Description

  The present invention relates to a design support apparatus, a design support method, a design support program, and a recording medium on which a design support program is recorded that is preferably used when designing a mold, for example.

In designing products, a two-dimensional CAD (Computer Aided Design) apparatus has been used, but in recent years, a three-dimensional CAD apparatus has been widely used to accurately express a designer's intention. For example, in the mold design department, using 3D product shape data, design using 3D data is performed, such as generating parting data representing the shape of the product molded by the mold, A three-dimensional CAD apparatus is used not only for the split shape but also for designing a mold base. When designing a mold using a 3D CAD device, if the product shape is changed, modify the parting data or regenerate the parting data, replace the parting data, Design data such as ejector pin holes and cooling holes that have been designed so far are input again and the design work is performed.

  In the mold design apparatus described in Patent Document 1, when the shape of a product is changed, a fixed part shape and a movable part shape of the mold are created based on the shape of the product, and the fixed part shape of the mold and When creating the movable part shape, associate the positional relationship between the fixed part shape of the mold and the movable part shape with the product shape in advance, and when the product shape is changed, Based on the data representing the positional relationship between the product shape and the fixed part shape and movable part shape of the mold, the shape data of the product before the change is subtracted from the shape data of the product that has been changed. The product shape change is reflected by calculating the deformation amount of the product shape and adding or deleting the data representing the calculated deformation amount to the data representing the fixed part shape and movable part shape of the created mold. Mold fixing part And to generate data representative of Jo and movable portion shape.

JP 2001-76015 A

  As mentioned above, when designing the mold, if the product shape is changed, not only the generated parting data is modified, but also the mold base design data is modified according to the modification of the parting data. There is a problem that must be done. To change the parting data, if there are only a few parts of the product shape changed, it is possible to correct only the parting data corresponding to the changed part, but it corresponds to the changed part. In order to correct only the parting data, a very skilled operation technique of the three-dimensional CAD device is required, and the parting data may not be corrected depending on the change in the product shape. In this way, when the parting data cannot be corrected even if there are only a few parts of the product shape changed, and if there is a significant change in the product shape, the parting data is stored based on the product shape after the change. However, in these cases, the part shape data representing the shape of the ejector pin holes and cooling holes designed in the mold base data until the product shape is changed will be discarded. Since it is necessary to regenerate the part shape data every time the product shape is changed, there is a problem that the number of processes increases, and it takes a long time to generate completion data of a mold that is a design object.

  Further, in the mold design apparatus described in Patent Document 1, the deformation data of the product shape before and after the change is calculated by subtracting the shape data of the product before the change from the shape data of the changed product. When the data indicating the deformation amount is added to the data indicating the fixed part shape and the movable part shape of the mold, the mold part in which the ejector pin holes designed by the time the product shape is changed is formed. Cannot be made, and there is a problem that it must be corrected again so as to form an ejector pin hole in the mold part.

  An object of the present invention is to provide a design support apparatus, a design support method, a design support program, and a design capable of easily and relatively quickly generating completion data of a design object reflecting item data in which design items have been changed. It is to provide a recording medium on which a support program is recorded.

The present invention includes a data input means for inputting item data for each of a plurality of design items of a design object;
Storage means for storing item data input by the data input means;
Computation means that generates completion data of the design object by synthesizing each item data, and some of the item data of some design items among the design items are newly input by the data input means. A calculation means for reading out the item data of the remaining design items other than the design items from the storage means, and synthesizing the item data with the newly input item data to newly generate completed data. This is a design support device.

  According to the present invention, item data for each of a plurality of design items of the design object is input to the data input means. The storage means stores item data input by the data input means. When item data of some design items among the design items is newly input, the item data of the remaining design items other than some design items is read from the storage unit by the calculation unit, and the reading is performed. The input item data and the newly input item data are synthesized, and the completion data of the design object is newly generated. As described above, when item data of some design items among the design items is newly input, the item data is stored in the storage unit until the item data is newly input as in the conventional technique. In addition, it is not necessary to discard and re-generate the item data of the remaining design items other than the part of the design items. As a result, the process of discarding the item data of the remaining design items other than the part of the design items and generating them again becomes unnecessary. Therefore, even when item data of some design items among the design items is newly input, the item data of the remaining design items other than the some design items stored in the storage unit can be diverted. In addition, by combining the item data of the remaining design items and the newly input item data, new completion data of the design object can be easily generated in a relatively short time.

As another design item, it has an essential data input unit for inputting essential data representing a shape inevitably required for the mold.

