Abstract
The invention discloses a stamping die anti-sticking mechanism. The stamping die anti-sticking mechanism comprises a positioning sleeve, a stamping rod and a discharge device. A three-level stepped hole is formed in the positioning sleeve, a first sliding cavity, a second sliding cavity and a third sliding cavity which are sequentially communicated are formed in the three-level stepped hole, the discharge device is arranged in the third sliding cavity, a limiting plate is arranged at the tail end of the discharge device and arranged in the second sliding cavity, the stamping rod is arranged in the discharge device, the tail end of the stamping rod is arranged in the first sliding cavity through a connecting plate, an ejector pin matched with the discharge device is arranged between the connecting plate and the limiting plate, and a reset part for resetting the discharge device is arranged between the discharge device and the positioning sleeve. According to the stamping die anti-sticking mechanism, when the stamping rod finishes stamping, the ejector pin pushes the discharge device to move upwards until the stamping rod is completely sleeved with the discharge device, a workpiece probably attached to the stamping rod can be pushed down, operating safety in the stamping process is guaranteed, and the quality of products is improved.
