在注塑加工中有時(shí)模具開(kāi)到底后還會(huì )彈回20mm左右，這里濟南注塑加工廠(chǎng)就來(lái)說(shuō)說(shuō)注塑模具回彈是怎么回事?
In injection molding, sometimes the mold will bounce back about 20mm after it is opened to the end. Here, Jinan injection molding factory will talk about the rebound of injection mold?
1.開(kāi)模行程設定不合理,緩沖速度壓力太大,位置太小。
1. The setting of mold opening stroke is unreasonable, the buffer speed pressure is too large, and the position is too small.
2.開(kāi)模油缸有空氣也會(huì )有此現象。
2. This phenomenon also occurs when there is air in the mold opening cylinder.
3.應該是在頂出時(shí)慢慢爬行20mm吧,如果是這樣就檢查合模閥。
3. Crawl slowly for 20mm during ejection. If so, check the clamping valve.
4.先查換向閥中位情形及油缸密封件.還有壓力的斜率
4. Check the center position of the reversing valve and the sealing parts of the oil cylinder first And the slope of pressure
5.通過(guò)沉頭螺絲調節開(kāi)合調節開(kāi)合模換向閥內部導引油小孔子(X、Y)可緩解
5. Adjust the opening and closing by countersunk screws. The small Confucius (x, y) in the opening and closing die reversing valve can be relieved
6.還有可能是油箱空氣濾芯堵塞排氣不暢!
6. It is also possible that the air filter element of the oil tank is blocked and the exhaust is not smooth!
7.開(kāi)鎖模油缸內泄.檢查活塞密封圈和活塞與活塞桿之間螺紋內泄。
7. Internal leakage of unlocking die cylinder Check the internal leakage of the piston sealing ring and the thread between the piston and the piston rod.
