Description

Technical Field

[0001] This utility model relates to the field of aluminum part processing mold technology, specifically a forming mold for processing aluminum parts for automobiles. Background Technology

[0002] Automotive parts are all components that make up a car and serve its functions. With the rise of new energy vehicles, the production volume of aluminum casings for new energy vehicle batteries is also increasing. The aluminum casings for new energy vehicle batteries are generally processed using stamping dies. However, if the aluminum material undergoes a large-scale deformation in one go during stamping, it can lead to localized stress concentration, causing cracks or wrinkles. Staged forming breaks down the total deformation into multiple small steps, applying only limited strain each time, allowing the material to gradually adapt to the deformation. For example, first forming a rough arc contour, and then gradually tightening it to the target shape, can avoid material tearing caused by excessive stretching in a single step. Therefore, in the stamping process of aluminum casings for new energy vehicle batteries, a staged forming process that gradually reduces the size from a large stamped shape to the final dimension is generally adopted.

[0003] However, in the existing technology, due to the use of staged molding operations, each molding process requires placing the product from the previous molding into the workstation of the next process. Traditional automotive aluminum parts processing molds generally do not have automatic material transfer functions, so manual material transfer operations are required, which not only increases the workload but also reduces processing efficiency and is not conducive to practical applications.

[0004] Therefore, those skilled in the art provide a forming mold for processing aluminum parts for automotive components to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a forming mold for processing aluminum parts for automotive components. This solves the problem mentioned in the background art, where traditional forming molds for processing aluminum parts for automotive components generally do not have automatic material transfer functions, thus requiring manual and continuous material transfer operations, which not only increases the workload but also reduces processing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a forming mold for processing aluminum automotive parts, comprising a base plate, a lower mold mounted on the top of the base plate, forming grooves evenly spaced inside the lower mold, springs fixedly mounted on the bottom of the inner wall of each forming groove, a top plate slidably connected inside each forming groove, the bottom of each top plate fixedly connected to the top of the springs, a continuous material transfer assembly provided on the outer side of the top of the lower mold, and a stamping forming assembly provided on the top of the base plate above the lower mold.

[0007] The above technical solution involves installing a spring-loaded ejector plate inside the lower mold, which ejects the finished product to the top of the lower mold. Simultaneously, a continuous material transfer assembly automatically transfers the finished product to the next workstation, eliminating the need for manual material transfer. This not only reduces labor but also improves processing efficiency, making it beneficial for practical applications.

[0008] Preferably, the continuous material transfer assembly includes a first fixed plate, a second fixed plate, a U-shaped plate, a first hydraulic cylinder, a second hydraulic cylinder, a horizontal plate, and a clamping block. The first fixed plate and the second fixed plate are respectively installed at both ends of the top of the base plate and located on both sides of the lower mold. The U-shaped plate is slidably connected between the first fixed plate and the second fixed plate. The first hydraulic cylinder is fixedly connected to the side of the first fixed plate away from the lower mold, and the piston rods of the first hydraulic cylinders are all fixedly connected to the U-shaped plate. The second hydraulic cylinders are installed on both sides of the U-shaped plate and located between the first fixed plate and the second fixed plate. The horizontal plate is fixedly connected between the piston rods of the corresponding two second hydraulic cylinders. The clamping block is installed on the side of the two horizontal plates that are close to each other.

[0009] Through the above technical solution, the operation of the second hydraulic cylinder can drive the horizontal plate to move, thereby driving the clamping block to move. The clamping block can clamp the processed aluminum parts, which facilitates the operation of the first hydraulic cylinder to drive the aluminum parts to move, thereby achieving the purpose of material transfer.

[0010] Preferably, the stamping forming assembly includes an L-shaped plate, a third hydraulic cylinder, a connecting plate, and an upper die. The L-shaped plate is fixedly installed on the top of the base plate and on one side of the lower die. Two third hydraulic cylinders are installed on the top of the L-shaped plate, and the piston rods of the third hydraulic cylinders extend to the bottom of the L-shaped plate. The connecting plate is fixedly connected between the piston rods of the two third hydraulic cylinders. The upper die is equidistantly installed at the bottom of the connecting plate and its position corresponds to the forming groove.

[0011] Through the above technical solution, the operation of the third hydraulic cylinder drives the connecting plate to move up and down. The up and down movement of the connecting plate can drive the upper mold to move up and down, thereby utilizing the cooperation between the upper mold and the forming groove to perform forming processing operations on aluminum parts.

[0012] Preferably, the second fixing plate is configured as a U-shaped structure with an opening at the top.

[0013] The above technical solution allows the aluminum parts to be easily cut from the position of the second fixing plate after processing.

[0014] Preferably, the forming groove, the upper mold, and the clamping block are all configured to decrease in size from left to right.

[0015] The above technical solution facilitates the adaptation to the staged forming process of aluminum parts.

[0016] Preferably, the first hydraulic cylinder, the second hydraulic cylinder, and the third hydraulic cylinder are all electrically connected to an external PLC controller.

[0017] The above technical solution allows for the programming and control of the entire equipment using an external PLC controller.

