Method for forming concrete products
DCFirst Claim
1. A method for aligning a cement mold box in a concrete product forming machine, the mold box including a head assembly and a mold assembly, comprising:
- locating the head assembly in a predetermined alignment in relation to the mold assembly;
locking the head assembly and mold assembly together in the predetermined alignment;
mounting the locked head assembly to a vertically displaceable upper beam of the concrete product forming machine and mounting the locked mold assembly to a stationary frame of the concrete product forming machine;
unlocking the head assembly from the mold assembly while both the head assembly and the mold assembly remain locked to the concrete product forming machine; and
moving the head assembly with the upper beam and holding the mold assembly to the frame in the predetermined aligned position while forming concrete products with the concrete product forming machine.

Abstract
A mold box is flexibly mounted to a product forming machine having upper and lower vertically displaceable beams. A feed drawer dispenses concrete material into the mold box while a vibration system vertically vibrates the mold box while dampening horizontal vibration. The vibration system is driven by a single drive shaft that actuates first and second vibrator rods while at the same rotating a counter-weight in a counter-rotating direction. A set of alignment brackets lock the mold box into a predetermined aligned relationship while being mounted in the product forming machine. The bottom side of each mold box is mounted to the product forming machine in the same relative position to reduce machine readjustments. A set of telescoping legs hold the feed drawer assembly variable distances above the mold box. A unitized pallet feeder quickly moves pallets one at a time from an "on-deck" position to a "receiving" position underneath the mold box.

2. A method for aligning a cement mold box in a concrete product forming machine, the mold box including a head assembly and a mold assembly and the concrete product forming machine including a frame and an upper beam vertically displaceable in relation to the frame, the mold box mounted to the concrete product forming machine according to the following steps:
-
locating the head assembly in a predetermined lateral alignment in relation to the mold assembly; locking the head assembly and mold assembly together in the predetermined lateral alignment; rigidly coupling the mold assembly to a predefined location on the frame; lowering the upper beam down against the head assembly; rigidly coupling the head assembly to the upper beam; unlocking the head assembly from the mold assembly while both the head assembly and the mold assembly are coupled to the concrete product forming machine; and moving the upper beam vertically up and down on the frame while maintaining the predetermined lateral alignment between the head assembly and the mold assembly.
