It is a key process equipment to ensure the appearance quality and structural safety of automobile bodies.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, existing anti-wrinkle forming dies for automotive stamping parts lack a structure for pre-degreasing the stamping parts, which leads to impurities affecting the fit between the die and the sheet metal. This results in insufficient local pressure, uncontrolled material flow, and wrinkles during stamping.

[0004] To address this, a wrinkle-resistant forming mold for automotive stamping parts is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-wrinkle forming mold for automotive stamping parts, which can solve the problem that existing automotive stamping parts lack a pre-degreasing structure, resulting in impurities affecting the fit between the mold and the sheet metal, thus causing insufficient local pressure, uncontrolled material flow, and wrinkles during stamping.

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A mold for forming anti-wrinkle automotive stamping parts includes a support base 1, a lower mold 2 mounted on the top of the support base 1, a drying mechanism 3 welded to the rear side of the support base 1, a pretreatment mechanism 4 welded to the rear side of the drying mechanism 3, a support beam 5 welded to the top of the support base 1, an electric hydraulic jack 6 mounted on the top of the inner side of the support beam 5, a lower pressure plate 7 welded to the telescopic end of the bottom of the electric hydraulic jack 6, and a pretreatment mechanism 4 including a water tank 41, a stirring rod 42, a servo motor 43, a mounting beam 44, an electric cylinder 45, a limit rod 46, a storage shell 47, and a PLC controller 48. The water tank 41 is welded to the rear side of the drying mechanism 3, the stirring rod 42 is rotatably connected to the bottom of the inner side of the water tank 41, and a connecting shaft is connected to the rear side of the stirring rod 42 via a flat key.

[0026] In this embodiment: a support base 1 provides a stable mounting platform for components such as the lower mold 2, drying mechanism 3, and support beam 5. The lower mold 2 cooperates with the upper mold to form the stamped part. The support beam 5 provides stable mounting support for the electric hydraulic jack. The electric hydraulic jack 6 serves as a power source, driving the lower pressure plate 7 through its telescopic end to achieve vertical pressure output. The lower pressure plate 7 transmits the power of the electric hydraulic jack 6 to the lower mold 2. The water tank 41 provides storage space for the degreasing agent. The stirring rod 42, driven by the servo motor 43, stirs the degreasing agent in the water tank 41 to ensure uniform solution concentration, avoiding incomplete cleaning due to local concentration differences, and ensuring effective removal of oil stains from the sheet surface. If the results are consistent, the servo motor 43 provides stable power to the stirring rod 42, and the mounting beam 44 provides a mounting carrier for the electric cylinder 45 and the limit rod 46. The electric cylinder 45 serves as the power source for the storage shell 47, and drives the storage shell 47 to rise and fall through the telescopic end, controlling the soaking time and depth of the board in the water tank 41. The limit rod 46 guides and limits the left side of the storage shell 47 to ensure that the storage shell 47 remains horizontal and stable during the rising and falling process. The storage shell 47 is used to place the board to be treated, so that the board can enter and exit smoothly in the degreasing agent, ensuring that all parts of the board can fully contact the degreasing agent and improve the cleaning effect. The PLC controller 48 can control the electric cylinder 45, the electric hydraulic jack 6, and the servo motor 43.

[0027] Specifically, such as Figure 2 , Figure 3 As shown, the servo motor 43 is installed on the rear side of the water storage tank 41. The output end of the servo motor 43 passes through the water storage tank 41 and is fixedly connected to the rear side of the connecting shaft. The mounting beam 44 is welded to the top of both sides of the water storage tank 41. The electric cylinder 45 is installed on the top of the inner side of the right mounting beam 44. The limit rod 46 is welded to the top of the inner side of the left mounting beam 44. The storage shell 47 is slidably connected to the inner side of the water storage tank 41. The right side of the storage shell 47 is fixedly connected to the telescopic end at the bottom of the electric cylinder 45. The left side of the storage shell 47 is slidably connected to the surface of the limit rod 46. The PLC controller 48 is installed on the left side of the water storage tank 41.

[0028] Specifically, such as Figure 4 As shown, the drying mechanism 3 includes a drying box 31, three air outlets 32, several semiconductor heating plates 33, three mounting pipes 34 and an exhaust fan 35. The drying box 31 is welded to the rear side of the support base 1.

[0029] Specifically, such as Figure 4 As shown, the air outlet 32 ​​is located at the top inside the drying chamber 31, and the semiconductor heating plate 33 is installed at the bottom inside the drying chamber 31.

