[0002] In recent years, the technology of vertical injection molding machines for plush toy eyes has been widely applied and rapidly developed in the toy manufacturing industry. This technology is mainly used to produce the eyes of plush toys. The eyes consist of two parts: the pupil part and the sclera part. The pupil part is usually pre-made and then placed in the mold, while the injection molding machine is responsible for injecting the sclera part onto the pupil. Through this process, high precision and high consistency of the eyes can be achieved, ensuring the appearance quality of plush toys. With the improvement of automation and intelligent technologies, the efficiency and stability of vertical injection molding machines have been continuously enhanced.

[0003] During the production process of plush toy eyes, general vertical injection molding machines face some disadvantages in use, especially the positioning problem of the pupil part. Due to vibration or improper manual placement, the pupil part may be skewed during the injection process, resulting in unqualified plush toy eyes after injection. This skew not only affects the appearance of the product, making the eyes asymmetrical and reducing the overall aesthetic feeling, but also may cause quality complaints from consumers, affecting the brand image. The low qualified rate will increase production costs and time, and at the same time bring economic losses, unable to meet the actual needs. Summary of the Invention

An auxiliary hole is arranged at the top edge of the piston 49. A sliding cylinder is arranged at the top of the auxiliary. The sliding cylinder is communicated with the plurality of exhaust holes 36, connecting the movement cavity 47 and the bottom space of the movement cavity 47. The bottom space of the movement cavity 47 is used for the sliding of the sliding block 43.

[0034] Further, a ventilation hole 41 is arranged inside the movement seat 9 near the second spring 42. A first ventilation pipe 39 and a second ventilation pipe 40 are respectively arranged on one side of the air pump 13. One end of the second ventilation pipe 40 is connected inside the second middle hole 38. One end of the first ventilation pipe 39 is connected inside the first middle hole 37. The second ventilation pipe 40 is used for inhaling air, and the first ventilation pipe 39 is used for exhausting air. A through hole is arranged inside the movement seat 9. The through hole is connected with the air guide pipe 29. The through hole, the second middle hole 38 and the bottom hole 48 are at the same height.

[0035] In this embodiment, by starting the air pump 13, a negative pressure is formed inside the plurality of air outlet pipes on the rotating frame 22 through the second ventilation pipe 40, the second middle hole 38, the bottom hole 48, the through hole and the air guide pipe 29. Exhaust air through the first ventilation pipe 39, the first middle hole 37, the top hole 51, the first side hole, the air guide channel 52 and the air outlet pipe.

Adsorb the pupil pieces 31 on the air outlet pipe through negative pressure. Start the control drive motor 3 to drive the threaded rod 2 to rotate, so that the movement seat 9 and the lower mold 6 stop at the designated positions. Manually flip the rotating frame 22 through the handle 24, so that the rotating frame 22 drives the plurality of pupil pieces 31 to press on the upper surface of the lower mold 6, and put the plurality of pupil pieces 31 into the injection molding groove 33.

[0037] What needs to be further explained is that the negative pressure of the air outlet pipe disappears, and at the same time, negative pressure is generated at the bottom of the injection molding groove 33. The pupil piece 31 falls into the interior of the injection molding groove 33. By squeezing the piston 49, the suction cup 46 is adsorbed on the bottom of the movement cavity 47. Manually rotate the rotating frame 22 to make the rotating frame 22 return to its original position, and the extrusion rod 35 remains in its original position. Control the driving motor 3 to drive the threaded rod 2 to rotate, thereby driving the movement seat 9 and the lower mold 6 to move to the bottom of the upper mold 5. The air guide pipe 29 is long enough to enable the lower mold 6 to move to the bottom of the upper mold 5. Start the injection molding machine 4, and inject the molten plastic into the interiors of the multiple injection molding grooves 33 through the injection molding channels. The pupil piece 31 is stably adsorbed in the interior of the injection molding groove 33 by the negative pressure inside the injection molding groove 33, preventing the molten plastic from squeezing the pupil piece 31 during the injection molding process and causing the pupil piece 31 to deviate from its original position, achieving the effects of cleaning the injection molding groove 33 and preventing the pupil piece 31 from deviating during the injection molding process.

