METHOD OF OPTIMIZING DOOR TRIM INJECTION MOLDING PROCESSING

摘要

A door trim injection molding process optimization method is disclosed. The door trim injection molding process optimization method according to an embodiment of the present invention calculates the equivalent thickness and shape coefficient of the speaker grill using the equivalent model of the door trim and calculates the equivalent thickness and shape coefficient of the speaker grill using the calculated equivalent thickness and shape coefficient, A door trim equivalent model definition step of calculating reference trim information corresponding to the shape and defining the door trim information by reflecting the calculated reference shape information; And a door trim injection process condition optimization step of optimizing an injection process condition of a door trim designed in a door trim mold design stage, wherein the door trim injection process condition optimization step includes a step of optimizing a door trim injection process condition of the door trim, Of the injection process condition in which the deterioration index according to the position of the weld line and the sharpness of the weld line are minimized To obtain a threshold.
