Description

Technical Field

[0001] This utility model relates to the technical field of forging dies, and in particular to a forming die for a heat pipe bracket. Background Technology

[0002] As a key component for thermal management in electronic devices, the manufacturing process of heat pipe brackets has a significant impact on product performance and cost. Currently, heat pipe brackets are commonly manufactured using forging technology. This technology applies pressure to a metal blank using a mold, causing it to undergo plastic deformation to obtain the desired product shape.

[0003] Traditional forging dies typically consist of a lower die with a groove and an upper die with a protrusion. During forging, the upper die's punch engages with the lower die's cavity, forging the blank placed within the cavity. However, for products with complex shapes, especially those with extended sides, existing die designs have some limitations:

[0004] High mold costs: If the extended portion of the product is to be included in the die for forging, the area and depth of the die need to be increased. This not only increases the manufacturing cost of the mold but also extends the processing cycle.

[0005] Limited forging efficiency: Traditional die designs may not be able to effectively handle forging of complex shapes, resulting in low production efficiency.

[0006] Limited product functionality: When forming heat pipe supports with multiple functional structures (such as clamping bosses, bosses of different heights, clearance areas, etc.), existing molds may require more complex multi-process or multi-mold combinations, increasing production complexity.

[0007] Therefore, existing forging dies for heat pipe supports suffer from high manufacturing costs, low efficiency, and insufficient design flexibility when faced with products with complex structures and multifunctional requirements. There is an urgent need for a die structure that can effectively solve these problems. Utility Model Content

[0008] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0009] This utility model provides a forming mold for a heat pipe bracket, including an upper mold plate and a lower mold plate that correspond to each other. The upper mold plate has a punch at one end facing the lower mold plate, and the lower mold plate has a die at one end facing the upper mold plate. During forging, the punch and the die plate are joined together, so that the punch is inserted into the die plate to form the forming area of ​​the heat pipe bracket. On the side of the die plate, a specific limiting structure is used to maintain a preset height gap between the upper mold plate and the lower mold plate, thereby forming an extension area, and forging the extension piece on one side of the heat pipe bracket.

[0010] Furthermore: On one side of the punch portion of the upper template, corresponding to the position of the extension area, there is an extension protrusion. The thickness of the extension protrusion is less than that of the punch portion, so that it cooperates with the lower template to forge and form the extension piece of the heat pipe bracket.

[0011] Furthermore, corresponding clamping notches are provided at both ends of one side of the punch. When the punch is pressed into the die, the metal blank is squeezed and deformed at the clamping notches, thereby forging and forming the clamping boss of the heat pipe bracket.

[0012] Furthermore, a first groove is provided at the top of the protruding part of the punch, so that the punch is pressed into the die, thereby forging and forming the first boss of the heat pipe bracket.

[0013] Furthermore, at the bottom of the first groove, a second groove and a third groove are provided, so that the punch is pressed into the die, thereby forging and forming the second boss and the third boss of the heat pipe bracket.

[0014] Furthermore, a bottom groove is provided at the bottom of the die cavity, so that the punch is pressed into the die cavity, thereby forging and forming the bottom boss of the heat pipe bracket.

[0015] Furthermore, a first step is provided at the bottom of the die cavity, so that the punch is pressed into the die cavity, thereby forging and forming the first clearance area on the bottom surface of the heat pipe bracket.

[0016] Furthermore, a second step is provided at the bottom of the die cavity, so that the punch is pressed into the die cavity, thereby forging and forming the second clearance area on the bottom surface of the heat pipe support.

[0017] Furthermore, on one side of the bottom of the die portion, two sets of third steps are provided at both ends, so that the punch portion is pressed into the die portion, thereby forging and forming the third clearance area on the bottom surface of the heat pipe support.

[0018] Furthermore, at the bottom of the die cavity, there are multiple umbrella-shaped shallow pits, which allow the punch to be pressed into the die cavity, thereby forging and forming multiple umbrella-shaped protrusions on the bottom surface of the heat pipe support.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. Reduce mold costs and improve forging efficiency

[0021] By setting an extension area on the side of the die cavity, the extension protrusion of the upper template (thickness less than that of the punch) cooperates with the parting surface of the lower template to directly forge the extension sheet, avoiding the need to expand the area and depth of the die cavity in the traditional process, and significantly reducing the mold manufacturing and maintenance costs.

[0022] The extension zone is designed independently of the die, which optimizes the flow path of the metal billet during forging, reduces material redundancy, and improves forming efficiency.

[0023] 2. Precision molding of multi-part structures

[0024] Clamping bosses: The clamping notches at both ends of the punch compress the blank during forging to form two sets of clamping bosses, which realize stable clamping of the heat pipe and avoid positioning deviation caused by structural dispersion in traditional processes.

[0025] Multi-stage bosses: The first groove (top U-shaped structure) of the punch part, together with the second and third grooves at the bottom, are filled by the plastic deformation of the metal blank to precisely form the first, second and third bosses with different cross-sectional sizes, which facilitates the installation of external components such as cooling fans and fins and improves the product integration.

