Description

A METHOD FOR SUPPORTING DESIGN OF MOLD PARTS AND A SYSTEM THEREFOR}

The present invention relates to a standardization system for processing specifications when selecting and adding secondary parts of a mold part including a mold base or a die set, and in particular, it is possible to easily order mold parts including secondary parts. The present invention relates to a design support system that can reduce mold delivery time.

Due to the recent rapid development and diversification of electronic devices, the shortening of the development period is urgently required, and the improvement of the precision of mold manufacturing of plastic molded parts and the reduction of design time are required. As an effective means to shorten the production period of the mold, there is a standard mold base that is standardized by each manufacturer of the mold and marketed by a professional manufacturer, and the use of the standard mold base in shortening the development period of the plastic molded article is omitted. It is becoming an impossible means and its importance is increasing.

Although the details will be described later, the mold base is composed of a plurality of blocks in which a plurality of steel sheets are combined, and the blocks are guided and guided by the guide parts to slide.

The steel sheet constituting the mold base is subjected to a variety of hole processing and a plurality of attachment part attachment holes called mold parts as additional processing.

In many cases, the mold parts are assembled into a mold base and delivered.

A mold maker (also referred to as a user), also commonly referred to as a mold maker, performs processing on the cavity and core directly related to the shape of the molded article, and weaves it into a general-purpose mold base to complete the mold.

In order to efficiently process the cavity and core, the user's own machine has many special machines mainly for electric discharge machining, wire cut, precision boring, etc.

Mold bases and mold parts are usually purchased from specialized manufacturers of mold bases and mold parts.

These mold bases and mold parts are determined by the shape of the product to be molded, the number obtained, the gate type (runner shape), and the like, and the plate thickness of plates such as the template used for the mold base. In relation to the planar shape and arrangement, the type, quantity, coordinate position, etc. of mold parts such as ejector pins are determined.

As a user, depending on the shape of the product on the mold base as described above, additional processing such as perforation and engraving of individual molds are also performed, and when the supplied mold parts are attached to the mold base, they are delivered from a professional manufacturer. You can concentrate on making the core.

Ideally, the finished cavity core is inserted into the mold base for further processing and the mold parts are attached, and adjusted and polished to complete the mold.

Further processing of mold bases and general-purpose mold parts often results from the use of general-purpose machines such as opening a hole, cylindrical grinding inside and out, and planar cutting and grinding, which are often disadvantageously profitable for the user's hourly wage.

Further, further processing by the user after the delivery of the mold base or the mold part is disadvantageous on the manufacturing schedule of the mold.

Therefore, it is considered that the mold base or the mold parts are additionally processed by a professional manufacturer, and the user is required to supply the mold bases for further processing and mold part completion, which is advantageous in terms of cost and manufacturing schedule.

Here, a general description of the mold base is given. The mold base is considered to be a holder for the cavity (cavity) and the core (solid part) to be a mold, and forms a cavity on the fixed side (block) and attaches the core to the movable side (block). When the mold base is closed and both fixing surfaces on the movable side and the movable side are brought into contact with each other, the space formed by the cavity and the core becomes a mold part of the molded article, and the molten resin is injected therein. When the temperature decreases and the resin solidifies, the molded base is opened to separate the fixed side and the movable side, and the molded resin is extracted by extracting the solidified resin.

The structure of the mold base is composed of a fixed side, a movable side, and several other blocks by overlapping a plurality of steel plates and combining them with bolts as described above, and sliding and guiding and fixing the guide members attached to each block. Even if the movable side moves with respect to the side, the plane position between the two blocks is not misaligned. Therefore, the mold base is composed of a group of steel sheets collectively referred to as a plate, cylindrical columns such as guide pins, cylindrical bearings such as guide bushes, and parts such as bolts.

In addition, mold parts having various uses such as ejector pins (sleeves), positioning rings, spring bushes, support pins, return pins, and flabolts are inserted into the mold base as accessory parts.

The mold base may be said to be composed of a flat steel plate collectively referred to as a plate and an accessory mold part collectively referred to as a part.

Hole processing for fitting the parts into these plates is necessary. In addition, holes such as cooling, manual work, heater holes, and mounting screw holes of the eye bolts for mold hanging are also necessary for the function of the mold base. These require processing of various round holes in the plates constituting the mold base.

In addition, there is a demand for processing a release hole or a (bottom attached) pocket hole other than the lower hole of the cavity notch and the round hole for core attachment, but it is included in the hole processing in a broad sense.

Therefore, the main agent of the service provided to the user from the specialized manufacturer supplying the mold base or the mold part is the mold base, the supply of the mold part, and the hole processing of the plates forming the mold base. In other words, the service may be thought of as being divided into three types: plate, component, and hole (processed in the plate).

In addition, in this specification, the mold base as an assembly, the steel plate (guide post, guide bush, etc.) guide member which comprises a mold base, and the metal mold | die parts attached to a mold base are named generically, and are called "mold parts."

Further, for example, a mold part (part) may be additionally processed in part, such as a single folding machine for adjusting the overall length of the pins, a change in the mounting hole position, and the like.

Applicant sells a standardized mold base independently as a specialized manufacturer of mold parts, and the applicant's standard has become almost an industry standard due to the track record of responding to the demands of a manufacturer of plastic molded parts for a long time.

In addition, as for standard mold parts of the plastic mold, each plate, a guide pin, a return pin, a guide pin bush, a positioning ring, a spacer, etc. are prescribed | regulated to JIS, and the convenience of use becomes more favorable.

Standard mold bases, which are commercially available from specialized manufacturers, are designed to reduce mold periods from designing molds for plastic molded parts to mold molding, and to facilitate mold design by mold makers as users. Standardize the additional processing, standardize the mold base, parts, and additional processing (product name and symbolization of the processing) to create what can be called a catalog standard, and the user can specify product name symbols, such as the standard mold base described in the catalog specification. It is possible to order a standard mold base by instructing product specifications mainly made up of.

