Abstract
Apparatus for mixing fluent materials, especially components for foundry molding compositions, affording a pluralities of containers feeding serially one to another or in parallel discharging to a common acceptor, for batch or continuous operations, permitting simultaneous mixing of all components, either all brought together at once or, as for reactive component mixing, in parallel diverse component group mixing flows, joined for final mixing bringing the reactive components together; and an agitated shooter injector vessel receiving the mixed material, pneumatically actuated to expel material into a mold or the like.
Claims16
A mixing apparatus for mixing fluent materials, particularly foundry molding materials, comprising:
- a horizontal base and a plurality of at least two mix vessels secured on the base;
- each mix vessel having a vertical circumferentially enclosing side wall and containing respective mixing means;
- said base being resiliently mounted by means permitting orbital oscillation to the base, and therewith to each vessel oscillation about a respective vertical axis located within the confines of the vessel;
- driving means imparting to said base and thereby to each said vessel said orbital oscillation in a horizontal direction thereby imparting a principally horizontally circular main flow to material contained in the vessel;
- each said mixing means comprising at least one vertical tube-like element
- rigidly connected to and extending longitudinally within said vessel in a vertical direction away from the vessel bottom, and
- having in its bottom end region an inlet aperture opening to its interior tubular space above the vessel bottom and
- facing toward the direction from which said main flow approaches,
- whereby said element intercepts through said aperture a portion of the main flow to develop at least over the height of the element a separate spirally ascending flow discharging from the top of said element with circumferential scattering to be distributed at least in part over the surface of material in the vessel for mixing recirculation therewith;
- and
- a rapid finish mixing chamber
- disposed to receive material discharging from each of said two vessels and
- agitated to effect a quick final mixing and discharge of a finished molding composition.
An injection apparatus for injecting molding material into foundry mold flasks or core boxes comprising:
- an injection cylinder vessel
- resiliently mounted with its axis vertical and driven by means imparting to the cylinder an orbital motion of translation with its axis describing a closed path on an intersecting horizontal plane, thereby to develop an agitated flow of material in the vessel,
- said vessel having
- a hollow cylindrical body closed at top and bottom ends, a charging opening in its upper end through which molding materials are charged into the vessel, and an inlet for air under pressure in its upper part;
- an injection tube arranged in an upright position and extending within the vessel body from near the lower end thereof outwardly through the upper end thereof;
- a flexible elastic diaphragm below the air inlet and the charging opening, extending completely across the interior of the vessel body and below the lower end of the injection tube, providing the effective material containing interior surface of the body;
- said diaphragm being arranged to have sealing engagement with the lower end of the injection tube and spacing from the bottom end and cylindrical interior of the body when the region above the diaphragm is unpressurized;
- and
- an air outlet from the body space below the diaphragm.
