Physical vapor deposition of sputter and ion plating etc. (PVD) or chemical vapor deposition method are used in the film forming of bottom 42, protective membrane 43 and following intermediate coat.
Fig. 6 is the structure sketch map that forms the sputter equipment of bottom 42 and protective membrane 43 continuously.
As shown in this figure, 51 central part is provided with worktable 52 in the chamber, and a plurality of brace tables 53 are installed on the worktable 52.Fig. 7 illustrates the expansion stereographic map that brace table 53 upper supports the state of member 65.The central part of brace table 53 is erect pillar 66 is being set as shown in this figure, and top board is being fixed at the top of pillar 66, is hanging the member 65 that a plurality of for example entry needles 5 (with reference to Fig. 1) wait the Coinjection molding apparatus of formation around top board 67.With Fig. 7 is example, and entry needle 5 is hung on the top board 67 than elongate members 65 like that, if when member 65 is bigger, just is installed on the brace table 53 singly.Worktable 52 and brace table 53 are at the uniform velocity rotated along the direction of regulation by the effect of electric motor and its power transmission parts (not completely shown among the figure), and the member 65 that brace table 53 supports also rotates with the rotation of brace table 53.
Load tabular bottom with the sputter vapor deposition source 56 that target 54 and protective membrane use with target 55 along the periphery of worktable 52, be provided with the identical distance of cardinal principle respectively.In the present embodiment, the thickness of bottom 42 is thinner than protective membrane 43, so bottom is installed 1 with target 54, protective membrane is installed 3 with target 55.When bottom was 2 layers, for example the 1st bottom had 1 with target, and the 2nd bottom has 1 with target, and protective membrane is just installed 2 with target 55.Bottom is made of the metal sheet of selecting at least a element to make principal constituent from Cr, W, Ti, Si group with target 54, and protective membrane is made of graphite cake with target 55.
In addition, in chamber 51, be provided with gas pipeline 62, answer vacuum tightness in the holding chamber 51 10
0～10
-1Pa, discharge is selected argon (Ar) gas with rare gas element, and fluoro-gas selects tetrafluoro-methane (CF
4), hexafluoroethane (C
2F
6) etc.The shielding power supply (not shown) adds sputter electric power as the certain hour in following on sputter vapor deposition source 56.Owing to add this sputter electric power, the plasma zone 64 of argon all forms while bottom 42 and protective membrane 43 also can continuous film forming.
Fig. 8 is the outer explanatory view that is added on the state of sputter electric power on the target 54,55.As shown in this figure, article one is to add the voltage of 500W in the state of bottom with (solid line) on the target 54, and second is the state (dotted line) of closing (0W) for being added on protective membrane outward with the voltage on the target 55.This sputter electric power that adds has produced plasma zone, and argon ion rushes at bottom and ejects the target material with target 54, and the particle of its sputter is piled up on the body material 41 of member 65 and formed bottom 42.Member 65 spins are repeatedly by the front of bottom with target 54, thereby the bottom 42 of formation complete and homogeneous.Be stacked at bottom 42 before the thickness of about regulation, sputter electric power is kept constant.
Gradually weaken the sputter electric power on the bottom usefulness target 54 then; gradually strengthen simultaneously the sputter electric power on the protective membrane usefulness target 55; when protective membrane reached 1000W with the electric power on the target, bottom was 0W with the electric power on the target 54, kept this state certain hour afterwards.
So, on bottom 42, pile up formation DLC film because of the carbon particles that the impact of argon ion is ejected, in the carbon particles banking process, fluorine is sneaked into wherein together because of being mixed with fluoro-gas in the Ar gas, form the protective membrane 43 that fluorine-containing DLC constitutes.At this moment, repeatedly use the front of target 54, thereby form the protective membrane 43 of complete and homogeneous by bottom with the spin of member 65.
