The slide plate 83 is slidably connected to the bottom end of the inner side of the processing mold 6. The inner side of the processing mold 6 is provided with a slide groove 88 corresponding to the slide plate 83. The slide plate 83 can slide in the vertical direction along the slide groove 88. The top of the slide plate 83 is fixedly connected with a plurality of ejector rods 84 that slide with the processing groove 61. One end of the movable seat 81 is provided with a driving member 85 for driving the movable seat 81 to slide horizontally. The end of the mounting groove 7 is fixedly connected with a protrusion 86. The bottom end of the slide bar 82 is provided with a top pressing member 87 that drives the slide bar 82 to slide upward by contacting with the protrusion 86.

[0025] When unloading, the movable seat 81 is driven to slide horizontally by the driving member 85, which can make the movable seat 81 slide close to the protrusion 86, and the movable seat 81 drives the processing mold 6 and the workbench 5 to slide relative to each other, so that the processing mold 6 slides outward from the workbench 5. When the movable seat 81 slides to the position of the protrusion 86, the pressing member 87 contacts the protrusion 86 and drives the slide bar 82 to slide upward, which makes the slide plate 83 drive all the push rods 84 to slide upward, and all the push rods 84 slide in cooperation with the corresponding processing grooves 61, so that the bolts processed inside the processing grooves 61 can be ejected, thereby realizing automatic unloading of the bolts.

[0028] Furthermore, the pressing member 87 includes a mounting seat 871, which is fixedly connected to the bottom of the slide bar 82, and a pressure wheel 872 is rotatably connected to the inner side of the mounting seat 871, and the bottom end of the pressure wheel 872 contacts the bottom wall of the mounting groove 7. A return spring 873 is sleeved on the slide bar 82, and the top end of the return spring 873 contacts the movable seat 81, and the bottom end of the return spring 873 contacts the mounting seat 871. When the pressure wheel 872 contacts the protrusion 86, the pressure wheel 872 moves upward under the pressure of the protrusion 86, which makes the mounting seat 871 exert an upward force on the slide bar 82 and make it slide upward, which makes the slide plate 83 drive all the push rods 84 to slide upward, and also makes all the push rods 84 slide and cooperate with the corresponding processing grooves 61, so that the bolts processed inside the processing grooves 61 can be ejected, thereby realizing the automatic unloading of the bolts.

[0029] Furthermore, the cold heading mechanism 4 includes a top seat 41, which is fixedly connected to the top of the guide rod 2, and a cylinder 44 is fixedly connected to the top of the top seat 41, and a mounting plate 42 is fixedly connected to the output end of the cylinder 44, and the four corners of the mounting plate 42 are slidably connected to the corresponding guide rod 2, and the bottom of the mounting plate 42 is fixedly connected to a bolt pressure block 43 that slides with the processing mold 6.