  According to the invention, the parting data input part of the data input means is inputted with parting data representing the shape of the product molded by the mold as one design item in the parting data input part of the data input means. In addition, as another design item, essential data representing the shape inevitably required for the mold is input. The storage means stores parting data input to the parting data input unit and essential data input to the essential data input unit. When item data of some design items among design items, for example, parting data, is newly input, the arithmetic means reads item data of remaining design items other than parting data, for example, essential data from the storage means. The essential data that has been read out and the newly entered parting data are synthesized, and the completion data of the design object is newly generated. As described above, when the parting data is newly input, the required data stored in the storage means is discarded until the parting data is newly input as in the conventional technique, and is generated again. There is no need to redo. As a result, the process of discarding the essential data and generating it again becomes unnecessary. Therefore, even when the parting data is newly input, the essential data stored in the storage means can be diverted, and it is easy to synthesize the essential data and the newly inputted parting data. In addition, it is possible to newly generate completion data of a mold that is a design object in a relatively short time.

  Further, according to the present invention, the completion data is generated by combining each item data, for example, parting data and essential data, by a logical operation by the arithmetic means. Thus, since each item data is synthesized by logical operation, the product shape data before and after the change is subtracted from the shape data of the product before the change from the shape data of the changed product as in the conventional technique. Completion data can be generated more easily than in the case of performing a calculation process in which the deformation amount is calculated and data representing the calculated deformation amount is added to or deleted from the parting data.

Further, the present invention is a design support device for designing the mold part having a mold part that represents the shape of a product to be molded and a plate that holds the part part by a holding part as a design object. And

  Further, according to the present invention, the shape represented by the holding unit data, specifically, the shape of the holding unit of the plate that holds the mold shape that represents the shape of the product to be molded is calculated by the calculating means. The holding portion data is thinned so as to be deformed into a thin shape that remains only in contact with the thin portion, and thin data is generated, and the thin portion data and the parting data are synthesized by a logical operation. As described above, thinning processing is performed on the holding unit data to generate thin data, and the thin data and the parting data thus generated are combined by a logical operation, for example, a logical sum operation to represent the parting data. Regardless of the shape, it is possible to reliably create a parting reflecting the shape represented by the parting data.

In the present invention, the essential data further includes operation space data representing a shape of an operation space for processing and operating at least one of a material and a product when molding using a mold,
The computing means is characterized in that the thin data and the parting data are synthesized by a logical operation, and the logically operated data and the operation space data are synthesized.

The thin data and the parting data are synthesized by a logical operation by the arithmetic means, and the data synthesized by the logical operation and the operation space data representing the shape of the operation space are synthesized. As described above, after thin data and parting data are combined by logical operation, the operation space represented by the operation space data is reflected by combining the data combined by the logical operation and operation space data. It is possible to surely create the mold that has been made.

Further, in the present invention, the operation space data has data representing a positional relationship between the plate holding portion and the operation space,
The storage means stores operation space data and holding unit data in association with each other.

  According to the invention, the storage means stores operation space data having data representing the positional relationship between the plate holding portion and the operation space, and the holding portion data in association with each other. Therefore, based on the data representing the positional relationship between the holding portion of the plate and the operation space included in the operation space data, the thin data and the parting data generated by thinning the holding portion data are logically calculated. The synthesized data and the operation space data can be synthesized easily and reliably.

  Further, according to the present invention, the calculation means stores the generated completion data in the storage means, and when item data of some design items among the design items is newly input by the data input means, the item data is When there is completed data generated by the item data input before newly input, the items of the partial design items input before the item data is newly input from the completed data It is characterized by discarding data.

  Further, according to the present invention, the generated completion data is stored in the storage unit by the calculation unit. When item data of some design items among the design items is newly input by the data input means, there is completed data generated by the item data input before the item data is newly input. Sometimes, from the completion data, the item data of the part of design items input before the item data is newly input is discarded by the calculation means. Accordingly, when item data of some design items among the design items is newly input by the data input means, the newly input item data and the item data discarded from the completed data by the arithmetic means By combining the item data of the remaining design items other than the above, it is possible to reliably generate the completion data of the design object reflecting the shape represented by the newly input item data.

  In FIG. 5, the operation processing of the design support apparatus 1 is started in step a0 when the mold 40 is designed as a design object, and proceeds to step a1. In step a1, when designing the mold 40, the mold base data designer obtains mold base shape data, specifically, plate data and mold shape synthesis data input to the mold base data input means 11. . At this time, the mold base data designer determines the dimensions of the mold base and the mold part 51 in advance based on the external dimensions of the product 50 to be molded, and the mold base based on the predetermined dimensions. Create shape data. However, if it is necessary to change the dimensions due to subsequent product shape changes or molding machine conditions, corrections are made at that time. If mold base shape data is acquired, it will progress to step a2.

