[0037] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0038] Example 1

[0039] like Figures 2-4 As shown, a conformal cooling water channel system for an injection mold includes an upper cooling component 3 arranged inside an upper mold 1 and a lower cooling component 4 arranged inside a lower mold 2; the upper cooling component 3 includes at least two groups of upper cooling main channels 31 arranged in an annular shape, and the lower cooling component 4 includes at least two groups of lower cooling main channels 41 arranged in an annular shape, and the upper cooling main channels 31 and the lower cooling main channels 41 are staggered with each other; auxiliary channels 5 are respectively arranged between multiple groups of upper cooling main channels 31 and lower cooling main channels 41, and the auxiliary channels 5 are composed of two groups of channel units arranged crosswise with each other.

[0040] Among them, by setting the upper cooling main channel 31 to cooperate with the auxiliary channel 5, and the lower cooling main channel 41 to cooperate with the auxiliary channel 5, a dual-channel conformal cooling water channel is realized. The upper cooling main channel 31 and the lower cooling main channel 41 are large-flow special-section channels, which fit the main contour of the mold and improve the overall cooling efficiency. The auxiliary channel 5 adopts a small-flow special-section branch structure to perform fine cooling on the areas not covered by the upper cooling main channel 31 and the lower cooling main channel 41 to meet local cooling needs.

[0041] By arranging the upper cooling main channel 31 and the lower cooling main channel 41 to be staggered with each other, since the fan blade product is relatively thin, the upper cooling main channel 31 and the lower cooling main channel 41 arranged on the upper and lower sides of the fan blade product and staggered with each other can achieve full coverage of the fan blade surface, thereby ensuring the uniformity of the fan blade cooling.

[0042] In the present embodiment, the upper cooling assembly 3 comprises two groups of upper cooling main channels 31 arranged in a ring shape, and the lower cooling assembly 4 comprises three groups of lower cooling main channels 41 arranged in a ring shape, the upper cooling main channels 31 and the lower cooling main channels 41 are arranged in an interleaved manner, which is particularly suitable for complex-shaped molds, such as fan blade molds, since fan blade products are usually thin and have complex shapes, the interleaved arrangement of the cooling main channels can ensure uniform cooling of the entire surface, thereby avoiding problems such as thermal stress concentration, warping or cracking caused by uneven cooling.

[0043] The sub-channels 5 mainly cover the areas that cannot be effectively cooled by the main channels through small-flow special-shaped cross-section branch structures, and the sub-channels 5 are composed of two groups of channel units arranged in an interleaved manner, which can ensure accurate cooling of the edges or complex-shaped parts of the mold during the entire cooling process, reduce temperature gradients, and avoid local overheating or uneven cooling.

[0044] The design of the upper cooling main channels 31 and the lower cooling main channels 41 not only provides large-flow cooling water flow channels that can quickly and effectively cool large areas, but also further improves the cooling effect through the supplementary cooling of the sub-channels 5. The detailed design of the sub-channels 5 can supplement the small areas that cannot be covered by the main channels, avoid cooling dead angles, and accurately cool local thin-walled or easily deformed areas, thereby improving product quality and mold service life.

[0045] The shape-following cooling technology adopted by the present application is designed according to the shape changes of the product, which can accurately adapt to the needs of molds of different shapes and minimize quality problems caused by uneven cooling. For complex-shaped molds, the shape-following cooling technology has great advantages and can achieve rapid and uniform cooling, greatly improving the precision and appearance quality of the product.

[0046] Through the interleaved design of the upper cooling main channels 31 and the lower cooling main channels 41 and the supplementary cooling of the sub-channels 5, the mold surface can be fully covered, especially for thin-walled products like fan blades, the cooling system can ensure that the temperature of each area is controlled within a reasonable range, effectively avoiding local overheating or uneven cooling, thereby improving the quality of injection molded products.

[0047] Further, as shown in Figures 2-4 The upper cooling main channels 31 and the lower cooling main channels 41 respectively comprise an upper channel portion 311 at the upper end, a lower channel portion 312 at the lower end, and a connecting channel portion 313 connecting the upper channel portion 311 and the lower channel portion 312, the lower channel portion 312 in the upper cooling main channels 31 is inclined, and the upper channel portion 311 in the lower cooling main channels 41 is inclined.

[0048] Wherein, by setting the upper channel part 311, the lower channel part 312 and the connecting channel part 313, the waterway of the upper cooling main channel 31 and the lower cooling main channel 41 is not a planar structure, and the cooling water not only flows along the upper cooling main channel 31 and the lower cooling main channel 41 in a circumferential direction, but also moves up and down along the upper channel part 311, the lower channel part 312 and the connecting channel part 313, thereby realizing multi-dimensional movement in the mold. The advantage of this arrangement is that, on the one hand, the cooling medium can flow smoothly in irregular spaces by bending, tilting, spiraling, S-shaped and other three-dimensional arrangements according to the structure of the mold; on the other hand, the connecting channel part 313 not only serves as a physical path, but also balances the pressure and temperature, so that the cooling water does not have a serious pressure loss or flow rate mutation when transferring between the upper channel part 311 and the lower channel part 312. A local expansion area or a turbulence structure can be provided to guide the cooling liquid to be more evenly distributed in the entire main channel system.

