PROBLEM TO BE SOLVED: To provide an injection control device facilitating realization of an operation for optimization of molding conditions of a user, by so constituting an operational part executing a pressure limiting processing as to approximate to a fundamental requested operation of the user for an injection spindle. SOLUTION: The device is equipped with a first control means which is brought to a first control mode based on an injection pressure when the injection pressure works in a range not exceeding a first pressure limiting value and executes an injection speed control of the injection spindle based on a speed set value, a second control means which is brought to a second control mode based on the injection pressure when the pressure reaches the first pressure limiting value and executes the injection speed control of the injection spindle so that a target value of the injection pressure be the first pressure limiting value, and a third control means which is brought to a third control mode based on the injection pressure when the pressure reaches a second pressure limiting value higher than the first pressure limiting value and executes the injection speed control of the injection spindle so that a pressure detection value be lowered.
