AI Technical Summary
Existing automotive airbag frame molding dies are difficult to process, costly, and difficult to maintain and repair. In particular, the corners and narrow spaces on the fixed mold core are difficult to process, requiring high-end equipment and complex procedures.
The forming grooves on the fixed mold core are separated into forming strips and blocks that can be processed separately, including rectangular convex rings, trapezoidal inserts and corner blocks. Some forming functions are transferred to convex blocks that can be used by ordinary processing equipment, simplifying the processing steps and reducing equipment requirements.
It reduces processing difficulty and cost, while simplifying maintenance and repair processes, enabling the airbag frame to be formed on ordinary equipment, thus improving production efficiency and reducing the difficulty of later maintenance.
