Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle battery accessories, and in particular to a method and system for casting a thin-walled product all around. Background Art

[0002] New energy vehicle batteries are assembled through thin-walled parts with holes. Multiple battery assembly holes are densely distributed on the body of the thin-walled parts. The battery holes are adjacent to each other, so that a battery assembly hole distribution is formed on the body of the thin-walled parts, with a circle of battery assembly holes surrounding a piece of battery holes in the middle. To assemble batteries in the multiple battery assembly holes, aluminum liquid needs to be poured into the battery assembly holes. However, the wall thickness of the battery assembly hole of each battery assembly hole in the multiple battery assembly holes is only about 1 mm. It is very difficult to pour the battery holes in the battery assembly holes in a circle around the battery assembly holes, which is easy to cause pouring defects.

[0003] In summary, in the prior art, there is a technical problem that when pouring a battery hole around a thin-walled part, pouring is difficult and easily causes pouring defects.

[0004] Application Contents

[0007] The battery assembly holes on the thin-walled member are divided into surrounding battery assembly holes and a middle battery assembly hole, wherein the surrounding battery assembly holes surround the middle battery assembly hole, and the surrounding battery assembly holes and the middle battery assembly hole form a battery assembly hole pouring area on the thin-walled member, and the hole walls of adjacent battery assembly holes in all the battery assembly holes in the battery assembly hole pouring area are connected through connecting holes;

[0008] When pouring into the battery assembly holes in the pouring area of ​​the battery assembly holes, the middle battery assembly holes are selected for pouring, and the pouring liquid poured into the middle battery assembly holes radiates to the surroundings through the connecting holes and fills the surrounding battery assembly holes.

[0009] Furthermore, when pouring into the battery assembly holes in the pouring area of ​​the battery assembly holes, the pouring liquid poured into the middle battery assembly holes is aluminum liquid.

[0013] Furthermore, the stamping feeding assembly includes a shot cylinder and a punch; the shot cylinder is connected to the punch through a feeding pipe, and the punch is connected to the stamping feeding chamber; the shot cylinder shoots the casting liquid into the feeding pipe, and when the casting liquid flows through the punch, it is punched through the punch and enters the stamping feeding chamber.

[0014] Furthermore, the pouring time for the middle battery assembly hole is set as a first pouring time. When the first pouring time is reached, the pouring liquid poured into the middle battery assembly hole radiates to the surroundings through the connecting hole and fills the surrounding battery assembly holes.

[0015] Furthermore, when pouring into the middle battery assembly hole, the flow rate of the pouring liquid is set to a first pouring flow rate.

[0016] Furthermore, the hole wall thickness of the battery assembly holes on the four sides is 0.8 mm-1.2 mm, and the hole wall thickness of the battery assembly hole in the middle is 0.8 mm-1.2 mm.

[0017] In a second aspect, the present invention provides a system for casting thin-walled products all around, comprising:

[0018] A thin-walled member, wherein the battery assembly holes on the thin-walled member are divided into surrounding battery assembly holes and a middle battery assembly hole, wherein the surrounding battery assembly holes surround the middle battery assembly hole, and the surrounding battery assembly holes and the middle battery assembly hole form a battery assembly hole pouring area on the thin-walled member, wherein the hole walls of adjacent battery assembly holes in the battery assembly hole pouring area are connected through connecting holes;

[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in this embodiment will be clearly and completely described below in conjunction with the drawings in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] See also Figure 1-Figure 3 This embodiment provides a method for casting a thin-walled product all around, and the method for casting a thin-walled product all around includes the following steps:

[0033] S101, dividing the battery assembly holes on the thin-walled member into surrounding battery assembly holes and a middle battery assembly hole, wherein the surrounding battery assembly holes surround the middle battery assembly hole, and the surrounding battery assembly holes and the middle battery assembly hole form a battery assembly hole pouring area on the thin-walled member, wherein the hole walls of adjacent battery assembly holes in the battery assembly hole pouring area are connected through connecting holes;

[0034] S102, when pouring into the battery assembly holes in the pouring zone of the battery assembly holes, the middle battery assembly hole is selected for pouring, and the pouring liquid poured into the middle battery assembly hole radiates to the surroundings through the connecting holes and fills the surrounding battery assembly holes.

