[0022] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not used to limit the present utility model.

[0023] Please refer to Figures 1-4 , the stamping die 1 of the present utility model includes a stamping upper die 11, a stamping lower die 12 and a first demolding component 13. The stamping upper die 11 is located directly above the stamping lower die 12. The first demolding component 13 includes a first demolding plate 131, a second demolding plate 132 and a first driving part 133. A demolding groove 111 for accommodating the first demolding plate 131 and the second demolding plate 132 is formed on the stamping upper die 11. The first driving part 133 is fixed to the top surface of the stamping upper die 11 and is inserted into the demolding groove 111 and then fixedly connected to the first demolding plate 131 to drive the first demolding plate 131 to rotate. The second demolding plate 132 is located below the first demolding plate 131 and is slidably connected to the stamping upper die 11. The top surface of the second demolding plate 132 is provided with undulating sliding tables 1321 arranged in a circumferential direction. The bottom surface of the first demolding plate 131 is provided with sliding heads 1311 that fit the sliding tables 1321. When the first driving part 133 drives the first demolding plate 131 to rotate, the sliding heads 1311 are driven to rotate and drive the second demolding plate 132 to slide relative to the stamping upper die 11 through the sliding tables 1321.

[0024] By arranging a first stripping plate 131 and a second stripping plate 132 inside the stamping upper die 11, and fixing a first driving member 133 on the stamping upper die 11 and connecting it to the first stripping plate 131, the first stripping plate 131 is driven to rotate under the drive of the first driving member 133. By arranging a sliding head 1311 on the bottom surface of the first stripping plate 131 and arranging undulating sliding platforms 1321 on the top surface of the second stripping plate 132, when the first stripping plate 131 rotates, the sliding head 1311 is driven to rotate synchronously, and the sliding head 1311 vibrates at a high frequency along the sliding platform 1321, thereby driving the second stripping plate 132 to vibrate at a high frequency relative to the stamping upper die 11. When the car door 2 gets stuck on the stamping upper die 11, the car door 2 on the stamping upper die 11 is shaken off onto the stamping lower die 12 by the second stripping plate 132 vibrating at a high frequency, and then the material taking manipulator grabs the car door 2 from the stamping lower die 12, avoiding the situation that the car door 2 gets stuck on the stamping upper die 11 and causing the material taking manipulator to be unable to perform normal material taking operations.

[0025] During stamping operations, first place the steel plate on the stamping lower die 12, control the stamping upper die 11 to descend and cover the stamping lower die 12 to stamp the steel plate into the car door 2. After stamping is completed, the stamping upper die 11 returns to its original position. When the car door 2 gets stuck on the stamping upper die 11, the first driving member 133 drives the first stripping plate to rotate, so that the first stripping plate 131 knocks on the second stripping plate 132 through the cooperation of the sliding head 1311 and the sliding platform 1321, and the second stripping plate 132 vibrates the car door 2 at a high frequency to squeeze the car door 2 out of the stamping upper die 11 and make the car door 2 fall onto the stamping lower die 12. Finally, the material taking manipulator takes out the car door 2 on the stamping lower die 12, facilitating the placement of the next steel plate on the stamping lower die 12 for stamping operations. By repeating this cycle, the automated stamping operation of the car door 2 can be achieved, avoiding the problem that the stamped car door 2 gets stuck on the stamping upper die 11.

[0026] In an embodiment of the present utility model, the first demolding assembly 13 further includes an elastic member 134. The elastic member 134 is disposed between the first demolding plate 131 and the second demolding plate 132. The elastic member 134 pulls the second demolding plate 132 to drive the sliding head 1311 to always keep in contact with the sliding table 1321. When the first driving member 133 drives the first demolding plate 131 to rotate, when the sliding head 1311 contacts the highest point of the sliding table 1321, it squeezes the second demolding plate 132 to move downward and pulls the elastic member 134 to elongate. When the sliding head 1311 contacts the lowest point of the sliding table 1321, the elastic member 134 undergoes elastic contraction, causing the second demolding plate 132 to move upward under the pulling force of the elastic member 134. As the rotation speed of the first demolding plate 131 increases, the up and down movement frequency of the second demolding plate 132 also increases, thereby forming high-frequency vibration. When the second demolding plate 132 moves downward, it exerts a squeezing action on the car door 2, and with the high-frequency vibration of the second demolding plate 132, the car door 2 stuck on the stamping upper die 11 can be squeezed out, avoiding the problem that the pick-up manipulator cannot grasp the car door 2 from the stamping lower die 12.

