Injection molding system

An injection molding system comprising:

• a first unit that includes a first injection molding machine configured to inject a first molding material into a first cavity partitioned by a first fixed mold and a movable mold;
• a second unit that includes a second injection molding machine configured to inject a second molding material into a second cavity partitioned by a second fixed mold and the movable mold;
• and
• a movement mechanism configured to, after the first molding material is injected into the first cavity, move the movable mold filled with the first molding material from the first injection molding machine to the second injection molding machine, the movement mechanism including:
• a first robot configured to take the movable mold from the first injection molding machine;
• a slider on which the first robot places the movable mold when the slider is located at a first position, the slider being configured to move the movable mold from the first position directly adjacent to the first injection molding machine to a second position directly adjacent to the second injection molding machine;
• and
• a second robot configured to grip the movable mold from the slider when the slider is located at the second position and place the movable mold in the second injection molding machine,
• wherein a heater is placed at the slider, and
• the heater is configured to adjust a temperature of the movable mold while the movable mold moves from the first position to the second position on the slider.
