BMC Sink Mould

I. Kev txhais thiab daim ntawv thov

BMC dab dej pwmyog cov cuab yeej tshwj xeeb tshwj xeeb tsim los rau compression / hloov molding ntawm BMC (Bulk Molding Compound) cov khoom siv sib xyaw, feem ntau yog rau chav ua noj thiab chav dej. BMC cov ntaub ntawv yog tsim los ntawm unsaturated polyester cob, tws iav fiber ntau, ntxhia fillers, thiab ntau yam additives. Cov dab dej tsim los ntawm cov pwm ua los ntawm cov khoom siv BMC muaj cov txiaj ntsig zoo xws li kev ua haujlwm siab, kev tiv thaiv corrosion, kub tsis kam, qis shrinkage, thiab ib tug du nto, zoo hloov cov tsoos stainless hlau thiab ceramic dab dej. Qhov sib thooj BMC dab dej pwm yuav tsum tiv taus qhov kub thiab txias, kev kub siab, thiab kev puas tsuaj ntawm cov iav fibers thaum lub sij hawm molding txheej txheem ntev, thiab yog li poob rau hauv qeb siab -precision kub- xovxwm pwm.

II. Core Design Parameters thiab Structure

1.Cavity thiab parting nto

Shrinkage them nyiaj:Lub shrinkage tus nqi ntawm BMC yog 0.2% - 0.8%, thiab cov pwm kab noj hniav yuav tsum tau them nyiaj rau qhov kev taw qhia ntawm qhov loj me; iav polishing nrog Ra Tsawg dua lossis sib npaug ntawm 0.4μm txhawm rau txhim kho qhov zoo nkauj ntawm lub tank dej.

Draft angle:1℃-2℃(lub puab sab hauv tuaj yeem me me, thaum lub npoo sab nrauv yuav tsum txaus) kom tsis txhob muaj pwm lo thiab ntug chipping.

Qhov kev sib cais yuav tsum yog lub dav hlau ua qhov tseem ceeb. Rau cov txheej txheem nyuaj, kev sib cais yuav tsum tau siv, thiab flash yuav tsum tau tswj los ntawm kev sib piv cov hlaws.

2. Cov Khoom Siv Hluav Taws Xob:Kev kho yuav tso tawm cov pa roj me me. Thaum kawg ntws, tav txoj hauj lwm, thiab cov ces kaum, tso grooves nrog ib tug tob ntawm 0.01-0.03mm (dav 3-5mm) yuav tsum tau teem. Rau lub tank dej loj, lub tshuab nqus tsev - tuaj yeem siv tau. Nws yog nruj me ntsis txwv tsis pub rau cov pa grooves kom tob heev, uas yuav ua rau overflow.

3. Kev tswj qhov kub thiab txias:Pwm kub 140-160 degree, nrog kub sib txawv tswj nyob rau hauv ± 5 degree; zonal kub tswj ( rooj vag thiab cov phab ntsa tuab ntawm nws tus kheej tswj), rhuab los ntawm cua sov rods / roj ncig, nrog ntau yam thermocouple xyuas cov ntsiab lus; tiv thaiv kom tsis txhob muaj cua sov hauv zos thiab kho tsis sib xws.

4. Kev tshem tawm thiab kev taw qhia:Hnav -cov ntawv qhia cov pins thiab bushings (HRC{1}}) yog siv. Ejector pins yog sib npaug ntawm qhov tsis yog - pom qhov muag kom tsis txhob deformation thaum ejection. Rau cov pwm loj, ib qho rov qab mechanism thiab kev ruaj ntseg xauv yog ntxiv.

5. Rooj vag thiab khiav:Cov pwm hloov pauv siv lub voj voog loj khiav + kiv cua-zoo li tus / sab rooj vag. Tus neeg khiav dej num yuav tsum tau ua kom du thiab muaj tus ntoo khaub lig txaus -sectional cheeb tsam; BMC muaj viscosity siab, yog li zam kom tsis txhob ntev thiab nqaim khiav kom txo tau qhov tsis kam.

III. Cov khoom siv pwm thiab kev kho deg

IV. Cov ntsiab lus tseem ceeb ntawm txoj kev tsim

1. Pub mis:Preheat BMC cov khoom rau 40-60℃thiab pub nws kom muaj nuj nqis (feem ntau yuav ua rau flash, pub mis tsis txaus yuav ua rau cov khoom tsis txaus).

