Description

This invention relates to the technical field of hot runners, and more specifically, to a balanced two-channel flow divider plate and a hot runner. Hot runners are widely used in injection molding and are an important component of injection molds. Referring to Figures 1, 2, 3, 4, and 5, in the conventional technology, a main runner 2 and a bent runner 3 are provided within the flow divider plate 1 of the hot runner. The valve pin 4 penetrates the bent hole 3 of the flow divider plate 1, and a stagnation region a exists when the resin passes behind the valve pin 4, which is unfavorable for color changes in the resin product. Furthermore, the resin in the main runner 2 impacts the valve pin 4 from one side at the location of the bent runner 3, causing a slight bend in the valve pin 4. As a result, an imbalance b occurs between the tip of the valve pin 4 and the gate bush 5 of the hot nozzle, accelerating damage to the gate component when the valve pin 4 seals the resin. The damaged gate component then causes gate burr defects on the resin product. The objective of this invention is to provide a balanced two-channel flow divider plate and a hot runner that solve the technical problems of the prior art, in which a stagnation region exists when the resin passes through the back surface of the valve pin, and where imbalance occurs between the tip of the valve pin and the gate bush of the hot nozzle when the resin impacts the valve pin from one side.
