    • A color changing apparatus of an injection molding hot runner die which is simple in construction and easily capable of changing colors for molding products without removing and replacing a hot runner. In the apparatus, a passage for supplying a melted resin to a molding die, a divided type hot runner block is provided with hot runners each for exclusive use of each of molding colors, sprues and nozzles being in communication with the hot runners. A moving device is provided for moving the molding die, which is united with the divided type hot runner block, along with the divided type hot runner block. A positioning device is adapted to place the molding die in position in a state where either of the sprues of the divided type hot runner block is moved by the moving device to a position opposed to an injection nozzle for injecting the melted resin.
    • 注塑热流道模具的变色装置,结构简单,并且容易地能够改变成型产品的颜色而不移除和更换热流道。 在该装置中,用于将熔融树脂供给到成型模具的通道,分割型热流道块设置有热流道,每个热流道专门用于与热流道连通的每种模塑颜色,浇口和喷嘴。 提供了一种移动装置,用于与划分型热流道块一起移动与分型热流道块结合的成型模具。 定位装置适于将分模型热流道块的浇口中的任何一个移动装置移动到与喷射熔融树脂的喷嘴相对的位置的状态。
