Sweep assembly for a refrigerator icemaker

A refrigerator appliance defining a vertical direction, a lateral direction, and a transverse direction, comprising:

• a cabinet defining a chilled chamber;
• a door being rotatably mounted to the cabinet to provide selective access to the chilled chamber;
• an icebox mounted to the door and defining an ice making chamber;
• and
• an ice making assembly positioned within the ice making chamber, the ice making assembly comprising:
• a resilient mold defining a mold cavity for receiving water;
• a mold frame for supporting the resilient mold, the mold frame being rotatable between a first position and a second position;
• a heat exchanger in thermal communication with the resilient mold to freeze the water and form one or more ice cubes;
• a lifter mechanism positioned adjacent to the resilient mold and rotatable with the mold frame between the first position and the second position, the lifter mechanism configured to deform the resilient mold as the mold frame rotates between the first position and the second position;
• and
• a sweep assembly to facilitate extraction of the one or more ice cubes from the resilient mold, the sweep assembly comprising:
• a sweep blade slidably mounted to the mold frame over the resilient mold and being movable between a first position and a second position;
• a mechanical stop that moves the sweep blade toward the second position as the lifter mechanism moves toward the second position;
• and
• one or more rollers rotatably mounted to the sweep blade for engaging the mechanical stop as the lifter mechanism moves toward the second position.
