[0029] It should be noted that the present invention is a rapid injection molding structure of an automobile part injection mold. When in use, the gate threaded sleeve 4 allows the gate of the injection mold to be replaced between the limiting ring 3 and the gate threaded sleeve 4, and can be adjusted and replaced according to the flow rate of the plastic, thereby adjusting the injection molding efficiency. After the gate threaded sleeve 4 is installed, the limiting ring 3 presses the translation adjustment plate 1 to fix it to the injection mold. After the injection mold is installed on the injection molding machine, the pin pile 102 between the translation adjustment plate 1 and the heat dissipation frame 2 prevents the rectangular bottom plate 101 from rotating.

The cooling liquid is poured into the interior of the hollow circular ring 207 and sprayed out through the nozzle 208. The cooling liquid mist is blown to the surface of the injection mold. As the cooling liquid on the surface of the injection mold evaporates, the heat of the injection mold is taken away, thereby accelerating the molding and hardening of the automobile parts. When adjusting the blowing direction of the cooling fan 206, the fan outer frame 205 in the rectangular outer frame 202 is rotated, and the fan outer frame 205 is turned over. The sponge strip 203 makes the rubber strip 204 fit the surface of the fan outer frame 205. The rubber strip 204 plays an anti-slip role. The strip groove on the surface of the rubber strip 204 plays a role in increasing friction. The translation adjustment plate 1 and the heat dissipation frame 2 can accelerate the heat dissipation of the injection mold, and can accelerate the molding and hardening of the automobile parts in the injection mold, thereby improving the injection efficiency of the injection mold. The translation adjustment plate 1 can adjust the distance between the heat dissipation frame 2 and the injection mold. The heat dissipation frame 2 can spray water mist to the surface of the injection mold, and blow air to the surface of the injection mold to dissipate heat, and the blowing direction can be turned over and adjusted.
