In the middle of the bottom end of the pressing plate 8, a top film 9 is fixedly connected. Starting the hydraulic cylinder 6 can drive the pressing plate 8 and the top film 9 fixed to the pressing plate 8 to move downward.

[0034] Reference Figures 3 to 5 , A hydraulic component for forming is provided at the top of the top block 5. A groove 10 is opened at the top of the placing block 2. A square ring 11 is fixedly connected to the inner top of the groove 10. The outer part of the bottom film 3 is engaged with the inner wall of the square ring 11. Twisting blocks 12 are rotatably connected to both the left and right sides inside the groove 10. A rotating shaft 13 is fixedly connected to the bottom end of the square ring 11. The outer part of the rotating shaft 13 is rotatably connected to the inner wall of the groove 10. By rotating the twisting blocks 12, the rotating shaft 13 can be driven to rotate in the groove 10.

[0035] Cross grooves 14 are opened on the outer part of the rotating shaft 13. A sliding block 15 is slidably connected to the outer part of the rotating shaft 13. A limiting member 16 is rotatably connected to the inside of the sliding block 15. The outer part of the limiting member 16 is slidably connected to the inner wall of the cross groove 14. The limiting member 16 in the cross groove 14 of the rotating shaft 13 drives the sliding block 15 to slide on the outer part of the rotating shaft 13 when the rotating shaft 13 rotates.

[0036] Connecting rods 17 are fixedly connected to the adjacent sides of the two cross grooves 14. The outer part of the connecting rod 17 is slidably connected to the inner wall of the groove 10. A placing plate 18 is fixedly connected to the front side of the connecting rod 17. The outer part of the placing plate 18 is slidably connected to the inner wall of the groove 10. A through hole 19 is opened in the middle of the placing plate 18. Since the placing plate 18 is connected to the two sliding blocks 15 through the connecting rod 17, when the sliding blocks 15 slide, the sliding blocks 15 will synchronously drive the placing plate 18 to slide in the groove 10 through the connecting rod 17, so as to adjust the depth of the groove 10, so as to place bottom films 3 with different depths for the production of U-shaped step steel film molds with different depths.

[0037] Reference Figure 6 , A pressurizing groove 20 is opened in the middle of the bottom end of the placing block 2. An air delivery groove 21 is opened in the left inner part of the placing block 2. The air delivery groove 21 is connected to the pressurizing groove 20. An adjustable air pump 22 is fixedly connected to the left bottom end of the placing block 2. A top rod 23 is slidably connected to the inner wall of the pressurizing groove 20. Such a design is for ejecting the model.

[0038] The outside of the ejector rod 23 is slidably connected to the inner wall of the through hole 19, and the outside of the ejector rod 23 is slidably connected to the middle inner wall of the bottom film 3. The bottom end of the ejector rod 23 is fixedly connected with a limit block 24. Since the bottom film 3 has molds with different depths, the user can pre-inflate the pressurizing groove 20 through the adjustable air pump 22 to lift the top end position of the ejector rod 23 to be flush with the middle hole of the bottom film 3.

[0039] The outside of the limit block 24 is slidably connected to the inner wall of the pressurizing groove 20. A spring 25 is sleeved outside the ejector rod 23. One end of the spring 25 is fixedly connected to the top end of the inner wall of the pressurizing groove 20, and the other end of the spring 25 is fixedly connected to the top end of the limit block 24. An air valve 26 is fixedly connected to the inner bottom end of the pressurizing groove 20. By cooperating to start the air valve 26 to deflate and the elastic force of the spring 25 to drive the ejector rod 23 downward, the position where the ejector rod 23 ejects can be better adjusted.

[0040] Working principle: During use, the bottom film 3 is clamped into the groove 10 of the placing block 2, and then the corresponding top film 9 is fixed to the bottom end of the pressing plate 8 through bolts. At this time, the steel plate can be placed at the bottom end of the placing block 2. Start the hydraulic cylinder 6 to control the telescopic column 7 to expand and contract to push the pressing plate 8 and the top film 9, so that the top film 9 overlaps with the bottom film 3 to perform die pressing on the steel plate, thereby realizing the production of the U-shaped step steel mold.

[0041] When there is a production requirement for U-shaped step steel molds with different depths, the torsion block 12 can be rotated to drive the rotating shaft 13 to rotate, so that the limiting member 16 in the cross groove 14 of the rotating shaft 13 drives the slider 15 to slide outside the rotating shaft 13. At this time, because the placing plate 18 is connected to the two sliders 15 through the connecting rod 17, when the slider 15 slides, the slider 15 will synchronously drive the placing plate 18 to slide in the groove 10 through the connecting rod 17, thereby realizing the adjustment of the groove depth of the groove 10, so as to place the bottom film 3 with different depths for the production of U-shaped step steel molds with different depths.

[0042] During the die pressing process of the U-shaped step steel mold, when the pressing plate 8 drives the top film 9 to move upward, the adjustable air pump 22 fixed on the left side of the placing block 2 will be started to inflate the pressurizing groove 20 through the air delivery groove 21, so that the air cylinder pressurizes the limit block 24, so that the limit block 24 drives the ejector rod 23 to linearly move upward through the through hole 19 of the placing plate 18, and the middle hole of the bottom film 3 ejects the hydraulic mold. Since the bottom film 3 has molds with different depths, the user can pre-inflate the pressurizing groove 20 through the adjustable air pump 22 to lift the top end position of the ejector rod 23 to be flush with the middle hole of the bottom film 3, so as to realize the ejection of molds with different depths, and can cooperate to start the air valve 26 to deflate and the elastic force of the spring 25 to drive the ejector rod 23 downward, so as to better adjust the position where the ejector rod 23 ejects.
