Abstract
(EN)
A die for injection molding comprising: a flow path (63) through which a molten resin flows; a main body part (61) which has an introduction part for introducing the molten resin to the flow path (63) and a supply part (65) supplying the molten resin from the flow path (63) to a cavity mold (30); and plug units (62), (69) which have a plug flow path (67) formed therein and can be attached to the main body part (61), said plug flow path (67) being a part of the flow path (63), wherein a suppression part (80), which suppresses pressure loss from occurring when the molten resin flows through the flow path (63), is formed at a location in the plug flow path (67) where an advancing direction of the molten resin changes.
(FR)
La présente invention concerne une matrice pour moulage par injection qui comprend : un trajet d'écoulement (63) à travers lequel s'écoule une résine fondue; une partie de corps principal (61) qui présente une partie d'introduction pour introduire la résine fondue dans le trajet d'écoulement (63) et une partie d'alimentation (65) alimentant la résine fondue à partir du trajet d'écoulement (63) vers un moule de cavité (30); et des unités piston (62), (69) qui comportent un trajet d'écoulement piston (67) formé dans celui-ci et pouvant être fixé à la partie de corps principal (61), ledit trajet d'écoulement piston (67) étant une partie du trajet d'écoulement (63), une partie de suppression (80), qui empêche la perte de pression de se produire lorsque la résine fondue s'écoule à travers le trajet d'écoulement (63), est formée à un emplacement dans le trajet d'écoulement piston (67) où une direction d'avancement de la résine fondue change.
