The hot runner technology is an excellent means for shortening the injection molding period and saving materials. After each injection of the hot runner mold is completed, the runner colloid can not be solidified under the heating of the heating device, so that a runner nozzle is not required to be removed in product demolding, and the injection runner is still communicated at the beginning of the next injection molding period. Waste heat is discharged in time, cooling of a pouring channel system is not limited, cooling time is only affected by product cooling, and therefore the injection molding period is reduced to a certain extent. The 3D printing water jacket (hot nozzle sleeve) is added at the hot runner nozzle filling position and used for controlling the temperature of the glue inlet, reducing the temperature difference among all parts, improving the injection molding effect and greatly reducing the cooling time of products by the 3D printing technology. The uniform cooling effect greatly reduces the shearing heat effect, and more products can be produced in one die without deformation. The product quality of one mould with four cavities can only be ensured in the traditional mould manufacturing, and the product deformation caused by the problems of poor cooling and the like can be serious due to the continuous increase of the cavities. After the 3D printing conformal waterway technology is utilized, the quality can be guaranteed, meanwhile, the four cavities of the mold are lifted to the sixteen cavities of the mold, and the injection molding period is shortened by about 48%, so that the comprehensive productivity can be improved by about five times.
