When the deceleration start point is reached, the meter-in side of the hydraulic driving actuator is subjected to a flow rate control to thereby start the deceleration control processing. The position to which the movable unit is moved is detected to use a speed instruction corresponding to the movement position to subject the hydraulic driving actuator to a meter-in control. The position to which the movable unit is moved is detected to calculate the moving speed of the movable unit. Based on the speed instruction, the moving speed is subjected to the feedback control using the meter-out control to the hydraulic driving actuator.

The method (400) comprises: during a second portion of the mold opening cycle of the injection mold (100), the second portion occurring later in time relative to a first portion of the mold opening cycle of the injection mold (100): controlling velocity of at least one of: (i) the moveable mold half (102, 502) relative to the stationary mold half (104, 504), (ii) the ejector (230) relative to the moveable mold half (102, 502); and (iii) an ejector actuator linked to the core insert (112, 114, 512, 514); and (iv) a stripper actuator that is linked to the stripper sleeve (116, 516); the controlling executed such that the molded article (310, 312, 506) is ejected from the molding component with a substantially zero departure-velocity along the first axis of operation.

A pressure controller for an injection molding machine capable of reducing variations of pressure in a mold in molding cycles and providing molded articles of stable quality is provided. The pressure controller includes an in-mold pressure estimation unit for estimating a pressure in the mold based on an injection pressure detected with an injection pressure detection unit, and an amount of movement of a screw detected with a screw movement amount detection unit, and an in-mold pressure control unit for controlling such that the estimated in-mold pressure becomes a set in-mold pressure after the pressure control is performed in a dwell step with an injection pressure control unit.

An injection molding machine includes a cylinder that accommodates a molten resin, a discharging nozzle, a piston that discharges the molten resin from the discharging nozzle, and one or more processors configured to execute the following functions. The functions include calculating a target pressure at which a flow rate of the molten resin discharged from the discharging nozzle becomes an indicated flow rate, controlling a pressure of the molten resin in the cylinder such that the pressure becomes the target pressure, acquiring a temperature of the molten resin in the cylinder, and acquiring a pseudo-plastic viscosity corresponding to the temperature of the molten resin. The target pressure is calculated based on the indicated flow rate, the temperature of the molten resin, the pseudo-plastic viscosity, and the size of the discharging nozzle.

An injection molding machine uses a controller to effectively control its operation. The controller may determine and/or receive information regarding the machine's maximum load capacity, and may also determine a current operational load value of the machine. The controller may cause the machine to operate at any number of combinations of settings of operational parameters which result in the machine operating at or below the maximum load value by adjusting any number of machine parameters associated with the injection molding machine based on feedback sensors measuring real-time operating conditions of the machine.
