[0024] By simultaneously displaying the actual molding results obtained in actual molding by the injection molding machine and the analysis results obtained in the resin flow analysis on the display unit, the user can easily change the molding conditions while comparing the actual molding results and the analysis results.

[0025] Conventionally, the actual molding result and the analysis result are displayed on the display unit at the same time when the injection time in the actual molding is consistent with the injection time in the resin flow analysis. However, even if the injection time is the same, the injection amount of the resin in the actual molding and the injection amount of the resin in the resin flow analysis are often different. Therefore, there is a large deviation between the flow state of the resin in the metal mold in the actual molding and the flow state of the resin in the metal mold in the resin flow analysis.

[0026] An object of the present disclosure is to display the actual molding result and the analysis result on a display unit in a state where the difference between the flow state of the resin in the mold during actual molding and the flow state of the resin in the mold during resin flow analysis is small.

[0027] [First embodiment]

[0028] [Structure of the resin flow analysis result display device]

[0029] Figure 1 2 is a block diagram of the resin flow analysis result display device 10 . The resin flow analysis result display device 10 includes a calculation unit 12 and a storage unit 14 .

[0030] The computing unit 12 is, for example, a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). The computing unit 12 includes a molding machine information acquisition unit 16, a sensor signal acquisition unit 20, an actual molding result acquisition unit 22, an analysis result acquisition unit 24, a relationship setting unit 28, and a display control unit 30. The molding machine information acquisition unit 16, the sensor signal acquisition unit 20, the actual molding result acquisition unit 22, the analysis result acquisition unit 24, the relationship setting unit 28, and the display control unit 30 are realized by the computing unit 12 executing a program stored in the storage unit 14. At least a part of the molding machine information acquisition unit 16, the sensor signal acquisition unit 20, the actual molding result acquisition unit 22, the analysis result acquisition unit 24, the relationship setting unit 28, and the display control unit 30 may be realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). At least part of the molding machine information acquisition unit 16 , the sensor signal acquisition unit 20 , the actual molding result acquisition unit 22 , the analysis result acquisition unit 24 , the relationship setting unit 28 , and the display control unit 30 may be realized by an electronic circuit including discrete devices.

[0031] The storage unit 14 is composed of a volatile memory (not shown) and a non-volatile memory (not shown) as a computer-readable storage medium. Examples of volatile memory include RAM (Random Access Memory) and the like. Examples of non-volatile memory include ROM (Read Only Memory), flash memory and the like. Data and the like are stored in volatile memory, for example. Programs, tables, mappings and the like are stored in non-volatile memory, for example. At least a portion of the storage unit 14 may also be provided in the above-mentioned processor, integrated circuit and the like. At least a portion of the storage unit 14 may also be mounted on a device connected to the resin flow analysis result display device 10 via a network.

[0032] The molding machine information acquisition unit 16 acquires information on the specifications of the injection molding machine 18 from the injection molding machine 18. The specifications of the injection molding machine 18 include, for example, the screw diameter, etc. The amount of resin injected into the metal mold at each time point (injection amount) can be obtained based on the screw diameter and the screw position at each time point acquired in the actual molding result acquisition unit 22 described later.

[0033] The sensor signal acquisition unit 20 acquires the signal of the sensor provided in the metal mold from the injection molding machine 18. A plurality of sensors are provided in the metal mold along the flow path of the resin flow. The sensor is, for example, a pressure sensor, a temperature sensor, a flow rate sensor, etc. The injection volume can be obtained based on the signal of each sensor.

[0034] Figure 2 This is a schematic diagram of the flow path in the metal mold and the sensors installed in the flow path. Here, sensors A, B, C, and D are installed along the flow path. When each sensor detects resin, the signal output by each sensor changes. By monitoring the signal of each sensor, it is possible to determine whether the resin has reached the position where each sensor is installed.

[0035] Figure 3 is a table showing the relationship between each sensor and the injection volume at the time when the resin reaches the position where each sensor is set. The volume of the flow path from the resin inlet to the position where each sensor is set in the metal mold can be calculated in advance. Figure 3 As shown, the injection amount at the time when the resin reaches the position where each sensor is installed can be set.

[0036] The actual molding result acquisition unit 22 acquires the actual molding result at each time point from the injection molding machine 18. The actual molding result refers to the detection value detected by each sensor provided in the injection molding machine 18 when the injection molding machine 18 actually performs molding. The actual molding result may also include a calculated value obtained based on the detection value of each sensor. The actual molding result acquisition unit 22 acquires, for example, injection pressure, injection speed, screw position, etc. as the actual molding result. The injection molding machine 18 collects the actual molding result at a predetermined period during actual molding. The predetermined period is, for example, 0.001 [s].

