Detailed description of the invention

[0007] A resin flow analyzer can simulate the molding of a target part and obtain a molding result from the simulation. The molding result is, for example, a change in injection pressure over time or the like.

[0008] A molding determination device determines whether the injection molding machine can mold a target molded part based on the molding result obtained by the resin flow analysis device and the specification information of an injection molding machine. If the injection molding machine's specifications can accommodate the molding result, the molding determination device determines that the injection molding machine can mold the target molded part. Conversely, if the injection molding machine's specifications cannot accommodate the molding result, the molding determination device determines that the injection molding machine cannot mold the target molded part.

[0009] The molding result obtained by the resin flow analysis device is a simulation molding result. Therefore, an error occurs between the molding result obtained by the resin flow analysis device and the molding result obtained during actual molding by the injection molding machine. Due to this error, the molding determination device may erroneously determine that the injection molding machine can mold the target molded part, even though the injection molding machine actually cannot mold the target molded part.

[0010] In a case where the production plan of the target molded part is created based on the erroneous detection, the target molded part cannot actually be molded by the injection molding machine, and the operator needs to modify the production plan.

[0011] An object of the present disclosure is to provide a shape determination device, an injection molding machine, and a shape determination method capable of improving the accuracy of a determination as to whether the injection molding machine can mold a target molded part. First embodiment

[0012] Fig. 1 is a block diagram illustrating the configuration of a molding detection device 90. The molding detection device 90 is connected to a resin flow analyzer 14 and an injection molding machine 16. Note that the molding detection device 90 may be provided in the injection molding machine 16.

[0013] The resin flow analysis device 14 detects a molding condition corresponding to each mold based on the flow analysis of the resin in the mold. Since the mold is formed for each molded part, it can be said that the molding condition is detected corresponding to each molded part.

[0014] The resin flow analysis device 14 acquires a molding result corresponding to each mold based on the flow analysis of the resin in the mold. The molding result acquired by the resin flow analysis device 14 is a molding result obtained by performing a simulation. Since the mold is formed for each molded part, it can be said that the molding result is acquired corresponding to each molded part.

[0015] The molding determination device 90 compares the molding result corresponding to a mold used for molding a target molded article with the specification of the injection molding machine 16 and determines whether the injection molding machine 16 can mold the target molded article using this mold.

[0016] In a case where the specification of the injection molding machine 16 can achieve the molding result detected by the resin flow analysis device 14, the molding determination device 90 determines that the injection molding machine 16 can mold the target molded part. In a case where the specification of the injection molding machine 16 cannot achieve the molding result detected by the resin flow analysis device 14, the molding determination device 90 determines that the injection molding machine 16 cannot mold the target molded part.

[0017] Hereinafter, before describing the detailed configuration of the molding detection device 90, the detailed configuration of the resin flow analysis device 14, the injection molding machine 16, and the molding detection device 90 will be described in this order, respectively.

[0021] The analysis unit 24 simulates the flow of the resin in the flow path using a model created for each mold. The analysis unit 24 obtains analysis results such as the position of the tip (melt front) of the resin in the flow path at the time of resin filling, the pressure distribution of the resin in the flow path, and the temperature distribution of the resin in the flow path.

[0022] The molding condition calculation unit 26 calculates a molding condition corresponding to each mold based on the analysis result. Hereinafter, the molding condition calculated by the molding condition calculation unit 26 may be referred to as an analytical molding condition. The analytical molding condition corresponds to molding information of the present invention.

[0025] The analytical molding condition and the analytical molding result are stored as analysis data in an analysis file 30 created in association with each mold. The respective analysis files 30 are stored in the storage unit 22. Injection molding machine configuration

[0026] Fig. 3 is a block diagram illustrating the configuration of the injection molding machine 16.

[0027] The injection molding machine 16 includes a calculation unit 32 and a storage unit 34. The calculation unit 32 is, for example, a processor such as a CPU or a GPU. The calculation unit 32 includes a molding condition setting unit 36 ​​and a molding result generation unit 38.

At least a part of the molding condition setting unit 36 ​​and the molding result generation unit 38 may be implemented by an electronic circuit including a discrete device.

[0028] The storage unit 34 is formed by 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 RAM or the like. The non-volatile memory is, for example, a ROM, a flash memory, or the like. Data and the like are stored, for example, in the volatile memory.

