A molding machine includes an injection device to inject a molding material into a mold and a control device to control the injection device. The injection device includes a heating cylinder filled with the molding material and a screw moving forward/backward inside the cylinder to inject the molding material, and can move forward/backward between a communication orientation where a distal end of the cylinder communicates with the clamped mold and a separation orientation where the distal end separates from the mold and can pivot on a pivot shaft between the separation orientation not allowing insertion/removal of the screw and a pivot orientation allowing the insertion/removal. The molding machine further includes a sensor to detect these orientations. The control device determines that the screw has been replaced by the sensor detecting that the injection device pivots from the separation orientation to the pivot orientation and returns to the separation orientation.

An external signal control device and a molding machine are provided that facilitate setting for connecting again an external device having been connected once. A control unit 7 is used for an injection molding machine. The control unit 7 has an optional output signal port OP1 to be connected to an external device, a storage device 73 to store control information of the optional output signal port OP1, and a control device 78. The control information includes signal port use information and output condition information. If the signal port use information is ON, the control device 78 controls the optional output signal port OP1 based on the output condition information, and if the signal port use information is OFF, controls the optional output signal port OP1 so as to cause the optional output signal port OP1 to not function.

A molding machine includes: an injection device to inject a molding material into a cavity of a clamped mold; a display device to display information; a memory capable of storing condition data sets that include setting values; and a control device to control the injection device according to one data set preselected from the data sets stored in the memory. The control device selectively executes a selected condition display process of listing the setting values in the selected condition data set on the display device and a stand-by condition display process of listing the setting values in a stand-by condition data set (one of the condition data sets different from the selected condition data set) on the display device, and in the stand-by condition display process, causes the display device to display the setting values identical to and different from those of the selected condition data set in different modes.

An injection molding machine is provided, wherein a display device displays screens requesting an operator to manipulate the injection molding machine in order in accordance with a manipulation procedure for the injection molding machine from automatic setting of initial molding conditions until actual molding of a molded article, and a guidance showing the manipulation procedure.

An injection molding machine changes a display position of a first image based on a change instruction that is input by a user.

An injection molding machine management system, which manages an injection molding unit including an injection molding machine and a peripheral device that performs a previous step or a subsequent step of a molding step, includes a first display unit that displays a first screen for displaying a state of the molding step of the injection molding machine. The first screen includes a first screen area and a second screen area. The first screen area displays a first indicator related to quality in the molding step of the injection molding machine, and the second screen area displays a second indicator related to quality in the previous step of the molding step or the subsequent step of the molding step.

An information processing system includes an acquisition unit that acquires an inference result of information relating to injection molding inferred based on information relating to a shot in the injection molding and information obtained in the shot; and a display control unit that causes a display unit to display a display screen which includes a waveform diagram indicating a temporal change in an actual value obtained in the shot, by using a waveform, and on which reference information based on the inference result is added to the waveform diagram.

A monitoring device for an injection molding machine includes circuitry configured to acquire first data from a sensor provided in an injection molding machine, the first data indicating detection results in a time series; input the first data into a trained model and acquire a first value from the trained model, the first value representing an evaluation of a product, the trained model being trained by machine learning with training data, the training data combining second data and a second value, the second data indicating detection results from the sensor in a time series, and the second value representing an evaluation of the product produced by the injection molding machine; and determine whether an abnormality has occurred in the detection results of the sensor, based on the acquired first value by the inferring unit.

A molding management system including a server and managing production of a product in a production process including an injection molding process of the product by an injection molding device, wherein the server is communicably connected to a terminal device and configured to cause the terminal device to display production plan information indicating a production plan for a designated first product in response to an operation received from the terminal device and the production plan information includes first operating time period information indicating a first operating time period in which the injection molding device is operated to produce the first product and inoperable time period information indicating at least an inoperable time period during which the injection molding device cannot be operated to produce the first product.

A molding machine management system includes: an injection molding machine including a mold, an injection unit, and a mold clamping unit; a management server coupled to the injection molding machine via a network; a first camera configured to capture an image of the mold; a second camera configured to capture an image of a drive unit provided in the injection molding machine; and a storage unit that stores first moving image data which is moving image data of the mold captured by the first camera, and second moving image data which is moving image data of the drive unit captured by the second camera, in association with a shot number of the injection molding machine. The management server includes a control unit configured to cause a display unit to display the first moving image data and the second moving image data in association with the shot number.