[0049] The entire upper cooling main channel 31 and the lower cooling main channel 41 form a continuous, continuous and conformal cooling circuit system through the above three structural subparts. This design avoids the generation of cooling dead angles, and the three-section channel structure enhances the flexibility and controllability of the waterway, which is suitable for various complex curved surface molds. The size and position of the upper and lower channel parts 312 can be customized and optimized according to the specific heating characteristics of the mold, thereby maximizing the local response capability of the cooling system.

[0050] Further, as shown in Figure 7 , the cross-sectional area of the upper cooling main channel 31 or the lower cooling main channel 41 is greater than the cross-sectional area of the channel unit.

[0051] The cross-sectional area of the upper cooling main channel 31 and the lower cooling main channel 41 is large, which can ensure the smooth flow of the cooling medium in the cooling system and is not prone to blockage or uneven flow.

[0052] The channel unit is a branch or a subdivided area of the cooling main channel, which is usually used to guide the cooling medium to a specific heat source position, and has a smaller cross-sectional area to achieve fine temperature control.

[0053] Example two

[0054] Wherein, the same or corresponding parts as in example one are denoted by corresponding reference numerals in example one, and for the sake of simplicity, only the difference from example one will be described below. The difference between example two and example one is that:

[0055] As shown in Figures 1-9 , the application also provides an injection mold, which comprises an upper mold 1 and a lower mold 2 that cooperate with each other;

[0056] The lower mold 2 is internally provided with a lower flow guide assembly 6 for forming a lower cooling main channel 41;

[0057] The upper mold 1 is internally provided with an upper flow guide assembly 7 for forming an upper cooling main channel 31.

[0058] The lower flow guide assembly 6 comprises a plurality of groups of annularly arranged lower flow guide blocks 61 and a plurality of groups of annularly arranged upper flow guide blocks 62, the lower flow guide blocks 61 and the upper flow guide blocks 62 are arranged alternately, and the lower flow guide blocks 61 and the upper flow guide blocks 62 are made of aluminum material.

[0059] Wherein, by arranging the upper flow guide blocks 62 and the lower flow guide blocks 61 in the injection mold, and the upper flow guide blocks 62 and the lower flow guide blocks 61 are made of aluminum material, which is a high thermal conductivity material, this arrangement can improve the cooling efficiency and ensure rapid heat conduction.

[0060] The upper flow guide blocks 62 and the lower flow guide blocks 61 adopt high-thermal-conductivity aluminum material, which can significantly improve the heat conduction efficiency. The thermal conductivity of aluminum material is excellent, which can accelerate the heat transfer of cooling water flow in the mold, so as to ensure that the mold can reach a stable working temperature in a short time, and reduce the damage of thermal stress to the mold.

[0061] The following gives a comparative example of the thermal conductivity, density, processing difficulty and the like of aluminum material and ordinary steel material, and the following comparative chart is given:

[0062] Material Thermal conductivity (W / m K) Density (g / cm³) Processing difficulty Aluminum (Al) 237 2.7 Easy to process, good thermal conductivity Ordinary steel 50 7.85 Rust-prone, relatively poor thermal conductivity

[0063] As can be clearly seen from the above, the upper flow guide blocks 62 and the lower flow guide blocks 61 made of aluminum material have the characteristics of being lighter and easier to process, while also having better thermal conductivity.

[0064] As shown in Figure 9 Each group of annularly arranged lower flow guide blocks 61 and each group of annularly arranged upper flow guide blocks 62 have the same fan blade height relative to the end of each group of lower flow guide blocks 61 or upper flow guide blocks 62, that is, the cross-sectional end height difference of the plurality of groups of lower flow guide blocks 61 or upper flow guide blocks 62 is the same as the fan blade inclination direction.

[0065] Further, as shown in Figure 5 The upper end of the lower flow guide block 61 is inclined, and the inclination angle is greater than 5°.

[0066] Wherein, the upper end of the lower flow guide block 61 is inclined, which can effectively improve the flow characteristics of the cooling liquid, and the inclination angle greater than 5° helps to reduce the friction between the cooling liquid and the surface of the flow guide block, thereby reducing the flow resistance and making the cooling liquid flow more smoothly;

[0067] The inclined design avoids the "dead angle" or stagnation of the cooling liquid in the channel, which enables the cooling liquid to cover the mold surface more uniformly, improves the cooling effect, especially in complex geometric molds, and avoids local overheating and uneven cooling;

[0068] In addition, when the cooling liquid passes through the inclined flow guide block, the flow speed and direction can be effectively guided, avoiding flow instability and promoting effective heat transfer.

[0069] An inclination angle greater than 5° is a reasonable design choice, which can ensure the stability of the cooling liquid flow and reduce the friction between the cooling liquid and the surface of the flow guide block. In addition, an excessive inclination angle may result in excessive cooling liquid flow rate, which cannot fully absorb the heat generated on the mold surface, while a smaller inclination angle may not effectively reduce the flow resistance. Preferably, the inclination angle is 5°-15°.

