Description

Technical Field

[0001] This invention relates to the technical field of die-casting molds, and in particular to an LED lamp, a battery box, and a die-casting mold thereof. Background Technology

[0002] Die casting molds are tools used to cast metal parts, and also tools used to complete the die casting process on specialized die casting and forging machines. Die castings generally have requirements for appearance and density. If the gas inside the molding cavity cannot be removed in time during die casting, the air will seep into the molten metal, causing bubbles to easily form on the surface of the die-cast product, affecting its appearance quality. Simultaneously, it makes the die-cast product prone to internal porosity, affecting its internal density and leading to a decrease in strength.

[0003] In traditional techniques, venting assemblies are commonly used to vent air from die-casting molds. These venting assemblies include a first venting block and a second venting block, which are positioned opposite each other to form an venting channel communicating with the molding cavity. However, the first and second venting blocks are prone to blockage of the venting channel due to installation inaccuracies. This prevents air from being expelled from the molding cavity in a timely manner, leading to a decrease in the external quality and strength of the die-cast product. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an LED lamp, a battery box and its die-casting mold.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A die-casting mold, comprising:

[0007] A fixed mold assembly includes a fixed mold fixing component and a cavity component, wherein the cavity component is embedded in the fixed mold fixing component;

[0008] The moving mold assembly includes a moving mold fixing component and a core component, wherein the core component is embedded in the moving mold fixing component, and the core component and the cavity component are closed to form a sequentially connected feeding channel, a molding cavity, an overflow cavity and a first venting channel;

[0009] The venting assembly includes a first venting block, a second venting block, and a closing guide. The first venting block is fixedly connected to the fixed mold fixing member and is disposed adjacent to the cavity member. The second venting block is loosely connected to the moving mold fixing member and is disposed adjacent to the core member. The second venting block has a closing guide hole. One end of the closing guide is fixedly connected to the first venting block, and the other end of the closing guide is movably inserted into the closing guide hole, so that the first venting block and the first venting block close together to form a second venting channel communicating with the first venting channel.

[0010] In one embodiment, the moving mold fixing member has a connecting hole, and the second vent block has a countersunk hole and a clearance hole that are connected to each other; the die casting mold also includes a loosening pre-fitting member, which passes through the clearance hole and has a gap between the loosening pre-fitting member and the clearance hole. The first end of the loosening pre-fitting member is threaded into the connecting hole, and the second end of the loosening pre-fitting member is located in the countersunk hole and has a gap with the groove wall of the countersunk hole, so that the second vent block is loosely connected to the moving mold fixing member.

[0011] In one embodiment, the die-casting mold further includes an elastic connector, which is connected to the moving mold fixing member and the second venting block respectively, so that the second venting block is loosely connected to the moving mold fixing member.

[0012] In one embodiment, the first exhaust block has an exhaust groove, and the second exhaust block has an exhaust protrusion, the exhaust protrusion being located within the exhaust groove and forming the second exhaust channel.

[0013] In one embodiment, the die-casting mold further includes a core-pulling mechanism that abuts against one side of the core when the core and the cavity are closed.

[0014] In one embodiment, the core-pulling mechanism includes an inclined guide post and a sliding member. The first end of the inclined guide post is fixedly connected to the fixed mold fixing member, and the inclined guide post is inclined to the closing direction of the core and the cavity. The sliding member is slidably connected to the moving mold fixing member, and the sliding member has an inclined guide hole. The second end of the inclined guide post is slidably inserted into the inclined guide hole, so that the core-pulling mechanism abuts against one side of the core when the core and the cavity are closed.

[0015] In one embodiment, the core-pulling mechanism further includes a limiting member connected to one side of the moving mold fixing member and disposed opposite to the sliding member. After the inclined guide post separates from the inclined guide hole, the limiting member abuts against the sliding member.

[0016] In one embodiment, the die-casting mold further includes an ejector assembly connected to the moving mold fixing member on the side opposite to the fixed mold fixing member, the ejector assembly being used to eject the die-cast product.

[0017] A battery box is obtained using the die-casting mold described in any of the above embodiments.

[0018] An LED light, including the aforementioned battery box.

[0019] Compared with the prior art, the present invention has at least the following advantages:

[0020] 1. Because the second vent block is loosely connected to the moving mold fixing component, its position is adjustable after installation. Since one end of the closing guide is fixedly connected to the first vent block, and the other end is movably inserted into the closing guide hole of the second vent block, the closing guide adjusts the position of the second vent block, thus guiding it to correctly align the first and second vent blocks and form the second vent channel. This avoids blockage of the second vent channel, preventing porosity on the surface of the die-cast product and improving its appearance quality (surface flatness). Simultaneously, it prevents internal porosity, thereby increasing the strength of the die-cast product.

[0021] 2. Because the first vent block and the second vent block are correctly aligned, the fitting accuracy between the second vent block and the moving mold fixing part is improved, and the problem of molten metal leakage through the gap between the second vent block and the moving mold fixing part is avoided.