  In step a2, based on the die shape data representing the shapes of the ejector pin hole 47 and the cooling hole 48 input to the die shape data input means 12, the plate data and the parting shape combining data acquired in step a1 are processed.

Can be improved. When the parting data is stored in the parting data storage means 22, the process proceeds to step a5.

  When the parting data is created, the mold base data designer moves to the work of synthesizing the parting shape synthesis data and the parting data. In step a5, the data composition calculation processing unit 30 reads out the parting shape composition data stored in the mold base data storage unit 13 based on a command from the mold base data designer. When the parting shape synthesis data is read, the process proceeds to step a6.

  In step a6, it is determined whether or not old composite data, specifically, parting data has been combined with the parting shape combining data read from the mold base data storage means 13, and if it has been combined, step a7 is performed. If not, the process proceeds to step a8. When the parting data is created for the first time, the parting data is not composited with the parting composition data read from the mold base data storage means 13, so the process proceeds to step a8. In addition, when the shape of the product 50 is updated due to a design change or the like, and the parting data is created accordingly, the parting data for the parting shape synthesis and the parting data are combined before, so the step Proceed to a7.

  In step a7, the old composite data deleting means 31 uses the data obtained by combining the old part split data and the part split shape combining data input before the part split data input means 21 newly inputs the part split data. , Delete old mold split data. When the old mold split data is deleted, the process proceeds to step a8.

  In step a8, the thinning processing means 32 applies the shape represented by the remaining parting shape combining data of the data from which the old parting data has been deleted by the old composite data deleting part 31 to the holding part 44 of the plate 41. The mold split shape composition data is deformed so that only the part that comes into contact, more specifically, the part that comes into contact with the cavity side holding part 45 of the cavity plate 42 and the part that comes into contact with the core side holding part 46 of the core plate 43 remains. Is thinned to generate thin data.

  In step a11 to be described later, when combining two different data, specifically, the parting shape synthesis data and parting data by performing an OR operation, as shown in FIG. 6, the shape represented by the parting data When the concave portion is included in the shape represented by the combined data generated by combining the parting shape synthesis data and the parting data by the logical sum operation, There is a problem that the shape cannot be reflected, in other words, the shape represented by the combined data cannot be a shape including the concave portion.

  Therefore, in this embodiment, in order to solve the problem that the shape represented by the composite data cannot reflect the shape of the recess included in the shape represented by the parting data, as shown in FIG. Thin data is generated by performing thinning processing on the split shape synthesis data, and the generated thin data and mold split data are combined by logical sum operation to generate composite data. As a result, when thin data and parting data representing the parting shape having the shape of the recess are combined by logical sum operation, the combined data generated by combining is included in the shape represented by parting data. The shape of the recessed portion to be reflected can be reliably reflected.

  Specifically, in the thinning process in step a8, the mold base data designer inputs a processing command prepared in advance to execute a thinning process such as a cut command or a thinning command, and the thinning process is performed. This is done by giving a command for executing the process to the data composition calculation processing unit 30. When the thinning process is performed, in order not to depend on the shape of the mold split, for example, the thickness dimension is set to 0.1 mm so that only the portion contacting the holding portion 44 of the plate 41 is deformed to remain thin. What is necessary is just to perform a thinning process. In step a8, after thinning processing is performed on the parting composition data, the process proceeds to step a9.

  In step a9, the data composition calculation processing unit 30 reads out the parting data stored in the parting data storage means 22 based on a command from the mold base data designer. When the parting data is read, the process proceeds to step a10. In step a10, the alignment means 33 is based on the thin data generated by the thinning processing means 32 and the parting data read out by the data synthesis arithmetic processing part 30. Perform the alignment process. At this time, if a coordinate system for the reference position of the mold base is created for the holding unit 44 related to the thin data and the mold part 51 related to the mold data, the coordinate system is assembled to match the coordinate system. By performing the above, alignment can be performed easily. When the alignment process is performed in step a10, the process proceeds to step a11.

  In step a11, the data synthesizing unit 34 synthesizes the thin data generated by the thinning processing unit 32 and the parting data read from the parting data storage unit 22 by, for example, a logical sum operation. The thin data and the parting data are synthesized by the logical sum operation as follows.

