In addition, a number of evenly distributed support rods 3 are fixed between the lower mold base 206 and the bottom plate 1; at the same time, a slide groove 4 is opened on one side of the bottom plate 1 close to the mold body 2, and the top end of the slide groove 4 is slidably connected to a waste box 5 located below the lower mold base 206; not only that, two closing rods are connected to the top of the bottom plate 1 A mounting frame 6 is symmetrical to the mold body 2, with the middle of the mounting frame 6 being empty, and the top of each mounting frame 6 is hinged with a rocker arm 7 through a rotating shaft, and the hinged position is at one end of the rocker arm 7, and the bottom end of each rocker arm 7 is installed with a knocking hammer 8 located above the lower mold base 206; in addition, a driving mechanism 9 is provided on the bottom plate 1 for driving the rotating shaft on the mounting frame 6 to rotate, so that under the action of the driving mechanism 9, the rotating shaft on the mounting frame 6 can be driven to rotate, so that the rocker arm 7 drives the knocking hammer 8 to knock the lower mold base 206, so that the waste in the lower mold base 206 and the die 205 can be knocked down and fall into the waste box 5, so that the waste in the stamping mold can be cleared to prevent the waste from affecting the subsequent processing of the workpiece.The driving mechanism 9 includes a vertical plate 901 fixed on the top of each mounting frame 6 and away from the side of the knocking hammer 8. A spring 902 is connected between each vertical plate 901 and the corresponding swing rod 7. At the same time, a protrusion 903 is installed on the top of each swing rod 7. The side of each protrusion 903 close to the vertical plate 901 is arc-shaped. In addition, a knocking mechanism 10 for repeatedly knocking the protrusion 903 is arranged on the bottom plate 1. The knocking mechanism 10 includes a rotating rod 1001 rotatably connected to each mounting frame 6 through a bearing, and a fixed rod 1002 perpendicular to it is fixed on each rotating rod 1001. A connecting frame 1003 is installed on the top of each fixed rod 1002. A roller 1004 for knocking the protrusion 903 is hinged on each connecting frame 1003 through a rotating shaft. At the same time, a rotating mechanism 11 for driving the rotating rod 1001 to rotate is arranged on the bottom plate 1. The rotating mechanism 11 includes two servo motors symmetrically installed on the bottom plate 1 Machine 1102, at the same time, the ends of the two rotating rods 1001 that are away from each other extend through and extend to the outside of the corresponding mounting frame 6, and a driven pulley 1101 located outside the corresponding mounting frame 6 is fixed on the outside thereof, and a driving pulley 1103 is fixedly sleeved on the outer peripheral side of the output shaft of each servo motor 1102, and a tensioned belt 1104 is matched and connected between each driving pulley 1103 and the corresponding driven pulley 1101. In this way, under the action of the servo motor 1102, the rotating rod 10 can be driven to rotate through the driving pulley 1103 and the driven pulley 1101, so that the roller 1004 on the rotating rod 1001 continuously knocks the protrusion 903. In this way, under the action of the spring 902, the rocker rod 7 will drive the knocking hammer 8 to continuously knock on the lower mold base 206. It is worth mentioning that because the side of the protrusion 903 close to the vertical plate 901 is arc-shaped, in order to facilitate knocking, the rotating rod 1001 rotates counterclockwise.External blocks 12 are installed on the front and rear sides of the lower die base 206, and a guide rod 13 is fixed to the top of each external block 12. Guide sleeves 14 that movably sleeve the guide rod 13 are installed on the front and rear sides of the upper die base 201. Each support rod 3 is retractable. Each support rod 3 includes a sleeve rod 301 fixed to the bottom end of the bottom plate 1. The top of each sleeve rod 301 is movably inserted with an insertion rod 302 fixed to the bottom end of the lower die base 206. The bottom plate 1 is provided with a The fixing mechanism 15 includes a driving motor 1501 symmetrically mounted on the bottom plate 1, and a screw rod 1502 located in the vertical direction is fixedly connected to the output shaft of each driving motor 1501, and a telescopic tube 1503 is threadedly sleeved on the outer peripheral side of each screw rod 1502. At the same time, a coordination block 1504 located above the corresponding telescopic tube 1503 is installed on both sides of the lower mold base 206, and a fixed screw rod 1502 is sleeved on the outer peripheral side of each telescopic tube 1503. The outer frame 1505 is fixed on the base plate 1. Moreover, when the driving motor 1501 drives the screw rod 1502 to rotate, the telescopic tube 1503 will rotate together instead of moving up and down. Therefore, a limiting mechanism 16 for limiting the rotation of the telescopic tube 1503 is also provided on the base plate 1. The limiting mechanism 16 includes a cross-shaped limiting groove 1601 respectively opened in each outer frame 1505 and distributed along its height direction. At the same time, a limiting block 1602 which is matched with the corresponding limiting groove 1601 is installed on the outer side of each telescopic tube 1503, that is, the cross groove of the outer frame 1505 is engaged and slidably connected with the cross block connected to the outer side of the telescopic tube 1503. In this way, when the screw rod 1502 rotates, the telescopic tube 1503 will not rotate, but move up and down, thereby pushing the entire mold body 2 to change its height, so that the lower mold base 206 in the mold body 2 can adjust its height to adapt to the striking position of the striking hammer 8.

[0015] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
