Tsim Txhaj Pwm rau Phau Ntawv C Plhaub
Lub plhaub phau ntawv tau muab faib ua plaub ntu: A, B, C thiab D. Phau Ntawv A plhaub: lub hau saum toj kawg nkaus ntawm lub vijtsam zaub, lub hau loj, yog lub plhaub A, raws li pom hauv daim duab 1(a). Phau ntawv B plhaub: lub thav duab sab hauv lub vijtsam (thaum saib lub vijtsam, sab ntawm nws), raws li pom hauv daim duab 1(b). Phau ntawv C plhaub: Lub plhaub nyob ib sab ntawm cov keyboard yog C plhaub. Txoj hauj lwm ntawm tes so yog qhia hauv daim duab 1(c). Phau ntawv D plhaub: Lub hauv qab ntawm lub tshuab yog nyob rau hauv kev sib cuag nrog lub desktop ntawm lub plhaub D, raws li qhia hauv daim duab 1(d). Lub plhaub phau ntawv yog cov nqa thiab tiv thaiv lub plhaub ntawm lub ntsiab board, processor thiab lwm yam khoom siv ua haujlwm. Nws suav nrog ntau qhov tseem ceeb xws li cov txheej txheem tsim, cov khoom siv, ntim tswj, tswj qhov hnyav, tswj cov cua sov dissipation, ruaj khov, kev nyab xeeb, thiab kev tiv thaiv ib puag ncig. Cov ntaub ntawv ntawm lub plhaub muaj xws li ABS engineering plastics, magnesium aluminium alloy, titanium alloy, carbon fiber alloy, PC-GF (polycarbonate PC), thiab lwm yam. Ntawm lawv, PC ntxiv rau ABS thiab aluminium-magnesium alloy yog qhov ntau tshaj, thiab ob qho no kuj yog feem ntau siv. Phau ntawv plhaub khoom. Kab lus no qhia txog pwm tsim ntawm phau ntawv C plhaub ua los ntawm PC ntxiv rau ABS.
2. Kev tshuaj xyuas cov khoom
Cov khoom duab ntawm phau ntawv C plhaub yog pom hauv daim duab 1. Qhov siab tshaj plaws ntawm cov yas yog 276.50 hli X 228.30 hli X 9.30 hli, qhov nruab nrab tuab ntawm cov yas yog 1.50 hli, lub thickness ntawm khawm thaj tsam yog 1.20 hli, thiab qhov hnyav ntawm cov yas yog 78.5 grams. Cov khoom siv yog PC ntxiv rau ABS, tus nqi shrinkage yog 0.37 feem pua.
Cov kev xav tau ntawm cov khoom yas yog tias yuav tsum tsis muaj kev txhaj tshuaj tsis zoo thiab tsis muaj kev sib tsoo lossis deformation ntawm cov khoom yas. PC ntxiv rau ABS muab qhov zoo ntawm PC thiab ABS. Piv nrog rau PC, PC ntxiv rau ABS alloy feem ntau txhim kho yaj fluidity, formability, electroplating thiab tsos. Piv nrog ABS, nws tsuas yog txhim kho cov cua sov ua haujlwm, cuam tshuam tsis kam thiab rigidity ntawm nyias-walled khoom.
PC ntxiv rau ABS yuav tsum tau qhuav ua ntej molding kom txo cov dej ntsiab lus ntawm cov khoom mus rau hauv qab no {{0}}.05 feem pua , nyiam dua hauv qab 0.02 feem pua, txhawm rau txhim kho kev ruaj ntseg thiab cov khoom siv kho tshuab. Siv lub tshuab pwm kub los tswj pwm kub thaum molding PC ntxiv rau ABS. Qhov pom zoo pwm kub yog 50-80 degree . Cov pwm kub siab dua tuaj yeem tsim cov dej ntws zoo, siab dua vuam kab zog, thiab cov khoom qis hauv kev ntxhov siab, tab sis lub voj voog molding yuav ntev. Yog tias pwm kub qis dua qhov pom zoo, nws yuav ua rau muaj kev ntxhov siab sab hauv thiab ua rau qhov kev ua tau zoo tshaj plaws ntawm qhov chaw. Raws li deb ntawm qhov chaw ntawm qhov chaw thiab lub voj voog lub sij hawm muaj kev txhawj xeeb, thaum pwm kub nyob rau hauv nruab nrab ntawm qhov pom zoo kub ntau, cov txiaj ntsig zoo tuaj yeem xav tau.