  In the data composition unit 34, a predetermined coordinate point of the coordinate system created when the alignment by the alignment unit 33 is performed may be expressed as a virtual solid represented by the thin data (hereinafter simply referred to as “thin virtual solid”). ) And whether or not the predetermined coordinate point exists inside the mold part 51. When the data composing unit 34 determines that the coordinate point does not exist in either the thin virtual solid or the mold part 51, composite data generated by compositing the thin data and the part data is generated. It is assumed that the coordinate point does not exist within a solid represented by (hereinafter, simply referred to as “synthetic solid” in some cases). Further, when it is determined by the data synthesizing unit 34 that the coordinate point is present in at least one of the thin virtual solid and the mold part 51, the coordinate point is present in the synthetic solid. . In this way, a composite solid is created by connecting coordinate points determined to be present inside the composite solid.

  More specifically, when performing the logical sum operation, the first input value is represented by the numerical value “1” when the predetermined coordinate point is present inside the thin virtual solid, and is represented by the numerical value “0”. To express. Further, as the second input value, a case where the coordinate point exists inside the mold part 51 is represented by a numerical value “1”, and a case where the coordinate point does not exist is represented by a numerical value “0”. In the logical sum operation, when both the first input value and the second input value are the numerical value “0”, the numerical value “0” is output as the output value, and the first input value and the second input value are When at least one of them is the numerical value “1”, the numerical value “1” is output as the output value. Here, when the output value is a numerical value “0”, it indicates that the predetermined coordinate point does not exist inside the composite solid, and when the output value is a numerical value “1”, the predetermined coordinate point is Represents the presence of a synthetic solid. When the thin data and the parting data are combined in step a11, the process proceeds to step a12.

  In step a12, the completion data generating unit 35 combines the data generated by combining the thin data and the parting data with the data combining unit 34 and the mold shape data by a logical product operation, so that the design object Generate completed data. Here, the mold shape data represents the shapes of the ejector pin holes 47 and the cooling holes 48 inputted by the mold shape data input means 12, and the dimensions of the shapes of the ejector pin holes 47 and the cooling holes 48 are the combined molds. It includes the dimensions of the parting shape represented by the parting data.

  Originally, the mold shape data representing the shapes of the ejector pin holes 47 and the cooling holes 48 input by the mold shape data input means 12, and the parting shape combining data input by the mold base shape data input means 11 After completing the process of combining the thinned data generated by performing the thinning process on the combined data and the parting data, the completed data should be generated by a logical sum operation. However, when such a synthesis process is performed, as shown in FIG. 8, the ejector pin hole included in the shape of the thin data is added to the shape represented by the synthesized data generated by synthesizing the thin data and the parting data. The problem that the shape of 47 and the cooling hole 48 cannot be reflected arises.

  Therefore, in this embodiment, in order to solve the problem that the shape of the ejector pin hole 47 and the cooling hole 48 included in the shape of the thin data cannot be reflected in the shape represented by the composite data, as shown in FIG. As described above, after performing the mold base data input processing, the logical sum operation processing is performed, and thereafter, the data generated by the logical sum operation processing and the mold shape data are combined by the logical product operation. To do. Here, the mold shape data represents the shapes of the ejector pin holes 47 and the cooling holes 48, and the dimensions of the shapes of the ejector pin holes 47 and the cooling holes 48 represent the dimensions of the shape of the mold parts represented by the combined parting data. Including.

  As described above, after performing the mold base data input processing, the logical sum operation processing is performed, and then the data generated by the logical sum operation processing and the mold shape data are combined by the logical product operation. Thus, as shown in FIG. 10, the shape of the ejector pin hole 47 included in the shape of the thin data can be reflected in the shape represented by the composite data generated by combining the thin data and the parting data. . When the completion data of the design object is generated in step a12, the process proceeds to step a13.

  In step a13, the completion data generation means 35 stores the generated completion data in the mold base data storage means 13 on the basis of a command from the mold base data designer, and continues using the completion data to continue plate data and mold assignment. Design work related to the arrangement of the ejector pin holes 47 and the cooling holes 48 for the shape synthesis data is performed, and the process proceeds to step a14. In step a14, all the operation processes of the design support apparatus 1 are finished.

  In step a11 described above, the thin data and the parting data are synthesized by a logical sum operation, but may be synthesized by a logical product operation. Combining by thinning data and mold division data in step a11, and synthesis by logical product operation of data generated by combining thin data and mold division data in step a12 and mold shape data Is performed as follows. Specifically, when it is determined by the data synthesizing means 34 that the predetermined coordinate point does not exist in any of the thin virtual solid and the mold split 51, and the coordinate point is a thin virtual solid and a mold. When it is determined that any one of the percents 51 exists, the coordinate point does not exist inside the composite solid. Further, when it is determined that the coordinate point is present in any of the thin virtual solid and the mold part 51, the coordinate point is present in the composite solid. In this way, a composite solid is created by connecting coordinate points determined to be present inside the composite solid.

