AI Technical Summary
In traditional zipper dies, the hook pin causes the pull ring to swing during reset, resulting in unstable swaying of the zipper head.
Design a new type of pull head mold that allows the hook to rise first and then swing to disengage from the pull ring during reset. The stable reset of the hook is achieved through the coordinated action of a cylinder and a spring. The design includes the structure of the hook limit groove, the locking pin, and the insert pin.
This ensures that the hook does not cause the pull ring to swing when it resets, making the pull head more stable and improving the stability of the pull head when it enters the chain belt.
