An apparatus for taking out a molded product that is capable of suppressing displacement vibration of an attachment in a shorter time than ever without using a large-scaled electric actuator. An active controller performs active control in conjunction with the positioning, control by the servomotor. At the beginning of the active control, the positioning control is primarily performed by the servomotor, and then the active control is positively performed by the active controller using an electric actuator. Compared with when only the active control is performed for vibration suppression, a lighter and smaller electric actuator can be employed.

An apparatus for taking out a molded product that is capable of suppressing displacement vibration of an attachment in a shorter time than ever without using a large-scaled electric actuator. An active controller starts active control after the amplitude of displacement vibration of the take-out head as an attachment has been attenuated to a predetermined setting by means of positioning control by a servomotor or when the amplitude can be considered as having been attenuated to the predetermined setting. The positioning control is first performed by the servomotor, and then the active control is performed by the active controller using an electric actuator which is light in weight and small in size.

A molding system for assembling a part by moving a workpiece gripped by a hand of a robot toward a mold of an injection molding machine, while rotating a molded article supported on the mold and the workpiece relative to each other, whereby the molded article and the workpiece are screw-engaged. The molding system includes a rotation detector for detecting a rotational amount between the molded article and the workpiece, an assembled state judging unit for judging if the assembled part is in a predetermined state, and a control unit for relatively rotating and displacing the molded article and the workpiece until the rotational amount exceeds a predetermined rotational amount and the assembled state becomes the predetermined state.

The internal space of a storing container is separated by a flexible membrane into a first storing space storing an ejection material and a second storing space storing an operating liquid. A change in electrical property of the flexible membrane resulting from entry of at least one of the ejection material and the operating liquid to the inside of the flexible membrane is detected.

A molding system capable of performing highly accurate work on a molded article with a molded article removal device. The molding system includes a molding machine, a molded article removal device capable of removing a master work installed in a mold of the molding machine, a measurement section configured to measure a position of the master work when the master work is removed by the molded article removal device, a displacement calculation section configured to calculate a difference between a reference position and a detected position of the master work measured by the measurement section as a displacement, and a correction section configured to, on the basis of the displacement calculated by the displacement calculation section, correct a work position for when the molded article removal device performs work on a molded article.

A three-dimensional printing method for a three-dimensional printing system including a tank, a platform, an injection module, a warning module, a curing module, and a control module is provided. The control module is electrically connected to the curing module, the injection module, and the warning module. The method includes: analyzing a required amount of the liquid forming material corresponding to a three-dimensional object; obtaining a safe amount of the liquid forming material in the tank; and comparing the required amount and the safe amount, wherein the control module provides a response signal to the injection or warning module when the safe amount is less than the required amount. The injection module receives the response signal to inject the liquid forming material to the tank. The warning module receives the response signal to remind a user to provide the liquid forming material to the tank.

A control device controls an operation of an injection molding machine that advances and retracts an ejector rod of an ejector unit. The control device is configured to set a plurality of operation modes including a first operation mode and a second operation mode in which the injection molding machine is operated. The control device sets, at different positions from each other, a first retraction position where the ejection rod retracts to and waits in the first operation mode and a second retraction position where the ejection rod retracts to and waits in the second operation mode.

An injection molding machine has a clamp that generates electromagnetic force and that secures a moving plate or a fixed plate using attractive force that is produced by the electromagnetic force; and a controller that controls separation force that acts on the moving plate or the fixed plate such that the separation force is less than the attractive force.

An injection molding machine has a clamp that generates electromagnetic force and that secures a moving plate or a fixed plate using attractive force that is produced by the electromagnetic force; a pressure sensor that is provided in the clamp, wherein the pressure sensor measures contact pressure that acts between the moving plate or the fixed plate and the clamp; and a controller for performing a measure to prevent detachment of the moving plate or the fixed plate based on the contact pressure.

A method of operating an injection molding machine includes translating a movable platen from a closed position to a part transfer position by overshooting the transfer position in an opening direction away from a stationary platen to an over-travel position, and then translating the moving platen back to the transfer position in a closing direction, opposite the opening direction. Movement of a take-out device towards an advanced position, in which the take-out device reaches between mold halves carried by the stationary and movable platens, occurs while the movable platen is moving between the over-travel and transfer positions, prior to coming to rest in the transfer position. When resting in the transfer position, the method includes transferring molded articles from a first mold section mounted to the movable platen to retained engagement on the take-out device reaching between the platens.
