Mold component design aiding method and system thereof

Technical field

The present invention relates to add the mold component comprise die ontology (base), module selection, append the standardized system of the processing specification that adds man-hour for 2 times, also relate to order easily and comprise the processed mould parts 2 times, and can shorten the mould design aiding system of delivery date.

Background technology

Follow the development rapidly and the variation of electronic equipment in recent years, be badly in need of the shortening exploitation time limit, the precision of the Mold Making that requirement raising plastic mould is used and shortening design time.Means as effective shortening Mold Making time limit, be that each parts in the mould are carried out standardization, the Standard Module body of on market, selling by the specialized vendor, for the exploitation time limit that shortens plastic mould, what utilize the Standard Module body is indispensable means, and its importance becomes increasingly conspicuous.

Die ontology constitutes in the following manner: the polylith steel plate is connected, constitute according to a plurality of sections (block), this section leads by guiding parts, realize sliding, and this point will specifically describe in the back.

For the steel plate that constitutes this die ontology, append processing and comprise the processing in various holes, and a plurality of appurtenances that are called " mold component " are installed the processing in the hole of usefulness.

In most cases, this mold component is assembled in the die ontology.

Generally, the mold manufacturing industry person (below be called " user ") who is also referred to as " mould manufacturer " carries out the die cavity directly relevant with the shape of moulded parts and the processing of core rod, carries out assembling, the adjustment of general die ontology, finishes mould.

Usually, in order to carry out the processing of die cavity and core rod effectively, the machinery that the user has is most to be with discharge processing, the wire rod cutting, and precision drillings etc. are the special machine of main body, practitioner's time rate wage is also higher.

Die ontology, mold component are usually to die ontology, and the specialized vendor of mold component buys.

These die ontologies, mold component, according to molded shape of products and quantity, gate form (runner gate shape) etc., determine the thickness of slab etc. of the plate class of template that the form, die ontology of die ontology adopt etc., the flat shape of main and goods, the form that disposes the mold component that is associated to determine demoulding pin etc., quantity, coordinate position etc.

As the user, also entrust the said products shape, to die ontology, comprise the additional processing of each mould being carried out different hole processing, the inserting slot of template etc. respectively, if under the state that attached mold component is installed on the die ontology, pay goods from the specialized vendor, then can carry out the die cavity as the industry, the making of core rod specially.

Preferably die cavity, the core rod of finishing is assembled on additional process finishing and the mounted die ontology of mold component, adjusts, grind, finish mould.

In most cases, the additional processing of die ontology and general mold component etc. is that universal machine carries out common perforate, inside and outside cylinder grinding, flush cut, grinding waits and finish by using, in most cases, with regard to user's time rate wage, cost efficient is disadvantageous.

In addition, after paying die ontology, mold component, replenishing processing by the user, also is being disadvantageous aspect the manufacturing schedule of mould.

Therefore, the additional processing of these die ontologies, mold component is carried out aspect the specialized vendor, will carry out the die ontology of additional processing and mold component installation and give the user, and cost-performance is good, and the manufacturing schedule also is favourable.

Here, die ontology has been carried out general description.This die ontology is considered as constituting the die cavity (blank part) of mold and the keeper of core rod (real core),, forms die cavity,, core rod is installed at active side (section) at fixation side (section).If with the die ontology closure, fixation side is contacted with two die joints of active side, then the space that is formed by die cavity and core rod constitutes the mold portion of moulded parts, to the resin of injecting fusion here.Behind temperature decline, resin solidification, then open die ontology, fixation side is separated with active side, take out the resin that solidifies, obtain moulded parts thus.

The structure image of die ontology is aforesaid to be constituted like that, promptly, the flat board of the steel of various polyliths is overlapped, by bolt they are connected, constitute fixation side and active side and other a plurality of sections, the parts of the guiding usefulness that is installed on each section are slided, it is led, even under the situation of active side relative fixed side shifting, deviation does not still appear in the mutual plane position of two sections.Therefore, die ontology is made of the part of the columnar bearing class of the columned post class of guide finger etc., pilot bushing etc. and bolt etc. in being referred to as the steel plate group of " plate ".

In addition, following mold component is assemblied in the die ontology as appurtenances, and this mold component has the various uses of demoulding pin (hollow shaft), locating ring, sprue bushing, fulcrum post, puller bolt etc.

