AI Technical Summary

Technical Problem

The uneven surface of the mold causes unstable positioning during clamping, resulting in shaking during processing and requiring frequent position adjustments, which affects processing efficiency.

Method used

The device employs a spiral sliding structure with a mosquito coil ring and a bottom groove on the positioning plate, combined with motor-driven bevel gear transmission, to achieve four-way synchronous clamping and adjustment; 360° multi-angle positioning is achieved through the elastic cooperation of steel balls and fixed rings; the design of the telescopic rod and elastic rubber sheet on the surface of the positioning plate adaptively conforms to the curved surface of the mold.

Benefits of technology

This ensures the stability of mold processing, avoids shaking, improves processing accuracy and efficiency, and solves the problems of unstable mold positioning and frequent adjustments.
