Each pad the 81, the 82nd is that base material 81a, the 82a of rectangular plate shape forms by integral body, in the face of the surface coverage of die main body 63 sides has very thin uniform inorganic material film 93.Here, inorganic material film 93 is established for the thickness of critically adjusting pad 81,82, and detailed content is narrated subsequently.And tabular base material 81a, 82a has abutting part 81b, 82b and main part 81c, 82c, and described abutting part 81b, 82b are overshooting shape, and described main part 81c, 82c support abutting part 81b, 82b from behind.Under the state that pad 81,82 is assembled as shown in Figure 2, surperficial S31, the S32 of abutting part 81b, the 82b of one side side fit tightly in template 61 sides, and surperficial S33, the S34 of the inorganic material film 93 of main body covered part 81c, the 82c of another side fits tightly in die main body 63 sides.Here, the rectangular box-like surperficial 85c that exposes around base material 81a, the 82a forms, specific surface S31, S32 are that surperficial S33, S34 side are stepped back and be lower than surperficial S31, S32 to dorsal part more, shown in Figure 17 (A), abutting part 81b, 82b overlook the size little circle of size than main part 81c, 82c.
As shown in Figure 2, when die main body 63 is fixed in template 61, the side S11 of die main body 63 and the inner surface P21 of template 61 are vertical with the AB direction and parallel with CD, EF direction via pad 81, and the side S12 of die main body 63 and the inner surface P22 of template 61 are vertical with the CD direction and parallel with AB, EF direction via pad 82.And then, can change pad 81,82 by unclamping bolt B O, owing to prepare the pad 81,82 of multiple different-thickness in advance, simultaneously, thickness by increase and decrease pad 81,82 changes to suitable thickness, the position of die main body 63 relative templates 61 can be adjusted, the accent core of the die main body 63 relative dynamic models 42 of cover half 41 sides can be realized.In addition, the thickness of pad 81,82 representative from surperficial S33, the S34 of main part 81c, 82c to the surperficial S31 of abutting part 81b, 82b, the distance of S32.Prepare pad kit in advance, it is a plurality of pads about a few tenths of μ m～a few tenths of ten μ m that its set has thickness difference for example, from this pad kit, select to be fit to the pad 81,82 of die main body 63 and to replace, can regulate the thickness of pad thus freely.Owing to can fine change the thickness of the pad 81,82 that constitutes aforesaid pad kit, can improve and transfer the core precision.Can on each pad 81,82, engrave the mark or the numerical value of its thickness of expression in advance.Like this, since the location that can utilize pad 81,82 to realize die main body 63, the accent core in the time of can reliably and accurately changing die main body 63.And, when owing to long-time use die main body 63 and need transfer core again the time, also can be simple and easy and carry out the such core of accent again operation reliably.
Figure 18 is the figure of the manufacture method of explanation pad 81 shown in Figure 17.At first, shown in Figure 18 (A), prepare plate member 92 as the blank (unit) of pad 81.This plate 92 is thickness flat boards greater than the target thickness of slab.This plate 92 is to be formed by stainless steel (for example SUS420), carbon steel (for example S45C), superhard alloy etc.Wherein, carbon steel is softer and be processed into target shape easily.And carbide alloy hardness is high and be difficult for processing, but can critically control thickness through cutting progressively.As Figure 18 (B) shown in, by the machining that comprises cutting, grind, remove the superficial layer 92a of plate 92 and form as the processing of base material 81a dull and stereotyped 92b thereafter.This is processed dull and stereotyped 92b and has high surperficial 92c of flatness and back side 92d, and its thickness t p is thinner slightly than final goal thickness, allows the error of prescribed limit.Here, can finish the processing of the dull and stereotyped 92b of processing by cutting at one time and leveling operation, but usually, preferred limit monitors the thickness t p of the dull and stereotyped 92b of processing, repeatedly cut and the leveling operation on the limit.Use contact, all thickness sensor such as contactless to measure the thickness t p of the dull and stereotyped 92b of processing.In addition, processing can be processed the abutting part 81b of overshooting shape during the 92d of the back side together, and like this, back side 92d becomes the surperficial S31 with the inner surface P21 butt of template 61.Then, shown in Figure 18 (C), by forming inorganic material film 93, the surface 33 of the side S11 butt of formation and die main body 63 on the surperficial 92c of the dull and stereotyped 92b of processing.Thus, can access the pad 81 that is coated with inorganic material film 93 in the one side of base material 81a.This pad 81 has following structure: the first face portion 81u, and it is disposed at an interarea side (upside of drawing) of pad 81 and has inorganic material film 93; The second face portion 81s, it is disposed at another interarea side (downside of drawing) of pad 81 and has abutting part 81b; Mid portion 81t, it is sandwiched between the first face portion 81u and the second face portion 81s.As the filmogen of the inorganic material film 93 that is used to form the first face portion 81u, can use for example metal, metallic compound, carbon film etc.As the metal filmogen, can use titanium, chromium etc., to use under the situation of chromium, the hardness, particularly plate member 92 that can improve inorganic material film 93 are under the stainless situation, thermal coefficient of expansion is close, prevents that the effect that inorganic material film 93 comes off from improving.In addition, as the metallic compound filmogen, can use for example titanium nitride etc.And as the carbon element film of filmogen, diamond-like-carbon (ダ ィ ャ モ Application De ラ ィ Network カ one ボ Application) specifically is because the hardness height of diamond-like-carbon is easy to keep dimensional accuracy, not the advantage of easy damaged.Above film forming can be undertaken by PVD such as vacuum evaporation, sputter (physical vapour deposition (PVD)) method, also can be undertaken by CVD (chemical vapour deposition (CVD)) method.Through after the above film formation process, the thickness summation tf that processes dull and stereotyped 92b and inorganic material film 93 equals final goal thickness, and in the desired error allowed band of pad 81 finished products.That is, the thickness of inorganic material film 93 equals the value that final goal thickness t f deducts the thickness t p gained of measuring before the film forming.In addition, for example by the PVD method, when the CVD method is carried out film forming, come the thickness of inorganic material film 93 is controlled by adjusting film formation time.And,, also can adjust the thickness of inorganic material film 93 by changing the film forming amount in the unit interval.
