[0001] The utility model relates to the technical field of molds, in particular to an inclined wedge flattening mold. Background Art

[0002] In modern manufacturing, inclined wedge flattening dies are widely used in the forming processing of various metal and non-metal materials, especially in the fields of automobile manufacturing, home appliance manufacturing and electronic component production. The inclined wedge flattening dies flatten the edges or specific parts of the workpiece by precisely controlling the movement of the punch to meet the design requirements and quality standards of the product.

[0003] At present, the traditional wedge flattening mold structure design has some limitations. Especially when processing products that require beveled surface flattening, the wedge flattening space of the mold is very limited. In the limited space, the stability area of ​​the wedge pressing material is small and cannot provide a large enough pressing force, resulting in poor pressing effect. It causes the product to be easily deformed during the flattening process, affecting the final molding quality and consistency.

[0004] In order to solve the above problems, the utility model proposes a new type of inclined wedge flattening die, which uses a transmission rod to promote the movement of the inclined wedge to meet the requirements of large pressing surface and high strength. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1-Figure 5, a wedge flattening mold, including a mold pressing plate 1, a lower mold forming male 2, a flattening punch 3, a punch fixing block 4, a first driving block 5, a wear-resistant plate 6, a first input block 7, a plunger punch 8, a guide operating block 9, a second driving block 10, a transmission rod 11, a wear-resistant block 12, a second input block 13, a supported knife block 14 and a mounting base 15, wherein the mold pressing plate 1 is responsible for pressing the workpiece, while the lower mold forming male 2 serves as a support for the workpiece and provides it with a basic shape for forming; the plunger punch 8 is installed on the punch slider, and is provided with a guide support by the supported knife block 14 to ensure that it does not deviate from the predetermined path during the descent process, and after the inclined surface of the plunger punch 8 contacts the second driving block 10, it pushes the second driving block 10 to slide along the wear-resistant block 12; the wear-resistant block 12 is fixed in the second input block 13, providing the necessary sliding surface and support; the second driving block 10 is connected to the first driving block through the transmission rod 11 5. When the second driving block 10 slides, the force is transmitted to the first driving block 5 through the transmission rod 11, wherein the transmission rod 11 is guided to move by the guide operating block 9, thereby ensuring the straightness and stability of the transmission rod 11 during the movement; the first driving block 5 is connected to the flattening punch 3 and its punch fixing block 4, and the flattening punch 3 and the punch fixing block 4 can slide along the inclined surface of the wear-resistant plate 6 to the workpiece to perform flanging and flattening. When subjected to the force from the transmission rod 11, the flattening punch 3 and the punch fixing block 4 are driven to slide along the inclined surface of the wear-resistant plate 6, so that the flattening punch 3 uses its special shape and angle to perform flanging and flattening on the workpiece; the wear-resistant plate 6 is fixed in the first entry block 7 to ensure stability and reduce wear during the sliding process; the mounting base 15 is the basic structural part of the entire mold, which is used to install and fix all the above-mentioned components to ensure the stability and accuracy of the entire mold structure.

[0026] First, the workpiece is placed on the lower die forming male 2, and the die pressing plate 1 presses the workpiece from above. At this time, a material thickness gap is maintained between the die pressing plate 1 and the lower die forming male 2. Then, the insert punch 8 moves downward with the punch slider. When the inclined surface of the insert punch 8 contacts the second drive block 10, the second drive block 10 transmits the force to the first drive block 5 through the transfer rod 11, and the transfer rod 11 slides in the guide operating block 9 to ensure that the force transmission is accurate. After the first drive block 5 is acted upon by the transfer rod 11, it drives the flattening punch 3 and the punch fixing block 4 to slide along the inclined surface of the wear-resistant plate 6. As the flattening punch 3 slides along the inclined surface, the flattening punch 3 gradually approaches the workpiece and applies pressure to realize the flanging and flattening action of the workpiece.

[0027] Example 2: Based on Example 1, please refer to Figure 6 and Figure 7, also includes a fixing frame 16, a safety grating 17, a prompter 18, a protective cover 23 and an isolation plate 26. The fixing frame 16 is arranged on the four sides of the mounting base 15, and the safety grating 17 is installed inside the fixing frame 16. An invisible light curtain can be formed between the safety gratings 17 to detect whether there is a person's hand reaching into the mold working area. In addition, an isolation plate 26 is provided between the two fixing frames 16 to separate the operating area and the safety area to improve operational safety. The prompter 18 is provided outside the fixing frame 16. When the safety grating 17 detects an abnormal situation, the prompter 18 will emit a continuous alarm sound to warn, thereby ensuring the safety of production and operation. A protective cover 23 is also provided outside the prompter 18 to protect the prompter 18 from external physical damage and environmental influences.

[0028] See also Figure 6 and Figure 8 , also includes a fixed seat 19, a guide rod 20, a buffer plate 21, a shock-absorbing spring 22, a protective pad 24 and a placement frame 25. The placement frame 25 is arranged on the side of the mold pressing plate 1 for storing tools and auxiliary materials for easy access by operators, and the fixed seat 19 is arranged on two opposite edges of the mounting base 15. The fixed seat 19 is fixedly connected to the guide rod 20, and a buffer plate 21 is slidably arranged on the guide rod 20. One end of the shock-absorbing spring 22 is connected to the buffer plate 21, and the other end is connected to the fixed seat 19. Through the cooperation of the buffer plate 21 and the shock-absorbing spring 22, the impact force can be absorbed and dispersed during mold operation, thereby reducing damage to the mold and workpiece. In addition, a protective pad 24 is provided on the surface of the buffer plate 21 to reduce friction and wear between the buffer plate 21 and the mold.

[0029] When the mold gradually closes for the flattening operation, the buffer plate 21 is squeezed by the upper mold and moves downward along the guide rod 20 to compress the shock-absorbing spring 22. The shock-absorbing spring 22 absorbs the impact force generated by the mold through elastic deformation, effectively reducing the impact on the mold and workpiece, and improving the stability and reliability of the mold. When the mold completes a flattening operation and starts to return, the shock-absorbing spring 22 returns to its original state, pushing the buffer plate 21 upward to the initial position, preparing for the next flattening operation.
