Continuous molding apparatus includes a raw material supplying portion, a mixing portion, a molding portion, a mixture delivery portion, a supporting portion and a control portion. Each reservoir of the raw material supplying portion is independently connected to an inlet of the mixing portion. The molding portion includes a plurality of spaced rotatable mold assemblies, each with at least two retractable mold sections. The mixture delivery portion is selectively alignable with each mold assembly sequentially in a preselected repeating cycle through an indexing mechanism.

Continuous molding apparatus including a raw material supplying portion, a mixing portion, a molding portion, a mixture delivery portion, a supporting portion and a control portion; said raw material supplying portion including a plurality of reservoirs; said mixing portion including an elongated chamber, a plurality of spaced deflector sections disposed along the length of said elongated chamber, reservoirs of said raw material supplying portion being independently connected to inlets of said mixing portion through flexible connector means; said molding portion including a plurality of spaced enclosed mold assemblies, each of said mold assemblies including at least two retractable mold sections, and mold section orienting and interlocking means; said mixture delivery portion including a hollow probe member selectively connectable with an outlet of said mixing portion; said mixture delivery portion being selectively alignable with each enclosed mold assembly sequentially in a preselected repeating cycle; said supporting portion including indexing means providing said selective and repeating alignment between said mixture delivery portion and each of said mold assemblies, said supporting portion including support sections rotatably carrying each of said mold assemblies; said control portion including drive means moving said indexing means, said mold section orienting and interlocking means and the rotation of said mold assemblies in a preselected rotational profile, valve means and flow monitoring means disposed along the length of each of said connector means, programmable memory means controlling said drive means and valve means, and actuating means responsive to said memory means activating said drive means and said valve means. A continuous molding method including the steps of positioning a plurality of separable section enclosed mold assemblies in a preselected arrangement with spacing therebetween, axially aligning sequentially a mixture delivery assembly with each of said mold assemblies, during each alignment performing the steps of continuously rotating said aligned mold assembly in a preselected rotational profile, dispensing a freshly prepared foamable resin-forming liquid mixture through a probe member disposed in an enclosed cavity of said aligned mold assembly, withdrawing said probe member in a preselected rate profile while continuously dispensing said resinforming mixture therefrom in a preselected flow rate profile, spreading said mixture within said cavity by centrifugal force, continuing said rotation of said mold assembly while said mixture forms a foam therein completely filling said mold cavity, displacing air in said cavity with said foam and exhausting said air along the outside of said probe member, monitoring the delivery of said liquid mixture into said mold cavity and coordinating same with the flow of raw materials, the mold assembly rotation and the withdrawal of said probe member, separating said mold sections of each mold assembly after said probe member is withdrawn completely therefrom, removing a molded foamed resin product from said separated mold sections, closing said mold sections, inserting said probe member therein and repeating said cycle to form a multiplicity of such molded products on a continuing basis.
