Technical Field

[0001] The present invention relates to a cooling die-casting device for a pallet mold, belonging to the technical field of extrusion molds. Background Art

[0002] Currently, as the installation position of batteries in an energy storage system, the battery cabinet is the core of a container energy storage system. The battery pallet serves as a bearing platform for energy storage batteries within the battery cabinet and plays a role equivalent to the skeleton of the battery cabinet. Among all types of energy storage power station containers, aluminum alloy containers have occupied a considerable market share due to their advantages of light weight, beauty, corrosion resistance, high elasticity, easy processing, low cost, and long service life.

[0003] In these aluminum alloy containers, cast aluminum battery pallets are usually used. The production method of this pallet is one-time integral molding without subsequent welding processes, thus ensuring its excellent comprehensive mechanical properties. Since lightweight aluminum alloy materials are used, the lightweight requirement of the pallet is also met.

[0004] After retrieving the prior art, it is found that a Chinese patent with the publication number CN212285354U discloses a cooling die for an extruder, in which a liquid spraying head is used to cool the cooling cavity. However, when the coolant is sprayed, it cannot completely and evenly cover all positions of the mold, easily causing uneven heating of the mold and resulting in cracks, thereby affecting the quality of the casting.

[0046] In order to make the content of the present invention easier to be clearly understood, the present invention will be further described in detail below according to specific embodiments in conjunction with the drawings.

[0047] As Figures 1-5 shown, a tray mold cooling die-casting device includes:

[0048] A housing 100, in which an air cooling channel suitable for the circulation of cooling air is provided;

[0049] An air cooling component 200, which is arranged on the housing 100 and is suitable for driving the air flow in the air cooling channel 400;

[0050] A water cooling circulation component, which is installed in the housing 100 and is suitable for driving the circulating water to flow in the pipeline;

[0051] A mold, which is arranged in the housing 100. Four compressed gas interfaces 421 and fourteen water cooling interfaces 411 are provided on the mold. The water cooling interfaces 411 are suitable for being connected to the water cooling circulation component through pipelines;

[0052] The mold is also provided with an air cooling channel 400 that penetrates the mold and is suitable for driving the air flow in the air cooling channel by the air cooling component 200 to dissipate heat from the mold;

[0053] The die-casting mechanism is installed inside the housing 100. The die-casting mechanism is adapted to carry the mold, and a water-cooling pipeline is provided on the die-casting mechanism. The water-cooling pipeline is connected to the water-cooling circulation component and is adapted to cool the outer surface of the mold.

[0054] In this embodiment, as Figure 2 and Figure 3 shown, during the working process, the air-cooling component 200 drives the air flow in the air-cooling channel, and air-cools the outer surface of the mold through the through air-cooling channel 400. At the same time, the water-cooling circulation component drives the circulating water flow in the water-cooling pipeline on the die-casting mechanism to water-cool the outer surface of the mold. Meanwhile, water-cooling interfaces 411 and compressed gas interfaces 421 are configured inside the mold. In this way, cooling of the inside and outside of the mold is achieved simultaneously, avoiding problems such as cracks caused by uneven cooling, greatly improving the cooling efficiency. Using pure water or other special media as the coolant to avoid pipeline blockage or corrosion caused by water quality problems. A serpentine cooling channel is provided inside the mold, and the cooling water can be closer to the mold, improving the cooling efficiency and uniformity. At the same time, compressed air can also be introduced into the water-cooling interface 411 to clean the cooling channel, preventing the remaining circulating water from seeping into the mold and causing pores or other defects.

[0055] Specifically, as Figures 3-5 shown, the mold can have the following structure:

[0056] The upper mold 410 has water-cooling interfaces 411 opened thereon. The water-cooling interfaces 411 include seven pairs of water-cooling inlets and water-cooling outlets;

[0057] The lower mold 420 is provided with compressed gas interfaces 421. The compressed gas interfaces 421 include two pairs of compressed gas inlets and compressed gas outlets. The compressed gas inlets are adapted to connect to an external compressed gas source, and the compressed gas outlets are adapted to discharge compressed gas;

[0058] In the assembled state, a die-casting cavity adapted for die-casting is provided between the upper mold 410 and the lower mold 410.