For example, in the case of the present applicant, the catalog specification is divided into three parts, a (standard) mold base, a mold part (moulding part), and an additional machining. The standard mold base page has a 2-plate type and 3-plate. Type, cassette type, and surface type, and the two plate type is divided into high rigidity type, conventional type, and large type.

The structure of the standard mold base is described together with the description of the standard of the high rigidity type of the two plate type.

The standard mold base of the high rigidity type of the two plate type is shown in Figs. 12A and 12B. The mold base is fixed side attachment plate (T), fixed side template (A), stripper plate (S), movable side template (B), support plate (U), spacer block (C), upper ejector plate (E), lower part It consists of a laminated structure of the ejector plate (F) and the movable side attachment plate (L), and for fixing the guide bushes (GBA, GBB), guide pins (GPA), return pins (RPN), and each member between them. Consists of fastening bolts of each size.

The user first selects the plate type and the high rigidity type or the conventional type from the shape and the like of the product to be molded into the mold.

For example, assuming that a two-plate type high rigidity type is selected, a description will be given of a method of instructing the product specification according to the order of the item name symbol when placing an order.

2 Select the plate type and then select the presence or absence of the stripper plate (S) and the backing plate (U) (for example, the backing plate (U) "with", the stripper plate (S) "no" with SA), and then The nominal size (width of the template A and B, for example, 1515 if the width is 150 mm) is selected. Next, the thickness of the fixed side template A, the movable side template B, and the spacer block C, the width of the attachment plates T and L, and the thickness of the support plate U (for example, A = 30). Mm, B = 30mm, C = 60mm, T = 200mm, U = 30mm), the specifications of the ejector plate and the optional specifications or additional machining are to be described continuously. An example is as follows.

`` MDC SA 1515 30 30 60 S V B N ''

Then, N is followed by an option specification or additional machining instruction.

In the case of mold parts, the diameter, length, material, etc. of the ejector pins (sleeves), angular pins, runner lock pins, positioning rings, mold opening control parts, base spacers, springs, and insulation plates are indicated and symbolized. It is possible to visually grasp the order of the mold.

Further processing can be performed by hand, oil hole, heater hole, pocketing, eye bolt screw hole processing, plastic bolt, support pillar, stop pin, stop ring, ejector guide pin, spring, ejector rod, mold lock, position Assembly of fixing ring and sprue bush, processing of mounting hole and mounting U groove, machining of clamp and clamp groove, processing of ejector rod hole, processing of special guide type, addition of return pin hole, change of support pin color , Processing of mold base for insert molding, change of attachment plate size and attachment method, change of plate thickness and plate thickness tolerance, change of material of plate, change of length of parts, machining of guide hole of guide pin, Changing the length of the guide bush, changing the thickness of parts, changing the pitch of parts, changing the pitch and number of fastening bolts, etc. It is.

In addition, in the case of performing additional processing for selecting a mold part and attaching it to the steel sheet constituting the mold base, it is possible to assemble and store the part, to deliver it without inserting it, or to select something and also designate it as a symbol.

Professional makers of standard mold bases can easily process standard mold bases on production lines by deciphering preferences when ordered in this way. However, due to the diversification of mold-formed products (for example, the number of items in the applicant's specification is 20 million or more), the increase in the number of options of the optional specification greatly increases the number of characters in the product name symbol and the advantage of the product name coding. This weakens.

Since the 1980s, design and manufacturing by CAD / CAM (computer aided design / computer aided manufacturing computer-supported design) have become common, and users can design a mold by CAD and then look at the catalog specification. The specification has to be encoded. Therefore, in order to cope with the computerization of the mold design, the present applicant improved the standard mold base, its parts, and the order (order) system for processing in the early 1990s, and greatly shortened the period from order to delivery. (Details: "Futaba Standard Mold Mold Parts Blue Book" VOL.1 Futaba Denshi Kogyo Co., Ltd. published in August 1998 and Supplementary Guidebook Supplementary Edition, July 2000 Futaba Denshi High School Co., Ltd. See the publication of Kaisha).

The standard mold base ordering system is a design / purchase business support tool distributed to customers (hereinafter referred to as a design support system), and the business support software `` molded ring '' (registered trademark of the applicant) By supporting the concept design of the standard mold base by supporting a mold concept design with a three-dimensional solid base (see http://futaba.co.jp/jp/product/mold/product for details), This makes it possible to shorten the mold manufacturing lead time by speeding up the arrangement. The design support system is in the form of instructing the product specification mainly based on the product name symbol of the standard mold base that the applicant has been striving for a long time in the catalog standard.

Moreover, the same idea catalog which centered on the die set for press dies is also published about a press die.

13 is a flowchart showing a process from mold design to mold completion using the standard mold base by the design support system.

A user who is a mold maker performs a product design using CAD (step S1). Next, mold design (cabine core design) is performed (step S2). At this time, the generated CAD data is converted into a CAD intermediate file in IGES format, which is a data format, or DXF format for 2D CAD, SAT format, STEP format, or STL format for 3D CAD (step S3). When the user starts the design support system and reads the CAD intermediate file, the design support system automatically presents the standard mold base specification recommended on the screen (step S4).

The user changes the standard mold base to which the system is being promoted, determines the specification of the standard mold base (step S5), indicates additional specifications (step S6), if necessary in step S5, the Internet, etc. The design data based on the standard mold base in which the design support system was generated is transmitted to the mold maker via the communication line in step S20.

The professional maker side uses the design support system of the professional maker side to estimate and order processing (step S21), processing interference check (step S22), and process information generation (step S23). Then, the mold base processed by ordering the production line is processed (step S24), the processed mold base is delivered (step S25), and the process proceeds to step S11.

The user performs further processing in step S6, and then the design support system converts the generated file into the CAD data format used by the company, and receives the mold base shape data of the standard processing corresponding range from the CAD system. (Step S7), and perform the specification design outside the standard processing corresponding range (step S8), and determine whether modification of the standard mold base or additional specification conforming to the standard is occurring (step S9), If no specification correction is necessary, the process proceeds to step S10, and when the mold design is completed and specification correction is required, the process returns to step S5.

