Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and more specifically to a molding die for molding automotive aluminum structural parts. Background Technology

[0002] Aluminum products, made from aluminum and other alloying elements, are widely used in construction, electronics, transportation, and other fields due to their low density, high specific strength, strong corrosion resistance, and good machinability. In the automotive industry, they are often used for body structural parts, wheels, etc., to reduce weight and improve fuel economy. Automotive aluminum structural parts are mostly processed using stamping forming technology. Through the up-and-down movement of the forming die and the pressure of the stamping press, the metal material is placed in the working cavity of the die. The stamping process restricts the metal material to the contour and size requirements, thereby obtaining the required stamped parts.

[0003] The shortcomings of existing technology are that after the aluminum material is formed under pressure, the structural parts are easily stuck inside the mold, requiring operators to apply greater force or use auxiliary tools to remove them, which affects work efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a forming mold for forming automotive aluminum structural parts, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forming mold for forming automotive aluminum structural parts, comprising a stamping mechanism, and further comprising: a first pushing mechanism, a buffer mechanism, an upper mold mechanism, a lower mold mechanism, and a second pushing mechanism. The top end of the stamping mechanism is fixedly connected to the bottom end of the lower mold mechanism, the top end of the upper mold mechanism is fixedly connected to the bottom end of the stamping mechanism, the bottom end of the upper mold mechanism is movably connected, the top end of the upper mold mechanism is fixedly connected to the bottom end of the second pushing mechanism, and the bottom end of the lower mold mechanism is fixedly connected to the bottom end of the first pushing mechanism. The stamping mechanism includes a worktable, and a cantilever is fixedly connected to the top end of the worktable. A hydraulic device is fixedly connected to the bottom end of the device. The bottom end of the hydraulic device is fixedly connected to the top end of the upper mold mechanism. The bottom end of the lower mold mechanism is fixedly connected to the top end of the worktable. The structure of the first pushing mechanism is the same as that of the second pushing mechanism. The first pushing mechanism includes an installation cylinder and a high-pressure air pump. A sealing piston is movably connected to the inner side wall of the installation cylinder. A connecting rod is fixedly connected to the top end of the sealing piston. A pushing block is fixedly connected to the top end of the connecting rod. A receiving groove is opened at the top end of the lower mold mechanism corresponding to the position of the pushing block. An air guide pipe is fixedly connected to the bottom end of the installation cylinder. The bottom end of the air guide pipe is connected to the output end of the high-pressure air pump through a connecting pipe.

[0006] Furthermore, a pressure spring is fixedly connected to the inner wall of the top end of the mounting cylinder, and the bottom end of the pressure spring is fixedly connected to the top end of the sealing piston.

[0007] Furthermore, the push block has a conical structure, and the top of the push block is flush with the inner wall of the bottom end of the lower mold mechanism.

[0008] Furthermore, a limiting platform is provided on the inner side wall of the mounting cylinder, and a sealing ring is fixedly connected to the side of the sealing piston.

[0009] Furthermore, the bottom end of the upper mold mechanism is provided with a mounting hole, the buffer mechanism includes a buffer spring, the top end of the buffer spring is fixedly connected to the top end of the mounting hole, the bottom end of the buffer spring is fixedly connected with a buffer pad, the top end of the mounting hole is provided with a through hole, the top end of the buffer pad is fixedly connected with a limit post, the side of the limit post is movably connected to the side of the through hole, and the top end of the limit post is fixedly connected with a limit block.

[0011] Furthermore, the top of the positioning hole is provided with a second arc angle, and the bottom of the buffer pad is provided with a first arc angle.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model uses a second pushing mechanism to push the aluminum structural component downwards and a first pushing mechanism to push the aluminum structural component upwards, preventing the aluminum structural component from getting stuck in the mold. When the first pushing mechanism is running, a high-pressure air pump fills the mounting cylinder with gas through a connecting pipe and an air guide pipe, increasing the air pressure inside the mounting cylinder. This causes the sealing piston to push the connecting rod upwards, causing the pusher block to separate the aluminum structural component from the bottom inner wall of the lower mold mechanism. After that, the gas inside the mounting cylinder is discharged, and the pusher block is put into the receiving groove, which helps to improve work efficiency.

