It can be understood that the above solution can be used to facilitate the loading and unloading of materials by the workers, and can also be used to position the lower die 103.

[0021] In this specific embodiment, the stamping machine body 101 is equipped with a hydraulic cylinder and a punch. The hydraulic cylinder drives the punch to descend, thereby stamping the automotive parts in the lower die 103.

[0022] The lower die 103 is slidably connected to the press body 101 and located on one side of the press body 101. The drive seat 104 is fixedly connected to the press body 101 and located on the side of the press body 101 near the lower die 103. The guide member 107 is disposed on the lower die 103. The lifting seat 106 is slidably connected to the lower die 103 through the guide member 107. The moving shaft 105 is fixedly connected to the lifting seat 106 and slidably connected to the drive seat 104, and passes through the drive seat 104. The drive seat 104 has a drive groove 120, which is connected to the moving shaft 104. Shaft 105 is fitted; two lifting seats 106 are provided, respectively located on both sides of the moving shaft 105; the guide member 107 is used to guide the movement of the lifting seats 106; the drive groove 120 has an inclined section in the middle; the press body 101 is also equipped with a drive structure, which includes a rotary motor 117, a threaded rod 118, and a threaded sleeve 119.

On 118, the rotary motor 117 drives the threaded rod 118 to rotate, which in turn drives the threaded sleeve 119 to move, thereby driving the lower die 103 to move. The drive structure is existing technology, and its working principle and structure will not be described in detail here. In use, the drive structure drives the lower die 103 to move, so that the lower die 103 moves to the punch on the press body 101. At this time, the press body 101 performs stamping processing on the workpiece. After the workpiece is stamped, the drive structure is activated to drive the lower die 103 to move, which in turn drives the workpiece to move, so that the lower die 103 carries the workpiece out from under the punch. During the movement of the lower die 103, the lower die 103 carries the workpiece out from under the punch. The guide member 107, the lifting seat 106, and the moving shaft 105 are moved, causing the moving shaft 105 to move along the drive groove 120. When the moving shaft 105 moves to the inclined section on the drive groove 120, the moving shaft 105 rises along the drive groove 120, thereby driving the lifting seat 106 to rise, causing the lifting seat 106 to push out the workpiece inside the lower die 103. At the same time, the lower die 103 is moved away from under the punch of the impact machine body, making it convenient for workers to load and unload materials, thereby achieving convenient material unloading and enabling the lower die 103 to be moved away from under the punch of the stamping machine body 101 for convenient loading and unloading.

During the stamping process, the columns 109 are retracted into the through holes to avoid affecting the stamping of the workpiece. During the unloading process, the columns 109 extend out of the through holes and push the workpiece out.

[0024] Meanwhile, the guide rod 110 is fixedly connected to the lower mold 103 and is disposed on the lower mold 103; the guide seat 111 is slidably connected to the guide rod 110 and fixedly connected to the base plate 108, and is sleeved on the guide rod 110; two guide members 107 are disposed on one of the base plates 108, and the guide rod 110 guides the lifting and lowering of the guide seat 111, thereby guiding the movement of the base plate 108, so that the base plate 108 can only move along the length direction of the guide rod 110, thereby improving the stability of the base plate 108 when it moves.

[0025] In addition, the limiting groove 112 is disposed on the side of the lower die 103 near the press body 101; the limiting protrusion 113 is disposed on the side of the press body 101 near the limiting groove 112, and the limiting protrusion 113 cooperates with the limiting groove 112; the limiting protrusion 113 guides the movement of the lower die 103, thereby improving the stability of the lower die 103 during the removal process.

[0026] Finally, the movable plate 115 is slidably connected to the press body 101 and located on one side of the press body 101; the positioning pin 116 is fixedly connected to the movable plate 115 and located on the side of the movable plate 115 near the lower die 103; two positioning components 114 are provided and located on the left and right sides of the lower die 103 respectively. The positioning component 114 also includes a cylinder, which is mounted on the frame, and the output end of the cylinder is connected to the movable plate 115. Since the lower die 103 is slidably mounted on the press body 101, in order to prevent the lower die 103 from shaking during the stamping process, the lower die 103 is provided with... The lower die 103 is provided with a positioning hole that cooperates with the positioning pin 116. When the lower die 103 moves out, the cylinder drives the moving plate 115 and the positioning pin 116 to move, so that the positioning pin 116 moves out of the positioning hole on the lower die 103, at which time the lower die 103 can move. During the stamping process, the lower die 103 is moved to below the punch, and the cylinder drives the moving plate 115 and the positioning pin 116 to move, so that the positioning pin 116 extends into the positioning hole on the lower die 103. Thus, the lower die 103 is positioned by the two positioning pins 116, so as to prevent the lower die 103 from shaking during the stamping process and affecting the stamping.

[0027] When using the mold ejection device of this utility model, when the stamping is completed and the workpiece needs to be unloaded, the drive structure on the stamping machine body 101 is activated to drive the lower mold 103 to move, so that the lower mold 103 drives the base plate 108, the column 109 and the moving shaft 105 to move. The moving shaft 105 moves along the drive groove 120. When the moving shaft 105 moves to the inclined section on the drive groove 120, the moving shaft 105 rises along the inclined section. At this time, the moving shaft 105 drives the base plate 108 and the column 109 to rise, so that the column 109 extends out from the through hole on the lower mold 103, thereby ejecting the stamped workpiece. At the same time, the lower mold 103 moves out from under the punch, which is convenient for the operator to load and unload the workpiece.
