Description

Technical Field

[0001] This application relates to the technical field of die-casting molds, and in particular to a nozzle sleeve and cooling water jacket with a water-carrying structure. Background Technology

[0002] In die-casting molds, the sprue bushing, as a crucial component connecting the die-casting machine's pressure chamber and the mold cavity, directly impacts casting quality and mold lifespan through its cooling performance. Traditional sprue bushings typically lack a cooling system, relying on natural heat dissipation, which is insufficient to meet process requirements. This design flaw leads to severe thermal stress accumulation at the sprue bushing, easily causing quality issues such as cracking and molten metal bursting. Furthermore, it poses a significant safety hazard—if the sprue area is not fully solidified, the high-pressure molten metal inside may break through the solidified layer, causing an explosion. To avoid this risk, the mold opening time needs to be extended, reducing production efficiency and increasing production costs.

[0003] To address the aforementioned issues, patent CN206839110U proposes an integral die-casting mold sprue bushing. By incorporating multiple annular cooling channels at the direct-sprue section of the sprue bushing, cooling efficiency is significantly improved. However, this design lacks cooling channels in the thickest and slowest-cooling area of ​​the sprue at the connection between the nozzle and the bushing, resulting in insufficient heat dissipation in this critical area. In actual production, this uncooled, thick area becomes a heat accumulation zone, affecting not only the overall cooling uniformity but also potentially causing localized mold cracking or even bursting due to overheating, thus limiting further improvements in mold performance.

[0021] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1 to 4 The nozzle sleeve 10 with a water-carrying structure, as described in one embodiment of the present invention, includes a nozzle sleeve body 100 and a cooling channel 200. The nozzle sleeve body 100 has a thickened portion 110 on the side facing the mold flow channel, and a guide port 120 is opened in the middle of the thickened portion 110, which communicates with the flow channel. The nozzle sleeve body 100 has a water inlet hole 101 and a water outlet hole 102 on the side facing away from the flow channel. The cooling channel 200 is located inside the nozzle body 100. The cooling channel 200 includes a main cooling channel 210, a water inlet channel 220, and a water outlet channel 230. The main cooling channel 210 is located below the guide port 120. The two ends of the main cooling channel 210 are connected to the water inlet channel 220 and the water outlet channel 230, respectively. One end of the water inlet channel 220 is connected to one end of the main cooling channel 210, and the other end of the water inlet channel 220 is connected to the water inlet pipe of the mold (not shown) through the water inlet hole 101. One end of the water outlet channel 230 is connected to one end of the main cooling channel 210, and the other end of the water outlet channel 230 is connected to the water outlet pipe of the mold (not shown) through the water outlet hole 102.

[0022] In this embodiment, the aforementioned nozzle sleeve 10 with a water-cooling structure has a thickened portion 110 on the side with the guide port 120, so that the interior of the nozzle sleeve body 100 has sufficient space to accommodate the cooling channel 200. Furthermore, the nozzle sleeve 10 with a water-cooling structure, through the cooling channel 200 located in the nozzle area, improves the cooling efficiency of the nozzle area, accelerates the cooling and solidification of the nozzle area, shortens the mold opening waiting time, and improves production efficiency. Simultaneously, the cooling channel 200 avoids localized overheating caused by heat accumulation, reduces the risk of localized mold cracking or explosion, prevents aluminum molten metal splashing accidents during mold opening, and ensures safe and reliable production.

[0023] like Figures 1 to 4 As shown, in one embodiment, the main cooling channel 210 includes a first channel 211, a second channel 212 and a third channel 213. The first channel 211 is located below the guide port 120. The two ends of the first channel 211 are connected to the second channel 212 and the third channel 213, respectively. The end of the second channel 212 away from the first channel 211 is connected to the water inlet channel 220, and the end of the third channel 213 away from the first channel 211 is connected to the water outlet channel 230.

[0024] like Figure 1 and Figure 2 As shown, in one embodiment, a first machining hole 1101 is formed on the surface of the thickened portion 110, and a second machining hole 1102 and a third machining hole 1103 are formed at both ends of the thickened portion 110, respectively. Please refer to [link to relevant documentation]. Figure 4 The first channel 211 extends to the first machining hole 1101, the second channel 212 extends to the second machining hole 1102, and the third channel 213 extends to the third machining hole 1103. The first machining hole 1101, the second machining hole 1102, and the third machining hole 1103 are all provided with a first sealing element (not shown in the figure).

[0025] In this embodiment, the main cooling channel 210 is divided into three straight channels. The first channel 211 runs horizontally below the guide port 120. The second channel 212 and the third channel 213 extend from the second machining holes 1102 and the third machining holes 1103 on both sides of the thickened portion 110 towards the first channel 211 and are connected. It can be understood that when manufacturing the nozzle sleeve 10 with the water-carrying structure, a solid whole is manufactured first, and then the cooling channel 200 is machined by straight drilling, which simplifies the manufacturing process and reduces the manufacturing difficulty. At the same time, the straight pipes can ensure a stable cooling water flow rate. Furthermore, the first machining holes 1101, the second machining holes 1102, and the third machining holes 1103 used to machine the straight channels can be used to explore and clear the corresponding straight channels, avoiding a decrease in cooling efficiency due to channel blockage and damage.