[0014] 2. This utility model uses a hydraulic device to push the upper mold mechanism downwards. The buffer pad first contacts the lower mold mechanism and inserts into the positioning hole, aligning the upper and lower mold mechanisms. The buffer spring contracts to buffer the mechanical energy of the upper mold mechanism, reducing the impact force of the upper mold mechanism on the lower mold mechanism. This allows the upper and lower mold mechanisms to cooperate in pressing and forming the aluminum material, which helps to avoid mold damage. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The molding die for forming automotive aluminum structural parts involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1 to 5This utility model provides a forming mold for forming automotive aluminum structural parts, including a stamping mechanism 1, and further including: a first pushing mechanism 2, a buffer mechanism 3, an upper mold mechanism 4, a lower mold mechanism 5, and a second pushing mechanism 6. The top end of the stamping mechanism 1 is fixedly connected to the bottom end of the lower mold mechanism 5, the top end of the upper mold mechanism 4 is fixedly connected to the bottom end of the stamping mechanism 1, the bottom end of the upper mold mechanism 4 is movably connected, the top end of the upper mold mechanism 4 is fixedly connected to the bottom end of the second pushing mechanism 6, and the bottom end of the lower mold mechanism 5 is fixedly connected to the bottom end of the first pushing mechanism 2. The stamping mechanism 1 includes... The system includes a worktable 101, a cantilever 102 fixedly connected to the top of the worktable 101, a hydraulic device 103 fixedly connected to the bottom of the cantilever 102, the bottom of the hydraulic device 103 fixedly connected to the top of the upper mold mechanism 4, and the bottom of the lower mold mechanism 5 fixedly connected to the top of the worktable 101. The structure of the first pushing mechanism 2 is the same as that of the second pushing mechanism 6. The first pushing mechanism 2 includes a mounting cylinder 201 and a high-pressure air pump. A sealing piston 204 is movably connected to the inner side wall of the mounting cylinder 201, and a connecting rod is fixedly connected to the top of the sealing piston 204. 203. A push block 202 is fixedly connected to the top of the connecting rod 203. A receiving groove 503 is opened at the top of the lower mold mechanism 5 corresponding to the position of the push block 202. An air guide pipe 207 is fixedly connected to the bottom of the mounting cylinder 201. The bottom of the air guide pipe 207 is connected to the output end of the high-pressure air pump through a connecting pipe. When processing aluminum structural parts, the aluminum material to be processed is placed inside the lower mold mechanism 5. The hydraulic device 103 pushes the upper mold mechanism 4 downward, so that the upper mold mechanism 4 and the lower mold mechanism 5 cooperate to pressurize and form the aluminum material. Then the hydraulic device 103 drives the upper mold mechanism 4 upward. At the same time, the second pushing mechanism 6 pushes the aluminum structural component downward, and the first pushing mechanism 2 pushes the aluminum structural component upward to prevent the aluminum structural component from getting stuck in the mold. When the first pushing mechanism 2 is running, the high-pressure air pump fills the mounting cylinder 201 with gas through the connecting pipe and the air guide pipe 207, which increases the air pressure inside the mounting cylinder 201. This causes the sealing piston 204 to push the connecting rod 203 upward, so that the push block 202 separates the aluminum structural component from the bottom inner wall of the lower mold mechanism 5. Then the gas inside the mounting cylinder 201 is discharged, and the push block 202 is put into the receiving groove 503.

[0023] Among them, a pressure spring 208 is fixedly connected to the inner wall of the top end of the mounting cylinder 201. The bottom end of the pressure spring 208 is fixedly connected to the top end of the sealing piston 204. When processing aluminum structural parts, the pressure spring 208 pushes the sealing piston 204 downward so that the push block 202 automatically enters the storage groove 503.