[0035] It should be noted that when pouring the battery assembly holes in the pouring area of ​​the battery assembly holes, the pouring liquid for pouring the middle battery assembly holes can be aluminum liquid. The hole wall thickness of the surrounding battery assembly holes is 0.8mm-1.2mm, and the hole wall thickness of the middle battery assembly hole is 0.8mm.

[0036] -1.2㎜.

[0037] It should be noted that, in this embodiment, by setting a connecting hole between adjacent battery assembly holes, the aluminum liquid can be injected through the middle battery assembly hole, and then flow radially from the middle battery assembly hole to the surrounding battery assembly holes in sequence, thereby avoiding the complexity of directly pouring each individual surrounding battery assembly hole independently. Since the wall thickness of the battery assembly hole is relatively thin (about 1mm), pouring each hole individually will increase the difficulty of operation and easily cause incomplete pouring or defects. The setting of the connecting hole allows the liquid aluminum to flow smoothly, ensures the uniformity of pouring, and reduces the possibility of pouring defects. In this embodiment, the middle battery assembly hole is poured first, rather than starting from the surrounding battery assembly holes. The choice of this pouring sequence is based on fluid dynamics considerations. By pouring the middle area first, the aluminum liquid will naturally flow to the surrounding areas. Under the action of gravity and pressure, the aluminum liquid diffuses to the surrounding battery assembly holes through the connecting hole, effectively filling the entire pouring area. Compared with pouring the surrounding battery assembly holes one by one, this method can reduce the complexity of controlling the flow path of the aluminum liquid and reduce the risk of failure during the pouring process. Since the aluminum liquid diffuses from the middle to the surroundings, the flow path is short and the flow resistance is small, thereby reducing the risk of uneven distribution of the aluminum liquid in the surrounding battery assembly holes or flow interruption. Pouring defects often arise from incomplete filling or uneven solidification in local areas. In this embodiment, the pouring speed and filling time can be better controlled through the design of the pouring path to avoid defects such as local premature solidification or incomplete filling.

