When the injection devices 8, 8 are moved to connect to the stopped intermediate movable plate 6, the injection devices 8, 8 are moved to connect to the stopped intermediate movable plate 6, and therefore the rear movable plate 2 is moved to the intermediate movable plate 6. Since the connection of the injection device 8 is completed when it comes into contact with the movable platen 6, the mold clamping device 3 can immediately increase the pressure to the mold clamping force after the rear movable platen 2 stops, and thus the pre-metered injection The molten resin in the devices 8, 8 is transferred to injection nozzles 10, 10.
The mold is then press-fitted into the mold cavities 6b, 6b from the hot runner gate through the hot runners 6c, 6c of the intermediate movable platen 6, and after the molding, the mold opening/closing cylinder 7 and the mold clamping device 3 are used in combination. The molds are sequentially opened and the products are taken out in preparation for the next injection.

れる効果を有する。 According to the present invention, two hot runners are formed on the intermediate movable plate disposed between the fixed plate and the rear movable plate to touch the nozzles to the two injection devices on the sides thereof. Since the molds connected to the runner are protruded from the front and rear, there is no need to particularly specialize the molds at the front and rear of the intermediate movable plate, as in the conventional example mentioned above, and the combination of conventional molds can be used. This makes it possible to simultaneously process different materials, colors, and shapes for each product, which has the effect of providing a processing system that is highly compatible with conventional injection molding machines.
