Description

Resin flow analysis result display system and resin flow analysis result display control method

[0001] The present disclosure relates to a resin flow analysis result display system and a resin flow analysis result display control method.

[0002] Japanese Patent Application Laid-Open No. 2002-361702 discloses a personal computer that displays the progress of the melt front on a display as a result of resin flow analysis.

[0003] When displaying the analysis results obtained in a resin flow analysis on a display unit, a better resin flow analysis result display system and resin flow analysis result display control method are desired.

[0004] A first aspect of the present disclosure is a resin flow analysis result display system having a display unit that displays analysis results obtained in resin flow analysis, and the resin flow analysis result display system has an analysis result acquisition unit that acquires the analysis results associated with each time point or each screw position in the resin flow analysis, a molding condition selection unit that selects the molding conditions for at least one item from multiple molding conditions set for an injection molding machine, an analysis result selection unit that selects the analysis results according to the molding conditions for the selected item, and a display control unit that displays the selected analysis results on the display unit.

[0005] A second aspect of the present disclosure is a resin flow analysis result display control method for displaying analysis results obtained in a resin flow analysis on a display unit, the resin flow analysis result display control method acquiring the analysis results associated with each time point or each screw position in the resin flow analysis, selecting the molding conditions for at least one item from a plurality of molding conditions set for an injection molding machine, selecting the analysis results according to the molding conditions for the selected item, and displaying the selected analysis results on the display unit.

[0006] FIG. 1 is a block diagram of a resin flow analysis result display system. FIG. 2 is a table showing examples of time, screw position, injection speed, pressure, and three-dimensional analysis data managed by a resin flow analysis device. FIG. 3 is a diagram showing an example of a three-dimensional display of analysis results. FIG. 4 is a diagram showing an example of a display on the display unit. FIG. 5 is a diagram showing an example of a display on the display unit. FIG. 6 is a graph showing changes in molding conditions relative to the actual screw position and changes in actual molding results. FIG. 7 is a graph showing changes in molding conditions relative to the actual screw position and changes in actual molding results.

FIG. 10 is a diagram showing an example of a graph display at a certain point in virtual molding time. FIG. 11 is a diagram showing an example of a table display at a certain point in virtual molding time.

[0007] A resin flow analysis device analyzes the flow state of resin in an injection molding machine and calculates the molding conditions to be set for the injection molding machine. However, a resin flow analysis device cannot completely reproduce the flow state of 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 generally not possible to obtain a good molded product in actual molding. Therefore, users must adjust the molding conditions calculated by the resin flow analysis device. The molding conditions are adjusted based on the molded product obtained in actual molding, the actual molding results, etc., and the analysis results obtained by the resin flow analysis device.

[0008] The analysis results obtained by the resin flow analysis device are displayed on the display unit. The analysis results are associated with each time point or each screw position in the analysis. The user can display the analysis results corresponding to any time point or screw position on the display unit by operating a slide bar or the like to specify the time point or screw position in the analysis.

[0009] When a user adjusts molding conditions, the user must select an analysis result that corresponds to the molding conditions of the item to be adjusted and display the selected analysis result on the display unit. However, selecting an analysis result that corresponds to the molding conditions of the item to be adjusted from among a large number of analysis results is a burden for the user.

[0010] Therefore, an object of the present disclosure is to allow the user to easily perform operations to display analysis results corresponding to the molding conditions for each item on a display unit.

[0011] 1 is a block diagram of a resin flow analysis result display system 10. The resin flow analysis result display system 10 has 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.

[0012] The resin flow analysis device 18 manages the following information in chronological order as the analysis results: time, screw position, injection speed, pressure, and three-dimensional analysis data. Fig. 2 is a table showing an example of the time, screw position, injection speed, pressure, and three-dimensional analysis data managed by the resin flow analysis device 18.

[0013] The resin flow analysis device 18 arranges multiple 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 predetermined time intervals during the analytical molding time. The state of the resin refers to the pressure, velocity, 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 three-dimensional analysis data shown in FIG. 2.

[0014] The aforementioned molding time is the elapsed time based on the time when the screw starts moving in the injection process after the metering process is completed. The aforementioned analytical molding time is the molding time calculated by the resin flow analysis device 18. Hereinafter, the analytical molding time may be referred to as the virtual molding time. The virtual molding time corresponds to the time shown in FIG. 2.

[0015] The display control unit 14 of the resin flow analysis result display system 10 acquires the analysis results from the resin flow analysis device 18. The display control unit 14 displays a three-dimensional representation 22 of the analysis results on the display unit 16 based on the three-dimensional analysis data at each time point during the virtual molding time. Fig. 3 is a diagram showing an example of the three-dimensional representation 22 at a certain time point during the virtual molding time.

