Description

Technical Field

[0001] This utility model relates to the field of hinge reinforcement plate processing technology, specifically a stamping die for automotive hinge reinforcement plates. Background Technology

[0002] Automotive hinge reinforcement plates are a type of reinforcing component in the vehicle body structure. They are mainly used to enhance the strength, durability, and safety of the connection between the door hinge and the vehicle body. They are usually located on the A-pillar, B-pillar, or inside the door frame and are fixed to the door hinge (such as a hinge-type hinge) by bolts or welding to form a multi-layered reinforced structure. The reinforcement plates are usually manufactured by stamping.

[0003] Chinese patent CN207386359U discloses a stamping die for an automotive hinge reinforcement plate partition. This die, through the coordinated use of a lower die, a fixed rod, an upper die, a slide rail, a support block, a baffle, a connecting plate, bolts, a connecting rod, a spring, a limiting plate, a sleeve, a positioning rod, a clamping plate, a clamping rod, and a limiting block, solves the problem of repeated alignment required by existing stamping dies during installation. This automotive hinge reinforcement plate partition stamping die offers advantages such as rapid positioning, reducing replacement time, improving user efficiency, and facilitating user operation.

[0004] While the above solutions utilize multiple structures to achieve rapid positioning during mold installation, the thinness of the reinforcing plate means that any foreign matter, whether in the upper die protrusion or the lower die cavity, can negatively impact the forming quality during stamping. Therefore, we provide a stamping die for automotive hinge reinforcing plates to address these issues. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] like Figure 1-4 As shown, this utility model provides a technical solution: a stamping die for an automotive hinge reinforcement plate, including a bracket assembly, a die assembly, a hydraulic cylinder 5, an air blowing assembly, and an air inflation assembly.

[0031] The support assembly includes a base plate 1, a column 3 and a top plate 4. The two ends of the column 3 are fixedly connected to the base plate 1 and the top plate 4, respectively. The bottom surface of the base plate 1 is fixedly connected to a support leg 8.

[0032] The base plate 1 is supported by the support legs 8, which raise the bottom of the base plate 1 to a certain height from the ground, and the base plate 1, the column 3 and the top plate 4 can form a frame structure.

[0033] The mold assembly includes a lower mold base 2 and an upper mold base 7 mounted on the base plate 1. The upper mold base 7 is located above the lower mold base 2. The lower mold base 2 is a lower mold with a forming cavity inside, and the upper mold base 7 is an upper mold with a protruding end. The stamping and forming of the reinforcing plate is completed by closing the mold base 2 and the upper mold base 7.

[0034] In this embodiment, the hydraulic cylinder 5 is installed on the top plate 4, and the extension end of the hydraulic cylinder 5 is equipped with a lifting plate 6. The upper mold base 7 is installed on the lifting plate 6. The extension end of the hydraulic cylinder 5 drives the lifting plate 6 to move up and down, and the lifting plate 6 drives the upper mold base 7 to perform mold opening and closing movements.

[0035] The base plate 1 is inlaid with two sets of guide sleeves 9. Each guide sleeve 9 is slidably connected with a guide rod 10, and the top of the guide rod 10 is fixedly connected to the lifting plate 6. When the upper mold base 7 performs the opening and closing mold movement, the upper mold base 7 will drive the guide rod 10 to move on the guide sleeve 9, thereby guiding the upper mold base 7 and avoiding misalignment between the upper mold base 7 and the lower mold base 2.

[0036] In this embodiment, the air blowing assembly is disposed on the base plate 1 and is used to clean the lower mold base 2 and the upper mold base 7 by blowing air. The air blowing assembly includes a support plate 19 fixedly connected to the base plate 1, a second air jet pipe 18 fixedly connected to the support plate 19, and a second air supply pipe 17 fixedly connected to the second air jet pipe 18.

[0037] The second jet pipe 18 has a first bend, and the first bend faces into the molding cavity of the lower mold base 2, which can blow air to clean the molding cavity of the lower mold base 2, and the blowing air also facilitates the unloading of the reinforcing plate during material unloading.

[0038] The air blowing assembly also includes a transfer component 15 fixedly connected to the lifting plate 6. The transfer component 15 is fixedly connected to a first jet pipe 16 and a first air supply pipe 14, and the first jet pipe 16 is located above the second jet pipe 18.

[0039] The first jet pipe 16 has a second bend, which faces the protruding part of the upper mold base 7. By using the first jet pipe 16 to blow air onto the protruding part of the upper mold base 7, the protruding part can be cleaned during the mold opening process of the upper mold base 7, so as to avoid residues affecting the product quality during the next stamping.

[0040] The inflation assembly is mounted on the top plate 4 and is used to supply air to the inflation assembly by moving the lifting plate 6. The inflation assembly includes two inflation pipes 11 fixedly connected to the top plate 4. A one-way valve 20 and an air supply pipe 12 are fixedly connected to each of the two inflation pipes 11. A spiral air pipe 13 is fixedly connected to each of the two air supply pipes 12. The ends of the two spiral air pipes 13 away from the air supply pipe 12 are respectively fixedly connected to the second air supply pipe 17 and the first air supply pipe 14.

[0041] The spiral air pipe 13 is spiral-shaped. When the lifting plate 6 moves up and down, the spiral air pipe 13 can be stretched to avoid the spiral air pipe 13 from obstructing the movement of the lifting plate 6. Moreover, the spiral air pipe 13 can supply air to the first air supply pipe 14 and the second air supply pipe 17.

[0042] In this embodiment, a piston plate 21 is slidably connected inside the inflation tube 11, and a piston rod 22 is fixedly connected to each of the two piston plates 21. The end of the piston rod 22 away from the piston plate 21 passes through the inflation tube 11 and is fixedly connected to the lifting plate 6.

[0043] When the lifting plate 6 moves downward, it will drive the piston plate 21 to move inside the inflation pipe 11 through the piston rod 22, and draw outside air into the inflation pipe 11 through the one-way valve 20. When the lifting plate 6 moves upward, the piston plate 21 will compress the gas in the inflation pipe 11 and deliver the gas through the spiral air pipe 13 to the first air supply pipe 14 and the second air supply pipe 17, thus completing the cleaning of the lower mold base 2 and the upper mold base 7.
