Description

Technical Field

[0001] The present invention relates to the technical field of molds, and particularly to a mold for an aluminum alloy new energy vehicle sill beam. Background Art

[0002] In the field of new energy vehicle manufacturing, the aluminum alloy sill beam is one of the key structural components. The aluminum alloy sill beam is usually made of aluminum alloy material, which has the advantages of light weight, high strength, strong corrosion resistance, etc. It can effectively reduce the overall weight of the vehicle, and at the same time meet the structural strength and safety requirements of the vehicle during driving. The main functions of the aluminum alloy sill beam include: First, as an important supporting component of the vehicle body structure, it bears the load on the side of the vehicle and enhances the rigidity and stability of the vehicle body. Second, it works together with other structural components of the vehicle to form a complete vehicle body frame to ensure the overall performance of the vehicle during driving. Third, it provides installation and protection space for important components such as the vehicle's battery pack to ensure the normal operation and safety of new energy vehicles. During the production process of the aluminum alloy sill beam, a casting process is usually adopted, that is, molten aluminum alloy is injected into the mold to form it in the mold. In order to ensure the forming quality and production efficiency of the product, a water tank needs to be set in the mold, and coolant is introduced into the water tank when the product is formed to accelerate the cooling and solidification process of the aluminum alloy;

[0003] However, in actual production, when the coolant circulates in the mold water tank, it often carries some tiny particulate impurities, including chemical reaction products generated during the use of the coolant itself and wear particles on the inner wall of the mold. These particulate impurities flow in the mold water tank with the coolant and will gradually adhere to the inner wall of the water tank. After long-term accumulation, the flow channel of the water tank in the mold will gradually shrink, thereby affecting the heat absorption efficiency of the coolant for the product in the mold, and then reducing the production efficiency and even affecting the forming quality of the product.

[0004] To solve the above problems, a mold for an aluminum alloy new energy vehicle sill beam is proposed in this application. Summary of the Invention

The aeration pipe is arranged in the filter cartridge along its length direction. One end of the aeration pipe is connected with the rotating pipe, and one end of the rotating pipe is rotatably connected with the inner wall of one end of the water tank. A plurality of circumferentially arranged stirring plates are installed on the rotating pipe. The rotating pipe is driven by the driving assembly to rotate and drives the stirring plate to rotate accordingly. The small beads are sequentially pushed into the circulation assembly by the stirring plate.

[0011] As a further optimized solution of the present invention, a plurality of aeration nozzles arranged at intervals are connected along the length direction of the aeration pipe. The rotating pipe is communicated with the air supply assembly.

[0012] As a further optimized solution of the present invention, the air supply assembly includes a rotary joint, an air supply pipe and an air supply pump. One end of the rotating pipe rotatably passes through one end of the water tank. The rotary joint is installed at one end of the water tank. One end of the rotating pipe is connected with the rotary air outlet end of the rotary joint. The air inlet end of the rotary joint is connected with the air supply pipe. The air supply pump is connected with the end of the air supply pipe far away from the rotary joint.

[0013] As a further optimized solution of the present invention, the circulation assembly includes a return pipe and a liquid supply member. Two ends of the return pipe are respectively connected with the liquid outlet end of the mold body and one side of the filter cartridge. The liquid supply member is respectively connected with the liquid inlet end of the mold body and the other side of the filter cartridge.

[0014] As a further optimized solution of the present invention, the liquid supply member includes a water supply pump. The water supply pump is installed on the side of the water tank. The liquid inlet end of the water supply pump is connected with a water inlet pipe. One end of the water inlet pipe is connected with the other side of the filter cartridge. The liquid outlet end of the water supply pump is connected with a water supply pipe. The end of the water supply pipe far away from the water supply pump is connected with the liquid inlet end of the mold body.

[0015] As a further optimized solution of the present invention, the suction assembly includes an extraction cylinder and an extraction member. The extraction cylinder is installed on the top of the water tank, and the bottom end of the extraction cylinder is communicated with the top of the filter cartridge. The extraction member is communicated with the extraction cylinder.

[0016] As a further optimized solution of the present invention, the extraction member includes an extraction pipe and an extraction pump. One end of the extraction cylinder is connected to the extraction pipe, and the end of the extraction pipe away from the extraction cylinder is connected to the extraction pump.

[0017] As a further optimized solution of the present invention, an electromagnetic rod arranged vertically is installed in the extraction cylinder.

[0018] As a further optimized solution of the present invention, the driving assembly includes a motor, a driving gear and a driven gear. The driven gear is fixedly sleeved on one end of the rotating pipe. The motor is installed at one end of the water tank and on one side of the rotary joint. The output end of the motor is connected to the driving gear meshing with the driven gear.

