Technical Field

[0001] This utility model relates to the technical field of shoe sole injection molding machine equipment, and in particular to an automatic shoe sole clamping device for a shoe sole injection molding machine. Background Technology

[0002] In traditional shoe sole injection molding machines, mold opening and closing, and material removal are independent operations performed sequentially. This means the machine must complete one step before starting the next, leading to a prolonged overall production process. This step-by-step operation mode limits the throughput of the production line, making it difficult to improve production efficiency. The traditional step-by-step operation method also increases machine idle time, which not only reduces production efficiency but also leads to higher energy consumption. Long operating times and frequent start-ups and shutdowns increase electricity costs, negatively impacting the company's economic benefits.

[0003] Chinese patent discloses an automated production equipment for a two-color or multi-color shoe sole disc injection molding machine (publication number: CN216914623 U), which includes a turntable with multiple shoe sole molds on it. Each shoe sole mold includes a first upper mold, a second upper mold, and a lower mold. The first and second upper molds are respectively hinged to the lower mold. The first and second upper molds apply different colors to the shoe soles in the lower mold. However, the step-by-step operation mode of this automated production equipment for shoe sole disc injection molding machines limits the throughput of the production line, making it difficult to improve production efficiency. The step-by-step operation mode increases the machine's idle time, which not only reduces production efficiency but also leads to higher energy consumption. Therefore, there is a need for an automatic shoe sole clamping device for shoe sole injection molding machines. Utility Model Content

The two clamping cylinders and correspondingly arranged finished product grippers allow for the simultaneous processing of two finished shoe soles, improving production efficiency.

[0011] The advantages of this utility model are:

[0012] This application automates the injection molding, forming, and clamping processes of shoe soles, reducing manual intervention and improving production efficiency. By processing the opening / closing and scrap material removal steps in parallel, production cycle time is reduced, making the entire production process smoother and more efficient. This synchronous operation mode significantly increases the overall throughput of the production line because there is no longer a need to wait for one step to complete before proceeding to the next. In traditional step-by-step processes, equipment and human resources may be idle, waiting for the previous step to complete. Simultaneous opening / closing and scrap material removal operations can make fuller use of existing resources, reduce waste, and improve equipment utilization efficiency. Automated operation reduces the labor intensity of workers. Through precise positioning and control, the device can ensure the dimensional accuracy and consistency of shoe soles, thereby improving product quality. At the same time, automated operation reduces the impact of human factors on product quality. The scrap material removal component can collect waste generated during the production process, facilitating recycling, reducing production costs, and also benefiting environmental protection. The adjustable positioning screw design makes the device more versatile and flexible, adapting to the needs of different production lines. When it is necessary to change molds or adjust production processes, only the positioning screw needs to be adjusted for rapid switching. Attached Figure Description