Die ontology is made of smooth steel plate that is referred to as " plate " and the attached mold component that is referred to as " part ".

Must assemble the processing in the hole that above-mentioned part class uses to the plate class of above-mentioned grade.In addition, from the function aspects of die ontology, the installation screwed hole of the lifting bolt of the oilhole that cooling is used etc., water hole, bottoming hole, mould suspention usefulness etc. also is essential.They require to carry out the processing of various circular holes on the plate class that constitutes die ontology.

Also be useful on the irregularly-shaped hole beyond the circular hole that the core rod etc. of prebored hole of the inserting slot of die cavity installs, or the processing request of (the band end) pothole, but they are included in the processing in hole of wide meaning.

So the main body of the service that provides from the specialized vendor's side direction user who supplies with die ontology and mold component becomes the supply of carrying out die ontology, mold component, and the processing in hole that forms the plate class of this die ontology.That is, can consider to serve and roughly be divided into plate, part, this 3 class of (in plate, processing) hole.

Have again, in this manual, will be as the die ontology of assembly, constitute the steel plate of die ontology, (lead, pilot bushing etc.) guiding parts is attached to die ontology and the mold component installed is referred to as " mold component ".

In addition, also have following occasion, in this case, mold component (part) is adjusted, such as the lasting embedding of the total length of pin class, the additional processing that position of mounting hole change etc. are local.

Under the situation of Standard Module body, in the moment that the user orders goods, the specialized vendor can enter the standard processing in the 1st stage.

As a feature of this accessory system, the multistage ordering method is adopted in the processing of die ontology indication.That is, constitute in the following manner, this mode is: by in the design process of die ontology, order goods with a plurality of stages, in the design project progress, carry out the processing of die ontology.

Such as, dividing under the situation that 3 stages order goods, the order in the 1st stage (1 initial order) was carried out in the starting stage of following mould design, in the starting stage of this mould design, determined the appearance and size of die ontology, the size of the plate class of the template of mode structure etc.The stock's affirmation, arrangement, profile etc. that can carry out the plate class that constitutes die ontology and the critical piece that must use are processed with beginning.

Will be except die cavity, core rod periphery, from the order of the specification of the inserting slot of preceding half section template of determining to the interstage of mould design etc. as the 2nd stage (2 in the middle of order goods).

To arrange from the temperature adjustment hole of die cavity, core rod periphery and the order (3 final order) of the specification that second half section of the mould design of protrudent pin layout etc. is determined to terminal stage as the phase III.Thus, determine the whole specification of die ontology.

Order goods by carrying out the multistage like this, the processing of die ontology can be put into leading portion and carry out, realize shortening with the delivery date of Standard Module body that replenishes processing and Universal Die parts according to schedule easily.

In specialized vendor's side, can in every way this mould design aiding system be applied in many ways to evaluate, engineering design, the generation of NC data, delivery date are answered etc.

If use specialized vendor's side mold design aiding system 14, then by extracting and process necessary attribute with reference to shape symbol to processing, under not by artificial situation, evaluate operation, delivery answer etc., will specifically describe in the back about this point.In addition, also generate independent NC data easily.

Because the die shape shape of Standard Module body, mould composition etc. are clear and definite in the customer specification in the 1st stage, so proceed to appraisal, the processing (S21) of accepting and order for goods till this moment.At user side, answer (contact 15) by the network of internet etc. to appraisal, basic delivery date.

In this stage, processing hinders checks not too big necessity, generates (S23) through machining information, can begin die ontology processing (S24).

If according to processing specification indication (S6), the clear and definite design specification in the 2nd, the 3 stage is then carried out existing boring ratio and is hindered as the processing of the oilhole that replenishes processing, demoulding pin-and-hole and check (S22), if problem is arranged, then discusses with the user side designer.Identical with the 1st stage, generate (S23) through machining information, comprise whole processing (S24) of the additional processed mould body of height.

Under the situation of free size and structure mold body, the degree of processing specification indication (S6) is equivalent to the order of the 2nd stage from the aspect in period.Processing begins to have to be later than the Standard Module body.

In addition, in this mould design aiding system, owing to can at random add parts, the procedure of processing that newly is moved in the standarized component,,, momentarily issue to the user by the network of internet etc. therefore according to the shape of up-to-date shape symbol.

