[0026] During the specific setting, one end of the bolt is inserted into the ejection hole 102, and the baffle 11 separates the bolt from the ejector rod 2. One end of the bolt is punched out by a punching device to form a hexagon socket bolt. After forming, the baffle 11 is removed and the hexagon socket bolt is ejected by the ejector rod 2. By setting the baffle 11, the strength of the bolt during the stamping process can be improved to prevent the bolt from hitting the ejector rod 2 and causing damage to the ejector rod 2.
[0027] Furthermore, two movable grooves 101 are opened on one side of the limiting groove 103, and two connecting rods 12 are fixedly connected to one side of the baffle 11. The two connecting rods 12 are respectively slidably connected in the two movable grooves 101, and one side of the two connecting rods 12 is fixedly connected to the movable plate 4, and the side of the movable plate 4 close to the push block 5 is fixedly connected to two first reinforcement plates 9, and the two first reinforcement plates 9 are respectively fixedly connected to the upper and lower surfaces of the push block 5, and the end of the push block 5 away from the movable plate 4 is fixedly connected to the connecting plate 6, and the side of the connecting plate 6 away from the push block 5 is fixedly connected to two limiting rods 7, and one side of the mold body 1 is fixedly connected to a fixed plate 8, and the two limiting rods 7 slide through the fixed plate 8, and a second reinforcement plate 10 is fixedly connected between one side of the fixed plate 8 and the mold body 1.
[0028] In the present application, the driving rod 3 is driven by the driving device, driving the connecting rod 12 and the movable plate 4 to move to the right, so that the baffle 11 and the push block 5 move to the right at the same time, the movable rod slides along the movable groove 101, the baffle 11 slides along the inner wall of the limit groove 103, and the push block 5 drives the connecting plate 6 and the limit rod 7 to move synchronously, and the limit rod 7 slides along the hole of the fixed plate 8.

In the early stage of the movement of the push block 5, the push rod 2 does not move, and the baffle 11 moves to the right. When the roller 202 contacts the inclined surface, the baffle 11 is located on the right side of the ejection hole 102. As the push block 5 continues to move, the push rod 2 moves toward the direction close to the hexagon socket bolt under the action of the inclined surface of the push block 5 until the hexagon socket bolt is ejected.

In the process of the push block 5 moving to the right, the roller 202 rolls along the side wall of the push block 5. The right end of the push block 5 is horizontal, and the left end is provided with an inclined surface. In the early stage of the movement of the push block 5, the ejector rod 2 does not move, and the baffle 11 moves to the right.
