A production management device includes circuitry configured to display, on a display unit, detection results detected by a detection unit in a process of producing a product upon a plurality of products being produced by a production device; and display, upon receiving selection of a detection result or information for identifying the product, a detection result of a first product together with a detection result of a second product and a detection result of a third product on the display unit, the first product being identified by the detection result or the information for identifying the product, the second product being produced by the production device immediately before the first product, and the third product being produced by the production device immediately after the first product.

A molding machine management system includes a display section configured to display, along a common time axis, identification indicators for identifying a component B, which is a first molded article, and a component C, which is a second molded article, produced after the component B, a production result for the component B including a molding result period and an arrangement result period for the component B, and a production plan for the component C including a molding planned period and an arrangement planned period for the component C and display the production result for the component B and the production plan for the component C in parallel on the common time axis.

To provide a preview display function that enables preview display and confirmation of various setting operations of an injection molding machine, and an injection molding machine provided therewith. The above-described problem is solved by a preview display function for displaying a preview of operations of an injection molding machine, in whole or in part. The preview display function comprises a function for setting the operations of the injection molding machine, in whole or in part, on a setting screen, a function for displaying a preview display screen for displaying the operations thus set, and a function for playing back the operations on the preview display screen thus displayed. At this time, preferably the operations thus set are played back as a moving image displayed three dimensionally or two dimensionally, and the setting screen and the preview display screen are displayed side by side.

A display device of an injection molding machine includes a circuit configured to display a guidance screen that assists in providing conditions of an injection process. The injection process sequentially includes a filling process of controlling a travel speed of an injection member, a stopping process of stopping travel of the injection member, and a dwelling process of controlling a pressure applied from the injection member to a molding material. The guidance screen includes a first input field configured to receive an input of conditions upon completion of the filling process in a first test molding. In the first test molding, the filling process is performed under the conditions input to the first input field and subsequently the stopping process is performed, and then the dwelling process is performed under conditions that enable confirming a forward flow end position of the molding material upon completion of the stopping process.

In order to calculate a ball screw abrasion amount of an injection-axis ball screw or a mold-clamping-axis ball screw, a position of a ball nut fitted to the ball screw is photographed by a camera installed in an injection molding machine. Then, if the photographed position of the ball nut is found, as a result of analysis of an image captured by the camera, to be deviated from the position of the ball nut when a ball screw has no abrasion, it is determined that the ball screw is abraded.

In an injection molding system, an amount of deformation of an elastic member is calculated from image data of the elastic member causing a nozzle to generate a nozzle touch force and a nozzle touch force of the nozzle is calculated by converting the amount of deformation. Accordingly, it becomes possible to detect abnormal conditions such as resin leakage and mold deformation and exercise correct control of the nozzle touch force.

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.

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 performs, during a period of a flushing process, a first acquisition process for acquiring a physical quantity for detecting an abnormality of a first drive apparatus.

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.