Do like this, easily program is carried out local interpolation and change, therefore help to enlarge the corresponding scope of processing of specialized vendor's side.Also has the advantage that to print mailing list again.

The die ontology of completion of processing is delivered goods to the user,, make assembling die cavity, core rod (S11A) at user side.Then,, adjust (S12), make mould (S13) through the fine finishining of mould.

Like this, the die ontology of payment has been finished the whole processing at design aspect appointment, and user side is by only making die cavity, core rod, and in die ontology the Manufactured die cavity of assembling, core rod and it is adjusted promptly can be made into mould.

The manner is for the service of the maximum that the user provides, and obtains design information constantly by in the middle of designing in manufacturer's side, will be according to short whole processed mould bodies and the mould parts of paying necessity of being finished by specialized vendor's side delivery date.

2. be primarily aimed at the explanation of the network in the specialized vendor

Below with reference to Fig. 2, the information transfering path of this die design accessory system is described.Fig. 2 is for putting down in writing the network of basic information transfering path based on the internal network of specialized vendor's side.

3. the internal structure of mold component design system of the present invention

Processing criterion control part and shape display part that this mold component design system is adopted are described.

Aspect software, the script of object oriented language Ruby (script) is core with the processing criterion control part that Ruby interface (windowsDLL form) constitutes by the processing criterion message control program (shape symbol) with the corresponding company of reference processing criterion data, added experience in the design aiding system of selling in the market in addition, the shape display part of windowsEXE form constitutes.

As hardware, adopt loader, the so-called personal computer of the display of CRT etc. with CPU, memory, keyboard, mouse etc.

As an example,, the processing criterion control part is described with reference to Fig. 3.Fig. 3 (a) is the block diagram of processing criterion control part and shape display part, and this figure (b) is the key diagram of the character of Ruby.In addition, the specific descriptions of this language are carried out separately.

Shown in Fig. 3 (a), the processing criterion control part is made of object oriented language Ruby, Ruby interface, processing criterion message control program, processing criterion data, shape display part interface etc.

The processing criterion control part is described by Ruby script (script), passing through the Ruby interface, with the coefficient while of object oriented language Ruby, according to the processing criterion message control program, provide internal information (the various attribute informations of size, tolerance, material etc.) based on the shape symbol of the said firm's processing criterion data.

The tabulation of the standarized component of putting down in writing in catalogue is arranged at the inside of this processing criterion control part fully.

The information of these parts is set at each parts as the attribute of shape symbol, shows in the shape display part, in this shows, can carry out necessary numerical value change etc.

The shape display part carries out the demonstration of 3D (as required, being 2D).The program that can almost use corresponding company shape that developed and that on market, sell to show same as before.

By the shape display part interface in the processing criterion control part, in the display of shape display part, the demonstration of processing criterion control part output is shown as image.

Ruby body, Ruby interface, shape display part interface etc. are the DLL form, can newly add program simply.

Here, DLL (Dynamic linking library; Dynamic link libraries) form can be according to the function that OS had of windows etc., and the routine (routine) of software is divided into several files, only with the file load of necessity in memory and use.

Particularly, the shape display part is by the interpolation of a spot of program, in the future, can show the output of processing criterion control part by the display part of the various CAD systems sold on the market.

In addition, die ontology is carried out various additional processing,,, realize the expansion of the additional and scope of this project usually according to user's hope.

Allowing the user generally understand newly to begin serve additional to add man-hour, if as before, rely on the catalogue of printing, the making again that then needs considerable fate and man-hour and replenish the mark of processing, the new issue approach that replenishes the printed articles such as printing of the explanation of processing also constitutes problem.

Only make the software that newly begins the additional processing of serving and, only issue this software to the user by Ruby script (script) and DLL form, and compare in the past, can issue in the quite short time on date from special network server by the internet.

The project of " the up-to-date module License Management of design system " of the function of the special network server of Fig. 2 is equivalent to this situation.

4. the explanation of the structure of shape symbol and attribute

In the service of specialized vendor at mould manufacturer, under the situation that is shaping dies, be used for the die ontology be the center and all finish according to the processing that the form that appurtenances are installed is carried out after, deliver goods, when being stamping die, be used for with the corresponding module of die ontology be the center and all finish according to the processing that the form that appurtenances are installed is carried out after deliver goods.

