[0002] In the production process of photovoltaic panels, injection molding is one of the important manufacturing processes. After injection molding, in order to remove the molded photovoltaic panel from the mold, an ejection mechanism is usually required. Demolding is an indispensable step. Usually, an ejection mechanism is used to eject the molded photovoltaic panel from the mold.

[0003] Traditional ejector mechanisms generally use a single ejector device, relying on a fixed ejector pin or ejector rod to eject the product. This design may result in uneven ejection or incomplete demolding when processing photovoltaic panels with complex shapes, diverse sizes, or special materials. This can lead to quality problems such as scratches and deformation on the surface of the finished product, and even affect the photoelectric performance of the photovoltaic panel. To this end, we have designed an ejector mechanism for photovoltaic panel injection molding demolding equipment to provide an alternative technical solution to the above technical problems.

[0022] A rectangular through-groove is provided inside the injection bottom mold 1, and the bottom embedded plate 2 is located inside the rectangular through-groove and is slidably connected to the injection bottom mold 1 through the rectangular through-groove, thereby enabling the bottom embedded plate 2 to be located inside the injection bottom mold 1 and to slide vertically inside the injection bottom mold 1;

[0023] The lifting assembly includes a vertical slide tube 5, both ends of the bottom of the bottom embedded plate 2 are fixed with a vertical slide tube 5, the vertical slide tube 5 is slidably connected to a vertical polished rod 6 inside, one end of the vertical slide tube 5 is rotatably connected to an oblique rotating column 7 through a pin, and one end of the oblique rotating column 7 is provided with a transverse connecting rod 8. Arc-shaped fixed columns 10 are fixed on both sides of the inside of the injection bottom mold 1, and a first hydraulic lever 9 is fixed inside the arc-shaped fixed column 10. The output end of the first hydraulic lever 9 is connected to the transverse connecting rod 8;

[0024] A vertical through hole is provided inside the vertical slide tube 5. The vertical polished rod 6 is located inside the vertical through hole and is slidably connected to the vertical slide tube 5 through the vertical through hole. The vertical through hole allows the vertical slide tube 5 to slide vertically on the outside of the vertical polished rod 6.

[0025] Here, the operation of the first hydraulic lever 9 enables the transverse connecting rod 8 to move. The movement of the transverse connecting rod 8 enables the vertical slide tube 5 to slide vertically outside the vertical polished rod 6 through the oblique rotating column 7, thereby enabling the bottom embedded plate 2 to be vertically raised and lowered inside the injection bottom mold 1.

[0026] The transverse movement assembly includes an L-shaped moving frame 4, the L-shaped moving frame 4 is fixed to the bottom of the vertical polished rod 6, a circular limit ring 13 is fixed to the outside of the output end of the first hydraulic lever 9 and close to the end of the transverse connecting rod 8, the inside of the L-shaped moving frame 4 is slidably connected to the transverse polished rod 11, and circular limit blocks 15 are fixed at both ends of the transverse polished rod 11. An arc-shaped fixing plate 12 is fixed to the outside of the middle position of the transverse polished rod 11, and the top of the arc-shaped fixing plate 12 is fixedly connected to the injection bottom mold 1. A transverse rigid spring 14 is provided between the L-shaped moving frame 4 and the arc-shaped fixing plate 12 and located on the outside of the transverse polished rod 11;

[0027] The first hydraulic lever 9 passes through the interior of the L-shaped movable frame 4 and is slidably connected to the L-shaped movable frame 4. A transverse through hole is provided inside the L-shaped movable frame 4. The transverse light rod 11 is located inside the transverse through hole and is slidably connected to the L-shaped movable frame 4 through the transverse through hole. Through the setting of the transverse through hole, the L-shaped movable frame 4 can slide laterally on the outside of the transverse light rod 11.

[0028] Here, the operation of the first hydraulic lever 9 enables the circular limiting ring 13 to move. When the circular limiting ring 13 moves toward the L-shaped movable frame 4, and when the circular limiting ring 13 is in contact with the L-shaped movable frame 4, the circular limiting ring 13 can push the L-shaped movable frame 4 to move. The movement of the L-shaped movable frame 4 enables the bottom embedded plate 2 to move laterally inside the injection bottom mold 1.

[0029] Working principle: The operation of the first hydraulic lever 9 enables the transverse connecting rod 8 to move. The movement of the transverse connecting rod 8 enables the vertical slide tube 5 to slide vertically on the outside of the vertical polished rod 6 through the oblique rotating column 7, thereby enabling the bottom embedded plate 2 to be vertically raised and lowered inside the injection bottom mold 1. When the bottom embedded plate 2 rises, the material can be lifted up. When the bottom embedded plate 2 falls, the bottom embedded plate 2 can move into the injection bottom mold 1.

[0030] Then, the continuous operation of the first hydraulic lever 9 enables the circular limiting ring 13 to move. When the circular limiting ring 13 moves toward the L-shaped movable frame 4 and fits with the L-shaped movable frame 4, the circular limiting ring 13 can push the L-shaped movable frame 4 to move. The movement of the L-shaped movable frame 4 enables the bottom embedded plate 2 to move laterally inside the injection bottom mold 1.

[0031] At this time, the operation of the second hydraulic cylinder 16 can lift the top plate 3, so that the top plate 3 can pass through the rectangular through groove of the injection bottom mold 1 and lift the material.
