The demoulding spring 8 and the ejector pin 9 are pressed into the lower mold body 401, and the workpiece contacts the clamping pin 403. At this time, the clamping pin 403 is squeezed in the lower mold body 401 to rotate, and the workpiece is bent through the clamping slot 13 provided by the clamping pin 403. After the bending is completed, the upper mold body 301 rises. At this time, the reset spring 503 drives the connecting rod 302 and the movable block 303 to reset, thereby avoiding the workpiece from being stuck by the clamping pin 403. The demoulding spring 8 pushes the ejector pin 9 through its own elastic force, so that the movable seat 402 and the workpiece rise, completing the bending and demoulding operations.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
