[0002] In the current field of injection molding technology, injection molds are tools for producing plastic products; they are also tools that give plastic products a complete structure and precise dimensions. The main production method is to inject high-temperature molten plastic into the mold through high pressure and mechanical drive.

[0003] The utility model patent with the publication number CN214395298U discloses a mold cooling device for an injection molding machine, comprising an upper support, a lower support is arranged below the upper support, a sliding rod is arranged between the lower support and the upper support, an upper mold is installed on the lower end surface of the upper support, a lower mold is arranged below the upper mold, an upper mold cooling plate is installed inside the upper mold, a lower mold cooling plate is arranged outside the lower mold, cooling pipes are installed inside the lower mold cooling plate and the upper mold cooling plate, cooling water conduction blocks are arranged at the upper and lower ends of the inner side of the upper mold cooling plate, a movable frame is arranged at the lower end of the cooling water conduction block, and a sealing member is installed on one side of the movable frame. A pressure plate and a through-port are arranged on the lower side of the movable frame, and limit clamps are arranged on both sides of the outside of the lower mold cooling plate. The limit clamps are inserted into the movable frame and sealed with the through-port. One end of the sealed pressure plate extends to the inside of the cooling water conduction block and is slidably connected with the cooling water conduction block. A pressure spring is installed on one side of the cooling water conduction block, and a water outlet is arranged on one side of the cooling water conduction block.
