[0007] By simultaneously displaying the actual molding results obtained during actual molding using an injection molding machine and the analysis results obtained during resin flow analysis on the display unit, the user can easily change molding conditions, etc., while comparing the actual molding results with the analysis results.

[0008] In the past, the actual molding results and analysis results, where the injection time in the actual molding and the injection time in the resin flow analysis matched, were displayed simultaneously on the display unit. However, even if the injection times were the same, the amount of resin injected in the actual molding and the amount of resin injected in the resin flow analysis often differed. This resulted in a large discrepancy between the flow conditions of the resin in the mold during the actual molding and the flow conditions of the resin in the mold during the resin flow analysis.

[0009] The objective of the present disclosure is to display the actual molding results and analysis results on a display unit when there is little discrepancy between the flow conditions of resin in a mold during actual molding and the flow conditions of resin in a mold during resin flow analysis.

[0010] 1 is a block diagram of a resin flow analysis result display device 10. The resin flow analysis result display device 10 has a calculation unit 12 and a storage unit 14.

[0011] The calculation unit 12 is a processor such as a central processing unit (CPU) or a graphics processing unit (GPU). The calculation unit 12 has 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 calculation 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 application specific integrated circuit (ASIC) or a field-programmable gate array (FPGA). At least a portion 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 electronic circuits including discrete devices.

[0012] The memory unit 14 is composed of a volatile memory (not shown) and a non-volatile memory (not shown), which are computer-readable storage media. The volatile memory is, for example, a random access memory (RAM). The non-volatile memory is, for example, a read-only memory (ROM) or a flash memory. Data, for example, is stored in the volatile memory. Programs, tables, maps, for example, are stored in the non-volatile memory. At least a portion of the memory unit 14 may be provided in the above-mentioned processor, integrated circuit, etc. At least a portion of the memory unit 14 may be mounted on a device connected to the resin flow analysis result display device 10 via a network.

[0013] 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. Based on the screw diameter and the screw position at each time point acquired by the actual molding result acquisition unit 22 (described later), the amount of resin injected into the mold at each time point (injection amount) can be calculated.

[0014] The sensor signal acquisition unit 20 acquires signals from sensors provided in the mold from the injection molding machine 18. The mold is provided with multiple sensors along the flow path through which the resin flows. The sensors include, for example, pressure sensors, temperature sensors, and flow rate sensors. The injection amount can be calculated based on the signals from each sensor.

[0015] 2 is a schematic diagram of a flow path in a mold and sensors provided in the flow path. Here, sensors A, B, C, and D are provided along the flow path. When each sensor detects resin, the signal it outputs changes. By monitoring the signal from each sensor, it is possible to determine whether or not the resin has reached the position where each sensor is provided.

[0016] 3 is a table showing the relationship between each sensor and the injection amount at the time when the resin reaches the position where each sensor is installed. The volume of the flow path from the resin inlet of the mold to the position where each sensor is installed can be calculated in advance. Therefore, as shown in FIG. 3, the injection amount at the time when the resin reaches the position where each sensor is installed can be set.

[0017] The actual molding result acquisition unit 22 acquires actual molding results at each time point from the injection molding machine 18. The actual molding results are detection values ​​detected by each sensor provided in the injection molding machine 18 when the injection molding machine 18 actually performs molding. The actual molding results may include calculated values ​​obtained based on the detection values ​​of each sensor. The actual molding result acquisition unit 22 acquires, for example, injection pressure, injection speed, screw position, etc. as the actual molding results. The injection molding machine 18 collects the actual molding results at a predetermined cycle during actual molding. The predetermined cycle is, for example, 0.001 [s].

[0018] In the present disclosure, the actual molding result does not indicate a change in a value during the period in which the actual molding is performed, but indicates a value at each point in time during the period in which the actual molding is performed. Figure 4 is a graph showing the relationship between the injection time and the injection pressure during the actual molding. In the example shown in Figure 4, the actual molding result is, for example, the injection pressure Qx [MPa] during the injection time Tx [s].

