A method of optimizing a door trim injection molding process is disclosed. The purpose of an embodiment of the present invention is to provide a method of optimizing the door trim injection molding process, which optimizes mold and process conditions when manufacturing a door trim by injection molding. The method according to an embodiment of the present invention comprises: a door trim equivalent model defining step of calculating equivalent thickness and shape factor of a speaker grill by using an equivalent model of the door trim, calculating reference shape information corresponding to a shape of the speaker grill by using the calculated equivalent thickness and a shape factor, and reflecting the calculated reference shape information to define door trim information; a door trim mold designing step of designing a mold by using the door trim information defined in the door trim equivalent model defining step; and a door trim injection process condition optimizing step of optimizing injection process conditions of the door trim designed in the door trim mold designing step, wherein the door trim injection process condition optimizing step obtains a design value of the injection process conditions at which deterioration index according to position of a weld line of the designed door trim and sharpness of the weld line are minimized.

    도어트림 사출 성형 프로세스 최적화방법이 개시된다. 본 발명의 일실시예에 따른 도어트림 사출 성형 프로세스 최적화방법은 도어 트림의 등가모델을 이용하여 스피커 그릴의 등가두께와 형상계수를 산출하고, 상기 산출된 등가두께와 형상계수를 이용하여 상기 스피커 그릴 형상에 대응하는 기준형상정보를 산출하고, 상기 산출된 기준형상정보를 반영하여 도어 트림 정보를 정의하는 도어트림 등가모델 정의단계와, 도어트림 등가모델 정의단계에서 정의된 도어 트림 정보를 이용하여 금형 설계하는 도어 트림 금형 설계단계 및 도어 트림 금형 설계단계에서 설계된 도어 트림의 사출공정조건을 최적화하는 도어트림 사출공정조건 최적화단계를 포함하고, 도어트림 사출공정조건 최적화단계는, 설계된 도어트림의 웰드라인의 위치에 따른 악화지수와 웰드라인의 선명도가 최소화되는 사출공정조건의 설계값을 얻는다.
