Abstract
A mold frame includes a bottom frame, a side frame and at least one position-limiting structure. The bottom frame has an opening. The side frame is disposed on a periphery of the bottom frame. The at least one position-limiting structure is disposed on a first inner side wall of the side frame. The position-limiting structure has a first side wall that is in direct contact with the first inner side wall of the side frame, and a second side wall opposite to the first side wall. The second side wall includes two surfaces that are arranged along a thickness direction of the bottom frame, and the two surfaces are connected. At least one of the two surfaces is inclined with respect to the first side wall, and a first angle, facing the first side wall, between two planes where the two surfaces are located is an obtuse angle.