At least a part of the storage unit 34 may be included in the processor, the integrated circuit, or the like described above. At least a part of the storage unit 34 may be mounted on a device connected to the injection molding machine 16 via a network.

[0029] At the time of actual molding, the molding condition setting unit 36 ​​in the injection molding machine 16 sets the molding condition according to a mold mounted on the injection molding machine 16. The molding condition set at this time may not be the analytical molding condition acquired by the resin flow analyzer 14. For example, the molding condition input by an operator may be set. Hereinafter, the molding condition set by the molding condition setting unit 36 ​​in the injection molding machine 16 may be referred to as the actual molding condition. The actual molding condition corresponds to the molding information of the present invention. The actual molding condition includes, for example, a set injection speed, a set clamping force, and the like.

[0030] At the time of actual molding, the molding result generation unit 38 acquires detection values ​​from various sensors mounted on the injection molding machine 16 and the mold, and generates a molding result based on the detection values. The molding result is generated in association with each mold mounted on the injection molding machine 16. Hereinafter, the molding result generated by the molding result generation unit 38 may be referred to as an actual molding result. The actual molding result corresponds to the molding information of the present invention.

[0031] The actual molding condition and the actual molding result are stored as molding data in a molding file 42 created in association with each mold. The respective molding files 42 are stored in the storage unit 34.

[0032] The storage unit 34 stores a specification information file 44 in addition to the molding files 42.

Hereinafter, the information stored in the specification information file 44 may be referred to as specification information. Configuration of the forming detection device

[0033] As in Fig. As shown in Figure 1, the shape determination device 90 includes a calculation unit 48 and a storage unit 50. The calculation unit 48 is, for example, a processor such as a CPU or a GPU. The calculation unit 48 includes a shape information acquisition unit 52, a specification information acquisition unit 54, an input value acquisition unit 92, a shape determination unit 58, and a display control unit 60. The shape information acquisition unit 52, the specification information acquisition unit 54, the input value acquisition unit 92, the shape determination unit 58, and the display control unit 60 are implemented by the calculation unit 48 executing a program stored in the storage unit 50.

[0034] At least a portion of the shape information acquisition unit 52, the specification information acquisition unit 54, the input value acquisition unit 92, the shape determination unit 58, and the display control unit 60 may be implemented by an integrated circuit such as an ASIC or an FPGA. At least a portion of the shape information acquisition unit 52, the specification information acquisition unit 54, the input value acquisition unit 92, the shape determination unit 58, and the display control unit 60 may be implemented by an electronic circuit including a discrete device.

[0035] The storage unit 50 is constituted by 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 RAM or the like. The non-volatile memory is, for example, a ROM, a flash memory, or the like. Data and the like are stored, for example, in the volatile memory. Programs, tables, maps, and the like are stored, for example, in the non-volatile memory. At least a part of the storage unit 50 may be included in the processor, the integrated circuit, or the like described above. At least a part of the storage unit 50 may be mounted on a device connected to the shape detection device 90 via a network.

[0036] The shape information acquisition unit 52 acquires an analytical molding result corresponding to the shape of the target molded part from the resin flow analyzer 14. The specification information acquisition unit 54 acquires specification information from the injection molding machine 16.

[0037] The input value acquisition unit 92 acquires an input value by the operator operating an input unit 66. Fig. 4 is a graphical representation illustrating an input screen 94 displayed on a display unit 18. The display control unit 60 causes the display unit 18 to display the input screen 94. A value input area 96 is displayed on the input screen 94. The operator can input a value into the value input area 96 by operating the input unit 66. The input value acquisition unit 92 acquires the value entered into the value input area 96.

[0038] The shape determination unit 58 determines whether the injection molding machine 16 can mold the target molded part based on the specification information and the analytical molding result, while taking into account an error in the analytical molding result. Specifically, the shape determination unit 58 calculates compensated shape information, which is a value obtained by taking into account an error in the analytical molding result. Furthermore, the shape determination unit 58 determines whether the injection molding machine 16 can mold the target molded part by comparing the compensated shape information with the specification information of the injection molding machine 16.

[0039] The comparison between the compensated mold information and the specification information is performed for each element. These elements include injection pressure, injection rate, injection volume, clamping force, and the like.