[0019] The above technical solution of the present invention has the following beneficial technical effects:

[0020] 1. In the present invention, the coolant in the filter cartridge is guided to the cooling water tank in the mold body through the circulation assembly and then flows back to itself to form a cycle. During this process, the stirring and aeration assembly in the filter cartridge is driven to rotate by the driving assembly, and the small round beads in the filter cartridge are sequentially guided into the circulation assembly. The small round beads are guided into the water tank in the mold body through the circulation assembly and then flow back into the filter cartridge to form a cycle. When the small round beads pass through the water tank in the mold body, they can scrape against the inner wall of the water tank to clean the impurities attached to the inner wall of the water tank. The above design can effectively prevent the shrinkage of the water tank flow channel caused by the long-term accumulation of impurities, thereby ensuring the heat absorption efficiency of the coolant for the products in the mold, avoiding the influence on the production efficiency due to the reduction of the cooling efficiency, ensuring that the product forming quality is not interfered by the problem of coolant impurity adhesion, and enabling the products to be stably produced according to the expected quality standards.

[0021] 2. After the small round beads clean the impurities in the water tank in the present invention, under the action of the circulation assembly, the impurities can flow back into the filter cartridge along with the coolant. Then, the gas can be guided into the stirring and aeration assembly through the air supply assembly and discharged through the stirring and aeration assembly to aerate in the filter cartridge. The aerated impurities float on the top surface of the filter cartridge, and the floating impurities can be extracted by the suction assembly. The above operations can separate and clean the impurities in the water tank from the coolant, avoid the repeated circulation of impurities in the cooling system, maintain the cleanliness of the coolant, extend the service life of the coolant, reduce the risk of cooling system failures caused by impurity problems, and reduce the maintenance cost.

[0022] 3. Since there is an electromagnetic rod inside the suction assembly, when cleaning the impurities intercepted in the filter cartridge, the electromagnetic rod can be powered on. After the electromagnetic rod is powered on, it can adsorb some metal impurities. After adsorbing the metal impurities, the electromagnetic rod is immediately powered off and then discharged. This design can specifically handle metal impurities and improve the cleaning effect. For those metal particle impurities that are difficult to clean by suction, the adsorption effect of the electromagnetic rod can effectively remove them, further enhancing the thoroughness of impurity cleaning in the entire cooling system, enabling the cooling system to operate more stably and efficiently, and providing a more reliable guarantee for the production process;

[0023] 4. In the traditional method of using a cleaning agent to clean the impurities in the mold water tank, the cleaning agent may corrode the inner wall of the mold. Especially some cleaning agents containing acidic or alkaline components, long-term use may cause damage to the inner wall of the mold, affecting the service life and precision of the mold. However, the present invention uses small round beads to physically scrape and clean the inner wall of the water tank without using chemical cleaning agents, avoiding the corrosion of the inner wall of the mold by chemical substances, thereby extending the service life of the mold, reducing the mold replacement cost, and ensuring that the precision and molding quality of the mold are not affected.

Detailed implementation manners

[0033] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0034] As Figure 1-8 shown, an aluminum alloy new energy vehicle sill beam mold proposed by the present invention includes a mold body 1, a water tank 2, a filter cartridge 3, a circulation assembly 4, an agitation and aeration assembly 5, a suction assembly 6, an air supply assembly 7 and a drive assembly 8;

[0035] The water tank 2 is installed at the bottom of the mold body 1, the filter cartridge 3 is arranged in the middle of the water tank 2, and the circulation assembly 4 is respectively communicated with the water tank in the mold body 1 and the filter cartridge 3 to circulate the coolant between the two;

[0036] The filter cartridge 3 is provided with an agitation and aeration assembly 5 and a plurality of small round beads 31, and the drive assembly 8 drives the agitation and aeration assembly 5 to rotate, and sequentially guides the small round beads 31 into the circulation assembly 4;

[0037] The air supply assembly 7 supplies air to the agitation and aeration assembly 5 to aerate in the filter cartridge 3, and the suction assembly 6 is communicated with the top of the filter cartridge 3 to extract the impurities after aeration.

[0038] When the mold body 1 of the present invention is working, the water tank 2 is used to store the coolant. The circulation component 4 is started to extract the coolant in the water tank of the mold body 1 and transport it to the filter cartridge 3, and then the processed coolant in the filter cartridge 3 is sent back to the water tank in the mold body 1 to realize the circulation of the coolant. The driving component 8 is started to drive the stirring and aeration component 5 to rotate, and the stirring plate 53 rotates accordingly. The small round beads 31 in the filter cartridge 3 are sequentially pushed to the circulation component 4. The small round beads 31 enter the water tank in the mold body 1 along with the coolant and scrape against the inner wall of the water tank during the flow process to clean the attached impurities, avoiding the reduction of the water tank flow channel caused by the accumulation of impurities, ensuring the heat absorption efficiency of the coolant for the products in the mold, and ensuring the product forming quality. The air supply component 7 supplies air to the stirring and aeration component 5, and the gas is aerated in the filter cartridge 3 through the aeration nozzles 54 on the aeration pipe 52 to make the impurities float. The suction component 6 is started to extract the floating impurities after aeration at the top of the filter cartridge 3 to maintain the cleanliness of the coolant and extend the service life of the coolant.

