摘要： A stationary die is held on the front surface of a stationary platen and a movable die is held on the front surface of a movable platen. A plurality of monitoring sections are set in advance within a moving range of the movable platen and an upper limit of forward thrust of the movable platen is set for each of the monitoring sections. When the forward thrust of the movable platen reaches the upper limit set in one of the monitoring sections during a die closing operation, it is determined that abnormality occurs to stop the movable platen from moving forward. If a die closing mechanism is of a toggle link type, the forward thrust of the movable platen is calculated based on the thrust of a crosshead which drives a toggle link mechanism, the moving speed of the crosshead, and the moving speed of the movable platen.

摘要： A filling step control method of an injection molding machine for filling a molten resin into a die cavity is provided. The control method has the steps of: sampling in initiating the filling step for filling the molten resin into the die cavity by controlling an injection speed and, thereafter, by controlling a filling pressure while not exceeding a predetermined value; storing the injection speed over an entire filling process when a quality product can be stably obtained during the sampling step into a storage medium as a reference waveform; and after storing the reference waveform, molding for filling the molten resin into the die cavity by controlling the injection speed to follow the reference waveform over the entire filling step.

摘要： An object of the present invention is to suppress a clamping force from sharply increasing when dies are clamped in an electric direct-acting die clamping unit of an injection molding machine. A movable platen is arranged to face a stationary platen. A stationary die is attached to the front surface of the stationary platen, whereas a movable die is attached to the front surface of the movable platen. The movable platen is connected to the front surface of a backup plate via four coil springs. A nut of a ball screw is fixed at each of diagonally-opposed corners of the backup plate. The threaded rod of the ball screw passes through the backup plate via the nut. The tip portion of the threaded rod is rotatably connected to the stationary platen. The rear end portion of the threaded rod is connected to a motor.

摘要： The present invention is directed to a method of monitoring operation data for quality control with a little possibility that a nondefective product is mistakenly determined as a defective product even if the operation data fluctuates in a large waviness curve. Every time an operation data piece for quality control is obtained, a moving average of the predetermined number of data pieces lately obtained is calculated. When the deviation of a data piece from the moving average exceeds the tolerance limit, an alarm is generated. By employing the method of the present invention for monitoring operation data such as charging time, injection time and the amount of cushion in an injection-molding machine, the accuracy of determination as to a defective or nondefective can be improved.
摘要翻译：本发明涉及一种用于质量控制的操作数据监视的方法，即使操作数据在大的波纹曲线中波动，也可能将非缺陷产品错误地确定为缺陷产品的可能性很小。每次获得用于质量控制的操作数据块时，计算最近获得的预定数量的数据的移动平均值。当数据片与移动平均线的偏差超过公差限制时，会产生报警。通过采用本发明的方法来监视注射成型机中的充电时间，注射时间和缓冲量的操作数据，可以提高对缺陷或非缺陷的确定的准确性。