  More specifically, when performing the logical product operation, the first input value is represented by the numerical value “1” when the predetermined coordinate point exists inside the thin virtual solid, and the numerical value “0” when the predetermined coordinate point does not exist. To express. Further, as the second input value, a case where the coordinate point exists inside the mold part 51 is represented by a numerical value “1”, and a case where the coordinate point does not exist is represented by a numerical value “0”. In the logical product operation, when at least one of the first input value and the second input value is the numerical value “0”, the numerical value “0” is output as the output value, and the first input value and the second input value are output. When both of the input values are the numerical value “1”, the numerical value “1” is output as the output value. When the output value is “0”, it indicates that the predetermined coordinate point does not exist inside the composite solid, and when the output value is “1”, the predetermined coordinate point is that of the composite solid. Represents inside. As described above, when the thin data and the parting data are combined by the logical product operation in the above-described step a11, the thinning process in step a8 is not necessary.

  As described above, according to the present embodiment, when the parting data is newly stored in the parting data storage means 22 and the parting data is newly input by the parting data input means 21, As in the above technique, it is not necessary to discard the mold base data stored in the mold base data storage means 13 and re-generate it until new parting data is input. This eliminates the need to discard the mold base data and regenerate it. Therefore, even when the parting data is newly input by the parting data input unit 21, the mold base data stored in the mold base data storage unit 13 can be diverted, and the mold base data and the new input can be input. By combining the divided parting data, completed data representing the shape of the mold 40 that is the design object can be newly generated easily and in a relatively short time.

  In addition, according to the present embodiment, the completion data is obtained by performing a logical operation on the data generated by combining the thin data and the parting data by a logical operation by the data combining operation processing unit 30 and the mold shape data. Generate by synthesis. Thus, since each item data is synthesized by logical operation, the product shape data before and after the change is subtracted from the shape data of the product before the change from the shape data of the changed product as in the conventional technique. Completion data can be generated more easily than in the case of performing a calculation process in which the deformation amount is calculated and data representing the calculated deformation amount is added to or deleted from the parting data.

  Further, according to the present embodiment, thinning processing is performed on the parting shape synthesis data to generate thinness data, and the generated thinness data and parting data are synthesized by a logical operation, for example, a logical sum operation. Thus, the mold part 51 reflecting the shape represented by the parting data can be surely created regardless of the form represented by the parting data.

  Further, according to the present embodiment, after the thin data and the parting data are synthesized by the logical operation, the data synthesized by the logical operation and the die shape representing the shapes of the ejector pin hole 47 and the cooling hole 48 are combined. By combining the data, the mold 40 reflecting the shapes of the ejector pin hole 47 and the cooling hole 48 represented by the mold shape data can be reliably created.

  Further, according to the present embodiment, the mold base data storage means 13 includes the mold shape data having data representing the positional relationship between the holding portion 44 of the plate 41, the ejector pin holes 47 and the cooling holes 48, and the mold. Since the split shape combining data is stored in association with each other, based on the data representing the positional relationship between the holding portion 44 of the plate 41, the ejector pin hole 47 and the cooling hole 48 included in the mold shape data, It is possible to easily and reliably synthesize the data obtained by combining the thin wall data generated by thinning the mold split shape synthesis data and the mold split data by a logical operation and the mold shape data.

  Further, according to the present embodiment, the old composite data deletion means 31 obtains the old part split data and the part split shape composition data inputted before the part split data is newly input to the part split data input means 21. Since the old parting data is deleted from the synthesized data, when parting data is newly input by the parting data input means 20, the newly entered parting data and parting shape combining data By combining the two, the completed data of the design object reflecting the shape of the newly inputted parting data can be generated with certainty.

  According to the present embodiment, the mold base shape data input by the mold base shape data input unit 11, the mold shape data input by the mold shape data input unit 12, and the mold data input unit 21 Since the mold division data is mutually independent data, the design work of the mold base shape data, the mold shape data, and the mold division data can be simultaneously performed by a plurality of design workers. The work efficiency for the design work can be improved.

