An operation abnormality detection method for detecting an operation abnormality in a molding device having a movable part includes: acquiring a prescribed measured value relating to operation of the movable part and calculating, as statistical information, an average value of prescribed information values based on the prescribed measured values: calculating a first threshold and a second threshold; acquiring a current measured value and comparing a current information value based on the current measured value with the greater of the first threshold and the second threshold; and issuing a warning if the current information value at least exceeds the greater of the first threshold and the second threshold.

A control method for a mold opening/closing device including a hydraulic cylinder that opens and closes a mold, a hydraulic drive device that drives the hydraulic cylinder by supplying a hydraulic oil, and a controller that controls the hydraulic drive device, wherein the controller changes speed change in a deceleration region, in which movement of the hydraulic cylinder is decelerated, between a first half portion and a second half portion of the deceleration region, and causes speed change rate per unit time in the second half portion to be smaller than in the first half portion.

Mold opening/closing device and method for controlling mold opening/closing device

There is provided a resin container manufacturing apparatus configured to stretch a preform disposed in a stretch blow molding mold by a stretching rod and stretch the preform by introducing blow air into the preform so as to form a resin container. The resin container manufacturing apparatus includes detection means for detecting an actual position of the stretching rod inserted into the preform, and supply control means for controlling a supply state of the blow air based on a detection result of the detection means.

Resin container manufacturing device and manufacturing method

A manufacturing apparatus for manufacturing a resin molded article includes: an injection molding part configured to inject resin into an injection mold and injection-mold the resin molded article; a control unit configured to control the injection by the injection molding part; a calculation unit configured to calculate a pressure reduction curve for reducing a pressure generated by the injection; and an input unit via which a user inputs a condition of the pressure reduction curve, in which the control unit is configured to control the injection based on the pressure reduction curve.

Resin molded article manufacturing device, and manufacturing device control method

A blow molding machine for a resin container is provided with at least a blow molding section, a heating section, and a conveyance path for conveying a preform heated by the heating section to the blow molding section. The conveyance path is provided with a first conveyance member that is continuously and intermittently driven. The blow molding section is provided with a plurality of blow movable members. A plurality of conveyance driving sections for driving the first conveyance member are driven in synchronization with each other, and the blow movable members are driven in synchronization with each other.

Blow molding machine and method for controlling blow molding machine

This blow molding device is provided with: a display device configured to display on a setting screen information for setting control conditions for a plurality of objects to be controlled; and a display control device configured to control a display state of the setting screen. The display control device is configured to: cause a main display unit to display the information for setting the control conditions, as required; and cause a sub-display unit to constantly display status information which makes it possible to know operational states of the objects to be controlled, and a display switching icon for causing the main display unit to display operating icons of the objects to be controlled.

Blow molding device and interface device provided in blow molding device

As an injection screwapplies pressure, a holding pressure plungeris moved backward under the pressure of a resin to flow the resin into a holding pressure path, and the resin in a resin pathis pressurized (primary holding pressure process). A shutoff plungeris closed, and the resin in the resin pathand the holding pressure pathis pressurized by the holding pressure plunger(secondary holding pressure process). Further, the shutoff plungeris opened, and the holding pressure plungeris moved forward until its tip projects into the resin pathto discharge all the resin in the holding pressure pathto the resin path, whereby the resin beside the injection screwas compared with the shutoff plungeris held with respect to the holding pressure path
