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： 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： A temperature control device for a proximal portion of a heating cylinder of an injection molding machine capable of performing check and control of a flow rate of a heat medium easily, improving maintainability and also reducing a manufacturing cost. At least one pair of through holes for flowing the heat medium for temperature control are formed in a jacket to be attached to a proximal portion of a heating cylinder of an injection molding machine. In a passage by pipes connecting the through holes and forming the passage with the through holes, a flow-rate control mechanism and a flow-rate detection mechanism for the heat medium flowing in the passage are arranged. The heat medium is supplied to the passage to control temperature of the proximal portion of the heating cylinder. The flow-rate control and detection mechanisms are arranged on the same side as an operation panel of the injection molding machine, whereby an operator can check and control the flow rate of the medium at the same location where an ordinary operation of the injection molding machine is performed.