[0038] In some preferred embodiments, when the middle battery assembly hole of the battery assembly hole pouring area is selected for pouring, the pouring liquid is poured into the middle battery assembly hole through a pouring device. Further, the pouring equipment includes a pouring runner and a pouring fluid injection supply mechanism; the pouring runner is aligned with the opening of the middle battery assembly hole and is connected to the pouring fluid injection supply mechanism; the pouring fluid injection supply mechanism supplies the pouring liquid to the pouring runner by injection, and the pouring liquid injected into the pouring runner enters the middle battery assembly hole through the opening of the middle battery assembly hole. Further, the pouring fluid injection supply mechanism includes a stamping feeding assembly and a stamping feeding chamber; the stamping feeding assembly is connected to the stamping feeding chamber, and the stamping feeding chamber is connected to the pouring runner; the stamping feeding assembly injects the pouring fluid into the stamping feeding chamber, and the pouring liquid enters the pouring runner through the stamping feeding chamber. Furthermore, the stamping feeding assembly includes a shot cylinder and a punch; the shot cylinder is connected to the punch through a feeding pipe, and the punch is connected to the stamping feeding chamber; the shot cylinder shoots the casting liquid into the feeding pipe, and the casting liquid is punched into the stamping feeding chamber through the punch when flowing through the punch. It should be noted that by setting a pouring flow channel and a pouring hydraulic injection supply mechanism, precise guidance and efficient delivery of the casting liquid can be achieved. The pouring flow channel is directly aligned with the middle battery assembly hole to ensure that the casting liquid can accurately enter the middle battery assembly hole. This design can prevent uneven casting caused by problems such as inaccurate pouring port position or flow channel blockage, and can also improve casting efficiency. The pouring hydraulic injection supply mechanism ensures that the casting liquid can be injected into the middle battery assembly hole in a uniform and continuous state by providing stable pressure and flow to the pouring flow channel. Especially in thin-walled parts with a wall thickness of only about 1 mm, it is crucial to control the casting pressure. This mechanism can adjust the flow rate and pressure of the liquid to avoid incomplete filling due to too low pouring pressure, or splashing and mold damage caused by too high pressure. The stamping feeding assembly can effectively and continuously deliver the pouring liquid to the pouring flow channel through the cooperation of the injection cylinder and the punch. The injection cylinder is responsible for providing pressure to push the pouring liquid into the punch through the feed pipe, and the punch evenly transfers the pressure to the pouring liquid in the feed chamber. This structural design can accurately control the flow rate and pressure of the pouring liquid, ensure that the pouring liquid is injected into the thin-walled parts at an appropriate speed, and prevent incomplete filling or defects caused by too fast or too slow injection. It can be understood that in this embodiment, through the design of the injection feeding assembly, the stamping feeding chamber and the flow channel, the entire pouring process can achieve a higher degree of automation and controllability. Every link in the pouring process, including pressure control, the path of liquid flow, and the adjustment of flow rate, can be accurately controlled by the equipment. This controllability is crucial for the casting of complex structures of thin-walled parts. It can effectively reduce human operation errors and improve production efficiency and product quality.The existence of the punching feed chamber can evenly distribute the pressure of the casting liquid before it enters the runner from the punch. This design not only ensures the uniformity of the flow of the casting liquid in the runner, but also avoids defects such as local casting liquid solidification and porosity caused by sudden pressure changes during the casting process. Through the coordination of the reasonably designed injection cylinder and punch, the stable flow of the casting liquid in the entire runner is ensured, and finally the uniform filling of the battery assembly holes in the middle and around is achieved.

[0039] In some preferred embodiments, the time for pouring into the middle battery assembly hole is set to the first pouring time. When the first pouring time is reached, the pouring liquid poured into the middle battery assembly hole radiates to the surroundings through the connecting hole and fills the surrounding battery assembly holes. Further, when pouring into the middle battery assembly hole, the flow rate of the pouring liquid is set to the first pouring flow rate. When the first pouring time is reached, the pouring liquid poured into the middle battery assembly hole at the first pouring flow rate radiates to the surroundings through the connecting hole and fills the surrounding battery assembly holes. It should be noted that in this embodiment, by setting the first pouring time and the first pouring flow rate, it can be ensured that the liquid metal has enough time to diffuse to the surroundings through the connecting hole after entering the middle battery assembly hole, and fills at a suitable flow rate. This control can prevent the pouring liquid from filling the surrounding battery assembly holes too quickly or too slowly, thereby reducing casting defects, such as incomplete filling, cold shut and other problems. If the pouring time is unreasonable, the liquid metal may solidify too quickly due to uneven solidification when filling the middle hole, thereby affecting the radiation diffusion to the surrounding holes. By reasonably setting the first pouring time and flow rate, it is possible to ensure that the pouring liquid maintains appropriate fluidity during the diffusion process and prevent pouring defects caused by uneven solidification. In addition, since the pouring liquid of the central battery assembly hole is radiated to the surrounding battery holes through the connecting hole in the design, it is necessary to ensure that the flow rate is moderate to prevent local blockage or incomplete filling of the liquid metal when flowing through the connecting hole. A reasonable pouring flow rate can cause the pouring liquid to diffuse evenly and smoothly to the surrounding battery assembly holes, avoiding fluctuations or discontinuities during the filling process. In addition, controlling the first pouring time and flow rate can realize the automation and standardization of the pouring process, thereby improving production efficiency. By accurately adjusting the time and flow rate, manual intervention can be reduced, while ensuring the quality consistency of each product and avoiding product defects caused by improper operation. Exemplarily, assuming that the total pouring area of ​​the central battery assembly hole and the surrounding battery assembly holes is larger, and the flow path of the pouring liquid is longer, the first pouring time can be set to 3 seconds. This means that after the pouring liquid enters the central battery assembly hole, it takes 3 seconds to diffuse through the connecting holes to the surrounding battery assembly holes. This time can ensure that the liquid metal is smoothly radiated to the surrounding holes while maintaining a certain fluidity. Assuming that in order to avoid splashing of the pouring liquid due to excessive flow rate or incomplete filling due to too slow flow rate, the first pouring flow rate can be set to 0.5 meters per second. This means that the flow rate of the pouring liquid when entering the central battery assembly hole is 0.5 meters per second, which can ensure that the liquid metal flows stably and evenly, and can be moderately diffused to the surrounding battery assembly holes through the connecting holes, avoiding pouring problems caused by excessively high or low flow rates.

