[0030] Solution Analysis: I. Solving the ejection force problem, significantly improving the precision and yield of gear injection molded parts. Existing devices suffer from poor ejection structure design, resulting in concentrated force on the gear during ejection, which easily leads to deformation and cracking. This innovative solution employs a "suction cup adsorption + hydraulic cylinder pull-out" method: when the central hydraulic cylinder 14 lifts, the suction cup 16 first presses against the center of the gear injection molded part. After the vacuum pump 18 is activated, the suction cup 16 uses negative pressure to evenly adsorb the gear surface, and then the hydraulic cylinder 14 retracts to remove the part. This design ensures that the extraction force is evenly applied to the central area of ​​the gear, avoiding excessive localized force and fundamentally reducing the risk of gear deformation and cracking. Simultaneously, the cooling lower mold 29 precisely shapes the injection molded part, further ensuring gear profile accuracy and product consistency, significantly improving the yield rate.

[0031] II. Optimize the pickup and processing flow to significantly improve production efficiency. The inefficient ejection structure, resulting in "long ejection time and slow mold separation," is the efficiency bottleneck of existing equipment. This solution accelerates the process through multi-mechanism collaboration: On the one hand, the part removal process does not rely on complex structures such as traditional ejector pins. The combination of suction cup adsorption and hydraulic cylinder retraction is simple and efficient, which can quickly separate the gear from the cooling lower mold 29, shortening the single part removal time. On the other hand, the equipment uses an automated process of "four-corner hydraulic cylinder positioning - flipping plate flipping - part removal - reset." During injection and cooling, the four-corner hydraulic cylinders 14 are inserted into the bottom slots 212 to ensure stability. When removing the part, it is only necessary to retract the hydraulic cylinders 14 at the four corners, flip the plate 180 degrees, and then insert the hydraulic cylinders 14 at the four corners for positioning. The whole process does not require much manual intervention, and the actions of each mechanism are uniformly controlled by an external control unit. The timing is closely connected, which greatly reduces the process gap and realizes the rapid batch molding of gear injection molded parts.

[0032] III. Multi-dimensional structural positioning design ensures the stability of device operation. The entire process of the device, from "injection molding" to "part removal," is enhanced with precise structural positioning to improve stability: During the injection and cooling stages, the output ends of the hydraulic cylinders 14 at the four corners are inserted into the slots 212 at the bottom of the flip plate 25 to provide stable support for the cooling lower mold 29, preventing mold displacement during high injection pressure or cooling; During part removal, the flip plate 25, through the cooperation of the first rotating shaft 26, the second rotating shaft 28, and the bearings 23 and 24 of the fixed plate 21, achieves a precise 180-degree flip driven by the stepper motor 27. After flipping, the hydraulic cylinders 14 at the four corners are inserted back into the corresponding slots 212 to provide a stable reference for the part removal process, preventing mold shaking during part removal from causing adsorption displacement; In addition, the cooperation between the lifting groove 32 and the guide column 34 of the lifting plate 31 in the guide mechanism 3 and the limiting block 46 in the injection mechanism 4 ensures that when the cylinder 43 drives the upper mold 47 to descend, it accurately connects with the cooling lower mold 29, avoiding mold closing deviations that affect sealing and injection quality.

[0033] IV. Balancing sealing performance and operational flexibility In terms of sealing and structural adaptability, this design also has advantages: the sealing plate 48 at the bottom of the upper mold 47 and the sealing area 211 of the cooling lower mold 29 are precisely matched, and after the mold is closed, the edge of the upper mold 47 and the edge of the cooling lower mold 29 are connected to form a double sealing structure, which effectively prevents the leakage of molten raw materials and ensures the stability of the injection molding process.

[0034] Working principle: Hydraulic cylinder 14, vacuum pump 18, stepper motor 27, and pneumatic cylinder 43 are all controlled by an external controller. Pneumatic cylinder 43 lowers the lifting plate 45, causing the sealing plate 48 of the upper mold 47 to fit into the sealing area 211 of the cooling lower mold 29. At this time, the edge of the upper mold 47 and the edge of the cooling lower mold 29 are in contact, further sealing the area. After sequential injection molding, the cooling lower mold 29 is cooled internally using existing methods. Once the internal gear injection molded part has cooled and formed, pneumatic cylinder 43 drives the lifting plate 45 to move upwards. During injection molding and cooling, the output ends of the hydraulic cylinders 14 at the four corners are located in the slots 212 at the bottom to provide stability for injection molding, while the hydraulic cylinder 14 in the middle is in a retracted, ready-to-use state. After the lifting plate 45 has moved upwards, the hydraulic cylinders 14 at the four corners retract and disengage from the slots 212 at the bottom. Then, the stepper motor 27 drives the tilting plate 25 to rotate 180 degrees via the rotating shaft 26, so that the cooling template 29 faces downwards. Next, the hydraulic cylinders 14 at the four corners continue to lift and insert into the corresponding slots 212 to provide stability for part removal. When the middle hydraulic cylinder 14 lifts, the suction cup 16 presses against the center of the gear injection molded part. Then, the vacuum pump 18 is activated to evacuate the air from the suction cup 16, causing it to tightly adhere to the gear injection molded part. Afterwards, the middle hydraulic cylinder 14 retracts, pulling out the gear injection molded part for removal. After removal, the hydraulic cylinders 14 at the four corners retract, and the stepper motor 27 flips the tilting plate 25 back, allowing the hydraulic cylinders 14 at the four corners to re-insert into the slots 212 for the next process.

[0035] Technical effects of implementing this solution: This solution, through a combination of innovative features including "uniform adsorption and part removal," "efficient process integration," "multi-dimensional positioning," and "operational stability," not only addresses the core pain points of existing devices such as "ejection deformation and cracking" and "low production efficiency," but also further enhances the practicality of the device in terms of sealing stability and operational flexibility. Ultimately, it achieves a comprehensive effect of "high-precision molding, high-efficiency production, and high-stability operation" for gear injection molded parts, providing a better equipment solution for the mass production of gear injection molded parts.

These components are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this invention is that some existing devices lack an efficient ejection structure or have an unreasonable ejection component position design, resulting in concentrated force on a local area of ​​the gear during ejection, which easily leads to gear deformation and cracking. At the same time, the inefficient ejection structure also prolongs the material discharge time and cannot quickly separate the gear from the mold, affecting production efficiency. This invention, through a combination of innovative features such as uniform adsorption and picking, efficient process connection, multi-dimensional positioning, and working stability, specifically addresses the core pain points of existing devices, such as ejection deformation and cracking and low production efficiency, improving the practicality of the device and achieving high-precision molding, high-efficiency production, and high-stability operation of gear injection molded parts, providing a better equipment solution for mass production.
