The hot runner 5 is heated to ensure that the plastic in the runner and the sprue is kept in a molten state. Because the heating rod and the heating ring are arranged near or in the center of the runner, the whole runner from the nozzle outlet of the injection molding machine to the feed inlet 6 is in a high-temperature state, so that the plastic in the runner is kept molten, the runner does not need to be opened to take out the condensate after the machine is stopped, and the runner 5 only needs to be heated to the required temperature when the machine is started again. Thus, the hot runner 5 process is sometimes referred to as a hot manifold system, or as a runner-less molding.
During injection molding production, an injection mold is installed on an injection molding machine, a driving structure on the injection molding machine drives a movable mold component 3 to move relative to a fixed mold component 2, the opening and closing actions of the injection mold are completed, during injection, the injection molding machine injects plastic in a molten state into a hot runner 5 from a feed inlet 6, the plastic enters the hot runner 5, different feeding sequences are realized at different positions in a product cavity according to different feeding states of a feeding mechanism 4, the feeding state of the feeding mechanism 4 can be two or more, and description is mainly performed aiming at the conditions of the two feeding states in the scheme.

Because if the fender structure is more complicated and the cavity 1 outer wall is fed, the feeding time of the structure is too long due to the complex structure of the cavity 1 outer wall, the plastic heat in a molten state is dissipated quickly, and the fender has a welding mark or takes materials.
