Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a round bar stamping mold. Background Technology

[0002] Molds play a crucial role in product processing, transforming raw materials into the desired product through forming processes. With rapid economic development and increasingly diversified market demands, requirements for production cycles are becoming more stringent, while quality standards are constantly rising, especially in small-batch and even single-piece production. In the application of round bar stamping dies, to improve production efficiency, welding technology is often used to connect multiple dies together to achieve multi-output production from a single die. However, this welding method has a significant problem: it cannot guarantee that the longitudinal height of the dies is completely consistent. Therefore, when performing multi-output production from a single die, it is difficult to ensure the integrity and consistency of the output. Furthermore, since the dies are connected by welding, if one die is damaged, the entire set of dies often needs to be replaced, which undoubtedly increases production costs and maintenance difficulty.

[0003] Therefore, this application develops a round bar stamping die to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of this utility model is to provide a round bar stamping die to solve the problem in the prior art where, after realizing the function of one die for multiple outputs, one die is damaged and cannot be replaced.

[0005] The technical solution of this utility model is: a round bar stamping die, comprising: an upper die and a lower die, wherein the upper die is located above the lower die, the upper die includes an upper die base and an upper template, the lower die includes a lower die base and a lower template, and both the upper template and the lower template are provided with forming cavities at their respective close ends, and the upper template and the lower template are detachably connected to the upper die base and the lower die base, respectively.

[0006] Preferably, the upper mold base and the lower mold base are provided with a plurality of mounting holes, and the ends of the upper template and the lower template that are far apart from each other are provided with connecting holes corresponding to the mounting holes. The upper mold base and the upper template, and the lower mold base and the lower template are fixedly connected by fasteners passing through the mounting holes and the corresponding connecting holes.

[0007] Preferably, the upper and lower templates are brought close together at their adjacent ends, so that the two forming cavities cooperate to form a stamped product.

[0020] The present invention will be further described in detail below with reference to specific embodiments:

[0021] like Figure 1 As shown, a round bar stamping die includes an upper die 1 and a lower die 2, wherein the upper die 1 is located above the lower die 2. The upper die 1 includes an upper die base 11 and an upper template 12, and the lower die 2 includes a lower die base 21 and a lower template 22. A forming cavity 3 is provided at one end of the upper template 12 and the lower template 22 that are close to each other. The upper die base 11 is a component that supports and fixes the upper template 12, and the lower die base 21 also plays a supporting and fixing role. When the upper die 1 and the lower die 2 are closed, the forming cavity 3 extrudes the raw material into the required shape. A support seat 7 is provided at the connection between the upper template 12 and the lower template 22, which provides stable support for the die.

[0022] In this embodiment, as Figure 2 , Figure 4 As shown, the upper mold base 11 and the lower mold base 21 are provided with multiple mounting holes 4, while the upper template 12 and the lower template 22 are provided with connecting holes 5 corresponding to the mounting holes 4 at the positions where they contact the corresponding upper mold base 11 and lower mold base 21. The fasteners pass through at least one set of mounting holes 4 and connecting holes 5 to connect and fix the upper mold base 11 and the upper template 12, and the lower mold base 21 and the lower template 22, so that the upper mold base 11 and the upper template 12, and the lower mold base 21 and the lower template 22 are detachably connected. The fasteners include, but are not limited to, screws, bolts, and screws. The detachable connection design allows each component of the mold to be replaced or adjusted individually without replacing the entire mold, which helps to reduce the mold maintenance cost and improve the mold's adaptability to different products. Since each component of the mold can be easily disassembled, it is easier to inspect and repair damaged or worn parts of the mold, thereby extending the mold's service life. At the same time, by adjusting the position and number of mounting holes 4 and connecting holes 5, the structure of the mold can be optimized to make it more compact and efficient, reducing the mold's footprint and weight, and lowering production costs.

[0023] Furthermore, such as Figures 2-3As shown, the upper template 12 and the lower template 22 are brought close together at their adjacent ends, so that the two forming cavities 3 cooperate to form a stamped product. The upper template 12 and the lower template 22 form a template assembly 6. By arranging multiple template assemblies 6 radially along the upper mold base 11, multiple stamping positions can be formed, thereby producing multiple products at the same time, significantly improving production efficiency. At the same time, it can be flexibly adjusted according to production needs. By increasing or decreasing the number of stamping positions, it can adapt to different scale production tasks. Furthermore, since the template assembly 6 is independent, when a stamping position malfunctions or needs maintenance, the template assembly 6 can be disassembled and replaced individually without affecting the normal operation of other stamping positions.

[0024] To improve the stability of the mold during the stamping process, the upper mold base 11 includes a first connecting part 111 and a first pressure-bearing part 112, and the lower mold base 21 includes a second connecting part 211 and a second pressure-bearing part 212. The first connecting part 111 and the second connecting part 211 are respectively connected to the corresponding upper mold plate 12 and lower mold plate 22. The design of the first pressure-bearing part 112 and the second pressure-bearing part 212 enables the mold to more effectively disperse and bear pressure when subjected to pressure, thereby ensuring the stability and safety of the mold. The reasonable design of the pressure-bearing part and the connecting part can reduce the wear and deformation of the mold during use, thereby extending the service life of the mold. The diameter of the first pressure-bearing part 112 is larger than the diameter of the first connecting part 111, and the diameter of the second pressure-bearing part 212 is larger than the diameter of the second connecting part 211. By increasing the diameter of the pressure-bearing part, its bearing area can be increased, thereby dispersing the pressure, reducing the pressure value per unit area, enhancing the overall pressure-bearing capacity of the mold, and also reducing the deformation and wear of the mold during the stamping process.

[0025] Furthermore, the lower die plate 22 includes an upper part 221, a middle part 222, and a lower part 223. The upper part 221 is connected to the lower die base 21. The thickness of the upper part 221 and the lower part 223 is greater than that of the middle part 222, which allows the die to more effectively disperse stress when subjected to the pressure during the stamping process, reducing the risk of deformation and damage. The thickened upper part 221 and the lower part 223 can provide a more stable support surface, which helps the die to be accurately positioned in the machine.
