DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0024] like Figures 1 to 4 As shown, the die-casting mold cooling assembly of the embodiment of the utility model includes a first cooling line 100 and a second cooling line 200. The first cooling line 100 is suitable for surrounding the outer side of the mold, and the first cooling line 100 has a plurality of first cooling sections 1 arranged in a bend and connected to each other. The second cooling line 200 is connected to the first cooling line 100, and the second cooling line 200 is suitable for surrounding the inner side of the mold, and the second cooling line 200 has a plurality of second cooling sections 2 arranged in a bend and connected to each other.

[0025] Specifically, Figure 1 As shown, the first cooling pipeline 100 and the second cooling pipeline 200 are interconnected, and the first cooling pipeline 100 and the second cooling pipeline 200 are arranged at intervals in the radial direction of the mold, and the first cooling pipeline 100 surrounds the outer side of the mold, and the second cooling pipeline 200 surrounds the inner side of the mold.

[0026] The first cooling pipeline 100 has a plurality of first cooling sections 1 that are interconnected and arranged in a bent manner. The second cooling pipeline 200 has a plurality of second cooling sections 2 that are interconnected and arranged in a bent manner.

[0027] The die-casting mold cooling assembly of the embodiment of the utility model can extend the length of the cooling water circuit, increase the cooling area, and improve the cooling efficiency by providing a first cooling segment 1 with a bent arrangement on the first cooling pipeline 100 and a second cooling segment 2 with a bent arrangement on the second cooling pipeline 200. In addition, since the first cooling segment 1 and the second cooling segment 2 are bent, they can fit more closely with the outer surface of the mold, thereby ensuring the balance of cooling of the mold by the cooling water circuit, thereby improving the cooling uniformity of the die-casting mold.

[0028] By increasing the cooling area and improving the fit between the cooling pipe and the outer surface of the mold, the mold can be cooled quickly, the internal heat of the product can be quickly transferred out, and the internal shrinkage problem of the product can be improved.

[0029] In some embodiments, a first angle A is formed between two adjacent first cooling sections 1, and 40°≤A≤50°.

[0030] Specifically, Figure 2 As shown, there is a first angle A between the axes of two adjacent first cooling sections 1, and A may be 40°, 42°, 45°, 48°, 49° or 50°.

[0031] For example, when the first angle A is 45°, the cooling area formed by the first cooling pipeline 100 is increased by 1.5 times compared to the cooling area formed by the straight water channel in the related art.

[0032] It should be noted that when the first angle is too large, the spacing distance between two adjacent first cooling sections 1 increases, resulting in a decrease in the length of the entire first cooling pipeline 100, resulting in a decrease in the cooling area, affecting the cooling efficiency. Conversely, when the first angle is too small, the spacing distance between two adjacent first cooling sections 1 decreases, resulting in the first cooling pipeline 100 being bent too many times, which is prone to stress concentration and will also increase the volume of the first cooling pipeline 100, resulting in an increase in occupied space, which is not conducive to combining the insert with the mold.

[0033] In some embodiments, a second angle B is provided between two adjacent second cooling sections 2, and 60°≤B≤72°.

[0034] Specifically, Figure 3 As shown, there is a second angle B between the axes of two adjacent second cooling sections 2, and A can be 60°, 62°, 64°, 66°, 70° or 72°.

[0035] For example, when the first angle is 66°, the cooling area formed by the second cooling pipe is doubled compared to the cooling area formed by the straight water channel.

[0036] It should be noted that when the second angle is too large, the spacing distance between two adjacent second cooling sections 2 increases, resulting in a decrease in the length of the entire second cooling pipeline 200, resulting in a decrease in the cooling area, affecting the cooling efficiency. Conversely, when the second angle is too small, the spacing distance between two adjacent second cooling sections 2 decreases, resulting in the second cooling pipeline 200 being bent too many times, which is prone to stress concentration and will also increase the volume of the second cooling pipeline 200, resulting in an increase in occupied space, which is not conducive to the combination of the insert and the mold.

[0037] In some embodiments, the first cooling pipeline 100 has a water inlet 3, and the second cooling pipeline 200 has a water return port 4. The water inlet 3 and the water return port 4 are located on the same side of the mold. The water inlet 3 and the water return port 4 are arranged on the same side to facilitate the connection of the cooling pipeline with the external cooling pipe.

[0038] In some embodiments, multiple first cooling sections 1 are divided into a first cooling group 5 and a second cooling group 6, and the first cooling group 5 and the second cooling group 6 are arranged at intervals in the circumferential direction of the mold. The first cooling pipeline 100 has a first connecting section 7 and a second connecting section 8, one end of the first connecting section 7 is connected to the water inlet 3, the other end of the first connecting section 7 is connected to one end of the first cooling group 5, the other end of the first cooling group 5 is connected to one end of the second cooling group 6, and one end of the second connecting section 8 is connected to the other end of the second cooling group 6.

