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.

An injection molding machine includes a first mold section comprising mold cores for forming threaded articles, the first mold cores movable between a molding position for interacting with a second mold section in a mold area to form the threaded articles, and an auxiliary position outside the mold area, and a removal device for removing the threaded articles from the mold cores. The removal device includes a plurality of unscrewing chucks for engaging the threaded articles when the mold cores are in the auxiliary position. The chucks are supported by a carrier plate and each chuck is rotatable about a respective unscrewing axis. The removal device further includes an orbiting plate coupled to the unscrewing chucks by respective crank arms, the orbiting plate effecting synchronized rotation of the unscrewing chucks via the crank arms for unscrewing the threaded articles from the mold cores.

A method for cooling molded preforms includes transferring preforms of a first injection cycle from a mold to retained engagement on a take-out plate, the preforms having exterior surfaces and interior surfaces targeted for cooling. The preforms are released from cooling tubes of the take-out plate to retained engagement on cooling pins of a transfer shell spaced away from the mold. The transfer shell rotates and the preforms are released from the transfer shell to retained engagement in supplemental tubes of a supplemental cooling device. After a period of time the preforms are released from the supplemental cooling device and transferred back to retained engagement on the transfer shell. The transfer shell rotates to an unload position to eject the preforms from the transfer shell for evacuation from the machine.

Extractor systems for extracting a flexible article of manufacture from a mold include an extraction roller, at least one track configured to support the extraction roller, and a trolley configured to carry the extraction roller from a first side of the mold toward a second, opposite side of the mold. Molding systems include a mold and an extractor system. Methods of extracting a flexible article of manufacture from a mold include separating a first platen and a second platen, positioning an extraction roller between the separated first and second platens, engaging the article of manufacture with a row of teeth positioned along the extraction roller, and rotating the extraction roller to wrap the article of manufacture about the extraction roller.

The three-dimensional geometry of an attachment is measured before work is started. A maximum dimension of a take-out head 60 in the X direction, a maximum dimension of the take-out head 60 in the Y direction, and a maximum dimension of the take-out head 60 in the Z direction are measured on the basis of an image of the take-out head 60 captured by at least imaging devices C11 and C12 before the take-out head 60 starts work with the take-out head 60 being mounted to an elevating frame 59B of an apparatus 5 for taking out a molded product, as an orthogonal three-axis robot.

An injection molding machine includes a base; a pair of platens supported by the base, the platens supporting respective mold halves to form a mold; and a part-handling apparatus for holding and treating articles from the mold, the part handling apparatus separate from the mold. The part handling apparatus includes a take-out plate including at least one set of first cooling receivers for receiving and retaining a first set of molded articles from the mold, the first cooling receivers conductively transferring a first amount of thermal energy away from the first molded articles; and a supplemental cooling plate comprising at least one set of second cooling receivers for receiving and retaining the first set of articles; and the second cooling receivers conductively transferring a second amount of thermal energy away from the first molded articles.

This invention relates to a handling device for the removal of plastic injection-molded parts, designed as pipette tips, medical reaction vessels or contact-lens molds, from an injection mold tool (11), having a removal gripper having a plurality of receiving positions (1-32; 104, 105) for receiving one injection-molded part from each of the cavities in each instance.

A remote control system to remotely control a take-out robot of an injection molding machine on a production site through network includes an injection molding machine to produce and convey injection molded products through the take-out robot. A remote controller transmits and receives the operation data of the take-out robot and the information data on the injection molding to and from the injection molding machine through the wireless internet. The remote controller remotely controls the injection molding machine based on the utilized operation data and information data. A control pendent connected to the injection molding machine remotely controls the take-out robot, performs three-dimensional graphic simulation for the previous operations before operating the take-out robot and for loading motions of the injection molded products, and stores and outputs the three-dimensional graphic images of the injection molded products, based on a previously stored remote control access program.

Disclosed herein, amongst other things, is a method of transferring a molded article from a moveable mold half of a mold into a receptacle of a post-mold tool. The method includes positioning the moveable mold half relative to the post-mold tool to position the molded article thereon closer to the receptacle and retracting the moveable mold half while simultaneously extending a stripping device to eject the molded article from the moveable mold half and to transfer it into the receptacle.

A retaining pin for handling injection molded preforms includes a body including an internal body flow channel, and a plunger coupled to the body and movable relative to the body between advanced and retracted positions. The plunger includes an internal plunger flow channel. The plunger further includes a plunger abutment surface directed away from the body. The plunger is biased toward the advanced position and movable to the retracted position by engagement of the plunger abutment surface with an inner surface of a closed end of a preform when the preform and retaining pin are moved toward each other. The body flow channel and the plunger flow channel are in fluid communication when the plunger is in the retracted position. Fluid communication between the plunger flow channel and the body flow channel is inhibited when the plunger is in the advanced position.
