The punch pin fixing plate 2 is used to install and embed the punch pin 4. The upper die unloading plate 3 is movably connected to the punch pin fixing plate 2. The upper die unloading plate 3 is welded or embedded with an upper die guide column 5 on the top. The top of the upper die guide column 5 passes through the punch pin fixing plate 2 and the upper die pad 1, so it can move in its through hole. The upper die guide column 5 is used to guide the upper die pad 1 and the punch pin fixing plate 2. The bottom of the punch pin fixing plate 2 is located parallel to the upper die guide column 5 and is welded or embedded with a lower die guide column 6 on the other side. The bottom of the lower die guide column 6 passes through the upper die unloading plate 3, so it can move in its through hole. The lower die guide column 6 is used to guide and position the lower die concave template 7. There is a lower die concave template 7 just below the upper die unloading plate 3. The lower die concave template 7 is used to place the sound insulation wall panel material that needs to be punched, and cooperates with the upper die structure to complete the punching work. A plurality of concave holes 8 are provided on the top of the lower die concave template 7. The concave holes 8 are the shapes of the sound insulation wall panel materials that need to be punched. A movable hole 9 is provided on one side of the concave hole 8. The movable hole 9 is used for the lower die guide column 6 to move inside it to provide a certain activity space for the punch pin fixing plate 2 during the stamping work. The punch pin fixing plate 2 has a plurality of T-shaped mounting grooves a10 hollowed out inside. The mounting grooves a10 are used to inlay and install the T-shaped punch matching therewith. Needle 4, a through hole 11 is installed inside the upper die unloading plate 3 and the bottom end of the punching needle 4 passes through the through hole 11, and a mounting groove b12 is provided at the lower part of the through hole 11. The mounting groove b12 is arranged at the bottom of the upper die unloading plate 3, and a mounting plate 13 is movably installed in the mounting groove b12. The mounting plate 13 is used to install a reinforcing needle 14, and the reinforcing needle 14 is welded to the bottom of the mounting plate 13. The reinforcing needle 14 is made of high-strength steel. The reinforcing needle 14, the punching needle 4, the mounting groove a10, the through hole 11 and the concave hole 8 are on the same axis. When the punching needle 4 works downward, it can drive the reinforcing needle 14 to work in turn. There are two sets of detachable connection structures on the top of the mounting plate 13. The connection structure includes a connecting plate 15. The connecting plate 15 is detachably connected to the top of the mounting plate 13 and can be connected by a latch, The upper die unloading plate 3 is connected by means of screws, etc., so as to achieve the effect of replaceable mounting plate 13. A rectangular movable groove 16 is provided inside the upper die unloading plate 3 and is located on the top side of the connecting plate 15. The connecting plate 15 is an L-shaped plate structure. One end of the top of the connecting plate 15 passes through the movable groove 16 and is slidably connected to the lower die guide column 6. The connecting plate 15 is provided with a hole matching the lower die guide column 6, so it can slide on it. A spring 17 is provided directly below the connecting plate 15. The spring 17 is sleeved on the lower die guide column 6 and the upper die guide column 5 and is located below the connecting plate 15. The spring 17 has the effect of pushing the connecting plate 15 upward, thereby driving the mounting plate 13 at the bottom to be retracted upward. The two sets of connection structures are completely consistent and are arranged on both sides of the mounting plate 13 respectively.One set of connecting structure connecting plates 15 is slidably connected to the lower die guide column 6, and the other set is slidably connected to the upper die guide column 5. The connecting structure is used to install the mounting plate 13, and assists the mounting plate 13 to move and rebound in the mounting groove b12 during operation.

[0027] Furthermore, fixing structures are respectively installed at the bottom of both sides of the mounting plate 13, and screw holes a18 are provided on the bottom of both sides of the mounting plate 13. Bolts 19 are threadedly connected to the screw holes a18. Screw holes b20 are provided at the bottom of the connecting plate 15. One end of the bolt 19 away from the screw hole a18 is threadedly connected to the screw hole b20 at the bottom of the connecting plate 15 to achieve the effect of installing the mounting plate 13.

[0028] Furthermore, a plurality of fixing structures are evenly arranged at the bottom of both sides of the mounting plate 13 , thereby further improving the installation stability of the mounting plate 13 .