[0019] In this disclosure, the change in numerical value during the period in which actual molding is performed is referred to as the change in actual molding result. In the example shown in Figure 4, the change in injection pressure from time T0 [s] at the start of injection to time Tm [s] at the end of molding is shown as a graph. In the example shown in Figure 4, the injection time is set on the horizontal axis, but other items such as screw position may also be set.

[0020] The analysis result acquisition unit 24 acquires the analysis results at each time point from the resin flow analysis device 26 .

[0021] The resin flow analysis device 26 performs resin flow analysis based on the molding conditions. The resin flow analysis device 26 calculates the injection amount, injection pressure, injection speed, screw position, etc. for each predetermined cycle. The resin flow analysis device 26 calculates the flow state of the resin inside the mold for each predetermined cycle based on the calculated injection amount, injection pressure, injection speed, screw position, etc. The predetermined cycle is, for example, 0.001 [s].

[0022] The resin flow analysis device 26 generates a three-dimensional image showing the flow state of the resin at each time point. FIG. 5 is a three-dimensional image showing the flow state of the resin at a certain time point. As the flow state of the resin, the position of the leading edge (melt front) of the resin filled inside the mold is calculated. As the flow state of the resin, the temperature distribution, pressure distribution, etc. of the resin filled inside the mold are also calculated. The three-dimensional image shown in FIG. 5 displays the flow path and the resin inflow range, and the temperature distribution of the resin is indicated by the density of dots on the display of the resin. Instead of displaying the temperature distribution, the pressure distribution may be displayed.

[0023] The analysis result acquisition unit 24 acquires a three-dimensional image as the analysis result. The analysis result acquisition unit 24 acquires, as the analysis result, not only the three-dimensional image but also the injection amount, injection pressure, injection speed, screw position, etc. in the resin flow analysis.

[0024] In this disclosure, the analysis results for the injection amount, injection pressure, injection speed, screw position, etc. do not indicate the change in values ​​during the molding period in the resin flow analysis, but indicate the values ​​at each point in time during the molding period. Figure 6 is a graph showing the relationship between injection time and injection pressure calculated in the resin flow analysis. In the example shown in Figure 6, the analysis result is, for example, the injection pressure Qu [MPa] during the injection time Tu [s].

[0025] In this disclosure, changes in the values ​​calculated in the resin flow analysis are referred to as changes in the analysis results. In the example shown in Figure 6, the change in injection pressure from time T0 [s] at the start of injection to time Tn [s] at the end of molding is shown as a graph. In the example shown in Figure 6, the injection time is set on the horizontal axis, but other items such as the screw position may also be set.

[0026] The relationship setting unit 28 associates the analysis results with the actual molding results in which the injection amount of resin in the actual molding and the injection amount of resin in the resin flow analysis match. The association between the actual molding results and the analysis results will be described in detail later.

[0027] The display control unit 30 controls the display unit 32 based on the information relating the actual molding results and the analysis results set in the relationship setting unit 28 and the information input from the input unit 34, to display the correlated actual molding results and analysis results on the display unit 32. The input unit 34 is a keyboard, a pointing device, a touch panel, etc. The display mode on the display unit 32 will be described in detail later.

[0028] [Regarding the Relationship Between Actual Molding Results and Analysis Results] FIG. 7 is a diagram for explaining the relationship between actual molding results and analysis results.

[0029] The actual molding result acquisition unit 22 acquires the actual molding results corresponding to each point in the injection time shown in the table in the upper left of Fig. 7. The injection amount of the actual molding results may be calculated based on the screw diameter and screw position. The injection amount may also be calculated based on signals output by each sensor in the mold.

[0030] The analysis result acquisition unit 24 acquires the analysis results corresponding to each point in the injection time shown in the table in the upper right corner of FIG.

[0031] The relationship setting unit 28 correlates the analysis results with the actual molding results in which the injection amounts of resin match. For example, as shown in the table at the bottom of Fig. 7, the injection time Tx [s], screw position Px [mm], injection pressure Qx [MPa], and injection speed Vx [mm / s] of the actual molding results in which the injection amount is Ax [cc] are correlated with the injection time Tu [s], screw position Pu [mm], injection pressure Qu [MPa], injection speed Vu [mm / s], and three-dimensional image Fu of the analysis results.

