  • Hot runner injection molding machine
    Patent number: 5225211
    Abstract: A hot runner injection molding machine which injects a melt into a cavity formed by a front mold and a movable rear mold. The injection molding machine includes a runner device fixed to a fixed head, gate devices which form orifices through which the melt is injected into the cavity, and heaters for heating the gate devices and detachably attached to the runner device. The gate devices and the heaters can be changed in accordance with the type of molds to be used, without removing or dismantling the runner device, and therefore, the same runner device can be commonly used for different types of molds.
