Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with a water cooling structure. Background Art

[0002] An injection mold is a tool used to produce plastic products and to give them a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and molten plastic into the mold cavity under high pressure through an injection molding machine, and then cooling and solidifying it to obtain a molded product.

[0003] An existing injection mold with a water-cooling structure (Announcement No.: CN219028270U) has at least the following disadvantages: although the device facilitates the disassembly of the injection mold, the water flow is stored inside the lower mold. While cooling the upper mold, it also causes the water flow temperature inside the lower mold to gradually increase, resulting in a slowdown in the mold cooling rate, which is not conducive to water cooling of the injection mold. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The water that absorbs heat is discharged into the water tank through the outlet pipe. The staff starts several cooling fans on the top of the water tank. The cooling fans blow air to cool the water. The water tank is open to facilitate the heat dissipation of hot water. The hot water and cold water are separated by a short partition. When there is a large amount of hot water in the hot water area, it will overflow the short partition and enter the cold water area, thereby achieving water circulation, which is beneficial to water cooling of the injection mold.

[0014] 2. After the cooling is completed, the staff will insert the water injection pipe and the water outlet pipe into the side pipe grooves on both sides of the upper mold respectively. The baffle will close one side of the side pipe groove to limit the water injection pipe and the water outlet pipe, which is convenient for the storage and use of the water injection pipe and the water outlet pipe. When in use, the staff will press the water injection pipe in the opposite direction to push the water injection pipe to move the water injection pipe out of the measuring pipe groove, making it convenient for the staff to pull out the water injection pipe and the water outlet pipe for use.