[0032] [Display Modes of Actual Molding Results and Analysis Results] Hereinafter, a first mode and a second mode of displaying the actual molding results and analysis results on the display unit 32 will be described.

[0033] 8 is a diagram showing a first mode of displaying actual molding results and analysis results. The display control unit 30 displays the actual molding results at a predetermined injection time and the analysis results associated with the actual molding results on the display unit 32. In FIG. 8, the left side shows a display indicating the actual molding results, and the right side shows a display indicating the analysis results.

[0034] The actual molding result is displayed on an actual molding result graph 36 that shows the change in injection pressure versus injection time. If the input unit 34 is a pointing device such as a mouse, the user operates a mouse cursor 38 using the input unit 34 to drag a position display bar 40 displayed on the actual molding result graph 36. This allows the user to select any injection time in actual molding as the predetermined injection time. If the input unit 34 is a touch panel provided on the display unit 32, the user may drag the position display bar 40 displayed on the actual molding result graph 36 by moving a finger, a stylus, or the like on the screen of the display unit 32.

[0035] When the user selects the injection time Tx [s] by moving the position display bar 40, 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, as shown in Fig. 8. Also, "Qx", which is the numerical value of the injection pressure, is displayed near the point S1. Furthermore, "Tx", which is the numerical value of the selected injection time, is displayed near the position display bar 40. When the user selects the injection time Tx [s] by moving the position display bar 40, it can also be said that the user is selecting the injection pressure Qx [MPa], which is the actual molding result.

[0036] When the user selects the injection time Tx [s] by moving the position display bar 40 on the actual molding result graph 36, a three-dimensional image Fu is displayed as the analysis result, as shown in Fig. 8. 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.

[0037] A position display slider 42 is displayed below the three-dimensional image Fu. The three-dimensional image Fu in FIG. 8 is an analysis result corresponding to the injection time Tu [s] in the resin flow analysis. The position display slider 42 indicates the position of the injection time Tu [s] relative to the total 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 graph 36. Near the position display slider 42, "Tu", which is the numerical value of the injection time corresponding to the three-dimensional image Fu, is displayed. The position display slider 42 is not limited to displaying the injection time Tu [s] corresponding to the three-dimensional image Fu, but may also display the screw position Pu [mm] corresponding to the three-dimensional image Fu, the injection amount Ax [cc] corresponding to the three-dimensional image Fu, etc.

[0038] The injection amount at injection time Tx [s] in actual molding and the injection amount at injection time Tu [s] in resin flow analysis are both Ax [cc].

[0039] The user can select any injection time in the resin flow analysis by operating the mouse cursor 38 on the input unit 34 and dragging the position display slider 42. Selecting an injection time in the resin flow analysis can also be considered as selecting a three-dimensional image, which is the analysis result. 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.

[0040] 9 is a diagram showing a second mode of displaying actual molding results and analysis results. The display control unit 30 displays the actual molding results at a predetermined injection time and the analysis results associated with the actual molding results on the display unit 32. In FIG. 9, the left side shows a display indicating the actual molding results, and the right side shows a display indicating the analysis results.

[0041] The actual molding results are displayed on an actual molding result graph 36 which shows the change in injection pressure with respect to injection time. The display mode of the actual molding results is the same as the first mode.

[0042] The analysis results are displayed on an analysis result graph 44 that shows the change in injection pressure with respect to injection time.

[0043] When the user selects the injection time Tx [s] by moving the position display bar 40 on the actual molding result graph 36, a point S2 indicating the injection pressure Qu [MPa] is displayed, as shown in Fig. 9. Also, "Qu", which is the numerical value of the injection pressure, is displayed near the point S2. The injection pressure Qu [MPa] is an analysis result related to the injection pressure Qx [MPa], which is the actual molding result selected by the user.

