AI Technical Summary
The existing molds for producing automotive skid plates suffer severe wear after stamping, requiring downtime for replacement and impacting production efficiency.
A mold structure including a platform, an upper mold assembly, and a lower mold assembly was designed. Multiple lower molds are rotated in a fixed box by a motor-driven rotating rod, enabling mold replacement without downtime. Support plates and electric cylinders are used for auxiliary support and clamping to ensure mold stability.
This enables mold replacement without downtime, improving production efficiency, reducing mold wear, and extending mold lifespan.
