摘要： A lubricant such as grease is supplied by a grease supply device to a grease supply point of an injection molding machine. A workload of a movable portion forming the injection molding machine when the movable portion operates is calculated and a grease supply command is output to the grease supply device when the calculated workload exceeds a reference value. An operating state of the injection molding machine is evaluated by using the workload reflecting a load on the movable portion and, in this way, insufficiency of lubrication of the movable portion is anticipated.

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.

摘要： A monitoring device for an injection molding machine whereby the state of resin sheared by a rotating screw can be easily monitored. During the period from the start to end of metering process, the rate of heat generated by a heater for heating an injection cylinder is obtained by multiplying an on/off ratio B of the heater by a coefficient K and stored in a memory location THmem(n). Also, a time elapsed from the start of the metering is obtained by adding up a processing period T and stored in a memory location Tim(n). The heat generation rates of the heater stored in memory and corresponding to the respective elapsed times are displayed in graph form. The temperature of the injection cylinder represents heat generated by the heater plus heat generated due to resin shearing. Since the heat generation rate of the heater is detected, the rate of heat generated due to resin shearing can be grasped relatively from the detected heat generation rate, making it possible to monitor the state of the resin sheared by the rotating screw. The resin shearing state can be monitored by simple processing of detecting and displaying the heat generation rate of the heater.

摘要： A resin flow analysis in a die is performed by CAE or the like to obtain a resin pressure curve at a resin inlet port or a resin pressure curve at a nozzle end portion of a molding machine. Injection (air shot) is performed while a nozzle is separated from a die, so that an injection pressure curve Pa to be detected at this time is obtained. From the injection pressure curve and the resin pressure curve, an injection pressure command curve serving as a molding condition in mass production is obtained. The resin pressure curve obtained by the resin flow analysis is compensated by the injection pressure curve in an air shot for a time lag and pressure loss caused by the mechanical elements of an injection molding machine, so that molding conditions in mass production can be easily obtained. In addition, a pressure loss at the nozzle portion is also obtained, so that an injection pressure command curve is obtained from the pressure loss, the injection pressure curve, and the resin pressure curve.

摘要： When a resin passage of a check ring is opened, resin backflow occurs during time when an injection screw is moved forward, and a reverse rotational force is applied to the screw by resin backflow. On the other hand, when the resin passage is closed, there is no resin backflow and the reverse rotational force applied to the screw is greatly reduced. Consequently, after completion of metering process and before injection process, the screw is moved forward after the screw has been rotated in reverse a predetermined amount to prevent resin backflow. At this time, a maximum value of the reverse rotational force applied to the screw is detected. Until the detected maximum reverse rotational force reaches a reference value or less, the reverse rotation amount is increased sequentially and respective molding cycles are carried out. When the detected maximum reverse rotational force reaches the reference value or less (passage closure), the reverse rotation amount at this time is set as the reverse rotation amount for the reverse rotation process. By means of this operation, an optimal reverse rotation amount can be adjusted automatically.

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.
