[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4 This utility model provides an aluminum alloy die-casting mold, including a die-casting mold body 1; a connecting pipe 11 is fixedly connected to the side wall of the die-casting mold body 1; the connecting pipe 11 penetrates the wall of the die-casting mold body 1 and is fixedly connected to it; a pair of heat-absorbing plates 12 are fixedly connected to the side wall of the connecting pipe 11; the heat-absorbing plates 12 are symmetrically arranged on both sides of the connecting pipe 11 and have the same structure; a plurality of heat dissipation fins 13 are fixedly connected to the side wall of the heat-absorbing plates 12; the heat dissipation fins 13 are evenly distributed on the side wall of the heat-absorbing plates 12 and have the same structure; a pair of drive motors 14 are fixedly connected to the side wall of the die-casting mold body 1; the drive motors 14 are symmetrically arranged on both sides of the die-casting mold body 1 and have the same structure; a fan blade 15 is fixedly connected to the output end of the drive motor 14; during use, during the aluminum alloy die-casting process, the die-casting mold body 1 will generate a large amount of heat due to the molten metal. At this time, the connecting pipe 11 fixedly connected to the side wall of the die-casting mold body 1 can remove part of the heat through the internally flowing cooling medium. Simultaneously, the heat-absorbing plates 12 symmetrically fixed to both sides of the connecting pipe 11 quickly absorb the residual heat on the surface of the die-casting mold body 1 and conduct the heat to multiple heat sinks 13 evenly distributed on the side wall. The heat sinks 13 increase the heat dissipation area and accelerate the dissipation of heat into the air. When it is necessary to further improve the heat dissipation efficiency, the drive motors 14 symmetrically arranged on both sides of the die-casting mold body 1 are started. The output end of the drive motor 14 drives the fan blades 15 to rotate, generating airflow that blows towards the heat sinks 13 and the heat-absorbing plates 12, forcibly accelerating the heat loss and realizing the rapid cooling of the die-casting mold body 1. In this process, the connecting pipe 11, the heat-absorbing plates 12, and the heat sinks 13 cooperate to form a dual heat dissipation structure of active cooling plus passive heat dissipation, which greatly improves the heat dissipation speed of the die-casting mold body 1 and avoids the decrease in precision of the mold due to overheating. The forced air cooling design of the drive motors 14 and the fan blades 15 can be flexibly started and stopped according to the mold temperature, shortening the die-casting cycle and improving the production speed.

[0025] Furthermore, such as Figures 1-4 As shown, a rotating rod 2 is rotatably connected to the side wall of the heat sink 13; the rotating rod 2 penetrates the wall of the heat sink 13 and is rotatably connected to it; multiple blades 21 are uniformly fixed to the side wall of the rotating rod 2; multiple support rods 22 are fixedly fixed to the side wall of the rotating rod 2; the support rods 22 are uniformly distributed on the side wall of the rotating rod 2 and have the same structure; multiple cleaning brushes 23 are uniformly fixed to the side wall of the support rods 22; during use, after long-term use, dust and metal debris easily accumulate in the gaps of the heat sink 13. When the airflow generated by the fan blades 15 blows towards the heat sink 13, the airflow drives the blades 21 to rotate, causing the blades to rotate. The rotating rod 2 rotates synchronously, and at the same time, the support rods 22 evenly distributed on the side wall of the rotating rod 2 drive the cleaning brush 23 at the end to rotate synchronously. During the rotation, the cleaning brush 23 brushes away impurities on the surface and in the gaps of the heat sink 13 to prevent impurities from blocking the heat dissipation channels. During this process, the rotating rod 2 and the cleaning brush 23 cooperate to achieve automatic cleaning of the heat sink 13 without the need for manual disassembly and cleaning, reducing maintenance workload, improving heat dissipation uniformity, ensuring stable heat dissipation, and the cleaning brush 23 can keep the heat sink 13 clean for a long time, reducing the decrease in heat dissipation efficiency caused by the accumulation of impurities, and ensuring the long-term stable operation of the mold.

