An ejector control device for an injection molding machine performs a series of processes that move ejector pins forward and backward a plurality of times to remove a molded article from a mold. Each process has various elements, such as a starting condition, a delay time from satisfaction of the starting condition to actual start of the operation, a target position, and a movement speed with which the ejector pins advance (or retract) to the target position from the position reached in the previous process. Data are set to specify the elements of each process and the execution order of the processes.