When the mold design is completed and the mold base ordered is delivered, additional processing outside the standard processing range is performed to the mold base in step S11, and the cavity core manufactured separately by the user is inserted in step S11A. The mold is completed (step S13) by finishing and adjusting the mold (step S12).

In order to cope with the various high-level additional processing accompanying the mold production among the precision of plastic molded products, the user has to decide whether the processing corresponds to the current product designation method by a professional manufacturer. Even if they were responding, the number of instructions increased, and the item code became very complicated and verbose, making it difficult for customers to understand and error-prone.

In addition, since the design support system of the mold by the standard mold base is limited to the processing specification which is encoded as a catalog standard of the mold maker providing the design support system, the design of the mold base cannot be completed.

In addition, in the case of a specialized manufacturer, it was not possible to respond quickly to a new processing specification because it required a lot of time and number of steps in preparation period for encoding the processing specification and issuing a catalog.

In addition, processing specifications which are not enumerated as the present applicant's catalog standard include many specification-determining elements as compared with conventional processing specifications, such as a slide core. Such processing specifications need to be over 20 parameters (100 characters or more in the number of characters) for the processing specification expression, and this clearly deviates from the purpose of expression that is easy to understand for humans, which was one goal of the conventional coding. . Therefore, there is a situation in which catalog standardization of slide core processing is difficult to be performed. In addition, the specification description on the catalog also requires many pages, and it becomes difficult for the customer to understand the specification.

Convert a file consisting of the standard mold base and additional specification instructions selected by the design support system, read it into a commercial CAD system, and then redesign if changes to the standard mold base or additional specifications instructed by the design support system are needed. It was necessary to return to the support system, reselect the standard mold base or additional specifications, and re-deliver the commercial CAD system design data.

In addition, since the transmission of design information (ordering report) is sent to the processing and processing step in one step, there is a problem that it is not possible to cope with further processing request by sending the ordering information from the user side again.

Accordingly, the present invention provides a mold design support method and system for mold parts mainly based on the size, position, and attribute indications of parts and processing shapes without regard to the name of the product. It is aimed at contributing to cost reduction and short delivery time in the mold industry.

In addition, the display means displays the name of the mold part extracted from the attribute of the shape symbol, and the correspondence degree in which the attribute and the shape symbol arbitrarily designated are three-dimensionalized or two-dimensionalized.

A method is also proposed in which attribute information held in the shape symbol is selected from an allowable value list based on a professional maker's processing standard, and input is possible as a value within an allowable range based on a professional maker's processing standard. Also, the attribute information held in the shape symbol is read out, the image image displayed on the display means as a three-dimensional shape is changed through the input means, and the result of the change is displayed in the shape symbol when the attribute information on the shape and size is changed. It can be updated as attribute information such as size, and can be changed without returning to a specific dialog. None of the above omits the trouble of inputting numerical values unless there is a problem.

Further, the present invention selectively reads attribute information from all attribute information stored as attribute information of a shape symbol, and generates a data file for price calculation and processing information creation, thereby automating the ordering work or additional processing of a professional manufacturer. It is aiming at vitalization.

The explanation shall be made in the following order.

2. Description of networks in professional makers mainly.

3. Internal structure of the component design method for a mold of the present invention.

4. Explanation of Structure and Property of Shape Symbol

1. Description of flow in designing and manufacturing molding dies with reference to flowcharts.

First, the operational situation of the system to which the component design support method for a mold of the present invention is applied will be described with reference to the flowchart of FIG. 1.

The flowchart is shown including the division of work during the manufacturing of the mold for both the user side as a mold maker and the specialized maker side as a specialized maker of standard mold base and general-purpose mold parts.

In addition, the following description focuses on a mold metal mold | die. When limited to a mold die, a mold base as an assembly, a steel plate constituting the mold base, a guide member, and a mold part attached to the mold base are collectively called a mold part.

In addition, in the following description, the mold component design support system may be called a mold mold design support system.

This die part design support method and system can be applied to die casting dies having the same design concept and having a similar structural structure.

In addition, since the design concept is common, the present method and system for supporting a component design can be applied as it is by applying a die set used in a press mold to a mold base. That is, the die set as an assembly, the steel plate which comprises a die set, the guide member, and the metal mold | die parts attached to a die set are also called and it is called a metal mold | die part, and application range can be extended.

That is, the method and system for supporting a component design for a mold may be applied to a mold mold and a press mold including a die casting mold and the like.

Ordering of mold dies is usually performed by a molder as a mold maker, and a molder is often requested to produce molded parts by attaching a product drawing from an end user. Therefore, the product design may be considered to have already been completed. (S1)

In recent years, shape data of products are often accepted in the form of CAD data. In the design department of a mold maker, it is common to introduce a commercial CAD system and perform mold design.

The model name, capability, and the like of the molding machine used in the molding operation are also generally instructed by the molding company.

The shape data of the product is transferred to the CAD system used by the mold maker, and can be displayed on the display screen of the CAD system.

10A and 10B show examples of display screens. FIG. 10A shows a three-dimensional wire frame image 42 and FIG. 10B shows a shaded display 43. FIG.

In the initial stage of the caviar core design S2, the number of molded articles to be molded simultaneously is determined from the shape data of the product, the capability of the molding machine, and the like. Fig. 11A shows the display screen of the CAD system in the above step, and based on the shaded display 43 of the product, a cavity basic shape 44 almost circumscribed is determined, and the fixed side template is arranged by arranging the number of molded articles to be molded. The state in which the work area 45 is obtained is shown. 6 are shown in the figure.

Next, the basic structure (form) of a mold die, such as a two-piece structure and a three-piece structure, is determined from the gate type and the runner structure. Here, the gate refers to a spout for injecting molten resin into the cavity portion, and the runner refers to a path leading to the resin from the nozzle of the molding machine to the cavity portion. The resin that is injected into this path and solidified is also called a runner, and it is necessary to remove the molded article and the runner from the mold for each molding.

