[0027] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the following will describe the detailed implementation manners of the present utility model in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Such as Figures 1-4As shown, the first embodiment: A insert cooling structure and a die-casting mold are provided. The insert cooling structure includes an insert assembly 1 and a cooling structure 2 for cooling the insert assembly 1. The insert assembly 1 includes a first insert 101, and the first insert 101 is provided with a first positioning portion 1011 and a second positioning portion 1012 extending upward. The cooling structure 2 includes a first cooling water channel 201 formed according to the shapes of the first insert 101, the first positioning portion 1011, and the second positioning portion 1012.

[0029] Specifically, by arranging the first cooling water channel 201, the coolant can flow through the key parts of the first positioning portion 1011 and the second positioning portion 1012 of the first insert 101 more efficiently, ensuring that heat is dissipated rapidly, better maintaining the thermal balance state of the mold, shortening the molding cycle of the product, and improving production efficiency.

[0030] When the coolant flows into the first cooling water channel 201, the liquid flows through the first insert 101, the first positioning portion 1011, and the second positioning portion 1012, taking away the excess heat, thereby achieving efficient cooling.

[0031] Furthermore, as Figure 1 and Figure 2 shown, the first positioning portion 1011 and the second positioning portion 1012 are arranged at intervals on the first insert 101; a support portion 3 is provided between the first positioning portion 1011 and the second positioning portion 1012.

[0032] Specifically, the setting of the support portion 3 provides additional support, reduces the deformation during workpiece heat treatment, and improves the service life of the insert.

[0033] Furthermore, as Figure 3 and Figure 4 shown, the first cooling water channel 201 includes a first cooling section 2011, a second cooling section 2012, and a first connection section 2015. The first cooling section 2011, the second cooling section 2012, and the first connection section 2015 are in an N shape and are arranged corresponding to the shape of the first positioning portion 1011. The first connection section 2015 is close to the top edge of the first positioning portion 1011.

[0034] Specifically, by designing the first cooling water channel 201 as an N-shaped structure including the first cooling section 2011, the second cooling section 2012, and the first connection section 2015, the cooling effect can be further optimized, the thermal balance performance of the mold can be improved, and the molding cycle can be shortened.

[0035] Furthermore, as Figure 3 and Figure 4As shown, the first cooling water channel 201 further includes a third cooling section 2013, a fourth cooling section 2014, and a second connecting section 2016. The third cooling section 2013, the fourth cooling section 2014, and the second connecting section 2016 are arranged corresponding to the shape of the second positioning portion 1012, and the second connecting section 2016 is close to the top edge of the second positioning portion 1012. The first cooling water channel 201 further includes a connecting pipe 2017, and the connecting pipe 2017 is arranged between the second cooling section 2012 and the third cooling section 2013.

[0036] Specifically, the coolant flows into the first cooling section 2011, flows through the first connecting section 2015 to the second cooling section 2012, and through the connecting pipe 2017, the coolant flows from the second cooling section 2012 to the third cooling section 2013, and then flows through the second connecting section 2016 to the fourth cooling section 2014, ensuring that the coolant can efficiently cover the entire surfaces of the first positioning portion 1011 and the second positioning portion 1012, and guaranteeing that heat is quickly and evenly carried away.

[0037] Furthermore, as Figure 3 and Figure 4 shown, the first cooling water channel 201 further includes a first water inlet pipe 2018 and a first water outlet pipe 2019. The first water inlet pipe 2018 is connected to the first cooling section 2011, and the first water outlet pipe 2019 is connected to the fourth cooling section 2014.

[0038] Specifically, the coolant flows into from the first water inlet pipe 2018, is preliminarily cooled through the first cooling section 2011, the coolant flows through the first connecting section 2015 to the second cooling section 2012 for further cooling, through the connecting pipe 2017, the coolant flows from the second cooling section 2012 to the third cooling section 2013, and then flows through the second connecting section 2016 to the fourth cooling section 2014 to complete the final cooling process, and finally the coolant flows out through the first water outlet pipe 2019.

[0039] A die-casting mold includes a fixed mold and a movable mold, and the above-mentioned insert cooling structure is provided on the fixed mold or the movable mold.

[0040] Specifically, by providing the insert cooling structure on the fixed mold or the movable mold, the overall cooling efficiency and thermal balance performance of the mold are further improved, the molding cycle of the product is shortened, and the production efficiency and product quality are improved.

[0041] The second embodiment, as Figures 5-8 shown, the present insert cooling structure and die-casting mold are different from the first embodiment in that: the insert assembly 1 further includes a second insert 102, and the second insert 102 is provided with a third positioning portion 1021 extending upward, and the cooling structure 2 includes a second cooling water channel 202 for cooling the second insert 102.

[0042] Specifically, the second cooling water channel 202 is arranged according to the shapes of the second insert 102 and the third positioning portion 1021. Through the second cooling water channel 202, the coolant can flow through the second insert 102 and the third positioning portion 1021 more efficiently, ensuring rapid heat dissipation, better maintaining the thermal balance state of the mold, shortening the molding cycle of the product, and improving production efficiency.

[0043] Furthermore, as Figure 7 and Figure 8 shown, the top end of the third positioning portion 1021 is conical. The second cooling water channel 202 includes a fifth cooling section 2021 arranged corresponding to the top end shape of the third positioning portion 1021, and the end of the fifth cooling section 2021 is N-shaped.

[0044] Specifically, by designing the top end of the third positioning portion 1021 as conical and adding a fifth cooling section 2021 corresponding to the shape of the third positioning portion 1021 in the second cooling water channel 202, the coolant can cover and cool the key area more efficiently.

[0045] Furthermore, as Figure 7 and Figure 8 shown, the second cooling water channel 202 further includes a second water inlet pipe 2022 and a second water outlet pipe 2023, and the second water inlet pipe 2022 and the second water outlet pipe 2023 are connected to the fifth cooling section 2021 in a circulating manner.

[0046] Specifically, the coolant flows in from the second water inlet pipe 2022, passes through the N-shaped path of the fifth cooling section 2021 to ensure that the coolant can evenly cover and cool the conical top end of the third positioning portion 1021. After the coolant efficiently cools the third positioning portion 1021, it flows out from the second water outlet pipe 2023, forming a complete cooling circulation system.

[0047] Furthermore, as Figure 8 shown, the radial dimensions of the second water inlet pipe 2022 and the second water outlet pipe 2023 are larger than the radial dimension of the fifth cooling section 2021.

[0048] Specifically, by increasing the radial dimensions of the second water inlet pipe 2022 and the second water outlet pipe 2023, the coolant can flow into and out of the fifth cooling section 2021 with a higher flow rate and lower resistance, thereby improving the cooling efficiency and overall thermal balance performance.