[0022] 3. Since the second exhaust block can be guided by inserting the closed guide member into the closed guide hole of the second exhaust block, the installation requirements of the second exhaust block are reduced, thereby improving the installation efficiency of the second exhaust block.

[0031] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] This application provides a die-casting mold, including a fixed mold assembly, a moving mold assembly, and a venting assembly. The fixed mold assembly includes a fixed mold fixing member and a cavity member, the cavity member being embedded in the fixed mold fixing member. The moving mold assembly includes a moving mold fixing member and a core member, the core member being embedded in the moving mold fixing member. The core member and the cavity member are closed to form a sequentially connected feed channel, a forming cavity, an overflow cavity, and a first venting channel. The venting assembly includes a first venting block, a second venting block, and a closing guide member. The first venting block is fixedly connected to the fixed mold fixing member and is adjacent to the cavity member. The second venting block is loosely connected to the moving mold fixing member and is adjacent to the core member. The second venting block has a closing guide hole. One end of the closing guide member is fixedly connected to the first venting block, and the other end of the closing guide member is movably inserted into the closing guide hole, so that the first venting block and the first venting block are closed to form a second venting channel communicating with the first venting channel.

[0035] In the aforementioned die-casting mold, the second vent block is loosely connected to the moving mold fixing component, allowing its position to be adjusted after installation. Since one end of the closing guide is fixedly connected to the first vent block, and the other end is movably inserted into the closing guide hole of the second vent block, the closing guide adjusts the position of the second vent block, ensuring correct alignment between the first and second vent blocks and forming a second venting channel. This prevents blockage of the second venting channel, thus avoiding porosity on the surface of the die-cast product and improving its appearance quality (surface flatness). Simultaneously, it prevents internal porosity, thereby increasing the product's strength. Correct alignment of the first and second vent blocks improves the fit accuracy between the second vent block and the moving mold fixing plate, preventing molten metal leakage through the gap between them. Furthermore, the closing guide inserted into the closing guide hole of the second vent block aligns it, reducing installation requirements and improving installation efficiency.

[0036] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0037] like Figures 1 to 4As shown, a die-casting mold 10 of one embodiment includes a fixed mold assembly 100, a moving mold assembly 200, and a venting assembly 300. The fixed mold assembly 100 includes a fixed mold fixing member 110 and a cavity member 120. The cavity member 120 is embedded in the fixed mold fixing member 110 so that the fixed mold fixing member 110 fixes the cavity member 120. The moving mold assembly 200 includes a moving mold fixing member 210 and a core member 220. The core member 220 is embedded in the moving mold fixing member 210 so that the moving mold fixing member 210 fixes the core member 220 and simultaneously causes the moving mold fixing member 210 to drive the core member 220 to move, so that the core member 220 closes and separates from the cavity member 120. The core component 220 and the cavity component 120 are closed to form a sequentially connected feeding channel 221, forming cavity 222, overflow cavity 223 and first exhaust channel 224. The molten metal, i.e., the molten metal, enters the forming cavity 222 through the feeding channel 221 and is formed. The molten metal that enters the forming cavity 222 first is cooled and formed in the overflow cavity 223. The air in the forming cavity 222 is exhausted through the first exhaust channel 224.

[0038] like Figures 2 to 4 As shown, the venting assembly 300 further includes a first venting block 310, a second venting block 320, and a closing guide 330. The first venting block 310 is fixedly connected to the fixed mold fixing member 110 and is disposed adjacent to the cavity member 120. The second venting block 320 is loosely connected to the moving mold fixing member 210 and is disposed adjacent to the core member 220. The second venting block 320 has a closing guide hole 321. One end of the closing guide 330 is fixedly connected to the first venting block 310, and the other end of the closing guide 330 is movably inserted into the closing guide hole 321, so that the first venting block 310 and the first venting block 320 are closed to form a second venting channel 301 communicating with the first venting channel 224. The air in the molding cavity 222 is discharged to the outside of the die-casting mold 10 through the overflow cavity 223, the first venting channel 224, and the second venting channel 301 in sequence. In this embodiment, the second vent block 320 is loosely connected to the moving mold fixing member 210, that is, after the second vent block 320 is connected to the moving mold fixing member 210, it can still move relative to the moving mold fixing member 210 so that the closing guide member 330 can be inserted into the closing guide hole 321 and correct the second vent block 320, that is, so that the closing guide member 330 moves the second vent block 320 to the correct position.