[0037] In the present disclosure, the actual molding result does not indicate changes in numerical values ​​during the period in which the actual molding is performed, but indicates numerical values ​​at each time point during the period in which the actual molding is performed. Figure 4 This is a graph showing the relationship between injection time and injection pressure in actual molding. Figure 4 In the example shown, the actual molding result is, for example, the injection pressure Qx [MPa] during the injection time Tx [s].

[0038] In this disclosure, changes in numerical values ​​during the actual molding process are described as changes in actual molding results. Figure 4 In the example shown, the change in injection pressure from time T0 [s] when injection starts to time Tm [s] when molding ends is shown as a graph. Figure 4 In the example shown, the injection time is set on the horizontal axis, but other items such as the screw position may also be set.

[0039] The analysis result acquisition unit 24 acquires the analysis results at each time point from the resin flow analysis device 26 .

[0040] The resin flow analysis device 26 performs resin flow analysis based on the molding conditions. The resin flow analysis device 26 calculates the injection volume, injection pressure, injection speed, screw position, etc. for each predetermined cycle. The resin flow analysis device 26 calculates the flow state of the resin in each predetermined cycle inside the metal mold based on the calculated injection volume, injection pressure, injection speed, screw position, etc. The predetermined cycle is, for example, 0.001 [s].

[0041] The resin flow analysis device 26 generates a three-dimensional image as the flow state of the resin at each time point. Figure 5 It is a three-dimensional image showing the flow state of the resin at a certain point in time. As the flow state of the resin, the position of the front end (melt front) of the resin filled in the metal mold is calculated. In addition, as the flow state of the resin, the temperature distribution and pressure distribution of the resin filled in the metal mold are calculated. Figure 5 The flow path and the range of the resin inflow are displayed in the stereoscopic image, and the temperature distribution of the resin is represented by the density of the dots on the display of the resin. The pressure distribution may be displayed instead of the temperature distribution.

[0042] The analysis result acquisition unit 24 acquires a three-dimensional image as an analysis result. The analysis result acquisition unit 24 acquires the injection amount, injection pressure, injection speed, screw position, etc. in resin flow analysis as analysis results in addition to the three-dimensional image.

[0043] Regarding the injection volume, injection pressure, injection speed, screw position, etc., in the present disclosure, the analysis results do not indicate changes in numerical values ​​during molding in resin flow analysis, but indicate numerical values ​​at each time point during molding. Figure 6 This is a graph showing the relationship between injection time and injection pressure calculated in resin flow analysis. Figure 6 In the example shown, the analysis result is, for example, the injection pressure Qu [MPa] at the injection time Tu [s].

[0044] In this disclosure, changes in numerical values ​​calculated in resin flow analysis are described as changes in analysis results. Figure 6 In the example shown, the change in injection pressure from time T0 [s] when injection starts to time Tn [s] when molding ends is shown as a graph. Figure 6 In the example shown, the injection time is set on the horizontal axis, but other items such as the screw position may also be set.

[0045] The relationship setting unit 28 associates the actual molding result and the analysis result in which the injection amount of the resin in the actual molding matches the injection amount of the resin in the resin flow analysis. The association between the actual molding result and the analysis result will be described in detail later.

[0046] The display control unit 30 controls the display unit 32 to display the actual molding results and the analysis results associated with each other, based on the association information between the actual molding results and the analysis results set in the relationship setting unit 28 and the information input from the input unit 34. The input unit 34 is a keyboard, a pointing device, a touch panel, etc. The display method in the display unit 32 will be described in detail later.

[0047] [About the correlation between actual molding results and analysis results]

[0048] Figure 7 This is a diagram that explains the relationship between actual molding results and analysis results.

[0049] The actual molding result acquisition unit 22 acquires Figure 7 The upper left table shows the actual molding results corresponding to each injection time point. In addition, the injection volume of the actual molding result can also be calculated based on the screw diameter and screw position. In addition, the injection volume can also be calculated based on the signals output by each sensor of the metal mold.

[0050] The analysis result acquisition unit 24 acquires Figure 7 The upper right table shows the analysis results corresponding to each injection time point.

[0051] The relationship setting unit 28 associates the actual molding result with the analysis result when the injection amount of the resin is consistent. Figure 7 As shown in the table below, for example, the injection time Tx [s], screw position Px [mm], injection pressure Qx [MPa] and injection speed Vx [mm / s] of the actual molding result with an injection volume of Ax [cc] are associated with the injection time Tu [s], screw position Pu [mm], injection pressure Qu [MPa], injection speed Vu [mm / s] and stereoscopic image Fu of the analysis result.

[0052] [About the display method of actual molding results and analysis results]

[0053] Hereinafter, a first mode and a second mode of displaying the actual molding result and the analysis result on the display unit 32 will be described.

