Abstract:
Multiaxis rotational molding apparatus including a support portion, a molding portion, a mixing portion and a control portion; said support portion including an upstanding frame section, a plurality of spaced generally horizontally oriented arm members each having one end extending from said upstanding frame section; said molding portion including a plurality of mold supporting assemblies with one supporting assembly rotatably mounted adjacent a free end of each of said arm members, each of said mold supporting assemblies including an independently rotatable mold connector section, each of said mold supporting assemblies including a central passage therethrough from a rotatable connection with said arm member and through said mold connector section, a plurality of mold assemblies each including a plurality of separable mold sections forming a substantially enclosed cavity, connecting means selectively securing said mold sections of one mold assembly together and to said mold connector section; said mixing portion including a plurality of independently movable elongated mixing chambers adjustably mounted on said frame section adjacent said mold assemblies, each of said mixing chambers including a plurality of adjacent axially aligned rotatable mixing sections, independent drive means rotating each of said mixing sections about a central axis; said control portion including indexing means disposed on said frame section sequentially orienting each of said mixing chambers with each mold cavity, actuating means rotating each mold connector section and said mold assembly affixed thereto and actuating means pivoting each mold supporting assembly and said mold assembly affixed thereto with respect to said arm member, programmable memory means storing preselected operating parameters, monitoring means sensing operating information from control components, circuitry transmitting signals from said monitoring means to coordinating means comparing said operating information with said operating parameters stored in said memory means and activating said indexing means and said actuating means to control formation of molded structures with said molding apparatus continuously in a preselected multiaxis molding profile.