[0039] In the aforementioned die-casting mold 10, the second venting block 320 is loosely connected to the moving mold fixing member 210, allowing its position to be adjusted after installation. Since one end of the closing guide member 330 is fixedly connected to the first venting block 310, and the other end is movably inserted into the closing guide hole 321 of the second venting block 320, the closing guide member 330 adjusts, or guides, the position of the second venting block 320, ensuring correct alignment between the first venting block 310 and the second venting block 320 and forming the second venting channel 301. This avoids blockage of the second venting channel 301, preventing porosity on the surface of the die-casting product and improving its appearance quality (i.e., surface flatness). Simultaneously, it prevents internal porosity, thereby increasing the strength of the die-casting product. Because the first vent block 310 and the second vent block 320 are correctly aligned, the fitting accuracy between the second vent block 320 and the moving mold fixing member 210 is improved, avoiding leakage of molten metal through the gap between the second vent block 320 and the moving mold fixing member 210. Furthermore, since the second vent block 320 can be aligned by inserting the closing guide member 330 into the closing guide hole 321 of the second vent block 320, the installation requirements of the second vent block 320 are reduced, thereby improving the installation efficiency of the second vent block 320.

[0040] In one embodiment, the moving mold fixing member 210 has a connecting hole, and the second vent block 320 has a countersunk hole and a clearance hole that are connected to each other; the die casting mold also includes a loosening pre-fitting member, which passes through the clearance hole and has a gap between it and the clearance hole. The first end of the loosening pre-fitting member is threaded into the connecting hole, and the second end of the loosening pre-fitting member is located in the countersunk hole and has a gap with the groove wall of the countersunk hole, so that the second vent block 320 is loosely connected to the moving mold fixing member 210. In this embodiment, the connecting hole is a threaded hole, and the countersunk hole and the clearance hole are all smooth holes, meaning the walls of the countersunk hole and the clearance hole are both smooth. The loosening pre-fitting component is sequentially inserted into the countersunk hole, the clearance hole, and the connecting hole. One end of the loosening pre-fitting component is located in the connecting hole and threadedly connected to the moving mold fixing member 210, while the other end is located in the countersunk hole. There is a gap between the loosening pre-fitting component and the wall of the countersunk hole, and also a gap between the loosening pre-fitting component and the clearance hole. This allows the loosening pre-fitting component to pre-fix the second vent block 320, while simultaneously allowing the second vent block 320 to move relative to the moving mold fixing member 210. This enables the closing guide member 330 to guide the second vent block 320, thereby improving the correct closure of the second vent block 320 and the first vent block 310 to form the second vent groove 311, avoiding the problem of blockage in the second vent channel 301. It can be understood that the loosening pre-fitting component can be a screw, self-tapping screw, wood screw, or other existing headed fasteners.

[0041] like Figure 4 and Figure 5 As shown, in one embodiment, the die-casting mold 10 further includes an elastic connector 400, which is connected to the moving mold fixing member 210 and the second vent block 320 respectively, so that the second vent block 320 is loosely connected to the moving mold fixing member 210. In this embodiment, the elastic connector 400 is an elastic structure, that is, the elastic connector 400 can deform under force. The second vent block 320 is elastically connected to the moving mold fixing member 210 through the elastic connector 400, so that the second vent block 320 can be displaced under force. This allows the closing guide member 330 to be inserted into the closing guide hole 321 of the second vent block 320 to guide the second vent block 320, thereby making the first vent block 310 and the second vent block 320 face each other and form the second vent channel 301, avoiding the problem of blockage of the second vent channel 301. It can be understood that the elastic connector 400 can be a spring, a silicone pad, a rubber pad, or other existing elastic structures.

[0042] like Figure 5 As shown, in one embodiment, the first exhaust block 310 has an exhaust groove 311, and the second exhaust block 320 has an exhaust protrusion 321. The exhaust protrusion 321 is located within the exhaust groove 311 and forms the second exhaust channel 301. In this embodiment, the first exhaust block 310 and the second exhaust block 320 are closed to form the second exhaust channel 301, that is, the exhaust protrusion 321 is located within the exhaust groove 311, and there is a gap between the exhaust protrusion 321 and the groove wall of the exhaust groove 311, so that the first exhaust block 310 and the second exhaust block 320 are positioned to form the second exhaust channel 301.

[0043] It is understandable that after the molten metal in the die-casting mold 10 cools and solidifies, the die-cast product in the forming cavity 222, the waste in the overflow cavity 223, the waste in the first venting channel 224, and the waste in the second venting channel 301 are sequentially connected, causing a large amount of waste to fix the die-cast product inside the die-casting mold 10, thus making it difficult to remove the die-cast product from the forming cavity. To improve the ease of removing the die-cast product, such as... Figure 5As shown, in one embodiment, the second exhaust block 320 has a communicating knife groove 322 and a receiving cavity 323, wherein the knife groove 322 is also communicating with the second exhaust channel 301, and the second exhaust block 320 also has a telescopic hole 324, which is communicating with the receiving cavity 323. The exhaust assembly 300 further includes a cutting blade 340, a blade connector 350, an elastic element 360, and an extension 370. The cutting blade 340 is slidably disposed within the blade groove 322 and is used to cut waste material within the second exhaust channel 301. One end of the blade connector 350 is connected to the cutting blade 340, and the blade connector 350 is slidably and rotatably connected within the receiving cavity 323. The elastic element 360 is disposed within the receiving cavity 323, with one end connected to the other end of the blade connector 350, and the other end abutting against the groove wall of the receiving cavity 323. One end of the extension 370 is connected to the blade connector 340. The connector 350 is adjacent to one end of the elastic element 360, and the protrusion 370 and the elastic element 360 are respectively located on opposite sides of the blade connector 350. The other end of the protrusion 370 extends out of the telescopic hole 324 and abuts against the moving mold fixing member 210 when the core 220 and the cavity 120 are closed, so that the protrusion 370 pushes the blade connector 350 to rotate and slide, thereby causing the cutting blade 340 to be completely retracted into the blade groove 322. When the core 220 and the cavity 120 are closed, the elastic element 360 pushes the blade connector 350 to rotate and slide, so that the cutting blade 340 enters the second exhaust channel 301 and cuts the waste.

