[0031] The working principle and use process of the utility model are as follows: when demoulding, the electric push rod 4 is started, and the electric push rod 4 drives the slide plate 5 to move upward along the slide rod 2, thereby driving the upper mold 6 to move upward and separate from the lower mold 7. When the slide plate 5 moves upward and contacts the limit top block 13, the slide plate 5 continues to move upward, driving the limit top block 13 to move upward, thereby driving the first push rod 12 to move upward, and then driving the first piston 11 to move upward. The first piston 11 pushes the second piston 15 to move upward, thereby driving the second push rod 16 to move upward, and then driving the lower push block 17 to move upward. If the workpiece is stuck Attached to the lower mold 7, the workpiece is ejected from the lower mold 7 by the upward movement of the lower ejector block 17. When the slide plate 5 moves upward, it drives the third ejector rod 18 to move upward.