Based on this basic structure, the outline size of the mold base 47 is obtained as shown in Fig. 11B.

At this point, the user's mold mold design support system is started, and the design data is sent to the support system via the CAD intermediate file 12 (S3).

As will be described later, the support system is basically configured to exchange data with a plurality of commercial CAD systems.

In the suggested mold base presentation (S4) of the mold mold design support system, an optimal standard mold base is selected from a mold base standardized on the professional maker side from various values sent through the CAD intermediate file 12, and is called from memory. Presented to the user mold designer.

On the user side, the availability of the standard mold base is examined (S4A), and if available, the standard mold base is selected (S5).

If not available, the specification is determined by the free sized structural mold base (S4B), and the processing specification instruction S6 is made.

In the case of the standard mold base, the professional maker side can enter the first stage of standard processing at the time of ordering by the user.

As one of the features of this support system, a multi-step ordering method is employed for processing the mold base. That is, it is comprised so that processing of a mold base may be processed simultaneously with the progress of a design work by ordering in a several step in the design process of a mold base.

For example, when the order is divided into three stages, the first stage (initial order of 1) is executed at the initial stage of the mold design in which the size of plates such as the mold size such as the outline size and the mold structure of the mold base is determined. do. It is possible to start the process of checking the stock, arranging, appearance, etc. of the plates constituting the mold base and the main parts used.

With the exception of the cavity core periphery, the second stage (intermediate order of 2) is to place an order for specifications such as the engraving of the template to be determined in the middle stage from the first half of the mold design.

The third step is an order of the specification (final order of 3) determined in the final step from the second half of the mold design such as the temperature adjusting hole layout around the cavity core and the projecting pin layout. This determines the overall specifications of the mold base.

By performing the multi-step ordering as described above, it is possible to displace the processing of the mold base, thereby realizing a short delivery time of the standard mold base of the additional processing attachment part and the general-purpose component.

Professional makers can use this mold design support system in various ways such as quotation, process design, NC data generation, and delivery.

Although the detailed description will be described later, the professional maker-side mold design support system 14 can be used to extract the shape symbol to be processed and to refer to the attributes necessary for processing, without obtaining the quotation work or the delivery time response. It is also easy to generate individual NC data.

Since the die shape and mold configuration of the standard mold base become clear in the order specification of the first stage, the quotation and the order processing up to that point are performed (S21). Estimate and outline delivery date are returned to the user through a network such as the Internet (contact 15).

In this step, it is not necessary to check the machining interference, and it is possible to start the mold base machining (S24) through the machining information generation (S23).

If the design specifications of the second and third stages become clear in the machining specification instruction (S6), the machining interference check (S22) is made between the existing holes, for example, perforations for further machining, and ejector pin holes. Consult with user designer. In the same manner as in the first step, the entire processing (S24) of the mold base including the advanced additional processing is performed via the processing information generation (S23).

In the case of a free sized structural mold base, the level of the machining specification instruction S6 corresponds to the second stage ordering. It is inevitable that the process launch will be delayed than the standard mold base.

In addition, in the mold design support system, parts and machining processes newly introduced into standard parts can be added arbitrarily, and are distributed to users from time to time through a network such as the Internet in the form of the latest shape symbol.

In this way, partial additions and changes to the program can be facilitated, contributing to the expansion of the processing range of the specialized manufacturers. The advantage of not having to print and mail a new catalog is also an advantage.

The finished mold base is delivered to the user, and the cavity core is produced on the user side (S11A) and fitted. Next, the mold is completed through mold finishing and adjustment (S12) (S13).

The mold base thus delivered is completed with all the processing specified in the design, and the user side can produce only the cavity and core, and insert the completed cavity and core into the mold base to adjust the mold.

In this method, it is made as a service for the maximum user to accept the design information from the mid-point of the maker's design and to deliver the mold base and mold parts which have completed the entire processing required by the professional maker to the short delivery time.

2. Description of networks within professional makers

Next, the information transfer path of the mold mold design support system will be described with reference to FIG. Fig. 2 is a network diagram mainly including an internal network of the professional maker side for the outline of the information delivery path.

On the user side, dedicated web browsers 21, 21, ... of this system are arranged, and a dedicated web server 22 serving as a reception window of a specialized maker side of the system is arranged via a network such as the Internet.

The dedicated web browsers 21, 21, ... of this system on the user's side transmit the design data of the mold to the dedicated web server 22 and download the latest modules (programs) of the system from the dedicated web server 22. Have

The task of distributing the latest modules of the mold mold design support system to the user and the license management of the user's system is also a window for the dedicated web server 22, which is a task away from the daily ordering work. · It is an important task to develop.

The user can access the dedicated web server 22 and download the latest modules as needed. As described below, these modules are in the form of scripts and Windows DLLs in the object-oriented language Ruby, and can be added to the mold design support system program that the user has previously held.

The processing data created while the user is designing the mold is used organically until the generation of NC tape data for operating the NC machine group at the end of the dedicated maker, and contributes to the efficient operation of the mold base and parts processing in the specialized maker.

3. Internal structure of mold part design system of the present invention

The processing standard control part and shape display part which are used for this metal mold part design system are demonstrated.

In terms of software, the machining standard control unit, which consists of an object-oriented language Ruby script and a Ruby interface (Windows DLL format), uses the machining standard information control program (shape symbol) as the core, and is currently on the market. Consists of a Windows EXE format shape display unit that utilizes its experience in the design support system.

As a hard drive, a so-called personal computer having a CPU, a storage device, an input device such as a keyboard mouse, and a display device such as a CRT is used.

As an example, the machining standard control unit will be described with reference to FIGS. 3A and 3B. 3A is a block diagram of a machining standard control unit and a shape display unit, and FIG. 3B is an explanatory diagram of the properties of Ruby. In addition, detailed description of this language is performed separately.

