Title (EN) UNDERCUT TREATMENT MECHANISM, MOLDING DIE AND MOLDED ARTICLE
(FR) MÉCANISME DE TRAITEMENT DE CONTRE-DÉPOUILLE, MATRICE DE MOULAGE ET ARTICLE MOULÉ
(JA) アンダーカット処理機構、成形用金型及び成形品
Abstract:
(EN) The present invention provides: an undercut treatment mechanism which can be designed to have a compact configuration while enabling easy stripping of an undercut part and which is capable of improving the quality of a molded article; a molding die; and a molded article. Provided is an undercut treatment mechanism 10 which is used by being mounted to a molding die 1 for molding a molded article P having an undercut part P1 and which enables stripping of the undercut part P1, the undercut treatment mechanism being provided with: a push-up piece 30 which is capable of moving in the stripping direction of the molded article P; a sleeve pin 60 which is fixed to or integrally formed with the push-up piece 30 and which is capable of supporting the undercut part P1 when the push-up piece 30 is in motion; a slide piece 40 which is capable of sliding with respect to the push-up piece 30 and which moves in a direction intersecting with the stripping direction of the molded article P in tandem with the movement of the push-up piece 30; and a holding piece 50 which slidably holds the slide piece 40.
(FR) La présente invention concerne un mécanisme de traitement de contre-dépouille qui peut être conçu pour avoir une configuration compacte tout en permettant un démoulage aisé d'une partie en contre-dépouille et qui est capable d'améliorer la qualité d'un article moulé; une matrice de moulage; et un article moulé. Le mécanisme de traitement de contre-dépouille (10) est utilisé en étant monté sur une matrice de moulage (1) pour mouler un article moulé (P) ayant une partie en contre-dépouille (P1), et permet le démoulage de la partie en contre-dépouille (P1), le mécanisme de traitement de contre-dépouille étant pourvu d'une pièce de poussée (30) pouvant se déplacer dans la direction de démoulage de l'article moulé (P); d'une broche en manchon (60) qui est fixée à la pièce de poussée (30) ou formée d'un seul tenant avec celle-ci et qui est capable de supporter la partie en contre-dépouille (P1) lorsque la pièce de poussée (30) est en mouvement; d'une pièce coulissante (40) qui est capable de coulisser par rapport à la pièce de poussée (30) et qui se déplace dans une direction croisant la direction de démoulage de l'article moulé (P) conjointement avec le mouvement de la pièce de poussée (30); et d'une pièce de maintien (50) qui maintient de manière coulissante la pièce coulissante (40).
(JA) コンパクトに構成可能でありながらアンダーカット部を容易に型抜き可能であり、成形品質を向上可能なアンダーカット処理機構、成形用金型及び成形品を提供する。 アンダーカット部P1のある成形品Pを成形する成形用金型1に取付けられ使用される、アンダーカット部P1を型抜き可能とするアンダーカット処理機構10であって、成形品Pの型抜き方向に移動可能な押上駒30と、押上駒30に固定又は一体的に形成され、押上駒30の移動時にアンダーカット部P1を支持可能なスリーブピン60と、押上駒30に対して摺動可能であり、押上駒30の移動に連動して成形品Pの型抜き方向と交差する方向に移動する摺動駒40と、摺動駒40を摺動可能に保持する保持駒50と、を備える。