[0040] As an example, a method for calculating the compensated shape information with respect to the injection pressure element is described. Fig. Figure 5 is a graphical representation for explaining the method for calculating the compensated shape information with respect to the injection pressure. The shape determination unit 58 obtains the maximum value of the injection pressure. The maximum value of the injection pressure is detected from the change in the injection pressure over time. As shown in Fig. As shown in Figure 4, in a case where the value input into the value input area 96 is "10," the molding determination unit 58 sets a value obtained by multiplying the maximum value of the injection pressure by 1.1 as compensated molding information related to the injection pressure. As a result, the compensated molding information is obtained as an analytical molding result that has been compensated by taking into account the error corresponding to the value input by the operator.

[0041] In a case where the maximum injection pressure of the injection molding machine 16 is equal to or less than the compensated molding information, the molding determination unit 58 determines that the injection molding machine 16 cannot mold the target molded part. As shown in Fig. As shown in Figure 5, in a case where the maximum injection pressure of the injection molding machine 16 is greater than the compensated shape information, the molding determination unit 58 compares the compensated shape information obtained from the analytical molding result with the specification information for other elements. In a case where the specification information can obtain the compensated shape information for all elements, the molding determination unit 58 determines that the injection molding machine 16 can mold the target molded part.

[0042] The compensated shape information relating to the respective elements is obtained as follows. The shape determination unit 58 obtains, as compensated shape information relating to the injection rate, the maximum value of the injection rate that has been compensated according to the value inputted into the value inputting area 96. The maximum value of the injection rate is detected from the change in the injection rate over time. The shape determination unit 58 obtains, as compensated shape information relating to the injection volume, the maximum value of the injection volume that has been compensated according to the value inputted into the value inputting area 96. The maximum value of the injection volume is detected from the change in the injection rate over time.The forming determination unit 58 obtains, as compensated forming information with respect to the closing force, the maximum value of the closing force, which has been compensated according to the value entered in the value input area 96. The maximum value of the closing force is detected from the change in the required closing force over time. Forming determination process

[0043] Fig. 6 is a flowchart illustrating a shape determination process performed by the shape determination device 90. For example, the shape determination process is performed in a case where the operator instructs the execution of the shape determination process using the input unit 66.

[0044] In step S1, the specification information acquisition unit 54 acquires the specification information from the injection molding machine 16. Then, the process proceeds to step S2.

[0045] In step S2, the molding information acquisition unit 52 acquires the analytical molding result from the resin flow analyzer 14. Then, the process proceeds to step S3.

[0046] In step S3, the molding determination unit 58 determines whether the injection molding machine 16 can mold the target molded part based on the specification information and the analytical molding result, while taking into account the error of the analytical molding result. The molding determination process is then terminated. Operating effect

[0047] In the molding determination device 90 of the present embodiment, the molding determination unit 58 determines whether the injection molding machine 16 can mold the target molded part based on the specification information and the analytical molding result, while taking into account the error of the analytical molding result. As a result, the molding determination device 90 can improve the accuracy of the determination regarding whether the injection molding machine 16 can mold the target molded part.

[0048] Furthermore, in the shape determination device 90 of the present embodiment, the shape determination unit 58 calculates the compensated shape information, which is the analytical shape result compensated for by taking into account the error of the analytical shape result. Furthermore, the shape determination unit 58 determines whether the injection molding machine 16 can mold the target molded part by comparing the compensated shape information with the specification information. As a result, the shape determination device 90 can improve the accuracy of the determination regarding whether the injection molding machine 16 can mold the target molded part.

[0049] Furthermore, in the shape determination device 90 of the present embodiment, an error corresponding to the value input by the operator operating the operation unit 66 is taken into account. As a result, the shape determination device 90 can adjust the determination accuracy according to the value input by the operator. Second embodiment

[0050] The molding determination device 90 of the first embodiment determines whether the injection molding machine 16 can mold the target molded part by comparing the compensated molding information obtained from the analytical molding result with the specification information of the injection molding machine 16. In contrast, the molding determination device 90 of the present embodiment determines whether the injection molding machine 16 can mold the target molded part by comparing the compensated specification information obtained from the specification information of the injection molding machine 16 with the analytical molding result. The other configuration of the molding determination device 90 is the same as that of the molding determination device 90 of the first embodiment.

