Description

Technical Field

[0001] The present application relates to the technical field of die-casting mold equipment, and particularly to an automotive wire harness bracket and its manufacturing mold. Background Art

[0002] In the modern production process, the requirements for the accuracy and efficiency of frame manufacturing are increasing day by day. Especially for parts such as automotive wire harness brackets that integrate storage, the complexity of their shapes and the fineness of processing have become the key factors determining product quality. Such parts involve multiple processing steps, including bending, curling, punching, and folding. Most traditional manufacturing equipment can only perform simple cutting and rough shape die-casting. For parts with complex shapes such as automotive wire harness brackets, molds are usually required for preliminary shape die-casting. Although this step can form the blank of the part, it only completes a part of the entire processing flow. Next, workers still need to use various equipment to perform subsequent processing on the blank, such as opening holes, bending, and folding. This processing and manufacturing method has obvious efficiency problems. Due to the dispersion of processing steps, different equipment and workers are required, resulting in a long and complex production process. This not only reduces production efficiency but also may lead to unstable product quality due to human factors. In addition, using multiple pieces of equipment also means that the enterprise needs to invest more funds in purchasing equipment, increasing the upfront cost investment. Summary of the Invention

[0003] In order to be able to directly process and produce automotive wire harness brackets with complex shapes, eliminating the steps of using molds and subsequent manual processing, the present application provides an automotive wire harness bracket and its manufacturing mold.

[0004] An automotive wire harness bracket provided by the present application adopts the following technical solution, including a frame body. The frame body is folded to form a folding part. The folding part includes an upper folding part, a lower folding part, and an extended folding part. Long strip-shaped grooves are formed on the upper folding part and the lower folding part to form grooves. Two curling parts are bent downward on the frame body. A bending part is bent at the middle position of the frame body. A plurality of through holes are also formed on the frame body to form fixing holes. One fixing hole is opened at each end of the upper folding part, the lower folding part, and the extended folding part. A notch is opened at the end of the curling part to form a wire routing groove.

[0005] By adopting the above technical solutions, the automotive wire harness bracket includes structural components such as an upward folding part, a downward folding part, and an extended folding part. The arrangement of these folding parts enables the bracket to better adapt to the complex wire layout inside the vehicle. The long strip-shaped groove design can effectively fix and organize the wires, preventing them from getting tangled and misaligned. In addition, the through holes on the bracket body, namely the fixing holes, not only enhance the structural strength of the bracket body but also facilitate the fixing of the wires. The arrangement of the curling part and the wire groove formed by the notch at its end further optimizes the layout and routing of the wires.

Through grooves are correspondingly formed at the bottoms of the first cutting block, the second cutting block, and the third cutting block to form a blanking groove. The first cutting block and the second cutting block are spaced apart. The first cutting block is arranged at the middle position of the mold, and the second cutting block and the third cutting block are arranged at the discharging end of the mold.

[0013] By adopting the above technical solutions, the specific shape of each cutting block can be customized according to actual needs to better adapt to the contour of the frame. Such a design improves the cutting accuracy and enhances the applicability of the mold. The multi-point setting of the cutting pads ensures the stability of the cutting process and the cutting quality. The design of the through groove and the blanking groove of the cutting block enables the cut material to fall smoothly, facilitating subsequent collection and processing.

[0014] In a specific feasible embodiment, the bending mechanism includes a bending block fixedly arranged on the moving mold and a bending groove fixedly arranged on the fixed mold. An forming arc surface is arranged in the bending groove, and an arc surface is formed at one end of the bending block corresponding to the forming arc surface to form a bending arc surface.

[0015] By adopting the above technical solutions, the bending block fixed on the moving mold cooperates with the bending groove on the fixed mold. Through the interaction between the forming arc surface in the bending groove and the bending arc surface on the bending block, precise bending of the material is achieved. This design can ensure the bending accuracy and improve the working efficiency.

[0016] In a specific feasible embodiment, the locking mechanism includes a plurality of locking blocks. The locking blocks are rotatably arranged on the outer edge of the mold. The body of the locking block is set in a cylindrical shape, and a flat surface and a groove surface are formed at both ends of the locking block to form an unlocking surface and a locking groove respectively.