[0059] In this embodiment, as Figures 3-5 shown, in the assembled state of the mold, a die-casting cavity is formed between the upper mold 410 and the lower mold 420. When implementing the die-casting process, the casting material is injected into the die-casting cavity for forming. Through the pressure between the upper mold 410 and the lower mold 420, the casting material completely fills the inside of the die-casting cavity, realizing the forming of the product. During the die-casting process, the water-cooling interface 411 water-cools the upper mold 410 through a pipeline to ensure that its temperature is within the set range; while the compressed gas interface 421 injects compressed gas into the lower mold 420. The cooperation of the two enables the die-casting process to be precisely controlled to meet the forming quality requirements.

[0060] Specifically, asFigure 3 As shown, the number of water-cooling interfaces 411 is greater than the number of compressed gas interfaces 421.

[0061] In this embodiment, as Figure 3 shown, the number of water-cooling interfaces 411 is 14, and the number of compressed gas interfaces 421 is 4. In some embodiments, the numbers of the water-cooling interfaces 411 and the compressed gas interfaces 421 are not limited and can be set according to specific requirements.

[0062] Specifically, as Figures 1-3 shown, the water-cooling circulation assembly may have the following structure:

[0063] A water tank 300, which is suitable for storing circulating water;

[0064] A heat exchanger 310, which is installed on the outer shell 100 and is respectively connected to the water tank 300 and the water-cooling interfaces 411 of the mold and is suitable for transferring the heat in the circulating water.

[0065] A circulation pump 320, which is respectively connected to the water tank 300 and the water-cooling interfaces 411 of the mold through pipelines and drives the circulating water to circulate in the pipelines.

[0066] Specifically, as Figures 1-2 shown, the air-cooling assembly 200 is suitable for driving air to flow through the heat exchanger 310 to cool the circulating water in the heat exchanger 310.

[0067] In this embodiment, as Figures 1-2 shown, the circulation pump 320 can be a water pump. When the water-cooling circulation assembly is operating, the water pump starts to pump water into the water tank 300, and then the water output from the water tank 300 enters the heat exchanger 310. A plurality of layers of fins are arranged in the heat exchanger 310. When the water flow passes through the fins, sufficient heat exchange is carried out therewith. After the fins absorb the heat in the water, the water temperature drops, and so on in a cycle, continuously taking away the heat in the mold. At the same time, under the action of the air-cooling assembly, the external air passes through the heat exchanger 310, accelerating the heat dissipation on the surface of the heat exchanger 310 and taking away the heat on the surface of the fins, realizing the rapid cooling of the heat exchanger 310, which helps to further improve the heat exchange efficiency. In addition, after the circulating water works continuously for a period of time, the temperature will gradually rise, reducing the cooling effect. At this time, the standby water tank 300 can be switched to use pre-cooled water for circulating cooling, and the hot water in the previous water tank 300 can be discharged through the discharge device to ensure continuous and efficient cooling during the water-cooling circulation process. The circulation pump 320 can also use a high-pressure pump or a piston pump to provide high-pressure cooling water to improve the cooling effect and speed.

[0068] Specifically, as Figure 2 shown, the heat exchanger 310 is a fin heat exchanger, and the fin heat exchanger includes a plurality of layers of fins arranged side by side.

[0069] In this embodiment, as Figures 1-2 shown, the air-cooling assembly 200 includes parts such as a motor and an impeller. Among them, the motor is placed on the outer shell 100, and the impeller is driven by the motor to rotate at a high speed. The rotating impeller accelerates the air, introduces the external air into the heat exchanger 310, so that the cooling air directly blows on the surface of the heat exchanger 310. During the air flow process, the heat on the surface of the heat exchanger 310 is continuously taken away, playing a role in accelerating cooling and enhancing the heat exchange efficiency; multiple layers of parallel thin plate-shaped fins are arranged inside the heat exchanger 310, and flow channels are formed between the fins. The fins are made of materials with high thermal conductivity, such as copper, to improve the heat exchange efficiency. The flow mode of the heat exchange medium in the flow channel can adopt cross convection or parallel flow mode. By adopting a multi-layer fin structure, the heat exchange area can be significantly increased, and the heat transfer between the medium and the solid can be accelerated. The fins are arranged in parallel, which can form a swirling flow of the fluid in the flow channel, enhance the fluid disturbance, and improve the convective heat transfer between the fluid and the hot surface. In summary, the structure of the fins increases the heat exchange area, and the swirling flow formed in the flow channel of the fins improves the convective heat transfer coefficient, thereby improving the overall heat exchange efficiency of the heat exchanger 310 and enhancing the cooling performance.

