AI Technical Summary
Traditional foam shoe sole molding machines have a difficult-to-adjust mold opening and closing method, which makes it difficult to control the opening and closing force and the travel speed. This can cause the foam material to be easily torn or deformed before it is fully shaped. In addition, the lack of effective alignment guidance and slow-speed limiting mechanism results in insufficient dimensional accuracy of the molded shoe sole and mold wear, which cannot meet the needs of high-quality mass production.
It adopts a precise guiding and positioning structure, elastic buffer auxiliary components, and a linkage structure that combines magnetic locking with mechanical clamping. Combined with the hydraulic cylinder depressurization floating operation mode, it can achieve smooth and slow opening and closing of the mold and precise positioning and locking, and flexibly control the opening and closing force.
It improves the quality of shoe sole molding, reduces product damage, lowers equipment operating wear, ensures finished product dimensional accuracy and production stability, and extends the service life of molds and equipment.