[0039] Specifically, Figure 1 As shown, the first cooling group 5 and the second cooling group 6 are symmetrically arranged in the front-to-back direction, the first cooling group 5 and the second cooling group 6 are located outside the outer surface of the mold, the first connecting section 7 and the second connecting section 8 are located above the mold, and the first connecting section 7 and the second connecting section 8 are both annular pipelines.

[0040] It should be noted that the cooling medium enters the first connecting section 7 through the water inlet 3 , then enters the first cooling group 5 and the second cooling group 6 through the first connecting section 7 , and then the cooling medium is discharged into the second connecting section 8 through the second cooling group 6 .

[0041] The multiple second cooling sections 2 are divided into a third cooling group 9 and a fourth cooling group 10, and the third cooling group 9 and the fourth cooling group 10 are arranged at intervals in the circumferential direction of the mold. The second cooling pipeline 200 has a third connecting section 11 and a fourth connecting section 12. One end of the third connecting section 11 is connected to an end of the second connecting section 8 away from the second cooling group 6, and the other end of the third connecting section 11 is connected to one end of the third cooling group 9, and the other end of the third cooling group 9 is connected to the fourth cooling group 10. One end of the fourth connecting section 12 is connected to the other end of the fourth cooling group 10, and the other end of the fourth connecting section 12 is connected to the return water port 4.

[0042] Specifically, Figure 1 As shown, the third cooling group 9 and the fourth cooling group 10 are arranged symmetrically in the front-to-back direction, the third cooling group 9 and the fourth cooling group 10 are located on the inner side of the mold, the third connecting section 11 and the fourth connecting section 12 are located above the mold, and the third connecting section 11 and the fourth connecting section 12 are both annular pipelines.

[0043] It should be noted that the cooling medium enters the third connecting section 11 through the second connecting section 8 , then enters the third cooling group 9 and the fourth cooling group 10 , and finally enters the fourth connecting section 12 after being cooled, and is discharged through the water return port 4 .

[0044] That is, the inlet of the first connecting section 7 is connected to the water inlet 3, the outlet of the first connecting section 7 is connected to the inlet of the first cooling group 5, the outlet of the first cooling group 5 is connected to the inlet of the second cooling group 6, the outlet of the second cooling group 6 is connected to the inlet of the second connecting section 8, the outlet of the second connecting section 8 is connected to the inlet of the third connecting section 11, the outlet of the third connecting section 11 is connected to the inlet of the third cooling group 9, the outlet of the third cooling group 9 is connected to the inlet of the fourth cooling group 10, the outlet of the fourth cooling group 10 is connected to the inlet of the fourth connecting section 12, and the outlet of the fourth connecting section 12 is connected to the return water port 4.

[0045] In some embodiments, the inner diameter of the first cooling line 100 and the inner diameter of the second cooling line 200 are both C, and 3 mm ≤ C ≤ 5 mm.

[0046] The first cooling pipeline 100 and the second cooling pipeline 200 have the same inner diameter to ensure that the flow rates of the two cooling pipelines are the same. For example, the inner diameter may be 3 mm, 4 mm, 4.5 mm, or 5 mm.

[0047] It should be noted that when the inner diameter is too small, the flow rate is reduced, which is not conducive to cooling the mold. Conversely, when the inner diameter is too large, although the flow rate increases, the diameter of the entire cooling pipeline increases, resulting in an increase in the space occupied by the cooling pipeline, which is not conducive to the combination of the insert and the mold.

[0048] In some embodiments, the distance between the outer surface of the first cooling pipeline 100 and the outer surface of the mold is L1, the distance between the outer surface of the second cooling pipeline 200 and the outer surface of the mold is L2, and L1=L2. When L1 is equal to L2, the distance between the cooling channel in the first cooling pipeline 100 and the cooling channel in the second cooling pipeline 200 and the mold is the same, which can further improve the uniformity of cooling the mold and ensure the balance of the mold surface temperature.

[0049] In some embodiments, the length of the first cooling pipeline 100 is the same as the length of the second cooling pipeline 200 , which can ensure that the pressure drops of the first cooling pipeline 100 and the second cooling pipeline 200 are the same.

[0050] Optionally, the length of the first cooling pipeline 100 and the length of the second cooling pipeline 200 are L3, and 150 mm ≤ L3 ≤ 250 mm.

[0051] For example, L3 can be 150 mm, 180 mm, 200 mm, 220 mm, or 250 mm. It should be noted that when L3 is too short, the cooling effect is poor. On the contrary, when L3 is too long, the size of the entire insert is too large, which is not conducive to combining with the mold.

[0052] In some embodiments, the first cooling pipeline 100 and the second cooling pipeline 200 are an integrated structure. For example, the first cooling pipeline 100 and the second cooling pipeline 200 can be integrally formed by 3D printing, thereby improving the manufacturing accuracy and structural strength of the cooling pipeline.