[0029] Furthermore, two upper die guide columns 5 and two lower die guide columns 6 are provided and are respectively arranged on both sides of the punch pin fixing plate 2 and are arranged in a rectangular shape. The two connecting plates 15 are respectively slidably connected to the upper die guide columns 5 and the lower die guide columns 6 on both sides, thereby further improving the stability of the movement of the mounting plate 13.

[0030] Furthermore, a limiting groove 21 is provided at the top of the mounting plate 13 . The limiting groove 21 is located below the punching pin 4 and is coaxial with the punching pin 4 . Meanwhile, the punching pin 4 and the limiting groove 21 match each other in size, and the limiting groove 21 is circular.

[0031] Furthermore, a plurality of threaded holes 22 are provided at the bottom of the mounting plate 13 , and threads 23 matching the threaded holes 22 are provided on the upper surface of the reinforcing pin 14 , and the reinforcing pin 14 is threadably connected to the threaded holes 22 to achieve the purpose of installing the reinforcing pin 14 .

[0032] The working principle of this embodiment is as follows: during installation, firstly, the end of the reinforcing needle 14 with the thread 23 is threadedly connected to the threaded hole 22 at the bottom of the mounting plate 13 to achieve the effect of installing the reinforcing needle 14, and finally, the reinforcing needle 14 on the mounting plate 13 is placed downward in the mounting groove b12, and then the corresponding screw hole a18 and screw hole b20 are aligned to ensure that the limit groove 21 is coaxial with the punch needle 4, and finally, it is fixed by the bolt 19 to complete the installation of the mounting plate 13. When working, first place the sound insulation wallboard material above the concave hole 8, and when the punch press drives the upper die pad 1, the punch needle fixing plate 2 and the upper die unloading plate 3 to move downward, first the upper die unloading plate 3 contacts the lower die concave template 7, and at the same time The lower die guide column 6 moves in the movable hole 9. When the upper die unloading plate 3 cannot move, the punch press is controlled to move downward 5mm for punching. At this time, the punch press pushes the upper die pad 1 and the punch needle fixing plate 2 downward, so that the upper die guide column 5 moves upward and moves 5mm in the upper die pad 1 and the punch needle fixing plate 2. At the same time, the lower die guide column 6 moves downward 5mm in the movable hole 9. When the punch needle fixing plate 2 moves downward, the punch needle 4 is driven to move out of the through hole 11. When the punch needle 4 contacts the limiting groove 21, the reinforcing needle 14 on the mounting plate 13 can be pushed downward to punch the lower die concave template 7. When the mounting plate 13 moves in the mounting groove b12, the connecting plates 15 on both sides are connected to the upper die guide column 5. The connecting plate 15 slides on the guide column 6 of the lower die to achieve the effect of assisting the movement of the mounting plate 13. When the connecting plate 15 slides, the squeezing spring 17 is pressed down. At this time, the spring 17 is moving in the force storage. When the reinforcing needle 14 extends downward into the concave hole 8, the punching work can be completed. At this time, the punch press drives the upper die pad 1 and the punch needle fixing plate 2 to move upward, thereby driving the punch needle 4 to be recovered. At this time, when the mounting plate 13 loses the limit of the punch needle 4, the spring 17 makes an elastic movement again to push the connecting plates 15 on both sides upward. At this time, the connecting plate 15 shrinks in the movable groove 16, thereby achieving the effect of shrinking the mounting plate 13, so that the mounting plate 13 and the reinforcing needle 14 move in the mounting groove b12 to complete the storage, and finally drives the upper die unloading plate 3 to separate from the lower die concave template 7. When disassembling, the bolt 19 can be removed again to replace the mounting plate 13 to achieve the effect of replacing the entire reinforcement needle 14. At the same time, when individual reinforcement needles 14 are damaged, the surface thread 23 and the threaded hole 22 can be separated by rotating the reinforcement needle 14, thereby achieving the effect of replacing individual reinforcement needles 14, greatly improving the service life of the punching needle 4, avoiding long-term friction with the material to cause damage to it, thereby requiring the cost of replacing the entire punching needle 4, and avoiding the traditional replacement of the punching needle 4. The upper mold unloading plate 3, the upper mold pad 1 and the punching needle fixing plate 2 and other upper mold structures need to be disassembled, which is very inconvenient, greatly improving the service life and ease of use of the stamping die for the production of sound insulation wall panels, thereby reducing its use cost.
