More Information
Summary:An injection blow mold machine having a rotary wheel indexing means adapted to be indexed and precisely positioned in a simple manner and further adapted to be used in conjunction with simplified injection pressure resistance means and simplified air inlet means, all of the injection blow molding apparatus being adapted to be utilized in a modified conventional injection molding machine. The rotary wheel indexing means comprises a central portion with radial arms extending therefrom and core rods mounted perpendicularly on said radial arms. Compressive force limiting means interposed between the blow mold and the movable platen on which the movable injection and blow mold halves are mounted distributes a disproportionately greater stress to the injection mold than to said blow mold. Still other unique features of the machine include a 360 DEG -180 DEG limit switch and precise and simple means for positioning molds in the apparatus mold receiving members.