[0039] As Figure 4 shown in Figure 5 In this embodiment, the stirring and aeration component 5 includes a rotating pipe 51, an aeration pipe 52 and a stirring plate 53. The aeration pipe 52 is arranged in the filter cartridge 3 along its length direction. One end of the aeration pipe 52 is connected to the rotating pipe 51, and one end of the rotating pipe 51 is rotatably connected to the inner wall of one end of the water tank 2. A plurality of circumferentially arranged stirring plates 53 are installed on the rotating pipe 51. The rotating pipe 51 is driven to rotate by the driving component 8 and drives the stirring plate 53 to rotate accordingly. The small round beads 31 are sequentially pushed into the circulation component 4 by the stirring plate 53.

[0040] The driving component 8 drives the rotating pipe 51 to rotate, and the stirring plate 53 on the rotating pipe 51 rotates accordingly. During the rotation process, the stirring plate 53 sequentially pushes the small round beads 31 in the filter cartridge 3 into the circulation component 4. At the same time, the rotating pipe 51 drives the aeration pipe 52 to rotate, making the aeration more uniform, improving the aeration effect on the impurities in the coolant in the filter cartridge 3, and facilitating the floating of the impurities for subsequent suction and cleaning.

[0041] As Figure 5 shown in

[0042] The gas provided by the air supply component 7 enters the aeration pipe 52 through the rotating pipe 51 and then is discharged from the aeration nozzles 54 arranged at intervals on the aeration pipe 52 to form a uniform aeration effect in the filter cartridge 3. In this way, the impurities in the coolant can float more fully, which is convenient for the suction component 6 to extract and improves the impurity cleaning efficiency.

[0043] As Figure 4 shown in Figure 8As shown, in this embodiment, the air supply assembly 7 includes a rotary joint 71, an air supply pipe 72, and an air supply pump 73. One end of the rotating pipe 51 rotatably passes through one end of the water tank 2. The rotary joint 71 is installed at one end of the water tank 2. One end of the rotating pipe 51 is connected to the rotating air outlet end of the rotary joint 71. The air inlet end of the rotary joint 71 is connected to the air supply pipe 72. The air supply pump 73 is connected to the end of the air supply pipe 72 away from the rotary joint 71.

[0044] The air supply pump 73 transports gas through the air supply pipe 72 to the rotary joint 71. The rotating air outlet end of the rotary joint 71 is connected to the rotating pipe 51, enabling the gas to still stably enter when the rotating pipe 51 rotates, supplying gas to the aeration pipe 52. This structural design ensures the stability of the air supply, unaffected by the rotation of the rotating pipe 51, and ensures the continuous and stable progress of the aeration process in the filter cartridge 3.

[0045] As Figure 1 , Figure 2 and Figure 4 shown, in this embodiment, the circulation assembly 4 includes a return pipe 41 and a liquid supply component. The two ends of the return pipe 41 are respectively connected to the liquid outlet end of the mold body 1 and one side of the filter cartridge 3. The liquid supply component is respectively connected to the liquid inlet end of the mold body 1 and the other side of the filter cartridge 3.

[0046] The return pipe 41 transports the coolant at the liquid outlet end of the mold body 1 to the filter cartridge 3. The water supply pump 42 is started, and the coolant is extracted from the filter cartridge 3 through the water inlet pipe 421, and then the coolant is transported to the liquid inlet end of the mold body 1 through the water supply pipe 422, realizing the circulating flow of the coolant between the water tank in the mold body 1 and the filter cartridge 3, and ensuring that the coolant can continuously take away the heat of the product in the mold.

[0047] As Figure 4 shown, in this embodiment, the liquid supply component includes a water supply pump 42. The water supply pump 42 is installed on the side of the water tank 2. The liquid inlet end of the water supply pump 42 is connected to a water inlet pipe 421. One end of the water inlet pipe 421 is connected to the other side of the filter cartridge 3. The liquid outlet end of the water supply pump 42 is connected to a water supply pipe 422. The end of the water supply pipe 422 away from the water supply pump 42 is connected to the liquid inlet end of the mold body 1.