[0070] Specifically, as Figure 2 shown, the water-cooling circulation assembly further includes:

[0071] A circulation filter row, which is installed at the water inlet of the water tank 300;

[0072] The circulation filter row is suitable for filtering impurities entering the water tank 300.

[0073] In this embodiment, as Figure 2 shown, the circulation filter row is installed at the water inlet of the water tank 300 and includes structures such as a filter core and a filter net, which are used to filter the water flow entering the water tank 300. During the water-cooling circulation process, the water flows through the mold and absorbs a large amount of heat and then returns to the water tank 300. During the return process, tiny impurity particles are easily generated. The circulation filter row first uses the filter net to intercept larger impurities to avoid polluting the circulating water, and then uses the filter core. The filtering accuracy can select an appropriate mesh size according to the process requirements. The circulation filter row can effectively remove impurities in the water flow, ensure the cleanliness of the circulating water, avoid blockage of the mold or the heat exchanger 310, and extend the service life of the equipment.

[0074] Specifically, as Figure 1 shown, the die-casting mechanism can be the following structure:

[0075] A driving assembly, on which a push rod is provided;

[0076] A lower pressing seat 510, which is fixedly arranged on the outer shell 100;

[0077] The upper pressure plate 520 is movably arranged above the lower pressure seat 510, and the upper pressure plate 520 is fixedly connected to the push rod of the driving component;

[0078] The driving component is adapted to drive the push rod and drive the upper pressure plate 520 to apply pressure to the mold.

[0079] In this embodiment, as Figure 1 shown, at the beginning of the die-casting process, the hydraulic cylinder pushes the push rod connected to the end to move downward. The push rod drives the upper pressure plate 520 to move towards the lower pressure seat 510 until the lower pressure seat 510 and the upper pressure plate 520 clamp the mold to form a closed die-casting cavity. After the die-casting cavity is formed, the pre-melted metal material is injected for filling. The hydraulic cylinder can provide continuous pressure to ensure the tight closure during the die-casting process. After the metal material is completely solidified, the hydraulic cylinder retracts, the upper pressure plate 520 releases the extrusion on the mold, and the mold is opened to take out the formed product.

[0080] Specifically, as Figure 1 shown, the die-casting mechanism further includes:

[0081] A liquid cooling joint, which is arranged on the upper pressure plate 520;

[0082] The liquid cooling pipeline is arranged on the upper pressure plate and is connected to the water cooling circulation component through the liquid cooling joint.

[0083] In this embodiment, as Figure 1 and Figure 3 shown, to enhance the cooling effect on the upper mold 410, by cooperating with the cooling channels in the upper mold 410, the inside and outside of the mold are cooled simultaneously. The circulation pump 320 in the water cooling circulation component is used to provide pressure to transport the relatively low-temperature circulating water into the liquid cooling pipeline inside the upper pressure plate 520. When the circulating water flows through the pipeline, it absorbs the heat on the surface of the upper mold 410 and then returns to the water tank 300 for further cooling. The cold quantity of the water cooling circulation component can be used to cool the upper pressure plate 520 to prevent the upper mold 410 from deforming due to uneven temperature during the die-casting process and ensure the stability and service life of the upper mold 410.

[0084] Specifically, the driving component is a hydraulic cylinder.

[0085] In the specific embodiments described above, the technical problems solved, the technical solutions and the beneficial effects of the present invention are further described in detail. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
