摘要： An injection control method for an electrically-operated injection molding machine is provided, which is capable of sharply increasing the injection speed of a low-priced electric injection molding machine. A command pulse train is supplied to a servo circuit for an injection servomotor whereby substantial rotary motion of the injection servomotor is initially prevented, as a result of the fact that the torque limit value (Ts) is set at a value sufficient to establish equilibrium between the output torque of the injection servomotor and the resin pressure acting on the injection screw. The error between the target rotational position of the injection servomotor and an actual rotational position thereof then is allowed to increase until it reaches a feed stop positional error (Fs). The torque restriction is discontinued when the feed stop positional error Fs is reached, and a large drive current is caused to flow in the injection servomotor circuit in correspondence with the actual positional error which has now increased to the feed stop positional error Fs. Thus, the injection screw is initially driven by a great torque generated by the injection servomotor, so that the injection speed rises sharply.

摘要： A controller and a method for an ejector mechanism in an injection molding machine for appropriately setting a terminal position of a forward motion of ejector pins of the ejector mechanism. The terminal position of the forward motion is set to a position where an elastic force of return springs does not exceed a retaining force of a brake device for retaining the ejector pins at the terminal position. The elastic force of the springs are detected during the ejector pins are moved forward. A position of the ejector pins immediately before the detected elastic force of the springs exceeds the retaining force of the brake device is determined and displayed on a display device as a criterial position. The terminal position of the forward motion of the ejector pins is set not to exceed the determined criterial position.

摘要： An average is obtained between output readings of a pressure sensor obtained when forward and reverse thrusts are applied to an injection screw by positively driving a servomotor for injection. The average value is used as a correction value for a reading deviation of the pressure sensor. The injection servomotor is positively driven to apply a thrust to the screw. This known thrust and the actual reading of the sensor are compared. A deviation between these values is used as the correction value for the reading deviation of the sensor.

摘要： Clamping and injection operations are executed partially in parallel by adjusting a clamping speed and an injection start timing T so that sum .SIGMA.P of resin pressure acting on the parting plane of a mold cavity will not exceed mold clamping force F outputted at that time. An injection operation is started during the period in which the mold clamping force F is relatively low between mold touch and mold clamping completion, so that gas breathing from the mold cavity can be done easily without providing gas vent in the mold, thereby preventing resin filling failure or burning. Also, the clamping and injection operations are executed partially in parallel, so that time required for clamping and injection processes is shortened by time T' as a whole. Therefore, speeding of molding cycle can be attained.

摘要： A mold clamping control method capable of preventing any warp or strain on a molded product without stopping an injection pressure holding process so as to cancel the pressing force of an injection screw. In a series of injection and pressure holding processes, a movable platen is retracted from a mold clamping dwell position P2 to a mold opening dwell position P1, so that a substantial volume of a cavity of a mold is increased to temporarily lower the internal pressure of the cavity, thus making an internal stress of resin to be a product uniform to eliminate stress strains. In this method, an injection molding is performed to produce a precise product having no warp or strain even in molding a light guide plate which is subjected to molding abnormalities by the temporary stoppage of the injection pressure holding process according to the conventional method.

摘要： An ejector mechanism is driven by a servomotor. An ejector pin in the ejector mechanism is made to perform a motion such that the ejector pin reaches a predetermined protrusion limit position beyond a position where the removal of a molded product from a cavity or core is completed after making a check for positioning, and a plurality of cycles of reciprocating motion of a short amplitude such that the ejector pin neither retracts beyond a position where the removal of the molded product from the cavity or core is started nor protrudes to the protrusion limit position, without requiring a check for positioning.

摘要： A method and an apparatus for automatic zero adjustment of an injection-molding machine, in which an axis driven by a servomotor can be automatically returned to its origin with accuracy and speed. When a one-revolution signal is produced after the axis reaches a deceleration position, a preset coordinate position of a reference point is written in a current-value register. Subsequently, when the axis driven toward an absolute position reaches the absolute position, the preset coordinate position of the reference point is corrected with use of a correction value calculated on the basis of a known coordinate position of the absolute position and the register value. When the axis driven toward the reference point reaches the corrected position, the preset reference point coordinate position is written in the current-value register.