[0044] In this embodiment, the sprue groove 322 is adapted to the cutting blade 340 to suppress the flow of molten metal into the sprue groove 322. The sprue groove 322 is connected to the second venting channel 301 so that the cutting blade 340, which is slidably disposed in the sprue groove 322, can slide into the second venting channel 301. When the core part 220 and the cavity part 120 are closed, the second venting block 320 is aligned with the first venting block 310. At the same time, the protrusion 370 abuts against the moving mold fixing member 210 through the telescopic hole 324, so as to push the end of the blade connector 350 away from the cutting blade 340 to rotate away from the moving mold fixing member 210. At the same time, it pushes the blade connector 350 to slide away from the cutting blade 340, thereby making the cutting blade 340 completely retract into the sprue groove 322, so as to prevent the cutting blade 340 from entering the second venting channel 301, thereby avoiding the problem of the cutting blade 340 obstructing the venting of the second venting channel 301, that is, ensuring the normal venting of the second venting channel 301. After the molten metal in the molding cavity 222 cools and solidifies, the core part 220 and the cavity part 120 separate, causing the first venting block 310 to separate from the second venting block 320. At this time, the elastic element 360 pushes the blade connector 350 to rotate towards the moving mold fixing part 210 at the end away from the cutting blade 340, and simultaneously pushes the blade connector 350 to slide towards the cutting blade 340, causing more protruding parts 370 to extend out from the telescopic hole 324. At the same time, the cutting blade 340 slides along the cutting groove 322 to the second venting channel 301 and cuts the waste, thereby reducing the maximum adhesion force of the waste and improving the convenience of ejecting the die-cast product and waste. In one embodiment, the elastic element 360 is a spring. Of course, in other embodiments, the elastic element 360 can also be a silicone part, a rubber part, or an existing gas elastic element.

[0045] like Figure 5As shown, in one embodiment, the cutting blade 340 includes a blade body 341 and a fastening portion 342. The blade body 341 is slidably disposed within the blade groove 322 and is used to cut waste material within the second exhaust channel 301. The fastening portion 342 has external threads. One end of the fastening portion 342 is located in the blade groove 322 and connected to the side of the blade body 341 adjacent to the blade connector 350. The other end of the fastening portion 342 is located in the receiving cavity 323 and is threadedly connected to the blade connector 350. Further, the blade connector 350 has a threaded hole 352 at one end adjacent to the blade groove 322, and the end of the blade connector 350 facing away from the blade body 341 is located in the threaded hole 352 and threadedly connected to the blade connector 350. Since the space inside the second exhaust block 320 is small, it is not conducive to the connection between the cutting blade 340 and the blade connector 350. Therefore, in this embodiment, the cutting blade 340 includes a blade body 341 and a fastening part 342. The blade body 341 is slidably disposed in the blade groove 322. One end of the fastening part 342 is located in the blade groove 322 and connected to the side of the blade body 341 adjacent to the blade connector 340. The other end of the fastening part 342 is located in the receiving cavity 323, and the other end of the fastening part 342 extends into the threaded hole 352 of the blade connector 350 and is threadedly connected to the blade connector 350. When connecting the cutting blade 340 and the blade connector 350, the blade body 341 is placed in the blade groove 322 so that the fastening part 342 is located in the receiving cavity 323. Then, the blade connector 350 is placed into the receiving cavity 323. Then, the threaded hole 352 of the blade connector 350 is aligned with the fastening part 342. Then, the blade connector 350 is rotated so that the fastening part 342 enters the threaded hole 352 and connects with the blade connector 350. In this way, the connection between the blade connector 350 and the cutting blade 340 can be achieved without tools, which improves the convenience and efficiency of connecting the blade connector 350 and the cutting blade 340 in the receiving cavity 323.

