[0023] In the process of cooling the injection mold, the water cooling component is used to utilize the heat transfer of water on the mold body 101 to take away the heat inside the mold body 101, thereby achieving the purpose of cooling. In the process of water cooling, the scale inhibitor is dropped into the transported cooling water through the inhibition component, and the scale inhibitor effectively prevents the formation of scale in the water cooling pipe 202, thereby ensuring the effect of heat conduction and further ensuring the efficiency of cooling.

[0024] The suppression component includes a storage box 401 installed at the upper end of the installation pipe 3, a scale inhibitor is placed inside the storage box 401, a cover plate 402 is hinged at the upper end of the storage box 401, and a discharge component for assisting the discharge is arranged inside the storage box 401 and the installation pipe 3; the discharge component includes an operation box 501 fixed at the lower end of the storage box 401, the operation box 501 is located inside the installation pipe 3, a rotating groove 502 is opened on the operation box 501, and the rotating groove 502 is communicated with the interior of the storage box 401 and the installation pipe 3 respectively, and the interior of the rotating groove 502 is connected to the storage box 401 and the interior of the installation pipe 3. The feeding barrel 503 is rotatably connected to the feeding barrel 503 which is matched with the feeding barrel 503, and a plurality of storage grooves 504 are provided on the feeding barrel 503. The feeding barrel 503 is driven to rotate by the rotating assembly. During the rotation of the feeding barrel 503, when the storage grooves 504 on the feeding barrel 503 are located inside the storage box 401, the scale inhibitor inside the storage box 401 falls into the storage grooves 504. When the storage grooves 504 on the feeding barrel 503 are located inside the mounting pipe 3, the scale inhibitor inside the storage grooves 504 falls into the transported cooling water.
