[0029] Traditionally, the electrical energy consumed per injection cycle and the average time of electrical energy consumption in an injection molding machine are calculated, and the results are displayed on a screen. However, if the physical quantities of the resin used for molding change, such as volume or mass, the average time of electrical energy consumption in the injection molding machine will also change. Therefore, even comparing the average time of electrical energy consumption between molded products with different volumes and masses of resin used may not provide a useful evaluation of the electrical energy consumption of the injection molding machine.

[0030] According to the technology disclosed herein, it is possible to obtain the electrical power consumption per unit physical quantity for physical quantities related to the amount of resin used for molding and physical quantities related to the number of molded articles. Therefore, a useful evaluation of the electrical power consumption of the injection molding machine can be made.

[0031] [First Implementation]

[0032] [Structure of an information processing device]

[0033] Figure 1 This is a block diagram of the information processing device 10. The information processing device 10 can also be a control device for controlling the injection molding machine 12.

[0034] The information processing device 10 includes an arithmetic unit 14, a storage unit 16, and a display unit 18. The arithmetic unit 14 is, for example, a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). The arithmetic unit 14 includes an acquisition unit 20, a calculation unit 22, and a display control unit 24. The acquisition unit 20, the calculation unit 22, and the display control unit 24 are implemented by executing a program stored in the storage unit 16 within the arithmetic unit 14. At least a portion of the acquisition unit 20, the calculation unit 22, and the display control unit 24 can be implemented using integrated circuits such as ASICs (Application Specific Integrated Circuits) or FPGAs (Field-Programmable Gate Arrays). At least a portion of the acquisition unit 20, the calculation unit 22, and the display control unit 24 can also be implemented using electronic circuits containing discrete components.

[0035] Storage unit 16 is a computer-readable, non-temporary tangible storage medium. Storage unit 16 comprises volatile memory (not shown) and non-volatile memory (not shown). Volatile memory includes, for example, RAM (Random Access Memory). Non-volatile memory includes, for example, ROM (Read Only Memory), flash memory, etc. Data is stored, for example, in volatile memory. Programs, tables, mappings, etc., are stored, for example, in non-volatile memory. At least a portion of storage unit 16 may also be disposed in the aforementioned processor, integrated circuit, etc. At least a portion of storage unit 16 may also be mounted in a device connected to information processing device 10 via a network.

[0036] The acquisition unit 20 acquires information on the electrical power consumed by the injection molding machine 12 during the molding of the molded article. The electrical power consumed by the injection molding machine 12 during the molding of the molded article represents, for example, the electrical power consumed by the injection molding machine 12 in the injection process, the holding pressure process, the measuring process, etc.

[0037] The electrical power consumed by the injection molding machine 12 during molding is not limited to the electrical power consumed within the injection molding machine 12 itself, but may also include the electrical power consumed in the information processing device 10. The electrical power consumed by the injection molding machine 12 during molding may also include the electrical power consumed in peripheral equipment such as the hopper that supplies resin to the molding machine body and the robot that removes the molded product. The electrical power consumed by the injection molding machine 12 during molding may also be the electrical power consumed per injection, the electrical power consumed at regular intervals (e.g., every hour), or the electrical power consumed per production planning unit.

[0038] The calculation unit 22 calculates the electrical power consumed per unit physical quantity by dividing the electrical power consumed by the injection molding machine 12 by a predetermined physical quantity. In this embodiment, the predetermined physical quantity refers to the volume of resin injected by the injection molding machine 12 when molding the molded article. The predetermined physical quantity may also be the volume remaining after deducting the volume of the slide valve, the volume of the runner, and the volume of the gate from the volume of resin injected by the injection molding machine 12 when molding the molded article. In this embodiment, the unit physical quantity represents the unit volume. In this embodiment, the unit volume is 1 [cm^3]. The unit volume may also be other volumes.

[0039] The volume of resin injected during the molding process of the injection molding machine 12 is determined based on the movement and diameter of the screw. Alternatively, the volume of resin injected during molding can be determined from the design data of the metal mold installed on the injection molding machine 12. Finally, the volume of resin injected during molding can be determined from the measured data of the metal mold installed on the injection molding machine 12.

[0040] The display control unit 24 controls the display unit 18 to display information indicating the power consumption per unit volume.

[0041] The display unit 18 is, for example, a liquid crystal display or an organic light-emitting diode display. The display unit 18 may also be provided in a device other than the information processing device 10.

For example... Figure 2 As shown, information on the electrical power consumption per unit volume of each molded article is displayed on the display unit 18. This allows for comparison of electrical power consumption between molded articles of different volumes. Therefore, a useful evaluation of the electrical power consumption of the injection molding machine 12 can be obtained.

[0043] Furthermore, regardless of the type of molded product, information indicating the electrical power consumed per unit volume can also be displayed on the display unit 18.

In this case, even if the power consumption per unit volume of resin and the power consumption per unit mass of resin are the same in molded articles P and Q, the power utilization efficiency in the molding of molded article P is higher than that in the molding of molded article Q.
