Abstract
A mold assembly including a plurality of mold components configured to form a mold cavity having a desired shape, at least one of the mold components having a notch configured to form a set-back flange in a masonry block formed in the mold cavity, the notch having a depth. The mold assembly further includes a moveable flange plate and a drive assembly configured to extend the moveable flange plate into and retract the moveable flange plate from the notch within a desired range of distances so as to adjust the depth of the notch.
Claims23
A mold assembly, comprising:
- a plurality of mold components configured to form a mold cavity having a desired shape, at least one of the mold components having a notch configured to form a set-back flange in a masonry block formed in the mold cavity, the notch having a depth;
- a moveable flange plate;
- and
- a drive assembly configured to extend the moveable flange plate into and retract the moveable flange plate from the notch within a desired range of distances so as to adjust the depth of the notch.
A mold assembly, comprising:
- a plurality of liner plates configured to form a mold cavity having a desired shape;
- a head shoe assembly configured to be positioned at least partially within the mold cavity and having a notch configured to form a set-back flange in a masonry block formed in the mold cavity, the notch having a depth;
- a moveable flange plate;
- and
- a drive assembly configured to extend the moveable flange plate into and retract the moveable flange plate from the notch within a desired range of distances so as to adjust the depth of the notch.
A mold assembly, comprising:
- a plurality of liner plates configured to form a mold cavity having a desired shape, wherein at least one liner plate having a notch configured to form a set-back flange in a masonry block formed in the mold cavity, the notch having a depth;
- a moveable flange plate;
- and
- a drive assembly configured to extend the moveable flange plate into and retract the moveable flange plate from the notch within a desired range of distances so as to adjust the depth of the notch.
A method of molding a masonry block in a mold cavity of a mold assembly formed by a plurality of mold components, at least one mold component having a notch having a depth;
- the method comprising:
- adjusting the depth of the notch;
- filling the mold cavity with dry cast concrete;
- compacting the dry cast concrete to form a pre-cured masonry block with a set-back flange formed by the notch extending from a lower face of pre-cured masonry block along an edge shared with a rear face.
A mold assembly, comprising:
- a plurality of mold components configured to form a mold cavity having a desired shape, at least one of the mold components having a notch configured to form a set-back flange in a masonry block formed in the mold cavity, the notch having a depth;
- and
- a flange assembly configured to selective adjust the depth of the notch.
A block structure comprising a plurality of masonry block formed by a common mold assembly, each block having a set-back flange having a depth which is different from a depth of a set back flange of at least one other masonry block of the plurality of masonry blocks.