[0016] The display control unit 14 generates the three-dimensional display 22 by displaying, as polygons, each point on the boundary between the resin and a substance other than the resin at each time point during the virtual molding time. The substance other than the resin indicates the mold, air, etc. In the display example of the three-dimensional display 22 shown in FIG. 3, the flow path within the mold is depicted as a wireframe. The resin inflow range is displayed as polygons within the flow path. Furthermore, the temperature distribution of the resin is displayed as shades of color on the polygons indicating the resin inflow range. The temperature distribution of the resin may be displayed as a color scheme instead of shades of color. Furthermore, instead of displaying the temperature distribution, pressure distribution, density distribution, etc. may be displayed.

[0017] As shown in Figure 2, the screw position changes depending on each point in the virtual molding time. Therefore, it can be said that the three-dimensional analysis data is associated with the screw position. The screw position shown in Figure 2 is the analytical screw position. The analytical screw position is the screw position obtained as an analysis result in the resin flow analysis device 18. Hereinafter, the analytical screw position may be referred to as the virtual screw position.

[0018] The resin flow analysis device 18 calculates the molding conditions to be set in the injection molding machine 20. The injection molding machine 20 performs actual molding based on the molding conditions calculated by the resin flow analysis device 18. This actual molding results in a molded product and actual molding results. The actual molding results are values ​​detected by various sensors provided in the injection molding machine 20 during actual molding. The actual molding results include the screw position, injection pressure, injection speed, etc. at each point in time during the molding time in actual molding. The molding time in actual molding is the actual elapsed time based on the point in time when the screw starts to move during the injection process of actual molding. Hereinafter, the molding time in actual molding may be referred to as the actual molding time. Furthermore, the screw position obtained as the actual molding result may be referred to as the actual screw position.

[0019] The display control unit 14 controls the display unit 16 to display the molding conditions set in the injection molding machine 20 and a three-dimensional representation 22 of the analysis results on the display unit 16. Figures 4 and 5 are diagrams showing examples of the display on the display unit 16. The display unit 16 has a first display area 24 and a second display area 26. The molding conditions set in the injection molding machine 20 are displayed in the first display area 24. The three-dimensional representation 22 is displayed in the second display area 26.

[0020] A plurality of molding conditions are displayed in the first display area 24. The user can select one molding condition by operating the input unit 12. A three-dimensional representation 22 of the analysis results corresponding to the selected molding condition is displayed in the second display area 26.

[0021] The item indicated by "A" in Fig. 4 indicates the injection switching position, which is the screw position at which the second-stage injection speed and the third-stage injection speed are switched. For example, when the user selects the molding condition indicated by "A" in Fig. 4, the three-dimensional display 22 corresponding to the molding condition "10.00 mm" for the injection switching position is displayed in the second display area 26.

[0022] The item indicated by "E" in Fig. 5 indicates the injection / hold pressure switching pressure, which is the injection pressure at which the injection process is switched to the hold pressure process. For example, when the user selects the molding condition indicated by "E" in Fig. 5, a three-dimensional representation 22 corresponding to the molding condition of the injection / hold pressure switching pressure of "1.2 MPa" is displayed in the second display area 26.

[0023] By operating the input unit 12, the user can select the above-mentioned injection switch position and injection hold pressure switch pressure, as well as items such as the injection hold pressure switch position, maximum injection time, hold pressure, hold pressure time, maximum injection pressure, and injection speed.

[0024] The injection / hold pressure switching position is the screw position at which the process switches from the injection process to the hold pressure process. The maximum injection time is the maximum time for the injection process. When the time elapsed since the start of the injection process reaches the maximum injection time, the process moves to the hold pressure process. The hold pressure is the injection pressure maintained in the hold pressure process. The hold pressure time is the time during which the hold pressure is maintained in the hold pressure process. The maximum injection pressure is the maximum value of the injection pressure in the injection process. The screw is moved so as not to exceed this maximum injection pressure. The injection speed is the speed at which the screw moves in the injection process.

[0025] [Configuration of Display Control Unit] As shown in FIG. 1 , the display control unit 14 includes a calculation unit 28 and a storage unit 30 .

[0026] The calculation unit 28 is a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). The calculation unit 28 has 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 realized by the calculation 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 be realized 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 be realized by an electronic circuit including a discrete device.

