Claims

1. A synchronous mold opening device for a fan blade slider, characterized by: The device includes a fan blade mold opening mechanism and at least one drive mechanism meshing with the fan blade mold opening mechanism. The fan blade mold opening mechanism includes a gear meshing with the drive mechanism, a sliding plate disposed on the gear, a fan blade assembly with its lower part sliding on the gear and its upper part sliding within the sliding plate, at least one limiting plate disposed on the sliding plate, and a slider whose lower end is pushed by the fan blade assembly and passes through the limiting plate to eject the injection molded part. The gear has several fan blade drive grooves evenly arranged on it. The sliding plate has several guide rails arranged sequentially from the center outwards in a radiating pattern. The fan blade assembly includes a rotating wheel sliding within the fan blade drive grooves, several fan blades disposed on the sliding plate arranged sequentially from the center outwards in a radiating pattern, and a linkage shaft with one end disposed at the tail end of the fan blade and the other end passing through the rotating wheel.

2. The leaf slider synchronous mold opening device according to claim 1, characterized in that: The fan blade drives the groove to extend at an angle from the inside to the outside.

3. The leaf slider synchronous mold opening device according to claim 1, characterized in that: The fan blade includes a blade body whose tail end is penetrated by the linkage shaft and slides entirely on the guide rail, an upper plate formed on the right side of the front end of the blade body, a lower plate formed on the left side of the front end of the blade body, and a plate insertion groove formed below the upper plate and matching the lower plate. The lower plate of one fan blade is embedded in the plate insertion groove of the adjacent right fan blade. Multiple fan blades cooperate with each other to form a fan-shaped structure.

4. The vane slider synchronous mold opening device according to claim 3, characterized in that: The upper end of the lower panel has a first embedded inclined guide surface that extends obliquely from the upper left side of the upper panel to the lower left side outward. The lower end surface of the upper panel has a second embedded inclined guide surface that extends obliquely from the lower inside to the upper outside and matches the first embedded inclined guide surface.

5. The leaf slider synchronous mold opening device according to claim 3, characterized in that: A limiting insert block protruding to the left is formed on the right side of the upper panel, and a limiting insert groove matching the limiting insert block is formed at the position where the left side of the upper panel connects with the lower panel.

6. The leaf slider synchronous mold opening device according to claim 3, characterized in that: A first ejection inclined guide surface is formed on the upper end surface of the tail of the leaf body, extending obliquely from the upper part of the leaf body to the lower and outer part.

7. The leaf slider synchronous mold opening device according to claim 6, characterized in that: The slider is generally square prism-shaped, and a second ejection inclined guide surface is formed at the lower part of the end facing the fan blade, which extends inclinedly from the upper outside to the lower inside and matches the first ejection inclined guide surface.

8. The fan blade slider synchronous mold opening device according to claim 7, characterized in that: The slider has chamfered edges that extend vertically downwards at each of its four corners.

9. The leaf slider synchronous mold opening device according to claim 1, characterized in that: The drive mechanism includes a drive motor and a rack mounted on the output shaft of the drive motor and whose front end meshes with the gear.

10. The leaf slider synchronous mold opening device according to claim 1, characterized in that: The number of sliders and fan blades is 13 sets each, and the number of drive mechanisms is 2 sets.