[0026] Furthermore, such as Figures 1-4 As shown, a pair of elastic plates 3 are symmetrically fixed to the side wall of the rotating rod 2; a pair of elastic rods 31 are fixed to the side wall of the heat absorption plate 12; the elastic rods 31 are symmetrically arranged on both sides of the heat absorption plate 12 and have the same structure; a counterweight ball 32 is fixed to the end of the elastic rod 31; the counterweight ball 32 corresponds to the position of the elastic plate 3; in use, when the rotating rod 2 rotates, the elastic plate 3 will rotate synchronously. When it rotates to the position of the counterweight ball 32, the elastic plate 3 will hit the wall of the counterweight ball 32, and under the action of the impact force, the elastic rod 31 will generate After the elastic plate 3 passes the counterweight ball 32, the elastic plate 3 can swing and generate a certain vibration effect by utilizing its elasticity, causing the rotating rod 2 to resonate. The vibration shakes off the dust and impurities attached to the surface of the cleaning brush 23. In this process, the elastic plate 3 works in conjunction with the elastic rod 31 and the counterweight ball 32 to solve the problem of dust and impurities adhering to the surface of the cleaning brush 23 after long-term use, thereby cleaning the surface, improving the subsequent cleaning effect, and reducing the accumulation and adhesion of dust and impurities on the surface of the heat sink 13.

[0027] Furthermore, such as Figures 1-4As shown, a protective cover 4 is fixedly connected to the side wall of the drive motor 14; a pair of guide pipes 41 are fixedly connected to the side wall of the protective cover 4; the guide pipes 41 are symmetrically arranged on both sides of the protective cover 4 and have the same structure; in use, when the drive motor 14 is started, the protective cover 4 fixedly connected to the side wall of the drive motor 14 can block the contact between foreign objects and the fan blades 15, avoiding damage caused by collision between the fan blades 15 and impurities. At the same time, the guide pipes 41 symmetrically fixed to both sides of the protective cover 4 can directionally guide the airflow generated by the fan blades 15, so that the airflow flows precisely along the channel of the guide pipes 41 to both sides of the die-casting mold body 1, reducing the waste of heat dissipation efficiency caused by airflow dispersion. In this process, the protective cover 4 effectively protects the fan blades 15, reduces the failure rate, and extends the service life. The directional flow design of the guide pipes 41 improves the airflow utilization rate, increases the sufficient airflow on both sides of the die-casting mold body 1, and further improves the heat dissipation speed. The protective cover 4 can prevent operators from accidentally touching the rotating fan blades 15, improving operational safety.

[0028] Furthermore, such as Figures 1-4 As shown, a pair of guide plates 5 are symmetrically fixed to the end of the guide pipe 41. In use, the airflow guided by the guide pipe 41 will pass through the pair of guide plates 5 symmetrically fixed to the end of the guide pipe 41 before reaching the heat dissipation area. The guide plates 5 diffuse the concentrated airflow output by the guide pipe 41 into a uniform fan-shaped airflow through a specific tilt angle, so that the airflow can cover more of the surface of the die-casting mold body 1, reducing the problem of slow heat dissipation caused by insufficient airflow in the die-casting mold body 1. In this process, the airflow diffusion function of the guide plates 5 improves the heat dissipation uniformity of the heat sink 13, reduces the stress concentration caused by local overheating in the die-casting mold body 1, further expands the heat dissipation range, and improves the overall heat dissipation effect.

