Abstract

L'invention est relative à un moule d'injection. Dans le moule, dont la tubulure d'injection présente un corps extérieur se rétrécissant coniquement vers son extrémité libre et un élément de noyau mobile axialement pour modifier l'épaisseur de l'espace annulaire d'injection, la paroi latérale de l'élément de noyau mobile est cylindrique jusqu'à son extrémité libre. Le moule est applicable à la fabrication de tuyaux en matière plastique de différents diamètres.The invention relates to an injection mold. In the mold, the injection nozzle of which has an outer body tapering conically towards its free end and a core element movable axially to modify the thickness of the annular injection space, the side wall of the injection element mobile core is cylindrical up to its free end. The mold is applicable to the manufacture of plastic pipes of different diameters.
