The fixed rod 805, the push plate 806 and the upper end surface of the lower mold assembly 4 are flush, and the push plate 806 and the upper end surface of the lower mold assembly 4 are slidably connected. When the mounting plate 6 and the upper mold 7 are driven downward by the hydraulic rod 5, the movable frame 801, the fixed rod 805 and the push plate 806 are moved backward through the transmission action of the connecting rod 802, so that the upper mold 7 and the lower mold assembly 4 can cooperate normally for processing. When the hydraulic rod 5 drives the mounting plate 6 and the upper mold 7 to move upward, the movable frame 801, the fixed rod 805 and the push plate 806 move forward in cooperation with the transmission action of the connecting rod 802.

[0028] The lower mold assembly 4 includes a bottom plate 401, a bottom mold 402, a positioning column 403, a movable plate 404, a vertical rod 405 and a spring 406. The bottom plate 401 is fixed to the upper end surface of the operating table 1, and the bottom mold 402 is fixed on the bottom plate 401, and the positioning columns 403 are evenly fixed on the upper end surface of the bottom mold 402.

[0029] When using the hot stamping device for automotive stamping parts, Figure 1-Figure 7As shown, the heated workpiece is placed on the bottom mold 402 by the manipulator. At this time, the lower end surface of the workpiece is in contact with the fixed rod 805 and the push plate 806, and with the action of the positioning column 403, the workpiece to be processed can be limited to ensure the processing position of the workpiece. After the workpiece is placed, the hydraulic rod 5 is controlled to extend, thereby driving the mounting plate 6 and the upper mold 7 to move downward. With the transmission action of the connecting rod 802, the movable frame 801, the fixed rod 805 and the push plate 806 can be forced to move backward, and with the sliding guide action between the slide rod 803 and the vertical plate 804 , which can ensure the stability of the movement of the movable frame 801, the fixed rod 805 and the push plate 806. When the push plate 806 moves to the rear side of the bottom die 402 and is completely separated from the bottom die 402, the workpiece falls to contact with the bottom die 402, and the upper die 7 is located above the bottom die 402 and is not in contact with the bottom die 402. At this time, the hydraulic rod 5 continues to extend to drive the upper die 7 to move downward. When the upper die 7 contacts the workpiece, pressure is applied by the hydraulic rod 5, and the upper die 7 cooperates with the bottom die 402 to achieve the hot pressing plastic processing of the workpiece. In the process of plastic processing, the movable plate 404 is subjected to The vertical rod 405 and the movable plate 404 are moved downward by force, and the sliding guide effect between the vertical rod 405 and the bottom die 402 can ensure the stability of the movement of the movable plate 404. At this time, the spring 406 is forced to shrink. When the processing is completed, the hydraulic rod 5 shrinks to drive the mounting plate 6 and the upper die 7 to move upward. When the upper die 7 moves to the top of the bottom die 402, the elastic effect of the spring 406 can make the vertical rod 405 and the movable plate 404 move upward and reset, thereby driving the processed workpiece to automatically move upward and realize the automatic demoulding effect. When the mounting plate 6 moves upward, according to the above principle, the connecting rod 80 2, the movable frame 801, the fixed rod 805 and the push plate 806 can move forward. When the push plate 806 contacts the demoulding workpiece, the workpiece can be pushed forward and fall onto the conveyor belt 1003, thereby realizing the automatic unloading of the workpiece. Then, the motor 1001 drives the transmission roller 1002 to rotate, so that the conveyor belt 1003 moves, and then the workpiece transfer function can be realized, so as to facilitate subsequent processing. In addition, during the workpiece transfer process, the stopper 1004 can prevent the workpiece from sliding, thereby ensuring the stability of the workpiece transfer.

[0030] The cleaning assembly 9 includes a collection box 901, a high temperature resistant brush plate 902, a cross bar 903, a fixed frame 904, a slider 905 and a slide plate 906. The collection box 901 is arranged below the upper mold 7, and the collection box 901 is fixed with a high temperature resistant brush plate 902, and the high temperature resistant brush plate 902 is slidably connected to the upper mold 7; a cross bar 903 is fixed to the rear end face of the collection box 901, and the cross bar 903 and the fixed frame 904 are slidably connected, and the fixed frame 904 is fixed to the mounting plate 6, and the distance between the fixed frame 904 and the mounting plate 6 is greater than the width of the collection box 901; a slider 905 is also fixed to the cross bar 903, and the slider 905 and the slide plate 906 are slidably connected, and the slide plate 906 is fixed to the movable frame 801;

[0031] During the processing, Figure 1-Figure 7 As shown, when the hydraulic rod 5 extends to drive the upper mold 7 to move, so that the movable frame 801 moves backward synchronously, the slide plate 906 is forced to move backward synchronously, and drives the slider 905, the cross bar 903, the collection box 901 and the high temperature resistant brush plate 902 to move backward. The sliding guide effect between the cross bar 903 and the fixed frame 904 can ensure the stability of the movement of the collection box 901 and the high temperature resistant brush plate 902. The sliding effect between the slider 905 and the slide plate 906 can make the collection box 901 and the high temperature resistant brush plate 902 move downward synchronously with the upper mold 7 to ensure the normal operation of the device. When the push plate 806 moves to the rear side of the bottom mold 402 and is aligned with the bottom mold 402, the push plate 806 moves to the rear side of the bottom mold 402 and is aligned with the bottom mold 402. When the bottom die 402 is completely separated, the collecting box 901 and the high temperature resistant brush plate 902 are moved to the rear side of the mounting plate 6 and are completely separated from the upper die 7, ensuring the normal progress of the subsequent stamping process. According to the above principle, when the movable frame 801 moves forward, the collecting box 901 and the high temperature resistant brush plate 902 move forward synchronously, and with the sliding action between the high temperature resistant brush plate 902 and the upper die 7, the debris adhered to the upper die 7 due to the stamping process can be cleaned to ensure the cleanliness of the upper die 7, thereby ensuring the subsequent processing quality. The cleaned debris falls into the collecting box 901 and is collected for subsequent cleaning. This is the working principle of the hot stamping device for automobile stamping parts.
