    摘要: A method of performing an injection molding cycle in an injection molding apparatus (10) comprising a manifold (40) that receives an injection fluid (1153), the manifold distributing injection fluid to a fluid delivery channel (44) that delivers the injection fluid under an injection pressure to a gate (34) of a mold cavity (30) and a valve pin (1041) having an axis (A) and a tip end (1142), the valve pin being slidably mounted for movement along the axis within the fluid delivery channel (44), is characterized in that itcomprises,
    drivably interconnecting the valve pin (1041) to an electric motor driven (941) by a source of electrical power or energy in an arrangement wherein the electric motor drives the valve pin along the axis (A) and drives the tip end (1142) of the valve pin between a first position (GC), a second position (COP, COP2, COP3) upstream of the first position (GC) wherein the tip end of the valve pin restricts flow (1154) of the injection fluid along at least a portion (RP, RP2, RP3) of the length of the drive path extending between the first position and the second position, and a third maximum upstream position (EOS) where the injection fluid material flows freely without restriction from the tip end of the pin through the first gate,
    selecting a length of travel between the first position and the second position,
    beginning an injection cycle with the tip end of the valve pin in the first position, controllably operating the electric motor to drive the valve pin at one or more intermediate rates of upstream travel greater than zero and less than the maximum rate of upstream travel to drive the tip end of the valve pin upstream from the first position to the second position, along at least a portion (RP, RP2) of the length of a drive path extending between the first position (GC) and the second position where the tip end of the valve pin restricts flow (1154) of the injection fluid and further upstream to the third maximum upstream position.
    selecting a length of travel between the third maximum upstream position (EOS) and a predetermined third position (COP, COP2, COP3) that is downstream of the maximum upstream position (EOS) and upstream of the first position (GC),
    sensing the position of the valve pin to determine when the tip end (1142) of the valve pin has reached the preselected third position (COP, COP2, COP3) during the course of downstream travel,
    controllably operating the motor (941) to drive the valve pin (1041) at one or more intermediate rates of downstream travel that are less than the one or more high rates of downstream travel when the tip end (1142) of the valve pin has been determined in the step of sensing to have reached the third position (COP, COP2, COP3) to drive the tip end of the valve pin downstream from the third position (COP, COP2, COP3) through at least a portion (RP, RP2) of the length of the drive path extending between the first position (GC) and the second position where the tip end of the valve pin restricts flow (1154) of the injection fluid to the first position (GC).

    摘要: When a resin passage of a check ring (4) is opened, resin backflow occurs during time when an injection screw (1) is moved forward, and a reverse rotational force is applied to the screw (1) 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 (1) is greatly reduced. Consequently, after completion of metering process and before injection process, the screw (1) is moved forward after the screw (1) 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 (1) 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.

    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.
