[0017] The resin flow analysis device analyzes the flow state of the resin in an injection molding machine and calculates the molding conditions set for the injection molding machine. However, the resin flow analysis device cannot completely reproduce the flow state of the resin in actual molding through analysis. Therefore, even if the molding conditions calculated by the resin flow analysis device are set in the injection molding machine, it is basically impossible to obtain qualified molded products in actual molding. Therefore, the user needs to adjust the molding conditions calculated in the resin flow analysis device. The adjustment of the molding conditions is carried out based on the molded products obtained in actual molding, the actual molding results, etc. and the analysis results obtained in the resin flow analysis device.

[0018] The analysis results obtained in the resin flow analysis device are displayed on the display unit. The analysis results correspond to each time point or each screw position in the analysis. The user can make the display unit display the analysis results corresponding to an arbitrary time point or screw position by operating a slider or the like that designates the time point or screw position in the analysis.

[0019] When the user adjusts the molding conditions, the user needs to select the analysis results corresponding to the molding conditions of the item to be adjusted and make the display unit display the selected analysis results. However, it is a burden for the user to select the analysis results corresponding to the molding conditions of the item to be adjusted from multiple analysis results.

[0020] Therefore, the problem to be solved by the present disclosure is to cause the display unit to display an analysis result corresponding to the molding conditions of each item by a simple operation of the user.

[0021] 〔First Embodiment〕

[0022] [Outline of Resin Flow Analysis Result Display System]

[0023] Figure 1 is a block diagram of a resin flow analysis result display system 10. The resin flow analysis result display system 10 includes an input unit 12, a display control unit 14, and a display unit 16. The resin flow analysis result display system 10 is connected to a resin flow analysis device 18 and an injection molding machine 20 via a network.

[0024] In the resin flow analysis device 18, the following information is managed in time series as an analysis result. This information is time, screw position, injection speed, pressure, and three-dimensional analysis data. Figure 2 is a table showing an example of time, screw position, injection speed, pressure, and three-dimensional analysis data managed by the resin flow analysis device 18.

[0025] The resin flow analysis device 18 arranges a plurality of points in a virtual three-dimensional space. Each point has three-dimensional coordinate values. The resin flow analysis device 18 calculates the state of the resin at each point at regular intervals during the analytically determined molding time. The state of the resin refers to the pressure, speed, temperature, and density of the resin. The state of the resin at each point, together with the three-dimensional coordinate values of each point, is managed as Figure 2 the three-dimensional analysis data shown.

[0026] The above-mentioned molding time refers to the elapsed time based on the time point when the screw starts to move in the injection process after the metering process is completed. The above-mentioned analytically determined molding time refers to the molding time calculated in the resin flow analysis device 18. Hereinafter, the analytically determined molding time may sometimes be referred to as virtual molding time. The virtual molding time corresponds to Figure 2 the time shown.

[0027] The display control unit 14 of the resin flow analysis result display system 10 acquires the analysis result from the resin flow analysis device 18. The display control unit 14 causes the three-dimensional display 22 of the analysis result to be displayed on the display unit 16 based on the three-dimensional analysis data at each time point during the virtual molding time. Figure 3 is a diagram showing a display example of the three-dimensional display 22 at a certain time point during the virtual molding time.

[0028] The display control unit 14 generates a three-dimensional display 22 by displaying, at each time point during the virtual molding time, each point existing at the boundary between the resin and substances other than the resin as polygons. Substances other than the resin refer to molds, air, etc. In Figure 3 In the display example of the three-dimensional display 22 shown, the flow path inside the mold is depicted by wireframes. The inflow range of the resin is represented by polygons within the flow path. In addition, the temperature distribution of the resin is represented by the shade of color on the polygons representing the inflow range of the resin. The temperature distribution of the resin can also be represented by color matching instead of the shade of color. In addition, instead of displaying the temperature distribution, the pressure distribution, density distribution, etc. can be displayed.

[0029] As Figure 2 shown, the screw position changes according to each time point of the virtual molding time. Therefore, it can also be said that the three-dimensional analysis data corresponds to the screw position. In addition, Figure 2 the screw position shown is the analytical screw position. The analytical screw position is the screw position obtained as the result of analysis in the resin flow analysis device 18. Hereinafter, the analytical screw position may sometimes be referred to as the virtual screw position.

