Description

Technical Field

[0001] This invention belongs to the field of casting equipment technology, and in particular relates to a low-pressure, high-flow electromagnetic drive module. Background Technology

[0002] In the field of die casting for new energy vehicles, low-pressure, high-flow electromagnetic drive modules are key components ensuring the stable operation of fluid delivery systems such as cooling and lubrication during the die casting process. The die casting process for new energy vehicles has extremely stringent requirements for fluid delivery, necessitating modules that precisely control the flow of high-flow-rate cooling media and lubricants under low-pressure conditions to ensure the temperature of the die-casting mold remains stable within a reasonable range, guaranteeing the molding quality and production efficiency of the die-cast parts. Simultaneously, the die-casting workshop environment is characterized by high temperatures and high dust levels, requiring modules with excellent heat dissipation performance to cope with the heat generated during continuous operation. Furthermore, they must be easy to install and maintain quickly to adapt to the high-efficiency operation of new energy vehicle production lines. Existing technologies typically consist of a valve body and a drive module. The drive module is mounted on the valve body and uses electromagnetic force to drive the valve core to control fluid flow and shut-off. To address the heat dissipation issue, some modules incorporate heat sinks on the drive module casing, relying on natural cooling.

[0003] The high ambient temperature in the die-casting workshop makes the natural heat dissipation method of traditional heat sinks extremely inefficient. The heat generated by the drive module during long-term operation is difficult to dissipate, resulting in excessively high internal temperature. This reduces the response speed and control accuracy of the electromagnetic drive, affects the delivery of cooling and lubricating fluids, and consequently leads to abnormal temperature of the die-casting mold, affecting the quality of the die-cast parts and even shortening the service life of the module. This is because natural heat dissipation cannot withstand the high-temperature environment, and the rate of heat accumulation far exceeds the rate of heat dissipation. Summary of the Invention

[0004] The purpose of this invention is to provide a novel low-pressure, high-flow electromagnetic drive module structure. By combining the drive module components and the rapid heat conduction mechanism, it solves the problem that the natural heat dissipation method using heat sinks in the prior art is extremely inefficient and affects the delivery of cooling and lubricating fluids.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a low-pressure, high-flow electromagnetic drive module structure, comprising a valve body, with a drive module assembly connected to the top of the valve body. A rapid heat conduction mechanism is provided on the top of the drive module assembly, the rapid heat conduction mechanism including a sealing cover, the sealing cover being positioned above the drive module assembly, a heat-conducting block being fixedly connected to the bottom of the sealing cover, a heat dissipation cavity being formed on the top of the sealing cover, a fan being fixedly connected to the inner cavity of the heat dissipation cavity, a dustproof grille being fixedly connected to the inner cavity of the heat dissipation cavity, mounting holes being formed on both sides of the sealing cover, a spring being fixedly connected to one side of the inner cavity of the mounting hole, and a locking block being fixedly connected to one side of the spring. The sealing cover, positioned above the drive module assembly, provides a certain degree of protection for the drive module assembly, reducing the direct impact of external impurities on the drive module assembly. The heat-conducting block is in close contact with the drive module assembly, enabling rapid conduction of the heat generated by the drive module assembly during operation to the sealing cover. The cover prevents heat buildup inside the drive module assembly, while the heat dissipation cavity provides space for heat dissipation. When the fan starts, it accelerates airflow inside and outside the heat dissipation cavity, quickly dissipating the heat absorbed by the sealing cover to the external environment, significantly improving heat dissipation efficiency and ensuring that the temperature of the drive module assembly remains stable during continuous operation. This prevents high temperatures from affecting the response speed of the electromagnetic drive. The dustproof grille effectively blocks impurities in the die-casting workshop from entering the heat dissipation cavity and the drive module assembly, ensuring normal operation of the fan and stable operation of the drive module assembly, and reducing the probability of failures caused by dust. The mounting holes provide installation space for the spring and the locking block. The spring has an elastic reset function. When the locking block is squeezed by external force, the spring contracts, and the locking block retracts into the mounting hole. When the external force is removed, the spring extends, pushing the locking block out. The locking block cooperates with the corresponding structure on the drive module assembly, enabling quick connection and separation of the sealing cover and the drive module assembly without the need for special tools, simplifying the installation and disassembly process.

