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： An excessive load detection device for an injection molding machine capable of detecting an excessive load exerted on the injection screw when the screw is driven with resin remaining unmolten in the heating cylinder. An output torque of the servomotor for axially moving the screw is limited to a predetermined value by a torque limiter and the screw is driven to move forward in a direction of injection by a predetermined amount at a predetermined velocity. If reference time elapses before the axial motion of the set amount is completed or a position deviation exceeds a reference value, it is determined that the remaining resin has low fluidity to cause an excessive load on the screw and an alarm is issued. When the axial motion of the screw is completed without an alarm, the screw is moved backward and forward alternately predetermined times. A servomotor for rotating the screw is driven in the same manner to detect an excessive load on the screw. Since the excessive load on the screw is directly detected, the excessive load is securely detected.

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 step time display device for an injection molding machine selects two events (a time measurement start event and a time measurement end event), time of each of which is to be measured, from among a plurality of events (starts and ends of mold clamping, injection, holding pressure, metering, mold opening, and ejection steps) in one molding cycle of an injection molding machine, and detects and stores occurrence time of each of the selected events. The step time display device calculates a time interval between the two events based on the occurrence time of each of the two stored events, and displays the calculated time interval on a screen.

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 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： A method of using a chip identification device is jointly performed by a chip mass-produced by a semiconductor manufacturing process, a first chip manufacturer making the chip, and a chip user assembling a product by using the chip. The method includes inputting a first published passcode, published by the first chip manufacturer, inputting a second published passcode published by a second chip manufacturer, inputting the first published passcode to the chip by the chip user, reading an aggregate of electronic output signals as a read code, sending the read code to the first chip manufacturer to compare the first output code and the read code. The chip is regarded as a counterfeit if the comparison is consistent.
