    摘要: An essentially tubular shell has movable tops and bottoms, which are subjected to vibratory impacts in non-cyclically recurring pulses; top or bottom may be subjected to a constant pressure, or both may be subjected to impacts which are synchronized and opposite each other. The impact pulses are controllable both as to frequency (which may be zero), amplitude and wave shape, the impulses being preferably controlled from an electrical programming source which controls application of pressure fluid to the top and bottom.

    摘要: Foundry sand molding apparatus for simultaneously forming cope and drag molds. The cope and drag molds are substantially simultaneously pre-jolted and jolt-squeezed to assure uniform density in the molds. Thereafter the apparatus laterally transfers the cope and drag molds into vertical alignment at an assembly station, with the drag mold being inverted and lowered during lateral transfer of same.

    摘要: A support table for foundry sand molding machines is elevated from a lowermost position to a sand supply position wherein sand is fed into a flask supported on the table. The table is then moved downwardly to a predetermined position slightly above the lowermost position while being vibrated to compact the sand. The table is then elevated to an upper position for squeezing the sand against a squeeze board carried by a head on the machine.

    摘要: Foundry sand molding apparatus includes a head and table between which sand molds are squeezed. The head is rotatably indexable about a horizontal axis above the table, and carries different cope and drag squeeze boards selectively alignable with the table for producing different cope and drag sand molds on the same apparatus. The head has a sand supply passage therethrough and is rotatably indexable to a sand supply position with the passage vertically aligned with the table for supplying sand therethrough to a flask supported on the table. The head is rotatable in either of opposite directions from its sand supply position for selectively aligning either the cope or drag squeeze board with the table. Baffles extending across the sand supply passage perpendicular to one another are individually adjustable for adjusting the distribution of sand supplied through the passage. Pneumatically operated vibrators are associated with each squeeze board, and position responsive valve means is responsive to the position of the head for supplying air only to the vibrator associated with the squeeze board aligned with the table.
