Abstract
소정 두께를 구비한 물품을 성형시키기 위하여 본 발명은 상기 사출품의 두꺼운 부분을 중공형체로 성형시킬 수 있도록 용융 상태의 수지를 미충진 상태로 몰드에 주입시킨 후 상기 몰드에 소정 압력으로 불활성 가스를 주입시키는 단계를 포함하는 방법을 제공한다.In order to mold an article having a predetermined thickness, the present invention injects a molten resin into an unfilled mold so that a thick portion of the injection molded product can be formed into a hollow body, and then inert gas is applied to the mold at a predetermined pressure. It provides a method comprising the step of injecting.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.
제1도는 종래의 몰드 내부에 주입되어 있는 수지의 표면상에 함몰부가 형성되어 있는 것을 개략적으로 도시한 단면도,1 is a cross-sectional view schematically showing that the depression is formed on the surface of the resin injected into the conventional mold,
제2도는 종래의 사출 성형의 보압 공정중 각각의 위치에서의 압력 발생과 시간과의 관계를 개략적으로 나타낸 그래프,2 is a graph schematically showing the relationship between pressure generation and time at each position in the packing process of a conventional injection molding,
제3도는 본 발명에 따른 사출 성형 방법을 순차적으로 나타낸 흐름도.3 is a flow chart sequentially showing the injection molding method according to the present invention.
