Title
(EN) INJECTION MOLD OF A PLASTIC PREFORM
(FR) MOULE D'INJECTION D'UNE PRÉFORME EN PLASTIQUE
Abstract
(EN) An injection mold (9') of a plastic preform comprising a first part (12) and a second part (13), fixed to each other, and a third part (14); wherein the third part (14) is provided with a molding cavity (41') defining an axis (Υ') and is adapted to be integrally fixed to a first surface of a supporting frame of the mold; wherein the second part (13), arranged between the third part and the first part, is adapted to slide along said axis to close or open the cavity; wherein the first part (12) comprises a longitudinal rod (55) adapted to slide along said axis (Υ') through a second surface of the supporting frame, opposite to and spaced apart from the first surface; wherein the second part (13) is provided with: - a guiding cage comprising a first plate (18), provided with a through hole through which the longitudinal rod can slide and configured to abut on said second surface; a structure (18"); parallel guiding rods (16) fixed at a first end thereof to said first plate and fixed at a second end thereof to the structure, - an assembly (19, 18', 49) sliding inside said cage, fixed at a first end thereof to the rod by means of quick-coupling means (15), and comprising at a second end thereof a punch (59) sliding inside the structure and defining a first complementary component of the cavity, wherein the structure (18") is provided with two half-collars (66', 66") and is configured so as to define, together with the punch, a cam system for opening or closing the two half-collars which define, when closed, a second complementary component of the cavity.
(FR) Moule d'injection (9') d'une préforme en plastique comprenant une première partie (12) et une deuxième partie (13), fixées l'une à l'autre, et une troisième partie (14). La troisième partie (14) est pourvue d'une cavité de moulage (41') délimitant un axe (Υ') et est conçue pour être fixée d'un seul tenant à une première surface d'un cadre de support du moule; la deuxième partie (13), agencée entre la troisième partie et la première partie, est conçue pour coulisser le long dudit axe pour fermer ou ouvrir la cavité; la première partie (12) comprend une tige longitudinale (55) conçue pour coulisser le long dudit axe (Υ') à travers une deuxième surface du cadre de support, opposée à la première surface et espacée de cette dernière; la deuxième partie (13) est pourvue : - d'une cage de guidage comprenant une première plaque (18), pourvue d'un trou débouchant par lequel la tige longitudinale peut coulisser et configurée pour s'appuyer sur ladite deuxième surface; une structure (18''); des tiges de guidage parallèles (16) fixées par une première extrémité à ladite première plaque et fixées par une deuxième extrémité à la structure, - un ensemble (19, 18', 49) coulissant à l'intérieur de ladite cage, fixé par une première extrémité à la tige à l'aide d'un moyen d'accouplement rapide (15), et comprenant, à une deuxième extrémité, un poinçon (59) coulissant à l'intérieur de la structure et délimitant un premier composant complémentaire de la cavité. La structure (18'' est pourvue de deux demi-colliers (66', 66'') et est configurée de manière à délimiter, avec le poinçon, un système de came pour ouvrir ou fermer les deux demi-colliers qui délimitent, lorsqu'ils sont fermés, un second composant complémentaire de la cavité.