[0030] In this embodiment: By setting up a drying chamber 31 to provide space for drying the board, heat loss is reduced and drying efficiency is improved. The air outlet 32 ​​blows the hot air generated by the exhaust fan 35 upwards onto the surface of the board, enhancing heat exchange efficiency, accelerating moisture evaporation, and ensuring rapid drying of the board. The semiconductor heating plate 33 provides a stable heat source, directly converting electrical energy into heat energy to heat the air inside the drying chamber 31, providing continuous heat for drying the board. The mounting pipe 34 provides a mounting and fixing structure for the exhaust fan 35, ensuring stable operation of the fan, and guiding the airflow direction so that the air energy is concentrated and blown onto the board through the air outlet 32. The exhaust fan 35 blows the heat generated by the semiconductor heating plate 33 upwards onto the surface of the board through the air outlet 32, accelerating moisture evaporation and improving drying speed and effect.

[0031] Specifically, such as Figure 4 As shown, the mounting pipe 34 is fixedly connected to the top of the inside of the drying box 31, and the exhaust fan 35 is installed at the bottom of the inside of the mounting pipe 34.

[0032] Specifically, such as Figure 5 As shown, baffles 8 are welded to both sides of the top of the drying oven 31, and the surface of the baffles 8 is coated with anti-corrosion paint.

[0033] In this embodiment: by setting baffle 8, the board to be dried can be limited, and by setting anti-corrosion coating, its durability can be enhanced and it can adapt to humid and high temperature environment.

[0034] Specifically, such as Figure 5 As shown, a filter ring 9 is movably connected to the top of the inner side of the air outlet 32, and the surface of the filter ring 9 is coated with an anti-corrosion coating.

[0035] Specifically, such as Figure 5 As shown, ventilation openings 10 are provided on both sides of the drying oven 31, and a dust filter 11 is movably connected to the inner side of the ventilation opening 10.

[0036] In this embodiment: by setting the filter ring 9, dust can be prevented from entering the inside of the mounting pipe 34. By setting the anti-corrosion coating, it can resist the erosion of water vapor and possible trace corrosive gases in the hot air environment, and enhance the durability of the filter ring 9. By setting the vent 10, air circulation inside and outside the drying chamber 31 can be realized, the air pressure inside the chamber can be balanced, and the pressure difference generated by the hot air circulation can be avoided from affecting the stability of airflow. By setting the dust filter 11, dust and debris in the external environment can be effectively blocked from entering the drying chamber 31 through the vent 10.

[0037] Working Principle: First, the operator starts the equipment and presets parameters through the PLC controller 48. The operator places the metal sheet to be stamped into the storage tank 47. After receiving the instruction, the PLC controller 48 first controls the servo motor 43 to start. The servo motor 43 drives the stirring rod 42 at the bottom of the inner side of the water tank 41 to rotate through the connecting shaft, uniformly stirring the degreasing agent in the water tank 41. At the same time, the PLC controller 48 controls the electric cylinder 45 to start. The telescopic end of the bottom of the electric cylinder 45 drives the storage tank 47 to descend smoothly until the storage tank 47 is completely immersed in the degreasing agent in the water tank 41, allowing the sheet to fully contact the degreasing agent and begin to remove surface oil and impurities. Then, when the sheet has been immersed in the degreasing agent for the preset time, the PLC controller 48 controls the telescopic end of the electric cylinder 45 to rise, causing the storage tank 47 and the sheet to detach from the degreasing agent. Subsequently, the operator removes the dried sheet from the storage tank. 47. Remove the material and place it on the top surface of the drying oven 31. At the same time, the PLC controller 48 starts the semiconductor heating plate 33 at the bottom inside the drying oven 31. The semiconductor heating plate 33 converts electrical energy into heat energy to heat the air inside the drying oven 31, providing a stable heat source for drying the material. Then, when the temperature inside the drying oven 31 rises to the preset value, the PLC controller 48 controls the exhaust fan 35 to start. The exhaust fan 35 rotates to generate airflow, guiding the hot air heated by the semiconductor heating plate 33 upward. The hot air is blown directionally onto the surface of the material through the three air vents 32 opened at the top inside the drying oven 31. After that, when the material is dried to the preset standard, the operator removes the dried material from the surface of the drying oven 31 and places it at the center of the lower mold 2. Finally, the PLC controller 48 starts the electric hydraulic jack, which drives the lower pressure plate 7 to complete the anti-wrinkle stamping operation.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
