Abstract
A release agent spray method and apparatus for a die casting machine. As a movable die plate is moved in a die closing direction, a spray head is moved in a perpendicular direction to a spray position. The movable die plate is stopped when it has reached a position at which the distance between the spray head and a die cavity surface of a movable die and the distance between the spray head and die cavity surface of a fixed die both become equal to a spray distance. A release agent is sprayed from the spray head onto the cavity surfaces of the movable die and the fixed die.