[0051] As an example, a method for calculating the compensated specification information related to the injection pressure is described. Fig. Figure 7 is a graphical representation for explaining the method for calculating the compensated specification information related to the injection pressure. As shown in Fig. As shown in Figure 4, in a case where the value input into the value input area 96 is "10," the molding determination unit 58 sets a value obtained by multiplying the maximum injection pressure, which is the specification information of the injection molding machine 16, by 0.9 as compensated specification information related to the injection pressure. As a result, the compensated specification information is obtained as specification information that has been compensated by taking into account the error corresponding to the value input by the operator.

[0052] In a case where the compensated specification information is equal to or less than the maximum value of the injection pressure, the molding determination unit 58 determines that the injection molding machine 16 cannot mold the target molded part. As shown in Fig. As shown in Figure 7, in a case where the compensated specification information is greater than the maximum injection pressure, the molding determination unit 58 compares the compensated specification information obtained from the specification information with the analytical molding result for other elements. In a case where the compensated specification information can achieve the analytical molding result for all elements, the molding determination unit 58 determines that the injection molding machine 16 can mold the target molded part. Operating effect

[0053] In the molding determination device 90 of the present embodiment, the molding determination unit 58 calculates the compensated specification information corresponding to the specification information taking into account the error of the analytical molding result. Furthermore, the molding determination unit 58 determines whether the injection molding machine 16 can mold the target molded part by comparing the analytical molding result with the compensated specification information. As a result, the molding determination device 90 can improve the accuracy of the determination regarding whether the injection molding machine 16 can mold the target molded part. Third embodiment

[0054] In the shape detecting device 90 of the first embodiment, the input value detecting unit 92 detects a value input into the value input area 96 by the operator operating the input unit 66 ( Fig. 4). In contrast, in the shape determination device 90 of the present embodiment, the input value acquisition unit 92 acquires a value corresponding to an option 100 selected by the operator operating the input unit 66.

[0055] Fig. 8 is a graphical representation illustrating the input screen 94 displayed on the display unit 18. The display control unit 60 causes the display unit 18 to display the input screen 94. Options 100A through 100E are displayed on the input screen 94. The operator can select one of the options 100A through 100E by operating the input unit 66.

[0056] Each of the options 100A to 100D is assigned a value. For example, a value of "30 (%)" is assigned to option 100A. A value of "20 (%)" is assigned to option 100B. A value of "10 (%)" is assigned to option 100C. A value of "15 (%)" is assigned to option 100D. The input value acquisition unit 92 acquires a value associated with the selected option 100.

[0057] In a case where option 100E is selected, the Fig. 4 may be displayed on the display unit 18. In this case, the input value acquisition unit 92 acquires the value entered into the value input area 96.

[0058] The molding determination unit 58 calculates the compensated molding information according to the value corresponding to the option 100 selected by the operator. Furthermore, the molding determination unit 58 determines whether the injection molding machine 16 can mold the target molded part by comparing the compensated molding information with the specification information of the injection molding machine 16. Operating effect

[0059] In the shape determination device 90 of the present embodiment, the display control unit 60 causes the display unit 18 to display the plurality of options 100. Furthermore, the shape determination unit 58 considers an error corresponding to the option 100 selected by the operator operating the input unit 66. As a result, the accuracy of the determination by the shape determination device 90 can be adjusted according to the option 100 selected by the operator. Fourth embodiment

[0060] In the shape detecting device 90 of the first embodiment, the input value detecting unit 92 detects a value input into the value input area 96 by the operator operating the input unit 66 ( Fig. 4). In contrast, in the shape detection device 90 of the present embodiment, the input value detection unit 92 detects a value corresponding to the position of a slider 104 moved on a slide bar 102 by the operator operating the input unit 66.

[0061] Fig. 9 is a graphical representation illustrating the input screen 94 displayed on the display unit 18. The display control unit 60 causes the display unit 18 to display the input screen 94. The slide bar 102 and the slider 104 are displayed on the input screen 94. The operator can move the slider 104 along the slide bar 102 by operating the input unit 66. A value corresponding to the position of the slider 104 on the slide bar 102 is assigned.

