Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling devices, specifically a mold cooling device. Background Technology
[0002] The outer shell of the electromechanical box is usually manufactured using injection molding. In this process, molten plastic is injected into a mold cavity, cooled, and solidified to form the desired part shape. The mold plays a shaping role in this stage, ensuring that the size, shape, and appearance quality of the part meet the design requirements.
[0003] During injection molding, the mold needs to be cooled to ensure that the plastic part can solidify quickly and reach the required strength. Cooling also prevents the part from deforming or shrinking after demolding.
[0004] Existing mold cooling methods typically employ circulating cooling water to cool the product within the mold. However, during use and observation, it has been found that the relatively stable flow of cooling water results in a limited contact area between the cooling water and the mold wall, thereby restricting the heat exchange efficiency for the product within the mold.
[0005] Therefore, a mold cooling device is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The mold cooling device of this utility model includes a mold, and a mold groove is provided in the middle of the mold; a pair of water pipes are connected to the middle of the mold; a turbine is provided on the inner wall of the water pipes; a rotating shaft is fixedly connected to the middle of the turbine; the rotating shaft and the inner wall of the mold are rotatably connected; a plurality of disturbance plates are fixedly connected to the middle of the rotating shaft; through the cooperation of the turbine and the disturbance plates, the turbine will drive the rotating shaft to rotate under the impact of water flow and cause the disturbance plates to agitate the cooling water in the mold, thereby increasing the contact area and contact frequency between the cooling water and the inner wall of the mold, and thus improving the cooling effect of the cooling water on the product in the mold groove.
[0008] Preferably, a plurality of rubber rods are fixedly connected to the bottom of the inner sidewall of the mold; the rubber rods and the disturbance plate are correspondingly arranged; as the disturbance plate rotates with the rotating shaft, when the disturbance plate rotates to the bottom of the rotating shaft, it will contact the rubber rods and strike them, and the rubber rods will transmit the vibration generated by the strike to the mold, so that the cooling water inside the mold will vibrate under the action of vibration, thereby improving the internal flow of the cooling water inside the mold.
[0009] Preferably, a connecting rod is fixed to the inner wall of the disturbance plate; a rotating wheel is rotatably connected to the middle of the connecting rod; when the disturbance plate rotates, it will move the connecting rod and the rotating wheel together. As the disturbance plate rotates, the rotating wheel will come into contact with the inner wall of the mold and rotate, so that the cooling water in the mold will be more agitated, further improving the activity of the cooling water in the mold.
[0010] Preferably, a pair of arc-shaped plates are rotatably connected to the middle of the connecting rod; the pair of arc-shaped plates are located on both sides of the rotating wheel and are fixedly connected to the rotating wheel; by setting the arc-shaped plates, the arc-shaped plates will reduce the turbulence and eddies on both sides of the rotating wheel, thereby allowing the fluid to flow more smoothly through the rotating wheel and reducing the fluid resistance encountered by the rotating wheel when it rotates.
[0011] Preferably, an air duct is provided through the middle of the mold; an air outlet is connected to the end of the air duct; the air outlet has a frustum structure; when it is necessary to cool the product inside the mold cavity, the end of the air duct can be connected to a cooler to allow the cool airflow to enter the interior of the air duct. The cooling airflow will enter the interior of the air outlet through the air duct. Because the air outlet has a frustum structure, the airflow will be sprayed out to the surrounding area through the air outlet, expanding the flow range of the airflow and increasing the cooling airflow reaching the moving mold. At the same time, when the cooling airflow flows in the air duct, it will perform secondary cooling on the cooling water accumulated in the mold, improving the cooling effect of the cooling water on the product inside the mold cavity.
[0012] Preferably, the inner wall of the air duct is fixed with multiple baffles; the baffles are arranged in an inclined and staggered manner; when the cooling airflow inside the air duct performs secondary cooling on the cooling water in the mold, the airflow will pass through the baffles. Because the baffles are arranged in an inclined and staggered manner, the flow path of the airflow in the air duct is increased, thereby increasing the cooling time of the airflow on the cooling water.