[0038] Refer to Figure 1 、 Figure 5 、 Figure 6 and Figure 8 In a preferred embodiment, the linkage mechanism includes a rack 28 fixedly connected to the other side of the movement seat 9. A gear 27 is rotatably connected to the upper surface of the mounting plate 8 near the rack 28. A second pulley 32 is fixedly connected to one side of the gear 27.

[0039] The magnetic attraction mechanism includes a support frame 19 fixedly connected to the top of the fixed plate 16. A plurality of thin plates are provided on the support frame 19, and a plurality of rotating blocks 30 are respectively rotatably connected to the sides of the thin plates.

[0040] One side of the rotating block 30 is provided with, and every two rotating blocks 30 cooperate to form a space for placing the injection molding groove 33 between the two rotating blocks 30.

[0041] The bottoms of the rotating blocks 30 are respectively fixedly connected with, the material of the air outlet pipe is iron, and a material guiding plate 20 is fixedly connected to the bottom of the support frame 19.

[0042] One end of the material box 7 is provided with a discharge plate 17, and a first stop block 18 and a second stop block 23 are respectively provided on one side of the fixed plate 16.

[0043] In this embodiment, after the air pump 13 is turned off, the upper mold 5 and the lower mold 6 are separated, and the injection-molded toy eyes are taken out. The driving motor 3 is controlled to drive the threaded rod 2 to rotate, so as to drive the moving seat 9 and the lower mold 6 to move to the position of the second baffle 15. During the movement of the moving seat 9 and the lower mold 6, the rack 28 drives the gear 27 to rotate, so that the second pulley 32 and the belt 25 drive the first pulley 26 and the material box 7 to rotate. One end of the material box 7 with the discharge plate 17 is heavy and the other end is light. A large number of pupil pieces 31 are placed inside the material box 7. When one end of the material box 7 with the discharge plate 17 is lifted to the moving height, the second stopper 23 blocks the rotation of the material box 7.

[0044] Further, a large number of pupil pieces 31 slide onto the upper surface of the rotating frame 22 through the discharge plate 17, and the first baffle 14 squeezes the insertion rod 45 and the second spring 42, so that the sliding block 43 slides to a position where the inner hole 44 and the connection hole communicate, and the negative pressure at the bottom of the suction cup 46 disappears. Under the elastic force of the first spring 34, the extrusion rod 35 slides upward, and the negative pressure is re-generated inside the air outlet pipe. At the same time, at the position where a large number of pupil pieces 31 slide, the two rotating blocks 30 rotate relative to each other, and the two rotating blocks 30 clamp the air outlet pipe. At this time, the air outlet pipe is located between the two rotating blocks 30, and the pupil pieces 31 will be adsorbed by the negative pressure of the air outlet pipe, preparing for the next feeding of the pupil pieces 31, achieving the effect of automatic and rapid feeding.

[0045] At the same time, during the process of the material box 7 rotating back, the material box 7 will be blocked by the first stopper 18 and stop rotating. A large number of pupil pieces 31 will fall from above the rotating frame 22 into the interior of the material box 7. Due to the inclination angle of the material box 7, a large number of pupil pieces 31 slide to one end of the material box 7, achieving the effect of recycling the pupil pieces 31.

