In the present embodiment, the distance between the first connection end and the rotation shaft 910 is greater than the distance between the second connection end and the rotation shaft 910. When the striker 700 drives the second connecting end to move downward by a smaller distance, the first connecting end can move upward by a larger distance, which is more beneficial to the secondary ejection and shortens the stroke of the top roller of the injection molding machine. Moreover, since the distance of the downward movement of the second connecting end is smaller, the height of the movable groove 431 can be relatively smaller, so that the structure of the whole mold secondary ejection device is more compact.

In addition, the embodiment of the utility model also provides a die structure, which comprises the die secondary ejection device provided in any embodiment, can assist in injection molding of injection products, can realize demolding action of the injection products, and has the advantages of high demolding success rate, reasonable structural design, proper size, convenient installation and lower manufacturing cost.
