Abstract

PURPOSE:To obtain a metallic mould equipped with a hot runner and provided with a mixing device which takes static mixing effect to resin fluid section so that molten resin can be uniformly mixed when it flows in the mould and unevenness in color phase can be prevented. CONSTITUTION:Molten resin is made to flow from a forming machine's nozzle 15 into a cavity 12 passing through a runner 10 section of a manifold 2 and a gate 11. When the molten resin is passing through the runner 10 section, it is uniformly mixed by a mixing device 9. A heater 8 and a temperature sensor 7 keep the manifold 2 at an appropriate temperature to smooth flow of molten resin and also mixing at the mixing device 9. After cooling and solidification of formed resin product in the cavity 12, the mould is separated into a fixed side metallic mould 1 and a movable side metallic mould 13, and the formed product adhering to the movable side is taken out by being stuck out with a pin 14.
