Title
(EN) INJECTION MOLDING PARTS WITH FASTENER ELEMENTS
(FR) PARTIES DE MOULE POUR INJECTION AVEC ELEMENTS DE FIXATION
Abstract
(EN)
An injection mold (2) and a method for ejecting, from the mold, a molded product (4) having an array of integrally molded fastener elements (6) extending from a base (8) are provided. In some embodiments, the mold (2) includes a series of ejector pins (24) which progressively eject the product (4). In other embodiments, the mold (2) includes moveable parts which pull fastener elements (6) out of mold cavities (16) without the use of ejector pins (24).
(FR)
L'invention concerne un moule pour injection (2) et un procédé permettant d'éjecter un produit moulé dudit moule (4). Le produit moulé comprend un ensemble d'éléments de fixation (6) moulés d'un seul tenant, s'étendant depuis une base (8). Selon certains modes de réalisation, le moule (2) comprend une série de tiges d'éjection (24) qui éjectent progressivement le produit (4). Selon d'autres modes de réalisations, ledit moule (2) comprend des parties mobiles qui tirent des éléments de fixation (6) hors des cavités de moule, sans utiliser de tiges d'éjection (24).