[0024] Among them, the push block 202 has a conical structure, and the top of the push block 202 is flush with the bottom inner wall of the lower mold mechanism 5 to avoid the storage groove 503 affecting the shape of the aluminum structural parts.

[0025] The mounting cylinder 201 has a limiting platform 206 on its inner side wall to limit the sealing piston 204 and ensure that gas can smoothly enter the bottom of the sealing piston 204. A sealing ring 205 is fixedly connected to the side of the sealing piston 204 to improve the sealing between the side of the sealing piston 204 and the inner wall of the mounting cylinder 201.

[0026] The upper mold mechanism 4 has a mounting hole 401 at its bottom end. The buffer mechanism 3 includes a buffer spring 302. The top end of the buffer spring 302 is fixedly connected to the top end of the mounting hole 401. A buffer pad 303 is fixedly connected to the bottom end of the buffer spring 302. A through hole 402 is provided at the top end of the mounting hole 401. A limit post 301 is fixedly connected to the top end of the buffer pad 303. The side of the limit post 301 is movably connected to the side of the through hole 402. A limit block 305 is fixedly connected to the top end of the limit post 301. When the upper mold mechanism 4 moves downward, the buffer pad 303 first contacts the lower mold mechanism 5. The buffer spring 302 contracts to buffer the mechanical energy of the upper mold mechanism 4, reducing the impact force of the upper mold mechanism 4 on the lower mold mechanism 5.

[0027] The lower mold mechanism 5 has a positioning hole 501 at its top. The side of the positioning hole 501 is movably connected to the side of the buffer pad 303. The buffer pad 303 is inserted into the positioning hole 501 to position the upper mold mechanism 4 and the lower mold mechanism 5, ensuring that the upper mold mechanism 4 and the lower mold mechanism 5 are aligned. At the same time, when the upper mold mechanism 4 and the lower mold mechanism 5 are in contact, the buffer spring 302 is retracted into the mounting hole 401 and the positioning hole 501, ensuring that the bottom end of the upper mold mechanism 4 is tightly attached to the top end of the lower mold mechanism 5.

[0028] The positioning hole 501 has a second arc angle 502 at its top and a first arc angle 304 at its bottom, which facilitates the insertion of the buffer pad 303 into the positioning hole 501.

[0029] The working principle of this utility model is as follows: The aluminum material to be processed is placed inside the lower mold mechanism 5. The hydraulic device 103 pushes the upper mold mechanism 4 downward. The buffer pad 303 first contacts the lower mold mechanism 5 and inserts into the positioning hole 501, aligning the upper mold mechanism 4 and the lower mold mechanism 5. The buffer spring 302 contracts to buffer the mechanical energy of the upper mold mechanism 4, reducing the impact force of the upper mold mechanism 4 on the lower mold mechanism 5. This allows the upper mold mechanism 4 and the lower mold mechanism 5 to cooperate in pressing and forming the aluminum material. Then, the hydraulic device 103 drives the upper mold mechanism 4 upward, while the second pushing mechanism 6 pushes the aluminum material structure downward, and the first pushing mechanism 2 pushes the aluminum material structure upward, avoiding... When the aluminum structural component is inserted into the mold, the first pusher mechanism 2 operates. The high-pressure air pump injects gas into the mounting cylinder 201 through the connecting pipe and the air guide pipe 207, increasing the air pressure inside the mounting cylinder 201. This causes the sealing piston 204 to push the connecting rod 203 upward, causing the pusher block 202 to separate the aluminum structural component from the bottom inner wall of the lower mold mechanism 5. After that, the gas inside the mounting cylinder 201 is discharged, and the pressure spring 208 pushes the sealing piston 204 downward, causing the pusher block 202 to automatically retract into the receiving groove 503, so that the top of the pusher block 202 is flush with the bottom inner wall of the lower mold mechanism 5, thus preventing the receiving groove 503 from affecting the shape of the aluminum structural component.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
