Title
(EN) RESIN COMPONENT AND METHOD FOR MANUFACTURING SAME
(FR) COMPOSANT DE RÉSINE ET SON PROCÉDÉ DE FABRICATION
(JA) 樹脂部品及びその製造方法
Abstract
(EN)
This resin component includes a plate-like molded article body (1) that comprises an injection molded article, wherein, among the planar surfaces of the molded article body (1), the surface on the reverse side of the surface on which surface accuracy is required serves as a pressed surface that is pressed by a movable core for pressing, and a parting line formed by the movable core on the pressing surface exhibits the relationship (t/4) ≤ x ≤ (3t/2), where x is the distance dimension from an end edge part of the molded article body (1), and t is the thickness dimension of the molded article body (1).
(FR)
Ce composant de résine comprend un corps d'article moulé en forme de plaque (1) qui comprend un article moulé par injection, dans lequel, parmi les surfaces planes du corps d'article moulé (1), la surface sur le côté inverse de la surface sur laquelle la précision de surface est requise sert de surface pressée qui est pressée par un noyau mobile pour un pressage, et une ligne de séparation formée par le noyau mobile sur la surface de pression présente la relation (t/4) ≤ x ≤ (3t/2), où x est la dimension de distance à partir d'une partie de bord d'extrémité du corps d'article moulé (1), et t est la dimension d'épaisseur du corps d'article moulé (1).
(JA)
樹脂部品は、射出成形品からなる板状の成形品本体(1)を含むものであって、前記成形品本体(1)の板面のうち、面精度が必要な面とは反対側の面が、加圧用の可動入子による加圧面とされていると共に、当該加圧面において前記可動入子により形成される分割線は、前記成形品本体(1)の端縁部からの距離寸法xが、該成形品本体(1)の厚み寸法tに対し、 (t/4)≦x≦(3t/2) の関係とされている。
