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： 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： 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.
