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.开模行程设定不合理,缓冲速度压力太大,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.開模油缸有空气也會有此現象。

2. This phenomenon also occurs when there is air in the mold opening cylinder.

3.应该是在顶出时慢慢爬行20mm吧,如果是这样就检查合模阀。

3. Crawl slowly for 20mm during ejection. If so, check the clamping valve.

4.先查换向阀中位情形及油缸密封件.还有压力的斜率

4. Check the center position of the reversing valve and the sealing parts of the oil cylinder first And the slope of pressure

5.通过沉头螺丝调节开合调节开合模换向阀内部导引油小孔子(X、Y)可缓解
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.还有可能是油箱空气滤芯堵塞排气不畅!

6. It is also possible that the air filter element of the oil tank is blocked and the exhaust is not smooth!

7.开锁模油缸内泄.检查活塞密封圈和活塞与活塞杆之间螺纹内泄。

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.