[0029] Furthermore, such as Figures 1-4 As shown, the heat sink 13 has through holes 6 on its sidewall. In use, the through holes 6 on the sidewall of the heat sink 13 can break the limitation of the solid structure of the heat sink 13. When the airflow generated by the fan blade 15 flows through the heat sink 13, some of the airflow can pass through the through holes 6. On the one hand, this accelerates the dissipation of heat inside the heat sink 13, and on the other hand, it reduces the vortex formed by the airflow on the back of the heat sink 13, reduces airflow resistance, and improves airflow efficiency. In this process, the design of the through holes 6 indirectly increases the heat dissipation area of ​​the heat sink 13, while accelerating the internal heat conduction and further improving the heat dissipation speed.

[0030] Working Principle: During the aluminum alloy die-casting process, the die-casting mold body 1 generates a large amount of heat due to the molten metal. At this time, the connecting pipe 11 fixed to the side wall of the die-casting mold body 1 can remove some of the heat through the internal cooling medium. Simultaneously, the heat-absorbing plates 12 symmetrically fixed to both sides of the connecting pipe 11 quickly absorb the residual heat on the surface of the die-casting mold body 1 and conduct the heat to multiple heat sinks 13 evenly distributed on the side wall. The heat sinks 13 increase the heat dissipation area, accelerating the dissipation of heat into the air. When further improvement in heat dissipation efficiency is needed, the drive motors 14 symmetrically arranged on both sides of the die-casting mold body 1 are activated. The output of the drive motors 14 drives the fan blades 15 to rotate, generating airflow that blows towards the heat sinks 13 and the heat-absorbing plates 12, strongly... To accelerate heat loss and achieve rapid cooling of the die-casting mold body 1, dust and metal debris easily accumulate in the gaps of the heat sink 13 after prolonged use. When the airflow generated by the fan blade 15 blows towards the heat sink 13, the airflow drives the blade 21 to rotate, causing the rotating rod 2 to rotate synchronously. At the same time, the evenly distributed support rods 22 on the side wall of the rotating rod 2 drive the cleaning brush 23 at the end to rotate synchronously. During the rotation, the cleaning brush 23 brushes away impurities on the surface and in the gaps of the heat sink 13, preventing impurities from clogging the heat dissipation channels. During use, as the rotating rod 2 rotates, the elastic plate 3 rotates synchronously. When it rotates to the position of the counterweight ball 32, the elastic plate 3 will hit the wall of the counterweight ball 32. Under the impact force, the elastic rod 31 will generate After the elastic plate 3 passes the counterweight ball 32, the elasticity of the elastic plate 3 can generate a swing and a certain vibration effect, causing the rotating rod 2 to resonate. The vibration shakes off the dust and impurities attached to the surface of the cleaning brush 23. When the drive motor 14 is started, the protective cover 4 fixed to the side wall of the drive motor 14 can prevent foreign objects from contacting the fan blade 15, avoiding damage caused by collision between the fan blade 15 and impurities. At the same time, the guide pipes 41 symmetrically fixed to both sides of the protective cover 4 can directionally guide the airflow generated by the fan blade 15, so that the airflow flows precisely along the channel of the guide pipe 41 to both sides of the die-casting mold body 1, reducing the waste of heat dissipation efficiency caused by airflow dispersion. When in use, the airflow guided by the guide pipe 41 reaches the diffuser. Before the hot zone, the airflow passes through a pair of guide plates 5 symmetrically fixed to the end of the guide pipe 41. The guide plates 5 diffuse the concentrated airflow output from the guide pipe 41 into a uniform fan-shaped airflow through a specific tilt angle, so that the airflow can cover more of the surface of the die-casting mold body 1, reducing the problem of slow heat dissipation caused by insufficient airflow in the die-casting mold body 1. In use, the through holes 6 opened on the side wall of the heat sink 13 can break the limitation of the solid structure of the heat sink 13. When the airflow generated by the fan blade 15 flows through the heat sink 13, some of the airflow can pass through the through holes 6 to pass through the heat sink 13. On the one hand, it accelerates the dissipation of heat inside the heat sink 13, and on the other hand, it reduces the vortex formed by the airflow on the back of the heat sink 13, reduces airflow resistance, and improves airflow efficiency.
