AI Technical Summary
Technical Problem
In existing secondary ejection mold structures, the movement of the ejector plate insert is unstable and prone to jamming, which prevents the product from separating smoothly and affects production efficiency.
Method used
A spring and an ejector plate insert are installed between the ejector plate and the face plate. The spring force keeps the ejector plate insert moving smoothly during the ejection process, preventing jamming. Combined with the lubricating oil groove, friction is reduced and stability is ensured.
Benefits of technology
This achieves stable movement of the ejector plate insert, ensuring the smooth completion of the secondary ejection action and improving the stability and production efficiency of the mold under long-term ejection motion.

Abstract
本发明属于注塑模具设备领域，具体公开了一种二次顶出装置和具有其的二次顶出模具结构，二次顶出装置包括动模底板以及设于动模底板上方的顶针板、面针板和顶针板镶件，面针板设于顶针板的上端并与顶针板贴合连接，顶针板镶件竖向滑动设于顶针板和面针板之间，顶针板镶件的下端伸出于顶针板外，面针板与顶针板镶件之间抵持有弹簧；通过弹簧的复位作用，能够防止顶针板镶件卡死在顶针板上，使得顶针板镶件能够在顶出运动的过程中的移动更流畅，能够完成二次顶出的动作，保证整个装置在长时间的顶出运动下仍然具有较好的稳定性。