Switch to when forming protective membrane 43 by forming bottom 42, as mentioned above, weaken bottom gradually with the sputter electric power on the target 54, strengthen protective membrane simultaneously gradually with the sputter electric power on the target 55.Thus; the composition generation continuity of bottom 42 and protective membrane 43 changes and presents concentration gradient; the percentage composition that body material 41 sides of bottom 42 constitute its metal is approximately 100%; along with the percentage composition to protective membrane 43 side shifting metals reduces gradually; the percentage composition of fluorine-containing DLC increases; middle portion at bottom 42 and protective membrane 43; the percentage composition of metal ingredient and fluorine-containing DLC approximately respectively accounts for half; the percentage composition of metal ingredient is littler when protective membrane 43 sides, is approximately 100% near the percentage composition of fluorine-containing DLC on the surface of protective membrane 43.Therefore, the boundary of bottom 42 and protective membrane 43 is difficult to clearly to divide (so being shown in broken lines around the boundary of bottom 42 and protective membrane 43 among Fig. 5).
The thickness of bottom 42 is 0.1 μ m～2 μ m; preferred 0.1 μ m～1 μ m; the thickness of protective membrane 43 is 0.1 μ m～5 μ m, and preferred 0.5 μ m～3 μ m is if select thin film for use; be difficult to form good separability and flowability; on the other hand, if film is blocked up, protective membrane 43 will own strip down from body material 41 sides easily; diminish its function, so the thickness of preferred above-mentioned scope.
For example, member 65 has the occasion of hole, recess, protuberance etc., if adopt the collimation sputtering method that is provided with trellis collimating instrument electrode between member 65 and the target 54,55, preferably optionally adhere on it with the vertical sputtering particle of face of the hole of member 65, recess, protuberance.
Fig. 9 is the explanatory view to the principle of the uneven magnetron sputtering system of suitable formation above-mentioned bottom 42, protective membrane 43 and intermediate coat described later.
As shown in the figure; be provided with the inboard magnetic pole 56 that can form low-intensity magnetic field with target 54 and protective membrane with the relative position of about central part of target 55 at bottom; the relative position of periphery at target 54,55 is provided with the outside magnetic pole 57 that can form high-intensity magnetic field, thereby forms unbalanced magnetic field.
And, when forming plasma zone 64, have the part of the magnetic line of force 58 that powerful outside magnetic pole 57 produces to reach near the member 65.The plasma (for example argon ion) that produces during along these magnetic line of force 58 sputters is compared with common sputter with electronics, has more arrival member 65 surfaces, therefore forms bottom 42, protective membrane 43, the intermediate coat of surface smoothing densely.
Figure 10 illustrates the part that forms the state of protective membrane on the relevant body material of variation of the present invention to enlarge sectional view.Shown in this figure, form on the body material 41 that the steel of SKD etc. constitute, form it on carbon and hydrogen intermediate coat as the DLC formation of principal constituent with the bottom 42 of Cr as principal constituent
Because; gradually weaken bottom with the sputter electric power on the target; gradually strengthen simultaneously and be the sputter electric power on the graphite cake (intermediate coat protective membrane target) that forms the DLC film; for this reason, form the mixing field layer 45 of concentration gradient around the boundary of 44 of bottom 42 and intermediate coats with Cr and DLC.And, in the forming process of intermediate coat 44, supply with fluoro-gas, so that on intermediate coat 44, form the protective membrane 43 that fluorine-containing DLC constitutes.
The thickness of present embodiment is respectively bottom 42 about 0.1 μ m, mixing field layer 45 about 0.2 μ m, intermediate coat 44 about 0.7 μ m, protective membrane 43 about 0.5 μ m.Do not form intermediate coat 44 and directly form the protective membrane 43 that fluorine-containing DLC constitutes on bottom 42, or below protective membrane 43 during formation intermediate coat 44, whole film became soft when intermediate coat 44 was thinner than protective membrane 43.
Therefore as present embodiment, form intermediate coat between bottom 42 and protective membrane 43, and the thickness of intermediate coat 44 is when thick than the thickness of protective membrane 43, intermediate coat 44 has the effect of enhancing protective membrane 43, and can make protective membrane become the very strong film of wearing quality.
In the Coinjection molding apparatus shown in Figure 4,, be necessary to form from the teeth outwards protective membrane 43 as shown in figure 10 in order to make molding resin stream on inner chamber 36 facing surfaces of fixed mould 33.
