[0022] One side of the clamp 6 is rotatably connected to a connecting rod 3 9, and one side of the clamp 6 is fixedly connected to two pairs of slide rails 3 10, each pair of slide rails 3 10 is slidably connected to a connecting rod 4 11, and one side of each connecting rod 4 11 is fixedly connected to a pair of clamping rods 12, and one end of each connecting rod 4 11 is rotatably connected to the connecting rod 3 9 through a connecting rod 5 13, and one end of a connecting rod 4 11 is fixedly connected to a cylinder 2 14, which is fixedly connected to the clamp 6, and the contraction of the cylinder 2 14 can pull The movable connecting rod 4 11 moves along the slide rail 3 10 toward the middle of the clamp 6. At the same time, the movement of the connecting rod 4 11 drives one end of the connecting rod 3 9 to rotate counterclockwise through the connecting rod 5 13. Since the connecting rod 3 9 is an equal-arm lever, the other end of the connecting rod 3 9 also rotates counterclockwise, pulling the other connecting rod 4 11 synchronously toward the middle of the clamp 6. The two pairs of clamping rods 12 fixedly connected to the connecting rod 4 11 approach each other to clamp the plastic lunch box. Similarly, the extension of the cylinder 2 14 can release the plastic lunch box.

One end of the ejector rod is fixedly connected to a T-shaped connecting block, and the plastic lunch box can be cooled and solidified through the cooling pipe. The servo motor 2 15 can drive the lead screw to rotate so that the lead screw nut threadedly connected thereto moves toward the servo motor 2 15, thereby causing the H-shaped connecting block, the connecting rod 6 and the punch 16 to move synchronously. When one end of the T-shaped connecting block reaches the outer wall of the machine body 1, the two ejector rods fixedly connected to the other end of the T-shaped connecting block slide toward the clamp 6 to eject the plastic lunch box;

The melt is then injected into a closed mold with a lower temperature.

[0026] The first body 1 and the second body 2 are fixedly connected via a connecting seat.

[0027] The functional principle of this utility model can be explained through the following operation modes:

[0028] The plastic particles enter the melting barrel 18, and the plastic is gradually melted into a uniform melt through the internal heating of the melting barrel 18. The melt is then injected into the closed mold with a lower temperature. The plastic lunch box can be cooled and solidified through the cooling pipes on both sides of the punch 16. The servo motor 2 15 can drive the lead screw to rotate, so that the lead screw nut threadedly connected to it moves toward the servo motor 2 15, thereby causing the H-shaped connecting block, connecting rod 6 and punch 16 to move synchronously. When one end of the T-shaped connecting block moves to the outer wall of the body 1, the two ejector rods fixedly connected to the other end of the T-shaped connecting block slide toward the clamp 6 to eject the plastic lunch box;

[0029] When the plastic lunch box is ejected, the clamp 6 moves to the punch 16 and gradually clamps the plastic lunch box. The contraction of the cylinder 2 14 can pull the connecting rod 4 11 along the slide rail 3 10 to the middle of the clamp 6. At the same time, the connecting rod 4 11 can drive one end of the connecting rod 3 9 to rotate counterclockwise through the connecting rod 5 13. Since the connecting rod 3 9 is an equal-arm lever, the other end of the connecting rod 3 9 also rotates counterclockwise, pulling the other connecting rod 4 11 to move synchronously to the middle of the clamp 6, and the two pairs of clamping rods 12 fixedly connected to the connecting rod 4 11 are rotated. The plastic lunch box is clamped close to each other, and then the servo motor 4 rotates to drive the slide rail 5 and the clamp 6 to move in a circle through the connecting rod 1, and the plastic lunch box is moved to the side of the plastic lunch box injection molding device. At the same time, the contraction of the cylinder 17 allows the clamp 6 to rotate to a horizontal position with the rotation connection between the slide rail 5 and the clamp 6 as the center. Finally, the cylinder 2 14 of the clamp 6 extends to release the plastic lunch box, so that the plastic lunch box is neatly stacked with the opening facing downward, which speeds up production efficiency and avoids the health and safety hazards that may be caused by manual stacking.
