Title (EN) EJECTOR INTENDED FOR SUBMARINE RUNNERS LOCATED ON THE FIXED PARTS OF THERMOPLASTIC INJECTION MOULDS
(ES) EXPULSOR PARA COLADA SUBMARINA EN PARTES FIJAS DE MOLDES DE INYECCIÓN TERMOPLÁSTICOS
(FR) ÉJECTEUR POUR COULÉE SOUS-MARINE DANS DES PARTIES FIXES DE MOULES D'INJECTION THERMOPLASTIQUES
Abstract:
(EN) The invention consists of: a metal rod (1) made from tempered, nitrided steel, having a size and geometrical shape that vary depending on the size of the runner and the thermoplastic part to be ejected, with cylindrical models being the most commonly used; a lower body (2); and a mushroom-shaped head (3) which represents the main characteristic of the invention and prevents functional wear due to friction, reducing the high risk of damage to the mould, as well as providing the resulting savings in time and money.
(ES) Está formado por una varilla (1) metálica de acero templado y nitrurado, de dimensión y forma geométrica variables, en función del tamaño de Ia colada y de Ia pieza termoplástica a extraer, siendo el modelo cilindrico el más utilizado, un cuerpo inferior (2), y un cabezal (3) fungiforme que representa Ia característica principal de Ia invención, y que evita el desgaste funcional por rozamiento, disminuyendo el alto riesgo de daño sobre el molde, con el consiguiente ahorro de coste en tiempo y dinero.
(FR) La présente invention concerne une tige métallique (1) en acier trempé et nitruré, ayant une dimension et une forme géométrique variables, dépendant de la taille de la coulée et de la pièce thermoplastique à éjecter, le modèle cylindrique étant le plus utilisé; un corps inférieur (2) et une tête (3) fongiforme qui constitue la caractéristique principale de l'invention et qui empêche l'usure fonctionnelle par frottement, ce qui réduit le risque élevé d'endommagement du moule et par conséquent économise du temps et de l'argent.