[0046] It is understandable that because the waste material in the second exhaust channel 301 has a certain degree of hardness, the cutting blade 340 is prone to wear after cutting the waste material for a period of time. This makes it difficult for the cutting blade 340 to continue cutting the waste material in the second exhaust channel 301, ultimately rendering the cutting blade 340 unusable. To improve the service life of the cutting blade 340, such as... Figure 5As shown, in one embodiment, the die-casting mold 10 further includes an elastic connector 400, which is connected to the moving mold fixing member 210 and the second vent block 320 respectively, so that the second vent block 320 is loosely connected to the moving mold fixing member 210. In this embodiment, the elastic connector 400 is an elastic structure, that is, the elastic connector 400 can deform under force. The second vent block 320 is elastically connected to the moving mold fixing member 210 through the elastic connector 400, so that the second vent block 320 can be displaced under force. This allows the closing guide member 330 to be inserted into the closing guide hole 321 of the second vent block 320 to guide the second vent block 320, thereby making the first vent block 310 and the second vent block 320 face each other and form the second vent channel 301, avoiding the problem of blockage of the second vent channel 301. Furthermore, after the molten metal in the molding cavity 222 cools and solidifies, the core part 220 and the cavity part 120 separate, causing the first vent block 310 to separate from the second vent block 320. At this time, the elastic connector 400 immediately extends and pushes the second vent block 320 to separate from the moving mold fixing part 210, which accelerates the separation speed of the second vent block 320 from the moving mold fixing part 210. This reduces the time that the protruding part 370 abuts against the moving mold fixing part 210 when the first vent block 310 and the second vent block 320 separate, thereby reducing the time that the protruding part 370 hinders the elastic element 360 from pushing the blade connector 350 to rotate and slide. This increases the speed at which the elastic element 360 pushes the blade connector 350 to rotate and slide, thereby increasing the speed at which the cutting blade 340 slides toward the second vent channel 301, and thus increasing the cutting speed of the cutting blade 340. This improves the cutting effect of the cutting blade 340, allowing the cutting blade 340 to continue cutting even after wear, and increasing the service life of the cutting blade 340.

[0047] To allow the blade connector 350 to slide and rotate within the receiving cavity 323, such as Figure 5As shown, in one embodiment, the blade connector 350 has a waist-shaped hole 351 along its length. The exhaust assembly 300 also includes a mounting member 380, which is connected to the inner wall of the receiving cavity 323. The mounting member 380 passes through the waist-shaped hole 351, so that the blade connector 350 is rotatably connected to the mounting member 380, and simultaneously the blade connector 350 is slidably connected to the mounting member 380. This achieves the blade connector 350 being slidably and rotatably connected to the receiving cavity 323. Furthermore, since the blade connector 350 can move relative to the mounting member 380, the blade connector 350 can easily detach from the blade connector 350, thus preventing the blade connector 350 from pushing the cutting blade 340 to cut the waste. Therefore, in one embodiment, a limiting groove is formed in the wall of the waist-shaped hole 351. The limiting groove is arranged along the extending direction of the waist-shaped hole 351. A sliding part 381 protrudes from one end of the mounting member 380 adjacent to the waist-shaped hole 351. The sliding part 381 is confined within the limiting groove, thus avoiding the problem of the mounting member 380 detaching from the blade connector 350, thereby ensuring that the cutting blade 340 cuts the waste.

[0048] like Figure 5 As shown, in one embodiment, there is a gap between the telescopic hole 324 and the protruding member 370, so that the protruding member 370 has space to rotate and slide with the blade connector 350. Since the blade connector 350 has two movements, namely rotation and sliding, and the protruding member 370 is connected to the blade connector, causing the protruding member 370 to rotate and slide with the blade connector 350, in this embodiment, there is a gap between the telescopic hole 324 and the protruding member 370, so that the protruding member 370 has space to rotate and slide with the blade connector. This avoids the hole wall of the telescopic hole 324 from obstructing the movement of the blade connector 350, and thus avoids the hole wall of the telescopic hole 324 from obstructing the cutting movement of the cutting blade 340.

[0049] It is understood that the protrusion 370 is connected to the blade connector 350, and the blade connector 350 is slidably and rotatably connected within the receiving cavity 323. This makes it difficult for the protrusion 370 to enter the telescopic hole 324, and consequently, it makes it difficult for the protrusion 370 to extend through the telescopic hole 324 to the outside of the second exhaust block 320. This makes it easier for the protrusion 370 to continuously obstruct the elastic element 360 from pushing the blade connector 350, and consequently, it makes it easier for the cutting blade 340 to fail to cut the waste material in the second exhaust channel 301. Therefore, as Figure 5As shown, in one embodiment, the exhaust assembly 300 further includes a guide 390 connected to the receiving cavity 323. The guide 390 has a guide hole 391 communicating with the telescopic hole 324. The protruding member 370 is also located within the guide hole 391, so that the guide 390 guides the protruding member 370 to the telescopic hole 324, thereby preventing the protruding member 370 from deviating from the predetermined position. This ensures that the protruding member 370 extends through the telescopic hole 324 to the outside of the second exhaust block 320, and ensures that the elastic element 360 can be rotated by the blade connector 350, so that the cutting blade 340 enters the second exhaust channel 301 and cuts the waste in the second exhaust channel 301.