[0027] In an embodiment of the present utility model, slide rails are fixed on the left and right sides of the second demolding plate 132, and sliding grooves are provided at the positions of the demolding grooves 111 corresponding to the slide rails. When the second demolding plate 132 performs high-frequency vibration, the second demolding plate 132 moves up and down under the sliding cooperation of the slide rails and the sliding grooves, so as to prevent the sliding head 1311 from driving the second demolding plate 132 to rotate synchronously with the first demolding plate 131 when moving in contact with the sliding table 1321, thereby affecting the demolding effect of the second demolding plate 132 on the car door 2.

[0028] In an embodiment of the present utility model, the adjacent sliding tables 1321 are connected end to end and the connection part has a smooth transition. The end of the sliding head 1311 in contact with the sliding table 1321 is provided with a rounded corner to fit with the sliding table 1321. Thus, when the sliding head 1311 moves in contact with the sliding table 1321, the friction between the sliding head 1311 and the sliding table 1321 can be reduced, and at the same time, the movement smoothness between the sliding head 1311 and the sliding table 1321 can be improved, facilitating the rotating sliding head 1311 to squeeze the sliding table 1321 and causing the second demolding plate 132 to generate high-frequency vibration to squeeze out the car door 2 on the stamping upper die 11.

[0029] In other embodiments of the present utility model, rolling balls are provided at one end of the sliding head 1311 that fits the sliding table 1321. The rolling balls are in contact with the sliding table 1321 and are in rolling connection with the sliding table 1321. Thus, when the sliding head 1311 moves in contact with the sliding table 1321, the rolling balls are in contact with the sliding table 1321 and roll on the surface of the sliding table 1321, thereby reducing the friction between the rolling balls and the sliding table 1321 and improving the smoothness of movement between the rolling balls and the sliding table 1321. This facilitates the rotating sliding head 1311 to squeeze the sliding table 1321 through the rolling balls and cause the second demolding plate 132 to vibrate at a high frequency, so as to squeeze out the car door 2 on the stamping upper die 11.

[0030] In an embodiment of the present utility model, the stamping die 1 further includes a second demolding assembly 14. The second demolding assembly 14 includes a second driving member 141 and a third demolding plate 142. The second driving member 141 is located on one side of the stamping lower die 12 and is fixedly connected to the third demolding plate 142 to drive the third demolding plate 142 to rotate. A protruding top platform 143 is provided on one side of the third demolding plate 142. When the third demolding plate 142 rotates, it drives the top platform 143 to contact the side of the car door 2 and lift the car door 2.

[0031] By arranging the third demolding plate 142 on one side of the stamping lower die 12 and enabling the second driving member 141 to drive the third demolding plate 142 to rotate, the rotating third demolding plate 142 lifts the car door 2 on the stamping lower die 12 through the top platform 143, thus preventing the car door 2 from getting stuck on the stamping lower die 12 and causing the pick-up manipulator to be unable to remove the car door 2 on the stamping lower die 12.

[0032] In an embodiment of the present utility model, a smooth transition is adopted between the top platform 143 and the third demolding plate 142. When the second driving member 141 drives the third demolding plate 142 to rotate, first, the third demolding plate 142 fits on the car door 2, and then drives the top platform 143 to smoothly fit on the car door 2, and the car door 2 is lifted from the stamping lower die 12 under the extrusion of the top platform 143, so as to facilitate the pick-up manipulator to remove the car door 2 from the stamping lower die 12.

[0033] In an embodiment of the present utility model, the stamping die 1 further includes a frame 15 and a stamping driving member 16. The frame 15 is located above the stamping upper die 11. The stamping driving member 16 is fixed on the frame 15 and is connected to the stamping upper die 11 to drive the stamping upper die 11 to cover the stamping lower die 12.

[0034] The rack 15 provides support for the stamping upper die 11, and the stamping driving part 16 is arranged on the rack 15 so that the stamping driving part 16 drives the stamping upper die 11 to perform a stamping action. That is, the stamping driving part 16 drives the stamping upper die 11 to move towards the stamping lower die 12 and cover the stamping lower die 12, so as to stamp the steel plate placed on the stamping lower die 12 into the car door 2, thereby completing the stamping action on the steel plate.

[0035] In an embodiment of the present utility model, at least two guide rods 112 are fixed on the top surface of the stamping upper die 11. The guide rods 112 pass through the rack 15 and are slidably connected to the rack 15. When the stamping driving part 16 drives the stamping upper die 11 to move, at least two guide rods 112 provide guidance for the movement of the stamping upper die 11, so as to prevent the movement route of the stamping upper die 11 from changing and affecting the stamping quality of the car door 2.
