  • Patent number: 11897176
    Abstract: An injection molding machine having vent mechanism includes a plastication device, an injection device, a junction, a vent-up sensor, and a controller. The vent-up sensor detects vent-up. When the vent-up is detected, the controller switches from normal conditions to vent-up suppression conditions. The vent-up suppression conditions have at least one of the followings: increasing a rotational speed of the plastication screw to be higher than that in the normal conditions; using retreat-metering when the retreat-metering is not performed in the normal conditions, wherein in the retreat-metering, in addition to a pressure of the resin material, a force in a retreat direction is applied to the injection plunger to move the injection plunger at a predetermined retreat speed in the metering; and increasing the retreat speed of the injection plunger to be higher than that in the normal conditions when the retreat-metering is performed in the normal conditions.
