Housing case, method for manufacturing housing case, and glass insert molding die used in same

A glass insert molding die comprising a stationary die and a movable die that sandwich a flat plate primarily comprising a glass plate when the dies are closed, and form a cavity that faces a periphery of the flat plate facing the stationary die and also an end surface of the flat plate, wherein

• the stationary die includes a sliding core having a bottom portion that comes into contact with the periphery of the flat plate facing the stationary die and a wall portion that is connected to the bottom portion and positionably comes into contact with the end surface of the flat plate, the bottom portion and the wall portion provided at the front end of the sliding core, and
• a suction hole provided in the surface where the flat plate is sandwiched;
• and
• the sliding core is capable of being advanced and retracted in a die-closing direction between a flat plate positioning position and a cavity forming position, the flat plate positioning position being the position where the front-end bottom portion does not protrude from the surface of the stationary die where the flat plate is sandwiched but the front-end wall portion comes into contact with the flat plate, and the cavity forming position being the position where the front-end bottom portion and the front-end wall portion are separated from the flat plate.
