Abstract

The invention discloses an injection molding method and structure for a hot runner of an automobile bumper deflector, and relates to the technical field of automobile part manufacturing, the injection molding structure comprises an injection molding mechanism, a cooling mechanism is arranged at the bottom of the injection molding mechanism, a demolding mechanism is arranged in the injection molding mechanism, and the injection molding mechanism comprises an upper mold; a lower die is arranged at the bottom of the upper die, and cooling grooves are formed in the side wall and the bottom of the lower die. According to the hot runner injection molding structure for the flow guide plate of the automobile bumper, a conveying pump works and is matched with a water pumping pipe to pump out cooling liquid in a cooling water tank, then the cooling liquid is conveyed to a flow dividing pipe through a conveying pipe, is uniformly distributed to an inner spraying pipe and an outer spraying pipe through the flow dividing pipe, and is further conveyed to a transverse spraying pipe in the outer spraying pipe; the inner spraying pipe is used for spraying and cooling on the inner wall of the lower mold, and meanwhile, the outer spraying pipe and the transverse spraying pipe are used for further spraying and cooling on the outer wall of the lower mold, so that the cooling efficiency of the mold is effectively improved.
