Yuav ua li cas xaiv lub tshuab txhaj tshuaj thib ob

Yuav xaiv li cas a thib ob-tes txhaj tshuaj molding tshuab

Cov yam tseem ceeb uas feem ntau cuam tshuam rau kev xaiv ntawm kev txhaj tshuaj molding tshuab suav nrog pwm, khoom, yas, molding yuav tsum tau, lwm yam. Yog li ntawd, cov ntaub ntawv hauv qab no yuav tsum tau sau lossis tau txais ua ntej xaiv: 1. Pwm loj (dav, qhov siab, tuab) , qhov hnyav, tsim tshwj xeeb, lwm yam.; 2. Hom thiab ntau npaum li cas ntawm cov yas siv (ib qho khoom siv raw lossis ntau yam yas); 3. Qhov loj me (ntev, dav, qhov siab, tuab) thiab qhov hnyav ntawm cov khoom txhaj tshuaj molded; 4. Moulding xav tau, xws li Quality condition, ntau lawm ceev, lwm yam. Tom qab tau txais cov ntaub ntawv saum toj no, koj tuaj yeem ua raws li cov kauj ruam hauv qab no los xaiv lub tshuab yas txhaj tshuaj molding:

1. Xaiv txoj cai hom:

Txij li thaum muaj ntau hom kev txhaj tshuaj molding tshuab thib ob, Nws yog ib qho tsim nyog yuav tsum txiav txim siab seb hom kev txhaj tshuaj molding tshuab twg yog qhov twg cov khoom yuav tsum tau ua thaum pib, xws li cov khoom siv thermoplastic lossis bakelite raw khoom lossis PET raw khoom, lwm yam., yog ib leeg-xim, ob xim, ntau xim, interlayer lossis xim sib xyaw, lwm yam.

Ntxiv thiab, qee cov khoom xav tau kev ruaj ntseg siab (kaw lub voj), siab precision, ultra-siab txhaj tshuaj, kev txhaj tshuaj siab lossis kev tsim khoom sai (ntau lub voj), lwm yam., thiab cov ntawv tsim nyog yuav tsum tau xaiv rau kev tsim khoom.

2. Yuav haum lub txhaj tshuaj pwm:

Txiav txim seb puas yog “loj kab sab hauv”, “pwm thickness”, “yam tsawg kawg nkaus pwm loj” thiab “pwm phaj loj” ntawm lub tshuab yog tsim nyog raws li pwm loj, thiaj li paub meej tias cov pwm tuaj yeem muab tso rau.

Nco tseg: ① Qhov dav thiab qhov siab ntawm cov pwm yuav tsum me dua los yog tsawg kawg yog ib sab me dua li sab hauv ntawm kab loj; ② Qhov dav thiab qhov siab ntawm cov pwm yuav tsum zoo dua nyob rau hauv qhov loj ntawm cov pwm phaj; ③ Lub thickness ntawm pwm yuav tsum nyob nruab nrab ntawm cov pwm tuab ntawm lub tshuab txhaj tshuaj molding; ④ Qhov dav thiab qhov siab ntawm cov pwm yuav tsum tau raws li qhov tsawg kawg nkaus pwm loj pom zoo los ntawm lub tshuab txhaj tshuaj molding, thiab nws tsis tsim nyog yog tias nws tsawg dhau.

3. Tshem tawm txhaj tshuaj molding khoom:

Txiav txim seb puas yog “pwm qhib mob stroke” thiab “pwm ejection stroke” txaus rau cov khoom tiav kom tshem tawm los ntawm cov pwm thiab cov khoom tiav.

① Lub pwm qhib stroke yuav tsum yog tsawg kawg ob zaug ntawm qhov siab ntawm cov khoom tiav nyob rau hauv cov kev taw qhia ntawm qhib thiab kaw lub pwm, thiab yuav tsum suav nrog qhov ntev ntawm qhov ntsug sprue;

② Lub ejection stroke yuav tsum txaus kom tshem tawm cov khoom tiav.

4. Yuav xauv lub yas daws:

Lub tonnage ntawm “quab yuam quab yuam” yog txiav txim siab los ntawm cov khoom thiab yas.