[0050] Furthermore, since the blade connector 350 is rotatably connected to the receiving cavity 323 and slidably connected to the receiving cavity 323, the protrusion 370 connected to the blade connector 350 also has rotation and sliding capabilities, meaning the protrusion 370 can rotate and translate. To prevent the protrusion 370 from getting stuck in the guide hole 391, such as... Figure 5 As shown, in one embodiment, there is a gap between the protrusion 370 and the wall of the guide hole 391, allowing the protrusion 370 to rotate and slide within the guide hole 391, thereby preventing the protrusion 370 from getting stuck in the guide hole 391, and ensuring that the protrusion 370 can extend to the outside of the second exhaust block 320 through the telescopic hole 324. The tab ensures that the cutting blade 340 cuts the waste in the second exhaust channel 301.

[0051] To prevent molten metal from entering the cutter groove 322, in one embodiment, the venting assembly 300 further includes a seal 410. The seal 410 is disposed within the cutter groove 322, and its opposite sides elastically abut against the cutting blade 340 and the groove wall of the cutter groove 322, respectively. This prevents molten metal from entering the cutter groove 322 and avoids the problem of the cutting blade 340 becoming stuck within it. In this embodiment, the seal 410 is an elastic structure. When the cutting blade 340 is fully retracted into the cutter groove 322, one side of the seal 410 elastically abuts against the groove wall of the cutter groove 322, and the other side of the seal 410 elastically abuts against the cutting blade 340. This seals the gap between the cutting blade 340 and the groove wall of the cutter groove 322, thereby suppressing molten metal from entering the gap between the cutting blade 340 and the groove wall of the cutter groove 322. Even if molten metal enters the gap between the cutting blade 340 and the groove wall of the groove 322, the cutting blade 340 pushes the seal 410 to contract when it slides into the second exhaust channel 301, thereby preventing the waste material entering the gap and the seal 410 from obstructing the cutting blade 340 from entering the second exhaust channel 301 to cut the waste material.

[0052] However, when the cutting blade 340 cuts the waste material in the second exhaust channel 301, the waste material in the second exhaust channel 301 is prone to bending and lifting, causing the surface of the waste material to tilt towards the cutting blade 340, thereby reducing the cutting effect of the cutting blade 340. Consequently, the waste material in the second exhaust channel 301 remains adhered to other waste material after being cut. To improve the cutting effect of the cutting blade 340, such as... Figure 6 As shown, in one embodiment, the cavity component 120 has a pressure hole 121, which is connected to the first exhaust channel 224. The die-casting mold 10 also includes a pressure assembly 500, which includes a pressure drive component 510 and a pressure component 520. Both the pressure drive component 510 and the pressure component 520 are disposed in the pressure hole 121. One end of the pressure component 520 is connected to the power output end of the pressure drive component 510, and the end face of the other end of the pressure component 520 is flush with the surface of the cavity component 120 before the core component 220 separates from the cavity component 120. When the core 220 separates from the cavity 120, the pressing drive 510 drives the pressing member 520 to continuously abut against the waste in the first exhaust channel 224. This causes the pressing member 520 to press down on the waste in the first exhaust channel 224 when the cutting blade 340 cuts the waste in the second exhaust channel 301, thereby suppressing the problem of the waste in the second exhaust channel 301 bending and lifting, thus improving the cutting effect of the cutting blade 340, so that the cutting blade 340 cuts the waste in the second exhaust channel 301, thereby reducing the maximum adhesion force of the waste, and thus improving the convenience of ejecting the die-cast product and waste. It can be understood that the pressing drive 510 can be a cylinder, a motor, or other existing linear drive components.

[0053] To prevent the molten metal from burning the pressure drive component 510, such as Figure 6 As shown, in one embodiment, the pressing assembly 500 further includes a heat insulation element that covers the pressing drive 510, suppressing the heat conduction of the molten metal to the pressing drive 510, thereby reducing the temperature of the pressing drive 510 and preventing the pressing drive 510 from burning out. In one embodiment, the heat insulation element is asbestos, fiberglass, rock wool, or other existing heat insulation elements.

