Tsheb Rooj Vaj Huam Sib Luag Pwm

I. Cov khoom thiab cov khoom siv

Tej qhov ntev:kwv yees li 800–1200 mm (ntev × dav), qhov tob 100–150 mm, phab ntsa thickness 2.5–3.0 mm.

Cov khoom siv:

• PP + EPDM / T20:Zoo toughness, tsis tshua muaj nqi, shrinkage tus nqi kwv yees li 1.011-1.018.
• ABS / PC + ABS:High rigidity, zoo heev nto zoo, shrinkage tus nqi kwv yees li 1.006-1.010.
• Cov kev xav tau tshwm sim:Uniform kev ntxhib los mos (Ra 0.8-1.6 μm), tsis muaj qhov sib txuas, cov cim shrinkage, cov qhab nia ntawm lub rooj vag, thiab qhov demolding txoj kab nqes loj dua los yog sib npaug li 5℃(ntawm qhov pom qhov chaw).

II. Pwm Qauv Tsim

1. Pwm puag thiab cov khoom siv

o Pwm puag:Standard loj pwm puag (xws li H13, P20), integral A / B daim hlau, kom ntseeg tau rigidity thiab precision.

o Cavity/core:S136 los yog NAK80, ua ntej-hardened rau HRC 48–52, nto polished rau Ra Tsawg dua los yog sib npaug rau 0.2 μm.

 

2. Rooj vag System

o Kub khiav + kev tswj lub valve:8-12 kub nozzles, faib raws li qhov ntws gradient kom muaj kev sib npaug.

o Rooj vag:Ntxuam- lub rooj vag zoo li lub rooj vag lossis lub rooj vag sab, muab zais rau ntawm qhov tsis pom - pom qhov chaw kom tsis txhob muaj cov cim.

o Tus khiav:Txoj kab uas hla φ8–10 mm, ncig hla-section, polished rau Ra 0.2 μm, siab poob qis dua lossis sib npaug li 15 MPa.

 

3. Cua txias System

o Conformal water channels:Txoj kab uas hla φ12–14 mm, qhov sib nrug 20–30 mm, ze rau ntawm kab noj hniav, kom ntseeg tau qhov kub ntawm qhov sib txawv tsawg dua lossis sib npaug ± 2 degree.

o Tswb-puab mesh / tav cheeb tsam:Siv dej- thaiv cov phiaj los yog tshwj xeeb- cov kab dej zoo li lub cev kom tsis txhob muaj cua sov hauv zos thiab deformation.

 

4. Core-rub thiab Ejection Mechanism

o Sliders (sab cores):Rau undercuts xws li lub qhov rais thav duab thiab handrails, nrog ib tug stroke ntawm 25-35 mm thiab ib tug kaum sab xis ntawm 12℃-18 degree, hydraulically tsav thiab nitrogen gas xauv.

o Rockers:Rau sab hauv latches thiab grooves, nrog lub kaum sab xis ntawm 8℃-12 degree, coj los ntawm hnav- cov phaj tiv thaiv kom tsis txhob muaj teeb meem thiab flash.

o Ejection system:Muaj cov ejector blocks, ejector pins, thiab rockers, nrog 4-6 nitrogen gas springs rau ejection kom zoo ib yam quab yuam thiab tsis deformation.

 

5. Kev taw qhia thiab qhov chaw

Square qhia pins + taper positioning:10℃taper nyob ib ncig ntawm plaub sab ntawm A / B daim hlau, nrog hnav- tiv thaiv thaiv kom tsis txhob pwm nthuav dav thiab tsis zoo.

Kub khiav kev tiv thaiv:Cov lus qhia pins yog 20 mm lossis ntau dua saum lub taub hau kub kom tsis txhob muaj kev puas tsuaj.

 

III. Cov ntsiab lus tseem ceeb

Kev Tswj Xyuas Zoo

Tshem tawm cov kab weld:Sequential valve kub khiav, tswj kev txhaj tshuaj ib ntus kom txav cov kab vuam mus rau qhov tsis pom - pom.

Uniformity ntawm kev ntxhib los mos:Raws li qhov sib txawv etching qhov tob, deg hardness Ntau dua los yog sib npaug rau HRC 48, gloss txawv <3% tom qab 100,000 daim hauv ntau lawm.

Venting optimization:Qhib qhov qhib qhov (0.02–0.03 mm sib sib zog nqus) ntawm cov kab sib cais, cov sliders, thiab inclined cores kom tsis txhob hlawv thiab txhaj tshuaj luv luv.

 

Deformation tswj

Shrinkage them nyiaj:Txhawb qhov sib txawv ntawm thaj chaw (xws li, 1.016 rau qhov chaw textured, 1.020 rau snap- haum qhov).

Cooling balance:Optimize cov dej raws los ntawm cov pwm ntws tsom xam kom ntseeg tau tias txias txias thiab txo cov kev ntxhov siab sab hauv.

Ejection balance:Siv ntau-point synchronized ejection los tiv thaiv kev quab yuam hauv zos thiab warpage.

 

Lub neej thiab kev tu

Kev kho saum npoo: Hard chrome lossis nano{0}} txheej txheej ntawm cov kab noj hniav txhawm rau txhim kho kev hnav tsis kam thiab corrosion kuj, nrog lub neej ntev dua los yog sib npaug rau 1.2 lab pwm cycles.

Hnav cov khoom: Sliders, inclined cores, thiab inserts yog tsim los detachable rau yooj yim hloov thiab txij nkawm.
