Injection molding system and method for manufacturing molded object

An injection molding system comprising:

• an injection molding machine configured to inject a molten material into a mold to mold a molded object;
• a tray moving unit configured to move a plurality of trays along a first direction and along a second direction intersecting the first direction in a work area from a discharge position, via a placement position, to the discharge position, the discharge position being a position where the molded object is taken out of the work area;
• a robot configured to place the molded object on a tray moved to the placement position among the plurality of trays;
• and
• a housing in which at least the tray moving unit is disposed, wherein
• the tray moving unit moves a first tray from the discharge position to the placement position, and moves the first tray from the placement position to the discharge position after the molded object is placed by the robot on the first tray in the placement position, and moves a second tray on which the molded object is not yet placed by the robot, from the discharge position to the placement position while the first tray is moved from the placement position to the discharge position,
• the tray moving unit includes a discharging mechanism configured to switch between a protruded state in which the discharging mechanism protrudes from the housing towards an outside of the housing and a stowed state in which the discharging mechanism is accommodated inside the housing, and
• the discharging mechanism defines the discharge position when the discharging mechanism is in the protruded state.