[0026] Specifically, in this embodiment, the first sealing element is a tapered plug, which seals the machining hole to prevent cooling water from overflowing through the machining hole.

[0027] like Figure 1 and Figure 2 As shown, in one embodiment, the nozzle sleeve 10 with a water-carrying structure further includes a positioning flange 300. The positioning flange 300 is located on the side of the nozzle sleeve body 100 away from the guide port 120, and is arranged along the periphery of the nozzle sleeve body 100. It is understood that the positioning flange 300 assists in installation and positioning, ensuring that the guide port 120 faces the flow channel, avoiding misalignment that reduces cooling effect and overflow. Simultaneously, the positioning flange 300 also prevents the nozzle sleeve 10 with the water-carrying structure from shifting during use.

[0028] like Figures 1 to 3 As shown, in one embodiment, the water inlet 101 and the water outlet 102 are located on the positioning flange 300, the water inlet channel 220 is connected to the main cooling channel 210 through the first connecting channel 221, and the water outlet channel 230 is connected to the main cooling channel 210 through the second connecting channel 231.

[0029] like Figure 1 and Figure 3 As shown, in one embodiment, the bottom of the positioning flange 300 is provided with a fourth machining hole 301 and a fifth machining hole 302. The end of the first connecting channel 221 away from the main cooling channel 210 extends to the fourth machining hole 301, and the end of the second connecting channel 222 away from the main cooling channel 210 extends to the fifth machining hole 302. Both the fourth machining hole 301 and the fifth machining hole 302 are provided with a second sealing element (not shown in the figure).

[0030] In this embodiment, the inlet and outlet pipes are located on the positioning flange 300, and a first connecting channel 221 and a second connecting channel 231 are provided to communicate with the main cooling channel 210. The cooling water channels are arranged to adapt to the shape of the nozzle sleeve 10 with a water-carrying structure, thereby expanding the cooling range and improving cooling efficiency. At the same time, the positioning flange 300 is located above the guide port 120. The placement of the inlet and outlet pipes on the flange can make full use of gravity-assisted circulation and facilitate the connection between the inlet and outlet water channels 230 and the inlet and outlet water pipes of the mold.

[0031] Furthermore, the first connecting channel 221, the second connecting channel 231, the water inlet channel 220, and the water outlet channel 230 are all straight channels. When manufacturing the nozzle sleeve 10 with the water-carrying structure, they are formed by straight machining through the fourth machining hole 301, the fifth machining hole 302, the water inlet hole 101, and the water outlet hole 102, respectively, simplifying the machining process and reducing processing difficulty. Simultaneously, the corresponding straight channels are checked and cleared through each machining hole to ensure cooling efficiency.

[0032] Specifically, in this embodiment, the second sealing element is a tapered plug, the first connecting channel 221 and the second connecting channel 231 are vertical pipes, which are simple to process, and the fourth processing hole 301 and the fifth processing hole 302 at the end are both equipped with tapered plugs to seal water and prevent cooling water leakage.

[0033] Please see Figures 5 to 6 A cooling water jacket 20 includes a material sleeve 21 and a nozzle sleeve 10 with a water-carrying structure as described in any of the above embodiments. One end of the material sleeve 21 abuts against the nozzle sleeve 10 with the water-carrying structure. The material sleeve 21 is provided with a cooling water channel 22, an inlet pipe 23, and an outlet pipe 24. The cooling water channel 22 is located at the end of the material sleeve 21 near the nozzle sleeve 10 with the water-carrying structure, and the cooling water channel 22 communicates with the inlet pipe 23 and the outlet pipe 24. In this embodiment, through the cooperation of the material sleeve 21 and the nozzle sleeve 10 with the water-carrying structure, cooling of both the nozzle and the handle is achieved simultaneously, improving cooling efficiency, shortening the mold opening waiting time, and increasing production efficiency. This further ensures safe and reliable production.

[0034] like Figure 6 As shown, in one embodiment, the cooling water channel 22 includes multiple straight pipes 22a, which are connected in sequence and arranged along the inner wall of the material sleeve 21. Specifically, in this embodiment, there are three cooling water channels 22, which are located at different heights. Each cooling water channel 22 includes multiple straight pipes 22a, which extend from the inner side of the mold in multiple directions and are connected in sequence, forming a loop with the inlet and outlet water pipes 24. This ensures the cooling effect and simplifies the processing of the nozzle.

[0035] Compared with the prior art, this application has at least the following advantages: The aforementioned nozzle sleeve with a water-carrying structure has a thickened portion on one side where a guide port is provided, so that the inside of the nozzle sleeve body has sufficient space to accommodate a cooling channel.

[0036] The nozzle sleeve with a water-cooling structure improves the cooling efficiency of the nozzle area through the cooling channels set in the nozzle area, accelerates the cooling and solidification of the nozzle area, shortens the mold opening waiting time, and improves production efficiency.

[0037] By using cooling channels, localized overheating caused by heat accumulation is avoided, reducing the risk of local mold cracking or explosion, preventing aluminum molten metal splashing accidents during mold opening, and ensuring safe and reliable production.

[0038] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
