A clamping unit of an injection molding machine for producing multicolored cast pieces has a pair of mold halves, one of which defines at least two separate mold hollows for the cast piece, and complementary hollows or cores defined in the other mold half for forming at least two cavities in the mold. One of the cavities is configured to the shape of one colored component to the article.* (*The other has the configuration of the whole two colored cast piece.) The clamping unit has stationary and movable mold clamping plates. A turning plate is rotatably connected to one of the clamping plates for rotatably mounting one of the mold halves to the respective clamping plates. A fluid piston and cylinder arrangement is used to rotate the rotatably mounted mold half 180 DEG between injections. The ejector is eccentrically mounted with respect to the injection axis and may be mounted in different locations on the clamping plate. |
