AI Technical Summary
Existing automotive oil seal skeleton stamping dies are prone to oil seal skeletons sticking to the die during demolding, resulting in low production efficiency and unstable product quality.
The design employs a synergistic approach of a limiting slider and a demolding rod. The limiting slider precisely limits the sheet metal during the stamping process, and after stamping, the spring force of the compression spring pushes the limiting slider back to its original position, thereby driving the demolding rod to automatically eject the formed part, achieving automatic demolding.
It enables automatic demolding of oil seal skeletons, reduces manual labor and operational difficulty, improves production efficiency, and ensures stamping accuracy and product quality.