The second folding component includes an upper folding block and a lower folding block. The upper folding block is slidably arranged on the moving mold, and the lower folding block is slidably arranged on the fixed mold. Folding surfaces for guiding are formed on opposite sides of the upper and lower folding blocks. The third folding component is used to fold the extension folding part near the middle position of the frame body. The third folding component includes a folding bottom block fixedly arranged on the fixed mold. An arc surface identical to the extension folding part is arranged at the top of the folding bottom block. The third folding component further includes a first folding segment block and a second folding segment block arranged on the moving mold.

The first folding segment block and the second folding segment block are arranged in a splicing manner. A sliding groove is formed on the first folding segment block, and a sliding block matching the sliding groove is formed on the second folding segment block.

[0019] By adopting the above technical solution, the first folding component realizes the preliminary folding of the material through the cooperation of the fixed block and the folding block. The folding surface design of the upper folding block and the lower folding block of the second folding component plays an accurate guiding role, ensuring the accuracy of folding.

The curling mechanism is composed of a first curling block and a second curling block, both of which are arranged on the moving mold. The first curling block is placed near the middle position of the frame body, which is beneficial for its cooperation with the curling die core during work to provide the initial curling force for the material. The second curling block is arranged away from the middle position of the frame body to ensure uniform curling during the curling process.

[0022] An arc surface is formed on the curling die core, enabling the material to be smoothly curled into the required shape when passing through.

[0023] In a specific feasible implementation, a positioning mechanism is also slidably arranged on the moving die. The positioning mechanism includes a positioning ejector pin module, which is composed of a plurality of independent positioning ejector pins distributed on the moving die.

This avoids the position deviation of the processed profile caused by tool cutting during mold closing.

[0047] Referring to Figure 5 , the cutting mechanism includes cutting blocks 531 with various different shapes. In the embodiment of the present application, the number of cutting blocks 531 is set to ten according to the external shape of the automotive wire harness bracket. The shape of each cutting block 531 is set according to a section of the contour shape of the frame body 91. The ten irregularly shaped cutting blocks 531 sequentially form and cut the general shape of the automotive wire harness bracket. The wire routing groove 97 is directly cut and formed by the cutting mechanism. The cutting blocks 531 are all fixedly arranged on the moving die 6, and a ejector pin hole is opened on each cutting block 531. The cutting mechanism further includes cutting pads 532. The cutting pads 532 are fixedly arranged on the fixed die 5. There are a plurality of cutting pads 532, and the plurality of cutting pads 532 are respectively set as blocks with different sizes. The material hardness of the cutting pads 532 is greater than that of the fixed die 5, so as to cooperate with the cutting blocks 531 to cut the processed profile and protect the fixed die 5 from being damaged. The ten different cutting blocks 531 are divided into two groups according to the influence on the finished product shape. Two irregularly shaped through grooves are formed above and below the processed material after cutting to form the first contour groove 81 and the second contour groove 82. The first contour groove 81 and the second contour groove 82 are used to form the external contour shape of the frame body 91, and the first contour groove 81 and the second contour groove 82 are not connected to each other. The four cutting blocks 531 near the upper part are arranged in sequence according to the processing direction, and the first contour groove 81 passes through four cutting operations of the four cutting blocks 531 respectively. Each cutting block 531 corresponds to one shape of the first contour groove 81, and the four cutting grooves are finally spliced to form the first contour groove 81. The second contour groove 82 is composed of six cutting blocks 531 near the lower part. The six cutting blocks 531 are arranged and distributed according to the mold processing direction. The formation method of the second contour groove 82 is the same as that of the first contour groove 81, and is formed by splicing the grooves formed by the corresponding six cutting blocks 531 after cutting. The distributed cutting blocks 531 can enhance the hardness of a single cutting block 531 and flexibly adapt to complex cutting shapes. As an easily worn component, when one of the cutting blocks 531 is damaged, it can be replaced conveniently, thereby reducing the overall maintenance cost of the mold equipment.