[0013] The advantages of this utility model are:
[0014] 1. The mold cooling device of this utility model, through the combined action of the turbine and the disturbance plate, causes the turbine to drive the rotating shaft to rotate under the impact of water flow and causes the disturbance plate to agitate the cooling water in the mold, thereby increasing the contact area and contact frequency between the cooling water and the inner wall of the mold, and thus improving the cooling effect of the cooling water on the product in the mold cavity.
[0015] 2. In the mold cooling device described in this utility model, when the disturbance plate rotates to the bottom of the rotating shaft, it will come into contact with the rubber rod and strike it. The rubber rod will transmit the vibration generated by the strike to the mold, causing the cooling water inside the mold to vibrate under the vibration, thereby increasing the activity of the cooling water inside the mold.

[0023] 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 scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] Please see Figures 1 to 5As shown in the embodiment of this utility model, a mold cooling device includes a mold 1 with a mold groove 13 in the middle. A pair of water pipes 12 are connected to the middle of the mold 1. A turbine 16 is provided on the inner wall of the water pipes 12. A rotating shaft 14 is fixedly connected to the middle of the turbine 16. The rotating shaft 14 and the inner wall of the mold 1 are rotatably connected. Multiple disturbance plates 15 are fixedly connected to the middle of the rotating shaft 14. During operation, the product inside is shaped by the cooperation of the moving mold and the mold groove 13. When it is necessary to cool and shape the product inside the mold groove 13, the valves of the pair of water pipes 12 can be opened and one of them can be connected to a water pump, so that cooling water can enter the interior of the mold 1 through the water pipes 12. When the cooling water passes through the water pipes 12, it will come into contact with the turbine 16. The turbine 16 will rotate under the impact of the water flow, and the turbine 16 will drive the rotating shaft 16. When the turbine 16 rotates together with the rotating shaft 14 and the disturbance plate 15, the turbine 16 will also rotate together with the rotating shaft 14 and the disturbance plate 15 will agitate the cooling water accumulated in the mold 1, so that the cooling water inside the mold 1 is in an oscillating state. A water pump is connected to another water pipe 12 so that the cooling water can be discharged from the water pipe 12. Similarly, the turbine 16 will also swing the cooling water through the rotating shaft 14 and the disturbance plate 15 to realize the circulation of cooling water in the mold 1. The cooling water can cool and lower the product inside the mold cavity 13 through the heat exchange of the mold 1. Through the cooperation of the turbine 16 and the disturbance plate 15, the turbine 16 will drive the rotating shaft 14 to rotate under the impact of the water flow and agitate the cooling water inside the mold 1 with the disturbance plate 15, increasing the contact area and contact frequency between the cooling water and the inner wall of the mold 1, thereby improving the cooling effect of the cooling water on the product inside the mold cavity 13.
[0026] Please see Figure 4 As shown, multiple rubber rods 2 are fixed to the bottom of the inner wall of the mold 1; the rubber rods 2 and the disturbance plate 15 are arranged correspondingly; when the disturbance plate 15 rotates with the rotating shaft 14, it will contact the rubber rods 2 and strike them when the disturbance plate 15 rotates to the bottom of the rotating shaft 14. The rubber rods 2 will transmit the vibration generated by the strike to the mold 1, so that the cooling water inside the mold 1 will vibrate under the action of vibration, thereby increasing the activity of the cooling water inside the mold 1.
[0027] Please see Figure 4 As shown, a connecting rod 3 is fixedly connected to the inner wall of the disturbance plate 15; a rotating wheel 32 is rotatably connected to the middle of the connecting rod 3; when the disturbance plate 15 rotates, it will move the connecting rod 3 and the rotating wheel 32 together. As the disturbance plate 15 rotates, the rotating wheel 32 will come into contact with the inner wall of the mold 1 and rotate, so that the cooling water in the mold 1 will be more agitated, further improving the activity of the cooling water in the mold 1.