As shown in Fig. 3A, the machining standard control unit is composed of an object-oriented language Ruby, a Ruby interface, a machining standard information control program, a machining standard data, and a shape display interface.

Machining standard control unit is described in Ruby script, and it is linked with object-oriented language Ruby through Ruby interface and according to Machining standard information control program, internal information of shape symbol based on our Machining standard data (various attribute information such as size, tolerance, material) To provide.

The list of standard parts described in the catalog is all contained in this machining standard control unit. The information on these parts is set for each part as an attribute of the shape symbol, is displayed on the shape display section, and necessary numerical changes can be made on the display.

The shape display unit displays 3D (2D, if necessary). Most of the shape display programs we have already developed and marketed can be used as they are.

The display output of the display processing standard control unit of the shape display unit is displayed as an image through the shape display unit interface in the processing standard control unit.

The Ruby body, Ruby interface, and geometry interface are in DLL format, making it easy to add new programs.

Here, the DLL (Dynamic linking library) format is a function of an operating system such as Windows, and the software routines can be divided into several files, and only those needed can be loaded and used in memory.

In particular, the shape display interface can add a small amount of programs, and in the future, the display of the processing standard control unit can be displayed on the display units of various commercially available CAD systems.

In addition, various additional processing is performed on the mold base, and the item is added or the range is expanded on a daily basis by the user's desire.

In order to inform the user of the additional processing that has newly started the service, relying on the catalog printed as in the past, the creation of the symbol of the additional processing and the printing of the description of the new additional processing require a considerable date and the number of processes. Also, the distribution route of the printed matter is a problem.

If you write only additional processing software that has newly started service in the form of Ruby script and DLL, and distribute only the software to users from a dedicated web server through the Internet, it can be deployed in a much shorter time than before.

The item of "Design system latest module license management" of the function of the dedicated web server of FIG. 2 corresponds to this.

4. Explanation of Structure and Property of Shape Symbol

Professional maker's service for mold maker is to attach mold and its accessories to mold base if mold mold, and all processing for them is completed and delivered, and press mold to die set corresponding to mold base. The processing for them in the form of the attached parts is completed and delivered.

Hereinafter, although description will be given of the mold base main body, it is also commonly used in press dies when the mold base is replaced with a die set.

The mold base may be composed of a plurality of rectangular steel sheets overlapping and fixed with a fixed number of blocks, and installing guide bushes, guide posts, etc., which slide each, to guide each other so as not to change the planar coordinate position of each other.

Various frame parts (e.g., ejector pins, positioning rings, spacers, etc.) are arranged for each element of the plurality of steel plates, and holes for attachment are machined. Hole processing also includes holes for cavity and core attachment.

The service related to the mold base which a professional maker performs is classified into "plate" which shows the said steel plate, "part" which shows other frame parts collectively, and "hole" which generically names the hole processing performed on a steel plate.

The shape symbol describes various attribute information such as size, tolerance, and material of a mold base component (plate, part, hole) by a Ruby script.

In order to form each shape symbol, a symbol Ruby script for holding various property information constituting the shape symbol, and an interface for displaying the size and property information of each part as a dialog on the shape display unit, and setting the value as necessary by the user A dialog Ruby script is used to provide the.

Dialog Ruby scripts, symbols Ruby scripts are constructed by inheritance or reference between several Ruby scripts, as shown in FIG. 3B. You can nest each existing script in turn and create new dialog Ruby scripts and symbolic Ruby scripts. New standard parts can be easily created.

In this way, an efficient program development environment is obtained in such a way that new functions can be added while using existing programs as components.

The shape symbol consists of an attribute class for shape symbols and a basic shape class (primitive).

The attribute class for the shape symbol is a structure that holds various property information such as size, tolerance, and material of each shape symbol part, and is maintained using the Ruby language class structure. By classifying, it is possible to control the behavior between data suitable for the shape symbol. In other words, it is possible to limit the allowable range of certain data or to fix a value under certain conditions from the use indicated by the class.

Each data type of the class is stored in a string.

The attribute classes for shape symbols are divided into three types according to their properties.

The first corresponds to the part name of the catalog in the class name, element (element attribute <plate, part, hole>).

The second is dimensions (reference size, upper limit tolerance, lower limit tolerance), face (machining symbol, finishing precision, cylinder degree symbol), edge (ridge symbol <edge, inside and outside, fillet inside and outside>, right angle, right angle reference length ), Material symbol, heat treatment property, and physical properties such as size, precision, material, and heat treatment.

Third is the origin (placement origin coordinates <sx, sy, sz>, placement angle vector <ax, ay, az>), layout (placement pattern symbol, placement reference plate, layout delivery plate), sweep (sweep flag <sweep sweep) , Rotation sweep,>, rotation angle, reference line <start, end>), wire (reference line <start, end>, straight line, arc <center coordinate, radius>), and to the basic shape class (primitive) described later. This is an attribute related to the assignment of primitives, coordinate positions, etc. in a three-dimensional space, the placement of holes, and the formation of primitives by wire frames.

In addition, dimensions, faces, edges, and the like are also used as third attributes for describing primitives.

By the first "class" of classification, the data and the behavior of the data (such as monitoring of allowable values, the ability to set a value under certain conditions, etc.) can be controlled.

In the second part of the classification, most of the processing conditions are determined. In particular, the machine tool on the face may determine the machine tool used.

In this way, if the second classification for each part (for each class) is determined based on the company's process capability, it is based on the company's machining standards. Not only the size and precision but also the material and heat treatment of standard parts are included.

The "basic shape class" assumes a shape obtained by a three-dimensionally called primitive shown in Figs. 4A to 4E and a sweep of a wire shape shown in (h) (i).

Primitives represent a basic shape in one or a plurality of combinations of primitives in five kinds of three-dimensional shapes of a rectangular parallelepiped, a circumference, a cone, a sphere, and a hemisphere.

In each primitive, the figure origin oA and the vector ve which show the direction of a primitive are defined.

