Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing molds, specifically a forging mold for efficient dual-cavity forming of forged aluminum alloy runner plates. Background Technology

[0002] Aluminum alloy runner plates are used in vehicle thermal management systems and are complex and critical components. They are difficult to form using die-casting molds, and die-casting can result in insufficient local structural strength of the aluminum alloy runner plate. Therefore, forging molds can meet the requirements. However, since the aluminum alloy runner plate needs to generate flash in all directions during the forming process, the design of the forging mold is particularly important. It is necessary to prevent interference or other issues during the flash generation process. In addition, most current forging molds use a single-cavity structure, which is detrimental to the production efficiency of aluminum alloy runner plates and results in a lot of material waste. Summary of the Invention

[0003] This invention provides a forging die for efficient dual-cavity forming of forged aluminum alloy flow channel plates, which solves the problems of low processing efficiency and inability to effectively eliminate flash interference in existing forging dies.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a forging die for efficient dual-cavity forming of forged aluminum alloy flow channel plates, comprising an upper die and a lower die arranged vertically. A pre-forging upper protrusion forming platform and a final forging upper protrusion forming platform are arranged side-by-side on the lower side of the upper die. A pre-forging lower protrusion forming platform and a final forging lower protrusion forming platform are arranged side-by-side on the upper side of the lower die. An unobstructed flash gap is formed between the upper die and the lower die around the pre-forging upper protrusion forming platform, the final forging upper protrusion forming platform, the pre-forging lower protrusion forming platform, and the final forging lower protrusion forming platform. A pre-forging upper forming structure and a final forging upper forming structure are respectively arranged side-by-side on the pre-forging upper protrusion forming platform and the final forging lower protrusion forming platform. The die platform is equipped with pre-forging lower forming concave cavities and final forging lower forming concave cavities arranged side by side. Upper clamping forming grooves are provided between the pre-forging upper forming structures and between the final forging upper forming structures. Lower clamping forming grooves are provided between the pre-forging lower forming concave cavities and between the final forging lower forming concave cavities. The raw material is forged by impacting it from top to bottom using the pre-forging upper protruding forming platform, the final forging upper protruding forming platform, the pre-forging lower protruding forming platform, and the final forging lower protruding forming platform. The unobstructed flash gap adopts a structure that is open on all four sides, which does not interfere with the flash generation process and makes the flash less prone to breakage, preventing secondary damage to the forging body. Moreover, both pre-forging and final forging use a dual-cavity forming structure, resulting in high production efficiency and improved raw material utilization.

[0005] Preferably, the outer periphery of the pre-forging upper protruding forming platform, the final forging upper protruding forming platform, the pre-forging lower protruding forming platform, and the final forging lower protruding forming platform are inclined surfaces with an inclination angle of -°. This can effectively prevent the flash deformation of the parts, which would lead to quality problems such as the flash being crushed during the forging process. It also provides sufficient space for the robot arm to hold the parts, greatly improving the stability of the robot arm clamp and increasing the transfer cycle of the parts after clamping.

[0006] Preferably, the area of ​​the lower clamping structure forming groove is larger than the area of ​​the upper clamping structure forming groove, so that the lower clamping structure forming groove has the function of storing and positioning materials, and can form a positioning and clamping structure in pre-forging and final forging, which is beneficial for the robot arm to clamp and move the material.

[0007] Preferably, the two pre-forging upper forming structures, the two final forging upper forming structures, the two pre-forging lower forming concave cavities, and the two final forging lower forming concave cavities are all staggered to improve material utilization and facilitate material flow.

[0008] Preferably, the upper and lower dies are provided with multiple heating tubes arranged laterally in a staggered manner inside, which can uniformly heat the upper and lower dies and is beneficial to forging accuracy.

[0009] Preferably, the lower die is provided with multiple ejector rods around the pre-forging lower protrusion forming platform and the final forging lower protrusion forming platform. During demolding, the ejector rods can push against the flash to smoothly eject the forging body.