  Next, the design support apparatus which is the 2nd Embodiment of this invention is demonstrated. Since the design support apparatus according to the second embodiment is similar to the design support apparatus 1 according to the first embodiment described above, only the different parts will be described, and the same components are denoted by the same reference numerals. Therefore, the description is omitted. In the mold shape data input means 12 of the present embodiment, in addition to the data representing the shapes of the ejector pin holes 47 and the cooling holes 48 described in the above-described embodiment, as mold shape data corresponding to the operation space data. Thus, data representing the shapes of the gate hole 60 and the runner hole 61 are respectively input. The gate hole 60 is an injection hole for injecting a molten molding material (hereinafter sometimes simply referred to as “molding material”), and is formed in the mold 40. The runner hole 61 is a path through which the molding material injected from the gate hole 60 leads to a cavity representing a space corresponding to a molded product in the mold 40, and is formed in the mold 40.

  The mold shape data input by the mold shape data input unit 12 is stored in the mold base data storage unit 13. The mold base data storage means 13 includes mold shape data having data representing the positional relationship between the holding portion 44 of the plate 41, the ejector pin hole 47, the cooling hole 48, the gate hole 60, and the runner hole 61; The parting shape synthesis data is stored in association with each other.

  Completion data generating means 35 includes data generated by combining thin data and mold parting data by data combining means 34, ejector pin holes 47, cooling holes 48, gates input by mold shape data input means 12. By combining the mold shape data representing the shapes of the hole 60 and the runner hole 61, the completion data of the design object is generated.

  FIG. 11 is a flowchart showing an example of operation processing of the design support apparatus 1 according to the second embodiment of the present invention. FIG. 12 is a diagram showing a data shape for split shape synthesis. FIG. 13 is a diagram showing a parting data shape. FIG. 14 is a diagram for explaining a synthesis process of data obtained by synthesizing thin wall data and mold parting data and mold shape data.

  In FIG. 11, the operation processing of the design support apparatus 1 is started in step b0 when the mold 40 is designed as a design object, and proceeds to step b1. In step b1, when designing the mold 40, the mold base data designer inputs mold base shape data input to the mold base data input means 11, specifically, plate data representing the shape of the plate 41 and the holding unit 44. The parting shape synthesis data, which is the holding unit data representing the shape of, is acquired. At this time, the mold base data designer determines the dimensions of the mold base and the mold part 51 in advance based on the external dimensions of the product 50 to be molded, and the mold base based on the predetermined dimensions. Create shape data. However, if it is necessary to change the dimensions due to subsequent product shape changes or molding machine conditions, corrections are made at that time. If mold base shape data is acquired, it will progress to step b2.

  In step b2, as shown in FIG. 12, based on the mold shape data representing the shapes of the ejector pin hole 47, the cooling hole 48, the gate hole 60, and the runner hole 61 inputted to the mold shape data input means 12. In addition, the design relating to the arrangement of the ejector pin hole 47, the cooling hole 48, the gate hole 60 and the runner hole 61 with respect to the plate data and the parting shape combining data acquired in step b1 is performed, and the process proceeds to step b3. FIG. 12 shows a data shape for split shape synthesis in which the arrangement of the gate hole 60 and the runner hole 61 is designed.

  In step b3, as shown in FIG. 12, the first gate hole position data representing the gate hole position 62 designed for the plate data and the parting shape synthesis data in step b2 is obtained as mold base data storage means. 13 is stored. When the first gate hole position data is stored, the process proceeds to step b4.

  In the initial stage of mold design, product data representing the shape of the product 50 is usually also in the middle of development, so if the parting data is not created using the product data in the middle of development. There are many. For this reason, the mold base data designer proceeds with the design work as a preliminary study. Design work as a preliminary study is performed as follows. Based on the parting shape synthesis data and the product data in the middle of development, the holding part 44 and the parting that represents the shape of the product in the middle of development are assembled, and the assembled holding part displayed on the display unit 36 44 and the layout of the ejector pin holes 47, the cooling holes 48, the gate holes 60, and the runner holes 61 are tentatively designed while confirming the shapes of the molds and the molds that are in the middle of development. Arrangement data of the ejector pin hole 47, the cooling hole 48, the gate hole 60, and the runner hole 61 created by the preliminary design work is stored in the mold base data storage means 13.

  In parallel with the tentative examination design work by the mold base data designer, the product design work by the product designer is advanced, and product design completion data (hereinafter sometimes referred to as “product data”) is created. In step b4, the created product data is acquired and stored in the mold base data storage means 13. When the product data is stored in the mold base data storage means 13, the process proceeds to step b5. In step b 5, the parting data input by the parting data input unit 21 is acquired by the mold base data designer and stored in the parting data storage unit 22. When the parting data is stored in the parting data storage means 22, the process proceeds to step b6.

  In step b6, the layout design of the gate hole 60 is performed on the parting data acquired in step b5, and as shown in FIG. The two gate hole position data is stored in the parting data storage means 22. When the second gate hole position data is stored in the parting data storage unit 22, the process proceeds to step b7.

