When it moves to a certain extent, the inner wall of the fixed mold 10 can cause the rotating block 13 to rotate so that the other end of the rotating block 13 pushes the sliding plate 14 to slide a certain position. The position change of the sliding plate 14 can enable the multiple fixed columns 15 to move and push the product. Adding a secondary ejection structure can eject again on the basis of one ejection, making the demoulding of the vacuum cleaner shell smoother, effectively avoiding product sticking to the mold and straining, ensuring the appearance is complete and flawless, improving production efficiency, reducing the time for manual processing of defective products, improving the yield rate, and reducing waste loss.