[0010] Preferably, the lower die has guide grooves at its four corners, and the upper die has guide bosses at its four corners that match and interlock with the guide grooves, so as to provide precise guidance for the upper and lower die forging.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The forging die integrates the final forging cavity and the pre-forging cavity into one die, eliminating the need for semi-finished product turnover. It uses the upper protruding forming platform for pre-forging, the upper protruding forming platform for final forging, the lower protruding forming platform for pre-forging, and the lower protruding forming platform for final forging to impact and forge the raw material. The unobstructed flash gap adopts a structure that runs through all four sides, which is mainly used as an escape channel for flash. It does not interfere with the flash generation process, and the flash is not easy to break, preventing secondary damage to the forging body. Moreover, both pre-forging and final forging adopt a dual-cavity forming structure, which has high production efficiency and improves the utilization rate of raw materials.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 1-3 As shown, to address the problem of low processing efficiency and inability to effectively eliminate flash interference in existing forging dies, this invention provides an embodiment: a forging die for high-efficiency dual-cavity forming of forged aluminum alloy runner plates, comprising an upper die 1 and a lower die 2 arranged vertically. The lower side of the upper die 1 is provided with a pre-forging upper protrusion forming platform 12 and a final forging upper protrusion forming platform 14 arranged side-by-side. The upper side of the lower die 2 is provided with a pre-forging lower protrusion forming platform 4 and a final forging lower protrusion forming platform 5 arranged side-by-side. An unobstructed flash gap 3 is formed between the upper die 1 and the lower die 2 around the pre-forging upper protrusion forming platform 12, the final forging upper protrusion forming platform 14, the pre-forging lower protrusion forming platform 4, and the final forging lower protrusion forming platform 5. The pre-forging upper protrusion forming platform 12 and the final forging upper protrusion forming platform 14 are respectively provided with a pre-forging upper forming structure 16 and a final forging upper forming structure 15 arranged side-by-side. The pre-forging lower protruding forming platform 4 and the final forging lower protruding forming platform 5 are respectively provided with pre-forging lower forming concave cavities 6 and final forging lower forming concave cavities 8 arranged side by side. The upper forming structure 16 of the pre-forging upper forming structure 16 and the upper forming structure 15 of the final forging upper forming structure are provided with upper clamping structure forming grooves 13. The lower clamping structure forming grooves 17 of the pre-forging lower forming concave cavities 6 and the final forging lower forming concave cavities 8 are provided with lower clamping structure forming grooves 17. The raw material is forged by impacting it from top to bottom using the pre-forging upper protruding forming platform 12, the final forging upper protruding forming platform 14, the pre-forging lower protruding forming platform 4 and the final forging lower protruding forming platform 5. The unobstructed flash gap 3 adopts a structure that is open on all four sides, which does not interfere with the flash generation process and the flash is not easy to break, thus preventing secondary damage to the forging body. Moreover, both pre-forging and final forging adopt a double-cavity forming structure, which has high production efficiency and improves the utilization rate of raw materials.

[0020] Among them, the pre-forging upper forming structure 16 and the final forging upper forming structure 15 can be structures that protrude from the pre-forging upper protruding forming platform 12 and the final forging upper protruding forming platform 14, respectively. During forging, they can first contact the raw material and play a role in positioning and blocking the material. The pre-forging lower forming concave cavity 6 and the final forging lower forming concave cavity 8 adopt concave cavity structures, which can guide and restrict the flow of raw material and have a good material storage and blocking effect. The interaction between the upper forming structure and the lower forming concave cavity can effectively prevent the raw material from folding. In addition, the two pre-forging upper forming structures 16, the two final forging upper forming structures 15, the two pre-forging lower forming concave cavities 6, and the two final forging lower forming concave cavities 8 are all staggered, which improves material utilization and facilitates material flow.

[0021] In this embodiment, as Figure 1-3 As shown, the outer periphery of the pre-forging upper protruding forming platform 12, the final forging upper protruding forming platform 14, the pre-forging lower protruding forming platform 4, and the final forging lower protruding forming platform 5 are inclined surfaces. The inclination angle of the inclined surfaces is 40-50°, which can effectively prevent the flash deformation of the parts, thus preventing the quality problem of the flash being crushed during the forging process. It also provides sufficient space for the robot arm to hold the parts, greatly improving the stability of the robot arm clamp and increasing the transfer cycle of the parts after clamping.

[0022] In some embodiments, such as Figure 2-3 As shown, the area of ​​the lower clamping structure forming groove 17 is larger than the area of ​​the upper clamping structure forming groove 13, so that the lower clamping structure forming groove 17 has the function of storing and positioning materials, and can form a positioning and clamping structure in pre-forging and final forging, which is beneficial for the robot arm to clamp and move around.

[0023] To effectively heat the upper die 1 and lower die 2, multiple heating tubes 9 are arranged laterally and alternately inside the upper die 1 and lower die 2, which can uniformly heat the upper die 1 and lower die 2 and is beneficial to forging accuracy. At the same time, multiple ejector rods 7 are arranged around the pre-forging lower protrusion forming platform 4 and the final forging lower protrusion forming platform 5 on the lower die 2. During demolding, the ejector rods 7 can push against the flash to smoothly eject the forging body.

[0024] like Figure 2-3 As shown, the lower die 2 is provided with guide grooves 10 at the four corners, and the upper die 1 is provided with guide bosses 11 at the four corners that match and insert into the guide grooves 10, so as to accurately guide the upper and lower forging of the upper die 1 and the lower die 2.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0027] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