[0048] Referring to Figure 9, the cutting mechanism further includes three cutting blocks arranged at both ends of the mold, namely the first cutting block 533, the second cutting block 534, and the third cutting block 535. The three cutting blocks are all arranged on the moving mold 6. Through grooves are correspondingly arranged at the bottoms of the first cutting block 533, the second cutting block, and the third cutting block 535 to form a blanking groove 5331. Cutting tools for cutting are provided on each cutting block. The first cutting block 533 and the second cutting block 534 are spaced apart. The first cutting block 533 is arranged at the middle position of the mold, and the second cutting block 534 and the third cutting block 535 are arranged at the discharging end of the mold. The cutting blocks are used to cut the corner materials of the frame body 91 before the film is taken out. Since the latter half of the mold is set for folding and curling the frame body 91, the mold itself has a good positioning effect on the frame body 91 during the folding and curling process. Therefore, setting the first cutting block 533 at the middle position of the mold can reduce the number of positioning ejector pin modules 556 used, playing a role in cost saving. The second cutting block and the third cutting block 535 are used for the cutting operation of the processed frame body 91 before taking out the mold.

[0049] Refer to Figure 10 and Figure 11 , the bending mechanism includes a bending block 541 fixedly arranged on the moving mold 6 and a bending groove 542 fixedly arranged on the fixed mold 5. The bending groove 542 is set as a groove opened downward on the fixed mold 5. A forming arc surface 5421 is arranged in the bending groove 542. The forming arc surface 5421 is set as an arc surface connecting the top of the fixed mold 5 and the bottom of the bending groove 542, and the forming arc surface 5421 is set as a convex arc surface. The bending block 541 is set as a block shape. A thimble groove is opened on the bending block 541. An arc surface is opened at one end of the bending block 541 corresponding to the forming arc surface 5421 to form a bending arc surface 5411. The bending arc surface 5411 is set as a concave arc surface, and the bending arc surface 5411 is matched with the forming arc surface 5421. The shapes of the bending arc surface 5411 and the forming arc surface 5421 are set according to the processing requirements of the frame body 91. The bending block 541 is used to perform bending processing on the bending part 95 during mold closing.

[0050] Refer to Figure 12 and Figure 13, the folding mechanism includes a first folding component 551, a second folding component 552, and a third folding component 553. The first folding component 551 includes a fixed block 5511 and a folding block 5512. The fixed block 5511 and the folding block 5512 are fixedly arranged on the moving mold 6. One end of the fixed block 5511 close to the fixed mold 5 is provided with a fixed groove, which is matched with the long groove portion 93. The fixed block 5511 fixes the frame 91 through the fixed groove, avoiding excessive local deformation area of the frame 91 during folding. The folding block 5512 is arranged adjacent to the fixed block 5511, and a folding protrusion is provided on the folding block 5512. The first folding component 551 further includes a folding groove corresponding to the folding protrusion. During mold closing, the folding protrusion can be inserted into the folding groove. Thimble holes are provided on both the fixed block 5511 and the bending block, and the fixed block 5511 and the bending block act synchronously. The first folding component 551 is used to fold and form the outer edges of the upper folding portion 922, the lower folding portion 921, and the extended folding portion 923.

[0051] The second folding component 552 is used to fold and form the positions of the upper folding portion 922 and the lower folding portion 921 close to the edge of the frame 91. The second folding component 552 includes an upper folding block 5521 and a lower folding block 5522. The upper folding block 5521 is slidably arranged on the moving mold 6, and the lower folding block 5522 is slidably arranged on the fixed mold 5. Folding surfaces 5523 for guiding the upper folding portion 922 and the lower folding portion 921 are provided on the opposite sides of the upper and lower folding blocks 5522. The upper folding block 5521 and the lower folding block 5522 are customized according to the shapes of the upper folding portion 922 and the lower folding portion 921. In order to protect the frame 91 from large bending stresses, the second folding component 552 is arranged after the first folding component 551 is processed. The spaced segmented arrangement can avoid damage to the frame 91 during die casting and reduce the rejection rate of the frame 91. Since there are many processing steps in the middle part of the frame 91, in order to avoid the first folding component 551 and the second folding component 552 from folding the frame 91, first fold the outer edges of the upper folding portion 922, the lower folding portion 921, and the extended folding portion 923, and then fold and form the positions of the upper folding portion 922 and the lower folding portion 921 close to the middle of the frame 91.

