Description

Technical Field

[0001] This utility model relates to the field of automotive mold technology, and in particular to an automotive body panel molding mold. Background Technology

[0002] Automotive body panels are the main components of a car body. They are assembled together by welding, riveting, or bonding to form the car body shell, which not only protects the occupants and parts inside the car, but also gives the car a unique appearance.

[0003] Stamping is one of the most commonly used manufacturing processes for automotive body panels. By using a stamping die, pressure is applied to the metal sheet on a stamping press to cause it to undergo plastic deformation, thereby obtaining the required shape and size. Stamping has the advantages of high production efficiency, low cost, and high dimensional accuracy.

[0004] Currently, in commonly used automotive body panel forming dies, the workpiece is prone to movement during the stamping process, resulting in low forming accuracy and a low product qualification rate. To address this issue, an automotive body panel forming die is proposed to solve the aforementioned problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problem of workpiece movement during the stamping process, this utility model provides an automotive body panel forming mold.

[0006] This utility model is achieved using the following technical solution:

[0007] An automotive body panel molding die includes a base, support columns, a top support plate, and an electric hydraulic cylinder. Four support columns are fixed around the upper surface of the base. The top support plate is fixed to the top of the support columns. The electric hydraulic cylinder is fixed to the center of the top of the top support plate. The base also has a lower mold with a mold cavity inside and a mold base inside the mold cavity.

[0008] The output end of the electric hydraulic cylinder is provided with a telescopic rod. There are two telescopic rods arranged symmetrically. The telescopic rods pass through the top support plate. The end of the telescopic rod is provided with a mounting plate. The lower end of the mounting plate is provided with an upper mold. The two sides of the upper mold are symmetrically provided with clamping devices. The clamping devices are used to clamp the workpiece during stamping.

[0009] The clamping device includes a guide rod, a limiting block at the end of the guide rod, a clamping spring sleeved on the guide rod, a pressure plate at the end of the spring, the upper surface of the pressure plate being fixedly connected to the clamping spring, and the guide rod passing through the pressure plate.

[0010] The upper surfaces on both sides of the lower mold are provided with guide holes, which are adapted to guide rods.

[0011] The upper surface of the pressure plate is provided with a strong magnet, which is adhered to the upper surface of the pressure plate.

[0012] The lower surface of the pressure plate is provided with a rubber pad, which is adhered to the pressure plate.

[0013] The upper mold is fixedly connected to the mounting plate by bolts, and the mold base is engaged in the mold cavity.

[0014] The present invention has the following advantages over the prior art:

[0015] 1. By setting up a clamping device, the workpiece can be pressed tightly onto the lower die during the stamping process, effectively preventing the workpiece from moving, greatly improving the forming accuracy of automotive body panels, and ensuring product quality.

[0016] 2. Enhanced clamping effect: The strong magnets and rubber pads on the pressure plate further enhance the clamping effect of the clamping device. The strong magnets provide additional attraction force, and the rubber pads provide cushioning and increase friction, ensuring that the workpiece remains stable during the stamping process.

[0017] 3. The upper mold is fixedly connected to the mounting plate by bolts, and the mold base is engaged in the mold cavity. This installation method makes it easier and faster to replace the upper mold and the mold base, reduces production costs and production cycle, and improves production efficiency.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figures 1 to 4 As shown, an automotive body panel molding die includes a base 4, support columns 3, a top support plate 2, and an electric hydraulic cylinder 1. Four support columns 3 are fixed around the upper surface of the base 4, providing stable support for the entire die. The top support plate 2 is fixed to the top of the support columns 3, forming a stable frame structure. The electric hydraulic cylinder 1 is fixed to the center of the top support plate 2, serving as the power source for die stamping. A lower die 5 is also provided on the base 4, with a mold cavity 51 inside. A die base 52 is provided inside the mold cavity 51. The die base 52 is used to form specific shapes of automotive body panels and can be replaced according to different body panel shapes. It is engaged within the mold cavity 51, facilitating installation and disassembly.

[0026] The output end of the electric hydraulic cylinder 1 is provided with a telescopic rod 11. There are two telescopic rods 11 arranged symmetrically. The telescopic rod 11 passes through the top support plate 2. The end of the telescopic rod 11 is provided with a mounting plate 6. The lower end of the mounting plate 6 is provided with an upper mold 62. The two sides of the upper mold 62 are symmetrically provided with clamping devices. The clamping devices are used to clamp the workpiece during stamping.

[0027] The clamping device includes a guide rod 7, and a limiting block 71 is provided at the end of the guide rod 7. The limiting block 71 prevents the clamping spring 8 and the pressure plate 9 from dislodging from the guide rod 7. The clamping spring 8 is sleeved on the guide rod 7, and the pressure plate 9 is provided at the end of the spring. The upper surface of the pressure plate 9 is fixedly connected to the clamping spring 8, and the guide rod 7 passes through the pressure plate 9. When the lower mold 5 and the upper mold 62 are closed, the pressure plate 9 first contacts the workpiece. As the upper mold 62 continues to press down, the clamping spring 8 is compressed, generating elastic force to press the workpiece tightly onto the lower mold 5, preventing the workpiece from moving during the stamping process.

[0028] The upper surfaces on both sides of the lower mold 5 are provided with guide holes 53. The guide holes 53 are adapted to the guide rod 7. The guide rod 7 can slide up and down in the guide holes 53 to ensure the movement accuracy of the pressing device.

[0029] The upper surface of the pressure plate 9 is provided with a strong magnet 91. The strong magnet 91 is bonded to the upper surface of the pressure plate 9. The strong magnet 91 can further enhance the adsorption force of the pressure plate 9 on the workpiece and improve the pressing effect. Especially in some cases where the positioning accuracy of the workpiece is required to be high, the strong magnet 91 can effectively prevent the workpiece from undergoing slight displacement.

[0030] The lower surface of the pressure plate 9 is provided with a rubber pad 92, which is adhered to the pressure plate 9. The rubber pad 92 can play a buffering role, avoid direct rigid contact between the pressure plate 9 and the workpiece, prevent damage to the surface of the workpiece, and increase the friction between the pressure plate 9 and the workpiece, thereby further improving the stability of the pressing.

[0031] The upper mold 62 is fixedly connected to the mounting plate 6 by bolts 61. This connection method facilitates the installation and disassembly of the upper mold 62. When it is necessary to replace the upper mold 62 with a different shape, the replacement can be completed by simply unscrewing the bolts 61. The mold base 52 is engaged in the mold cavity 51.

[0032] The working principle of this utility model is as follows: When in use, the workpiece to be stamped is placed on the mold base 52 of the lower mold 5, and the electric hydraulic cylinder 1 is started. The output end of the electric hydraulic cylinder 1 drives the telescopic rod 11 to move downward. The telescopic rod 11 drives the mounting plate 6 and the upper mold 62 to move downward. During the downward movement of the upper mold 62, the pressure plate 9 of the pressing device first contacts the workpiece. As the upper mold 62 continues to press down, the pressing spring 8 is compressed, generating elastic force to press the workpiece tightly on the lower mold 5. At the same time, the strong magnet 91 attracts the workpiece, further enhancing the pressing effect.

[0033] The upper mold 62 continues to press down, closing with the lower mold 5 to stamp and form the workpiece;

[0034] After stamping is completed, the output end of the electric hydraulic cylinder 1 drives the telescopic rod 11 to move upward. The telescopic rod 11 drives the mounting plate 6 and the upper mold 62 to move upward. The clamping spring 8 of the clamping device returns to its original state, the pressure plate 9 separates from the workpiece, and the formed automotive body panel is taken out.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
