An injection-molded door liner for a refrigerator door is provided. The door liner is injection molded as a single, integral piece and defines an icebox compartment, an upper hinge assembly, and a lower hinge assembly. An icebox door is rotatably mounted to the upper and lower hinge assembly to insulate the icebox compartment from the fresh food chamber. In this manner, the icebox compartment and the icebox door define a sealed chamber for receiving chilled air from a sealed cooling system.

1. An injection molded door liner for a door of a refrigerator appliance, the refrigerator appliance defining a vertical direction, the door liner comprising: an icebox compartment having a back wall and a plurality of sidewalls;an upper hinge assembly comprising an upper bracket extending from the icebox compartment, an upper hinge pin extending from the upper bracket downward along the vertical direction, and a first keyed feature extending from the upper bracket downward along the vertical direction;a lower hinge assembly comprising a lower bracket extending from the icebox compartment and a lower hinge pin extending from the lower bracket upward along the vertical direction;an icebox door rotatably mounted to the icebox compartment by the upper hinge assembly and the lower hinge assembly, the icebox door defining a second keyed feature and being attachable or detachable from the icebox compartment only when the icebox door is positioned at a selected angle relative to the icebox compartment such that the first keyed feature and the second keyed feature are aligned and the first keyed feature may be disposed within the second keyed feature, or vice versa; anda guide wall extending from the upper bracket downward along the vertical direction, the guide wall being positioned adjacent to the first keyed feature and extending along the selected angle,wherein the icebox compartment and at least one of the upper hinge assembly and the lower hinge assembly are injection molded as a single, integral part;the icebox door is configured to be movable to a lifted position relative to the upper and lower hinge assemblies, the lifted position defined by the first keyed feature aligned with and disposed in the second keyed feature, or vice versa, so that a lower hinge recess of the icebox door is vertically separated from the lower hinge pin to allow the icebox door to detach from the icebox compartment; andthe icebox door is configured to be vertically movable from the lifted position to an assembled position, the assembled position defined by the first keyed feature and second keyed feature vertically separated such that the lower hinge pin is received in the lower hinge recess to allow the icebox door to rotate. 2. The injection molded door liner of claim 1, wherein the icebox compartment, the upper hinge assembly, and the lower hinge assembly are injection molded as a single, integral part. 3. The injection molded door liner of claim 2, wherein the upper hinge pin is longer than the lower hinge pin. 4. The injection molded door liner of claim 2, wherein the first keyed feature is a keyed boss extending from the upper hinge bracket and the second keyed feature is a keyed recess defined within the icebox door. 5. The injection molded door liner of claim 2, wherein the selected angle is between 0 and 150 degrees. 6. The injection molded door liner of claim 2, wherein the selected angle is 30 degrees. 7. The injection molded door liner of claim 2, wherein the lower hinge bracket defines an alignment recess, the alignment recess being configured to receive a lower lip of the icebox door when the icebox door is positioned at the selected angle relative to the icebox compartment. 8. The injection molded door liner of claim 2, wherein the icebox door rests on the lower hinge bracket in the assembled position, the first keyed feature and the second keyed feature being separated in the assembled position to allow rotation of the icebox door. 9. The injection molded door liner of claim 1, wherein the door liner is between about 1/16 inch and 3/16 inch thick. 10. The injection molded door liner of claim 1, wherein the guide wall protrudes from the upper hinge bracket farther than the first keyed feature, but not as far as the upper hinge pin. 11. A refrigerator appliance defining a vertical direction and comprising: a cabinet including a liner defining a chilled chamber;a door configured to provide access into the chilled chamber;a door liner that is injection molded as a single, integral piece and mounted in the door, the door liner defining a sub-compartment, the sub-compartment comprising: an icebox frame;an upper hinge assembly comprising an upper bracket extending from the icebox frame and an upper hinge pin extending from the upper bracket downward along the vertical direction, and a first keyed feature extending from the upper bracket downward along the vertical direction;a lower hinge assembly comprising a lower bracket extending from the icebox frame and a lower hinge pin extending from the lower bracket upward along the vertical direction; andan icebox door defining an upper hinge recess and a lower hinge recess configured to receive the upper hinge pin and the lower hinge pin, respectively, such that the icebox door is rotatably mounted to the icebox frame by the upper hinge assembly and the lower hinge assembly about a hinge axis, the icebox door defining a second keyed feature and being attachable or detachable from the icebox frame only when the icebox door is positioned at a selected angle relative to the icebox frame such that the first keyed feature and the second keyed feature are aligned and the first keyed feature may be disposed within the second keyed feature, or vice versa;wherein the icebox door is configured to be movable to a lifted position relative to the upper hinge assembly, the lifted position defined by the first keyed feature aligned with and received in the second keyed feature so that a lower hinge recess of the icebox door is vertically separated from the lower hinge pin to allow the icebox door to detach from the icebox compartment; andthe icebox door is configured to be vertically movable from the lifted position to an assembled position, the assembled position defined by the first keyed feature and second keyed feature vertically separated such that the lower hinge pin is received in the lower hinge recess to allow the icebox door to rotate about the hinge axis. 12. The refrigerator appliance of claim 11, wherein the upper hinge pin is longer than the lower hinge pin. 13. The refrigerator appliance of claim 12, wherein the upper hinge bracket defines a keyed boss and the icebox door defines a keyed recess, the icebox door being attachable or detachable from the icebox frame only when the keyed boss is received within the keyed recess. 14. The refrigerator appliance of claim 13, wherein the keyed boss is receivable within the keyed recess when the icebox door is positioned at a selected angle relative to the icebox frame. 15. The refrigerator appliance of claim 14, wherein the selected angle is 30 degrees. 16. The refrigerator appliance of claim 14, wherein the upper hinge bracket defines a guide wall disposed at the selected angle, the guide wall configured to assist in rotating the icebox door to the selected angle. 17. The injection molded door liner of claim 16, wherein the guide wall protrudes from the upper hinge bracket farther than the first keyed feature, but not as far as the upper hinge pin. 18. The refrigerator appliance of claim 14, wherein the lower hinge bracket defines an alignment recess, the alignment recess being configured to receive a lower lip of the door when the icebox door is positioned at the selected angle relative to the icebox frame. 19. The refrigerator appliance of claim 13, wherein the icebox door rests on the lower hinge bracket in an assembled position, the keyed boss and the keyed recess being separated in the assembled position to allow rotation of the icebox door about the hinge axis.