[0052] The third folding component 553 is used to fold the extension folding part 923 near the middle position of the frame body 91. The third folding component 553 includes a folding bottom block 5531 fixedly arranged on the fixed mold 5. The top of the folding bottom block 5531 is provided with an arc surface the same as that of the extension folding part 923. The third folding component 553 further includes a first folding segment block 5532 and a second folding segment block 5534 arranged on the moving mold 6. Thimble reserved holes are provided on both the first folding segment block 5532 and the second folding segment block 5534. The bottoms of the first folding segment block 5532 and the second folding segment block 5534 are both provided with arc surfaces that cooperate with the folding bottom block 5531. The first folding segment block 5532 and the second folding segment block 5534 are arranged in a spliced manner, that is, a sliding groove 5533 is provided on the first folding segment block 5532, and a sliding block 5535 that cooperates with the sliding groove 5533 is provided on the second folding segment block 5534. When die-casting the extension folding part 923, the first folding segment block 5532 is first driven by a thimble for die-casting, and then the second folding block 5512 is die-cast. The settings of the sliding groove 5533 and the sliding block 5535 play a guiding role, enabling the second folding segment block 5534 to accurately continue die-casting the extension folding part 923 along the edge of the first folding segment block 5532.

[0053] Refer to Figure 14 , the curling mechanism includes a first sub-curling block 554, a second sub-curling block 5542 and a curling die core 5543. The first sub-curling block 554 and the second sub-curling block 5542 are arranged on the moving mold 6. The first sub-curling block 554 is arranged near the middle position of the frame body 91, and the second sub-curling block 5542 is arranged away from the middle position of the frame body 91. The curling die core 5543 is fixedly arranged on the fixed mold 5. An arc surface is provided on the curling die core 5543. The first sub-curling block 554 and the second sub-curling block 5542 are driven by thimbles. Curling arc surfaces 5541 are provided on both the first sub-curling block 554 and the second sub-curling block 5542. The curling arc surfaces 5541 provided on the first sub-curling block 554 and the second sub-curling block 5542 jointly form an arc surface the same as that of the curling die core 5543. The first sub-curling block 554 and the second sub-curling block 5542 adopt different die-casting sequences when the mold is closed, that is, the second sub-curling block 5542 is die-cast first, and then the second sub-curling block 5542 is die-cast again, so as to cooperate with the curling die core 5543 to form a complete curling effect on the frame body 91.

[0054] Refer to Figure 4, the locking mechanism is arranged at the edge of the mold. The locking mechanism includes a plurality of locking blocks 555. The locking blocks 555 are rotatably arranged at the outer edge of the mold. The body of the locking block 555 is cylindrical. A flat surface and a groove surface are formed at both ends of the locking block 555 to form an unlocking surface 5551 and a locking groove 5552 respectively. An irregular protrusion is arranged at the top of the locking block 555 to form a transmission tooth 5553. The transmission tooth 5553 meshes with a rotating ejector pin arranged in the mold. The transmission tooth 5553 is set as a half tooth, which can achieve the technical effect of only rotating 180 degrees at a time, so that the locking block 555 can be switched between the unlocking surface 5551 and the locking groove surface. When the unlocking surface 5551 of the locking block 555 is aligned with the frame 91, the frame 91 can continue to feed through the unlocking surface 5551. When the locking surface of the locking block 555 is aligned with the frame 91, the frame 91 extends into the locking groove 5552. When the mold is closed, the locking groove 5552 presses down to increase the frictional force of pressing down on the frame 91, thereby playing a locking role.

[0055] The implementation principle of the embodiment of this application is as follows: After the mold is started, through the transmission mechanism of the mold, including a feeding conveyor belt 71 and a discharging conveyor belt 72, which are responsible for the transmission of the processed profiles. The transmission mechanism gradually pushes and feeds the processed profiles according to the processing steps. The locking block 555 and the positioning ejector pin module 556 first perform locking and positioning, and the moving mold 6 and the fixed mold 5 perform die casting on the processed profiles, and perform processing and forming such as grooving, punching, bending, curling and folding on the frame 91.

[0056] The grooving mechanism realizes the die casting of the long groove part 93 through the cooperation of the long strip module 512 and the long groove module 51, and the drive of the ejector pin module 311. The punching mechanism processes the positioning hole 83 and the slot hole of the frame 91. After the cutting mechanism cuts the contour shape of the frame 91, the bending mechanism bends the middle part of the frame 91 through the cooperation of the bending block 541 and the bending groove 542. The folding mechanism performs upward and downward folding operations on the edge and the middle position of the frame 91 respectively. The curling mechanism realizes the curling processing of the frame 91.

[0057] The above are all the preferred embodiments of this application. The protection scope of this application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