Below die ontology is described, if but die ontology is read to be module in addition, then also be common to stamping die.

Die ontology refers to carry out a plurality of rectangular steel plates overlapping and be formed in several sections that are fixed, the goods that wherein are respectively arranged with respectively the pilot bushing that slides, lead etc. and lead according to the indeclinable mode of the coordinate position on mutual plane.

In each significant points of this polylith steel plate, various mould parts (such as, demoulding pin, location distance piece etc.) are set, the hole that usefulness is installed is processed.In this hole processing, also comprise the processing in the hole of die cavity, core rod installation usefulness.

What the specialized vendor carried out, the service relevant with die ontology is divided into " plate " of the above-mentioned steel plate class of expression, from other " part " of mould parts of overall expression, is referred to as " hole " that be primarily aimed at the hole processing that steel plate carries out.

The shape symbol passes through Ruby script (script), the various attribute informations of the size of the component units (plate, part, hole) of description die ontology, tolerance, material etc.

In order to form the different shape symbol, symbolization Ruby script (script), it is used to keep constituting the various attribute informations of shape symbol; Dialogue Ruby script (script), it is used at the shape display part, the size of the each several part of demonstration conduct dialogue and attribute information etc., as required, the interface that provides the user to set value.

Dialogue Ruby script (script), symbol Ruby script (script) are shown in Fig. 3 (b), by the succession between several Ruby scripts (script) or with reference to constituting.Can existing each script (script) is overlapping successively, new system is made dialogue Ruby script (script) and symbol Ruby script (script), can make the new standard parts easily.

Like this, by according to existing program is added the not enough such form of function as parts and with stylish, obtain effective programming development environment.

The shape symbol is formed by " shape symbol attribute type " and " basic configuration type (pel) ".

Shape symbol attribute type is the structure of the various attribute informations of the size that keeps shape symbol each several part, tolerance, material etc., and it is maintained by the type structure that adopts the Ruby language.By type of process, can the action side between the data that be suitable for this shape symbol be controlled.That is, can limit the allowed band of certain data according to purposes shown in the type etc., or under certain condition, the processing that fixedly waits that is worth.

Each data type in the type is preserved with character string forms.

The shape symbol according to its character, mainly is divided into following 3 types with attribute type.

The 1st kind: by typonym, the unit (cell attribute (plate, part, hole), corresponding with the component names of catalogue.

The 2nd kind: be size (basic size, the high limit of tolerance, the low limit of tolerance), face (face) (processing mark, fine finishining precision, cylindricity mark), (crest line mark＜edge, edge, chamfering is inside and outside, fillet (fillet) inside and outside 〉, squareness, squareness datum length), material mark, heat-treatability etc., the physical attribute of its expression size, precision, material, heat treatment etc.

The 3rd kind: be initial point (configuration origin＜sx, sy, sz 〉, angle vector＜ax is set, ay, az 〉), arrange and (the pattern mark is set, datum plate is set, be provided with and arrive plate), scanning (passing marker＜translation scan, rotation sweep 〉, the angle of revolution, datum line＜beginning, finish), line (datum line＜beginning, finish 〉, straight line, circular arc＜centre coordinate, radius 〉), it is for belonging to the attribute of following described " basic configuration type " (pel), and it is the setting according to the pel in 3 dimension spaces, the appointment of coordinate position etc., the setting in hole and wire frame form the required attribute of pel.

In addition, size, outward appearance, edge etc. are also as the 3rd attribute of describing pel.

" type " by the 1st kind of classification changed processing, can control the action side of data and data (in the supervision of permissible value with under certain condition, the function that value is fixed etc.).

By the 2nd kind of classification, determine nearly all processing conditions.Particularly, also have by the processing mark of face and determine situation till using work mechanism.

Like this,, determine the 2nd classification, then abide by the processing criterion of corresponding company according to the disposing capacity of corresponding company if at each parts (all types of).Not only comprise size and precision, but also comprise wideer scope, until the material and the heat treatment of standarized component.

" basic configuration type " refer to the solid that is called as pel shown in Fig. 4 (a)～(e), and by this Fig. 4 (h), shown in (i) nemaline scanning obtained is shaped as basic configuration.