[0030] The resin flow analysis device 18 calculates the molding conditions set for the injection molding machine 20. The injection molding machine 20 performs actual molding based on the molding conditions calculated in the resin flow analysis device 18. Through this actual molding, a molded product and actual molding results are obtained. The actual molding results refer to the detection values detected by various sensors provided in the injection molding machine 20 during actual molding. As the actual molding results, the screw position, injection pressure, injection speed, etc. at each time point of the molding time in actual molding are obtained. The molding time in actual molding refers to the actual elapsed time based on the time point when the screw starts to move in the injection process of actual molding. Hereinafter, the molding time in actual molding may sometimes be referred to as the actual molding time. And, the screw position obtained as the actual molding result may sometimes be referred to as the actual screw position.

[0031] The display control unit 14 controls the display unit 16 to cause the display unit 16 to display the molding conditions set for the injection molding machine 20 and the three-dimensional display 22 of the analysis results. Figure 4 And Figure 5 is a diagram showing a display example of the display unit 16. The display unit 16 has a first display area 24 and a second display area 26. The molding conditions set for the injection molding machine 20 are displayed in the first display area 24. The three-dimensional display 22 is displayed in the second display area 26.

[0032] Multiple items of molding conditions are displayed in the first display area 24. The user can select the molding conditions of one item by operating the input unit 12. The three-dimensional display 22 of the analysis results corresponding to the selected item of molding conditions is displayed in the second display area 26.

[0033] Figure 4 The item indicated by “A” in the figure represents the screw position for switching the injection speed of the second stage and the injection speed of the third stage, that is, the injection switching position. For example, when the user selects the Figure 4 molding conditions of the item indicated by “A” in the figure, the three-dimensional display 22 corresponding to the molding condition “10.00 mm” of the injection switching position is displayed in the second display area 26.

[0034] Figure 5 The item indicated by “E” in the figure represents the injection pressure for switching from the injection process to the holding pressure process, that is, the injection holding pressure switching pressure. For example, when the user selects the Figure 5 molding conditions of the item indicated by “E” in the figure, the three-dimensional display 22 corresponding to the molding condition “1.2 MPa” of the injection holding pressure switching pressure is displayed in the second display area 26.

[0035] By operating the input unit 12, the user can select items such as the injection holding pressure switching position, the maximum injection time, the holding pressure, the holding time, the maximum injection pressure, and the injection speed, in addition to the above-mentioned injection switching position and injection holding pressure switching pressure.

[0036] The injection holding pressure switching position refers to the screw position for switching from the injection process to the holding pressure process. The maximum injection time refers to the maximum time of the injection process. When the elapsed time from the start of the injection process reaches the maximum injection time, the process transfers to the holding pressure process. The holding pressure refers to the injection pressure maintained in the holding pressure process. The holding time refers to the time for maintaining the holding pressure in the holding pressure process. The maximum injection pressure refers to the maximum value of the injection pressure in the injection process. The screw moves in a manner that does not exceed this maximum injection pressure. The injection speed refers to the moving speed of the screw in the injection process.

[0037] [Structure of the display control unit]

[0038] As Figure 1 shown, the display control unit 14 includes an arithmetic unit 28 and a storage unit 30.

[0039] The arithmetic unit 28 is, for example, a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). The arithmetic unit 28 includes a molding condition acquisition unit 32, a molding condition display control unit 34, a molding condition selection unit 36, an analysis result acquisition unit 38, an actual molding result acquisition unit 40, an analysis result selection unit 42, and an analysis result display control unit 44. The molding condition acquisition unit 32, the molding condition display control unit 34, the molding condition selection unit 36, the analysis result acquisition unit 38, the actual molding result acquisition unit 40, the analysis result selection unit 42, and the analysis result display control unit 44 are implemented by the arithmetic unit 28 executing a program stored in the storage unit 30. At least a part of the molding condition acquisition unit 32, the molding condition display control unit 34, the molding condition selection unit 36, the analysis result acquisition unit 38, the actual molding result acquisition unit 40, the analysis result selection unit 42, and the analysis result display control unit 44 may also be implemented by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). At least a part of the molding condition acquisition unit 32, the molding condition display control unit 34, the molding condition selection unit 36, the analysis result acquisition unit 38, the actual molding result acquisition unit 40, the analysis result selection unit 42, and the analysis result display control unit 44 may also be implemented by an electronic circuit including discrete devices.

[0040] The storage unit 30 is composed of a volatile memory (not shown) and a non-volatile memory (not shown). The volatile memory and the non-volatile memory are computer-readable storage media. The volatile memory is, for example, a RAM (Random Access Memory) or the like. The non-volatile memory is, for example, a ROM (Read Only Memory), a flash memory, or the like. Data and the like are stored in the volatile memory, for example. Programs, tables, maps, etc. are stored in the non-volatile memory, for example. At least a part of the storage unit 30 may also be provided in the above-mentioned processor, integrated circuit, etc.