Taking the circumference shown in (b) as an example, an element for determining a symbol shape will be described with reference to FIG. (g), where (f) and details of the respective attributes are shown in a table.

The center of the circle on the bottom is the figure origin (oa), and the vector (ve) is drawn with the upward arrow on the axis line of the circumference.

If the primitive is a circumference, its size can be described by the diameter d1 and height h1 of the bottom circle.

The ridge lines are two of g1 and g2, the planes are three planes of f1 to f3, and it is necessary to describe the five attributes.

The class name of the base primitive class is registered as a "symbol cylinder". Next, the arrangement of the circumference on the three-dimensional space is performed by determining the coordinates of the figure origin oa and the direction of the vector ve as "array coordinates and angles".

The size is size 1, size 2 and is defined by the dimensions d1 and h1.

The ridge attribute selects the chamfer (C or arc to the inside) fillet (extension of C or arc to the outside) by the use of the primitive.

Surface attributes display the state of each face. As mentioned above, the specific conditions of processing are mainly described by this surface property.

As described above, when it cannot be expressed by a single or combination of five kinds of primitives, a shape obtained by a wire-shaped sweep is used as shown in (h) (i).

There are two types of sweeping methods, rotation and sweep, and first define a closed shape connected by a plurality of line segments or arcs on a two-dimensional plane.

In the case of the rotary sweep, a three-dimensional shape obtained by determining a reference axis on the same plane shape and rotating the closed shape at an arbitrary angle around the reference axis is used. For example, when the wire shape of (h) is rotated once, the tab hole shape shown in Fig. 8A is obtained.

In the case of the sweep sweep, a three-dimensional shape in which a trajectory is formed when the closed shape is moved at an arbitrary distance perpendicularly to the plane in which the closed shape is formed (named sweeping) is used. For example, if the wire shape of (i) is stamped a predetermined distance, the hexagonal hole shape of the bolt provided with the hexagonal hole shown in Fig. 6B is hardly seen for the sound ray treatment.

As described above, the shape generated by one or a plurality of combinations of five primitives, such as a rectangular parallelepiped, a circumference, a truncated cone, a sphere, and a hemisphere, or a shape generated by a wire sweeping sweep or a wire sweep sweep Class ".

By defining the shape symbol as a class containing the shape shown by the "basic shape class" and the "property class for shape symbols", the components of the mold base (plates, parts, holes) are subjected to various technical information in accordance with our machining standard. Therefore, it is possible to extract the information necessary for the estimation of the manufacturer, calculation of the delivery date, generation of information for processing, and efficient process management from the shape symbol.

Since the verification procedure for the mold base has already been described, the application example of the parts of the unit will be described.

5 is a part called (color thickness 4 mm full length designation type) in the flat ejector pin from our molded parts catalog.

The pin is used for the purpose of protruding the cross section of the molded article at the thin rectangular tip portion (represented by A × B in FIG. 5B) to remove the molded article molded from the core from the core.

Figure 5a is a side view of the pin, Figure 5b is a front view, Figure 5c is a list of standard products, in the combination of the numbers shown in the tables of A, B, d, D, L, N, the parts with a circle mark is standard It is prepared as a part.

For example, when the tip portion is A = 1.0 and B = 5.0, if N = 50, the total length L corresponds to 70.00 to 125.00 in units of 0.01 mm. Similarly, when N = 60, 70, 80, it shows that it can supply according to the range of L in a table | surface.

The contents of the pages of the catalog are described in the "Characteristic Class for Shape Symbols" of the shape symbol, and the size and size tolerance of each part are described. The heat treatment order to be regarded as the processing standard of the company) is stored in this system.

In order to actually display the pins on the display, a hierarchical dialog box may be called in sequence to reach a dialog block displaying a flat ejector pin (color thickness 4 mm full length designation type). It is easy to select a pin with suitable (size) properties from the dialog box.

The user may proceed with the design arbitrarily without calling the dialog box of the pin.

After the design specifications of the pins have been determined and checked against the system, a search of the flat ejector pins is made and, if there is a standard of the same specification, the corresponding standard is selected. If there is no standard of the same specification, the specification of the similar standard is indicated and if the user agrees, a similar standard is selected.

As for the flat ejector pin (color thickness 4mm full-length designation type) shown in said FIG. 5, arbitrary length can be specified in the range whose total length L is 70-125, for example, when N = 50. This makes it possible to input the selectable range of the total length L as the allowable range value "in the range of 70 to 125 as our processing standard".

On the other hand, although not shown, in the case of a flat ejector pin (color thickness 4 mm type), for example, when the tip portion is A = 1.0 and B = 5.0, the total length L is allowed in four types of 125, 150, 175, and 200. There is a value, and the user can select L from the four types. In other words, the total length L is selected from a list of allowable values of "four types as our machining standard" to enable input.

Even in the same class of A = 1.0 and B = 5.0, the price of the full length designation type is higher.

In this way, the attribute information such as the size held in the shape symbol can be selected as the allowable range value from the allowable value list selectable or selectable from the allowable value list based on the company's processing standards.

If the mold designer who is a user designs the mold part arbitrarily and checks it against this system, if there is a standard part of the specification which is exactly the same as the property of the part, it shows that it is a standard item. If there are no parts with the exact same specification, similar parts are searched for and displayed on the shape display part. If the designer checks the displayed similar parts and selects them, selects them and changes the size of other related parts. If it cannot be used, operation such as making a special order in the initial design state becomes possible.

5. Specific examples of shape symbols (bolts and bolt holes)

In order for the mold designer who is the user to recognize the shape symbol and to access the data change, a dialog box is displayed on the display screen of the shape display unit. As the form of the dialog box, an optimal display form is adopted for each shape symbol.

As an example, referring to Figs. 6 to 8, three steel sheets are provided with various holes (juggling holes, through holes, female threaded holes), and three steel plates are attached by screwing hexagon socket head bolts. The actual usage of the shape symbol will be described in detail. The left side of each figure shows the dialog box image displayed on the screen of a display part as a schematic diagram, and the shape symbol image is shown as a wire frame on the right side.