[0062] The molding determination unit 58 calculates the compensated molding information according to the value corresponding to the position of the slider 104. Furthermore, the molding determination unit 58 determines whether the injection molding machine 16 can mold the target molded part by comparing the compensated molding information with the specification information of the injection molding machine 16. Operating effect

[0063] In the shape detection device 90 of the present embodiment, the display control unit 60 causes the display unit 18 to display the slide bar 102 and the slider 104. Furthermore, the shape detection unit 58 considers an error corresponding to the position of the slider 104 moved by the operator operating the input unit 66. As a result, the accuracy of the detection by the shape detection device 90 can be adjusted according to the position of the slider 104 moved by the operator. Fifth embodiment

[0064] In the shape determination device 90 of the present embodiment, the shape determination unit 58 compares the compensated shape information with the specification information of the injection molding machine 16 for each item selected by the operator.

[0065] Fig. 10 is a graphical representation illustrating the input screen 94 displayed on the display unit 18. The display control unit 60 causes the display unit 18 to display the input screen 94. Item selection buttons 106, the slider bar 102, and the slider 104 are displayed on the input screen 94.

[0066] Item selection buttons 106A to 106D are provided corresponding to the items injection pressure, injection rate, injection volume, and clamping force, respectively. The operator can switch the display of each item selection button 106 between "ON" and "OFF" by operating the item selection button 106 using the input unit 66. For the item whose display is set to "ON," the slide bar 102 and the slider 104 can be displayed on the display unit 18, as shown in Fig. 10 shown.

[0067] The molding determination unit 58 calculates the compensated shape information with respect to each element for which the display of the element selection button 106 is "ON." The molding determination unit 58 compares the compensated shape information with the specification information for each element for which the display of the element selection button 106 is "ON." In a case where the specification information can obtain the compensated shape information for all elements, the molding determination unit 58 determines that the injection molding machine 16 can mold the target molded part. Operating effect

[0068] In the shape determination device 90 of the present embodiment, the display control unit 60 causes the display unit 18 to display the item selection buttons 106 for selecting the respective items used for determination. Furthermore, the shape determination unit 58 compares the compensated shape information with the specification information of the injection molding machine 16 for the item selected by the operator operating the input unit 66 and determines whether the injection molding machine 16 can mold the target molded part. As a result, it is possible to determine whether the injection molding machine 16 can mold the target molded part based on the item selected by the operator. Sixth embodiment

[0069] The shape determination device 90 of the first embodiment adjusts the compensated shape information with respect to each element based on the analytical molding result acquired by the resin flow analysis device 14, in accordance with the shape of the target molded part. In contrast, the shape determination device 90 may adjust the compensated shape information with respect to each element based on the analytical molding condition acquired by the resin flow analysis device 14, in accordance with the shape of the target molded part.

[0070] In this case, the shape information acquisition unit 52 acquires an analytical molding condition corresponding to the shape of the target molded article from the resin flow analysis device 14. The other configuration of the shape determination device 90 is the same as that in the first embodiment.

[0071] The molding determination unit 58 obtains the compensated molding information with respect to each element from the analytical molding condition. For example, the molding determination unit 58 obtains, as the compensated molding information with respect to the injection rate, the set injection rate that has been compensated according to the value inputted into the value input area 96 ( Fig. 4). The set injection rate is the analytical molding condition.

[0072] It should be noted that the compensated shape information with respect to each element may include both the compensated shape information obtained from the analytical shaping result and the compensated shape information obtained from the analytical shaping condition.

[0073] The molding determination unit 58 determines whether the specification information of the injection molding machine 16 satisfies the compensated shape information with respect to each element of the injection molding machine 16. If the specification information of the injection molding machine 16 satisfies the compensated shape information with respect to all elements, the molding determination unit 58 determines that the injection molding machine 16 can mold the target molded part. Conversely, if the specification information of the injection molding machine 16 does not satisfy the compensated shape information with respect to one or more elements, the molding determination unit 58 determines that the injection molding machine 16 cannot mold the target molded part. Operating effect

[0074] In the molding determination device 90 of the present embodiment, the molding determination unit 58 calculates the compensated molding information, which is the analytical molding condition compensated for by taking into account the error of the analytical molding result. Furthermore, the molding determination unit 58 determines whether the injection molding machine 16 can mold the target molded part by comparing the compensated molding information with the specification information. As a result, the molding determination device 90 can improve the accuracy of the determination regarding whether the injection molding machine 16 can mold the target molded part. Seventh embodiment

[0075] The shape determination device 90 of the first embodiment adjusts the compensated shape information with respect to each element based on the analytical molding result acquired by the resin flow analysis device 14, in accordance with the shape of the target molded part. In contrast, the shape determination device 90 may adjust the compensated shape information with respect to each element based on the actual molding result acquired by the injection molding machine 16, in accordance with the shape of the target molded part.