[0041] The molding condition acquisition unit 32 acquires the molding conditions of each item set for the injection molding machine 20 from the injection molding machine 20.

[0042] The molding condition display control unit 34 controls the display unit 16 to cause the acquired molding conditions of each item to be displayed in the first display area 24 as shown in Figure 4 or Figure 5 the figure.

[0043] The molding condition selection unit 36 selects one item of the molding conditions of multiple items set for the injection molding machine 20 according to the operation of the input unit 12 by the user. The input unit 12 is, for example, a touch panel provided on the screen of the display unit 16. In this case, the molding condition selection unit 36 selects the molding condition of the item displayed at the position on the screen of the display unit 16 where the user has performed a double-tap operation.

[0044] The analysis result acquisition unit 38 acquires from the resin flow analysis device 18 Figure 2 the analysis result shown.

[0045] The actual molding result acquisition unit 40 acquires the actual molding result from the injection molding machine 20. The actual molding result refers to the screw position (actual screw position), injection pressure, injection speed, etc. at each time point of the actual molding time.

[0046] The analysis result selection unit 42 selects one analysis result according to the molding condition of the item selected by the user. The selection process of the analysis result performed in the analysis result selection unit 42 will be described in detail later.

[0047] The analysis result display control unit 44 controls the display unit 16 so that Figure 4 or Figure 5 as shown, the three-dimensional display 22 of the selected analysis result is displayed in the second display area 26. The analysis result display control unit 44 corresponds to the display control unit of the present invention.

[0048] The resin flow analysis result display system 10 may also be entirely mounted on the injection molding machine 20.

[0049] The resin flow analysis result display system 10 may also be composed of multiple devices respectively connected through a network. For example, the input unit 12, the display control unit 14, and the display unit 16 may also be respectively provided on different devices.

[0050] In addition, at least a part of the storage unit 30 of the display control unit 14 may also be mounted on a device connected to the display control unit 14 through a network.

[0051] Moreover, the molding condition acquisition unit 32, the molding condition display control unit 34, the molding condition selection unit 36, the analysis result acquisition unit 38, the actual molding result acquisition unit 40, and the analysis result selection unit 42 may also be implemented by arithmetic units respectively provided on different devices.

[0052] [Selection process of analysis result]

[0053] The selection process of the analysis result performed in the analysis result selection unit 42 will be described. The selection process of the analysis result is roughly divided into two processes.

[0054] In the first process, the analysis result selection unit 42 obtains the actual screw position (actual screw position) during actual molding based on the molding conditions of the item selected by the user. In the subsequent second process, the analysis result selection unit 42 obtains the analytical screw position (virtual screw position) corresponding to the actual screw position. After completing the first process and the second process, the analysis result selection unit 42 selects the analysis result corresponding to the obtained virtual screw position according to the table shown in Figure 2 as shown.

[0055] (Regarding the first process)

[0056] Figure 6 is a graph showing the change of the molding conditions with respect to the actual screw position and the change of the actual molding result with respect to the actual screw position. Figure 6 The molding conditions shown in Figure 4 are the molding conditions of each item shown in the first display area 24 of

[0057] In Figure 4 the shown molding conditions, a three-stage injection speed is set in the injection process. In addition, in the holding pressure process, two-stage holding pressures are set. The switching from the injection process to the holding pressure process is specified by the screw position.

[0058] Figure 4 In Figure 6 the item indicated by "A" represents the screw position for switching the second-stage injection speed and the third-stage injection speed, that is, the injection switching position. When the molding conditions of this item are selected, the actual screw position (10 mm) indicated by "A" in

[0059] Figure 4 is obtained in the analysis result selection unit 42. Figure 6 In

[0060] Figure 4 the item indicated by "B" represents the holding pressure time for maintaining the second-stage holding pressure, that is, the holding pressure time. When the molding conditions of this item are selected, the actual screw position indicated by "B" in Figure 6 is obtained in the analysis result selection unit 42. This actual screw position is the position after 0.2 s of holding pressure time from when the actual screw position reaches 5 mm.

[0061] Figure 4 In Figure 6The actual screw position (10 mm) shown as “D”.

[0062] Figure 7 It is a graph showing the change of molding conditions with respect to the actual screw position and the change of actual molding results with respect to the actual screw position. Figure 7 The molding conditions shown Figure 5 are the molding conditions of each item shown in the first display area 24 of

[0063] In Figure 5 the shown molding conditions, a three-stage injection speed is set in the injection process. In addition, in the holding pressure process, a two-stage holding pressure is set. The switching from the injection process to the holding pressure process is specified by the injection pressure.

