Problems solved by technology
[0002] In the process of plastic injection molding, the cooling section takes the most time in a molding cycle, and the hot nozzle needs to be cooled directly to improve the molding production efficiency; the cooling water jacket currently used is roughly a hollow cylindrical water jacket, and the water jacket is placed on the hot nozzle. On-mouth cooling of hot nozzles, see figure 1 As shown, there is a water tank 3 on the outside of the water jacket body 1, and the cooling water flows in the water tank 3 without directionality, which is prone to stagnant water, and the cooling effect is not ideal. Moreover, the water tank 3 is far away from the rubber port 2, and the cooling effect on the hot nozzle is not good.

The invention discloses a circulating cooling water jacket comprising a water jacket body, the head of the water jacket body is provided with a glue outlet; the water jacket body is internally provided with a cooling waterway which is close to the glue outlet, the cooling waterway is distributed around the glue outlet, and the outlet side of the water jacket body is provided with a water inlet and a water outlet which are communicated with the cooling waterway. By the way, the circulating cooling water jacket can carry out circulating cooling of the glue outlet, improve the hot nozzle cooling efficiency, and improve product quality.
Description
technical field [0001] The invention relates to the field of hot nozzle cooling devices in injection molds, in particular to a circulating cooling water jacket. Background technique [0002] In the process of plastic injection molding, the cooling section takes the most time in a molding cycle, and it needs to directly cool the hot nozzle to improve the molding production efficiency; the cooling water jacket currently used is roughly a hollow cylindrical water jacket, and the water jacket is placed on the hot nozzle. On-mouth cooling of hot nozzles, see figure 1 As shown, there is a water tank 3 on the outside of the water jacket body 1, and the cooling water flows in the water tank 3 without directionality, which is prone to stagnant water, and the cooling effect is not ideal, and the water tank 3 is far away from the rubber port 2, and the cooling effect on the hot nozzle is not good. . Contents of the invention [0003] The technical problem mainly solved by the p...