  The mold data design may be performed by a mold base data designer, but may be performed by a mold data designer who specializes in designing mold data. In this case, the design work of the preliminary study by the mold base data designer and the design work of the parting data by the parting data designer can be performed in parallel, and work efficiency for the design work of the mold 40 is improved. Can be improved.

  When the parting data is created, the mold base data designer moves to the work of synthesizing the parting shape synthesis data and the parting data. In step b7, the data composition calculation processing unit 30 reads out the parting shape composition data stored in the mold base data storage means 13 based on a command from the mold base data designer. When the parting shape synthesis data is read, the process proceeds to step b8.

  In step b8, it is determined whether or not old composite data, specifically, parting data has been combined with the parting shape combining data read from the mold base data storage means 13, and if it has been combined, step b9. If not, the process proceeds to step b10. When the parting data is created for the first time, the parting data is not composited with the parting composition data read from the mold base data storage means 13, so the process proceeds to step b10. In addition, when the shape of the product 50 is updated due to a design change or the like, and the parting data is created accordingly, the parting data for the parting shape synthesis and the parting data are combined before, so the step Proceed to b9.

  In step b9, the old composite data deletion means 31 uses the data obtained by combining the old part split data and the part split shape composition data input before the part split data input means 21 newly inputs the part split data. , Delete old mold split data. When the old mold split data is deleted, the process proceeds to step b10.

  In step b10, the thinning processing means 32 applies the shape represented by the remaining parting shape combining data of the data from which the old parting data has been deleted by the old composite data deleting part 31 to the holding part 44 of the plate 41. The mold split shape composition data is deformed so that only the part that comes into contact, more specifically, the part that comes into contact with the cavity side holding part 45 of the cavity plate 42 and the part that comes into contact with the core side holding part 46 of the core plate 43 remains. Is thinned to generate thin data.

  In step b13, which will be described later, when two different data, specifically, the parting shape synthesis data and the parting data are combined by performing an OR operation, the shape represented by the parting data as shown in FIG. When the concave portion is included in the shape represented by the combined data generated by combining the parting shape synthesis data and the parting data by the logical sum operation, There is a problem that the shape cannot be reflected, in other words, the shape represented by the combined data cannot be a shape including the concave portion. Therefore, in this embodiment, in order to solve the problem that the shape represented by the composite data cannot reflect the shape of the recess included in the shape represented by the parting data, as shown in FIG. Thin data is generated by performing thinning processing on the split shape synthesis data, and the generated thin data and mold split data are combined by logical sum operation to generate composite data. As a result, when thin data and parting data representing the parting shape having the shape of the recess are combined by logical sum operation, the combined data generated by combining is included in the shape represented by parting data. The shape of the recessed portion to be reflected can be reliably reflected.

  Specifically, in the thinning process in step b10, the mold base data designer inputs a processing command prepared in advance to execute a thinning process such as a cut command or a thinning command, and the thinning process is performed. You may make it perform by giving the command for performing a process to the data composition calculation process part 30. FIG. When the thinning process is performed, in order not to depend on the shape of the mold split, for example, the thickness dimension is set to 0.1 mm so that only the portion contacting the holding portion 44 of the plate 41 is deformed to remain thin. What is necessary is just to perform a thinning process. In step b10, after thinning processing is performed on the parting composition data, the process proceeds to step b11.

  In step b11, the data composition calculation processing unit 30 reads out the parting data stored in the parting data storage unit 22 on the basis of a command from the mold base data designer. When the parting data is read, the process proceeds to step b12.

  In step b12, the alignment means 33, based on the thin data generated by the thinning processing means 32 and the parting data read out by the data synthesis arithmetic processing part 30, the holding part 44, the parting 51, Perform the alignment process. At this time, if a coordinate system for the reference position of the mold base is created for the holding unit 44 related to the thin data and the mold part 51 related to the mold data, the coordinate system is assembled to match the coordinate system. By performing the above, alignment can be performed easily. When the alignment process is performed in step b12, the process proceeds to step b13.

  In step b13, the data synthesizing unit 34 synthesizes the thin data generated by the thinning processing unit 32 and the parting data read from the parting data storage unit 22 by, for example, a logical sum operation. The thin data and the parting data are synthesized by the logical sum operation as follows.

