Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold cooling technology, specifically to a die-casting mold cooling assembly. Background Technology
[0002] In the die casting process, the die casting mold plays a crucial role, directly determining the key characteristics of the die casting, such as its shape, dimensional accuracy, and surface quality. During the die casting process, the mold heats up rapidly due to the continuous injection of high-temperature molten metal. Excessively high mold temperatures can cause thermal fatigue cracks on the mold surface, shortening the mold's service life and increasing production costs.
[0003] Currently, water spraying is a common method for cooling die-casting molds. It removes heat by spraying cold water onto the mold surface to achieve rapid cooling. However, in practical applications, this method often cannot simultaneously reduce the temperature of the surrounding environment while spraying water. During water spraying, although the surface temperature of the mold decreases, the ambient temperature rises due to water vapor evaporation and heat dissipation. The high temperature environment hinders further heat dissipation from the mold, creating a localized thermal environment that is not conducive to cooling, thus reducing the overall cooling efficiency of the mold.
[0004] Therefore, in order to address the above issues, the applicant needs to design a die-casting mold cooling assembly to solve the problem. Utility Model Content
[0005] The purpose of this invention is to provide a cooling assembly for die-casting molds to solve the problems mentioned in the background section.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a die-casting mold cooling assembly, including a support platform on which a die-casting mold is placed, and further including: a cooling mechanism disposed below the support platform, the cooling mechanism being used to spray cold water onto the support platform, the cooling mechanism including a circulating pipe containing cold water inside, a connecting rod being fixedly disposed on the circulating pipe, and the end of the connecting rod away from the circulating pipe being fixedly connected to the support platform, an extension pipe being fixedly connected to the circulating pipe, and a nozzle being disposed on the extension pipe; a cooling component disposed outside the die-casting mold, the cooling component being used to reduce the ambient temperature around the die-casting mold, the cooling component including a water inlet pipe connected to the circulating pipe, the water outlet end of the water inlet pipe being connected to a curved pipe, and the water outlet end of the curved pipe being connected to a drain pipe.
[0007] Furthermore, a support rod is fixedly installed on the bottom surface of the support platform, and a cold water pan is fixedly installed at the end of the support rod away from the support platform, and the outlet end of the drainage pipe extends to the inside of the cold water pan.
[0008] Through the above structural design, the structure of fixing the cold water pan with support rods allows the drainage pipe to collect and recover the sprayed cooling water back into the cold water pan.
[0009] Furthermore, a booster pump is fixedly installed inside the cold water pan, and a suction pipe is provided at the inlet end of the booster pump. The outlet end of the booster pump is connected to a water supply pipe, and the water supply pipe is connected to a circulation pipe.
[0010] Through the above structural design, a booster pump is integrated into the cold water pan and connected to the suction pipe and the water supply pipe to form a closed-loop water circulation system.
[0011] Furthermore, the cold water pan is connected to a connecting pipe, and the connecting pipe is connected to an external cold water source.
[0012] Through the above structural design, the configuration of connecting pipes to external cold water sources can replenish the water volume in the cold water pan and adjust the water temperature in real time.
[0013] Furthermore, a reinforcing block is provided on the outside of the curved pipe, and a fixing plate is fixedly installed on the reinforcing block, and the fixing plate is fixedly connected to the support platform.
[0014] Through the above structural design, the rigid support structure formed by the reinforcing block and the fixing plate firmly fixes the curved pipe to the support platform.
[0015] Furthermore, a stabilizing base is fixedly installed on the bottom surface of the pressurizing pump, and the stabilizing base is fixedly connected to the cold water pan.
[0016] Through the above structural design, the stabilizing base rigidly connects the booster pump base to the cold water pan, reducing vibration transmission during pump operation and improving stability.
[0017] Furthermore, a temperature sensor is provided on the inner side of the cold water pan, and the temperature sensor is electrically connected to the pressure pump, with the detection end of the temperature sensor extending below the surface of the cold water.
