Abstract:
1. A blow molding station including a mold hanger for supporting a mold, the mold hanger having a vertical direction and a horizontal direction, the mold hanger comprising: a piston sleeve fully contained within the mold hanger and orthogonal to both the vertical direction and the horizontal direction; a piston sleeve head end having a size and shape, and capping the piston sleeve; a piston slideably engaged with and fully contained within the piston sleeve, the piston having a top conforming to the size and shape of the piston sleeve head end and a bottom; a moveable insert integral with the piston bottom and configured to be pushed by the piston bottom in an inward direction away from the piston sleeve head end into a mold supported by the mold hanger; and a first source of fluid pressure configured to apply pneumatic pressure to the piston top to push the piston slideably away from the piston sleeve head end and toward the mold, wherein the blow molding station is configured to use pressurized air from a pressurized air source to mold a bottle in the mold and the first source of fluid pressure applies pneumatic pressure from the pressurized air source; and wherein the piston top has an area larger than a cross sectional area of the moveable insert.
