    摘要: A blow molding apparatus comprising a wheel mounted rotationally on a base for rotating a plurality of molds past an extrusion die. The wheel is comprised of a hub mounted to a rotational shaft and a plurality of disk segments mounted about the hub to carry the plurality of molds. The disk segments may be individually selectively secured to the hub to facilitate simple replacement of disk segments.

    摘要: A blow molding apparatus having a mold clamping apparatus of the clam shell type, and having a linkage controlling the opening and closing of the mold, the linkage being comprised of two links pivotally connected to each other and driven by a pneumatic or hydraulic cylinder. The links are configured to provide the cylinder with mechanical advantage so that little mold separation force is recognized at the cylinder.

    摘要: A multilayer injection nozzle assembly, for use with an injection molding machine, to form a multilayer injection molded article comprising an inner nozzle, a middle nozzle and an outer nozzle. The inner nozzle has a first hole which communicates with a first channel in the inner nozzle and for receiving a flow of a first material from the injection molding machine. The inner nozzle also has a second hole which communicates with a second channel in the inner nozzle for receiving a flow of a second material from the injection molding machine. The first channel communicates with an inner and an outer channel in the inner nozzle, whereby the first material flows from the first channel into both the inner channel and the outer channel. The first material that flows into the inner channel will flow out of the nozzle assembly to form a first layer of the injection molded article and the material that flows into the outer channel will flow out of the nozzle assembly to form a second layer of the injection molded article.
