Concrete mold form

A mold form for forming a molded product, comprising:

• a first side form;
• a plurality of parallel tracks;
• a plurality of carriages, each carriage movable along a track, the first side form being supported on the carriages, each carriage having at least one wheel engaging the track and at least one of the carriages having a drive wheel;
• a hydraulic motor to rotate the drive wheel on the at least one of the carriages to move the carriages and first side form along the tracks between a first, molding position to a second, release position, hydraulic lines being mounted along the first side form to power the hydraulic motor and, further comprising a cart mounting a hydraulic pump separate from the first side form to power the hydraulic motor.

A mold form for forming a molded product, comprising:

• a first side form including a plurality of sections;
• a plurality of parallel tracks;
• a plurality of carriages mounted to the first side form for movement with the first side form, each carriage movable along a track, the first side form being supported on the carriages, each carriage having at least one wheel engaging the track, at least one of said plurality of carriages supporting each of said plurality of sections;
• selected ones of said carriages each having a hydraulic motor and a drive wheel driven by the hydraulic motor, said drive wheels engaging the track on which the selected ones of said carriages is movable;
• hydraulic lines mounted on the first side form and connected to the hydraulic motors in each of the selected ones of said carriages to simultaneously power the hydraulic motors to rotate the drive wheels to simultaneously move the carriages and first side form along the tracks between a first, molding position to a second, release position, the hydraulic motors moving the side form away from the molded product after the molded product has cured to allow removal of the molded product from the mold form,
• wherein said selected ones of said carriages further includes a spring guide mounted within the selected ones of said carriages, a spring supported within the spring guide, a wheel bracket pivotally mounted to the selected ones of said carriages and supporting the drive wheel for rotation, a first spring seat at a first end of the spring, a second spring seat at a second end of the spring, a spring stop at an end of the spring guide engaging the first spring seat and a contact bar engaging the second spring seat and the wheel bracket, the spring acting between the spring stop and the contact bar to pivot the wheel bracket to force the drive wheel into engagement with the track.
