摘要： When a metering process is started, a screw rotates at a preset rotating speed, thereby carrying out back pressure control to keep the pressure of a resin at a preset pressure, and retreats. When the screw is located near a preset metering completion position, the control mode is switched to positioning control for the preset metering completion position, and a screw rotation stop command is outputted. The screw overruns for some distance before its rotation stops after it retreats and stops at the preset metering completion position. A resin quantity for the overrun is corrected to obtain a preset metered resin quantity by reversely rotating the screw by a rotational amount corresponding to the overrun.

摘要： A mold is mounted with a locating ring mated into a hole in a stationary platen. A distance measuring unit is disposed to the side of the injection nozzle. The distance A between the sprue hole and the outer circumference of the locating ring and the distance B between the distance measuring unit and the outer circumference of the locating ring are both known. The distance C between the central axis of the nozzle hole and the side of the injection nozzle is also known. If the distance D to the side of the injection nozzle is measured by means of the distance measuring unit, the displacement between the central axis of the sprue hole and the central axis of the nozzle hole is obtained by calculating {(A+B)−(C+D)}. The injection nozzle is centered by being moved manually or automatically by the amount corresponding to the displacement.

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： The invention provides an injection molding capable of adjusting a detection level with a simple structure and detecting a deposit level of the resin pellets near a plasticizing screw. A cooling jacket is mounted so that a resin supplying hole of the cooling jacket communicates with a resin supplying hole of a heating cylinder. A sensor head mounted on a sensor mounting plate is inserted into the resin supplying hole through a sensor insertion port provided on a hopper plate and a resin inlet and detects the deposit level of the resin pellets deposited in the resin supplying hole. Changing the extent of insertion of the sensor head enables the resin pellets deposit detection level to be changed, and further, enables the deposit level near the outer periphery of the screw to be detected. Setting the sensor detection direction perpendicular to the resin deposit direction enables dirtying of the sensor detection surface by the resin pellets to be reduced, thus enabling erroneous detection readings to be reduced.

摘要： A controller for an injection molding machine capable of reducing an extension of a cycle time in a screw retreat process after the end of measurement, obtaining a more accurate and uniform measured resin amount, and determining measurement conditions in a short period of time. After the measurement is finished, the screw is stopped from rotating and retreated at a first speed V1. The screw is reversely rotated at a predetermined speed Rv in a set zone. As this is done, the screw is retreated at a second speed V2 lower than the first speed V1. After the reverse rotation zone is terminated, the screw is stopped from rotating and retreated at a third speed V3 to a set retreat stop position. By doing this, the cycle time can be made shorter than in the case where the retreat and reverse rotation of the screw are performed separately. Since the retreating speed of the screw is low while the screw is being reversely rotated, a sudden pressure change can be suppressed, so that precise measurement can be made. Since conditions for the reverse rotation and retreat of the screw can be regulated independently, they can be adjusted to optimum conditions in a short period of time.
摘要翻译：一种用于注射成型机的控制器，其能够在测量结束后减少螺杆后退过程中的循环时间的延长，获得更精确和均匀的测量树脂量，并在短时间内确定测量条件。测量结束后，以第一速度V 1停止螺杆旋转和退回。螺钉以设定区域中的预定速度Rv反向旋转。这样做，螺杆以比第一速度V 1低的第二速度V 2退避。在反向旋转区域终止之后，螺丝停止旋转并以第三速度V 3退回到设定的退避停止位置。通过这样做，循环时间可以比在单独进行螺杆的后退和反向旋转的情况下更短。由于当螺杆反向旋转时螺杆的后退速度低，所以可以抑制突然的压力变化，从而能够进行精确的测量。由于可以独立地调节螺杆的反转和后退的条件，所以可以在短时间内将其调节到最佳状态。
