Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of radiator mold equipment, in particular to a radiator forging mold, a radiator and an electronic device. BACKGROUND

[0002] To ensure the stable operation of the IGBT power module, the radiator as one of the core components plays a key role in ensuring that the components operate within the appropriate temperature range through effective heat dissipation mechanism, thereby prolonging the service life and reducing the power loss caused by high temperature, and thus improving the efficiency.

[0003] The radiator can be prepared by forging, which generally needs to go through processes such as forging, pin cutting and shaping. Chinese patent application CN117798258A discloses a pin-type radiator column cutting machine, which fixes the pin-column radiator with pin columns on the pin-type radiator column cutting machine, and cuts the pin columns neatly by a cutting knife to realize the pin cutting process.

[0004] As can be seen, after the blank completes a specific processing step, it needs to be transferred to the next processing area for subsequent processes. Since the blank needs to be frequently transported and transferred between processing steps, it will lead to a long overall preparation process of the radiator. In this process, the time consumed by the blank transportation will be significantly increased, thereby adversely affecting the production efficiency of the radiator.

[0005] On the other hand, the blank is prone to falling and colliding during the transfer process between processes, which may cause damage to the blank, thereby affecting the product quality and yield of the radiator, and even may adversely affect the working stability of the radiator. For example, during the transfer process of the blank, a clamp is usually used for clamping, but the clamp may not be clamped firmly. If the clamp fails to clamp the blank firmly, the blank may fall off and fall to the ground during transportation. If the blank collides with a hard object, it may be damaged, thereby affecting the quality of the finished product and reducing the yield of the radiator, and increasing the manufacturing cost of the radiator.

[0006] In addition, if a clamp is used to fix the blank during the transfer between processes, frequent clamping operations may also cause damage to the blank. For example, the contact part of the clamp with the blank may leave clamping marks or cause clamping damage on the surface of the blank, thereby affecting the production quality of the radiator.

[0093] As described in the background section, the manufacturing process of radiators in related technologies is relatively long, and the blanks are easily damaged during processing, which affects the production efficiency and quality of radiators.

[0094] The problem arises because existing technologies manufacture radiators through forging. The entire radiator manufacturing process includes steps such as blank forging, cutting needles after forging, shaping the needle posts, and deburring. However, in current technology, the blank needs to be transferred after each operation, which makes the radiator manufacturing process lengthy and thus affects the production efficiency of radiators.

[0095] During the production process, billets are prone to falling or colliding when transferred between different processes, resulting in damage. This damage may affect the quality and yield of the radiator, and may even negatively impact its operational stability. Furthermore, billets typically require clamping tools during process transfers, and frequent clamping operations can also damage the billets.

[0096] To address the aforementioned technical problems, this application provides a radiator forging die, a radiator, and an electronic device. The radiator forging die includes a base plate die and a first pin die. The base plate die supports and holds the blank to be forged. The first pin die moves toward the base plate die and extrudes the blank. During extrusion, a portion of the blank is forced into the first pin hole to form a pin. Then, a cutting assembly connected to the first pin die cuts the extruded pins to ensure that all pins are flush with the side facing the first pin die. This allows for the integration of at least the forging and pin-cutting steps through the radiator forging die, achieving integrated design, shortening the radiator manufacturing process, reducing the number of times the blank is handled between process steps, lowering the probability of damage during handling, and improving radiator production efficiency and product yield.

[0097] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0098] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a radiator forging die, including a base plate die 100 and a first pin die 200. The base plate die 100 is used to support the blank 4, for example, the blank 4 to be forged is placed on the base plate die 100, and the base plate die 100 can also withstand the extrusion pressure from the first pin die 200 during the forging process to ensure the stability of the forging process.