Thaum cov khoom siv raw yog txhaj rau hauv pwm kab noj hniav ntawm kev kub siab, nws yuav tsim ib lub zog los txhawb cov pwm. Yog li ntawd, chav clamping ntawm lub tshuab txhaj tshuaj molding yuav tsum muab txaus “quab yuam quab yuam” kom cov pwm tsis raug ncab. Kev suav ntawm qhov yuav tsum tau muaj zog clamping yog raws li hauv qab no:

① Tau txais qhov projected cheeb tsam ntawm cov khoom tiav nyob rau hauv cov kev taw qhia ntawm qhib thiab kaw pwm los ntawm cov tsos loj ntawm cov khoom tiav; /cm2 ua); ③ Lub siab nyob hauv pwm txawv nrog cov khoom siv raw, thiab cov khoom siv raw yog 350 ~ 400kg/cm2; ntau dua ob npaug. Txog tam sim no, cov lus qhia tshwj xeeb ntawm chav clamping tau txiav txim siab ua ntej, thiab qhov hnyav ntawm tus qauv tau txiav txim siab ntxaws. Ces, cov kauj ruam hauv qab no yuav tsum tau ua kom paub tseeb tias qhov chaw txhaj tshuaj twg muaj qhov haum ntsia hlau taub.

5. Tua kom puv txhaj tshuaj pwm kab noj hniav:

Txiav txim siab qhov yuav tsum tau ua “txhaj tshuaj ntim” thiab xaiv qhov tsim nyog “ntsia hlau taub” raws li qhov hnyav ntawm cov khoom tiav thiab tus naj npawb ntawm cov kab noj hniav pwm.

Txhawm rau xam qhov hnyav ntawm cov khoom tiav, tus naj npawb ntawm pwm kab noj hniav (ib lub pwm nrog ob peb kab noj hniav) yuav tsum tau xav txog;

Rau lub hom phiaj ntawm stability, qhov ntim tshuaj yuav tsum ntau dua 1.35 lub sij hawm qhov hnyav ntawm cov khoom tiav, yog, qhov hnyav ntawm cov khoom tiav yuav tsum nyob hauv 75% ntawm qhov ntim tshuaj.

6. Txhaj tshuaj tsis haum ntawm kev txhaj tshuaj molding tshuab:

Cov xwm txheej xws li “ntsia hlau compression piv” thiab “txhaj tshuaj siab” raug txiav txim los ntawm cov yas. Qee cov yas engineering xav tau kev txhaj tshuaj ntau dua thiab tsim cov ntsia hlau compression piv tsim kom muaj cov nyhuv molding zoo dua. Yog li ntawd, nyob rau hauv thiaj li yuav ua kom tiav cov khoom txhaj tshuaj zoo, the injection pressure and compression ratio must also be considered when selecting the screw. . Feem ntau, a smaller diameter screw provides higher injection pressure.

7. Txhaj ceev ntawm kev txhaj tshuaj molding tshuab:

Confirmation of “txhaj tshuaj ceev”. Some finished products require high injection rate and fast injection to form stably, such as ultra-thin products. Hauv qhov no, it may be necessary to confirm whether the injection rate and injection speed of the machine are sufficient , whether it needs to be equipped with pressure accumulator, closed loop control and other devices. Feem ntau hais lus, nyob rau tib lub sijhawm, cov ntsia hlau uas tuaj yeem muab kev txhaj tshuaj siab dua feem ntau muaj qhov txo qis dua, thiab ntawm qhov tsis sib xws, cov ntsia hlau uas tuaj yeem muab kev txhaj tshuaj qis dua feem ntau muaj qhov kev txhaj tshuaj ntau dua.

Yog li ntawd, thaum xaiv txoj kab uas hla ntawm cov ntsia hlau, qhov ntim tshuaj, txhaj tshuaj siab thiab txhaj tshuaj (txhaj tshuaj ceev) yuav tsum tau txiav txim siab thiab pauv tawm. Ntxiv thiab, multi-loop tsim kuj siv tau los ua kom luv lub sij hawm molding nrog synchronous compound ua.