[0028] Please see Figure 4As shown, a pair of arc-shaped plates 4 are rotatably connected to the middle of the connecting rod 3; the pair of arc-shaped plates 4 are located on both sides of the rotating wheel 32 and are fixedly connected to the rotating wheel 32; by setting the arc-shaped plates 4, the arc-shaped plates 4 will reduce the turbulence and eddies on both sides of the rotating wheel 32, thereby allowing the fluid to flow more smoothly through the rotating wheel 32 and reducing the fluid resistance effect on the rotating wheel 32 when it rotates.
[0029] Please see Figure 2 and Figure 5 As shown, an air duct 5 is provided through the middle of the mold 1; an air outlet 52 is connected to the end of the air duct 5; the air outlet 52 has a frustum structure; when it is necessary to cool the product inside the mold cavity 13, the end of the air duct 5 can be connected to a cooler so that the cool airflow enters the interior of the air duct 5. The cooling airflow will enter the interior of the air outlet 52 through the air duct 5. Because the air outlet 52 has a frustum structure, the airflow will be sprayed out to the surrounding area through the air outlet 52, expanding the flow range of the airflow and increasing the cooling airflow reaching the moving mold. At the same time, when the cooling airflow flows in the air duct 5, it will perform secondary cooling on the cooling water accumulated in the mold 1, improving the cooling effect of the cooling water on the product inside the mold cavity 13.
[0030] Please see Figure 5 As shown, multiple baffles 6 are fixed to the inner wall of the air duct 5; the baffles 6 are arranged in an inclined and staggered manner; when the cooling airflow inside the air duct 5 performs secondary cooling on the cooling water inside the mold 1, the airflow will pass through the baffles 6. Because the baffles 6 are arranged in an inclined and staggered manner, the flow path of the airflow in the air duct 5 is increased, thereby increasing the cooling time of the airflow on the cooling water.
[0031] Working principle: The moving mold and the mold cavity 13 work together to shape the internal product. When cooling and molding of the product inside the mold cavity 13 is required, a pair of water pipe valves 12 can be opened and one of them can be connected to a water pump, allowing cooling water to enter the mold 1 through the water pipe 12. When the cooling water passes through the water pipe 12, it will come into contact with the turbine 16. The turbine 16 will rotate under the impact of the water flow, which will drive the rotating shaft 14 to rotate together. The disturbance plate 15 will then rotate together and agitate the cooling water accumulated in the mold 1. The movement causes the cooling water inside mold 1 to oscillate. A water pump connected to another water pipe 12 allows cooling water to be discharged from pipe 12. Similarly, the turbine 16 oscillates the cooling water via the rotating shaft 14 and the disturbance plate 15, achieving circulation of the cooling water within mold 1. The cooling water cools the product inside the mold cavity 13 through heat exchange within mold 1. As the disturbance plate 15 rotates with the rotating shaft 14, when it reaches the bottom of the rotating shaft 14, it contacts and strikes the rubber rod 2. The rubber rod 2 then dissipates the impact... The vibration is transmitted to the mold 1, causing the cooling water inside the mold 1 to oscillate under the vibration. When the disturbance plate 15 rotates, it moves the connecting rod 3 and the rotating wheel 32 together. As the rotating wheel 32 rotates with the disturbance plate 15, it comes into contact with the inner wall of the mold 1 and rotates, causing the cooling water inside the mold 1 to be more agitated. By setting the arc-shaped plate 4, the arc-shaped plate 4 reduces the turbulence and eddies on both sides of the rotating wheel 32, thereby allowing the fluid to flow more smoothly through the rotating wheel 32. When it is necessary to cool the product inside the mold cavity 13, the end of the air duct 5 can be connected to a cooling fan. The air mechanism causes the cold air to enter the interior of the air duct 5. The cooling air will enter the interior of the air outlet 52 through the air duct 5. Because the air outlet 52 has a frustum structure, the air will be sprayed out to the surrounding area through the air outlet 52, expanding the flow range of the air and increasing the cooling air flow to the moving mold. At the same time, when the cooling air flows in the air duct 5, it will perform secondary cooling on the cooling water accumulated in the mold 1. When the cooling air inside the air duct 5 performs secondary cooling on the cooling water in the mold 1, the air will pass through the baffle 6. Because the baffle 6 is inclined and staggered, it increases the flow path of the air in the air duct 5.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