[0099] refer to Figure 1 , Figure 2 and Figure 3 , Figure 2 This is a schematic diagram showing the blank 4 placed on the base mold 100. Figure 3 This is a schematic diagram showing the first needle post mold 200 moving towards the base plate mold 100 and forging the extruded blank 4 to form the needle post. The first needle post mold 200 and the base plate mold 100 are aligned along a first direction (e.g., ...). Figure 2 The first needle post mold 200 has multiple first needle post holes 210 that penetrate the first needle post mold 200 along the first direction. The needle post main mold 220 can move up and down along the first direction. The first needle post mold 200 is used to press the blank 4 on the base plate mold 100 under the action of external force and form needle posts on the blank 4 through the first needle post holes 210.

[0100] refer to Figure 1 and Figure 4 , Figure 4 This is a schematic diagram showing the needle post after being cut by the cutting assembly 300. The cutting assembly 300 is connected to the first needle post mold 200. The cutting assembly 300 is used to cut the needle post on the blank 4 so that the needle post is flush with the side facing the first needle post mold 200.

[0101] This application provides a radiator forging die, which includes a base plate die 100 and a first pin die 200. The base plate die 100 is used to support and hold the blank 4 to be forged. The first pin die 200 moves toward the base plate die 100 and extrudes the blank 4. During the extrusion process, part of the blank 4 is extruded into the first pin hole 210 to form a pin. Then, the extruded pin is cut by a cutting assembly 300 connected to the first pin die 200 to ensure that the side of all pins facing the first pin die 200 remains flush. Thus, the radiator forging die can integrate at least the forging and pin cutting steps, realizing the integrated design of the radiator forging die, shortening the radiator manufacturing process, reducing the number of times the blank 4 is handled between process steps, reducing the probability of damage to the blank 4 during handling, and improving the production efficiency and product yield of the radiator.

[0102] refer to Figure 5 , Figure 6 and Figure 7 In some embodiments, the first needle post mold 200 includes a needle post main mold 220 and a first drive mechanism.

[0103] The main die 220 of the needle column has multiple first needle column holes 210. The main die 220 of the needle column can move up and down along the first direction under the action of external force. When the main die 220 of the needle column moves toward the blank 4 on the base plate mold 100 and extrudes the blank 4, it forges and forms the needle column.

[0104] The first drive mechanism (not shown in the figure) is used to drive the main mold 220 of the needle column to reciprocate along the first direction.

[0105] In this way, by using the first driving mechanism to drive the main die 220 of the pin column to move along the first direction, the automated lifting and lowering movement of the main die 220 of the pin column can be realized, thereby achieving the automated forging process of the radiator forging die, improving the working efficiency of the forging process, and thus improving the production efficiency of the radiator. The shape and height of the first pin column hole in this application can be set according to actual needs.

[0106] In some embodiments, the first drive mechanism may be a telescopic device that stretches and contracts along a first direction, thereby moving the main die 220 of the needle column along the first direction. The telescopic device may be a telescopic cylinder or a telescopic hydraulic cylinder.

[0107] The first driving mechanism may include a driving body and a connecting rod. The connecting rod passes through the main needle mold 220, and the driving body is connected to the connecting rod. The driving body drives the main needle mold 220 to move along a first direction by driving the connecting rod. The main needle mold 220 has a mounting hole for inserting the connecting rod, which is inserted into the mounting hole and connected to the main needle mold 220.

[0108] refer to Figures 4 to 8 In some embodiments, the forging die further includes a second main needle die 400, which is connected to the main needle post die 220. The second main needle die 400 has a plurality of second needle post holes 410, which are configured to correspond one-to-one with the first needle post holes 210. The second main needle die 400 is used to fix each needle post when the main needle post die 220 is detached from the needle post.

[0109] The second main die 400 can move relative to the main die 220 in the first direction. The portion of the second main die 400 with the second needle post hole 410 can be located between the main die 220 and the base die 100. During the forging process to form the needle post, the second main die 400 and the main die 220 simultaneously press towards the blank 4 on the base die 100, causing a portion of the blank 4 to pass sequentially through the second needle post hole 410 and the first needle post hole 210. After the needle post is formed, the main die 220 detaches from the needle post, and the portion of the second main die 400 corresponding to the second needle post hole 410 remains stationary to prevent bending or deformation of the formed needle post, ensuring that the needle post on the blank 4 extends along the first direction, thus shaping the needle post, ensuring its quality, and improving the practicality of the radiator forging die.