[0076] In this case, the shape information acquisition unit 52 of the injection molding machine 16 acquires the actual molding result according to the shape of the target molded part. The other configuration of the shape detection device 90 is the same as that in the first embodiment.

[0077] The compensated shape information with respect to the respective elements is obtained as follows. The shape determination unit 58 obtains, as compensated shape information with respect to the injection pressure, the maximum value of the injection pressure that has been compensated according to the value inputted into the value input area 96 ( Fig. 4). The maximum injection pressure value is acquired from the change in the injection pressure of the actual molding result over time. The molding determination unit 58 obtains, as compensated molding information related to the injection rate, the maximum injection rate value that has been compensated according to the value inputted into the value inputting area 96. The maximum injection rate value is acquired from the change in the injection speed of the actual molding result over time and the screw diameter of the injection molding machine 16. The molding determination unit 58 obtains, as compensated molding information related to the injection volume, the maximum injection volume value that has been compensated according to the value inputted into the value inputting area 96.The maximum value of the injection volume is obtained from the injection stroke of the actual molding result and the screw diameter of the injection molding machine 16.

[0078] It should be noted that the compensated shape information with respect to each element may include the compensated shape information obtained from the analytical forming result, the compensated shape information obtained from the analytical forming condition, and the compensated shape information obtained from the actual forming result. Operating effect

[0079] Even in a case where the same molded part is molded, the actual molding results detected by different injection molding machines 16 may differ from each other. Furthermore, even in a case where the same injection molding machine 16 molds the same molded part, the actual molding result to be detected may vary depending on the environment such as temperature and humidity.

[0080] In the molding determination device 90 of the present embodiment, the molding determination unit 58 calculates the compensated molding information, which is the actual molding condition compensated for by taking into account the error of the actual molding result. Furthermore, the molding determination unit 58 determines whether the injection molding machine 16 can mold the target molded part by comparing the compensated molding information with the specification information. As a result, the molding determination device 90 can improve the accuracy of the determination regarding whether the injection molding machine 16 can mold the target molded part. Eighth embodiment

[0081] The shape determination device 90 of the first embodiment adjusts the compensated shape information with respect to each element based on the analytical molding result acquired by the resin flow analysis device 14, in accordance with the shape of the target molded part. In contrast, the shape determination device 90 may adjust the compensated shape information with respect to each element based on the actual molding condition acquired by the injection molding machine 16, in accordance with the shape of the target molded part.

[0082] In this case, the shape information acquisition unit 52 of the injection molding machine 16 acquires the actual molding condition corresponding to the shape of the target molded part. The other configuration of the shape detection device 90 is the same as that in the first embodiment.

[0083] The compensated shape information with respect to the respective elements is obtained as follows. The shape determination unit 58 obtains, as compensated shape information with respect to the injection rate, the maximum value of the injection rate that has been compensated according to the value inputted into the value input area 96 ( Fig. 4). The maximum injection rate is obtained from the set injection speed of the actual molding condition and the screw diameter of the injection molding machine 16. The molding determination unit 58 obtains, as compensated molding information related to the clamping force, the maximum clamping force value that has been compensated according to the value input in the value input area 96. The maximum clamping force value is obtained from the set clamping force of the actual molding condition.

[0084] It should be noted that the compensated shape information with respect to each element may include the compensated shape information obtained from the analytical shaping result, the compensated shape information obtained from the analytical shaping condition, the compensated shape information obtained from the actual shaping result, and the compensated shape information obtained from the actual shaping condition. Operating effect

[0085] In the molding determination device 90 of the present embodiment, the molding determination unit 58 calculates the compensated molding information, which is the actual molding condition compensated for by taking into account the error of the actual molding result. Furthermore, the molding determination unit 58 determines whether the injection molding machine 16 can mold the target molded part by comparing the compensated molding information with the specification information. As a result, the molding determination device 90 can improve the accuracy of the determination regarding whether the injection molding machine 16 can mold the target molded part.