[0006] The invention is further configured such that the drive module assembly includes a protective shell, the bottom of which is connected to the valve body, and the inner wall of the protective shell is fixedly connected to the drive module body. The top of the drive module body has a heat-conducting groove that works with the heat-conducting block. Both sides of the inner cavity of the protective shell have locking holes that work with the locking blocks. The bottom of the protective shell is connected to the valve body, providing a protective barrier for the drive module body. This effectively isolates external interference such as dust and high-temperature airflow in the die-casting workshop of new energy vehicles. The drive module body is the core of the electromagnetic drive. The heat-conducting groove on its top works with the heat-conducting block to increase the contact area for heat transfer, allowing the heat generated by the drive module body to be conducted to the sealing cover more quickly, thus improving heat dissipation efficiency. The locking holes correspond to the locking blocks of the sealing cover, achieving a stable locking connection under the action of springs. This ensures the reliability of the connection between the rapid heat conduction mechanism and the drive module assembly, and facilitates the quick assembly and disassembly of both, meeting the high-efficiency maintenance needs of the production line.

[0007] The invention is further configured such that limiting grooves are provided on both sides of the bottom of the sealing cover, and limiting blocks that cooperate with the limiting grooves are fixedly connected to both sides of the inner wall of the protective shell. The limiting grooves and the limiting blocks on the inner wall of the protective shell cooperate with each other to play a role in precise positioning when installing the sealing cover. This ensures that the heat-conducting block of the sealing cover is accurately embedded in the heat-conducting groove of the drive module body, while ensuring the alignment of the card block and the card hole, and avoiding the impact of installation misalignment on heat dissipation and connection stability.

[0008] The present invention is further configured such that a fluid inlet channel is connected to one side of the valve body, and a fluid outlet channel is connected to the other side of the valve body. The fluid inlet channel on one side of the valve body and the fluid outlet channel on the other side constitute a conveying path for low-pressure, high-flow-rate fluid.

[0009] The invention is further configured such that a sealing seat is connected to the bottom of the protective shell, a sealing flange is fixedly connected to the bottom of the sealing seat, and the bottom of the sealing flange is fixedly connected to the valve body. The sealing seat and the sealing flange cooperate to form a multi-seal structure between the protective shell and the valve body. The sealing seat enhances the tightness of the connection between the protective shell and the sealing flange, and the sealing flange further blocks the fluid leakage path through its fixed connection with the valve body.

[0010] The invention is further configured such that heat dissipation fins are fixedly connected to the surface of the protective shell. The heat dissipation fins are circumferentially distributed, which increases the contact area between the protective shell and the outside air. They can dissipate the heat generated by the main body of the drive module through natural convection. In the high-temperature environment of the die-casting workshop of new energy vehicles, the heat dissipation fins and the fan of the fast heat conduction mechanism form a synergistic heat dissipation effect, which accelerates the heat dissipation speed.

[0011] The present invention is further configured such that a screw is threadedly connected to the top of the sealing flange, and the sealing flange is fixedly connected to the valve body through the screw. This fixed connection not only achieves a firm fixation between the sealing flange and the valve body, ensuring stable sealing performance, but also facilitates quick disassembly during maintenance.

[0012] The present invention has the following beneficial effects.

[0013] 1. This invention utilizes the close cooperation between the heat-conducting block and the heat-conducting groove at the bottom of the sealing cover to quickly conduct the heat generated by the drive module to the sealing cover. The fan in the heat dissipation cavity accelerates airflow, greatly improving heat dissipation efficiency. Even in a high-temperature die-casting workshop, the module temperature can be effectively controlled. The protective shell provides protection for the internal components, and the heat dissipation fins distributed around its surface work in conjunction with the rapid heat conduction mechanism to further enhance the heat dissipation effect, ensuring that the module temperature remains stable during continuous operation and improving the quality of die-cast parts.

[0014] 2. This invention achieves quick assembly and disassembly by using the locking blocks on both sides of the sealing cover and the locking holes of the protective shell, combined with the elasticity of the spring. No special tools are required, simplifying the maintenance process and reducing the impact of module maintenance on the production rhythm. The cooperation between the limiting groove and the limiting block ensures installation accuracy and avoids affecting module performance due to installation deviation. The fluid inlet and outlet channels on the valve body are adapted to low-pressure, high-flow conditions, ensuring smooth delivery of cooling medium and lubricant, and meeting the requirements of the die-casting process.