[0110] refer to Figures 5 to 8 In some embodiments, the second needle master mold 400 includes a shaping structure 420 and a second driving mechanism 430.

[0111] A shaping structure 420 is disposed between the main pin mold 220 and the base plate mold 100, and a second pin hole 410 is provided on the shaping structure 420. A second driving mechanism 430 is connected to the shaping structure 420, and the second driving mechanism 430 is used to drive the shaping structure 420 to reciprocate along a first direction. The shape and height of the second pin hole in this application can be set according to actual needs.

[0112] The shaping structure 420 can be plate-shaped or block-shaped. When the needle column main mold 220 is pressed toward the blank 4, the surface of the shaping structure 420 facing the needle column main mold 220 is in contact with the needle column main mold 220. The shaping structure 420 can also be pressed toward the blank 4 so that part of the blank 4 can pass through the second needle column hole 410 and the first needle column hole 210 in sequence.

[0113] Thus, the second main die 400, including the forming structure 420 and the second drive mechanism 430, enables automated movement of the second main die 400, improving forming efficiency and radiator production efficiency. The inclusion of the forming structure 420 and the second drive mechanism 430 also simplifies the structure of the second main die 400, reducing its manufacturing cost and that of the radiator forging die.

[0114] refer to Figures 5 to 8 In some embodiments, the second needle master mold 400 further includes a first connecting rod 440, which passes through the needle post master mold 220 along a first direction and connects to the shaping structure 420. One end of the first connecting rod 440 facing away from the shaping structure 420 is connected to a second driving mechanism 430. The shaping structure 420 has a through hole 222, through which the first connecting rod 440 passes and is movable relative to the needle post master mold 220 along the first direction.

[0115] In this way, by using the first connecting rod 440 extending along the first direction to connect the shaping structure 420, when the first connecting rod 440 passes through the needle column main mold 220, the side wall of the opening on the needle column main mold 220 can radially limit the first connecting rod 440, and guide the first connecting rod 440 to move along the first direction, thereby preventing the shaping structure 420 from shifting or shaking during the movement along the first direction, and improving the stability of the shaping structure 420 during the movement along the first direction.

[0116] By using the first connecting rod 440 to pass through the main die 220 and connect to the forming structure 420, it is possible to avoid the presence of additional parts between the main die 220 and the base plate die 100, thereby avoiding the influence of additional parts on the forging and extrusion process.

[0117] refer to Figure 8 In some embodiments, there are multiple first connecting rods 440, which are disposed on the outer periphery of the first needle post hole 210. The multiple first connecting rods 440 can be evenly and spaced along the outer periphery of the first needle post hole 210.

[0118] The second main die 400 also includes a first connecting plate 450, which is located on the side of the main die 220 facing away from the shaping structure 420. The first connecting plate 450 is connected to the second driving mechanism 430, and the end of each first connecting rod 440 facing away from the shaping structure 420 is connected to the first connecting plate 450.

[0119] In this way, by using the first connecting plate 450 to connect the ends of all the first connecting rods 440 facing away from the shaping structure 420, and connecting the first connecting plate 450 to the second driving mechanism 430, it is possible to drive multiple first connecting rods 440 to move along the first direction simultaneously through the second driving mechanism 430, thereby further improving the working stability of the shaping structure 420 moving along the first direction.

[0120] refer to Figure 4 and Figure 5 In some embodiments, the cutting assembly 300 includes a cutter 310 and a third drive mechanism 320. Along a first direction, the cutter 310 can be positioned between the shaping structure 420 and the pin column master mold 220. The cutter 310 along a second direction (e.g.) Figure 4 The second direction (X direction) moves and is used to cut the needle post protruding from the surface of the shaping structure 420 toward the first needle post mold 200, and the second direction is perpendicular to the first direction (e.g., Figure 4 (in the Y direction). The third drive mechanism 320 is used to drive the cutter 310 to move in the second direction.

