CA 2641097

An injection mold including a connecting structure for separating confronting faces of a slide member and a mold base, respectively, during a movement of the slide member. In accordance with several embodiments of the invention, the connecting structure may include a compressible member such that the slide member is biased away from the mold base, and wherein a positive contact between the confronting surfaces is configurable in response to an applied clamping force between the slide member and the mold base. In accordance with an alternative embodiment of the invention a cam arrangement links the slide member and the mold base enabling a positive contact between the confronting surfaces when the slide member is arranged in the in-mold position, and providing a gap between the confronting surfaces during at least a portion of an interval when the slide member is moving.

Moule d'injection comprenant une structure de connexion servant à séparer des faces en regard d'un élément coulissant et d'une embase de moule, respectivement, pendant un mouvement de l'élément coulissant. En accord avec plusieurs modes de réalisation de l'invention, la structure de connexion peut comprendre un élément compressible, de sorte que l'élément coulissant est sollicité pour s'écarter de l'embase du moule, un contact positif entre les surfaces en regard pouvant être configuré en réponse à un effort de serrage appliqué entre l'élément coulissant et l'embase du moule. En accord avec une variante du mode de réalisation de l'invention, un dispositif à came relie l'élément coulissant à l'embase du moule, permettant un contact positif entre les surfaces en regard lorsque l'élément coulissant est disposé dans la position à l'intérieur du moule, et donnant un espace entre les surfaces en regard pendant au moins une partie d'un intervalle au cours duquel l'élément coulissant est en mouvement.