[0021] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1

[0022] Please see Figure 1-5This invention relates to a low-pressure, high-flow electromagnetic drive module structure, comprising a valve body 1, a drive module assembly 2 connected to the top of the valve body 1, a rapid heat conduction mechanism 3 provided on the top of the drive module assembly 2, the rapid heat conduction mechanism 3 including a sealing cover 31, the sealing cover 31 being disposed above the drive module assembly 2, a heat conduction block 32 fixedly connected to the bottom of the sealing cover 31, a heat dissipation cavity 33 opened on the top of the sealing cover 31, a fan 34 fixedly connected to the inner cavity of the heat dissipation cavity 33, a dustproof grille 35 fixedly connected to the inner cavity of the heat dissipation cavity 33, mounting holes 36 opened on both sides of the sealing cover 31, a spring 37 fixedly connected to one side of the inner cavity of the mounting hole 36, and a locking block 38 fixedly connected to one side of the spring 37.

[0023] Specifically: The sealing cover 31 is positioned above the drive module assembly 2, providing some protection and reducing the direct impact of external impurities on the drive module assembly 2. The heat-conducting block 32 is in close contact with the drive module assembly 2, enabling rapid heat transfer from the drive module assembly 2 during operation to the sealing cover 31, preventing heat accumulation inside the drive module assembly 2. The heat dissipation cavity 33 provides space for heat dissipation. When the fan 34 starts, it accelerates airflow inside and outside the heat dissipation cavity 33, rapidly dissipating the heat absorbed by the sealing cover 31 to the external environment, significantly improving heat dissipation efficiency and ensuring that the temperature of the drive module assembly 2 remains stable during continuous operation, preventing high temperatures from affecting the response speed of the electromagnetic drive. The dustproof grille 35 effectively blocks impurities in the die-casting workshop from entering the heat dissipation cavity 33 and the drive module assembly 2, ensuring the normal operation of the fan 34 and the stable operation of the drive module assembly 2, and reducing the probability of failure caused by dust. The mounting hole 36 provides installation space for the spring 37 and the locking block 38. The spring 37 has an elastic reset function. When the locking block 38 is squeezed by external force, the spring 37 contracts and the locking block 38 retracts into the mounting hole 36. When the external force disappears, the spring 37 extends and pushes the locking block 38 out. The locking block 38 cooperates with the corresponding structure on the drive module assembly 2, which can quickly realize the connection and separation of the sealing cover 31 and the drive module assembly 2 without the need for special tools, simplifying the installation and disassembly process. Example 2

[0024] Please see Figure 1-5Based on Embodiment 1, the drive module assembly 2 includes a protective shell 21. The bottom of the protective shell 21 is connected to the valve body 1. The inner wall of the protective shell 21 is fixedly connected to the drive module body 22. The top of the drive module body 22 is provided with a heat-conducting groove 23 that cooperates with the heat-conducting block 32. Both sides of the inner cavity of the protective shell 21 are provided with a locking hole 24 that cooperates with the locking block 38. Both sides of the bottom of the sealing cover 31 are provided with a limiting groove 4. Both sides of the inner wall of the protective shell 21 are fixedly connected with a limiting block 5 that cooperates with the limiting groove 4. One side of the valve body 1 is connected to a fluid inlet channel 6, and the other side of the valve body 1 is connected to a fluid outlet channel 7. The bottom of the protective shell 21 is connected to a sealing seat 8. The bottom of the sealing seat 8 is fixedly connected to a sealing flange 9. The bottom of the sealing flange 9 is fixedly connected to the valve body 1. The surface of the protective shell 21 is fixedly connected with heat dissipation fins 10, which are circumferentially distributed. The top of the sealing flange 9 is threadedly connected to a screw, and the sealing flange 9 is fixedly connected to the valve body 1 through the screw.

