摘要： An injection unit including a heating barrel and an injection screw rotationally and axially movable and placed in the heating barrel is disposed on one side of a clamping mechanism for clamping a mold. The injection screw is driven and controlled for operation through a ball screw by an electric motor. Products, each of a moving speed of the ball screw and an operating current supplied to the electric motor in a unit time, are accumulated to calculate a total energy value indicating the amount of total energy supplied to the ball screw. A life energy value is predetermined on the basis of products, each of force generated by the ball screw and a moving speed of the ball screw. It is decided that a life of the ball screw has terminated when the total energy value A is equal to or greater than the life energy B (A≧B).

摘要： An injection speed control procedure is applied to controlling an injection screw included in an electric injection molding machine and driven by an electric motor. An injection process is divided into a plurality of injection stages. Injection speed at which the injection screw is moved is changed at a time point when a value PS obtained by integrating injection pressure with respect to the position of the injection screw or a value PT obtained by integrating injection pressure with respect to injection time coincides with a predetermined reference value determined for each injection stage.