[0018] Through the above structural design, the linkage control between the temperature sensor and the booster pump enables intelligent water temperature management.
[0019] Furthermore, a mold temperature sensor is embedded in the top of the support platform, and the mold temperature sensor is electrically connected to the pressure pump.
[0020] Through the above structural design, the mold temperature sensor directly monitors the temperature of the mold body and forms a closed-loop control with the pressure pump.
[0021] Compared with the prior art, the beneficial effects of this utility model are: the die-casting mold cooling assembly achieves efficient mold cooling and thermal control of the surrounding environment through the dual-path coordinated cooling of the nozzle and the curved pipe, thereby improving cooling efficiency and extending mold life. The specific details are as follows:
[0022] 1. When in use, this die-casting mold cooling component adopts a dual-path cooling design. The nozzle sprays cold water directly onto the surface of the die-casting mold to quickly absorb the heat of the mold. At the same time, the curved pipe surrounds the outside of the mold and uses the pipe wall to exchange heat with the high-temperature ambient air, actively absorbing the heat around the mold. The dual system works together to avoid the problem of the ambient temperature rising due to single spraying, and improves the overall heat dissipation efficiency, effectively suppressing the formation of local thermal environment, thereby reducing the risk of mold thermal fatigue.
[0023] 2. When the die-casting mold cooling assembly is in use, the cooling water flows back to the cold water pan through the drainage pipe. The water temperature and mold temperature are monitored in real time by the temperature sensor, and the power of the booster pump and the replenishment of the external cold water source are controlled in conjunction. When the water temperature or mold temperature is detected to be too high, the cooling water flow rate is automatically increased and low-temperature water is added. After the temperature returns to normal, the energy consumption is reduced. This not only realizes the recycling of water resources, but also accurately matches the cooling needs. While ensuring the safe temperature of the mold, it minimizes energy consumption and extends the service life of the equipment. Attached Figure Description

[0029] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] like Figures 1-4 As shown, this utility model discloses a cooling assembly for a die-casting mold, including a support platform 1 on which a die-casting mold 10 is placed. It also includes a cooling mechanism 2 located below the support platform 1, which sprays cold water onto the support platform 1. The cooling mechanism 2 includes a circulating pipe 20 containing cold water, a connecting rod 21 fixedly mounted on the circulating pipe 20, and one end of the connecting rod 21 away from the circulating pipe 20 fixedly connected to the support platform 1. An extension pipe 22 is fixedly connected to the circulating pipe 20, and a nozzle 23 is mounted on the extension pipe 22. A cooling component 27 is located outside the die-casting mold 10, used to reduce the ambient temperature around the die-casting mold 10. The cooling component 27 includes a water inlet pipe 270 connected to the circulating pipe 20, a curved pipe 271 connected to the outlet end of the water inlet pipe 270, and a drain pipe 272 connected to the outlet end of the curved pipe 271.
[0031] like Figures 1-3 As shown, a support rod 11 is fixedly installed on the bottom surface of the support platform 1, and a cold water pan 12 is fixedly installed at the end of the support rod 11 away from the support platform 1. The outlet end of the drain pipe 272 extends to the inside of the cold water pan 12. By fixing the cold water pan 12 with the support rod 11, the drain pipe 272 can collect the sprayed cooling water into the cold water pan 12, realizing the recycling of cooling water and reducing water waste. At the same time, the cold water pan 12 serves as a water storage container, providing a stable water circulation foundation for the system and preventing high-temperature wastewater from stagnating around the mold, thereby indirectly reducing the negative impact of ambient temperature on cooling efficiency.
[0032] A booster pump 25 is fixedly installed inside the cold water pan 12, and a suction pipe 26 is provided at the inlet end of the booster pump 25. The outlet end of the booster pump 25 is connected to a water supply pipe 24, and the water supply pipe 24 is connected to the circulation pipe 20. The booster pump 25 is integrated in the cold water pan 12 and connected to the suction pipe 26 and the water supply pipe 24 to form a closed-loop water circulation system. The booster pump 25 directly draws low-temperature water from the cold water pan 12 and continuously delivers it to the circulation pipe 20 through the water supply pipe 24 to ensure stable water pressure in the nozzle 23, improve the flow efficiency of the cooling medium, avoid uneven cooling caused by insufficient water pressure, and reduce reliance on external pipelines due to the compact layout.
