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.

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： In an injection molding machine combined with a peripheral apparatus, control units capable of interchanging signals are provided for the molding machine and the peripheral apparatus. Each control unit comprises a memory device storing set molding data applied with numbers or identifications. When the control unit of the molding machine sends the set data number or identification to the control unit of the peripheral apparatus to read out from the memory devices, the set molding data are formed when the numbers or identifications coincide with each other.
