[0004] However, the mold disclosed in the above patent still has certain shortcomings in actual application. When the material strip is stamped to form the clutch adjustment plate, it will cause some metal wire or granular waste residue. Although the mold disclosed in the above patent can clean up the excess waste, it is not convenient to clean up the metal wire or granular waste residue. As a result, the waste residue remains in the mold, which can easily cause product damage. Utility Model Content
[0005] The purpose of this utility model is to provide a spring steel clutch adjusting plate forming mold to solve the problem mentioned in the background art that the existing molds are not convenient for cleaning metal wire or granular waste, resulting in waste residue in the mold and easy damage to the product.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a spring steel clutch adjusting plate forming mold, comprising an upper mold base and a lower mold base disposed at the bottom of the upper mold base, an upper cover plate installed in the recessed cavity of the top wall of the upper mold base, an upper pad plate connected to the bottom of the upper cover plate, an upper clamping plate connected to the bottom of the upper pad plate, a middle plate connected to the bottom of the upper clamping plate, a stripper plate connected to the bottom of the middle plate, an upper punch installed in the recessed cavity of the bottom wall of the middle plate, a lower pad plate connected to the top wall of the lower mold base, a concave template connected to the top wall of the lower pad plate, the concave template being located directly below the stripper plate, and an in-mold blowing mechanism provided inside the stripper plate.
[0007] Preferably, the in-mold blowing mechanism includes a blowing box embedded in the stripper plate template, and the blowing box has a first cavity and a second cavity inside the box.
[0008] Preferably, a guide rod and a reciprocating screw are provided on one side of the first cavity. The two ends of the guide rod are fixed to the two side walls of the first cavity, and the two ends of the reciprocating screw are rotatably connected to the two side walls of the first cavity via bearings. A moving block is screwed onto the surface of the reciprocating screw, and the other end of the moving block is slidably connected to the surface of the guide rod.
[0009] Preferably, a motor is installed in the cavity of the second cavity, the output end of the motor is connected to one end of the reciprocating lead screw, and a rack is fixedly connected to the top side wall of the moving block.
[0010] Preferably, the bottom wall of the air blowing box has multiple rectangular through holes that communicate with the first cavity. A vertical plate is fixedly installed on the bottom wall of the first cavity. A rotating rod is installed through the plate of the vertical plate via a bearing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention features a stripper plate with an in-mold air blowing mechanism. After the strip material is placed between the stripper plate and the concave mold plate, and the upper punch forms a spring steel clutch adjusting plate, any remaining metal wire or granular waste falls into the concave mold plate. Upon mold opening, a motor drives a reciprocating screw to rotate. Under the guidance of a guide rod, a moving block moves back and forth along the surface of the reciprocating screw, causing a rack to move as well. The rack meshes with a gear, causing the gear to rotate, which in turn rotates a rotating rod. The back-and-forth movement of the moving block causes the gear to rotate the rotating rod within a fan-shaped range. A compressed air source connected to the air pipe supplies compressed air to the air jet box inside the air blowing box. The compressed air is ejected from the air jet box and blown towards the bottom concave mold plate through a rectangular through-hole. The back-and-forth air jetting from the air jet box effectively blows away any remaining waste on the concave mold plate, preventing damage to the product caused by waste residue remaining in the mold.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution: a spring steel clutch adjustment plate forming mold, including an upper mold base 1 and a lower mold base 10 disposed at the bottom of the upper mold base 1, an upper cover plate 2 installed in the top wall cavity of the upper mold base 1, an upper pad plate 3 connected to the bottom of the upper cover plate 2, an upper clamping plate 4 connected to the bottom of the upper pad plate 3, a middle plate 5 connected to the bottom of the upper clamping plate 4, a stripper plate 7 connected to the bottom of the middle plate 5, an upper punch 6 installed in the bottom wall cavity of the middle plate 5, a lower pad plate 9 connected to the top wall of the lower mold base 10, a concave template 8 connected to the top wall of the lower pad plate 9, the concave template 8 being located directly below the stripper plate 7, and an in-mold blowing mechanism disposed inside the stripper plate 7.
[0021] The in-mold blowing mechanism includes an air-blowing box 11 embedded in the stripper plate 7 template. A first cavity 13 and a second cavity 14 are formed inside the air-blowing box 11. A guide rod 16 and a reciprocating screw 17 are arranged in the left cavity of the first cavity 13. The front and rear ends of the guide rod 16 are respectively welded to the front and rear side walls of the first cavity 13. The front and rear ends of the reciprocating screw 17 are rotatably connected to the front and rear side walls of the first cavity 13 via bearings. A moving block 18 is screwed onto the surface of the reciprocating screw 17. The other end of the moving block 18 is slidably connected to the surface of the guide rod 16. A motor 15 is installed in the cavity of the second cavity 14. The output end of the motor 15 is connected to the front end of the reciprocating screw 17 via a coupling. A rack 19 is welded to the top right side wall of the moving block 18. Multiple rectangular through holes 21 connected to the first cavity 13 are opened on the bottom wall of the air blowing box 11. A vertical plate 20 is welded to the bottom wall of the first cavity 13. A rotating rod 22 is installed on the plate of the vertical plate 20 through a bearing. A gear 24 that meshes with the rack 19 is welded to the left end of the rotating rod 22. The right end of the rotating rod 22 is installed in the cavity wall of the first cavity 13 through a bearing. An air box 23 is welded to the surface of the rotating rod 22. An air pipe 12 connected to the air box 23 is installed in the mold of the air blowing box 11.
[0022] By setting a stripper plate 7 and an in-mold blowing mechanism within it, after the strip material is placed between the stripper plate 7 and the concave mold plate 8 and stamped into a spring steel clutch adjusting plate by the upper punch 6, the remaining metal wire-like or granular waste falls into the concave mold plate 8. After mold opening, the starting motor 15 drives the reciprocating screw 17 to rotate. Under the action of the guide rod 16, the moving block 18 moves back and forth along the surface of the reciprocating screw 17. During this movement, it drives the rack 19 to move together. Since the rack 19 meshes with the gear 24, the gear... The rotation of wheel 24 drives the rotation of gear 24, which in turn drives the rotating rod 22 to rotate. Due to the back-and-forth movement of moving block 18, gear 24 drives rotating rod 22 to rotate back and forth within a fan-shaped range. As compressed air source is connected to the outside of air pipe 12, compressed air is supplied to the air jet box 23 in air blowing box 11. The compressed air is ejected through air jet box 23 and blown towards the bottom concave template 8 through rectangular through hole 21. As air jet box 23 swings back and forth to blow air, residual waste on concave template 8 can be blown away to achieve cleaning, thereby preventing waste residue from remaining in the mold and causing product damage.
