I have to design a built in cabinet that on the lower portion has a tilt out door that houses a laundry bin mated to a chute in the floor. I have the general concept hashed out with the help of a cardboard mockup but I need to ask for some input on the best way to approach the lower hinge.

I was originally thinking of a couple of pins protruding from the face frame on either side that mate to slots milled into the tilt out door face, and then a hydraulic damper up top to ensure that the door opens smoothly. What do you think? Good approach or have you seen something better/easier?