Pel is according to by these 5 kinds of solids such as cuboids, cylinder, the frustum of a cone, ball, hemisphere, and the mode of a kind of this pel or multiple combination of carrying out is represented basic configuration.

In each pel, determine the vector ve of the direction of presentation graphic initial point oa and pel.

With the cylinder shown in Fig. 4 (b) is example, is described with reference to this Fig. 4 (g), and this Fig. 4 (g) is by showing the key element of determining symbol shape and the particular content of representing this Fig. 4 (f) and each attribute thereof.

The center of the circle of bottom surface is figure initial point oa, on the axis of cylinder, according to arrow up, describes vector ve.

At pel is under the situation of cylinder, and its size can be described with height h1 by the diameter of a circle d1 of bottom surface.

Crest line is g1, two of g2, and face is 3 faces of f1～f3, must be described amounting to 5 attributes.

The typonym of the basic configuration type of cylinder is registered as " symbol cylinder ".Then, the setting of the cylinder on 3 dimension spaces is undertaken by following manner, and this mode is: as " coordinate, angle are set ", determine the coordinate of this figure initial point oa and the direction of vector ve.

For size, size 1, size 2 is by size d1, and size h1 defines.

The crest line attribute is according to the purposes of pel, selects chamfering (chamfer) (inboard C or circular arc), fillet (fillet) (C in the outside or circular arc overhanging).

The state of each face of face attribute representation.As aforesaid, the actual conditions of processing is also mainly by this face attribute description.

Like this, can not or being combined under the situation of line display with the monomer of 5 kinds of pels, as Fig. 4 (h), (i) shown in, adopt the shape that obtains by nemaline scanning.

Scan method comprises that revolution peacefully retouches these 2 kinds, and at first, on 2 dimensional planes, definition is by many line segments, or circular arc connect close-shaped.

Under the situation of rotation sweep, use following three-dimensional shape, this three-dimensional shape same plane on, determine reference axis, will be around this reference axis and closed shape obtains according to the mode of arbitrary angle rotary.Such as, if make wire shaped revolution 1 circle of Fig. 4 (h), then obtain the screw shape shown in Fig. 8 (a).

Under the situation of translation scan, adopt following three-dimensional shape, this three-dimensional shape forms close-shaped track when moving (being called translation) according to the mode perpendicular with being formed with close-shaped plane and with any distance.Such as, if distance according to the rules makes the wire shaped translation of figure (i), to handle owing to carry out shady line, some does not see, but obtains the hexagonal hole shape of the bolt that has shape hole, 6 limit shown in Fig. 6 (b).

As described above, shape by a kind in these 5 kinds of pels such as cuboid, cylinder, the frustum of a cone, ball, hemisphere or multiple combination, or nemaline rotation sweep, the shape that nemaline translation scan produces becomes the shape of " basic configuration type ".

In order to have the various technical information of the processing criterion that meets corresponding company, the component units of die main body (plate, part, hole) can by with the shape symbol definition for including the type of the shape shown in " basic configuration type " and " shape symbol attribute type ", from the shape symbol, information necessary such as appraisal, the information predetermined, processing usefulness of delivery date of extracting the specialized vendor generates, effective step management.

Inquiry process to die ontology is described, and the suitable example to the parts of monomer is described below.

In Fig. 5, from the mould parts catalogue of corresponding company, in flat demoulding pin, extract the part that is called (the total length appointment type that thickness of flange is 4mm).

Adopt the purpose of this pin to be to make the end face of moulded parts outstanding, so that make moulded parts molded in die cavity and core rod disengagement at elongated rectangular leading section (shown in A * B of figure (b)).

Fig. 5 (a) is the perspective view of the side of pin, and Fig. 5 (b) is positive perspective view, in Fig. 5 (c), and in the tabulation of standard component, by A, B, d, D, L, the combination of the numeral shown in the table of N will be with the parts of circle symbol as standarized component.

Such as, be A=1.0 at leading section, under the situation of B=5.0, if N=50, then total length L according to the unit correspondence of 0.01mm in 70.00～125.00 scope.Equally, be illustrated in N=60, under 70,80 the situation, can supply with according to the scope of the L in the table.

