AI Technical Summary
When used, the stamping molds that are traditionally suitable for aluminum alloy automotive bodies are not hard and ductile, and plastic deformation and rebound problems are easily caused during the stamping process, resulting in difficulty in demolding.
A stamping mold including a base, a damper, a lower mold, a push hole, a bevel block, a cylinder and a push block are designed. The cylinder drive push block moves upward, causing the inclined block to shrink inward, thereby pushing the car body out, avoiding the difficulty of demolding caused by rebound and residual stress.
The mold pushes the car body out through the pushing block moving upwards in the pushing hole, effectively preventing the aluminum alloy plate from rebounding and residual stress, and improving the convenience of the mold.