[0046] Working principle: When in use, start the air pump 13 to form negative pressure inside the multiple air outlet pipes on the rotating frame 22 through the second air pipe 40, the second middle hole 38, the bottom hole 48, the through hole and the air guide pipe 29. Exhaust through the first air pipe 39, the first middle hole 37, the top hole 51, the first side hole, the air guide channel 52 and the air outlet pipe to clean the dust and impurities inside the injection molding groove 33. Put multiple pupil pieces 31 into it, and adsorb the pupil pieces 31 on the air outlet pipe by negative pressure. Start the control drive motor 3 to drive the threaded rod 2 to rotate, so that the moving seat 9 and the lower mold 6 stop at the designated position. Manually turn the rotating frame 22 through the handle 24, so that the rotating frame 22 drives the multiple pupil pieces 31 to press on the upper surface of the lower mold 6, and the multiple pupil pieces 31 are put into the injection molding groove 33. Squeeze the extrusion rod 35 and the first spring 34 through the rotating frame 22, drive the piston 49 to slide downward, so that the top hole 51 and the first side hole are separated, the middle hole 50 is respectively connected to the second side hole and the second middle hole 38, and at the same time the top hole 51 is separated from the first middle hole 37. Exhaust through the first air pipe 39, the first middle hole 37, the auxiliary hole, the sliding cylinder and the exhaust hole 36. The auxiliary hole is connected to the first middle hole 37, so that the negative pressure of the air outlet pipe disappears, and at the same time negative pressure is generated at the bottom of the injection molding groove 33. The pupil piece 31 falls into the injection molding groove 33. By squeezing the piston 49, the suction cup 46 is adsorbed on the bottom of the movement cavity 47. Manually turn the rotating frame 22 to make the rotating frame 22 return to the original position, and the extrusion rod 35 still remains in the original position. Control the drive motor 3 to drive the threaded rod 2 to rotate, so as to drive the moving seat 9 and the lower mold 6 to move to the bottom of the upper mold 5. The air guide pipe 29 is long enough to make the lower mold 6 move to the bottom of the upper mold 5. Start the injection molding machine 4 to inject the molten plastic into the multiple injection molding grooves 33 through the injection channel. The pupil piece 31 is stably adsorbed in the injection molding groove 33 by the negative pressure inside the injection molding groove 33, preventing the molten plastic from squeezing the pupil piece 31 during the injection molding process and causing the pupil piece 31 to deviate from its original position, achieving the effects of cleaning the injection molding groove 33 and preventing the pupil piece 31 from deviating during the injection molding process. After closing the air pump 13, separate the upper mold 5 and the lower mold 6, take out the injection molded toy eyes, control the drive motor 3 to drive the threaded rod 2 to rotate, so as to drive the moving seat 9 and the lower mold 6 to move to the position of the second baffle 15. During the movement of the moving seat 9 and the lower mold 6, drive the gear 27 to rotate through the rack 28, so that the second pulley 32 and the belt 25 drive the first pulley 26 and the material box 7 to rotate. One end of the material box 7 with the discharge plate 17 is heavy and the other end is light. A large number of pupil pieces 31 are placed inside the material box 7. When one end of the material box 7 with the discharge plate 17 is lifted to the moving height, the second stop block 23 blocks the rotation of the material box 7, and a large number of pupil pieces 31 slide to the upper surface of the rotating frame 22 through the discharge plate 17. Squeeze the insertion rod 45 and the second spring 42 through the first baffle 14, so that the sliding block 43 slides to make the inner hole 44 communicate with the connection hole, and the negative pressure at the bottom of the suction cup 46 disappears. Under the elastic force of the first spring 34,Slide the extrusion rod 35 upward to recreate negative pressure inside the air outlet pipe. At the same time, a large number of pupil pieces 31 slide to their positions, driving the two rotating blocks 30 to rotate relative to each other. The two rotating blocks 30 clamp the air outlet pipe. At this time, the air outlet pipe is located between the two rotating blocks 30, and the pupil pieces 31 will be adsorbed by the negative pressure of the air outlet pipe, preparing for the next feeding of the pupil pieces 31, achieving the effect of automatic and rapid feeding. During the process of the material box 7 rotating back, the material box 7 will be blocked by the first stop block 18 and stop rotating.