On the other hand, the surface of moveable die 34 is covered by pressuring template 32 and does not contact with molding resin, and forms the structure that contacts with pressuring template 32.So the surface of moveable die 34 as shown in figure 11, on body material 41, form bottom 42, mixing field layer 45, intermediate coat 44 and do not form protective membrane 43.It has good wearability and low frictional properties owing to there is the intermediate coat 44 that DLC constitutes on the surface of body material 41, thus can prevent relative moveable dies 34 slips of pressuring template 32 time to its wearing and tearing.Preferably also form the protective membrane 43 that fluorine-containing DLC constitutes on the surface of the pressuring template 32 that contacts with molding resin in this case.
The protective membrane 43 that can exist fluorine-containing DLC to constitute on the outside surface of moveable die 34, the physical strength of comparing intermediate coat 44 with protective membrane 43 is big, so the outside surface of preferred moveable die 34 scribbles intermediate coat 44.
The expansion orthographic plan of the state of mouth-sealed portion during Figure 12 and Figure 13 ABS resin center that to be expression form with the shaped device of Fig. 1.Figure 12 forms the bottom 42 that W constitutes on the body material 41 that SKD constitutes as shown in Figure 5; the expansion orthographic plan that adopts the entry needle 5 (with reference to Fig. 1) of all coating the protective membrane 43 that fluorine-containing DLC constitutes on the bottom 42 to seal, Figure 13 are not to be coated with the expansion orthographic plan that the existing entry needle of protective membrane 43 seals on the surface of adopting SKD to constitute.
When using existing entry needle, bad with the separability of resin, so, the thrust of air bubble-shaped appears in the closure part of moulding product as shown in figure 13, produce burr, and cause the cast gate position significantly concavo-convex, outward appearance is not good.
On the contrary; because when adopting the entry needle of the protective membrane 43 that the fluorine-containing DLC of coating constitutes and the separability of resin good; so the air bubble-shaped thrust of the closure part of moulding product be can't see substantially as shown in figure 12; form the roughly neat cast gate position of equatorial, have very big-difference in appearance with existing cast gate position as shown in figure 13.
Entry needle particularly in the member of Coinjection molding apparatus; and the gap between nozzle body is little; when the force feed molten resin, need quite high pressure; cause the resin temperature height; after finishing, moulding have residual resin to adhere on it; owing to entry needle guide pin bushing 6 (with reference to Fig. 1) slip is arranged, so scribble the protective membrane of fluorine-containing diamond-type carbon on the surface of entry needle, the sliding with above-mentioned entry needle guide pin bushing 6 strengthens so in addition.
Figure 14 and Figure 15 are the explanatory views of the method for stripping test.As shown in figure 14, on the surface of the test film 71 that the SUS of mirror finish (HPM38) constitutes, scribble various DLC films 72, in the aluminum pipe of internal diameter 3mm, fill various toners.Like this, the lower ending opening position of aluminum pipe 73 is connected with above-mentioned DLC film 72 and is erected on the test film 71, is heated to 250 ℃ by electric furnace aluminum pipe 73 is adhered on the test film 71.
Secondly, as shown in figure 14 aluminum pipe 73 is horizontal positioned, test film 71 is positioned on the base station 74, and the push part 76 of push-pull type meter 75 at the uniform velocity descends with the speed of 25mm/min, applies shear-stress on aluminum pipe 73.And estimate stripping strength with the pushing intensity of aluminum pipe 73 when test film 71 is peeled off.Hits in each test is 5.
Figure 16 and Figure 17 are peeling strength test result's synoptic diagram.Figure 16, Figure 17 are respectively ABS resin, polystyrene resin is filled in the synoptic diagram in the above-mentioned aluminum pipe 73.In addition, among each figure on the X finger to finger test sheet 71 uncoated any material directly by the resin aluminum pipe of on the SUS minute surface, adhering, coating DLC film on the Y finger to finger test sheet 71, the test-results of coating fluorine-containing DLC film of the present invention on the Z finger to finger test sheet 71.
Obvious by figure, the stripping strength of comparing use with other (X, Y) that scribbles fluorine-containing DLC film of the present invention (Z) is low, and promptly the separability to resin is good, and the standard deviation of stripping strength is also littler than other.
