Abstract
A mold assembly for manufacturing concrete blocks that is adapted for use in a concrete block machine. The mold assembly includes a plurality of liner plates, each having a major surface, the liner plates configured such that the major surfaces form a mold cavity having a desired form, and wherein at least one of the liner plates is moveable. A gear drive assembly is selectively coupled to the at least one moveable liner plate and configured to move the at least one moveable liner plate toward and away from an interior of the mold cavity. A stabilizer assembly is operatively coupled to the gear drive assembly and is configured to support the gear drive assembly as it moves the at least one moveable liner plate.

A mold assembly for manufacturing concrete blocks and adapted for use in a concrete block machine, the mold assembly comprising:
- a plurality of liner plates, each having a major surface, the liner plates configured such that the major surfaces form a mold cavity having a desired form, wherein at least one of the liner plates is moveable between a retracted position and a desired extended position toward an interior of the mold cavity;
- a gear drive assembly including:
- a first element selectively coupled to the at least one moveable liner plate;
- and
- an actuator operatively coupled to the first element and configured to push the at least one moveable liner plate in a first direction toward the extended position via the first element by moving and applying a force in a second direction which is different from the first direction and configured to pull the at least one moveable liner plate from the extended position toward the retracted position via the first element by moving and applying a force in a direction which is opposite to the second direction;
- and
- a stabilizer assembly operatively coupled to the actuator and configured to support the actuator as it moves and applies the force in the second direction and moves and applies the force in the direction opposite the second direction.
A mold assembly for manufacturing concrete blocks and adapted for use in a concrete block machine, the mold assembly comprising:
- a plurality of liner plates, each having a major surface, the liner plates configured such that the major surfaces form a mold cavity having a desired form, wherein at least one of the liner plates is moveable;
- a gear drive assembly selectively coupled to the at least one moveable liner plate and configured to move the at least one moveable liner plate toward and away from an interior of the mold cavity;
- and
- a stabilizer assembly operatively coupled to the gear drive assembly and configured to support the gear drive assembly as it moves the at least one moveable liner plate, wherein the stabilizer assembly further comprises:
- at least one linear bearing block having a linear bearing track;
- and
- a guide rail selectively coupled to the gear drive assembly and configured to slideably interlock with and to travel along the linear bearing track.
A mold assembly for manufacturing concrete blocks and adapted for use in a concrete block machine, the mold assembly comprising:
- a plurality of side liner plates, each having a major surface, the side liner plates configured to be moveable so as to form at least a portion of one or more mold cavities, wherein the major surface of each side liner plate forms a side of a corresponding mold cavity;
- a gear drive system selectively coupled to each side liner plate and configured to move each side liner plate toward and away from an interior of the corresponding mold cavity;
- and
- a control system including a controller configured to receive a plurality of status signals representative of operations of the concrete block machine and to coordinate movement of each side liner plate with operations of the concrete block machine by controlling the gear drive assembly based on the status signals.
A mold assembly for manufacturing concrete blocks and adapted for use in a concrete block machine, the mold assembly comprising:
- a plurality of liner plates, each having a major surface, the liner plates configured such that the major surfaces form a mold cavity having a desired form, wherein at least one of the liner plates is moveable;
- a gear drive assembly selectively coupled to the at least one moveable liner plate and configured to move the liner plate in a first direction toward an interior of the mold cavity by applying a force in a second direction different from the first direction, and to move the liner plate opposite the first direction by applying a force in a direction opposite the second direction;
- and
- a control system including a controller configured to receive a plurality of status signals representative of operations of the concrete block machine and to coordinate movement of the at least one moveable liner plate with operations of the concrete block machine by controlling application of the forces by the gear drive assembly based on the status signals.
A mold assembly for manufacturing concrete blocks and adapted for use in a concrete block machine, the mold assembly comprising:
- a plurality of side liner plates, each having a major surface, the side liner plates configured to be moveable so as to form at least a portion of one or more mold cavities, wherein the major surface of each side liner plate forms a side of a corresponding mold cavity;
- a gear drive system selectively coupled to each side liner plate and configured to move each side liner plate toward and away from an interior of the corresponding mold cavity;
- a pressurization system configured to maintain the gear drive system at a positive air pressure relative to air pressure of at least the one or more mold cavities such that air will flow generally away from the gear drive system toward the at least one or more mold cavities.
A mold assembly for manufacturing concrete blocks and adapted for use in a concrete block machine, the mold assembly comprising:
- a plurality of side liner plates, each having a major surface, the side liner plates configured to be moveable between a retracted position and an extended position so as to form at least a portion of one or more mold cavities, wherein the major surface of each side liner plate forms a side of a corresponding mold cavity;
- a gear drive system selectively coupled to each side liner plate and configured to push each side liner plate in a first direction toward the extended position by applying a force in a second direction which is different from the first direction and to pull each side liner plate away from an interior of the corresponding mold cavity toward the retracted position by applying a force in a direction which is opposite the first direction;
- and
- a plurality of heater elements, each selectively coupled to one of the moveable liner plates and configured to maintain the corresponding moveable liner plate at a desired temperature.
A mold assembly for manufacturing concrete blocks and adapted for use in a concrete block machine, the mold assembly comprising:
- a plurality of moveable side liner plates, each configured to form a side of a corresponding mold cavity;
- a control element selectively coupled to each moveable side liner plate;
- and
- an actuator selectively coupled to the control element and configured to move the control element in first direction to cause the control element to push each moveable side liner plate to move in a direction toward an interior of the corresponding mold cavity, wherein the first direction is different from the direction toward the interior of the corresponding mold cavity of each moveable side liner plates, and configured to move the control element in a second direction which is opposite the first direction to cause the control element to pull each moveable side liner plate in a direction away from the interior of the corresponding mold cavity.