[0121] In practice, the shaping structure 420 and the main die 220 move toward the blank 4 to compress the blank 4 to form a needle column. After that, the shaping structure 420 remains stationary, and the main die 220 moves away from the shaping structure 420 and separates from the shaping structure 420. At least a portion of the needle column will protrude from the surface of the shaping structure 420 toward the main die 220. The portion of the needle column protruding from the surface of the shaping structure 420 can be removed by using a cutter 310 so that the needle column formed on the needle blank 4 remains flush.

[0122] refer to Figures 4 to 6 In some embodiments, the main die 220 of the needle column has a groove 221 on the side facing the shaping structure 420 through which the cutter 310 can pass, and the groove 221 extends along a second direction.

[0123] In this way, by opening a groove 221 extending in the second direction on the side of the main die 220 facing the forming structure 420, and moving the cutter 310 along the extension direction of the groove 221, the cutter 310 can be guided, thereby improving the stability of the cutter 310 during its movement in the second direction, improving the working stability of the cutting assembly 300, and thus improving the working stability of the radiator forging die.

[0124] refer toFigure 5 In some embodiments, the cutting assembly 300 further includes a guide mechanism 330 connected to the cutter 310, the guide mechanism 330 being used to guide the cutter 310 to move in a second direction.

[0125] In this way, the cutting assembly 300 is connected to the cutter 310 by further setting a guide mechanism 330. During the movement of the cutter 310 along the second direction, the guide mechanism 330 can guide the cutter 310 to move along the second direction, thereby further improving the stability of the guide mechanism 330 during the movement along the second direction, and thus improving the working stability of the cutting assembly 300 and the radiator forging die.

[0126] In one possible implementation, the guide mechanism 330 can be a combination structure of a guide block and a guide groove. The guide groove can be formed in the main mold 220 of the needle column and can extend along the second direction. The guide block can be connected to the cutter 310 and can move in the guide groove along the second direction. By setting the guide block and the guide groove, the cutter 310 can be guided to move along the second direction, thereby improving the stability of the cutter 310 moving along the second direction.

[0127] refer to Figure 5 In other embodiments, the cutting assembly 300 may further include a second connecting plate 340, one end of the cutter 310 being connected to the second connecting plate 340, and the driving end of the third driving mechanism 320 being connected to the second connecting plate 340.

[0128] The guiding mechanism 330 may include a guide rod 331 and a guide sleeve 332. The guide rod 331 extends along a second direction and one end is connected to the second connecting plate 340. The guide sleeve 332 is disposed on the second driving mechanism 430. For example, the guide sleeve 332 can be connected to a non-moving part on the second driving mechanism 430. The guide rod 331 passes through the guide sleeve 332. The third driving mechanism 320 drives the guide rod 331 and the cutter 310 to move along the second direction through the second connecting plate 340.

[0129] In this way, by including the guide rod 331 and the guide sleeve 332, the guide mechanism 330 can not only guide the cutter 310 to move in the second direction, but also simplify the structure of the guide mechanism 330, thereby reducing the manufacturing cost of the guide mechanism 330. Furthermore, it can simplify the structure of the radiator forging die and reduce the manufacturing cost of the radiator forging die while ensuring the working stability of the radiator forging die.

[0130] In some embodiments, there are multiple guide sleeves 332, which can be arranged at intervals along the second direction, and each guide sleeve 332 can be fixedly connected to the second drive mechanism 430.

[0131] refer to Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 In some embodiments, the base plate mold 100 may include a base plate main mold 110, a pusher block assembly 120, and a first base 130.

[0132] The base plate main mold 110 has a mounting groove 111 extending along a first direction, which is used to receive the blank 4. A pusher block assembly 120 is disposed within the mounting groove 111 to support the blank 4, and the pusher block assembly 120 is used to push the blank 4 out of the mounting groove 111 towards the pin post main mold 220. A first base 130 is used to support the base plate main mold 110 and the pusher block assembly 120.