Ob qhov ntawm cov khoom yas yuav tsum tau tsim nrog cov tub ntxhais rub tawm, thiab ob lub buckles ntawm ntug ntawm lub qhov rais ntawm nruab nrab nas kov npo yuav tsum tau tsim nrog inclined sab saum toj molding, raws li qhia hauv daim duab 2.
3. Cov ntsiab lus tseem ceeb ntawm pwm tsim
3.1 Cov kab noj hniav
Qhov loj ntawm cov khoom yas yog qhov loj, thiab lub tshuab txhaj tshuaj moulding tonnage yuav tsum loj, yog li tsuas yog ib kab noj hniav layout tuaj yeem tsim. Cov pwm tsim yog pom hauv daim duab 3. Cov pwm pwm yog FCI4550A80B110C120. Plaub sab yog nruab nrog xoom-degree sab locks kom meej qhov chaw. Lub tshuab txhaj tshuaj molding tau xaiv yog 250-tuj txhaj tshuaj molding tshuab. Tom qab kev xam, lub peev xwm plasticizing thiab clamping quab yuam ua tau raws li qhov yuav tsum tau ua.
3.2 Tsim cov txheej txheem pouring
Cov khoom yas yog qhov loj me thiab muaj nyob rau hauv cov plhaub nyias nyias. Qhov ntev ntawm cov khoom yas yog qhov loj. Yog li ntawd, nws yog ib qho tseem ceeb los txiav txim qhov chaw thiab tus naj npawb ntawm cov rooj vag. Hauv kev tsim pwm, 8 cov ntsiab lus ntawm cov kua nplaum raug xaiv, saib cov pwm tsim cov duab kos. Ntawm lawv, cov kua nplaum yog txhaj rau hauv lub rooj vag thaum 6 teev tsaus ntuj ntawm lub keyboard txoj hauj lwm, thiab lub rooj vag tsis muaj nyob rau hauv daim duab 7. Lwm ob lub ntsiab lus yog qhov loj nozzle lap lo lo lo lo lo ntxhuav, raws li qhia hauv daim duab 8.
3.3 Lateral core rub qhov system tsim
Lub 2 sliders yog me me, yog li xaiv lub rear pwm slider uas tau tsav los ntawm inclined qhia kem los rub cov tub ntxhais. Ob lub ru tsev inclined yog lub ru tsev inclined nrog T-slot zawv zawg.
3.4 Ntxig tsim
Qhov loj ntawm lub hauv ntej thiab nram qab pwm cores yog loj, thiab nws yog ib qho nyuaj rau ncaj qha mus rau hauv lub zoo thav duab ntawm lub template. Yog li ntawd, pem hauv ntej thiab nram qab pwm cores yog feem ntau tsim nrog compression blocks, raws li cov ntaub ntawv lub kaum sab xis, ob sab deb ntawm lub reference lub kaum sab xis, lub puab ncej yog nce los ntawm 1 hli, nias nyob rau hauv lub nyem block. Muaj ob txoj hauv kev rau kev ntxig me me ntawm lub nraub qaum pwm, ib qho yog lub rooj dai thiab lwm qhov yog taper, txhua tus muaj nws tus yam ntxwv. Kev tsim ntawm lub rooj me me hanging lub rooj muaj ntau yam zoo: ib qho yog tias nws tshem tawm qhov drilling thiab tapping ntawm pwm puag thiab ntxig; Qhov thib ob yog ua kom yooj yim rau kev ua haujlwm ntawm pwm sib dhos; qhov thib peb yog kom tsis txhob muaj qhov ploj ntawm cov ntsia hlau. Cov ntsiab lus tseem ceeb ntawm kev tsim lub platform dai yog raws li hauv qab no: (1) Lub hanging platform ntawm lub insert yuav tsum tau xaiv nyob rau hauv ntev sab ntawm lub insert, thaum zam lub nkhaus ib feem. (2) Nws yog ib qho tsim nyog los xyuas kom meej tias lub rooj dai thiab nws qhov chaw tuaj yeem yog hauv av lossis xaim-txiav. (3) Lub luv luv dai platform yuav tsum zam lub tiaj tus pas nrig sab saum toj kom tsis txhob cuam tshuam. (4) Nyob rau hauv luv luv, tus tsim ntawm lub rooj dai yuav tsum xav txog cov txheej txheem txheej txheem, tsis yog arbitrarily tsim. (5) Thaum muaj lub nplhaib roj hmab nqa dej hauv qab ntawm qhov ntxig, tsis txhob siv lub platform dai, tab sis kho nws nrog cov ntsia hlau los tiv thaiv cov dej tawm.