This catalogue the page or leaf content in, have in " the shape symbol attribute list " of shape symbol in description, record each several part size, dimensional tolerance, material (such as, SKS21), heat treatment (such as, to make hardness 59HRC ... SK21 is reached for the heat treatment step of the hardness of 59HRC and grasps as the processing criterion of corresponding company) etc. attribute formation group, it is stored in the native system.

In fact, when being shown in this pin in the display part, such as, the dialog box of hierarchy can be accessed successively, arrive the dialog box that shows flat demoulding pin (thickness of flange is the total length appointment type of 4mm).Select to have the suitably pin of (size) attribute from this dialog box easily.

The user also can at random design under the situation of the dialog box that does not access this pin.

If behind each parts in the design of having determined pin, in native system, inquire, then carry out the retrieval of flat demoulding pin, have under the situation of standard component at identical each parts, select this standard component.If there is not the standard component of identical each parts, then show each parts of similar standard component, if similar standard component is then selected in user's agreement.

For above-mentioned flat demoulding pin shown in Figure 5 (thickness of flange is the total length appointment type of 4mm), such as, when N=50, total length L can specify length arbitrarily in 70～125 scope.In this case, the selectable scope of total length L can be imported as the allowed band value of " as 70～125 scope of the processing criterion of corresponding company ".

On the other hand, though not shown in the drawings, under the situation of flat demoulding pin (flange is the type of 4mm), as an example, when leading section was A=1.0, B=5.0, total length L had 125,150,175,200 4 kinds permissible value, the user can select L from these 4 kinds.That is, can be from the tabulation of " processing criterion of corresponding company 4 kinds " permissible value, select total length L and it is imported.

Even for leading section is the same type of A=1.0, B=5.0, the price of total length appointment type increases.

Like this, selection or selectable scope from tabulate based on the permissible value of the said firm's processing criterion can be come it is imported as the allowed band value.

At random design the mould parts and in this system, inquire as user's mould designer, when the standarized component that has with the identical specification of attribute of these parts, represent that then it is a standard component.In addition, if there are not the parts of identical specification, the parts of retrieval of similar and it is shown that at the shape display part designer analyzes the similarity piece that has shown, if can use, then selects it, the processing of the dimension modifying of the parts of other of being correlated with etc. then.If can not use, then can form the operation of article made to order etc. according to initial design.

5. the instantiation of shape symbol (bolt and bolt hole)

In order to recognize the shape symbol and access to be carried out in data changes handled, in the display frame of shape display part, show dialog box as user's mould designer.The form of dialog box according to each shape symbol, adopts optimal display format.

As 1 example, with reference to Fig. 6～Fig. 8, on 3 block plates, offer various holes (spot-facing, through hole, female threaded hole), the bolt and these holes that have hole, hexagon angle are screwed togather, and 3 block plates are fastening, with this situation is example, and the actual operating position of shape symbol is specifically described.Each figure passes on left the dialog box image that sketch is illustrated in the screen displayed of display part, the right side with the shape glyph image as wire frame representation.

Fig. 6 (a) expression steel plate that mould adopted.Selection is determined size, material, heat treatment, Surface Finishing etc. as the plate of cell attribute.Pel is a cuboid, in the middle of the bottom surface of cuboid, has circular initial point oa.Usually, plate bottom surface and XY plane keeping parallelism, vector ve and Z axle keeping parallelism.

According to the demonstration of dialog box, specify the size of LWT.In this example, owing to adopt 3 block plates, therefore distinguish its corresponding input successively.

Usually, under the situation of the steel plate that constitutes die ontology, specify the structure and the size thereof of die ontology earlier, then, specify the purposes (the purposes name in die ontology) of each plate, then, input material, heat treatment, the fine finishining on surface etc.In the shape symbol,, its standard size etc. as the initial value input, in dialog box, is shown the various initial values as standarized component according to the board name of die ontology.In this occasion, can only import the numerical value that need change.

Fig. 6 (b) has the occasion of the bolt in hole, hexagon angle for definition.Cell attribute is a part, as pel, for the combination of cylinder, as hexagonal hole, adopts the shape of orthohexagonal wire shaped being carried out translation scan.Typonym is CSM.

Because the bolt that has a hole, hexagon angle is a standarized component, if the nominal of therefore specifying screw thread and head length is down then determined specification (catalogue) number, material, surface treatment etc.