Figure 18 is the orthographic plan of the moveable die that uses in the resin flow test in the mould.Shown in this figure, test forms spiral goove 82 with the surface of moveable die 81 as oblique line illustrates, and the degree of depth of spiral goove 82 is 10mm for the 0.5mm width.Have 12 ejector pins 83,84 in the way of spiral goove 82 alternately.
On the other hand, test is not with forming spiral goove 82 on the fixed mould, and the surface of the spiral goove 82 of corresponding above-mentioned moveable die 81 is level and smooth.Above-mentioned ejector pin 83 corresponding positions in the centre of this fixed mould are provided with the resin filling orifice, just can enter spiral goove 82 by this filling orifice resin.
This test is joined with moveable die and fixed mould face face and is carried out matched moulds, under the condition of 320 ℃ of mold temperatures, injection speed 200mm/s, injection pressure 200Mpa, polycarbonate (R1700) is injected from resin filling orifice 83, at this moment, resin flow to from spiral 82 by spiral 82 middle bodies actually where test, it the results are shown in Figure 19.
Among Figure 19, transverse axis is meant that mobile length is as amount of flow in mould with resin, and the longitudinal axis is meant frequency (individual).White among the figure straight rod figure expression moveable die and fixed mould have only carried out the SUS spare (HPM38) of mirror finish, and the straight excellent figure of black is illustrated on the SUS spare (HPM38) that moveable die and fixed mould carried out mirror finish and has also formed fluorine-containing DLC protective membrane of the present invention.In addition, the injection volume that illustrates each mould is 25 o'clock its frequency distribution.
Scheme obviously thus, die surface forms the present invention of fluorine-containing DLC protective membrane, even the degree of depth of spiral goove 82 when to be 0.5mm extremely shallow, not only the resin flow in the mould is splendid, and adapts to very much shaping thin wall.
Constitute in the parts of Coinjection molding apparatus forming mould particularly because the injection resin flow is good and good and have a following advantage with the demoulding of molding resin.
Zero can use the big molding resin of molecular weight, can improve the mechanical property of moulding product
Zero can reduce mold temperature, weakens heating electric power
Zero does not need demoulding awl on forming mould, or tapering can diminish
Zero reduces the ejector pin number
Zero shortens intermittently (shaping cycle time)
Zero can realize shaping thin wall
Zero can carry out the moulding of complicated shape
Zero improves the erosion resistance of forming mould
But the choice of zero condition of molding increases, and shaping cycle is stable
Be difficult for the band flaw on zero forming mould, easily handle mould
Zero existing forming mould is it to be had with the release property of molding resin have to reduce the die surface roughness, even mould die surface roughness height of the present invention also can be done mirror finish to die surface
So the nonvoluntary external force that applies during zero injection-molded article is the metamorphism of rare bending etc.
When being vinyl chloride resin, shaping resin material easily produces chlorine, easily produce halogenide and phosphides such as chlorine and oxygen during for nonflammable resin, easily contain vulcanizing agent during for ABS resin, formic acid and formalin are easily arranged during for polyacetal resin, easily produce corrosive gasess such as ammonia and carbon monoxide during for low foamed resin.
But the protective membrane that fluorine-containing DLC of the present invention constitutes has the advantage of erosion resistance, so the member of shaped device can prevent to be corroded by above-mentioned corrosive gases, and prolongs work-ing life of shaped device, more easily keeps stable shaping cycle.
The present invention has formed above-mentioned structure, has been coated with the protective membrane that fluorine-containing DLC constitutes with the contact surface of resin, improves the empyreumatic phenomenon disappearance of the projection of the air bubble-shaped that the surface of moulding product produces, flash, the demoulding etc. and resin with the separability of resin.Also have, resin flow is good, thereby has improved processability, can realize shaping thin wall and precise forming.
In addition, the protective membrane that fluorine-containing DLC constitutes has the advantage of erosion resistance, and the corrosive gases that produces when just having eliminated moulding etc. prolongs the work-ing life of shaped device to the corrosion of member, more easily keeps stable shaping cycle.
