1. A mold frame, comprising:
a bottom frame having an opening;
a side frame disposed on a periphery of the bottom frame;
at least one position-limiting structure disposed on a first inner side wall of the side frame; and
fixing members each of which is connected to the side frame and/or the bottom frame, the fixing members being configured to fix the mold frame, wherein
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; and
each fixing member includes:
a first support plate including:
a horizontal portion parallel to a first surface of the bottom frame directly connected to the first inner side wall, one end of the horizontal portion is connected to a corresponding outer side wall of the side frame, and an opposite end of the horizontal portion is connected to a vertical portion; and
the vertical portion extending along the thickness direction of the bottom frame; and
a second support plate connected to a second surface of the bottom frame opposite to the first surface of the bottom frame, and extending along the thickness direction of the bottom frame, so that the fixing member, the side frame and the bottom frame constitute a U-shaped structure.