Feature as native system, if length (stock of the said firm) is compared with standard component under the head of design arbitrarily, as has a standard component of same size, then select it, if there is not the standard component of identical size, then in table, list the standard component of length under the approximate head, could use and judge by the user.

Fig. 7 (a) is the situation of the shape in the hole of the steel plate of topmost having been carried out definition, forms the bolt hole that has the spot-facing of admitting bolt head.Cell attribute is the hole, and pel is with the form of 2 cylinder combinations, adopts HZAGURI.In the interior outside of plate, form chamfering (CHAMFEREX) as the expression at edge.Relative steel plate is determined the coordinate and the size that angle vector and each several part are set of initial point oa.Since porose, therefore figure initial point oa is arranged at the top along machine direction.

Because the steel plate that carries out spot-facing processing is specified, if therefore in dialog box, specify the internal diameter of spot-facing and the diameter of the portion of running through of the degree of depth and bolt body, determine uniquely that then one saves the length in the less hole of diameter.

Fig. 7 (b) is the situation of the shape in the hole of the steel plate in the middle of defining having been carried out definition, and this figure is according to only the mesopore that bolt body ran through being represented dialog box as the mode of straight hole (HSTRAIGHT).Cell attribute is the hole, and pel is about 1 cylinder, carries out C shape chamfer machining and the shape that forms.

Fig. 8 (a) is illustrated in undermost steel plate, as female threaded hole, gets through the thread Pilot hole in different holes, and screw thread is cut state to the way.Cell attribute is the hole, adopts the rotation sweep shape of wire shaped rotation 1 circle that makes Fig. 4 (h) as pel.Only form chamfering (CHAMFER EX) at end face.The shape designation is screwed hole (HTAP).

Must import the nominal diameter of screw thread, the effective length of screw thread, bottom outlet length.Bottom diameter is determined by nominal diameter usually, still, according to the processing criterion of corresponding company, goes back the effective length of double thread, and the material of steel plate, hardness etc. are investigated and carried out trickle adjustment.

As above-mentioned, the attribute of each parts is determined to be undertaken by carrying out following operation repeatedly, and this operation is: access necessary dialogue, by concrete numerical value etc., replace each position of initial demonstration.

If in Fig. 6 (a), (L, W T), then store this attribute to each parts of concrete size of input steel plate, show as the L with input, W, the plate of T in the display frame of 3D afterwards in dialogue.In addition, equally for the bolt that has hole, hexagon angle among this Fig. 6 (b), store its attribute by length under input nominal diameter and the head, and in the display frame of 3D afterwards, show according to the ratio of making.

In addition, after attribute informations such as size in the shape symbol that remains on these steel plates and mould parts are read processing, be shown in the picture image on the display of computer as 3 dimension shapes, operating by loader the computer of keyboard etc., under the situation of the change of the size of carrying out on 3 dimension spaces, position, arrangement angles etc., this change result is upgraded as the attribute information of size in the shape symbol etc.

That is, attribute information not only can be in dialogue, and can change in the display frame of 3D, and its result can be stored in the shape symbol.Therefore, even the attribute information of size etc. still can change in the display frame of 3D not showing seriatim under the situation of dialogue picture.

At 3 block plates, finished necessary hole respectively and specified, therefore shown in Fig. 8 (b), after the coincidence of 3 block plates, the axis in each hole is consistent, and inserting bolt.Show hole and bolt simultaneously, typonym is called HCSM.

Be that close the position of 3 block plates is certain relation, in order not destroy this position relation, by bolt they is connected under the situation of building block of die ontology at 3 block plates.

Also can in project, be set in to 1 property the corresponding hole of offering in 3 block plates as the XY coordinate of specifying bolt hole and the layout (graphic sign is set, datum plate is set, the arrival plate is set) of the attribute of the position of Z direction.

By simple example, the instantiation that the shape symbol is used is described above.Hole to 3 block plates is described, and provides concrete numerical value, determines as the size of the bolt that has hole, hexagon angle of mould parts and the Directory Number of standard component.

In the numerical value project relevant with the shape of " basic configuration type (pel) " with " shape symbol attribute type ", obtained above result, but, by understanding whole projects of " shape symbol attribute type " relevant with corresponding steel plate, the whole attributes that comprise hole processing of clear and definite 3 blocks of plates.