[0054] Because the clamping element 520 is movably connected to the clamping hole 121, a gap can easily exist between the clamping element 520 and the wall of the clamping hole 121. This allows molten metal to easily enter the gap between the clamping element 520 and the clamping hole 121, resulting in waste material formed after the molten metal cools and hindering the movement of the clamping element 520. To avoid the above problems, such as... Figure 6As shown, in one embodiment, the cavity component 120 further includes a tapered hole 122, which communicates with the pressing hole 121 and is adjacent to the first exhaust channel 224. The pressing component 520 includes a pressing connecting portion 521 and a tapered pressing portion 522. The two ends of the pressing connecting portion 521 are respectively connected to the power output end of the pressing drive component 510 and the tapered pressing portion 522. The tapered pressing portion 522 is adapted to the tapered hole 122. The outer surface of the tapered pressing portion 522 abuts against the wall of the tapered hole 122 before the core component 220 separates from the cavity component 120, and the end face of the tapered pressing portion 522 facing away from the pressing hole 121 is flush with the surface of the cavity component 120. When the core 220 separates from the cavity 120, the pressing drive 510 drives the conical pressing part 522 to continuously abut against the waste material in the first exhaust channel 224. In this embodiment, before the core 220 separates from the cavity 120, the conical pressing part 522 abuts against the wall of the conical hole 122, increasing the contact area between the conical pressing part 522 and the cavity 120, thereby improving the sealing effect between the pressing part 520 and the cavity 120, thus preventing the molten metal from hindering the movement of the pressing part 520 after cooling, and ensuring that the pressing part 520 can press the waste material in the first exhaust channel 224.

[0055] like Figures 1 to 3 As shown, in one embodiment, the die-casting mold 10 further includes a core-pulling mechanism 600, which abuts against one side of the core 220 when the core 220 and the cavity 120 are closed. In this embodiment, the core-pulling mechanism 600 is used to form a hole on the side of the die-cast product. When the core 220 and the cavity 120 are closed, that is, when the core 220 and the cavity 120 form a sequentially connected feed channel 221, forming cavity 222, overflow cavity 223 and first venting channel 224, the core-pulling mechanism 600 abuts against one side of the core 220, so that the forming cavity 222 is a cavity with a hole, thereby forming a die-cast product with a hole in the forming cavity 222.

[0056] like Figure 2 and Figure 3As shown, in one embodiment, the core-pulling mechanism 600 includes an inclined guide post 610 and a sliding member 620. The first end of the inclined guide post 610 is fixedly connected to the fixed mold fixing member 110, and the inclined guide post 610 is inclined to the closing direction of the core member 220 and the cavity member 120. The sliding member 620 is slidably connected to the moving mold fixing member 210. The sliding member 620 has an inclined guide hole 621. The second end of the inclined guide post 610 is slidably inserted into the inclined guide hole 621, so that the core-pulling mechanism 600 abuts against one side of the core member 220 when the core member 220 and the cavity member 120 are closed. In this embodiment, one end of the inclined guide post 610 is fixedly connected to the fixed mold fixing member 110, and the other end of the inclined guide post 610 is movably inserted into the inclined guide hole 621. The distance between the inclined guide post 610 and the cavity member 120 is less than the distance between the inclined guide post 610 and the core member 220, so that the inclined guide post 610 is inclined in the closing direction of the core member 220 and the cavity member 120. When the core member 220 and the cavity member 120 are closed, the inclined guide post 610 is inserted into the inclined guide hole 621, so that the sliding member 620 slides in the direction of the core member 220 and is connected to the moving mold fixing member 210, so that the sliding member 620 abuts against the core member 220, thereby making the molding cavity 222 formed by the closure of the core member 220 and the cavity member 120 have a hole. When the core part 220 separates from the cavity part 120, the inclined guide post 610 extends out of the inclined guide hole 621, so that the sliding part 620 slides in the direction away from the core part 220 onto the moving mold fixing part 210, thereby separating the sliding part 620 from the core part 220, and further separating the sliding part 620 from the die-cast product, improving the convenience of removing the die-cast product.

[0057] It is understandable that after the core 220 separates from the cavity 120, the inclined guide post 610 and the inclined guide hole 621 are completely separated. However, the sliding member 620 has an inertia that moves away from the core 220, making it easy for the sliding member 620 to detach from the moving mold fixing member 210. Consequently, the sliding member 620 cannot abut against the core 220 after the core 220 and the cavity 120 close again, thus preventing the die-casting mold 10 from continuing normal die-casting. To improve the continuity of die-casting molding and increase the production efficiency of the die-casting mold 10, such as... Figure 3 As shown, in one embodiment, the core-pulling mechanism 600 further includes a limiting member 630, which is connected to one side of the moving mold fixing member 210 and is disposed opposite to the sliding member 620. After the inclined guide post 610 separates from the inclined guide hole 621, the limiting member 630 abuts against the sliding member 620 to prevent the sliding member 620 from disengaging from the moving mold fixing member 210, so that the sliding member 620 can continue to abut against the core member 220 after the core member 220 and the cavity member 120 close again.

[0058] like Figure 1 As shown, in one embodiment, the die-casting mold 10 further includes an ejector assembly 700. The ejector assembly 700 is connected to the side of the moving mold fixing member 210 opposite to the fixed mold fixing member 110. The ejector assembly 700 is used to eject the die-cast product. In this embodiment, the ejector rod of the ejector assembly 700 passes through the core member 220. After the molten metal in the forming cavity 222 cools and solidifies, the core member 220 separates from the cavity member 120. The ejector rod of the ejector assembly 700 ejects the die-cast product from the forming cavity 222, thereby removing the die-cast product.