[0026] Bottom boss and clearance area: The bottom groove of the bottom of the die forms the bottom boss, which is used to abut the heat-generating component; the first step, the second step and two sets of third steps (including semi-circular structures) respectively form the first, second and third clearance areas, which accurately avoid electronic components of different heights and shapes, and improve product compatibility.

[0027] Umbrella-shaped protrusions: The umbrella-shaped shallow pits at the four corners of the bottom of the die form umbrella-shaped protrusions, which provide stable support and limit for the heat pipe bracket, avoiding the cumbersome process of processing the support structure separately in traditional processes.

[0028] Through the above improvements, this utility model, through innovative structural design, reduces costs and improves efficiency while achieving integrated and precise molding of complex structures in multiple parts of the heat pipe bracket, significantly improving product performance and production economy.

Detailed Implementation

[0039] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] Please see Figures 1 to 6 In this embodiment of the present invention, a forming mold for a heat pipe bracket includes an upper mold plate 10 and a lower mold plate 20 that are correspondingly fitted to each other. The upper mold plate 10 has a punch 12 at one end facing the lower mold plate 20, and the lower mold plate 20 has a die 21 at one end facing the upper mold plate 10. During forging, the punch 12 and the die 21 are connected to each other, so that the punch 12 is inserted into the die 21 to form the forming area of ​​the heat pipe bracket 30. On the side of the die 21, a specific limiting structure is used to maintain a preset height gap between the upper mold plate 10 and the lower mold plate 20, thereby forming an extension area, and forging the extension piece 31 on one side of the heat pipe bracket 30.

[0041] Specifically, in the forging process, a grooved die is typically used in the lower die, while a protruding punch is used in the upper die. External hydraulic equipment drives the upper die, causing the punch to embed into the die. The blank placed in the die is then forged to form a plastic product of the corresponding shape. However, for products with extended sides, placing the extended portion within the die for forging requires expanding the die's area and depth, resulting in high mold manufacturing costs.

[0042] This invention provides an extension area on the side of the die portion 21, between the upper template 10 and the lower template 20, thereby directly forging the extended portion of the product. This not only improves forging efficiency but also reduces the area and depth of the die portion 21, saving on mold manufacturing costs.

[0043] like Figure 1 and Figure 3 As shown, preferably, on one side of the punch portion 12 of the upper template 10, corresponding to the position of the extension area, there is an extension protrusion 11. The thickness of the extension protrusion 11 is less than that of the punch portion 12, so that it cooperates with the lower template 20 to forge and form the extension piece 31 of the heat pipe support 30.

[0044] Specifically, since the extension area corresponds to the outer side of the die portion 21 and is located on the parting surface of the lower template 20, a corresponding extension protrusion 11 needs to be provided on the outer side of the punch portion 12 at the position corresponding to the extension area. The thickness of the extension protrusion 11 should be less than that of the punch portion 12, so that a corresponding extension area is formed on the parting surface of the extension protrusion 11 and the lower template 20, and the extension piece 31 of the heat pipe bracket 30 is forged.

[0045] Secondly, the shape and area of ​​the extended protrusion 11 can be set according to the production needs of the extended sheet 31. Since the metal billet may have a certain allowance during the pre-manufacturing process, the size of the extended sheet 31 may be slightly larger than the preset size of the product after forging. This can be removed using the metal trimming process in the prior art. As for the other parts of the non-extended sheet of the heat pipe bracket 30, they are all forged in the groove of the die portion 21, which is equivalent to forming a closed die cavity. Therefore, there is no flash and no need to remove it.

[0046] like Figure 3 and Figure 5 As shown, preferably, the two ends of the punch 12 are respectively provided with corresponding clamping notches 13. When the punch 12 is pressed into the die 21, the metal blank is squeezed and deformed at the clamping notches 13, thereby forging and forming the clamping boss 32 of the heat pipe bracket 30.

[0047] Specifically, the heat pipe support 30 needs to be equipped with clamping bosses 32 to clamp and assist in fixing the heat pipe. Therefore, corresponding clamping notches 13 need to be provided in the punch portion 12. Since it is for auxiliary clamping of the heat pipe, two sets of clamping bosses 32 need to be provided at both ends, and the clamping notches 13 are also set as two sets distributed at both ends. Thus, the punch portion 12 between the two sets of clamping notches 13 can forge the heat pipe support 30 to form a groove portion to accommodate the heat pipe. The clamping notch portion 13 can be forged into the corresponding clamping boss 32 portion, thereby clamping and fixing the heat pipe.

[0048] like Figure 3 and Figure 5 As shown, preferably, the top of the protruding part of the punch 12 is further provided with a first groove 14, so that the punch 12 is pressed into the die 21, thereby forging and forming the first boss 33 of the heat pipe bracket 30.

[0049] Specifically, on the top surface of the heat pipe bracket 30, in the middle part where the heat pipe is placed, a first boss 33 is also required to facilitate the isolation of different heat pipes and the installation of other external mounting components such as cooling fans and cooling fins. Therefore, a U-shaped first groove 14 can be provided on the top surface of the protrusion of the punch part 12 so that it can avoid the blank during the forging process and form the corresponding first boss 33.

