Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy battery pack parts production, in particular to a casting die for producing aluminum alloy battery pack parts. Background Art

[0002] A die-casting mold is a tool used to cast metal parts. It is performed on a dedicated die-casting forging machine. The basic die-casting process involves molten metal being poured into the die cavity at a low or high speed. The mold has a movable cavity surface, which is pressurized as the molten metal cools. This eliminates shrinkage defects in the blank and achieves a forged, broken grain structure within the blank. This significantly improves the overall mechanical properties of the blank.

[0003] In the above-mentioned prior art, the die-cast products of aluminum alloy battery pack shells that are prone to sticking film are prone to shrinkage instability, sticking film pulling aluminum, etc. during the production process, resulting in problems such as easy deformation of parts and unqualified dimensions. In the face of these problems, the mold mostly adopts a design of adding a push rod to the inner side of the product. Although the push rod is added to the inner side of the product to eject, it can effectively solve the sticking film problem, but it is easy to cause deformation of the product ejection surface and other problems. In addition, customers have higher and higher requirements for product quality. Due to assembly and other reasons, the inner side of the product is not allowed to have push rod marks, cloak burrs, etc. This solution cannot be used. Therefore, it is necessary to design a casting mold for the production of aluminum alloy battery pack parts that will not cause deformation of the parts and sticking film when the cast parts are removed. Utility Model Content

[0004] In order to solve the technical problems that die-cast products of aluminum alloy battery pack shells that are prone to sticking to the film are prone to unstable shrinkage, sticking to the film and pulling aluminum during the production process, which leads to easy deformation of parts and unqualified dimensions, the utility model provides a casting die for the production of aluminum alloy battery pack parts.

[0005] The present utility model is implemented by the following technical solutions: a casting mold for producing aluminum alloy battery pack parts, including a battery pack shell casting mold, one side of the battery pack shell casting mold is provided with a flow channel for injection molding, one side of the battery pack shell casting mold is provided with a first force component that provides force to the battery pack shell casting mold, one side of the first force component is provided with a second force component that provides force to the flow channel, the other side of the first force component is provided with a first moving component that drives the first force component to move, and one side of the first moving component is provided with a second moving component that drives the second force component to move.

[0006] Through the above technical solution, when it is necessary to take out the cast aluminum alloy battery pack housing product with an easy-to-adhere film, two moving components are used to move the two acting components separately, so that there is always an acting force on the battery pack housing casting mold, ensuring that the mold will not deform due to the rapid loss of the acting force, resulting in shrinkage and mucosal deformation of the product.

[0007] As a further improvement of the above solution, the first acting component includes a side extrusion block arranged on one side of the battery pack housing casting mold, a slider seat fixedly installed on one side of the side extrusion block, and two limit blocks installed on one side of the slider seat. A pushing groove is formed on one side of the slider seat.

[0008] Through the above technical solution, the side extrusion block will always generate a pulling force on the battery pack housing casting mold, preventing the product in the battery pack housing casting mold from shrinking and mucosal deformation.

[0009] As a further improvement of the above solution, the second acting component includes a pushing block arranged on one side of the runner, two connecting rods fixedly installed on one side of the pushing block, and a pressing block fixedly installed at one end of the two connecting rods.

[0010] Through the above technical solution, after the side extrusion block is slowly withdrawn, the pushing block will continue to pull the runner, so that the runner continues to provide an acting force on the battery pack housing casting mold.

[0011] As a further improvement of the above solution, the first moving component includes an oil cylinder arranged on one side of the slider seat, a connecting column fixedly installed on the pushing end of the oil cylinder, and a fixing plate fixedly installed on one side of the oil cylinder for fixing the oil cylinder. The fixing plate is arranged in a "U" shape, and one end of the connecting column extends into the pushing groove of the slider seat.

[0012] Through the above technical solution, the oil cylinder cooperates with the connecting column to move the slider seat and provide an acting force on the battery pack housing casting mold, preventing the internal product from shrinking and mucosal deformation during the casting process of the mold.

[0013] As a further improvement of the above solution, a bottom plate is sleeved on the outer surface of the connecting column. One side of each of the two limit blocks is fixedly installed with a first guide post whose one end is fixedly installed with the bottom plate, and two second guide posts whose one ends are fixedly installed with the bottom plate are fixedly installed on one side of the slider seat.

[0014] Through the above technical solution, the bottom plate cooperates with the first guide post and the second guide post to be fixedly connected with the limit block and move together with the slider seat.

[0015] As a further improvement of the above scheme, the second moving component includes a mounting plate sleeved on the connecting column and a limiting plate arranged on one side of the mounting plate and sleeved on the connecting column. The limiting plate and the mounting plate are both slidably matched with multiple first guide columns and multiple second guide columns. Multiple first guide columns and multiple second guide columns are each sleeved with a disc spring at one end connected to the base plate and the other end connected to the mounting plate. One side of the mounting plate and the limiting plate is provided with a fixing groove adapted to the connecting rod.

