In an injection molding system, a holding force changing means reduces a holding force to a predetermined level or less if a predetermined or higher load is detected by an external load detection means after a molded article is transported to a work area of an operator by a molded article transport device. Thus, the operator can easily take out and inspect the molded article.

A molding product taking-out system includes a molding machine that includes a stationary platen including a stationary mold and a movable platen including a movable mold, a take-out machine for taking out a molding product, and a control device, in which the control device causes the take-out machine to enter between the stationary mold and the movable mold that are opened, and moves at least one of the movable platen and the take-out machine such that the molding product relatively approaches the take-out machine.

An injection molding device includes a housing having a door, an injection molding machine, a detection section, and a control section. The control section controls voltage applied to the mold clamping motor, and performs mold-clamping and mold-opening of the upper mold and the lower mold by either moving the injection unit and the upper mold along the vertical direction or by moving the lower mold along the vertical direction. The mold clamping device further includes a first brake section that, when application of voltage to the mold clamping motor is stopped, regulates movement of the injection unit and the upper mold in the vertical direction or movement of the lower mold in the vertical direction. When the detection section detects that the door is open or detects intrusion of foreign matter, the control section stops application of voltage to the mold clamping motor.

The present invention involves a fabrication of plastic-tube-screen-fill (PTSF) injection mold fabricating PTSFs using molten plastics injection molding machine. The PTSFs replace PVC-film-fills currently using in water evaporative cooling towers. The PTSFs have a higher water cooling efficiency compared to the efficiency of the PVC-film-fills and therefore the PTSFs reduce the operation and construction expenses of the cooling tower, and also the PTSFs reduce the production of plastic wastes due to the utilizing of high cooling efficient media in the cooling towers. In order to commercialize the PTSFs, a manufacturing tool of the PTSFs to fabricate a low-cost plastic-tube-screen-fill is needed. To achieve this end, the PTSF injection mold is invented by comprising four partial-molds, which is operated in three dimensional disassembling and reassembling processes using a vertical injection molding machine.

An ejection device having a pushing device that can be moved in translation along a first axis, an ejection element is translatable along a second axis different from the first axis, and a transfer device connecting the pushing device and the ejection element. The transfer device includes a transmission chain having at least two transmission links which are translatable in a sliding direction. The ejection device further includes an adjustment wedge mounted on the pushing device, the adjustment wedge having an adjustment surface forming an adjustment angle, with the transmission chain being mounted on the adjustment surface.

A computing system may include an eject direction determination engine configured to determine an eject direction for an injection mold design, including by determining a set of candidate eject directions for the injection mold design, including a bounding box candidate eject direction determined based on a minimum bounding box of an object representative of a product to be manufactured through the injection mold design and selecting the eject direction for the injection mold design from the set of candidate eject directions based on eject direction determination criteria. The computing system may also include an eject direction application engine configured to set the determined eject direction for the injection mold design so that physical mold pieces constructed from the injection mold design are configured to separate from one another in the determined eject direction during an injection mold production process to manufacture the product.

A controller is configured to obtain a torque waveform of a servo motor while an ejector pin is operating, compare the torque waveform with a reference waveform obtained in advance, and determine that an ejector is abnormal when a difference between the torque waveform and the reference waveform exceeds a threshold value.

An injection molding machine includes: an acquisition unit configured to acquire, during a mold opening operation of a mold, at least one of a first measurement value relating to a resistance when a protrusion operation of an ejector pin to release a molding product from the mold in a mold-opened state is performed and a second measurement value relating to a resistance when an accommodation operation of the ejector pin is performed; and an estimation unit configured to estimate an amount of deposition of a mold deposit deposited on the mold, based on at least one of the first measurement value, excluding an element before the molding product is released or lowering a priority of the element, and the second measurement value.

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 mold apparatus of a pressure vessel includes an upper mold including an internal surface in a shape corresponding to a shape of an external surface of the pressure vessel provided with a nozzle with a closed inlet; a lower mold including an external surface in a shape corresponding to the shape of the internal surface of the pressure vessel, engaged with the upper mold, and formed with an air injection passage therein; an ejector injecting air through the air injection passage between the lower mold and the taken-out pressure vessel; an air injection rate setting device configured for controlling an injection rate of the air injected between the lower mold and the pressure vessel using the ejector; and a pneumatic controller interlocking with the air injection rate setting device and controlling a pressure of air injected.
