[0014] (III) Beneficial Effects
[0015] This utility model provides a cold forming punching die for a suitcase storage box, which has the following advantages:
[0016] 1. The cold forming die for the luggage storage box, through the setting of the buffer component, when punching, the upper die shell drives the moving rod to move. The moving rod moves outside the guide rod. When the moving rod moves, it squeezes the buffer spring. The buffer spring absorbs the impact force generated, thereby reducing mechanical vibration and noise, and protecting the rigid structure of the die and equipment from damage caused by instantaneous high load.
[0017] 2. This luggage storage box cold forming punching die, through the setting of the ejection component, after the die punching process is completed, the ejection hydraulic rod is activated, the ejection hydraulic rod drives the ejection plate to move, and the sliding rod guides the ejection plate to ensure that the ejection plate always maintains a vertical movement trajectory and avoids deflection. As the ejection plate rises, its working surface contacts the formed part, and the punched workpiece is smoothly ejected from the lower die cavity with constant pressure. The entire ejection process runs stably and the force is uniform, which not only ensures the complete demolding of the workpiece, but also avoids workpiece deformation or die damage caused by uneven force.

Two sets of ejector components 2 are fixedly connected inside the lower die shell 1. The ejector components 2 allow the processed die to be removed from the device. A base plate 3 is connected to the bottom surface of the lower die shell 1, and two sets of buffer components 4 are fixedly connected to the top surface of the base plate 3. The buffer components 4 reduce the impact force from the device. Each set of ejector components 2 includes two sets of ejector hydraulic rods 2 fixedly connected inside the lower die shell 1. 01. The top surfaces of the two sets of ejector hydraulic rods 201 are fixedly connected to ejector plates 202, and the bottom surfaces of the two sets of ejector plates 202 are fixedly connected to two sets of sliding rods 203; the two sets of buffer components 4 each include a positioning plate 401 fixedly connected to the top surface of the base plate 3, the top surfaces of the two sets of positioning plates 401 are fixedly connected to two sets of sleeves 402, the inside of the four sets of sleeves 402 is fixedly connected to guide rods 403, the outside of the four sets of guide rods 403 is sleeved with buffer springs 404, and one end of the four sets of buffer springs 404 is fixedly connected to a moving rod 405;
[0025] Four sets of fixing blocks 5 are fixedly connected to the top surface of the base plate 3. Each of the four sets of fixing blocks 5 has a connecting block 6 at one end. The fixing blocks 5 are used to position the device.
[0026] The top surface of the four sets of connecting blocks 6 is fixedly connected to the top plate 7, and the bottom surface of the top plate 7 is fixedly connected to the upper mold shell 8. The top plate 7 is designed to drive the upper mold shell 8 to move.
[0027] The lower mold shell 1 has two sets of grooves inside, and the two sets of ejector hydraulic rods 201 are all set inside the grooves. The grooves serve to store the ejector hydraulic rods 201.
[0028] The bottom surface of the lower mold shell 1 is provided with a positioning block 9. The interior of the positioning block 9 is provided with several sets of connecting grooves. The positioning block 9 serves to connect with the connecting pipe 10.
[0029] Several sets of connecting pipes 10 are fixedly connected to the bottom surface of the upper mold shell 8, and several sets of connecting ports 11 are opened on the top surface of the top plate 7. The connection ports 11 are used to install the device.

[0031] In this invention, the working steps of the device are as follows:
[0032] First step: During punching, the upper mold shell 8 drives the moving rod 405 to move. The moving rod 405 moves outside the guide rod 403. When the moving rod 405 moves, it squeezes the buffer spring 404. The buffer spring 404 absorbs the impact force generated, thereby reducing mechanical vibration and noise, and protecting the rigid structure of the mold and equipment from damage caused by instantaneous high load.
[0033] The second step: After the die punching process is completed, the ejector hydraulic rod 201 is activated. The ejector hydraulic rod 201 drives the ejector plate 202 to move. The sliding rod 203 guides the ejector plate 202 to ensure that the ejector plate 202 always maintains a vertical movement trajectory and avoids deflection. As the ejector plate 202 rises, its working surface contacts the molded part and pushes the punched workpiece out of the lower die cavity smoothly with constant pressure. The entire ejection process is stable and the force is uniform, which not only ensures the complete demolding of the workpiece, but also avoids workpiece deformation or die damage caused by uneven force.