In addition, for the material of the base material 81a of pad 81,82, be not only to consider that the machining difficulty gets final product, also need to consider and die main body 63 matchings (phasic property).For example, the thermal coefficient of expansion of the thermal coefficient of expansion of preferred substrates 81a and die main body 63 is close, thereby, can suppress the different and dislocation that causes of thermal expansion.And, more than be the manufacture method of a pad 81, another pad 82 also can use the same method and make.
Figure 19 is the diagrammatic sketch that illustrates by the manufacture method of a plurality of pad kit that pad constituted with a series of thickness from conceptive.Figure 19 (A) is the diagrammatic sketch that the manufacture method of the thinnest shim pack (a group 5) is described.At this moment, the plate 92 of Figure 19 (A) is cut and obtain processing dull and stereotyped 92b, its thickness is between lower thickness T1a and upper thickness T1b.At this moment, the value Δ is as the tolerance of the thickness of machining and be set, though comparatively loose to the required precision of thickness, the required precision of flatness is not loosened.Process the final thickness of dull and stereotyped 92b and promptly process thickness T 10, be equivalent to the thickness t p shown in Figure 18 (B).In operation thereafter, on the dull and stereotyped 92b of processing, form for example inorganic material film 93 of thickness T11.The result is, the thickness of pad 81 (the thickness t f that is equivalent to Figure 18 (C)) is T10+T11, and this value is as the minimum of a value of described shim pack and be set at first.Thickness T12, the T13, T14, the T15 that are set in the inorganic material film 93 in the same shim pack are set as 4 grades, and every grade increase is 0.5 μ m for example.The result is, the thickness of pad 81 becomes 5 grades, promptly, T10+T11, T10+T12, T10+T13, T10+T14, T10+T15, for example, if minimum of a value (T10+T11)=3mm then can be that 5 pads of 3.0000mm, 3.0005mm, 3.0010mm, 3.0015mm, 3.0020mm are supporting with thickness.
In addition, in the above description,, but it is not waited, at this moment, set each thickness T12, T13, T14, T15 respectively with the deviation between the part of compensation processing thickness T 10 for the processing thickness T 10 that simply makes the dull and stereotyped 92b of processing equates.
Figure 19 (B) is the figure of the manufacture method of the thicker shim pack of next group thickness of explanation.At this moment, carry out machining and obtain processing dull and stereotyped 92b, its thickness is between lower thickness T2a and upper thickness T2b.The final thickness of processing dull and stereotyped 92b is promptly processed thickness T 20 and is equivalent to the thickness t p shown in Figure 18 (B).On 5 dull and stereotyped 92b of processing, form the inorganic material film 93 that thickness is T21, T22, T23, T24, T25 individually respectively.The result is, the thickness of pad 81 that is equivalent to the thickness t f of Figure 18 (C) is set as 5 grades of T20+T21, T20+T22, T20+T23, T20+T24, T20+T25, and every grade increases by 0.5 μ m.The result is, the concrete thickness of 5 supporting pads 81 is, for example, and 3.0050mm, 3.0055mm, 3.0060mm, 3.0065mm, 3.0070mm.More than, for the processing thickness T 20 that simply makes the dull and stereotyped 92b of processing all equates, but it is not waited, at this moment, set each thickness T21, T22, T23, T24, T25 respectively with deviation between the part of compensation processing thickness T 20.
Figure 19 (C) is the figure of the manufacture method of the thicker shim pack of next group thickness of explanation.At this moment, carry out machining and obtain processing dull and stereotyped 92b, its thickness is between lower thickness T3a and upper thickness T3b.The final thickness of processing dull and stereotyped 92b is promptly processed thickness T 30 and is equivalent to the thickness t p shown in Figure 18 (B).On 5 dull and stereotyped 92b of processing, form the inorganic material film 93 that thickness is T31, T32, T33, T34, T35 respectively.The result is, the thickness of pad 81 that is equivalent to the thickness t f of Figure 18 (C) is set as 5 grades of T30+T31, T30+T32, T30+T33, T30+T34, T30+T35, and every grade increases by 0.5 μ m.The result is, the concrete thickness of 5 supporting pads 81 is, for example, and 3.0100mm, 3.0105mm, 3.0110mm, 3.0115mm, 3.0120mm.More than, for the processing thickness T 30 that simply makes the dull and stereotyped 92b of processing all equates, but it is not waited, at this moment, set each thickness T31, T32, T33, T34, T35 respectively with deviation between the parts of compensation processing thickness T 30.
Though below omit, in order to last method a plurality of shim pack are laid in as pad kit, can access the very wide thickness of scope, can utilize pad 81,82 very critically die main body 63 to be positioned.In addition, there is no need indivedual each pad 81,82 that constitutes above each shim pack of making, for example can form simultaneously that thickness equates or approaching a plurality of inorganic material films 93, at this moment, utilize mask etc. can carry out the fine setting of film formation time alternately.And the thickness of inorganic material film 93 is not limited to 5 grades, can be made as various grades.But in the practical application, the thickness of inorganic material film 93 preferably sets more than 0.1 μ m in the scope below the 2.0 μ m.
