[0032] The transmission mechanism 4 includes a support unit and a transmission unit;

[0033] The support unit is used to provide upward thrust to the stamping die;

[0034] The transmission unit is used to provide the mold with a thrust to move out from above the lower template 2 after the mold moves upward;

[0035] The support unit includes a support rod 401 and a first spring 402;

[0036] The support rod 401 is vertically slidably mounted on the inner wall of the lower template 2 and extends to the outside of the top end of the lower template 2. The support rod 401 is used to provide support for the mold;

[0037] The two ends of the first spring 402 are respectively clamped on the inner wall of the lower template 2 and the bottom end of the support rod 401. The first spring 402 is used to provide the support rod 401 with a thrust to move upward.

[0038] The transmission unit includes a transmission rod 403, a movable plate 404, a vertical guide groove 405, an inclined guide groove 406, a push rod 407, a positioning rod 408, and a second spring 409;

[0039] The transmission rod 403 is fixed to the outer wall of the upper template 3, and is used to give the movable plate 404 an axial movement thrust;

[0040] The movable plate 404 is axially slidably mounted on the inner wall of the workbench 1 and extends to the outside of the workbench 1. The movable plate 404 is used to synchronously drive the push rod 407 to move axially;

[0041] A vertical guide groove 405 is provided on the outer wall of the movable plate 404 , and is used to provide guidance for the vertical movement of the transmission rod 403 ;

[0042] The inclined guide groove 406 is provided on the outer wall of the movable plate 404 and is used to provide guidance for the inclined movement of the transmission rod 403;

[0043] The push rod 407 is fixed to the outer wall of the movable plate 404, and the push rod 407 is used to provide thrust for the stamped material;

[0044] The positioning rod 408 is fixed to the inner wall of the workbench 1 and penetrates into the interior of the movable plate 404. The positioning rod 408 is used to provide a guide for the axial movement of the movable plate 404.

[0045] Two ends of the second spring 409 are respectively clamped on the inner wall of the workbench 1 and the outer wall of the movable plate 404 . The second spring 409 is used to provide a restoring elastic force for the movable plate 404 after movement.

[0046] In this embodiment: when using this device, the mold to be stamped is placed on the upper surface of the lower template 2, the mold contacts the top of the support rod 401 on the upper surface of the lower template 2, and the upper template 3 is driven to dock with the lower template 2 by starting the cylinder to stamp the mold. In the process of the upper template 3 moving downward, the fixed transmission rod 403 on the outer wall of the upper template 3 will also move synchronously along the inner side of the vertical guide groove 405, and the end of the transmission rod 403 contacts the arc-shaped guide groove provided on the inner side of the vertical guide groove 405 to give the movable plate 404 a thrust away from the upper template 3, so that the movable plate 404 moves outward along the outer wall of the positioning rod 408 for a distance, and then the transmission rod 403 enters the connection between the vertical guide groove 405 and the inclined guide groove 406. At this time, the movable plate 404 will also return to its original position under the action of the second spring 409. At this time, the arc-shaped protrusion at the corner position of the vertical guide groove 405 and the inclined guide groove 406 will be located on one side of the end of the transmission rod 403. After the upper template 3 and the lower template 2 are closed and the stamping of the mold is completed, the upper template 3 moves upward under the action of the cylinder, and the mold is lifted up under the action of the first spring 402 and the support rod 401. The mold is aligned with the push rod 407, and the upper template 3 moving upward synchronously drives the transmission rod 403 to move upward. At this time, the transmission rod 403 will enter the inner side of the inclined guide groove 406 under the action of the arc-shaped protrusion inside the vertical guide groove 405, giving the movable plate 404 a thrust to approach the lower template 2. The push rod 407 contacts the outer wall of the mold and gives the mold a thrust to move the mold out from between the lower template 2 and the upper template 3 until the end of the transmission rod 403 moves to the connection between the inclined guide groove 406 and the horizontal guide groove. The movable plate 404 will be reset along the outer wall of the positioning rod 408 under the action of the second spring 409, and the transmission rod 403 will also return to its original position again. At this time, the mold will also be partially moved out from between the lower template 2 and the upper template 3, making it easier to take out the material and further improving safety.

[0047] Please refer to Figure 1-Figure 3 The end of the vertical guide groove 405 is connected to the end of the inclined guide groove 406, and the top end of the vertical guide groove 405 and the inclined guide groove 406 is provided with a horizontal guide groove connecting the end of the vertical guide groove 405 and the inclined guide groove 406. The connection between the driving end of the vertical guide groove 405 and the inclined guide groove 406 is provided with an arc guide protrusion for providing guidance for the transmission rod 403 to enter the inclined guide groove 406. The position of the push rod 407 is flush with the top of the support rod 401. The inner wall of the workbench 1 is formed with a sliding groove for axial movement of the movable plate 404. The number of support rods 401 is set to four, and multiple support rods 401 are evenly distributed on the outer wall of the lower template 2.

[0048] In this embodiment: through this structure, when the transmission rod 403 moves to the outer wall of the arc-shaped protrusion of the vertical guide groove 405, since the inner notch of the arc-shaped protrusion is facing the lower template 2 and the upper template 3, the vertical movement of the transmission rod 403 will give the inner arc-shaped protrusion of the vertical guide groove 405 a thrust, causing the movable plate 404 to move axially, so that the outer arc surface of the arc-shaped protrusion is located on one side of the end of the transmission rod 403, so that the transmission rod 403 enters the interior of the inclined guide groove 406 when it moves upward to reset.

[0049] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