[0027] The storage unit 30 is composed of a volatile memory (not shown) and a nonvolatile memory (not shown). The volatile memory and the nonvolatile memory are computer-readable storage media. The volatile memory is, for example, a random access memory (RAM). The nonvolatile memory is, for example, a read-only memory (ROM), a flash memory, etc. Data, etc. are stored in the volatile memory. Programs, tables, maps, etc. are stored in the nonvolatile memory. At least a portion of the storage unit 30 may be provided in the processor, integrated circuit, etc. described above.

[0028] The molding condition acquisition unit 32 acquires, from the injection molding machine 20, molding conditions for each item set in the injection molding machine 20.

[0029] The molding condition display control unit 34 controls the display unit 16 to display the acquired molding conditions for each item in the first display area 24, as shown in FIG. 4 or FIG.

[0030] The molding condition selection unit 36 ​​selects one molding condition from among a plurality of molding conditions set in the injection molding machine 20 based on the user's operation of the input unit 12. 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 double-tapped.

[0031] The analysis result acquisition unit 38 acquires the analysis results shown in FIG. 2 from the resin flow analysis device 18 .

[0032] The actual molding result acquisition unit 40 acquires the actual molding results from the injection molding machine 20. The actual molding results include the screw position (actual screw position), injection pressure, injection speed, etc. at each point in time during the actual molding time.

[0033] The analysis result selection unit 42 selects one analysis result based on the molding conditions of the item selected by the user. The selection process of the analysis result performed by the analysis result selection unit 42 will be described in detail later.

[0034] The analysis result display control unit 44 controls the display unit 16 to display a three-dimensional representation 22 of the selected analysis result in the second display area 26, as shown in Figure 4 or 5. The analysis result display control unit 44 corresponds to the display control unit of the present invention.

[0035] The resin flow analysis result display system 10 may be entirely mounted on the injection molding machine 20 .

[0036] The resin flow analysis result display system 10 may be configured with a plurality of devices connected via a network. For example, the input unit 12, the display control unit 14, and the display unit 16 may each be provided in a separate device.

[0037] Furthermore, at least a part of the storage unit 30 of the display control unit 14 may be installed in a device connected to the display control unit 14 via a network.

[0038] Furthermore, the molding condition acquisition unit 32, molding condition display control unit 34, molding condition selection unit 36, analysis result acquisition unit 38, actual molding result acquisition unit 40 and analysis result selection unit 42 may each be realized by an arithmetic unit provided in a separate device.

[0039] [Analysis Result Selection Processing] A description will be given of the analysis result selection processing performed by the analysis result selection unit 42. The analysis result selection processing is roughly divided into two processing steps.

[0040] In the first process, the analysis result selection unit 42 determines the screw position in actual molding (actual screw position) from the molding conditions of the items selected by the user. In the subsequent second process, the analysis result selection unit 42 determines the analytical screw position (virtual screw position) corresponding to the actual screw position. After completing the first and second processes, the analysis result selection unit 42 selects the analysis result corresponding to the determined virtual screw position according to the table shown in FIG.

[0041] (Regarding the first process) Fig. 6 is a graph showing changes in molding conditions and changes in actual molding results with respect to the actual screw position. The molding conditions shown in Fig. 6 represent the molding conditions for each item shown in the first display area 24 of Fig. 4.

[0042] 4, the injection speed is set in three stages during the injection process. The holding pressure is set in two stages during the holding process. The switch from the injection process to the holding process is determined by the screw position.

[0043] The item indicated by "A" in Fig. 4 indicates the injection switching position, which is the screw position at which the second-stage injection speed and the third-stage injection speed are switched. When the molding conditions of this item are selected, the actual screw position (10 mm) indicated by "A" in Fig. 6 is obtained in the analysis result selection unit 42.

[0044] The item indicated by "B" in Fig. 4 indicates the dwell time, which is the time for which the second-stage holding pressure is maintained. When the molding conditions of this item are selected, the analysis result selection unit 42 determines the actual screw position indicated by "B" in Fig. 6. This actual screw position is the position 0.2 seconds after the actual screw position reaches 5 mm and the dwell time has elapsed.

[0045] The item indicated by "C" in Fig. 4 indicates the maximum injection pressure when the screw is advanced at the third stage injection speed. When the molding conditions of this item are selected, the analysis result selection unit 42 determines the actual screw position (10 mm) indicated by "C" in Fig. 6.

[0046] The item indicated by "D" in Fig. 4 indicates the injection speed of the third stage. When the molding conditions of this item are selected, the analysis result selection unit 42 obtains the actual screw position (10 mm) indicated by "D" in Fig. 6.

[0047] 7 is a graph showing changes in molding conditions and changes in actual molding results with respect to the actual screw position. The molding conditions shown in FIG. 7 represent the molding conditions for each item shown in the first display area 24 of FIG.