  In the data composition unit 34, a predetermined coordinate point of the coordinate system created when the alignment by the alignment unit 33 is performed may be expressed as a virtual solid represented by the thin data (hereinafter simply referred to as “thin virtual solid”). ) And whether or not the predetermined coordinate point exists inside the mold part 51. When the data composing unit 34 determines that the coordinate point does not exist in either the thin virtual solid or the mold part 51, composite data generated by compositing the thin data and the part data is generated. It is assumed that the coordinate point does not exist within a solid represented by (hereinafter, simply referred to as “synthetic solid” in some cases). Further, when it is determined by the data synthesizing unit 34 that the coordinate point is present in at least one of the thin virtual solid and the mold part 51, the coordinate point is present in the synthetic solid. . In this way, a composite solid is created by connecting the coordinate points determined to exist inside the composite solid.

  More specifically, when performing the logical sum operation, the first input value is represented by the numerical value “1” when the predetermined coordinate point is present inside the thin virtual solid, and is represented by the numerical value “0”. To express. Further, as the second input value, a case where the coordinate point exists inside the mold part 51 is represented by a numerical value “1”, and a case where the coordinate point does not exist is represented by a numerical value “0”. In the logical sum operation, when both the first input value and the second input value are the numerical value “0”, the numerical value “0” is output as the output value, and the first input value and the second input value are When at least one of them is a numerical value “1”, a numerical value “1” is output as an output value. Here, when the output value is a numerical value “0”, it indicates that the predetermined coordinate point does not exist inside the composite solid, and when the output value is a numerical value “1”, the predetermined coordinate point is Represents the presence of a synthetic solid. When the thin data and the parting data are combined in step b13, the process proceeds to step b14.

  In step b14, the completion data generating unit 35 combines the data generated by combining the thin data and the parting data with the data combining unit 34 and the mold shape data by a logical product operation, so that the design object Generate completed data. Here, the mold shape data represents the shapes of the ejector pin hole 47, the cooling hole 48, the gate hole 60 and the runner hole 61 inputted by the mold shape data input means 12, and the ejector pin hole 47, the cooling hole 48, the gate. The dimension of the shape of the hole 60 and the runner hole 61 includes the dimension of the mold shape represented by the synthesized mold data.

  Originally, the mold shape data representing the shapes of the ejector pin hole 47, the cooling hole 48, the gate hole 60 and the runner hole 61 input by the mold shape data input means 12 and the mold base shape data input means 11 are input. After performing the process of combining the parting shape synthesis data, the thin data generated by thinning the combined data and the parting data are combined by OR operation. Complete data should be generated, but if such a composition process is performed, the ejector pin included in the shape of the thin data is added to the shape represented by the composite data generated by combining the thin data and the parting data. There arises a problem that the shapes of the hole 47, the cooling hole 48, the gate hole 60, and the runner hole 61 cannot be reflected.

  Therefore, in the present embodiment, the shape of the ejector pin hole 47, the cooling hole 48, the gate hole 60, and the runner hole 61 included in the shape of the thin data cannot be reflected in the shape represented by the composite data. Therefore, after performing the mold base data input process, the logical sum operation process is performed, and thereafter, the data generated by the logical sum operation process and the mold shape data are combined by the logical product operation. To. Here, the mold shape data represents the shapes of the ejector pin hole 47, the cooling hole 48, the gate hole 60 and the runner hole 61. The dimensions of the shapes of the ejector pin hole 47, the cooling hole 48, the gate hole 60 and the runner hole 61 are as follows. , The size of the shape of the parting represented by the parting data to be synthesized is included. As described above, after performing the mold base data input processing, the logical sum operation processing is performed, and then the data generated by the logical sum operation processing and the mold shape data are combined by the logical product operation. Thus, the shape of the ejector pin hole 47, the cooling hole 48, the gate hole 60 and the runner hole 61 included in the shape of the thin data is added to the shape represented by the composite data generated by combining the thin data and the parting data. It can be reflected.

  Further, based on the first gate hole position data stored in the mold base data storage unit 13 in step b3 and the second gate hole position data stored in the parting data storage unit 22 in step b6, as shown in FIG. Then, a difference value D between the gate hole placement position 62 designed for the plate data and the parting shape combining data and the gate hole placement position 63 designed for the parting data is obtained. Then, based on the obtained difference value D, the gate hole 60 is moved to the arrangement position of the gate hole 60 displaced by the design change accompanying the change of the product shape. Thereby, the arrangement position of the gate hole 60 can be corrected. If the data representing the shape of the runner hole 61 and the data representing the shape and arrangement position of the gate hole 60 are stored in association with each other, the arrangement position of the runner hole 61 is data representing the shape of the runner hole 61. It can be easily changed based on the data representing the shape and arrangement position of the gate hole 60 stored in association with each other.