2. Moulding thiab siab:Chav tsev siab siab yuav tsum yog 30-50MPa. Cov dej tank loj yuav tsum muaj cov xovxwm hydraulic loj.

3. Kev kho:Kho ntawm ib ncig ntawm 145 degree. Lub sijhawm kho yog xam raws li qhov siab tshaj plaws phab ntsa thickness (1.2–1.5 min / mm).

4. Demolding thiab post-kev kho mob:Demold thaum kub poob qis dua 80 degree. Tshem lub flash thiab siv cov matte lossis antibacterial txheej yog tias tsim nyog.

V. Tej yam tsis zoo thiab kev daws teeb meem

1. Npuas / Pinholes:Qhov cua tsis txaus lossis pwm kub qis dhau → Ua kom qhov cua nkag mus tob, nce pwm kub, thiab qhib lub tshuab nqus tsev.

2. Ntau dhau flash:Tsis sib npaug clamping siab los yog dhau qhov sib sib zog nqus vent channels → Kho lub siab, ua kom zoo dua qhov chaw, thiab txo qhov cua channel thickness.

3. Nto flow marks:Kev ua kom tsis zoo los yog qhov kub tsis sib xws → Kho qhov kev txhaj tshuaj / ntim ceev, thiab siv cov kev tswj qhov kub thiab txias.

4. Pwm nplaum:Lub kaum sab xis tsis txaus lossis tsis ua tiav qhov kev kho mob → Ua kom lub kaum sab xis, thiab rov ua dua chrome plating / PVD txheej.

VI. Pwm tu thiab tu

1. Txhua zaus lub tshuab raug kaw rau kev ntxuav cov kab noj hniav, siv cov tshuaj ntxuav tu kom tshem tawm cov residue residue. Tsis txhob khawb daim iav nto nrog cov cuab yeej nyuaj.

2. Tsis tu ncua xyuas lub lubrication ntawm cov lus qhia pins thiab ejector pins, nrog rau calibrate lub cua sov system thiab kub tswj qhov tseeb.

3. Yog tias lub tshuab tsis siv lub sijhawm ntev, kev siv tshuaj tiv thaiv - xeb yuav tsum tau ua thiab nws yuav tsum tau muab kaw thiab khaws cia rau hauv qhov chaw qhuav.

VII. Xaus

Raws li cov tub ntxhais precision kub- nias lub cuab yeej rau molding ntawm BMC dab dej, tus tsim rationality, kev xaiv cov khoom siv science, txheej txheem txheem, thiab raws sij hawm txij nkawm ntawm BMC dab dej pwm ncaj qha txiav txim lub molding zoo, ntau lawm efficiency, thiab kev pab cuam lub neej ntawm BMC dab dej. Hauv kev siv cov tswv yim, peb lub ntsiab lus tseem ceeb yuav tsum tau tswj xyuas nruj me ntsis: ua ntej, tswj cov nqi shrinkage ntawm BMC cov ntaub ntawv thiab txhim kho cov kab noj hniav kom zoo; thib ob, xyuas kom meej qhov sib xws ntawm pwm qhov kub thiab txias kom tsis txhob muaj pwm pwm; thib peb, tsim nyog xaiv cov pwm hlau thiab cov txheej txheem kho saum npoo raws li qhov ntim ntau lawm, ntsuas tus nqi thiab kev pabcuam lub neej. Nyob rau tib lub sijhawm, kev tu tsis tu ncua, lubrication, thiab calibration ntawm cov pwm tuaj yeem ua rau lawv lub neej ua haujlwm tau zoo thiab txo cov nqi tsim khoom. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum paub meej txog qhov sib txawv ntawm BMC thiab SMC cov ntaub ntawv. BMC cov ntaub ntawv yog tsim nyog rau nyias-walled, complex-zoo li tus, thiab siab-surface-precision me dab dej. Cov pwm tsim tsim yuav tsum tsom mus rau qhov tso pa tawm thiab tswj qhov kub thiab txias kom ntseeg tau tias cov khoom molded ua tau raws li daim ntawv thov ntawm chav ua noj thiab chav dej.
