Abstract

본 발명은 시작품용 자동차 램프렌즈에 제조방법에 관한 것으로 램프렌즈(14)의 볼록부분과 렌즈부분을 일체로 성형할 수 있도록 상형인 실리콘 고무형(7′)에 수지모형(5)에 의해 음각형태인 파형요부(4)가 성형되게 하여 하형인 실리콘 고무형(7)과 합형하여 열경화성투명수지(11)를 주입하여 램프렌즈를 제조하므로서 램프렌즈의 볼록부분과 렌즈부분을 일체로 형성하여 성형작업이 용이하고 대량생산에 유리할 뿐만 아니라 제품품질의 균일성을 유지하여 제품품질을 향상시키고 양산을 위한 정확한 설계검증을 할 수 있어 양산시 발생되는 오차 및 설계변경 등을 줄일 수 있는 것이다.The present invention relates to a manufacturing method for a prototype automotive lamp lens, which is engraved by a resin model (5) in a silicon rubber mold (7 '), which is an upper mold, so that the convex portion and the lens portion of the lamp lens (14) can be integrally formed. The concave portion and the lens portion of the lamp lens are integrally formed by injecting the thermosetting transparent resin 11 and integrating with the lower silicone rubber mold 7 to form the corrugated recess 4 having a shape. It is easy to work and advantageous to mass production, and can maintain product uniformity to improve product quality and make accurate design verification for mass production, thereby reducing errors and design changes that occur during mass production.
