Description

CROSS-REFERENCE TO RELATED APPLICATION The present application is based on and claims priority under 35 U.S.C. § 119 to Japanese Patent Application No. 2021-131361, filed on Aug. 11, 2021, the contents of which are incorporated herein by reference in their entirety. BACKGROUND 1. Technical Field The present invention relates to a control device of an injection molding machine, an injection molding machine, and a recording medium. 2. Description of the Related Art Various sensors have conventionally been installed in injection molding machines. Thus, in injection molding machines, a technology has been proposed to display, on a display device, waveform data representing, by waveforms, various processes during injection molding based on detection signals from sensors, or setting contents set by a user. In recent years, various techniques have been proposed to display waveform data on the display device of injection molding machines. For example, in the conventional technology, a technology to display information such as a mold closing position, in association with a variation curve of physical quantity, has been proposed. In recent years, a display input device, in which an operation device such as a touch panel and a display device are integrated, tends to be used as an interface for receiving an operation from a user. In such a display input device, the operation device and the display device are integrated, and, therefore, an operation can be performed while confirming the displayed contents. SUMMARY According to an embodiment of the present invention, there is provided a control device of an injection molding machine, the control device including an output part configured to output a display screen displaying waveform information indicating a change of at least one of setting information indicating a setting of a process of injection molding or an actual value according to the process, and a plurality of pieces of instruction information to set a range of the waveform information, the display screen being output to a display input device in which a display device and an input device are integrated, the display input device being configured to receive an operation in a screen area displayed by the display input device, the display input device being connected to the injection molding machine; and a receiving part configured to receive, from the display input device, an operation with respect to at least one of the plurality of pieces of instruction information displayed on the display screen. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 illustrates the state of an injection molding machine according to the first embodiment at the time of mold opening completion; FIG. 2 illustrates the state of the injection molding machine according to the first embodiment at the time of mold clamping; FIG. 3 is a diagram illustrating the elements of the control device according to the first embodiment in functional blocks; FIG. 4 illustrates an example of a display screen output by the output part according to the first embodiment; FIG. 5 illustrates an example of the display screen output by the output part according to the first embodiment; FIG. 6 is a flowchart illustrating the control performed when receiving a specification of a range specified in a selected range display field in the control device according to the first embodiment; FIG. 7 illustrates an example of a log information screen output by the output part according to the first embodiment; and FIG. 8 illustrates an example of the display screen output by the output part according to a second embodiment. DETAILED DESCRIPTION A conventional technology does not use a display input device such as a touch panel, but is simply a technology for appropriately recognizing a reference value by pointing a cursor at a variation curve; the conventional technology is not a technology for reducing the operational load. That is, in the conventional technology, because it is difficult to specify a range or the like with respect to the waveform data, it is difficult to specifically identify the situation represented by the waveform data. One aspect of the present invention provides a technology that can implement detailed quality control, because by specifying a range of waveform information by way of a display input device, it becomes possible to appropriately identify the situation indicated in the range. Embodiments of the present invention will be described below with reference to the drawings. Identical or corresponding configurations in each drawing may be given the same or corresponding symbols and explanations thereof may be omitted.