6A is a representation of a steel sheet used in a mold. The plate is selected as the element property and determines the size, material, heat treatment, surface finish, and the like. The primitive is a cuboid and has a figure origin (oa) in the center of the bottom of the cube. Normally the plate bottom is parallel to the XY plane and the vector ve is parallel to the Z axis.

Specify the size of L, W, and T according to the display of the dialog box. In this example, since three steel sheets are used, input corresponding to each is made in turn.

Usually, in the case of the steel plate which comprises a mold base, the structure of a mold base and its magnitude | size are specified first, and then the use (use name in a mold base) of each board is specified, and material, heat processing, surface completion, etc. are input. The standard size and the like are inputted into the shape symbol according to the plate name of the mold base, and various initial values as standard parts are displayed in the dialog box. In this case, it is only necessary to enter a numerical value that requires a special change.

Fig. 6B is a case where the hexagonal hole mounting bolt is defined. The element attribute is a component, a combination of circumferences as primitives, and a sweep shape sweeping the shape of a regular hexagonal wire as a hexagonal hole. The class name is CSM.

Since the hexagon socket head bolts are standard parts, the specification (catalogue) number, material, surface treatment, etc., are determined by specifying the nominal screw thread length.

The bag length, which is designed arbitrarily as a feature of this system, is compared to the standard, and if there is a standard of the same size, it is selected, and if there is nothing of the same size, the approximate standard of bag length is listed up. It is left to the judgment of the user.

Fig. 7A defines the shape of the hole of the uppermost steel plate, which is a bored bolt hole into which the bolt head enters. The element property is a hole, and the primitive is a combination of two circumferences. HZAGURI is used. On the front and back of the plate is a face clip [CHAMFER EX] which is an edge mark. For the steel plate, determine the coordinates of the origin oa, the placement angle vector, and the size of each part. Because of the hole, the figure origin oa is provided at the top along the machining direction.

Since the steel plate for processing holes is specified, when the inner diameter and depth of the hole and the diameter of the insertion part of the bolt body are specified in the dialog box, the length of the hole having a small diameter is uniquely determined.

Fig. 7B defines the shape of the hole of the intermediate steel plate, and a dialog box appears as a straight hole HSTRAIGHT, where a through hole simply passing through the bolt body is inserted. The element attribute is a hole, and the primitive has a shape where a C plane is cut on one circumference.

Fig. 8A shows a state in which the lowermost steel sheet is a female screw hole, the screw lower hole of the stop hole is opened, and the screw is cut to the middle. The element attribute is a hole and uses a rotating sweep shape in which the wire shape of (h) is rotated once. Only the upper part is made of cotton clipper [CHAMFER EX]. The shape symbol name becomes a screw hole (HTAP). Input of the nominal diameter of the screw, the effective length of the screw, and the length of the lower hole is required. The lower hole diameter is usually determined by the nominal diameter, but is finely adjusted in consideration of the effective diameter of the screw, the material and the hardness of the steel sheet, etc. according to the company's processing standards.

As described above, the determination of the attributes of each component is performed by calling up the necessary dialogs and repeating the operation of substituting the original display portions with specific values.

In FIG. 6A, when the specific size specifications L, W, and T of each steel sheet are inputted on the dialog, the attributes are stored, and the subsequent 3D display screen is displayed as a plate having the input L, W, T. In addition, the hexagonal socket head bolt of FIG. 6B is also stored in its property by input of a nominal diameter and a luggage length, and is displayed in proportion on the subsequent 3D display screen.

In addition, the user reads the attribute information such as the size held in the shape symbols of the steel sheets and the molded parts, and displays an image image displayed as a three-dimensional shape on the display device of the computer. The user inputs a computer input device such as a mouse or a keyboard. When the size, position, placement angle and the like are changed in the three-dimensional space by manipulating, the change result is updated as attribute information such as the size in the shape symbol.

That is, the attribute information can be changed not only on the dialog but also on the 3D display screen, and the result can be stored in the shape symbol. Therefore, the attribute information such as the size can be changed on the 3D display screen without displaying the dialog screen one by one.

Since the hole designation required for each of the three steel sheets is completed, as shown in Fig. 8B, three steel sheets are overlapped to coincide with the axis of each hole and bolts are inserted. Since the holes and bolts are displayed simultaneously, the class name is named HCSM.

In the case where the three sheets of steel are the component parts of the mold base, the positional relations of the three sheets of steel are in a constant relationship, and the bolts are fastened so as not to break the positional relationship. Each of the holes provided in the three sheets of steel sheets may be set at one time in the items of the layout (placement pattern symbol, placement reference plate, placement delivery plate) that specify the XY coordinates of the bolt holes and the position in the Z direction.

In the above, the specific example of using a shape symbol was demonstrated in the simple example. A description of the holes of the three steel sheets is made, specific values are shown, and the size of the hexagon socket head bolt as a mold part and the catalog number of the standard product are determined.

Although the above results were obtained from the number items on the shape of the "Attribute symbol attribute class" and "Basic shape class (primitive)", three items were obtained by subtracting all the items of the "Attribute symbol attribute shape" for each steel plate. All the properties of the plate become clear, including the drilling.

Therefore, shape processing including raw material arrangement and hole processing of three steel sheets whose element attributes are plates becomes possible. Hexagon socket head bolts with element properties are standard parts and can be arranged as a finished product.

The actual mold design is a very long time work, and the complete design of the sheet of steel constituting the mold base is near at the completion of the cavity core design.

However, hole coordinates such as guide posts, guide bushes, and the like are determined at an early stage of mold base selection, and the design of the runner relationship proceeds after the arrangement of the cavity is determined next. The design of holes such as ejector pins that affect the shape of the product to be manufactured is the last in line with the design of the cavity core.

Therefore, if the mold design is made in the mold mold design support system, and the obtained data are properly partitioned and provided, multi-step ordering is possible by the data for design completion.