[0059] This application also provides a battery box 20, which is obtained using the die-casting mold 10 described in any of the above embodiments. For example... Figures 1 to 4 As shown, the die-casting mold 10 further includes a fixed mold assembly 100, a moving mold assembly 200, and a venting assembly 300. The fixed mold assembly 100 includes a fixed mold fixing member 110 and a cavity member 120. The cavity member 120 is embedded in the fixed mold fixing member 110 so that the fixed mold fixing member 110 fixes the cavity member 120. The moving mold assembly 200 includes a moving mold fixing member 210 and a core member 220. The core member 220 is embedded in the moving mold fixing member 210 so that the moving mold fixing member 210 fixes the core member 220 and simultaneously causes the moving mold fixing member 210 to drive the core member 220 to move, so that the core member 220 closes and separates from the cavity member 120. The core component 220 and the cavity component 120 are closed to form a sequentially connected feeding channel 221, forming cavity 222, overflow cavity 223 and first exhaust channel 224. The molten metal, i.e., the molten metal, enters the forming cavity 222 through the feeding channel 221 and is formed. The molten metal that enters the forming cavity 222 first is cooled and formed in the overflow cavity 223. The air in the forming cavity 222 is exhausted through the first exhaust channel 224.

[0060] like Figures 2 to 4As shown, the venting assembly 300 further includes a first venting block 310, a second venting block 320, and a closing guide 330. The first venting block 310 is fixedly connected to the fixed mold fixing member 110 and is disposed adjacent to the cavity member 120. The second venting block 320 is loosely connected to the moving mold fixing member 210 and is disposed adjacent to the core member 220. The second venting block 320 has a closing guide hole 321. One end of the closing guide 330 is fixedly connected to the first venting block 310, and the other end of the closing guide 330 is movably inserted into the closing guide hole 321, so that the first venting block 310 and the first venting block 320 are closed to form a second venting channel 301 communicating with the first venting channel 224. The air in the molding cavity 222 is discharged to the outside of the die-casting mold 10 through the overflow cavity 223, the first venting channel 224, and the second venting channel 301 in sequence. In this embodiment, the second vent block 320 is loosely connected to the moving mold fixing member 210, that is, after the second vent block 320 is connected to the moving mold fixing member 210, it can still move relative to the moving mold fixing member 210 so that the closing guide member 330 can be inserted into the closing guide hole 321 and correct the second vent block 320, that is, so that the closing guide member 330 moves the second vent block 320 to the correct position.

[0061] The aforementioned battery box 20 is die-cast using die-casting mold 10. Because the second vent block 320 is loosely connected to the moving mold fixing member 210, its position is adjustable after installation. Since one end of the closing guide member 330 is fixedly connected to the first vent block 310, and the other end is movably inserted into the closing guide hole 321 of the second vent block 320, the closing guide member 330 adjusts, or guides, the position of the second vent block 320, ensuring correct alignment between the first vent block 310 and the second vent block 320 and forming the second vent channel 301. This avoids blockage of the second vent channel 301, preventing the formation of pores on the surface of the die-cast product and improving its appearance quality (i.e., improving surface flatness). Simultaneously, it prevents the formation of pores inside the die-cast product, thereby increasing its strength. Because the first vent block 310 and the second vent block 320 are correctly aligned, the fitting accuracy between the second vent block 320 and the moving mold fixing member 210 is improved, avoiding leakage of molten metal through the gap between the second vent block 320 and the moving mold fixing member 210. Furthermore, since the second vent block 320 can be aligned by inserting the closing guide member 330 into the closing guide hole 321 of the second vent block 320, the installation requirements of the second vent block 320 are reduced, thereby improving the installation efficiency of the second vent block 320.

[0062] This application also provides an LED light, including the aforementioned battery box.

[0063] Compared with the prior art, the present invention has at least the following advantages:

[0064] Because the second vent block 320 is loosely connected to the moving mold fixing member 210, its position is adjustable after installation. Since one end of the closing guide member 330 is fixedly connected to the first vent block 310, and the other end is movably inserted into the closing guide hole 321 of the second vent block 320, the closing guide member 330 adjusts, or guides, the position of the second vent block 320, ensuring correct alignment between the first vent block 310 and the second vent block 320 and forming the second vent channel 301. This avoids blockage of the second vent channel 301, preventing porosity on the surface of the die-cast product and improving its appearance quality (surface flatness). Simultaneously, it prevents internal porosity, thus increasing the product's strength. Correct alignment of the first vent block 310 and the second vent block 320 improves the fit accuracy between the second vent block 320 and the moving mold fixing member 210, preventing leakage of molten metal through the gap between them. Furthermore, since the second exhaust block 320 can be guided by the closed guide 330 inserted into the closed guide hole 321 of the second exhaust block 320, the installation requirements of the second exhaust block 320 are reduced, thereby improving the installation efficiency of the second exhaust block 320.

[0065] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