[0133] In this way, by setting the base plate main mold 110 and the pusher block assembly 120 on the first base 130, the base plate mold 100 can support the base plate main mold 110 and the pusher block assembly 120 through the first base 130, thereby preventing the base plate main mold 110 and the pusher block from moving along the first direction due to the downward pressure during the pressing of the first needle column mold 200, and ensuring that there is sufficient extrusion pressure in the forging process.

[0134] Furthermore, by setting an installation groove 111 on the base plate main mold 110, the billet 4 can be placed in the installation groove 111. The side wall of the installation groove 111 axially limits the billet 4 set in the installation groove 111, thereby preventing the billet 4 from shaking and shifting during the forging process and improving the stability of the forging process.

[0135] refer to Figures 9 to 11 In some embodiments, the base plate main mold 110 may include a second base 112 and a fourth drive mechanism 113. The second base 112 is disposed on the side of the first base 130 facing the pin column main mold 220, and the second base 112 has a mounting groove 111.

[0136] In some embodiments, the orthographic projection of the shaping structure 420 along the first direction can fall within the mounting groove 111, thereby enabling the shaping structure 420 to move into the mounting groove 111. When the shaping structure 420 and the second base 112 move towards each other along the first direction, the burrs formed by the extrusion of the outer periphery of the blank 4 can be sheared. This allows for machining of the forged blank 4, improving the appearance quality of the radiator.

[0137] Furthermore, by using the shaping structure 420 and the second base 112 to move in opposite directions along the first direction to remove burrs, the function of the radiator forging die can be further enriched, the integration level of the radiator forging die can be improved, and the production efficiency of the radiator can be increased.

[0138] The fourth drive mechanism 113 is connected to the first base 130, and the fourth drive mechanism 113 is used to drive the second base 112 to reciprocate along the first direction.

[0139] In this way, by using the fourth drive mechanism 113 to connect with the first base 130, and using the fourth drive mechanism 113 to drive the second base 112 to reciprocate along the first direction, in order to cooperate with the forming structure 420 to remove the burrs from the blank 4, the automation level of the base plate main mold 110 can be improved, thereby improving the automation level of the radiator forging mold and improving the working efficiency of the radiator forging mold.

[0140] In some embodiments, the fourth drive mechanism 113 can be disposed on the side of the first base 130 facing away from the base plate main mold 110. This can avoid the fourth drive mechanism 113 occupying a large space and affecting the forging process when the fourth drive mechanism 113 and the base plate main mold 110 are disposed on the same surface of the first base 130 at the same time.

[0141] refer to Figures 9 to 11 In some embodiments, the base plate main mold 110 may further include a connecting frame 114 and a second connecting rod 115. The connecting frame 114 is disposed on the side of the first base 130 facing away from the second base 112, and the connecting frame 114 is connected to the fourth drive mechanism 113. One end of the second connecting rod 115 is connected to the connecting frame 114, and the other end passes through the first base 130 and connects to the second base 112. The fourth drive mechanism 113 drives the connecting frame 114 to move the second connecting rod 115 and the second base 112 along a first direction.

[0142] In some embodiments, the second connecting rod 115 can extend along the first direction and pass through the first through hole 131 on the first base 130. The second connecting rod 115 can move relative to the first base 130 along the first direction under the drive of the fourth driving mechanism 113. When the second connecting rod 115 passes through the first through hole 131, the inner peripheral wall of the first through hole 131 will radially limit the second connecting rod 115, thereby ensuring that the second connecting rod 115 moves along the first direction, so as to guide the second base 112 to move along the first direction through the second connecting rod 115, thereby improving the stability of the second base 112 moving along the first direction.

[0143] In some embodiments, there may be multiple second connecting rods 115, which can be arranged circumferentially along the second base 112. One end of each second connecting rod 115 passes through the first base 130 and connects to the second base 112, and the other end of each second connecting rod 115 is connected to the connecting frame 114.

