Abstract

PURPOSE:To input a plane form and a sectional form by one product form input operation by associating the plane form with the sectional form correspondingly to one product form name, integrally defining and managing both the forms by the product form name. CONSTITUTION:The plane form PLV of the product and the sectional form SCV of the product are integrally defined and stored in a floppy FLD. The three names of the product form name, the product plane name and the product sectional form name are applied to one product form and the product form is managed by the product form name. For instance, as the product form name, 'TOP', as the product plane form name, 'PLTOP', and as the product sectional form name, 'SCTOP' are applied and they are managed by the product form name 'TOP'.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a product shape management method in a mold design system.

<Prior Art> A mold is composed of a plurality of plates, and a guard core, runner gate, water hole, etc. are provided at appropriate locations. Note that each plate is fixed with bolts and other parts.

In the design of such molds, the following steps have conventionally been carried out: (a) inputting the planar shape and cross-sectional shape of the product; (b) determining whether to make one piece or multiple pieces (two or more); and NC data for mold processing is created according to the layout design that specifies the layout, etc. (Cl mold pace, that is, the general total of the mold itself, and (d) NC data creation).

<Problems to be Solved by the Invention> Conventionally, the planar shape and the cross-sectional shape are regarded as different shapes, and each is given a different shape name. Therefore, in order to input the product shape into the mold design system, you must first perform the specified product shape input operation to input the planar shape, and then perform the same operation to input the cross-sectional shape. There was a problem in that input operations were required twice.

In addition, since the planar shape and cross-sectional shape are treated as different shapes and managed separately, if the operator does not know both the planar shape name and the cross-sectional shape name for a certain product, it is difficult for the operator to know the product shape of the product. There was a problem that it was not possible to input the information into the mold design system correctly.

From the above, an object of the present invention is to provide a product shape management method in a mold design system that can integrally manage the planar shape and cross-sectional shape.

Means for solving the problems> Figure 1 shows a CA for mold design to which the present invention can be applied.
FIG. 1 is a block diagram of a D/CAM system.

11a is a processor, 11C is a RAM, 12 is a graphic display device, 13 is a tablet) device 1.14
c is a floppy drive.

CRT is the display screen, PLV is the planar shape of the product,
SCv is the cross-sectional shape of the product, and FLD is floppy.

Function> The planar shape PLV of the product and the cross-sectional shape SCv of the product are integrally defined in correspondence with the product shape name. Then, the product shape is managed (registration, input/output, change processing, etc.) using the product shape name.

<Example> Figure 1 shows CA for mold design to which the present invention can be applied.
FIG. 1 is a block diagram of a D/CAM system.

11a is a processor, 11b is a ROM, llc is a RAM

4a is a keyboard, 14b is an X-Y plotter, 14C is a floppy drive, and 15 is a large capacity storage device for storing various data files for mold design, automatically created NC information, etc.

In addition, CRT is the display screen, PLv is the planar shape (plan view) of the product, and SCv is the cross-sectional shape (cross-sectional view) of the product.
FLD is floppy.

The planar shape PLV of the product and the cross-sectional shape SCV of the product are defined in advance in correspondence with the product shape name, and the floppy FLD is created.
Remember it. The following is a program example of a product shape definition statement.

(il P A R T , ■ Name (ii) M O D E , G ROU P , ■
Product shape name (ii) MODE, PLANE, ■Product planar shape Gψ [hereinafter, definition of product planar shape] (vlMODE, PLANE, E ■MODE, 5ECT, ■Product cross-sectional shape fvi

T, E GXIMODE, GROUP, E (X)FINI END However, (i) is a command that specifies the program name, fii) is a command that starts defining the product shape and specifies the product shape name, and GiD is the product plane. A command for starting the definition of the product shape and specifying the product cross-sectional shape, (v) is a command to end the definition of the product planar shape, ■ is a command for starting the definition of the product cross-sectional shape and identifying the product cross-sectional shape salt, - Product cross-sectional shape definition end command, Gxl is the product shape definition end command, (branch) is the command that indicates the end of the program.

As is clear from the above program example, three names are given to one product shape: product shape name, product planar shape salt, and product cross-sectional shape salt. Shape is managed.

For example, the product shape shown in FIG. 2 has rTOPJ as the product shape name, rPLT, OPJ as the product planar shape salt,
Although rscTOPJ is attached as the product cross-sectional shape salt, it is managed by the product shape name "TOP".

Now, in order to design a mold with the product shape registered in the floppy FLD, the product shape must first be transferred from the floppy FLD to the RAM 11c.

To do this, pick the "Product Shape Input" item on the menu table 13b with the mouse 13c, and then use the keyboard 14b.
Then input the product shape name (for example, "TOPJ").

By inputting a product shape name, a predetermined planar shape and cross-sectional shape are successively read from the floppy FLD using the product shape name as a keyword and transferred to the RAMIIC.

After that, in order to design the layout, the operator selects the "Layout Design" item on the menu table 13b, and the planar shape PLV and cross-sectional shape S of the product are displayed on the CRT as shown in FIG.
Cv is drawn.

After that, select the "Move", "Copy", or "Invert - 1 "Delete" item on the menu table to move the product position or copy the drawn planar shape or cross-sectional shape to another position. , or by inverting or deleting the products to finally complete the layout design of the desired number of products. If one of the planar shape or cross-sectional shape of the product drawn in this layout design is changed, the other will also change.

Once the layout design is completed, a mold design is performed and finally NG data for mold processing is created.

<Effects of the Invention> According to the present invention, a planar shape and a cross-sectional shape are defined integrally in association with one product shape name, and both shapes are managed by the product shape name. Therefore, a planar shape and a cross-sectional shape can be input by a single product shape input operation, and product shape management has become easier because it is only necessary to associate one name depending on the product.