[0044] A position display bar 46 is displayed on the analysis result graph 44. The injection pressure Qu [MPa] in FIG. 9 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 injection time Tu [s] relative to the total 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 graph 36. "Tu," which is the numerical value of the injection time corresponding to the injection pressure Qu [MPa], is displayed near the position display bar 46.

[0045] The user can also select any injection time in the resin flow analysis by operating the mouse cursor 38 on the input unit 34 and dragging the position display bar 46. Selecting the injection time in the resin flow analysis can also be considered as selecting the analysis result. As a result, the selected analysis result and the actual molding result associated with the selected analysis result are displayed on the display unit 32.

[0046] [Modifications of actual molding result graph and analysis result graph] In the examples shown in Figures 8 and 9, the actual molding result graph 36 and the analysis result graph 44 are also shown as graphs showing changes in injection pressure with respect to injection time. The actual molding result graph 36 and the analysis result graph 44 may be graphs showing changes in items different from those shown in Figures 8 and 9.

Furthermore, a point S2 indicating the injection pressure Qu [MPa] related to the injection pressure Qx [MPa], which is the actual molding result, is displayed on the analysis result graph 44 as the analysis result. Furthermore, a position display bar 40 is displayed on the actual molding result graph 36 at the position of the injection amount Ax [cc] selected by the user. Furthermore, a position display bar 46 is displayed on the analysis result graph 44 at the position of the injection amount Ax [cc] corresponding to the injection pressure Qu [MPa], which is the analysis result.

[0049] In the example shown in Fig. 11, both the actual molding result graph 36 and the analysis result graph 44 are graphs showing changes in injection pressure with respect to screw position.

[0050] In the example shown in FIG. 12, the actual molding result graph 36 is a graph showing the change in injection pressure versus injection time. Meanwhile, the analysis result graph 44 is a graph showing the change in injection pressure versus injection amount.

Furthermore, a position indicator bar 46 is displayed on the analysis result graph 44 at the position of the injection amount Ax [cc] corresponding to the injection pressure Qu [MPa], which is the analysis result.

[0051] In the example shown in Fig. 13, the actual molding result graph 36 is a graph showing the change in injection pressure with respect to injection time. On the other hand, the analysis result graph 44 is a graph showing the change in injection speed with respect to injection time. In the example shown in Fig. 13, a point S1 indicating the injection pressure Qx [MPa] corresponding to the injection time Tx [s] selected by the user is displayed on the actual molding result graph 36 as the actual molding result. Furthermore, a point S2 indicating the injection speed Vu [mm / s] related to the injection pressure Qx [MPa], which is the actual molding result, is displayed on the analysis result graph 44 as the analysis result. Furthermore, a position display bar 40 is displayed on the actual molding result graph 36 at the position of the injection time Tx [s] selected by the user. Furthermore, a position display bar 46 is displayed on the analysis result graph 44 at the position of the injection time Tu [s] corresponding to the injection speed Vu [mm / s], which is the analysis result.

[0052] In the example shown in FIG. 14 , the actual molding result graph 36 is a graph showing the change in injection pressure versus injection time. Meanwhile, the analysis result graph 44 is a graph showing the change in injection speed versus injection amount. In the example shown in FIG. 14 , a point S1 indicating the injection pressure Qx [MPa] corresponding to the injection time Tx [s] selected by the user is displayed on the actual molding result graph 36 as the actual molding result. Furthermore, a point S2 indicating the injection speed Vu [mm / s] associated with the injection pressure Qx [MPa], which is the actual molding result, is displayed on the analysis result graph 44 as the analysis result.

Furthermore, a position indicator bar 46 is displayed on the analysis result graph 44 at the position of the injection amount Ax [cc] corresponding to the injection speed Vu [mm / s], which is the analysis result.

[0053] The actual forming result graph 36 shown in Figures 8 to 14 displays one graph as the actual forming result. However, the actual forming result graph 36 may display two or more graphs as the actual forming result. Furthermore, the analysis result graph 44 shown in Figures 9 to 14 displays one graph as the analysis result. However, the analysis result graph 44 may display two or more graphs as the analysis result.