[0144] In this way, by setting multiple second connecting rods 115, the guiding effect of the second connecting rods 115 on the second base 112 when it moves in the first direction can be improved, further enhancing the stability of the second base 112 during the movement in the first direction, and improving the working stability of the radiator forging die.

[0145] In some embodiments, the fourth drive mechanism 113 can be a telescopic cylinder or a telescopic hydraulic cylinder. For example, the fourth drive mechanism 113 is a telescopic cylinder. The telescopic cylinder can move in a telescopic direction. The fixed end of the telescopic cylinder is disposed on the first base 130. The telescopic end of the telescopic cylinder can be connected to the connecting frame 114. When the telescopic cylinder moves in a telescopic direction, it can drive the connecting frame 114 to move in the first direction, and then drive the second connecting rod 115 to move in the first direction.

[0146] refer to Figures 9 to 13 In some embodiments, the pusher block assembly 120 may include a pusher block 121 and a fifth drive mechanism 122. The pusher block 121 is located on the side of the first base 130 facing the pin column main mold 220. The pusher block 121 is located in the mounting groove 111 and is used to carry the billet 4. Before forging, the billet 4 can be placed on the pusher block 121 in the mounting groove 111.

[0147] The fifth drive mechanism 122 is connected to the push block 121, and the fifth drive mechanism 122 can drive the push block 121 to reciprocate along the first direction. After the forging, needle cutting and burr removal processes are completed, the push block 121 is used to push the billet 4 out of the mounting groove 111 under the drive of the fifth drive mechanism 122, so as to realize the step of taking the billet 4 out of the mounting groove 111.

[0148] In some embodiments, the fifth drive mechanism 122 can be connected to the push block 121 via the third connecting rod. The first base 130 has a second through hole 132. One end of the third connecting rod passes through the first base 130 and connects to the push block 121. The inner peripheral wall of the second through hole 132 can radially limit and fix the third connecting rod, thereby enabling the third connecting rod to move along the first direction and ensuring the stability of the push block 121 moving along the first direction.

[0149] In this way, by using the pusher block 121 to push the billet 4 out of the mounting groove 111, the process of manually removing the billet 4 can be avoided, thereby improving the efficiency of removing the billet 4 from the mounting groove 111 and avoiding adverse effects such as scratches and bumps on the billet 4 and the side wall of the mounting groove 111 when manually removing the billet 4.

[0150] In some embodiments, the fifth drive mechanism 122 can be a telescopic cylinder or a telescopic hydraulic cylinder. For example, the fifth drive mechanism 122 can be a telescopic cylinder, with the fixed end of the telescopic cylinder disposed on the first base 130, and the telescopic end of the telescopic cylinder connected to the push block 121 through the third connecting rod. The telescopic cylinder can extend and retract in the first direction and can drive the third connecting rod and the push block 121 to move in the first direction.

[0151] refer to Figure 14 This application embodiment also provides a radiator 1, which is prepared by the above-mentioned radiator 1 forging mold. The radiator 1 includes a plurality of pins 3 and a heat sink 2, with the pins 3 disposed on the surface of the heat sink 2.

[0152] This application provides a radiator 1, which can be prepared by using the radiator 1 forging die described above. Since the radiator 1 forging die can perform forging, cutting and shaping steps, the number of times the radiator 1 is handled during the preparation process can be reduced, the probability of the radiator 1 being damaged due to handling during the preparation process can be reduced, the product quality of the radiator 1 can be improved, and the production efficiency of the radiator 1 can be improved.

[0153] This application also provides an electronic device that includes the aforementioned heat sink. By using the aforementioned heat sink, the electronic device can improve production efficiency and product quality, and ensure its safety during use.

[0154] In some embodiments, the electronic device can be a vehicle, and the heat sink can be used to dissipate heat from the insulated gate bipolar transistor (IGBT) in the vehicle. Due to the relatively high product quality of the heat sink, the operational stability of the heat sink when dissipating heat from the IGBT can be ensured.
