Component of an injection molding apparatus

A component of an injection molding apparatus to divert a flow of molten plastic material from a supply channel to an injection channel coaxially crossed by a shutter, said supply channel and said injection channel being transversal to each other and produced inside a manifold of said apparatus, said component comprising a body provided with

• a central part crossed by a through hole, defining a longitudinal axis, for a passage of said shutter;
• a first bulkhead protruding from said central part, distal from an end edge of the through hole and adapted to be arranged at one end of the supply channel for dividing a flow of molten plastic material coming from said supply channel into two flow portions;
• a second bulkhead and a third bulkhead, said second bulkhead and said third bulkhead protruding in a diametrically opposite manner to each other from said central part, separated from each other by the through hole and proximal to said end edge of the through hole, and adapted to be arranged at one end of the injection channel to accompany said two flow portions in said injection channel;
• wherein the first bulkhead is arranged on a same side as the third bulkhead with respect to said central part,
• wherein at least one first lateral surface and at least one second lateral surface are arranged at a first side and a second side, opposite the first side, of said first bulkhead, respectively, to accompany said two flow portions from said first bulkhead toward the second bulkhead and the third bulkhead,
• wherein the first bulkhead has a first end edge which is distal from the central part,
• and wherein a thickness of the first bulkhead gradually increases from the first end edge towards said central part;
• wherein the second bulkhead has a second end edge and the third bulkhead has a third end edge, said second end edge and said third end edge being transversal to said longitudinal axis;
• wherein a hollow peripheral part is provided, coaxial to the longitudinal axis and containing the central part therein, said hollow peripheral part having a first opening, divided in two by the first end edge and adapted to communicate with the supply channel, and a second opening divided in two by the second end edge, by the third end edge and by the end edge of the through hole, and adapted to communicate with the injection channel,
• and wherein the at least one first lateral surface and the at least one second lateral surface are inner surfaces of said hollow peripheral part,
• whereby two paths are defined inside the hollow peripheral part, one for each flow portion, each path being delimited at least by the first bulkhead, by the at least one first or at least one second lateral surface, by the central part, by the second bulkhead and by the third bulkhead.