[0064] Figure 5 The item shown as “E” in Figure 6 represents the injection pressure for switching from the injection process to the holding pressure process, that is, the injection holding pressure switching pressure. When the molding conditions of this item are selected, in the analysis result selection unit 42,

[0065] the actual screw position shown as “E” in

[0066] (Regarding the second process)

[0067] In the second process, the analysis result selection unit 42 obtains the virtual screw position corresponding to the actual screw position. As methods for obtaining the virtual screw position corresponding to the actual screw position, two methods are described below. The first method is used when the stroke length of the screw in actual molding is different from the stroke length of the screw in the analysis. The second method is used when the injection start positions in actual molding and in the analysis are different although the stroke lengths are equal. In addition, the stroke length represents the length from the injection start position of the screw to the minimum cushion.

[0068] Figure 8 is a schematic diagram showing the state when the stroke length S1 of the screw in actual molding is different from the stroke length T1 of the screw in the analysis. In this case, the virtual screw position Q1 corresponding to the actual screw position P1 is obtained by the following formula.

[0069] Q1 = P1 × S1 / T1

[0070] Figure 9It is a schematic diagram showing a state where, although the stroke lengths are equal, the injection start position P0 in actual molding is different from the injection start position Q0 in analysis. In this case, the virtual screw position Q2 corresponding to the actual screw position P2 is obtained by the following formula.

[0071] Q2 = P2 + (Q0 - P0)

[0072] In the above, the process of the analysis result selection unit 42 for obtaining the virtual screw position based on the actual screw position has been described. However, the process of obtaining the virtual molding time based on the actual molding time is also carried out in the same way.

[0073] [Function and effect]

[0074] In the resin flow analysis result display system 10 of the present embodiment, the analysis result acquisition unit 38 acquires the analysis result corresponding to the virtual molding time or the virtual screw position. The molding condition selection unit 36 acquires the molding conditions of one item selected by the user. The analysis result selection unit 42 selects the analysis result according to the molding conditions of the selected item. The analysis result display control unit 44 causes the three-dimensional display 22 of the selected analysis result to be displayed on the display unit 16. Thus, by only the user operating to select the item of the molding conditions, the three-dimensional display 22 of the analysis result corresponding to the molding conditions of the selected item is displayed on the display unit 16. As a result, the resin flow analysis result display system 10 can reduce the burden on the user for the molding condition adjustment operation.

[0075] In the resin flow analysis result display system 10 of the present embodiment, the analysis result selection unit 42 obtains the actual screw position according to the molding conditions of the selected item. The analysis result selection unit 42 calculates the virtual screw position corresponding to the obtained actual screw position. The analysis result selection unit 42 selects the analysis result corresponding to the calculated virtual screw position. Thus, even when the actual screw position and the virtual screw position do not match, the resin flow analysis result display system 10 can cause the display unit 16 to display the three-dimensional display 22 of the analysis result corresponding to the molding conditions of the selected item.

[0076] 〔Modification example〕

[0077] In the resin flow analysis result display system 10 of the first embodiment, the user selects the molding conditions of one item by operating the input unit 12. In contrast, it may be set that the user can select the molding conditions of two or more items. In this case, the three-dimensional displays 22 of a plurality of analysis results are displayed in the second display area 26 of the display unit 16.

[0078] In the resin flow analysis result display system 10 of the first embodiment, the display control unit 14 causes the second display area 26 of the display unit 16 to display the three-dimensional display 22 of the analysis result. The display mode of the analysis result displayed in the second display area 26 of the display unit 16 may also be other modes.

[0079] The display control unit 14 may also, based on Figure 2 the injection speed, screw position, and injection pressure at each time point in the virtual molding time shown, cause the display unit 16 to display the chart display 50 of the analysis result. Figure 10 FIG. is a display example of the chart display 50 at a certain time point in the virtual molding time. The chart display 50 represents the change in injection speed with respect to the screw position and the change in injection pressure with respect to the screw position. In the chart display 50, a position display 52 indicating the screw position corresponding to a certain time point in the virtual molding time is displayed.

[0080] The display control unit 14 may also, based on Figure 2 the injection speed, screw position, injection pressure, and three-dimensional analysis data at each time point in the virtual molding time shown, cause the table display 54 of the analysis result to be displayed on the display unit 16. Figure 11 FIG. is a display example of the table display 54 at a certain time point in the virtual molding time. The table display 54 displays the injection speed, screw position, injection pressure, and three-dimensional analysis data at each time point in tabular form. In the table display 54, the frame of the column corresponding to a certain time point in the virtual molding time is indicated by a thick line.
