem nkag mus rau hauv qhov sib txawv me me, yog li nws yooj yim heev kom muaj burrs. Txhawm rau tshem tawm qhov burr no, koj tuaj yeem txo qhov kub thiab txias los yog txhaj tshuaj, los yog txo cov pwm kub los yog txhaj tshuaj ceev.

5. Kev txhaj tshuaj ntau dhau ntawm cov khoom siv yaj

Qhov no kuj tsis yog qhov ncaj qha ua rau burrs. Nws yog qhov tsis ncaj ncees rau kev txhaj tshuaj ntau dhau los txhawm rau txhawm rau tiv thaiv kev poob qis thiab yuav tsum tau coj los ua kom lub sijhawm txhaj tshuaj lossis tuav lub sijhawm rau pwm (saib rau shrinkage).

6. Cov khoom txawv teb chaws ntawm cov pwm nto

Cov khoom txawv teb chaws ntawm cov pwm saum npoo yog khi los tsim cov burrs. Yuav kom daws tau qhov teeb meem no, nws yog qhov pom tseeb tias qhov saum npoo ntawm pwm yuav tsum tau ntxuav kom cov pwm nto ze.

Thib peb, cov tshuaj burr

Yog tias pom qhov tshwm sim tshwm sim tshwm sim, tus tswv ntawm cov txheej txheem txhaj tshuaj molding yuav tsum nres qhov kev puas tsuaj rau lub sijhawm, nrhiav qhov ua rau ntxov thiab muab kev daws teeb meem.

1, Tsis txhob siv lub siab txhaj tshuaj ntau dhau hauv cov txheej txheem txhaj tshuaj

2, Txhim kho lub zog clamping

3, Kho lub ntim ntim thiab txo qhov kub

MINDWELL tshwj xeeb hauvPlastic Moulding Services, peb cov engineers muaj peev xwm daws tau cov teeb meem ntawm kev txhaj tshuaj molded qhov chaw. Qhov tshwm sim ntawm burr yuav ncaj qha ua rau cov teeb meem zoo ntawm kev txhaj tshuaj molded cov khoom, uas tuaj yeem kho tau hauv cov teeb meem teeb meem, lossis ncaj qha ua rau cov khoom seem ntawm cov khoom hnyav. Yog tias pom ya burr thaum pib, cov pwm yuav tsum tau kho kom sai li sai tau.
