Txhaj Pwm Rau Tsheb Cav Hood

Kev txhaj tshuaj pwm rau lub tsheb cav hood yog ib qho tshwj xeeb precision pwm siv rau kev tsim khoom loj ntawm lub tsheb cav sab nrauv / sab hauv lub phaj. Lub hauv paus ntawm cov pwm no yog tsim los ntawm siab - kev txhaj tshuaj ntawm cov khoom siv thermoplastic (xws li PA6+GF, PP-T20), ntsib lub tsheb- qib yuav tsum tau muaj xws li qhov tseeb qhov tseeb ntawm ± 0.2mm, A-chav kawm nto, thiab siab - kub tsis kam ntawm -40℃rau 140℃.

 

I. Zuag qhia tag nrho Tsim ntawm Pwm

1. Cavity Layout

Txuj kev daws teeb meem:Ib lub pwm nrog ib kab noj hniav (rau cov khoom loj nrog cov qauv tsim thiab ntau lub hauv paus- rub cov kev xav tau).

Cov npog me me:Ib lub pwm nrog ob kab noj hniav (balanced layout).

 

2. Parting Surface Design

Txoj Cai:Xaiv qhov loj tshaj plaws contour ntawm cov khoom, coj mus rau hauv tus account demolding, venting, thiab processability.

Common rau cav npog:Planar parting ntawm qhov qis tshaj plaws, ua ke nrog kev tho hauv zos lossis kev kho mob abutment rau qhov siab sib txawv.

 

3. Moulding Parts (Core / Cavity)

Khoom siv:Feem ntau siv rau cov kab noj hniav thiab cov cores yog P20, 718H, thiab 2738 (pre- hardened HRC32 ~ 38); rau sliders thiab inclined cores, SKD61 thiab H13 (quenched HRC50 ~ 54) yog siv.

Qauv:Cov cheeb tsam nyuaj yog modularized (rau kev yooj yim ntawm kev ua, txij nkawm, thiab qhov cua); xyuas kom cov phab ntsa tuab tuab thiab sib npaug txias.

 

 

II. Key System Design

1.Pouring system (tsuas yog kub khiav)

Hom:Kub khiav + txias khiav ntau- taw tes rooj vag txhaj tshuaj (5 mus rau 8 sab rooj vag / taw tes rooj vag).

Muaj nuj nqi:Sib npaug sib npaug rau qhov chaw tiaj tus loj, tiv thaiv kev txhaj tshuaj luv luv, txo cov kab txuas, thiab txo qis hauv kev ntxhov siab.

Tsim:Kev xaiv rooj vag ntawm qhov tsis yog - pom qhov chaw thiab ntawm phab ntsa tuab; nruab nrog txias slug qhov dej; Kub khiav kub tswj yog qhov tseeb (± 1 degree).

 

2. Lateral Core- rub thiab Demolding

·Snap-fit / Interlocking:Oblique core pin (oblique ejector tus pin) (lub kaum sab xis 3℃~ 8 degree).

· Sab qhov / Sab qhov chaw:Oblique qhia tus pin slider / Bent tus pin slider (hnav- tiv thaiv thaiv, quenched daim ntawv qhia nto).

· Kev tshem tawm:Kev sib xyaw ntawm ejector tus pin + ejector raj + ejector thaiv; nruab nrog ua ntej - rov pib dua thiab tiv thaiv -dawb cim qauv.

 

3. Kev tswj qhov kub thiab txias (txias).

· Conformal cua txias raws (8 ~ 12 hli los ntawm kab noj hniav), txoj kab uas hla 8 ~ 12 hli, qhov kub thiab txias sib txawv ntawm qhov hluav taws xob qhov hluav taws xob tsawg dua los yog sib npaug li 2 degree.

·Lub hom phiaj:Kev ua kom txias txias, ua kom luv luv (45 ~ 60s), txo qhov kev sib tsoo ntawm qhov sib tsoo.

 

4. Kev taw qhia thiab Exhaust

·Kev taw qhia:4 teeb ntawm kev qhia pins thiab bushings + conical nto positioning (pwm kaw qhov tseeb ± 0.02mm).

·Qhov cua:Venting grooves ntawm qhov chaw parting (0.02 ~ 0.05mm sib sib zog nqus) + venting los ntawm qhov sib txawv ntawm inserts thiab ejector pins; cov tso tawm tso tawm yog teem rau hauv qhov chaw huab cua nyob rau qhov kawg.

 

 

III. Cov ntsiab lus tseem ceeb ntawm kev tsim thiab tsim khoom

1. Moldflow Analysis:Validate filling, tuav lub siab, txias, warpage, thiab optimize lub rooj vag thiab txheej txheem.

2. Kev ua haujlwm:High-milling ceev (HSK-E63), iav EDM, qhov tob qhov drilling; nto polishing Ra Tsawg dua lossis sib npaug li 0.8 μm.

3. Pwm sim:Tsom ntsoov rau kev lees paub qhov filling, warpage, core - rub smoothness, thiab tsos tsis xws luag.

4. Taizhou Huangyan Jiutai PwmCo., Ltd. tshwj xeeb hauv tsheb cav hood pwm, txais yuav kub khiav, txias txias, thiab modular core- rub, haum rau PP / PA + GF cov ntaub ntawv, ua tau raws li qhov yuav tsum tau ntawm ib lab pwm cycles thiab lightweighting rau tshiab zog tsheb.
