[0028] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0029] like Figure 1 , 2 As shown, a water-cooling heat dissipation structure 1 of a mold insert comprises an insert 1, a heat exchange cavity 10 is opened in the insert 1, a heat exchange element 2 is arranged in the heat exchange cavity 10, and the heat exchange element 2 is arranged in the heat exchange cavity 10, and the heat exchange element 2 is clearance-matched with the insert 1;

[0030] The heat exchange element 2 is provided with a cooling channel 3, and the cooling channel 3 includes an end surface cooling channel 31 and a side surface cooling channel 32 which are not connected to each other. The end surface cooling channel 31 is provided on an end surface of the heat exchange element 2 facing the inside of the heat exchange cavity 10, and the side surface cooling channel 32 is provided around the side surface of the heat exchange element 2;

[0031] The end surface cooling channel 31 and the side surface cooling channel 32 are respectively connected to a cooling water source (not shown in the figure).

[0032] In this embodiment, the whole insert 1 structure in the prior art is split into a structure composed of the insert 1 and the heat exchanger 2, and the end surface cooling channel 31 and the side surface cooling channel 32 which are not connected to each other are respectively arranged on the end surface and the side surface of the heat exchanger 2, so that the cooling water directly contacts the inner wall of the insert 1, thereby greatly improving the heat exchange and cooling efficiency;

[0033] In addition, according to the cooling requirements of the side and end faces of the heat exchange chamber 10, the flow rate and / or temperature of the cooling water in the end face cooling channel 31 and the side face cooling channel 32 can be controlled separately, so as to achieve stable and controllable cooling.

[0034] Further, such as Figure 1 , 2 As shown, the end face cooling channel 31 includes an end face cooling flow channel 311, and the end face cooling flow channel 311 is provided with an end face water inlet hole 312 and an end face water outlet hole 313. The other ends of the end face water inlet hole 312 and the end face water outlet hole 313 extend through the interior of the heat exchanger 2 to the outer end face of the heat exchanger 2, and the end face water inlet hole 312 is connected to the cooling water source.

[0035] Further, such as Figure 1 , 2 As shown, the side cooling channel 32 includes a first side cooling channel 321 and a second side cooling channel 322 which are not connected to each other, and the first side cooling channel 321 and the second side cooling channel 322 are respectively connected to a cooling water source.

[0036] In this embodiment, an independently controlled double-side cooling channel 32 structure is adopted. Compared with the prior art, the cooling water flow resistance is small, and the cooling water flow rate and temperature can be adjusted and controlled according to the cooling requirements, which is suitable for more application scenarios.

[0037] Further, such as Figure 1 , 2 As shown, the first side cooling channel 321 includes a first side cooling channel 3211, and the first side cooling channel 3211 is provided with a first water inlet hole 3212 and a first water outlet hole 3213, and the other ends of the first water inlet hole 3212 and the first water outlet hole 3213 extend through the interior of the heat exchange element 2 to the outer end surface of the heat exchange element 2;

[0039] The first water inlet hole 3212 and the second water inlet hole 3222 are in communication with a cooling water source.

[0040] In this embodiment, the cooling water source absorbs the heat from the circumferential side walls and end faces of the heat exchange chamber 10 through the first side cooling channel 3211, the second side cooling channel 3221 and the end face cooling channel 311 respectively, and adopts a multi-faceted independent cooling control method, which is stable and controllable with high cooling efficiency.

[0042] In this embodiment, the above structure can increase the heat exchange area between the end surface cooling channel 311 and the heat exchange cavity 10, thereby improving the cooling effect on the end surface of the insert 1.

[0043] Furthermore, the first side cooling channel 3211 and the second side cooling channel 3221 are cylindrical spiral shapes.

[0044] In this embodiment, the above structure can increase the heat exchange area between the side cooling channel and the heat exchange cavity 10 , thereby improving the cooling effect on the circumferential side of the insert 1 .

[0045] Further, such as Figure 1 , 2 As shown, the first side cooling channel 3211 and the second side cooling channel 3221 are spirally wound.

[0046] In this embodiment, compared with a single side cooling channel structure with relatively dense distribution, the above structure has less resistance to the flow of cooling water, and the cooling process is controllable and efficient.

[0047] Furthermore, the gap between the heat exchange component 2 and the insert 1 is 0.02-0.03 mm on one side.

[0048] Furthermore, the mouth of the insert 1 is sealedly connected to the connection point of the heat exchange element 2.

[0051] In this embodiment, a large number of concave and convex shapes can be produced on the surface through sand surface anodizing, which greatly increases the surface area and improves the cooling and heat exchange effect.

[0052] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the utility model patent.
