Description

Technical Field

[0001] This utility model relates to the field of mold cooling technology, specifically a rapid cooling structure for die casting. Background Technology

[0002] Die casting molds are tools used to cast metal parts, and are used to complete the die casting process on a special die casting and forging machine. Traditional die casting molds mostly have poor heat dissipation and cannot achieve rapid cooling. When die casting metal, the inability to cool down quickly results in a particularly long die casting time for the metal parts.

[0003] Utility model CN219746293U discloses a novel rapid cooling structure for metal die-casting molds. The structure includes a support platform with several support columns fixedly installed at its bottom. A water tank is fixedly installed at the top of the platform, and a mounting sleeve is fixedly installed inside the water tank to hold the die-casting mold. A cooling mechanism is installed outside the mounting sleeve to cool the die-casting mold. A water supply mechanism is installed at the bottom of the platform to inject water into the water tank. This utility model allows for rapid heat dissipation from the die-casting mold, achieving a rapid cooling effect.

[0004] However, the above-mentioned existing technology still has shortcomings in use: the water supply mechanism in the above-mentioned existing technology does not have an effective and reliable heat dissipation and cooling function. That is to say, the water supplied to the water tank is in a high temperature state, which leads to low efficiency of heat exchange in the water tank, and thus greatly reduces the cooling effect.

[0005] Therefore, this utility model provides a rapid cooling structure for die casting. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rapid cooling structure for die casting to solve the problems mentioned in the background technology. This utility model has the functions of water tank air cooling and water pipe air cooling, which greatly reduces the temperature of the water pumped into the water tank, thereby improving the efficiency of heat exchange in the water tank and thus greatly improving the cooling effect on the mold.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rapid cooling structure for die casting, comprising a cooling section, on which a water tank, a water reservoir, and a water pump are provided. A support plate is fixedly connected to one side of the water tank, and a water reservoir is positioned above the support plate. A conical channel is provided through the middle of the water reservoir. A conical spiral tube located on one side of the water reservoir is fixedly connected to the water outlet pipe on the water reservoir. The large ends of both the conical spiral tube and the conical channel face the support plate. The water outlet of the conical spiral tube is connected to the water pump via a pipeline. The water inlet pipe on the water reservoir is connected to the water tank via a pipeline. A first blade and a second blade are provided on the support plate, opposite to the large ends of the conical spiral tube and the conical channel.

[0008] Furthermore, the water tank has a cylindrical structure, and the outlet pipe and the inlet pipe are tangentially connected to the outer peripheral wall of the water tank and are located on both sides of the water tank axis. The outlet pipe and the inlet pipe are parallel and have the same opening direction.

[0009] Furthermore, the number of water outlet pipes and water inlet pipes is at least two, and they are arranged along the axial direction of the water tank.

[0010] Furthermore, a conical spiral heat sink is fixedly connected to the inner peripheral wall of the conical channel.

[0011] Furthermore, the top of the pallet is provided with a first rotating shaft and a second rotating shaft that are fixedly connected to the first fan blade and the second fan blade, respectively. The first rotating shaft is connected to the second rotating shaft via a belt drive assembly. The bottom of the pallet is fixedly connected with a control motor, and the output shaft of the control motor is fixedly connected to one end of the first rotating shaft.

[0012] Furthermore, the top of the tray is fixedly connected by a vertical pole to a wind-gathering cover one and a wind-gathering cover two, which are respectively fitted outside the first fan blade and the second fan blade.

[0013] Furthermore, both the top of the water tank and the conical spiral pipe are fixedly connected to a wind baffle by a support rod.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model provides a conical channel running through the middle of a water tank, followed by a conical spiral pipe for drainage and connected to the water tank. Finally, a first fan blade and a second fan blade are installed below the conical channel and the conical spiral pipe. This allows the water entering the water tank and carrying high heat to cool down rapidly, significantly reducing the temperature of the water entering the water tank and thus greatly improving the efficiency of heat dissipation for the die-casting mold.

[0016] 2. By setting up a support plate, a first rotating shaft, a second rotating shaft, a belt drive group, and a control motor, the structure for rotating and driving the first and second fan blades has more reliable and stable heat dissipation control, a simpler structure, and lower manufacturing cost.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a rapid cooling structure for die casting, including a cooling part 1, on which a water tank 11, a water tank 12 and a water pump 13 are provided. The structure inside the water tank 11 is the same as the structure in the patent documents mentioned in the background art.

