Xya ejection mechanisms
1. Push thaiv ejection mechanism
Rau cov khoom yas tiaj tus nrog flanges, yog tias ejection nrog lub laub phaj yuav ua raws li cov pwm, yuav tsum siv lub laub thaiv ejection mechanism. Vim tias lub laub thaiv yog qhov tseem ceeb ntawm cov kab noj hniav, nws yuav tsum muaj zog dua thiab qis dua qhov roughness.
Muaj ob hom kev rov pib dua: ib qho tso siab rau lub siab yas, thiab lwm yam siv lub pas nrig rov pib dua.
ob. Siv cov molded qhov ejection mechanism
Vim yog cov qauv tsim thiab cov yas siv, qee qhov yas tsis tsim nyog siv cov txheej txheem ejection xws li ejector pins, ejector raj, laub daim hlau, thiab thawb blocks. Nyob rau hauv rooj plaub no, molding inserts los yog concave pwm tuaj yeem siv los nqa tawm cov khoom yas. Lub laub thaiv tau hais ua ntej lawm belongs rau txoj kev ntxig ejection mechanism.
peb. Multi-component comprehensive ejection mechanism
Nws yog hais txog kev sib xyaw ua ke ntawm ob peb ejection mechanisms tau hais los saum toj no kom ua tiav lub hom phiaj ntawm ejection. Feem ntau siv xws li ejector pas nrig ntxiv rau sab saum toj phaj, ejector raj ntxiv rau sab saum toj phaj
Plaub. Cua siab khiav mechanism
Kev siv cua siab demoulding yuav tsum tau teeb tsa cov cua compressed thiab li qub. Kev ua haujlwm yog qhov yooj yim thiab tsim nyog rau demoulding lub teeb thiab nyias cov yas mos.
tsib. Inclined slider khiav mechanism
Thaum cov khoom yas muaj qhov sab hauv thiab sab nrauv los yog cov kab hauv qab uas txawv ntawm cov pwm qhib kev taw qhia, uas cuam tshuam qhov ncaj qha demoulding ntawm cov yas, yuav tsum tau siv cov txheej txheem inclined slider demoulding. Qhov chaw nrog sab qhov los yog undercuts yog ua rau hauv cov cores txav tau. Thaum cov yas yog demoulded, cov tub ntxhais txav tau yog thawj rub tawm, thiab tom qab ntawd cov yas yog ejected los ntawm pwm. Lub tshuab ua kom tiav qhov kev rho tawm thiab rov pib dua ntawm cov tub ntxhais txav tau hu ua core-rub mechanism.
6. Khoov tus pin parting thiab core rub mechanism
Nws lub hauv paus ntsiab lus yog tib yam li cov lus qhia inclined post core-rub mechanism, tab sis qhov txawv yog tias inclined qhia ncej yog hloov los ntawm ib tug bent pin nrog ib tug duab plaub cross-section. Nws qhov zoo dua yog tias lub kaum sab xis bevel tuaj yeem ua kom loj dua.
7. Inclined qhia groove parting thiab core rub mechanism
<1>﹑ Tsim qauv ntawm txoj kab nqes thiab kev txiav txim siab ntawm ntau qhov ntev:
1. Txiav txim siab cov tub ntxhais rub tawm qhov deb raws li cov duab ntawm cov khoom: S kos duab=S undercut + (2 ~ 3) mm.
2. Raws li qhov ejection stroke, xam lub kaum sab xis ntawm lub ru tsev inclined (tg=S pumping / S lifting). Tus nqi yuav tsum tsis txhob loj dhau. Yog tias nws loj heev, lub zog khoov ntawm lub ru tsev inclined yuav loj, uas yuav yooj yim ua rau tawg. Feem ntau, nws yog 3 Less tshaj los yog sib npaug rau Less tshaj los yog sib npaug rau 8˚.
3. Paub meej tias txoj hauj lwm ntawm qhov taw qhia P ntawm lub ru tsev inclined nyob rau hauv pwm yog tus lej.
4. Paub meej tias lub thickness L1 ntawm lub ru tsev sloped. L1 tau txiav txim siab raws li qhov xwm txheej tiag tiag, tab sis tus nqi no yuav tsum tsis txhob tsawg dhau, txwv tsis pub lub zog ntawm lub ru tsev sloped tsis tuaj yeem lav.
5. Qhov kev ncua deb H ntawm lub inclined sab saum toj thiab cov pwm core yog feem ntau 5 ~ 10mm (nyob ntawm seb lub thickness ntawm cov pwm core).
<2>Cov teeb meem yuav tsum nco ntsoov thaum tus txheej txheem tsim:
1. Lub ru tsev inclined tsis tuaj yeem ua rau lwm qhov ntawm cov khoom puas thaum ejecting cov khoom.
2. Lub qhov nyob hauv lub cev phaj ntawm lub ru tsev inclined yuav tsum muaj peev xwm ua kom haum rau lub ru tsev inclined.
3. Determine the size and direction of the sliding groove of the inclined top seat on the upper ejection plate. To make the inclined roof work smoothly, that is, to ensure smooth movement of the inclined roof on the upper ejection plate and sufficient space for movement, so we It is necessary to make sure that the space in the direction of movement of the inclined top seat is large, and ensure that L2>S yog kos.

