摘要： An ejector control device for an injection molding machine performs a series of processes that move ejector pins forward and backward a plurality of times to remove a molded article from a mold. Each process has various elements, such as a starting condition, a delay time from satisfaction of the starting condition to actual start of the operation, a target position, and a movement speed with which the ejector pins advance (or retract) to the target position from the position reached in the previous process. Data are set to specify the elements of each process and the execution order of the processes.

摘要： A crosshead position Cf for obtaining a set mold clamping force is obtained based on a mold touch position Ct obtained in mold clamping process in immediately preceding molding cycle, and a crosshead is allowed to move to the position Cf. During that time, it is determined whether a load La of a servomotor for mold clamping operation which drives a toggle mechanism exceeds a judgment load Ls, and a crosshead position Ca when the load La exceeds the judgment load Ls is stored as a mold touch position. In the next molding cycle, a crosshead position Cf where the set mold clamping force is obtained is obtained based on this stored mold touch position.

摘要： A controller for an injection molding machine capable of reducing an extension of a cycle time in a screw retreat process after the end of measurement, obtaining a more accurate and uniform measured resin amount, and determining measurement conditions in a short period of time. After the measurement is finished, the screw is stopped from rotating and retreated at a first speed V1. The screw is reversely rotated at a predetermined speed Rv in a set zone. As this is done, the screw is retreated at a second speed V2 lower than the first speed V1. After the reverse rotation zone is terminated, the screw is stopped from rotating and retreated at a third speed V3 to a set retreat stop position. By doing this, the cycle time can be made shorter than in the case where the retreat and reverse rotation of the screw are performed separately. Since the retreating speed of the screw is low while the screw is being reversely rotated, a sudden pressure change can be suppressed, so that precise measurement can be made. Since conditions for the reverse rotation and retreat of the screw can be regulated independently, they can be adjusted to optimum conditions in a short period of time.

摘要： A screw is rotated at a set speed and retreated by performing back pressure control for keeping a resin pressure at a set pressure. When the retreat position of the screw reaches a change point set nearby a set metering completion position, the back pressure control for keeping the resin pressure at a set resin pressure is stopped. A command for positioning the screw at a metering completion position is output to position the screw at the metering completion position. At the same time, when a screw position reaches the change point, the screw is reversed by a set value at a set speed.

摘要： A method of and an apparatus for precisely determining a separating force of a molded product from a mold by an ejector in an injection molding machine. A load exerted on an ejector mechanism in operation without a product molded in the mold is constituted by an inner resistance of the ejector mechanism. The inner resistance includes frictional force produced within the ejector mechanism and resilient forces of springs for returning ejector pins to retracted positions thereof. On the other hand, the load exerted on the ejector mechanism in operation with a product molded in the mold is constituted by the inner resistance and the separating force of the molded product from the mold. Thus, a difference between the loads detected in driving the ejector mechanism with and without a molded product at each ejector position precisely represents the separating force of the molded product from the mold. Judgment on defectiveness/non-defectiveness of the molded product, and abnormality of the injection molding operation and the ejector mechanism are performed more precisely based on the determined separating force of the molded product.

摘要： There is provided the torque limiter for limiting a torque command to be output when pressure feedback control of the pressure holding step is performed. After the start of the pressure holding step, the torque limiter limits output torque of the servomotor for injection for a predetermined time period after the screw starts to move backward. As a result, the output torque in the backward direction of the screw is limited and reduced, whereby the speed of backward movement of the screw is reduced, and decrease of the pressure applied to the resin becomes moderate, thus abrupt drop of the pressure can be avoided.

摘要： An injection screw position Xa, injection speed Va, and injection pressure Pa are read. A deceleration distance D the injection screw moves from the point where the injection operation has been stopped at the current moment to be decelerated by maximum deceleration till the point where the injection speed is reduced to zero is determined from a corrected deceleration in which the amount of correction α is added to a predetermined deceleration A inherent in the machine and the read injection speed Va. The determined deceleration distance D is multiplied by the amount of change in injection pressure with respect to the amount of change in the injection screw position to determine a predicted increment in pressure (D·ΔP/ΔX). The predicted increment in pressure is added to the current injection pressure Pa to determine an injection pressure Pa* predicted when the screw is suddenly decelerated at the current moment. If the predicted injection pressure Pa* exceeds the predetermined limit pressure Pmax, the injection operation is stopped to decelerate the screw.

摘要： A controller of injection molding machine capable of stabilizing a peak pressure of resin appearing when an injection process is switched to a pressure-holding process, by reducing the variation of the peak pressure. Resin pressure Pr is detected at every predetermined sampling period Δt. There is a time lag between the time at which the resin pressure reaches an injection/pressure-holding switch determining resin pressure P(v−p) and the sampling time t2 at which the resin pressure that has reached the value P(v−P) is detected. Hence, a difference Ve between the detected resin pressure value Pr′ and the switch determining resin pressure P(v−p) is obtained. The transition time period T in which pressure should be changed from a pressure-holding start pressure Ps to a pressure-holding pressure Pp is corrected by T=T0−α×Ve to make the transition time period T shorter when the difference Ve is greater, to thereby hold down the peak pressure Pmax. By this, the variation ΔPmax of the peak pressure Pmax is reduced. Since the pressure is kept uniform, the quality of a molded produce improves.