[0025] Specifically: The bottom of the protective shell 21 is connected to the valve body 1, providing a protective barrier for the drive module body 22. This effectively isolates external interference such as dust and high-temperature airflow in the new energy vehicle die-casting workshop. The drive module body 22 is the core of the electromagnetic drive. Its top heat-conducting groove 23 cooperates with the heat-conducting block 32 to increase the contact area for heat transfer, allowing the heat generated by the drive module body 22 to be conducted to the sealing cover 31 more quickly, improving heat dissipation efficiency. The locking hole 24 corresponds to the locking block 38 of the sealing cover 31, achieving a stable locking under the action of the spring 37. This ensures the reliability of the connection between the rapid heat conduction mechanism 3 and the drive module assembly 2, and facilitates the quick disassembly and assembly of both, meeting the high-efficiency maintenance needs of the production line. The limiting groove 4 cooperates with the limiting block 5 on the inner wall of the protective shell 21, playing a precise positioning role when installing the sealing cover 31. This ensures that the heat-conducting block 32 of the sealing cover 31 is accurately embedded in the heat-conducting groove 23 of the drive module body 22, while ensuring that the locking block 38 and the locking hole 24 are properly aligned. Alignment is ensured to prevent installation misalignment from affecting heat dissipation and connection stability. The fluid inlet channel 6 on one side of the valve body 1 and the fluid outlet channel 7 on the other side constitute a low-pressure, high-flow-rate fluid delivery path. The sealing seat 8 and the sealing flange 9 cooperate to form a multi-seal structure between the protective shell 21 and the valve body 1. The sealing seat 8 enhances the tightness of the connection between the protective shell 21 and the sealing flange 9. The sealing flange 9 further blocks the fluid leakage path through its fixed connection with the valve body 1. The heat dissipation fins 10 increase the contact area between the protective shell 21 and the outside air, and can dissipate the heat generated by the drive module body 22 through natural convection. In the high-temperature environment of the new energy vehicle die-casting workshop, the heat dissipation fins 10 and the fan 34 of the fast heat conduction mechanism 3 form a synergistic heat dissipation effect, accelerating the heat dissipation speed. The sealing flange 9 is fixedly connected to the valve body 1 by screws, which not only achieves a firm fixation between the sealing flange 9 and the valve body 1 and ensures stable sealing performance, but also facilitates quick disassembly during maintenance.

[0026] The working principle of this invention is as follows: the sealing flange 9 is fixedly connected to the valve body 1 by a screw, the sealing seat 8 at the bottom of the protective shell 21 is connected to the sealing flange 9, and the main body 22 of the drive module is fixed to the inner wall of the protective shell 21. The protective shell 21 isolates it from external interference such as dust and high-temperature airflow in the new energy vehicle die-casting workshop.

[0027] When installing the rapid heat conduction mechanism 3, the limiting groove 4 at the bottom of the sealing cover 31 cooperates with the limiting block 5 on the inner wall of the protective shell 21 to achieve precise positioning, ensuring that the heat conduction block 32 at the bottom of the sealing cover 31 is accurately embedded into the heat conduction groove 23 at the top of the drive module body 22. At the same time, the locking blocks 38 in the mounting holes 36 on both sides of the sealing cover 31 pop out under the action of the spring 37 and engage with the locking holes 24 on both sides of the inner cavity of the protective shell 21, thus completing the stable connection between the rapid heat conduction mechanism 3 and the drive module assembly 2. The drive module body 22 serves as the electromagnetic drive core, generating electromagnetic force to control the movement of the internal components of the valve body 1, thereby realizing the opening and closing of the fluid and the regulation of the flow rate. The fluid inlet channel 6 on one side of the valve body 1 introduces low-pressure, high-flow-rate fluid, which is then output from the fluid outlet channel 7 on the other side after passing through the internal flow channel of the valve body 1, thus meeting the fluid requirements in the die-casting process of new energy vehicles. The heat generated by the main body 22 of the drive module during operation is transferred to the heat-conducting block 32 of the sealing cover 31 through the top heat-conducting groove 23, and then conducted to the sealing cover 31. The fan 34 starts to accelerate air circulation and dissipate the heat of the sealing cover 31 to the outside. At the same time, the heat dissipation fins 10 distributed circumferentially on the surface of the protective shell 21 assist in heat dissipation through natural convection, forming a synergistic heat dissipation effect with the fan 34, which quickly reduces the temperature of the main body 22 of the drive module, ensuring its temperature stability during continuous operation and avoiding high temperature from affecting the electromagnetic drive response speed. When maintenance or repair is required, press the latches 38 on both sides of the sealing cover 31. The spring 37 will retract and cause the latches 38 to retract into the mounting hole 36, thus separating the rapid heat conduction mechanism 3 from the drive module assembly 2.