Therefore, can comprise that cell attribute is the original arrangement of 3 block plates of plate and the shape processing of hole processing.Cell attribute be the bolt of band hexagonal hole of part as standarized component, can realize the manufactured goods arrangement.

Actual mould is designed to require very long-standing operation, constitutes near concluding time of design that time that the design of 1 steel plate of die ontology finishes fully is in die cavity, core rod.

But, if select early stage to determine the hole coordinate of lead, pilot bushing etc., then, determine the setting of die cavity at die ontology, then carry out the design of runner gate relation.The design that influences the design in hole of demoulding pin etc. of shape of products of manufacturing and die cavity, core rod is placed at last in the lump to be carried out.

Therefore, if carry out the mould design and provide acquired data, then can carry out multistage order by the data of design performance according to the mode of suitably separating by this die design accessory system.

In design during as unit (unit) structure of the die ontology of the combination of a plurality of shape symbols etc., each the shape symbol in this system acting is kept at by Ruby to be provided, and is called in the memory cell of hash.

For the shape symbolic information being converted to appraisal information and machining information form, then from said memory cells, access necessary information selectively, use this information.

Fig. 9 below with reference to drawing as image is described the method that accesses that is stored in the information in the hash.

Be kept at the shape symbol in the hash, shown in Fig. 9 (1), continuous access to whole shape symbols is handled, and specifies the access processing etc. of specific shape symbol and can freely obtain the shape symbolic information by the associative sets number of hash shown in Fig. 9 (2).

So, the attribute information of shape symbol is carried out the access processing, the purposes (plate, part, hole) of shape symbol is judged acquisition appraisal, machining information generate necessary computational element.Computational element refers to purposes, configuration initial point, size, material (occasion of plate, part), processing method (occasion in hole) etc.

In shape symbol purposes is under the situation of plate, part etc., according to the information that obtains as the aforementioned calculation purposes, designation as the supposition component names that becomes keyword (key), is generated the supposition component names according to the said firm's explicit representation.Can suppose component names according to this, generate the appraisal information that meets the pro forma invoice form.

In shape symbol purposes is under the situation in hole, obtains to constitute the plate information of processing object.Be provided with constantly at the shape symbol, it is stored in the attribute information.

Then, at every block of plate, generate formation and meet the machining information of the machining information of the said firm's display packing with form.

Can in by all departments of the organic link of aforesaid specialized vendor LAN, use same as before by above-mentioned appraisal information, machining information.

6. general CAD system is related with the mold component method for designing

The DLL form is adopted at Ruby main body, Ruby interface, shape display part interface, can add new procedures simply, and it is used with existing program, and this point is described.

If the process that will utilize the shape symbolic information of controlling according to the processing criterion of corresponding company as such as, the personal computer of the market sale of Windows etc. is disclosed with the interface of the DLL of OS, then in the CAD system that can on using market, sell, momentarily utilize the attribute information of shape symbol.

In the future, can in the display of the display part of the CAD system of market sale, show dialog box etc. and can use the attribute information of the shape symbol of this mold component design system at once.

If like this, then user's mould designer needn't watch other display part in the CAD system that uses our company, can be with reference to the standarized component that also adopts the processing criterion that meets corresponding company.

Like this, by in the shape symbol of Ruby system, record is as the processing criterion of the corresponding company of initial value, can obtain with reference to the identical effect of the printed catalogue of the said firm.Because the designer can obtain the attribute information of corresponding company processing criterion in the CAD system that uses our company, therefore break away from the trouble of browsing catalogue.In addition, if there is not fatal especially problem, then can select to meet plate, part, the hole processing of corresponding company processing criterion.

As mentioned above, because the inside of shape symbol used in the present invention comprises the various technical information as its attribute,, then all access each the shape symbol that belongs to these parts if therefore specify certain specific mould parts, can from this attribute information, obtain concrete technical information.

Therefore, in the order pattern of present catalogue, use the name of product mark, but, those that in this unique character string, represent comprise the name of product mark of enumerating with literal that replenishes the processing indication can be fully attribute by the shape symbol show, realize not entrusting the processing indication of name of product mark.

That is, have following advantage, that is, user's mould designer needn't stick to towards the name of product mark of the order special use of the said firm, in the scope of the processing criterion that the said firm provided, can carry out the higher specification indication of the free degree.
