Abstract:
1. A mold assembly for producing wall blocks comprising: a production pallet; a stripper shoe; a mold box having opposed side walls and opposed end walls which together form a perimeter of the mold box, the mold box having an open top and an open bottom, the production pallet enclosing the open bottom of the mold box during a block forming process; a feed drawer configured to move during the block forming process from a first position vertically offset from the mold box to a second position above the mold box and back to the first position and to discharge block forming material into the mold box during the block forming process; a material distribution element moveably connected to the feed drawer and configured to remove excess block forming material from the mold box or redistribute block forming material in the mold box as the feed drawer moves from the second position to the first position during the block forming process; a control member configured to control a path of travel of the material distribution element over the mold box as the feed drawer moves from the second position to the first position during the block forming process, a height of the material distribution element above the production pallet changing as the material distribution element moves along the path of travel during the block forming process; and a biasing member configured to continually apply a downward force on the material distribution element to bias the material distribution element against a top surface of the control member during a block forming process.