[0048] The water supply pump 42, as the power source of the liquid supply component, extracts the coolant from the filter cartridge 3 after being started. The water inlet pipe 421 connects the filter cartridge 3 and the water supply pump 42 and is responsible for transporting the coolant. The water supply pipe 422 transports the coolant output by the water supply pump 42 to the liquid inlet end of the mold body 1, ensuring the stable circulating power of the coolant and maintaining the normal operation of the cooling system.

[0049] As Figure 3 , Figure 5 , Figure 6 and Figure 7As shown in the figure, in this embodiment, the suction assembly 6 includes a suction cylinder 61 and a suction member. The suction cylinder 61 is installed on the top of the water tank 2, and the bottom end of the suction cylinder 61 is communicated with the top of the filter cartridge 3. The suction member is communicated with the suction cylinder 61.

[0050] When the suction member works, the impurities floating on the top after aeration in the filter cartridge 3 are collected through the suction cylinder 61, so as to separate the impurities from the coolant and keep the coolant clean.

[0051] As Figure 3 shown in the figure, in this embodiment, the suction member includes a suction pipe 62 and a suction pump 63. The top end of the suction cylinder 61 is connected with the suction pipe 62, and one end of the suction pipe 62 far away from the suction cylinder 61 is connected with the suction pump 63.

[0052] When the suction pump 63 starts to generate suction force, the impurities collected in the suction cylinder 61 are pumped out through the suction pipe 62. This structure is simple and efficient, can quickly and effectively clean the impurities in the filter cartridge 3, and prevent the impurities from mixing into the coolant again.

[0053] As Figure 7 shown in the figure, in this embodiment, a vertically arranged electromagnetic rod 64 is installed in the suction cylinder 61.

[0054] When the suction assembly 6 works, the electromagnetic rod 64 is powered on, and the electromagnetic rod 64 generates magnetism to adsorb the metal impurities in the filter cartridge 3. After the cleaning is completed, the power is cut off to discharge the adsorbed metal impurities, so as to clean the metal impurities specifically, improve the thoroughness of impurity cleaning, and ensure the stable operation of the cooling system.

[0055] As Figure 4 As Figure 8 shown in the figure, in this embodiment, the driving assembly 8 includes a motor 81, a driving gear 82 and a driven gear 83. The driven gear 83 is fixedly sleeved on one end of the rotating pipe 51. The motor 81 is installed at one end of the water tank 2 and on one side of the rotary joint 71. The output end of the motor 81 is connected with the driving gear 82 meshing with the driven gear 83.

[0056] When the motor 81 starts, the output end drives the driving gear 82 to rotate. The driving gear 82 meshes with the driven gear 83, thereby driving the driven gear 83 to rotate. The driven gear 83 is fixedly sleeved on the rotating pipe 51, and further drives the rotating pipe 51 to rotate, providing power for the stirring and aeration assembly 5, so that the small beads 31 can be pushed in sequence, realizing the cleaning of the impurities in the water tank of the mold body 1 and the aeration operation in the filter cartridge 3.

[0057] The specific working principle of the present invention is as follows:

[0058] When the mold is working, first, the water tank 2 stores the coolant. The water supply pump 42 in the circulation component 4 starts, extracts the coolant from the filter cartridge 3 through the water inlet pipe 421, and transports the coolant to the liquid inlet end of the mold body 1 through the water supply pipe 422. At the same time, the return pipe 41 transports the coolant at the liquid outlet end of the mold body 1 back to the filter cartridge 3 to realize the circulation of the coolant. The motor 81 of the driving component 8 starts, drives the driving gear 82 to rotate, the driving gear 82 drives the driven gear 83, so that the rotating pipe 51 rotates. The stirring plate 53 on the rotating pipe 51 sequentially pushes the small round beads 31 in the filter cartridge 3 into the circulation component 4. The small round beads 31 enter the water tank in the mold body 1 along with the coolant, scrape the inner wall of the water tank to clean impurities, and then return to the filter cartridge 3 along with the coolant. The air supply pump 73 of the air supply component 7 supplies air to the rotating pipe 51 through the air supply pipe 72 and the rotary joint 71. The gas is aerated in the filter cartridge 3 through the aeration nozzles 54 on the aeration pipe 52, so that the impurities float. The extraction pump 63 of the extraction component 6 extracts the impurities floating on the top of the filter cartridge 3 after aeration through the extraction pipe 62 and the extraction cylinder 61. If there are metal impurities, the electromagnetic rod 64 is electrified to adsorb them and then discharged after power-off. The whole process realizes the circulation of the coolant, the cleaning of the impurities in the water tank, and the separation of the impurities in the coolant, ensuring the cooling effect of the mold body 1 and the product forming quality, and prolonging the service life of the coolant and the mold body 1.

[0059] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