[0054] Figure 8 1 is a diagram showing a first mode of displaying the actual molding result and the analysis result. The display control unit 30 causes the display unit 32 to display the actual molding result of a predetermined injection time and the analysis result associated with the actual molding result. Figure 8 In the figure, the left side shows the actual molding results, and the right side shows the analysis results.

[0055] The actual molding result is displayed on an actual molding result graph 36 showing the change of injection pressure with respect to injection time. When the input unit 34 is a pointing device such as a mouse, the user operates the mouse cursor 38 through the input unit 34 to drag the position display bar 40 displayed on the actual molding result graph 36. Thus, the user can select any injection time in the actual molding as the prescribed injection time. When the input unit 34 is a touch panel provided on the display unit 32, the user can also drag the position display bar 40 displayed on the actual molding result graph 36 by moving a finger, a stylus pen, etc. on the screen of the display unit 32.

[0056] When the user selects the injection time Tx[s] by moving the position display bar 40, Figure 8 As shown, a point S1 indicating the injection pressure Qx [MPa] corresponding to the injection time Tx [s] is displayed on the actual molding result graph 36. In addition, the numerical value of the injection pressure, "Qx", is displayed near the point S1. Furthermore, the numerical value of the selected injection time, "Tx", is displayed near the position display bar 40. The user can select the injection time Tx [s] by moving the position display bar 40, which can also be said to be selecting the actual molding result, namely the injection pressure Qx [MPa].

[0057] When the user selects the injection time Tx [s] by moving the position display bar 40 on the actual molding result graph 36, as shown in FIG. Figure 8 As shown in FIG. 1 , a three-dimensional image Fu is displayed as an analysis result. This three-dimensional image Fu is an image associated with the injection pressure Qx [MPa], which is the actual molding result selected by the user.

[0058] A position display slider 42 is displayed below the stereoscopic image Fu. Figure 8 The stereoscopic image Fu is the analysis result corresponding to the injection time Tu[s] in the resin flow analysis. The position display slider 42 indicates the position of the overall injection time Tu[s] relative to the injection time in the resin flow analysis. The position display slider 42 is linked to the position display bar 40 on the actual molding result chart 36. The numerical value of the injection time corresponding to the stereoscopic image Fu, i.e., "Tu", is displayed near the position display slider 42. The position display slider 42 is not limited to the injection time Tu[s] corresponding to the stereoscopic image Fu, but can also display the screw position Pu[mm] corresponding to the stereoscopic image Fu, and the injection volume Ax[cc] corresponding to the stereoscopic image Fu.

[0059] The injection amount at the injection time Tx [s] in actual molding and the injection amount at the injection time Tu [s] in resin flow analysis are both Ax [cc].

[0060] The user can also select any injection time in the resin flow analysis by operating the mouse cursor 38 through the input unit 34 and dragging the position display slider 42. Selecting the injection time in the resin flow analysis can also be said to be selecting the analysis result, that is, the three-dimensional image. As a result, the selected three-dimensional image and the actual molding result associated with the selected three-dimensional image are displayed on the display unit 32.

[0061] Fig. 9 2 is a diagram showing a second mode of displaying the actual molding result and the analysis result. The display control unit 30 causes the display unit 32 to display the actual molding result in a predetermined injection time and the analysis result associated with the actual molding result. Fig. 9 In the figure, the left side shows the actual molding results, and the right side shows the analysis results.

[0062] The actual molding result is displayed on an actual molding result graph 36 showing changes in injection pressure with respect to injection time. The display method of the actual molding result is the same as the first method.

[0063] The analysis results are displayed on an analysis result graph 44 showing changes in injection pressure with respect to injection time.

[0064] When the user selects the injection time Tx [s] by moving the position display bar 40 on the actual molding result graph 36, as shown in FIG. Fig. 9 As shown, point S2 indicating the injection pressure Qu [MPa] is displayed. Also, the numerical value of the injection pressure, “Qu”, is displayed near point S2. The injection pressure Qu [MPa] is an analysis result associated with the actual molding result selected by the user, namely the injection pressure Qx [MPa].

[0065] A position display bar 46 is displayed on the analysis result graph 44 . Fig. 9 The injection pressure Qu [MPa] is the analysis result corresponding to the injection time Tu [s] in the resin flow analysis. The position display bar 46 indicates the position of the overall injection time Tu [s] relative to the injection time in the resin flow analysis. The position display bar 46 is linked to the position display bar 40 on the actual molding result chart 36. The numerical value of the injection time corresponding to the injection pressure Qu [MPa], i.e., "Tu", is displayed near the position display bar 46.

[0066] The user can also select any injection time in the resin flow analysis by operating the mouse cursor 38 through the input unit 34 and dragging the position display bar 46. Selecting the injection time in the resin flow analysis can also be said to be selecting the analysis result. Thus, the selected analysis result and the actual molding result associated with the selected analysis result are displayed on the display unit 32.
