A management system of injection molding machines includes molding cells, each of which including at least an injection molding machine and a temporary storage device configured to store data from devices in each molding cell at prescribed intervals, and a management device that is connected with the molding cells through communications lines and stores the data stored in the temporary storage device. The temporary storage device overwrites the data sequentially from the oldest data to the newest data in cycles, and stores the data for a prescribed number of cycles. A signal that is selected in advance from signals generated by the devices in each molding cell or by the management device is input to the temporary storage device as a trigger signal, and when the temporary storage device receives the trigger signal, the temporary storage device outputs the stored data to the management device.

The present disclosure provides a molding machine and a method of molding a part. The molding machine may include multiple molding systems (e.g., extruders) for pumping molten material into one or more mold cavities. The multiple molding systems may pump the same material or different materials into the one or more mold cavities. The multiple molding systems may be individually and/or collectively controlled. A method of molding a part may include pumping material into one or more mold cavities via multiple molding systems, ceasing pumping material into the one or more mold cavities when one or more pressures associated with the multiple molding systems are achieved, and releasing a molded part from the one or more mold cavities after the one or more pressures are achieved.

A method for operating a molding machine includes specifying a simulating domain corresponding to a genuine domain in a mold disposed on the molding machine. The method proceeds to perform a virtual molding by using a setting packing pressure profile to generate a simulated state waveform, generating a designed state waveform including an isobaric phase and an isochoric phase while taking into consideration the simulated state waveform, and obtaining an updated packing pressure profile for applying a molding pressure to a portion of the genuine domain while taking into consideration a difference between the simulated state waveform and the designed state waveform. Subsequently, the method proceeds to set the molding machine while taking into consideration the updated packing pressure profile to perform an actual molding by applying an actual molding pressure to the at least a portion of the genuine domain to prepare the molding product.

A method for the representation and operation of production resources, in particular for the plastics-processing industry, on one or several central operating units, preferably a computer or control station. Symbols for the production resource connected via a network or the management tools associated with the production resource, such as configuration systems or database systems, are present and selectable on the central operating unit, wherein after selection of one or several symbols on the screen of the operating unit, the visualization, in particular the visualization component from the associated production resources or management tool is started or executed on the operating unit. Subsequently, complete representation and operation is possible through the cooperation of the visualization software available at the operating unit and a control software running decentrally in the production resources.

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.
