Description

Technical Field

[0001] This utility model relates to the technical field of water-cooling equipment for molds, specifically a water-cooling equipment for casting aluminum molds for high-pressure cast aluminum rotors of motors. Background Technology

[0002] In the field of motor manufacturing, high-pressure die-cast aluminum rotors are widely used in various types of motors due to their excellent performance. With the continuous development of the motor manufacturing industry, higher requirements are being placed on the production quality and efficiency of die-cast aluminum rotors. High-efficiency, high-quality die-casting molds have become crucial, and water-cooling equipment, as an important means of mold cooling, is of great significance for improving mold performance and product quality.

[0003] However, existing water-cooled equipment for casting molds of high-pressure cast aluminum rotors for motors, while achieving cooling through water, also suffers from poor energy efficiency because the water absorbs heat from the mold during the cooling process, causing the water temperature to rise. Furthermore, the water needs to be recycled during the cooling process, and scale will form over time. Since the water-cooled equipment cannot effectively filter the water, the pipes are prone to blockage. Therefore, we propose a water-cooled equipment for casting molds of high-pressure cast aluminum rotors for motors. Utility Model Content

[0013] (III) Beneficial Effects

[0014] This utility model provides a water-cooling device for the aluminum casting mold of a high-pressure die-cast aluminum rotor for an electric motor, which has the following beneficial effects:

[0015] (1) The aluminum mold of the high-pressure cast aluminum rotor of this motor is cooled by water. With the heat recovery box and heat exchange tube, when using the water cooling equipment, the staff adds water to the heat recovery box and water cooling box as needed. Then the water supply pipe and return pipe are connected to the aluminum mold. When the aluminum mold needs to be cooled by water, the water pump is started. The water pump draws water through the water supply pipe and the water enters the aluminum mold through the water supply pipe. The water can absorb the heat of the aluminum mold. After absorbing the heat, the water enters the heat exchange tube through the return pipe. Since the heat exchange tube has a spiral structure, the water with heat can be heated by the water in the heat recovery box for a sufficient time to absorb heat, thereby achieving the effect of heat exchange. When the water in the heat recovery box reaches a certain temperature, the drain pipe and water inlet pipe can be connected to heating equipment or other equipment for use. The aluminum mold of the high-pressure cast aluminum rotor of the motor can recover and utilize heat with the water cooling equipment, thus achieving the purpose of energy saving.

[0016] (2) The aluminum mold of the high pressure cast aluminum rotor of this motor is cooled by water. When the water enters the water cooling box after heat exchange, the water will flow onto the filter element of the filter frame. At this time, the filter element filters the water to remove the scale in the water and avoid blockage of the pipe. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a water-cooled device for the aluminum casting mold of a high-pressure cast aluminum rotor for an electric motor, including a water-cooled box 1, a water-drawing pipe 2 bolted to one side of the water-cooled box 1, a refrigeration box 6 bolted to the other side of the water-cooled box 1, a heat dissipation mesh 7 opened on the front of the refrigeration box 6, a compressor 601 and a condenser 602 respectively installed inside the refrigeration box 6, a filter frame 101 installed inside the water-cooled box 1, a filter element 102 installed on the inner side of the filter frame 101, a heat recovery box 8 bolted to the top of the water-cooled box 1, a drain pipe 9 and a water inlet pipe 10 threadedly connected to one side of the heat recovery box 8, a return pipe 12 passing through the other side of the heat recovery box 8, and a heat exchange pipe 13 welded to one end of the return pipe 12.

[0024] Furthermore, a water pump 3 is threadedly connected to one end of the water pump pipe 2, and a water delivery pipe 4 is threadedly connected to one end of the water pump 3. By starting the water pump 3, the water pump 3 draws water from the source through the water pump pipe 2, and the water enters the aluminum casting mold through the water delivery pipe 4. The water can absorb the heat of the aluminum casting mold, and the water that has absorbed the heat enters the heat exchange pipe 13 through the return pipe 12.

[0025] Furthermore, an expansion valve 604 is threadedly connected to one side of the condenser 602, and an evaporator 606 is threadedly connected to one end of the expansion valve 604. The high-temperature and high-pressure refrigerant gas discharged from the compressor 601 is cooled by the condenser 602, and then the high-pressure liquid refrigerant is throttled and depressurized by the expansion valve 604 and delivered to the evaporator 606.

[0026] Furthermore, a refrigerant pipe 603 is welded to one side of the compressor 601, and the refrigerant pipe 603 is fixedly connected to the condenser 602. A return pipe 605 is welded to the other side of the compressor 601, and the return pipe 605 is fixedly connected to the evaporator 606. When the compressor 601 is running, it compresses the refrigerant and delivers it to the condenser 602 through the refrigerant pipe 603. Subsequently, the refrigerant flows back to the compressor 601 through the return pipe 605.

[0027] Furthermore, the top of the heat recovery box 8 is integrally formed with a water inlet pipe 11. The heat recovery box 8 has a hollow structure, and water can be filled into the heat recovery box 8 through the water inlet pipe 11.

[0028] Furthermore, the bottom of the water-cooled box 1 is threaded with support legs 5. There are four support legs 5, which are located at the four corners of the bottom of the water-cooled box 1. The support legs 5 make the water-cooling equipment more balanced and less prone to shaking.

[0029] Working Principle: After installation, the installation, fixation, and safety precautions of this utility model are checked. When using the water-cooling equipment, the operator adds water to the heat recovery tank 8 and the water-cooling tank 1 as needed. Then, the water supply pipe 4 and the return pipe 12 are connected to the aluminum casting mold. When the aluminum casting mold needs water cooling, the water pump 3 is started. The water pump 3 draws water through the water supply pipe 2, and the water enters the aluminum casting mold through the water supply pipe 4. The water absorbs the heat from the aluminum casting mold. After absorbing heat, the water enters the heat exchange pipe 13 through the return pipe 12. Because the heat exchange pipe 13 has a spiral structure, the water with heat can be heated by the water inside the heat recovery tank 8 for a sufficient time to absorb heat, thus achieving the effect of heat exchange. When the water inside the heat recovery tank 8 reaches a certain temperature after heat exchange, it can be cooled. The drain pipe 9 and the inlet pipe 10 are connected to heating equipment or other equipment for use. After heat exchange, the water enters the water-cooled box 1 and flows into the filter element 102 of the filter frame 101. At this time, the filter element 102 filters the water to remove scale. Meanwhile, the compressor 601 starts running, compresses the refrigerant and delivers it to the condenser 602 through the refrigeration pipe 603, and cools the high-temperature and high-pressure refrigerant gas discharged by the compressor 601. Then, the high-pressure liquid refrigerant is throttled and depressurized through the expansion valve 604 and delivered to the evaporator 606. At this time, the evaporator 606 absorbs the heat of the water, which lowers the water temperature. Subsequently, the refrigerant flows back to the compressor 601 through the return cooling pipe 605. This completes the use process of this utility model. This utility model has a simple structure and is safe and convenient to use.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
