摘要： During metering, a screw is retreated to a preset metering completion position while it is being forwardly rotated. Pilot injection is performed such that the screw is reversely rotated and advanced so that a resin pressure reaches a predetermined compression pressure, during a time period between the end of the metering and the start of injection. The screw reverse rotation is continued before the screw advance is started for the pilot injection. In this way, a check valve can be closed at a relatively low pressure such that precision metering can be achieved.

摘要： A movable unit in an injection molding machine is started to operate and the current physical quantity and the current time (or current position of the movable unit) are detected. The current physical quantity is stored as a reference physical quantity in association with the elapsed time of operation of the movable unit (or position of the movable unit). A deviation of the current physical quantity from the reference physical quantity is calculated and stored, a distribution index value is then calculated from the physical quantity deviations in the first to n-th cycles, and a threshold value is determined from the distribution index value. When the deviation exceeds the threshold value, alarm processing is performed.

摘要： A notched region in which the outer periphery of a screw flight is cut out is provided in a molding material feed screw. A wedge-shaped portion is formed by both a front wall surface of the screw flight and a wall surface of the boundary where the outer periphery of the screw flight is cut out. As a result of rotation of the molding material feed screw, since the wedge-shaped portion advances while pushing aside resin pellets located in the front thereof in two lateral directions of the front wall surface of the screw flight and the wall surface of the boundary where the outer diameter of the screw flight is cut out, entrapment of the resin pellets between the edge of a material supply port of a molding material supply device and the outer periphery of the screw flight is avoided as much as possible.

摘要： An injection molding machine capable of accurately detecting a rotational force exerted on a screw by resin backflow to easily evaluate states of resin backflow and closure of a check valve. In a state where the screw is stopped axially and rotationally after metering is finished, a load exerted on the screw in the rotational direction is detected. This load is a rotational force exerted on the screw from resin remaining between flights of the screw (resistance torque component). During injection, a load T exerted on the screw in the direction of rotation is detected, and the resistance torque component is subtracted from the detected load T to obtain a backflow torque component generated by resin flowing back through the check valve. By simultaneously displaying waveforms of backflow torque components in a plurality of molding cycles to be overlapped, stability of closure of the check valve is readily evaluated.

摘要： An injection molding machine estimates a check valve wear amount, making it possible to predict a check valve use limit. At start of injection, the check valve is at a position advanced a stroke S0 with respect to a screw position (a position of a check seat that contacts the check valve and closes a resin flow channel). As the screw advances, the check valve retreats and closes when the screw moves a distance X0. When the check valve is worn ΔS (S1=S0+ΔS), it closes when the screw moves X1. Since the check valve stroke and the distance the screw moves until the check valve closes are proportional, S0/X0=S1/X1=a. Therefore, ΔS=aX1−S0, and the wear amount ΔS can be obtained by detecting the check valve closing position X1 and using this position X1 and the known stroke S0. The closing position is detected from the peak value of rotational force acting on the screw. Once the wear amount is obtained, the check valve use limit can be predicted from an allowable value of wear.

摘要： While a check ring of a screw of an injection molding machine is in open state, an absolute value (|Δ resin pressure / Δ rotation amount |) of a variation of a resin pressure per unit variation of the screw reverse rotation becomes greater than a predetermined reference value. However, after the check ring is closed, |Δ resin pressure / Δ rotation amount | becomes equal to or less than the reference value. From this, detecting if the |Δ resin pressure / Δ rotation amount | during reverse rotation of the screw, it is possible to determine that the check ring is closed or not. As a result, it is possible to obtain a screw reverse rotation amount which is optimal for reliably closing the check ring.

摘要： When the screw moves forward, resin backflow occurs. The backflow acts on the screw, applying torque to the screw. During forward movement of the screw, screw torque is produced as shown in FIG. 3A if the check ring is not worn, or as shown in FIG. 3B if the check ring is worn, because wear increases the backflow and delays the closure of the check ring. The magnitude of the peak screw torque and the associated time and screw position vary depending on the presence or absence of wear, so wear of the check ring is estimated from variations in these physical quantities. The state of wear of the check ring, screw head, check seat, and other parts inside the barrel can be estimated

摘要： Torques and resin pressures applied to a screw are detected during the forward movement of the screw and coefficients of correlation between the detected torques and resin pressures are calculated. When the check ring is open, the flight of the screw receives resin pressure, and the screw torque increases proportionally to the resin pressure due to resin backflow, so the coefficients of correlation between the screw torques and the resin pressures are higher than a reference value. When the check ring closes, the flight of the screw no longer receive resin pressure, so the screw torque decreases and the coefficients of correlation become lower than the reference value. The check ring is determined to be closed when the coefficients of correlation become lower than the reference value.

摘要： An injection molding machine capable of appropriately adjusting a control condition for a reverse rotation of a screw and a method for adjusting the control condition. Molding is repeated with an amount of a reverse rotation of the screw performed after completion of metering and before injection to be varied in each molding cycle. In injection, resin flows backward until a check valve becomes closed. A peak value of a rotational force causing reverse rotation of the screw by the back flow of resin and other physical amounts are detected as indices of resin back-flow amount. An evaluation value of the control condition is obtained by inputting the indices of resin back-flow amount, metering time, etc. into an evaluation function. The value of screw reverse rotation amount with which the highest evaluation value is obtained is set for the screw reverse rotation.
