[0025] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present application.

[0026] Embodiment one: please refer to Figures 1-6 The present application provides the following technical scheme: an injection mold easy to dissipate heat, comprising a mold main body 1, a mold base 2 fixedly installed at the bottom of the mold main body 1, a mold core 3 provided on the outer wall of the mold main body 1, a water cooling heat dissipation mechanism provided on the outer wall of the mold core 3 for water cooling and heat dissipation of the mold core 3, the water cooling heat dissipation mechanism comprising a heat conduction pipe 302 fixedly installed on the outer wall of the mold core 3, and a heat dissipation fin 301 fixedly installed on the outer wall of the heat conduction pipe 302 and connected with the outer wall of the mold core 3, a cooling chamber 4 provided inside the mold main body 1, a water storage tank 5 fixedly installed on the outer wall of the mold main body 1, a circulating pump 402 fixedly installed on the top of the water storage tank 5, a cooling pipe 401 and a connecting pipe 403 fixedly installed on the end of the circulating pump 402, a water inlet pipe 501 and a return pipe 404 fixedly installed on the outer wall of the water storage tank 5, cooling liquid provided inside the water storage tank 5, the heat conduction pipe 302 corresponding to the outer wall of the mold core 3, a plurality of groups of heat conduction pipes 302 provided at equal intervals on the outer wall of the mold core 3, the heat conduction pipes 302 being made of copper pipe material, a plurality of groups of heat dissipation fins 301 provided at equal intervals on the outer wall of the heat conduction copper pipe, each group of heat dissipation fins 301 being connected with a plurality of groups of heat conduction pipes 302, the heat dissipation fins 301 being made of copper sheet material, the cooling chamber 4 being located between the mold core 3 and the mold main body 1, the cooling chamber 4 corresponding to the mold core 3, the mold core 3 and the mold main body 1 being sealed, one end of the cooling pipe 401 being in communication with the inside of the cooling chamber 4, the other end of the cooling pipe 401 being connected with the end of the circulating pump 402, one end of the connecting pipe 403 being in communication with the inside of the water storage tank 5, the other end of the connecting pipe 403 being connected with the end of the circulating pump 402, one end of the return pipe 404 being in communication with the inside of the cooling chamber 4, and the other end of the return pipe 404 being in communication with the inside of the water storage tank 5.

[0027] When the injection molding machine injects high-temperature molten plastic into the cavity composed of the mold core 3 and the mold body 1, the temperature of the mold rises sharply, at which time the water-cooled heat dissipation mechanism is quickly put into operation. Since the mold core 3 is tightly installed with a plurality of groups of heat pipes 302 distributed at equal intervals on the outer wall, and these heat pipes 302 are made of copper material with high thermal conductivity, the large amount of heat absorbed by the mold core 3 can be quickly transferred to the heat pipes 302. At the same time, the heat dissipation fins 301 fixed on the outer wall of the heat pipes 302 greatly expand the heat dissipation area, so that the heat can be more efficiently diffused to the surrounding environment. Under the power drive of the circulating pump 402, the cooling liquid in the water storage tank 5 flows into the circulating pump 402 through the connecting pipe 403, and then is pumped into the cooling pipe 401, and then enters the cooling chamber 4. The cooling liquid flows in the cooling chamber 4 and fully contacts with the heat pipes 302 and the heat dissipation fins 301, absorbs a large amount of heat conducted by them, and the temperature rises. Then, the cooling liquid that has absorbed heat flows back to the water storage tank 5 through the return pipe 404, completing a cycle of heat dissipation process. Such circulation and repetition continuously take out the heat of the mold core 3, thereby effectively reducing the temperature of the mold core 3, creating favorable conditions for rapid cooling of the injection molding product.

One end of the cold air flow channel 601 is in communication with a cold air chamber 602, and the other end of the cold air flow channel 601 is in communication with the heat dissipation fan 6. The cold air chamber 602 is located between the cooling chamber 4 and the outer wall of the mold body 1, and the cross section of the cold air chamber 602 is designed in a U shape.

One end of the heat dissipation hole 603 is in communication with the cold air chamber 602, and the other end of the heat dissipation hole 603 penetrates through the outer wall of the mold body 1.
