In manufacturing this press-molded product, a press mold is designed according to the shape, and a press mold is manufactured for each product.

  This press die will be described by taking a punching die as an example. The design of this punching press mold has conventionally originated from the basic mold plate. For this reason, it is necessary to design each part and design element necessary for the design one by one, and the design is complicated and it takes a considerable time to design even a skilled designer, and the design is simple. Couldn't do it. Therefore, recently, a front view incorporating various plates as shown in FIG. 30 on a CD-ROM, a diagram showing a die set composed of a punch holder and a die holder as shown in FIG. The basic structure of a press mold with typical parts attached as a basic structure is a drawing of the plate inserted between them, and the data has been proposed to assist the design of the press mold. ing.

  In FIG. 30, reference numeral 100 denotes a basic structure of a press mold, 110 is an upper mold, 120 is a lower mold, and the upper mold 110 and the lower mold 120 constitute the basic structure 100 of the press mold.

  The upper mold 110 is provided with a punch holder 111, a punch backing plate 112, a punch plate 113, and a stripper plate 114. Further, the lower mold 120 is provided with a die holder 121, a die backing plate 122, and a die plate 123. The upper mold 110 and the lower mold 120 are assembled using a die set guide post set 130 as shown in FIG. 31 to form a basic structure 100 of a press mold.

  The punch plate 113 of the upper mold 110 is a plate for attaching a punch (not shown), the punch backing plate 112 is a plate sandwiched between the punch plate 113 and the punch holder 111, and the stripper plate 114 is a product to be processed. It is for holding down.

  Reference numeral 140 denotes a tightening bolt for attaching the punch backing plate 112 and the punch plate 113 to the punch holder 111.

  Reference numeral 160 denotes a stripper bolt for attaching the stripper plate 114 to the punch holder 111.

  170 is a spring for the strip plate 114 to strongly hold the product.

  The die plate 123 of the lower mold 120 is used to place a product to be pressed, and is attached to the die holder 121 with a fastening bolt 180 via a die backing plate 122.

  The die set guide post set 130 is attached to the bush 131 attached to the punch holder 111 of the upper die 110, the guide post 133 attached to the washer 134 fitted in the die holder 121 by the fastening bolt 135, and the tip of the guide post 133. And the ball retainer 132 to be formed. The upper mold 110 and the lower mold 120 are assembled by the die set guide post set 130.

  As shown in FIG. 33, the punch holder 111 constituting the upper mold 110 has a plan view stored in the CD-ROM in a state where main machining elements (machining holes in FIG. 33) are shown in advance.

  Further, as shown in FIG. 34, the punch backing plate 112 constituting the upper die 110 has a plan view of the upper die 110 in a state where main machining elements (machining holes in FIG. 34) are shown in advance. As shown in FIG. 35, the punch plate 113 shown in FIG. 35 has a plan view in a state where main processing elements (processing holes in FIG. 35) are shown in advance, and the stripper plate 114 constituting the upper mold 110 is shown in FIG.

  In such a conventional press die design using a CD-ROM as shown in FIGS. 30 to 39, only representative parts are displayed. The design elements are insufficient, and the design of the press die is not perfect, and parts necessary for the design and the design elements are missing.

  Therefore, when designing a press die, the designer of the press die must newly design and add parts necessary for designing the basic structure as shown in FIGS. 30 to 39 and design elements thereof. . However, in the conventional design of a press die using a CD-ROM as shown in FIGS. 30 and 31, the design shown in FIG. 30 is a front view of the basic structure of the press die and is shown in FIG. 30 is an assembly of the upper mold 110 and the lower mold 120 in FIG. 30, in which various plates inserted between the punch holder 111 and the die holder 121 are omitted, and the basic structure of the press mold is shown. The components shown are arranged and displayed on the same plane. For this reason, the positional relationship between a representative part and its design element in an actual press die is not clear.

  Therefore, even if a part necessary for designing a press die other than the representative part already attached to the basic structure shown in FIGS. 30, it cannot be directly written in FIG. 31 of the assembly drawing, and even if parts and design elements necessary for the design of the press die are newly designed and added to FIG. 30 and FIG. , Representative parts already installed in the basic structure shown in FIG. 31 and their design elements, and the positional relationship between the newly designed parts and the necessary parts added to FIGS. 30 and 31 and their design elements This is not clear, and it does not mean that the press die design has been completed.

  Moreover, in the design drawing showing the basic structure of the conventional press die, FIG. 30 is a front view, FIG. 31 is only a drawing using the assembly drawing of FIG. 30 and parts supplied by a specific manufacturer, and can be seen in FIG. Since the parts supplied by a specific manufacturer incorporated in the basic structure are shown on the front view, when designing the press die, each plate shown in the basic structure as shown in FIGS. Necessary parts and their design elements are written and newly drawn, or part of FIG. 31 is rewritten to clarify the positional relationship between representative parts and their design elements. In addition, in the design of a conventional press die using a CD-ROM, parts necessary for the design of the press die other than the representative parts incorporated in the basic structure and the design elements (need to be added) (Parts and their design elements) will be written on these drawings and processed elements will be added to each plate, and what kind of dimensions will be used for the necessary parts to be added and their design elements In addition, it is necessary to specify the design drawing so that the design drawing shows the component mounting state in a plan view. Therefore, it is impossible to specify on the drawing where the component is to be mounted when writing.

And design conditions have changed, not can only design of the press die 1 with parts shown in FIGS. 6 to 12, will require more parts.

  In this case, although not shown in the present embodiment, a necessary standard part and a processing shape element (part attachment processing pattern) necessary for incorporating the standard part into the press die are one attachment part. As such, the optimal unit parts are selected from the unit parts that are unitized in an inseparable state and databased as unit parts. In addition, the processing shape elements (part mounting processing patterns) required to incorporate the necessary standard parts into the press mold are unitized into inseparable states as if they were one mounting part, and databased as unit parts.

Yes. For example, if it demonstrates using the bolt nut shown in FIGS. 1-3, FIG. 1 will comprise the unit part which combined the process shape element with the bolt nut, and among these unit parts of FIG. If the processing shape element is erased, as shown in FIG. 3, only the processing shape element is shown. If the processing shape element is deleted from the unit parts shown in FIG. 1, only the standard part is shown as shown in FIG. That is, any of the standard parts of the bolt nut unit unit illustrated in FIG. In addition, the standard part is deleted from the unit parts shown in FIG. 1, leaving only the machining shape element, and a standard part of another size extracted by removing only the machining shape element from FIG. 1 is fitted into this machining shape element.
