Abstract
A sand molding apparatus and method, whereby cope and drag portions of a sand mold are formed simultaneously via pressurized sand delivered to each side of a pattern in a perpendicular trajectory. Two opposing sand shooting passageways include a vertical inner side wall and a horizontal inner side wall extending at an angle from the vertical inner side wall. A sand shooting plate at the outlet of each sand shooting passageway includes removable and interchangeable port and cover inserts that can be arranged in custom arrays within the sand shooting plate.
Claims20
A sand casting apparatus for forming a sand mold about a pattern, comprising:
- at least one angled sand shooting passageway including and extending between an inlet and an outlet, wherein the outlet is above and/or below the pattern;
- a sand shooting plate in combination with the outlet, wherein the sand shooting plate comprises a plurality of openings;
- and
- a plurality of interchangeable inserts disposable over the plurality of openings, the plurality of interchangeable inserts including sand shooting port inserts and cover plate inserts, wherein each of the inserts is manually placeable and replaceable over one of the openings to control an opening and closing of the sand shooting plate.
A sand casting apparatus for forming a sand mold about a pattern, comprising:
- at least one sand shooting passageway including and extending between an inlet and an outlet, wherein the outlet is above and/or below the pattern;
- a sand shooting plate in combination with the outlet;
- a passageway body enclosing the passageway, the passageway body including a vertical inner side wall and a horizontal inner side wall extending at an angle from the vertical inner side wall toward the inlet;
- and
- an internal tilted arc plate within the passageway and extending between the vertical inner side wall and a horizontal inner side wall, wherein the tilted arc plate has a first end abutting an outer edge of the horizontal inner side wall at the inlet, and a second end including a fixing plate embedded in the vertical inner side wall.
A sand casting apparatus for forming a sand mold about a pattern, comprising:
- at least one sand shooting passageway including and extending between an inlet and an outlet, wherein the outlet is above and/or below the pattern;
- and
- a sand shooting plate in combination with the outlet, wherein the sand shooting plate comprises an upper sand shooting plate body over a lower sand shooting plate body, the upper shooting plate body comprises a plurality of sand shooting ports arranged in an array, and further comprising a groove seat between the upper sand shooting plate body and the lower sand shooting plate body.
