[0024] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model in conjunction with the drawings. Many specific details are set forth in the following description in order 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.

[0025] As Figures 1 - 4 shown, a cosmetic cap mold insert and its mold are provided. The cosmetic cap mold insert includes an insert 1 for forming a cosmetic cap. A cooling channel 2 for cooling the formed cosmetic cap is provided inside the insert 1. The cooling channel 2 includes a first cooling pipeline 201 and a second cooling pipeline 202 that are connected and arranged in communication with each other.

[0026] Specifically, a cooling channel 2 is provided inside the insert 1. The cooling channel 2 can quickly take away the heat of the formed product, thereby significantly shortening the molding cycle, enabling multiple products to be produced in one mold, and improving production efficiency. The design of the double cooling pipelines ensures that the cooling medium can be evenly distributed inside the insert 1, avoiding local overheating or uneven cooling, and ensuring the quality and dimensional accuracy of the formed cosmetic cap.

[0027] Furthermore, the insert 1 includes a molding portion 101, and the first cooling pipeline 201 and the second cooling pipeline 202 are spirally and circuitously arranged along the height direction of the molding portion 101.

[0028] Specifically, the cooling pipelines arranged spirally and circuitously can cover the entire height of the molding portion 101 more evenly, ensuring that the cooling medium can fully absorb heat and avoiding local overheating or insufficient cooling; moreover, the arrangement of the spiral pipelines increases the flow path of the cooling medium, extends the cooling time, and further improves the cooling efficiency.

[0029] Furthermore, the cooling channel 2 further includes an input pipeline 203 and an output pipeline 204. The first cooling pipeline 201 and the second cooling pipeline 202 are located between the input pipeline 203 and the output pipeline 204. The input pipeline 203, the output pipeline 204, the first cooling pipeline 201 and the second cooling pipeline 202 are connected and arranged to form a circulating cooling water path.

[0030] Specifically, the cooling medium spirally and circuitously passes through the first cooling pipeline 201 and the second cooling pipeline 202 along the input pipeline 203, gradually absorbs the heat of the molding portion 101, and the heat-absorbed cooling medium is discharged from the mold through the output pipeline 204, taking away the heat.

[0031] Furthermore, a shunt branch 205 is provided on the input pipeline 203, and the input ends of the first cooling pipeline 201 and the second cooling pipeline 202 are connected to the shunt branch 205.

[0032] Specifically, through the shunt branch 205, the cooling medium can enter multiple cooling pipelines simultaneously, increasing the cooling path, improving the overall cooling efficiency, and ensuring the uniform distribution of the cooling medium in the mold, further avoiding problems such as local overheating or uneven cooling.

[0033] Furthermore, a confluence branch 206 is provided on the output pipeline 204, and the output ends of the first cooling pipeline 201 and the second cooling pipeline 202 are connected to the confluence branch 206.

[0034] Specifically, the confluence branch 206 ensures that the cooling medium can quickly converge and be discharged from the mold after absorbing heat in the first cooling pipeline 201 and the second cooling pipeline 202, forming an efficient circulating system.

[0035] Furthermore, the first cooling pipeline 201 includes a first input flow channel 2011 and a first output flow channel 2012. The first input flow channel 2011 is arranged in an upward spiral, and the first output flow channel 2012 is arranged in a downward spiral. A first connecting pipe 2013 which is communicatively connected is provided between the first input flow channel 2011 and the first output flow channel 2012. Cooling water flows into the first input flow channel 2011 and flows out of the first output flow channel 2012 through the first connecting pipe 2013.

[0036] Furthermore, the second cooling pipeline 202 includes a second input flow channel 2021 and a second output flow channel 2022. The second input flow channel 2021 is arranged in an upward spiral, and the second output flow channel 2022 is arranged in a downward spiral. A second connecting pipe 2023 which is communicatively connected is provided between the second input flow channel 2021 and the second output flow channel 2022. Cooling water flows into the second input flow channel 2021 and flows out of the second output flow channel 2022 through the second connecting pipe 2023.

[0037] Specifically, the cooling water enters the first input flow channel 2011 of the first cooling pipeline 201 and the second input flow channel 2021 of the second cooling pipeline 202 through the input pipeline 203 and the shunt branch 205. The cooling water spirally rises upward along the first input flow channel 2011 and the second input flow channel 2021 respectively, gradually absorbing the heat of the molding part 101. The cooling water flows into the first output flow channel 2012 and the second output flow channel 2022 through the first connecting pipe 2013 and the second connecting pipe 2023 respectively. The cooling water spirally descends downward along the first output flow channel 2012 and the second output flow channel 2022 respectively, continuing to absorb heat. The cooling water after heat absorption converges into the output pipeline 204 through the confluence branch 206, forming a unified discharge path. The cooling water is discharged from the mold through the output pipeline 204, taking away the heat.

[0038] Furthermore, the first cooling pipeline 201 and the second cooling pipeline 202 are flat.

[0039] Specifically, the flat cooling pipeline increases the contact area between the cooling water and the mold surface, improves the heat conduction efficiency, and accelerates the cooling process of the mold. The flat design makes the cooling pipeline more compact, occupies less internal space of the mold, is beneficial to optimizing the overall structure and design of the mold, and reduces the flow resistance of the cooling water, increases the flow rate of the cooling water, and further improves the cooling efficiency.
