It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0018] See also Figures 1 to 3The water channel of the precision mold of the embodiment of the utility model includes a rotating shaft device 1, a first straight tube 2, a second straight tube 3, a first annular tube 4 and a second annular tube 5. The rotating shaft device 1 is arranged through the mold core and the template, the first annular tube 4 is arranged in an annular manner on the upper half of the rotating shaft device 1, and the second annular tube 5 is arranged in an annular manner on the lower half of the rotating shaft device 1. One end of the first annular tube 4 is connected with one end of the second annular tube. The first straight tube 2 and the second straight tube 3 are arranged on the template. The first straight tube 2 is connected with the first annular tube 4, and the second straight tube 3 is connected with the second annular tube 5.

[0019] In the above embodiment, the rotating shaft device 1 is a key part of the mold and is arranged between the mold core and the template. Its main function is to ensure that the mold core can move smoothly during the mold closing and opening process to complete the injection molding and demoulding operations. Since the rotating shaft device 1 is in direct contact with the high-temperature mold core during operation, its temperature will also rise rapidly. In order to avoid performance degradation and damage caused by high temperature, it needs to be effectively cooled. In order to achieve this goal, the first annular tube 4 and the second annular tube 5 are respectively arranged in the upper and lower parts of the rotating shaft device 1. The two annular tubes surround the rotating shaft device 1 in an annular shape to form a complete cooling circuit. One end of the first annular tube 4 is connected to one end of the second annular tube 5 to form a closed circulating water circuit. This design not only ensures that the cooling water can be evenly distributed around the rotating shaft device 1, but also greatly simplifies the design of the water system. The first straight tube 2 and the second straight tube 3 are arranged on the template as the inlet and outlet of the cooling water. Through these two straight tubes, the cooling water can smoothly enter and flow out of the mold. When the mold is working, the cooling water enters the mold from the first straight tube 2, first flows through the first annular tube 4, and cools the upper part of the rotating shaft device 1; then, the cooling water flows into the second annular tube 5, and cools the lower part of the rotating shaft device 1; finally, the cooling water flows out of the mold through the second straight tube 3, completing a complete cooling cycle. The advantage of this design is that it makes full use of the space inside the mold, and closely integrates the cooling water circuit with the rotating shaft device 1 and the mold core. In this way, when the cooling water flows in the annular tube, it can not only reduce the temperature of the mold core, but also cool the rotating shaft device 1 at the same time. This double cooling effect greatly improves the heat dissipation efficiency of the mold and ensures that the mold can work stably in a high temperature environment.

[0020] See also Figures 1 to 3 In another embodiment, the cross-sections of the first straight tube 2 and the second straight tube 3 are circular.

[0021] In the above embodiment, the cross-sections of the first straight tube 2 and the second straight tube 3 are both circular. This design not only simplifies the structure of the water system, but also optimizes the flow efficiency of the cooling water. The circular cross-section makes the cooling water encounter less resistance when flowing in the pipe, thereby improving the smoothness of the water flow and the cooling efficiency. At the same time, the design of the circular pipe also enhances the structural strength of the water system, making it more able to withstand the high pressure and high temperature environment during the operation of the mold. When the cooling water enters the mold from the first straight tube 2, flows through the annular tube to cool the rotating shaft device 1 and the mold core, and then flows out from the second straight tube 3, the circular cross-section design ensures the continuity and stability of the entire cooling process.

[0022] See also Figures 1 to 3 In another embodiment, the cross-sections of the first annular tube 4 and the second annular tube 5 are elliptical.

[0023] In the above embodiment, the elliptical cross section can provide a larger surface area under the same circumference compared to the traditional circular design, which means that the contact area between the cooling water and the pipe wall is larger, thereby enhancing the heat exchange efficiency and making the cooling effect more significant. At the same time, the elliptical design can reduce the use of materials to a certain extent while maintaining the structural strength, thereby achieving a lightweight design. When the cooling water flows through these annular tubes with elliptical cross sections, it can not only effectively reduce the temperature of the mold core, but also fully cool the rotating shaft device 1 that passes through the mold core and the template, ensuring that it can still work stably in a high temperature environment.

[0024] See also Figures 1 to 3 In another embodiment, the water pipe sections of the first annular tube 4 and the second annular tube 5 surrounding the rotating shaft device 1 are at the same distance from the surface of the rotating shaft device 1 .

[0025] In the above embodiment, the core advantage of this equidistant design is that it ensures that the cooling water can evenly and effectively cover the entire surface of the shaft device 1 when flowing through the annular pipe. Since the water pipe section is at the same distance from the surface of the shaft device 1, the pressure and flow rate of the cooling water at each point can be kept consistent, avoiding the problem of local overheating or insufficient cooling. This evenly distributed cooling effect can not only significantly improve the heat dissipation efficiency of the shaft device 1 and extend its service life, but also ensure that the mold still maintains stable performance in a high-temperature working environment.

[0026] See also Figures 1 to 3 In another embodiment, the parallel distance between the first straight tube 2 and the second straight tube 3 is 3 cm.

[0027] In the above embodiment, the constant parallel distance ensures that the flow state of the fluid in the two pipes can remain consistent, thereby avoiding uneven flow rate or pressure fluctuation caused by distance changes. Secondly, the 3 cm spacing is a choice based on engineering practice and fluid dynamics principles. It can not only ensure the physical independence of the two pipes, but also ensure easy maintenance and replacement when necessary. In addition, this design also improves the overall stability of the pipeline system and reduces the potential risks caused by mutual interference between pipes.

[0028] See also Figures 1 to 3 In another embodiment, the upper and lower distance between the first straight tube 2 and the second straight tube 3 is 6 cm.

[0029] In the above embodiment, the 6 cm upper and lower distance ensures that there is enough space between the first straight tube 2 and the second straight tube 3, which is convenient for installation, maintenance and replacement. At the same time, this distance also avoids the reduction of heat exchange efficiency and possible interference problems caused by the pipes being too close. More importantly, the 6 cm upper and lower distance design also helps to achieve a more uniform cooling effect. When the cooling water enters and flows out of the mold through these two straight tubes, the appropriate spacing can ensure that the cooling water forms a more stable flow inside the mold, thereby more effectively reducing the mold temperature and improving the service life and molding quality of the mold.

[0030] See also Figures 1 to 3 In another embodiment, the first straight tube 2, the second straight tube 3, the first annular tube 4 and the second annular tube 5 are all manufactured by integral molding.

[0031] In the above embodiment, integrated molding manufacturing means that these pipes are directly formed in a single processing process, rather than being assembled from multiple parts. This manufacturing method greatly reduces the connection points and potential leakage risks between pipes, and improves the overall reliability of the system. At the same time, integrated molding manufacturing also ensures the fluidity and smoothness of the inside of the pipe, reduces water flow resistance, and improves cooling efficiency. Cooling water can flow quickly and evenly in these pipes, effectively reducing the temperature of the mold and the rotating shaft device 1. In addition, integrated molding manufacturing also makes the entire water system more compact and lightweight, which is convenient for layout and installation inside the mold. This not only saves space, but also reduces the overall weight of the mold and improves production efficiency.

[0032] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
