[0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, certain shapes and dimensions. It is one of the two major components of forging. Through forging, defects such as as-cast porosity generated during the smelting process of metals can be eliminated, and the microstructure can be optimized.

The upper surface of the housing is fixedly connected with a die body. The inner surface of the die body is provided with a parent ejector pin. The parent ejector pin includes a primary ejector pin. A secondary ejector pin is slidably connected to the inner surface of the primary ejector pin. A child ejector pin is arranged outside the secondary ejector pin. The outer surface of the child ejector pin is slidably connected to the inner surface of the housing. A connecting rod is fixedly connected to the outer surface of the bottom end of the child ejector pin. A ejecting device is arranged at the bottom of the connecting rod. A self-cleaning device is arranged at the bottom of the ejecting device. It solves the problem that traditional equipment cannot handle the accumulated dirt inside during long-term operation, and can achieve the work of using fewer power units for multiple linkage powers. It also solves the problem that traditional equipment cannot perform secondary ejection, and the design of the hollow screw can facilitate the subsequent maintenance of the ejector pin.

[0004] When the device is in use, pressure is applied to the metal blank by forging machinery to cause plastic deformation. Then, after the product in the die holder is ejected, the processed product needs to be removed manually subsequently. However, when manually picking up the ejected product in close proximity to the forging table, if a equipment failure causes the forging machinery to descend, it may cause work injury problems.