[0040] See also Figure 3In some further preferred embodiments, when pouring the thin-walled part 1, the pouring channel includes a main channel 2 and at least two branch channels 3; one end of the main channel is connected to the pouring liquid injection supply mechanism, and the other end of the main channel is respectively connected to the at least two branch channels, and the at least two branch channels are respectively aligned with the openings of different central battery assembly holes in the central battery assembly hole; when the pouring liquid injection supply mechanism supplies the pouring liquid to the pouring channel, the pouring liquid enters the main channel through the at least two branch channels and respectively enters the openings of different central battery assembly holes in the central battery assembly hole. Further, in the at least two branch channels, each branch channel includes a plurality of feed heads 30, and each feed head is aligned with the openings of different central battery assembly holes in the central battery assembly hole. It should be noted that in this embodiment, the main channel is connected to the branch channels, so that the liquid metal can be evenly distributed from the main channel to the plurality of branch channels. This design ensures that multiple central battery assembly holes can receive the pouring liquid at the same time, rather than pouring them one by one. Since time and temperature control during the pouring process is crucial to ensure uniform pouring, the setting of multiple branch flow channels reduces the time difference of pouring a single hole one by one, so that all battery assembly holes can be poured synchronously, avoiding the problem of uneven solidification or unfilled holes caused by the pouring time difference. Further, by setting multiple feed heads in each branch flow channel, the liquid metal can be injected into different central battery assembly holes faster and more evenly. Such a design increases the speed of the overall pouring and reduces the production cycle. At the same time, since each feed head is precisely aligned with the opening of different battery assembly holes, it can effectively avoid the solidification problem caused by the long path of the liquid metal when it flows through the branch flow channel, ensuring that the liquid metal enters the assembly hole under appropriate fluidity, and reducing casting defects such as cold shut and incomplete filling. In addition, by setting the main channel and at least two branch flow channels, the flow path of the pouring liquid is precisely designed, which can avoid the problem of uneven fluid resistance in a longer pouring path. When the liquid metal enters the branch flow channel from the main flow channel, the flow is evenly transferred to different feed heads to ensure that the liquid metal can flow into each battery assembly hole quickly and stably. This optimized flow path design reduces the retention of liquid metal in the branch flow channel, maintains its appropriate flow rate, and is conducive to improving the casting effect. In addition, when the liquid metal flows through the long flow channel, it usually causes pressure loss due to the friction resistance in the flow channel, which in turn affects the subsequent casting effect. By dividing the main flow channel into multiple branch flow channels, the length of each branch flow channel is shortened, thereby reducing the pressure loss of liquid metal when it flows through. At the same time, since each branch flow channel has multiple feed heads that can directly align with the opening of the middle battery assembly hole, the adverse effects of pressure attenuation during the casting process are further reduced, ensuring that the casting liquid can enter the battery assembly hole at a stable pressure and speed. In addition, the design of multiple branch flow channels and feed heads provides greater flexibility and modular structure for casting equipment.By adjusting the number of different branch channels or the alignment of the feed head, the equipment can adapt to the casting needs of thin-walled battery assembly holes of different sizes, hole numbers and distributions. This design not only improves the versatility of the equipment, but also allows for flexible adjustment according to different production needs, improving the adaptability and efficiency of the production line.