[0018] This utility model provides a forming mold for processing aluminum parts for automotive components, which has the following beneficial effects: This automotive aluminum parts forming mold, by setting a spring inside the lower mold in conjunction with an ejector plate, can eject the product after each forming process to the top of the lower mold. At the same time, with the continuous material transfer component, it can continuously and automatically transfer the formed products to the next work station, thus eliminating the need for manual material transfer operations. This not only reduces the amount of labor but also improves processing efficiency, which is beneficial for practical applications. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Reference Figures 1-4This utility model provides a forming mold for processing aluminum parts for automotive components, including a base plate 1, which can stably place the entire equipment. A lower mold 2 is installed on the top of the base plate 1. The lower mold 2 has forming grooves 3 evenly spaced inside, which facilitate the forming of aluminum parts. Springs 4 are fixedly installed on the bottom of the inner wall of each forming groove 3. A top plate 5 is slidably connected inside each forming groove 3. The bottom of the top plate 5 is fixedly connected to the top of the springs 4. Using the action of the springs 4, the top plate 5 can move downward and compress the springs 4 during the forming process, thereby realizing the forming operation. After the forming operation is completed, the spring force of the springs 4 causes the top plate 5 to return upward and lift the processed aluminum part, moving it to the top of the lower mold 2 for subsequent processing operations.

[0023] In one aspect of this embodiment, a continuous material transfer assembly is provided on the outer side of the top of the lower mold 2. The continuous material transfer assembly includes a first fixed plate 6, a second fixed plate 7 with a U-shaped structure and an open top (the U-shaped structure and open top of the second fixed plate 7 allows the finished aluminum part to be easily unloaded from the position of the second fixed plate 7), a U-shaped plate 8, a first hydraulic cylinder 9, a second hydraulic cylinder 10, a horizontal plate 11, and a clamping block 12. The first fixed plate 6 and the second fixed plate 7 are respectively installed at both ends of the top of the base plate 1 and are located on both sides of the lower mold 2. The U-shaped plate 8 is slidably connected between the first fixed plate 6 and the second fixed plate 7. The first hydraulic cylinder 9 is fixedly connected to the side of the first fixed plate 6 away from the lower mold 2. The piston rod of the first hydraulic cylinder 9 is fixedly connected to the U-shaped plate 8. By operating the first hydraulic cylinder 9, the U-shaped plate 8 can be driven to move laterally between the first fixed plate 6 and the second fixed plate 7. The second hydraulic cylinder 10 is installed on both sides of the U-shaped plate 8 and located between the first fixed plate 6 and the second fixed plate 7. The horizontal plate 11 is fixedly connected between the piston rods of the corresponding two second hydraulic cylinders 10. The clamping block 12 is installed on the side of the two horizontal plates 11 that are close to each other. By working with the second hydraulic cylinder 10, the horizontal plate 11 can be moved, which in turn can move the clamping block 12. The clamping block 12 can clamp the processed aluminum parts, which facilitates the operation of the first hydraulic cylinder 9 to move the aluminum parts and achieve the purpose of material transfer.

[0024] In one aspect of this embodiment, a stamping forming assembly is disposed on the top of the base plate 1 and above the lower mold 2. The stamping forming assembly includes an L-shaped plate 13, a third hydraulic cylinder 14, a connecting plate 15, and an upper mold 16. The L-shaped plate 13 is fixedly installed on the top of the base plate 1 and on one side of the lower mold 2. Two third hydraulic cylinders 14 are mounted on the top of the L-shaped plate 13, and the piston rods of the third hydraulic cylinders 14 extend to the bottom of the L-shaped plate 13. The connecting plate 15 is fixedly connected between the piston rods of the two third hydraulic cylinders 14. The operation of the third hydraulic cylinders 14 drives the connecting plate 15 to move up and down. The upper mold 16 is equidistantly installed at the bottom of the connecting plate 15 and its position corresponds to the forming groove 3. The up and down movement of the connecting plate 15 drives the upper mold 16 to move up and down, thereby enabling the forming operation of the aluminum part by utilizing the cooperation between the upper mold 16 and the forming groove 3. The forming groove 3, the upper mold 16, and the clamping block 12 are all configured to decrease in size from left to right, which is convenient for adapting to the staged forming process of the aluminum part.

[0025] In one aspect of this embodiment, the first hydraulic cylinder 9, the second hydraulic cylinder 10, and the third hydraulic cylinder 14 are all electrically connected to an external PLC controller, which enables the overall equipment to be programmed and controlled.

[0026] Working principle: First, place the equipment stably and power it on. At the same time, connect the first hydraulic cylinder 9, the second hydraulic cylinder 10 and the third hydraulic cylinder 14 to the external PLC controller. The external PLC controller can be used to program and control the entire equipment. In use, the aluminum part to be processed is placed above the leftmost forming groove 3. Then, the third hydraulic cylinder 14 is controlled to work, driving the connecting plate 15 to move downward, thereby driving the upper mold 16 to move downward. When the upper mold 16 moves into the forming groove 3, the aluminum part is formed and pushed the top plate 5 to move downward, while squeezing the spring 4, thus realizing the forming operation. After the forming operation is completed, the upper mold 16 moves upward to return to its original position. Through the elastic force of the spring 4, the top plate 5 returns to its original position and lifts the processed aluminum part, moving it to the top of the lower mold 2, thus facilitating subsequent processing operations. Then, by controlling the second hydraulic cylinder 10 to work, the horizontal plate 11 is moved, which in turn moves the clamping block 12. The clamping block 12 can clamp the processed aluminum part. At the same time, in conjunction with the work of the first hydraulic cylinder 9, the U-shaped plate 8 moves laterally between the first fixed plate 6 and the second fixed plate 7, thereby moving the processed aluminum part to the position of the next forming groove 3, thus achieving the purpose of material transfer. There is no need for manual material transfer operation, which not only reduces the amount of labor, but also improves the processing efficiency, which is beneficial to practical applications. Then, the above processing operations are repeated to continuously shape the aluminum parts in sequence, thereby gradually meeting the aluminum shell standards required for new energy vehicles. After the final processing step, the workpiece can be unloaded through the position of the second fixing plate 7.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