[0016] Through the above technical solution, after the first force component moves, the second moving component will allow the first force component to continue to provide force to the battery pack shell casting mold to prevent the force from being withdrawn too quickly and causing the product to shrink and deform.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model sets a first force component, a second force component, a first moving component and a second moving component. The first force component and the second force component will squeeze the battery pack shell casting mold to provide a force effect. When the battery pack shell casting mold product that is easy to stick to the film is taken out, the first moving component will make the first force component move first to remove the force, and then the second moving component will make the second force component move again to remove the force. In this way, the force is divided into two parts for removal, which can avoid removing too much force at one time, resulting in insufficient force of the mold to cause deformation, causing the internal product to shrink and deform the film, so as to ensure that there will be no sticking and deformation when the product is taken out.

[0024] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Please combine Figure 1-Figure 3 , a casting die for producing aluminum alloy battery pack parts in this embodiment includes a battery pack shell casting die 1, a runner 2 for injection molding is provided on one side of the battery pack shell casting die 1, a first force component for providing force to the battery pack shell casting die 1 is provided on one side of the battery pack shell casting die 1, a second force component for providing force to the runner 2 is provided on one side of the first force component, a first moving component for driving the first force component to move is provided on the other side of the first moving component, and a second moving component for driving the second force component to move is provided on one side of the first moving component.

[0026] Combine Figure 1 and Figure 3 The first force component includes a side extrusion block 301 arranged on one side of the battery pack shell casting mold 1, a slider seat 302 fixedly installed on one side of the side extrusion block 301, and two limit blocks 303 installed on one side of the slider seat 302. A pushing groove is provided on one side of the slider seat 302. The second force component includes a pushing block 401 arranged on one side of the flow channel 2, two connecting rods 402 fixedly installed on one side of the pushing block 401, and a pressure block 403 fixedly installed at one end of the two connecting rods 402. After the side extrusion block 301 is slowly withdrawn, the pushing block 401 will continue to act on the flow channel, allowing the flow channel to continue to provide force on the battery pack shell casting mold 1.

[0027] Combine Figure 1-Figure 3, the first moving component includes an oil cylinder 501 arranged on one side of the slider seat 302, a connecting column 502 fixedly installed on the pushing end of the oil cylinder 501, and a fixing plate 503 fixedly installed on one side of the oil cylinder 501 for fixing the oil cylinder 501. The fixing plate 503 is arranged in a "U" shape. One end of the connecting column 502 extends into the pushing groove of the slider seat 302. A bottom plate 7 is sleeved on the outer surface of the connecting column 502. One side of each of the two limiting blocks 303 is fixedly installed with a first guide post 8 whose one end is fixedly installed with the bottom plate 7. One side of the slider seat 302 is fixedly installed with two second guide posts 9 whose one ends are fixedly installed with the bottom plate 7. The second moving component includes a mounting plate 601 sleeved on the connecting column 502 and a limiting plate 602 arranged on one side of the mounting plate 601 and sleeved on the connecting column 502. The limiting plate 602 and the mounting plate 601 are both in sliding fit with a plurality of first guide posts 8 and a plurality of second guide posts 9. A disc spring 10 whose one end is connected to the bottom plate 7 and the other end is connected to the mounting plate 601 is sleeved on each of the plurality of first guide posts 8 and the plurality of second guide posts 9. Fixing grooves adapted to the connecting rod 402 are formed on one side of the mounting plate 601 and the limiting plate 602. After the first acting force component moves, the second moving component will enable the first acting force component to continue to exert an acting force on the battery pack housing casting die 1, preventing the product from shrinking and deforming due to the too-fast withdrawal of the acting force.

[0028] The implementation principle of a casting die for producing aluminum alloy battery pack parts in the embodiment of the present application is as follows: after the casting and pressing of the aluminum alloy battery pack parts, the die-casting action is completed. When the movable fixed mold is opened, the movable mold lateral oil cylinder 501 has not yet started. Under the action of the side extrusion block 301 and the push block 401, the product will not be brought out with the fixed mold, and the product itself and the runner 2 will be subjected to the action force. There are many force points and they are balanced. The overall force is basically stable and the product will basically not be deformed. After the movable fixed mold is fully opened, the robot grabs the material handle. At this time, the product is still in the mold cavity and the product is stable as a whole. Then, under the action of the oil cylinder 501, the connecting column 502 will move, driving the side extrusion block 301, the slider seat 302 and the two limit blocks 303 to move backward. Since the bottom plate 7 is connected to the multiple second guide columns 9 through multiple first guide columns 8, the bottom plate 7 will also move backward, and the mounting plate 601 and the bottom plate 7, the disc spring 10 between them is also loosened, the mounting plate 601 and the limit plate 602 are screwed and connected, and slide with multiple first guide pillars 8 and multiple second guide pillars 9, so the mounting plate 601 and the limit plate 602 will not move temporarily, and the push block 401, connecting rod 402 and pressure block 403 connected thereto will not move either. At this time, the flow channel 2 is still held by the push block 401, providing a force for the battery pack shell casting mold 1, and the overall state of the part is stable, which will reduce the effect of the dimensional change of the external shape caused by the extraction of the side extrusion block 301. After the side extrusion block 301 is completely separated from the product shape, the first guide pillar 8 and the limit block 303 slide to the bottom, the limit block 303 will push the first guide pillar 8 to move, thereby driving the push block 401, the connecting rod 402 and the pressure block 403 to move backward as a whole. At this time, the part is completely separated from the cavity, and the robot takes the part away.

[0029] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
