[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] As shown in Figure 1 With Figure 3 , the present embodiment provides a technical solution: a metal mold capable of rapid heat dissipation, comprising: a compression mold assembly 1; the compression mold assembly 1 comprises a movable mold 11, and a top mold 12 is slidably connected to the outer side of the movable mold 11;

[0031] The movable mold 11 is the movable part of the mold, which is used to cooperate with the fixed mold to form a closed cavity. The top mold 12 is located on the outer side of the movable mold 11 and is connected with the movable mold 11 by sliding connection, which may be used for further molding or positioning;

[0032] As shown in Figure 1 - Figure 3 , a heat conduction assembly 2; the heat conduction assembly 2 comprises an outer frame 21, an inner frame 22 is fixedly connected inside the outer frame 21, and a fin 23 is fixedly connected inside the inner frame 22;

[0033] The outer frame 21 is the peripheral structure of the heat conduction assembly 2, which plays a role in fixing and protecting the internal structure. The inner frame 22 provides a support structure for the fin 23. The design of the inner frame 22 needs to consider the close cooperation with the outer frame 21 to ensure the stability of the entire assembly. The fin 23 is responsible for increasing the heat dissipation area and improving the heat exchange efficiency. The fin 23 is fixedly connected inside the inner frame 22 and is made of high thermal conductivity material;

[0034] Chamber assembly 3; Chamber assembly 3 includes a heat-conducting cavity 31 opened between the outer frame 21 and the inner frame 22, and a heat dissipation cavity 32 is provided between the inner frame 22 and the top mold 12;

[0035] like Figure 3 As shown, the heat conduction cavity 31 is the space between the outer frame 21 and the inner frame 22. The main function of this cavity is to provide a channel for heat conduction. The heat dissipation cavity 32 is the space between the inner frame 22 and the top mold 12. Its main function is to provide an additional heat dissipation area.

[0036] like Figure 1 and Figure 4 As shown, the cooling component 4 includes a circulating cooling water pipe 41 fixedly connected to the fins 23. One end of the circulating cooling water pipe 41 is fixedly connected to an inlet pipe 42, one end of an outlet pipe 43 is fixedly connected to the circulating cooling water pipe 41, and the other end of the outlet pipe 43 is fixedly connected to the bottom end of the outer frame 21.

[0037] The design of the circulating cooling water pipe 41 effectively transfers heat from the fins 23 to the cooling water pipe. The pipe material may be a metal with high thermal conductivity, such as copper or stainless steel, to ensure rapid heat transfer. The inlet pipe 42 is fixedly connected to one end of the circulating cooling water pipe 41, responsible for introducing cooling water into the piping system. One end of the outlet pipe 43 is fixedly connected to the circulating cooling water pipe 41, and the other end is fixedly connected to the bottom of the outer frame 21. This design allows the cooling water to carry away heat after flowing through the fins 23 and be discharged from the system through the outlet pipe 43. To reduce unit vibration and noise, when the chilled water piping route changes, a fixed support needs to be added 1000mm away from the point of change. When the chilled water piping is a straight section, a fixed support needs to be added every 2500mm.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, the circulation component 5 includes a water tank 51, a water pump 52 fixedly connected to the bottom of the water tank 51, a water pump 53 fixedly connected to the top of the water tank 51, the output end of the water pump 53 fixedly connected to the inlet pipe 42, the input end of the water pump 53 fixedly connected to the water tank 51, the output end of the water pump 52 fixedly connected to the water tank 51, the input end of the water pump 52 fixedly connected to the outlet pipe 43, and a condenser 54 fixedly connected inside the water tank 51.

[0039] Water tank 51 is used to store the cooling water required for circulation, water pump one 52 is designed to suck water into water tank 51, water pump two 53 is to send cooling water from water tank 51 into water pipe 42, and then into circulating cooling water pipe 41 to achieve the circulation of cooling water, condenser 54 is to reduce the temperature of the water in water tank 51, to ensure that the water used in circulation is kept within a range that can achieve cooling.

[0040] Working principle:

[0041] As shown in Figure 1 - Figure 4 As shown in

[0042] In use: when cooling is needed, first start the condenser 54 to cool the water in the water tank 51, and then start the water pump two 53 to send the cooling liquid to the circulating cooling water pipe 41 through the water inlet pipe 42, the connection of the circulating cooling water pipe 41 and the fin 23 offsets the heat emitted by the fin 23 to the heat dissipation cavity 32, thereby achieving the effect of cooling, secondly, when the water pump one 52 is started, the water flow will flow through the circulating cooling water pipe 41 to the water outlet pipe 43, and the water pump one 52 will send the liquid in the water outlet pipe 43 to the water tank 51, and then through the condenser 54 to cool, thereby realizing the effect of circulation, and in the process of heat dissipation, the heat is in the heat dissipation cavity 32, which is transmitted to the inside of the heat conduction cavity 31 through the fin 23, due to the connection of the circulating cooling water pipe 41 and the fin 23, the heat can be transmitted through the fin 23, and cooled and cooled through the effect of the circulating cooling water pipe 41, thereby achieving the purpose of cooling, secondly, when the fin 23 generates heat interaction, due to the temperature difference, water vapor will be generated in the inside of the heat conduction cavity 31, and the water vapor will accumulate in the inside of the heat conduction cavity 31, and then slide to the bottom end along the inside of the outer frame 21, at this time, when the water pump one 52 is started, the excess water vapor condensed by the water pump one 52 will be re-sent to the water tank 51 through the water pump one 52, so as to avoid the residue of the water flow.