[0023] A support plate 2 is fixedly connected to one side of the water tank 11. In this embodiment, the support plate 2 is installed below the water tank 11, and a water tank 12 is set above the support plate 2. In specific implementation, two uprights can be welded to the support plate 2, and the top of the uprights is fixedly connected to the bottom of the water tank 12. A conical channel 3 is provided through the middle of the water tank 12. A conical spiral pipe 4 located on one side of the water tank 12 is fixedly connected to the water outlet pipe 121 on the water tank 12. The large ends of the conical spiral pipe 4 and the conical channel 3 are both facing the support plate 2. The function of the conical channel 3 is to increase the heat dissipation area of ​​the water in the water tank 12. The contact area between the conical spiral pipe 4 and the outside air is increased, which will improve the heat dissipation efficiency when hot water flows in it. The outlet of the conical spiral pipe 4 is connected to the water pump 13 through a pipeline. The water inlet pipe 122 on the water tank 12 is connected to the water tank 11 through a pipeline. After the water pump 13 is started, a water circulation is formed between the water tank 11 and the water tank 12.

[0024] The support plate 2 is equipped with a first blade 5 and a second blade 6 opposite to the large end of the conical spiral tube 4 and the conical channel 3. When the first blade 5 and the second blade 6 rotate, they accelerate the heat dissipation of the conical spiral tube 4 and the conical channel 3. This arrangement greatly reduces the temperature of the water entering the water tank 11, which helps to improve the efficiency of heat exchange in the water tank, thus improving the cooling effect on the mold. Both the water tank 12 and the top of the conical spiral tube 4 are fixedly connected to a baffle plate 104 by a support rod. The function of the baffle plate 104 is to disperse hot air in all directions and prevent hot air from accumulating.

[0025] In this embodiment, the water tank 12 has a cylindrical structure. The water outlet pipe 121 and the water inlet pipe 122 are tangentially connected to the outer peripheral wall of the water tank 12 and are located on both sides of the axis of the water tank 12. The water outlet pipe 121 and the water inlet pipe 122 are parallel and have the same opening direction. The purpose of this arrangement is to make the water discharged from the water tank 11 and entering the water tank 12 form a swirling state. With the pumping action of the water outlet pipe 121, the water in the water tank 12 flows and rotates throughout, and the water in the water tank 12 is in a state of uniform heat dissipation.

[0026] Furthermore, the number of water outlet pipes 121 and water inlet pipes 122 is at least two and they are arranged along the axial direction of the water tank 12. This arrangement greatly increases the rotation speed of the water in the water tank 12, which has the advantage of further improving the heat dissipation efficiency of the water in the water tank 12.

[0027] In this embodiment, a conical spiral heat sink 31 is fixedly connected to the inner peripheral wall of the conical channel 3. When the airflow flows through the conical channel 3, it will pass through the conical spiral heat sink 31. The conical spiral heat sink 31 can further increase the contact area between the conical channel 3 and the airflow, thereby further improving the efficiency of heat exchange between the conical channel 3 and the air.

[0028] In this embodiment, the top of the support plate 2 is provided with a first rotating shaft 7 and a second rotating shaft 8, which are respectively fixedly connected to the first fan blade 5 and the second fan blade 6. The first rotating shaft 7 is connected to the second rotating shaft 8 through a belt drive group 9. The belt drive group 9 includes two pulleys and a drive belt. A pulley is fixedly sleeved on both the first rotating shaft 7 and the second rotating shaft 8. A control motor 101 is fixedly connected to the bottom of the support plate 2. The output shaft of the control motor 101 is fixedly connected to one end of the first rotating shaft 7. When the control motor 101 drives the first rotating shaft 7 to rotate, the first fan blade 5 rotates, and the second fan blade 6 also rotates.

[0029] The top of the support plate 2 is fixedly connected by a pole to a wind-gathering shroud 102 and a wind-gathering shroud 203 respectively fitted outside the first fan blade 5 and the second fan blade 6. The function of the wind-gathering shroud 102 and the wind-gathering shroud 203 is to prevent the airflow generated by the rotation of the first fan blade 5 and the second fan blade 6 from dispersing, so that more airflow is blown toward the conical channel 3 and the conical spiral tube 4.

[0030] Working principle: The die-casting mold is placed in the mounting sleeve inside the water tank 11. The cooling water in the water tank 11 exchanges heat with the die-casting mold, which allows the heat of the die-casting mold to dissipate quickly, thus achieving a rapid cooling effect. The water pump 13 is started, and the water in the water tank 12 enters the water tank 11. The hot water in the water tank 11 flows back to the water tank 12, so that new cooling water enters the water tank 11 to participate in heat exchange. During this process, the control motor 101 is started, and the first rotating shaft 7 and the second rotating shaft 8 will rotate. At this time, the first fan blade 5 and the second fan blade 6 will rotate and generate airflow. The airflow passes through the conical channel 3 and the conical spiral tube 4, which rapidly cools the water in the water tank 12 and the water before entering the water tank 11, ensuring that the water in the water tank 11 can efficiently exchange heat.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
