[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example 1

[0032] See also Figure 1-4 The utility model provides a technical solution: an injection mold for rapidly cooling and dissipating heat after molding an injection molded part, comprising:

[0033] The male mold plate 1 is provided with a mold core mounting groove 11, and the male mold plate 1 is provided with a cooling medium inlet flow channel 12 and a cooling medium outlet flow channel 13;

[0034] The male mold core 2 is provided with a cooling channel 21 inside, the inlet of the cooling channel 21 is connected to the cooling medium inlet channel 12, and the outlet of the cooling channel 21 is connected to the cooling medium outlet channel 13;

[0035] The auxiliary heat dissipation component 3 includes a driving member 31 and a fan 32. The fan 32 is slidably connected to the male mold plate 1. The fan 32 faces the male mold core 2. The driving member 31 is used to drive the fan 32 to slide along a straight line.

[0036] The driving member 31 is an electric push rod, which can precisely adjust the position of the fan 32 to improve the cooling and heat dissipation effect.

[0037] The two auxiliary heat dissipation components 3 are arranged on opposite sides of the male mold plate 1 , and the driving members 31 of the two auxiliary heat dissipation components 3 are arranged symmetrically, so that the two fans 32 are arranged opposite to each other, thereby ensuring uniform cooling and heat dissipation of the injection molded part.

[0038] The male mold plate 1 is provided with a slide rail 14, and a slider 15 is provided on the slide rail 14. The fan 32 is fixedly mounted on the connecting seat 321, and the connecting seat 321 is fixedly mounted on the slider 15. The driving member 31 drives the connecting seat 321 to slide smoothly along the slide rail 14.

[0039] The connecting seat 321 is provided with a rotating cylinder 4, and the fan 32 is fixedly mounted on the output end of the rotating cylinder 4. The fan 32 can be rotated to adjust the blowing angle on the basis of moving and adjusting the position, so as to further improve the cooling and heat dissipation effect.

[0040] The cross section of the slide rail 14 is trapezoidal to prevent the slide block 15 from falling off.

[0041] Working principle: After the injection molding, the male mold and the female mold are separated, and the injection molding remains on the male mold. Before the material is discharged through the ejector plate, the cooling channel 21 and the auxiliary heat dissipation component 3 cooperate to effectively realize the rapid cooling and heat dissipation of the mold and the injection molding, and avoid deformation of the injection molding during the material discharge process. Specifically, one end of the cooling medium inlet channel 12 extends to the bottom surface of the mold core mounting groove 11, and one end of the cooling medium discharge channel 13 extends to the bottom surface of the mold core mounting groove 11. The cooling medium (such as cooling oil) enters the cooling channel 21 of the male mold core 2 through the cooling medium inlet channel 12, and the cooling medium is discharged from the cooling channel 21 through the cooling medium discharge channel 13, effectively realizing the cooling of the male mold plate 1 and the male mold core 2, and realizing the cooling of the inner side of the injection molding; at the same time, the fans 32 on both sides of the male mold core 2 blow air toward the male mold core 2, and can adjust the position through the driving member 31 to realize the heat dissipation of the outer side of the injection molding. The combination of the two can effectively realize the rapid cooling and heat dissipation of the injection molding after molding.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