[0048] 5, the injection speed is set in three stages during the injection process. The holding pressure is set in two stages during the holding process. The switching from the injection process to the holding process is determined by the injection pressure.

[0049] The item indicated by "E" in Fig. 5 indicates the injection / hold pressure switching pressure, which is the injection pressure at which the injection process is switched to the hold pressure process. When the molding conditions of this item are selected, the analysis result selection unit 42 determines the actual screw position indicated by "E" in Fig. 6. This actual screw position is the position at the time when the injection pressure reaches the injection / hold pressure switching pressure of 1.2 MPa.

[0050] The above describes the processing of the analysis result selection unit 42 that determines the actual screw position from the molding conditions of the items selected by the user, but the processing of determining the actual molding time from the molding conditions of the items selected by the user is also performed in a similar manner.

[0051] (Regarding the second process) In the second process, the analysis result selection unit 42 determines the virtual screw position corresponding to the actual screw position. Two methods for determining the virtual screw position corresponding to the actual screw position 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 stroke lengths are the same but the injection start position in actual molding is different from the injection start position in the analysis. The stroke length refers to the length from the injection start position of the screw to the minimum cushion.

[0052] 8 is an image diagram showing a state in which the stroke length S1 of the screw in actual molding differs from the stroke length T1 of the screw in analysis. In this case, the virtual screw position Q1 corresponding to the actual screw position P1 can be calculated using the following formula:

[0053] Q1=P1×S1 / T1

[0054] 9 is an image diagram showing a state where the injection start position P0 in actual molding and the injection start position Q0 in analysis are different, even though the stroke lengths are the same. In this case, the virtual screw position Q2 corresponding to the actual screw position P2 can be calculated using the following formula.

[0055] Q2=P2+(Q0-P0)

[0056] The processing of the analysis result selection unit 42 for determining the virtual screw position from the actual screw position has been described above, but the processing for determining the virtual molding time from the actual molding time is also performed in the same way.

[0057] [Effects] In the resin flow analysis result display system 10 of this embodiment, the analysis result acquisition unit 38 acquires analysis results associated with virtual molding time or virtual screw position. The molding condition selection unit 36 ​​acquires molding conditions for one item selected by the user. The analysis result selection unit 42 selects analysis results based on the molding conditions for the selected item. The analysis result display control unit 44 displays a three-dimensional representation 22 of the selected analysis results on the display unit 16. As a result, when the user simply performs an operation to select an item of molding conditions, the three-dimensional representation 22 of the analysis results corresponding to the molding conditions for 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 of adjusting molding conditions.

[0058] In the resin flow analysis result display system 10 of this embodiment, the analysis result selection unit 42 determines the actual screw position according to the molding conditions of the selected item. The analysis result selection unit 42 calculates a virtual screw position corresponding to the determined actual screw position. The analysis result selection unit 42 selects the analysis result corresponding to the calculated virtual screw position. This allows the resin flow analysis result display system 10 to display on the display unit 16 a three-dimensional representation 22 of the analysis result according to the molding conditions of the selected item, even if the actual screw position and the virtual screw position do not match.

[0059] In the resin flow analysis result display system 10 of the first embodiment, the user selects one molding condition by operating the input unit 12. Alternatively, the user may be allowed to select two or more molding conditions. In this case, a three-dimensional representation 22 of multiple analysis results is displayed in the second display area 26 of the display unit 16.

[0060] In the resin flow analysis result display system 10 of the first embodiment, the display control unit 14 displays a three-dimensional representation 22 of the analysis results in the second display area 26 of the display unit 16. The display form of the analysis results displayed in the second display area 26 of the display unit 16 may be another form.

[0061] The display control unit 14 may cause the display unit 16 to display a graph 50 of the analysis results based on the injection speed, screw position, and injection pressure at each point in time during the virtual molding time shown in Fig. 2. Fig. 10 is a diagram showing an example of the graph 50 at a certain point in time during the virtual molding time. The graph 50 shows the change in injection speed relative to the screw position and the change in injection pressure relative to the screw position. The graph 50 displays a position indicator 52 that shows the screw position corresponding to the certain point in time during the virtual molding time.

[0062] The display control unit 14 may cause the display unit 16 to display a table display 54 of the analysis results based on the injection speed, screw position, injection pressure, and three-dimensional analysis data at each point in time during the virtual molding time shown in Fig. 2. Fig. 11 is a diagram showing an example of the table display 54 at a certain point in time during the virtual molding time. The table display 54 displays the injection speed, screw position, injection pressure, and three-dimensional analysis data at each point in time in a table format. In the table display 54, the frame of a column corresponding to a certain point in time during the virtual molding time is indicated by a thick line.