[0070] The specific inclination angle can also be adjusted according to the specific size of the mold, cooling requirements, and different needs of the injection molding process. For example, for large molds, a smaller inclination angle may be needed to avoid excessive cooling liquid flow rate; for small precision molds, a larger inclination angle can be considered to speed up the cooling process.

[0071] It should be noted that since the lower channel portion 312 in the upper cooling main channel 31 is inclined, the upper channel portion 311 in the lower cooling main channel 41 is inclined, and therefore the lower end of the upper flow guide block 62 in the upper flow guide assembly 7 is inclined, and the inclination angle is the same as the inclination angle of the upper end of the lower flow guide block 61 in the lower flow guide assembly 6. Since the structure of the upper flow guide assembly 7 and the lower flow guide assembly 6 is basically the same, the difference is only that the orientations of the upper flow guide block 62 and the lower flow guide block 61 in the two assemblies are opposite, therefore, the specific structure of the upper flow guide assembly 7 will not be described again.

[0072] Further, as shown in Figure 7 The lower mold 2 is further provided with a first water inlet pipe 8 connected to one end of the lower cooling main channel 41 and a first water outlet pipe 9 connected to the other end of the lower cooling main channel 41.

[0073] The lower mold 2 is further provided with a second water inlet pipe 10 and a second water outlet pipe 11 connected to both ends of the auxiliary channel 5, respectively.

[0074] The first water inlet pipe 8 is used to introduce cooling liquid into the mold, ensuring that the flow and flow rate of the cooling liquid can meet the cooling requirements. It is connected to one end of the lower cooling main channel 41, and after the cooling liquid enters the lower cooling main channel 41 through this pipe, it begins to effectively conduct and cool the heat of the mold.

[0075] After flowing through the lower cooling main channel 41, the coolant takes away the heat inside the mold and is discharged from the mold through the first outlet pipe 9. This outlet controls the outflow speed and flow rate of the coolant, thereby adjusting the circulation efficiency of the coolant in the mold.

[0076] The second water inlet pipe 10 is used to introduce the coolant into the auxiliary channel 5 for supplementary cooling with the lower cooling main channel 41. Through the design of the auxiliary channel 5, the coolant can effectively enter the specific area of ​​the mold, solving the problem of some parts of the mold that are difficult to cool;

[0077] The second water outlet pipe 11 is used to discharge the cooling liquid in the secondary channel 5 after cooling, ensuring that the cooling liquid in the cooling system can flow smoothly and maintain good circulation with the cooling system outside the mold.

[0078] The configuration of the first water inlet pipe 8, the first water outlet pipe 9, the second water inlet pipe 10 and the second water outlet pipe 11 enables the lower cooling main channel 41 and the secondary channel 5 to work together efficiently, ensuring smooth flow of the coolant and enhancing the cooling effect of the mold.

[0079] Further, if Figure 8 As shown, several groups of heat-conducting rods 12 are further provided inside the lower mold 2 , one end of the heat-conducting rod 12 extends into the interior of the secondary channel 5 , and the other end passes through the lower guide block 61 and extends to the outside of the lower mold 2 .

[0080] Among them, by arranging multiple groups of heat-conducting rods 12 inside the injection mold, the heat-conducting rods 12 are connected between the auxiliary channel 5 and the upper cooling main channel 31 or the lower cooling main channel 41. This arrangement can speed up the discharge of heat between the auxiliary channel 5 and the upper cooling main channel 31 or the lower cooling main channel 41, thereby ensuring that the conformal cooling water channel system has a good cooling effect.

[0081] In detail, the heat-conducting rod 12 is connected between the auxiliary channel 5 and the upper cooling main channel 31 or the lower cooling main channel 41. This design enables the heat-conducting rod 12 to form a heat transfer bridge between the auxiliary channel 5 and the cooling main channel, providing an additional heat transfer path between the auxiliary channel 5 and the cooling main channel, which can effectively accelerate the heat discharge during the cooling process. The heat-conducting rod 12 enhances the heat exchange effect, making the overall heat discharge of the cooling water channel system more efficient, ensuring that the temperature inside the mold can be quickly balanced, thereby improving the cooling effect. The heat-conducting rod 12 usually uses a metal material with high thermal conductivity (such as copper, aluminum, etc.) to efficiently transfer heat.

[0082] Through the reasonable layout of the heat-conducting rods 12, the cooling water channel system can be made more efficient. This design can improve the overall performance of the cooling system and ensure that the cooling process will not be affected by regional heat accumulation, thereby improving production efficiency, reducing mold loss, and improving the precision and surface quality of injection molded products.

[0083] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that modifications can be made to the technical solutions described in the foregoing embodiments, or some of the technical features thereof can be replaced by equivalent features. Any modifications, equivalent replacements, improvements, and the like made within the spirit and principle of the present application should be included in the protection scope of the present application.