[0050] like Figure 3 and Figure 5 As shown, preferably, a second groove 15 and a third groove 16 are also provided at the bottom of the first groove 14, so that the punch 12 is pressed into the die 21, thereby forging and forming the second boss 34 and the third boss 35 of the heat pipe bracket 30.

[0051] Specifically, when the punch 12 is pressed into the die 21, the metal blank undergoes plastic deformation under the surrounding pressure because it cannot extend due to space constraints. It fills and bulges into the second groove 15 and the third groove 16, thereby forging and forming the second boss 34 and the third boss 35 of the heat pipe bracket 30.

[0052] Secondly, to facilitate the installation of other external components, preferably, a second boss 34 and a third boss 35 can be provided on the first boss 33. The cross-sectional dimension of the second boss 34 is smaller than that of the first boss 33 but larger than that of the third boss 35, and is used to mate with larger mounting components. The cross-sectional dimension of the third boss 35 is relatively smaller, and two can be provided to install smaller mounting components. Therefore, a second groove 15 of corresponding area and two smaller third grooves 16 can be provided at the bottom of the first groove 14 of the punch portion 12, so that they can avoid the blank during the forging process and form the corresponding second boss 34 and third boss 35.

[0053] like Figure 4 and Figure 6 As shown, preferably, a bottom groove 22 is provided at the bottom of the die portion 21, so that the punch portion 12 is pressed into the die portion 21, thereby forging and forming the bottom boss 40 of the heat pipe bracket 30.

[0054] Specifically, a boss needs to be provided on the bottom surface of the heat pipe bracket 30 to abut against the corresponding heating component. Therefore, a corresponding bottom groove 22 can be provided at the bottom of the die part 21 so that it can accommodate the blank during the forging process and form the corresponding bottom boss 40.

[0055] Secondly, a discharge through hole 23 can be provided at the bottom of the bottom groove 22, so that the discharge ejector of the molding die (not shown in the figure) can pass through the discharge through hole 23 during the mold opening and discharge process to eject the molded part, so that the part is ejected from the groove of the bottom groove 22 and the groove of the die part 21, thereby smoothly carrying out the discharge operation.

[0056] like Figure 4 and Figure 6 As shown, preferably, a first step 24 is provided at the bottom of the die portion 21, so that the punch portion 12 is pressed into the die portion 21, thereby forging and forming the first clearance area 41 on the bottom surface of the heat pipe bracket 30.

[0057] Specifically, a first clearance area 41 needs to be set on the bottom surface of the heat pipe bracket 30 to avoid the corresponding electronic components. Therefore, a corresponding first step 24 can be set at the bottom of the die part 21 so that the blank is squeezed during the forging process to form the corresponding first clearance area 41.

[0058] like Figure 4 and Figure 6 As shown, preferably, a second step 25 is provided at the bottom of the die portion 21, so that the punch portion 12 is pressed into the die portion 21, thereby forging and forming the second clearance area 42 on the bottom surface of the heat pipe support 30.

[0059] Specifically, a second clearance area 42 needs to be set on the bottom surface of the heat pipe bracket 30 to avoid the corresponding electronic components. Therefore, a corresponding second step 25 can be set at the bottom of the die part 21 so that the blank is squeezed during the forging process to form the corresponding second clearance area 42.

[0060] Secondly, the height of the second step 25 is greater than that of the first step 24, thus forming a higher second clearance area 42 to avoid components with higher heights at the corresponding positions.

[0061] like Figure 4 and Figure 6As shown, preferably, two sets of third steps 26 are provided at both ends on one side of the bottom of the die portion 21, so that the punch portion 12 is pressed into the die portion 21, thereby forging and forming the third clearance area 43 on the bottom surface of the heat pipe bracket 30.

[0062] Specifically, on one side of the bottom surface of the heat pipe bracket 30, two sets of third clearance areas 43 need to be set at both ends to avoid the corresponding electronic components. Therefore, two sets of third steps 26 can be set at the bottom of the die part 21 so that the blank is squeezed during the forging process to form two sets of third clearance areas 43.

[0063] Secondly, due to the special shape of the external components, the third clearance area 43 needs to be set as a special semi-circle, so the cross section of the third step 26 is also set as a special semi-circle.

[0064] like Figure 4 and Figure 6 As shown, preferably, a plurality of umbrella-shaped shallow pits 27 are provided at the bottom of the concave die 21, so that the convex die 12 is pressed into the concave die 21, thereby forging and forming a plurality of umbrella-shaped protrusions 44 on the bottom surface of the heat pipe support 30.

[0065] Specifically, on the bottom surface of the heat pipe support 30, near the four corners, four sets of umbrella-shaped protrusions 44 need to be set to support and limit the heat pipe support 30. Therefore, four sets of umbrella-shaped shallow pits 27 can be set at the bottom of the die part 21, near the four corners, so that they can avoid the blank during the forging process and form the corresponding umbrella-shaped protrusions 44.

[0066] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