1. Kev faib pwm yooj yim (Daim duab 1 thiab daim duab 2)
2.R kaum kev ua haujlwm (Daim duab 3)
3. Kev cuam tshuam 1: Chaw mus ncig tsis txaus (raws li pom hauv daim duab 4)
Kev daws: (1) Txav lossis txiav cov khoom tiav; (Cov neeg siv khoom pom zoo) raws li qhia hauv daim duab 5
(2) Txo cov thickness ntawm lub ru tsev sloped; (kom muaj zog)
duab
(3) Hloov cov kev taw qhia ntawm cov tub ntxhais rub; (lengthen lub stroke) raws li qhia hauv daim duab 6
4. Kev cuam tshuam 2: Raws li cov kev taw qhia ntawm cov tub ntxhais rub tawm, cov khoom tiav lawm muaj qhov qis qis, thiab sab saum toj inclined tsis tuaj yeem thim rov qab.
Kev daws: (1) Txo cov kua nplaum hauv cov khoom tiav (pom zoo rau cov neeg siv khoom) raws li qhia hauv daim duab 7
duab
(2) Ua ib txoj kab nqes b nyob rau hauv qab ntawm lub hauv paus inclined ru tsev kom ncua lub ejection ntawm lub ru tsev inclined, raws li qhia hauv daim duab 8
Yuav tsum muaj: ﹕ｽb Ntau dua lossis sib npaug rau ｽa˚ ｽc Ntau dua lossis sib npaug rau ｽb˚
5. Lub demoulding lub kaum sab xis yog ntau dua los yog sib npaug rau 2. Vim lub me me rub quab yuam ntawm inclined sab saum toj, demoulding yog qhov nyuaj.
<4>﹑ Lub ru tsev inclined yog txuam nrog cov txiv neej pwm core
duab
1. Kev sib txuam yooj yim (raws li qhia hauv daim duab 9), cov txiv neej pwm core kab yog txiav nrog oblique qhov.
2. Ntxiv kev taw qhia (Daim duab 10).
Thaum lub inclined sab saum toj yog dav los yog txoj kab nqes ntawm cov pwm core (qhia) luv luv, lub inclined sab saum toj yuav qaij mus rau cov khoom tiav thaum ejection, shortening tus tsim stroke thiab ua demoulding nyuaj. Cov lus qhia yuav tsum tau ntxiv, nyob rau hauv daim ntawv ntawm:
a. Ntxiv ib qho T-zoo li tus nuv ntawm ib sab (ib leeg);
b. Ntxiv ib tug nuv los yog dovetail zawj rau tom qab;
3. Pwm core insert (Daim duab 11)
When the male mold core is too thick (such as >150mm), qhov tseeb ntawm cov hlau txiav (kab dabtsi yog khoov) yuav raug txo, lub sijhawm ua haujlwm yuav ntev, thiab lub qhov threading yuav nyuaj rau kev xyaum. Inserts yuav tsum xav txog.

<5>﹑ Txiv neej qauv nyiag qhov
Cov ntsiab lus tseem ceeb: a. Ua ntej tho qhov puag ncig, tom qab ntawd lub qhov square, tom qab ntawd qhov tshwj xeeb-puab qhov;
b.1KP nyiag lub qhov loj thiab qhov chaw raug tshuaj xyuas los ntawm ob ntu ntu
(Raws li pom hauv daim duab 12);
c. Kev nyiag qhov yuav tsum tau kos rau ntawm lub dav hlau sib dhos rau kev tshuaj xyuas
Nws puas cuam tshuam nrog cov nplhaib sib khi, cov kav dej, thimbles, screws, thiab lwm yam?
d. Qhov chaw thiab qhov loj ntawm qhov raug nyiag lawm yuav raug muab sib dhos ua ntej.
<6>﹑ Kev sib txuas ntawm lub ru tsev inclined thiab ejection phaj
Kev sib txuas 1: Lub ru tsev inclined thiab lub hauv paus ru tsev yog txuas nrog T-zoo li tus nuv (Daim duab 13).
Yog hais tias lub thickness ntawm lub ru tsev inclined me dhau, siv ib tug sib sib zog nqus nuv; lub phaj hnav-resistant yuav tsum tau ntxiv rau hauv qab ntawm tus txiv neej pwm; kev hloov kho yog qhov nyuaj, yog li koj tuaj yeem ua tau
Khaws 1 ~ 2mm nyob rau hauv qab ntawm lub hauv paus saum toj kawg nkaus rau kev hloov kho thaum sib dhos.
Kev sib txuas 2: Lub ru tsev inclined dome txuas nrog lub hauv paus ru tsev inclined, thiab tus so yog tib yam li ua ntej (Daim duab 14).
Kev sib txuas 3: Lub ru tsev inclined yog lengthened thiab lub ru tsev inclined yog luv (los txhim kho qhov tawv). Tus txiv neej pwm tsis tas yuav ntxiv cov phaj hnav-tiv taus (raws li qhia hauv daim duab 15).