When a unit structure such as a mold base is designed as a combination of a plurality of shape symbols, each shape symbol in the operation of the system is held in a storage mechanism called a hash provided by Ruby.

The information necessary for converting the shape symbol information into the format for estimation and processing information is selectively extracted from the storage mechanism for use.

Hereinafter, the method of extracting information stored in the hash will be described with reference to FIG. 9.

Regarding the shape symbols held in the hash, as shown in (1) of FIG. 9, a specific shape symbol is designated by continuous access to the symbols of all shapes, and associative arrangement of hashes as shown in (2). Shape symbol information can be acquired freely, such as an access.

Therefore, the attribute information of the shape symbol is accessed, the use (plate, part, hole) of the shape symbol is determined, and the calculation elements necessary for generating the quotation and processing information are obtained. Calculation factors include the use, placement origin, size, material (for plates and parts), machining method (for holes), and the like.

In the case where the shape symbol is a plate or a part, on the basis of the information obtained for the above calculation purposes, a pseudo article name according to the Company's notation method is generated as a pseudo article name with the symbol name as a key. Quotation information according to the quotation form can be generated based on the item name.

If the shape symbol is a hole, plate information to be processed is acquired. This is held in the attribute information at the point of shape symbol arrangement.

Next, for each plate, processing information in a form for processing information according to the company's display method is generated.

The above quotation information and processing information can be used as it is in each sector organically connected by the specialized maker LAN.

6. Relation between general CAD system and part design method for mold

The Ruby body, Ruby interface, and feature interface are in DLL format, which has already been described to simplify the addition of new programs and coordination with existing programs.

When the company releases the procedure using the shape symbol information controlled based on the processing standard as an interface of a DLL for a commercial personal computer OS such as Windows, for example, the shape symbol can be used at any time while using a commercial CAD system. Attribute information of can be used.

In the future, a dialog box or the like may be displayed on the display of a display unit of a commercially available CAD system, and the attribute information of the shape symbol of the mold part design system of this mold can be used directly.

This allows the mold designer, who is a user, to use the CAD system without having to see a separate display section and refer to the standard parts conforming to our machining standards.

In this way, by describing our processing standard as an initial value in the shape symbol of the Ruby system, the same effect as referring to our printed catalog can be obtained. Designers can obtain attribute information of our machining standards while using their CAD system, freeing them from the hassle of turning pages one by one. And if there are no particularly fatal problems, we will choose plate, part, and hole machining according to our machining standard.

As described above, the shape symbol used in the present invention contains various types of technical information as its attributes. Therefore, when a particular type of component is designated, the entirety of each shape symbol belonging to the component is called, and the detailed description is given from the attribute information. You can get information.

Therefore, although the product name symbol is used in the order form of the current catalog, all the product name symbols indicated by the above unique character strings and the sequence of characters until further processing instructions can be expressed as attributes of the shape symbol and do not depend on the product symbol. Processing instructions are realized.

That is, a mold designer who is a user has an advantage of being able to specify a high degree of freedom in the range of processing standards provided by the company without being aware of the name code for placing orders for the company.

In addition, in the catalog, the shape symbol can be used for processing specifications that do not specify the product name code, and it is possible to receive orders as a form of our ordering information through the network, and it is also possible to receive orders not listed in the catalog. .

Also, if the shape symbol has a base value based on our machining standard, and the user changes the size or the like in the three-dimensional space by the user operating the computer input device, the image image displayed on the display device is three-dimensionally displayed, the change result is changed. Therefore, the corresponding attribute information in the shape symbol is updated. In other words, the user may correct only necessary portions as the design progresses.

By providing a user interface that has an initial value based on such a machining standard and whose value can be changed as necessary, machining specification instruction with both a reduction in manpower number and freedom is possible. Reduction of the number of design steps and the hassle of numerical decision increase the designer's satisfaction with this system.

By using these shape symbols as subjects of ordering information, processing instructions based on the company's processing standards can be obtained, thus maintaining a production system capable of efficiently exhibiting the company's production facilities. Machining information such as estimating work and NC tape also contributes to the realization of complete automation without the need for human hand.

In addition, since accurate processing information can be obtained, an integrated production management system that manages the entire plant cross-section is fully functional. As a result, reliable delivery date display can be made to the user based on accurate factory load and production progress information.

Estimate work, automate the creation of machining information, and improve the function of the integrated production management system reduce the number of required processes per case, and can cope with multiple orders in which the design process is divided over time.

In other words, the use of the shape symbol makes it possible to realize a collaborative production system of a mold corresponding to a customer's multi-level order. Shorten the delivery time of mold base and mold parts.

In addition, it is possible to speed up the start of a new machining service. Even without publishing a paper catalog, it is possible to quickly distribute the menu of the latest processing service of the order system through the Internet, etc., and redistribution by correction and improvement is easy. The user has the advantage of being able to employ new processing on the fly.

There is also a vitalization effect that a professional maker can cope with much less effort than the effort required for issuing a conventional paper catalog.

In addition, the company's processing standard information can be displayed on the display unit of the commercial CAD system by the interface disclosure for use of the processing standard information of the commercial CAD system. Designers of mold makers can work with CAD materials they are used to, from product design to mold base design, and a consistent operating environment is available.

Therefore, the use of the processing standard information of the company is carried out without resistance, and the ratio of the information obtained from various commercially available CAD systems to the order information based on the shape symbol that is convenient for the company increases.

On the contrary, when ordering from CAD drawing or CAD data in the format of CAD original output directly from a commercial CAD system, we need a laborious task of creating estimates and processing information by reading or manually inputting drawings. However, if the use of shape symbols increases and the proportion of orders placed using commercially available CAD information decreases, it is possible to reduce the number of commercially available CAD counterparts of the company and reduce the cost.

In addition, the increase in the use of the initial value of the shape symbol on the commercial CAD also has the advantage that the ratio of the standard product can be increased.
