Description

Technical Field

[0001] This utility model relates to the field of shoe sole processing equipment technology, and in particular to a fully electrically driven multifunctional shoe forming machine. Background Technology

[0002] In existing technologies, shoe outsole pressing machines generally adopt hydraulic or pneumatic drive methods. Their power source relies on the reciprocating motion of hydraulic cylinders or air cylinders, which has the following drawbacks: 1. High energy consumption and low efficiency: Hydraulic systems require independent oil pumps and pipelines, resulting in significant energy loss; pneumatic systems rely on compressed air, and air pressure fluctuations can easily lead to unstable mold closing pressure; 2. Insufficient control precision: Traditional drive methods struggle to achieve closed-loop pressure control, especially when pressing outsoles of different materials or thicknesses, easily causing product deformation or poor adhesion due to pressure deviations; 3. Poor structural stability: Existing hydraulic or pneumatic driven pressing equipment often employs a guide rod design. During mold closing, due to the excessive stroke of the guide rod, it is prone to wobbling under lateral forces, causing the upper mold assembly to shift in the mold closing position, affecting pressing accuracy. Therefore, improvements are necessary. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a fully electrically driven multifunctional shoe forming machine. By optimizing the coordinated transmission of the connecting rod layers and the rotating shaft, and combining the vertical guiding function of the guide rod, the machine significantly improves the mold closing stability and pressure control accuracy.