[0033] A connecting pipe 13 is connected to the cold water pan 12, and the connecting pipe 13 is connected to an external cold water source. The configuration of the external cold water source connected to the connecting pipe 13 can replenish the water volume in the cold water pan 12 in real time and adjust the water temperature. When the circulating water temperature rises due to heat absorption, the external cold water can quickly dilute the water temperature and maintain the low temperature state of the cooling medium, fundamentally ensuring the continuous cooling capacity of the system and preventing the reduction of mold cooling efficiency due to the cumulative rise of water temperature.
[0034] like Figure 4As shown, a reinforcing block 274 is provided on the outside of the curved pipe 271, and a fixing plate 273 is fixedly installed on the reinforcing block 274. The fixing plate 273 is fixedly connected to the support platform 1. The rigid support structure formed by the reinforcing block 274 and the fixing plate 273 firmly fixes the curved pipe 271 on the support platform 1, effectively suppressing the displacement of the pipe caused by water flow impact or equipment vibration, ensuring that the nozzle 23 is always aligned with the preset position of the mold, improving the cooling accuracy, reducing pipe stress fatigue, and extending the service life of the components.
[0035] like Figure 3 As shown, a stabilizing base 250 is fixedly installed on the bottom surface of the booster pump 25, and the stabilizing base 250 is fixedly connected to the cold water pan 12. The stabilizing base 250 rigidly connects the base of the booster pump 25 to the cold water pan 12, reducing the vibration transmission during pump operation. This not only reduces noise but also prevents vibration from affecting the pipe sealing and nozzle 23 positioning accuracy, thus improving the system's operational stability.
[0036] A temperature sensor is installed inside the cold water pan 12 and is electrically connected to the booster pump 25. The detection end of the temperature sensor extends below the surface of the cold water. The linkage control between the temperature sensor and the booster pump 25 realizes intelligent water temperature management. When the sensor detects that the water temperature in the cold water pan 12 exceeds the threshold, the booster pump 25 is automatically triggered to introduce external cold water to ensure that the cooling medium is always within the effective temperature range. This prevents high-temperature water from weakening the cooling effect and avoids energy waste caused by over-cooling.
[0037] The top of the support platform 1 is embedded with a mold temperature sensor, which is electrically connected to the pressure pump 25. The mold temperature sensor directly monitors the temperature of the mold body and forms a closed-loop control with the pressure pump 25. When the mold temperature rises abnormally, the cooling water supply intensity is automatically increased, and the flow rate is reduced after the temperature returns to normal, so as to achieve cooling on demand. While ensuring the safe temperature of the mold, it reduces ineffective cooling energy consumption and prevents the generation of thermal fatigue cracks.
[0038] When using this die-casting mold cooling assembly, the pressurizing pump 25 draws low-temperature cooling water from the cold water pan 12 and pumps it into the circulation pipe 20 through the water supply pipe 24. The water flow is divided into two paths that act simultaneously. One path sprays the water from the nozzle 23 through the extension pipe 22 to the surface of the die-casting mold 10 for direct and rapid cooling. The other path enters the curved pipe 271 outside the mold through the water inlet pipe 270. It uses the pipe wall to exchange heat with the high-temperature ambient air to absorb ambient heat. The water that has absorbed heat flows back to the cold water pan 12 through the drain pipe 272. The returned hot water is cooled and compensated by the external cold water source through the connecting pipe 13. At the same time, the temperature sensor monitors the water temperature of the cold water pan 12 and the mold temperature in real time and adjusts the power of the pressurizing pump 25 and the amount of cold water replenished in conjunction with the temperature sensor, thereby improving the mold cooling efficiency and suppressing the local ambient temperature rise.
[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
