In the case, as Fig. 6, shown in Figure 7, form and to make in each inner cavity surface of inner chamber 102a on the inner cavity surface (the inner cavity surface 102d among Fig. 6, Fig. 7) that the end face 21c (with reference to Fig. 1, Fig. 2) with inside surface 21a (the described applying scope E1) adjacency of the panel part 21 of main part 1a is shaped, be provided with in inner chamber 102a and inject the cast gate 102c that uses by the flow state resin from injection molding machine 104 of running channel 102b force feed.Particularly, cast gate 102c is formed on inner cavity surface (the inner cavity surface 102e of the two figure) side that the outside surface 21b that makes panel part 21 that is arranged in film for internal mould 131 positions of living in that removing of inner cavity surface 102d sandwich by main part 113 and main part 123 is shaped, and be formed at width W 2 (the promptly identical width of the film for internal mould 131 of length direction (above-below direction among Fig. 4) along inner cavity surface 102d with the width W 1 of described applying scope E1, with reference to Fig. 4 and Fig. 8) interior position (as an example, the central portion of width W 2).Therefore, as shown in Figure 7,, film for internal mould 131 is pressed into the inner cavity surface 102f relative with inner cavity surface 102e (inner cavity surface that the inside surface 21a of panel part 21 is shaped) side by the pressure of the resin that injects in from cast gate 102c toward inner chamber 102a.
As shown in Figure 5, the ingredient of mobile side metal pattern 121 comprises basal part 122, main part 123, cushion block 124 and jet tray 125.Basal part 122 formation are tabular, and constitute the mobile side installation portion (not shown) that can be installed in injection molding machine 104.Main part 123 is fixed on basal part 122 by cushion block 124, forms inner chamber 102a with the main part 113 of fixation side metal pattern 111.In the case, main part 123 as shown in Figure 6, (in other words the position (being described applying scope E1 (with reference to Fig. 2)) of applying nesa coating 3 of the inside surface 21a of panel part 21 is shaped, push film for internal mould 131 during the mould internal shaping) inner cavity surface 102f two ends (end of above-below direction among Fig. 6) and with metal die face (for example interphase) 123a of these two end abutment between do not have height difference and be connected continuously, and by described two ends to slow plane inclined of metal die face 123a or curved surface (be curved surface in this example) the formation inner cavity surface 102f that slowly tilts.Moreover, also can adopt between two ends of inner cavity surface 102f and the metal die face 123a and have some rugged structures, but in this structure, preferably rugged height is taken as and can not makes the degree that produces fold in the mould with face 131, bring the degree of obstacle promptly for the mould internal shaping.Jet tray 125 is configured between basal part 122 and the main part 123, it is moved between basal part 122 and main part 123, thereby the outer ejector pin of figure is stretched out toward the place ahead of main part 123 by injection molding machine 104.
As shown in Figure 3, film for internal mould mobile device 103 makes film for internal mould 131 each apotype internal shaping (1 time inject) only move the length (for example Fig. 8, length L shown in Figure 9) of regulation between fixation side metal pattern 111 and mobile side metal pattern 121.Here, as shown in Figure 9, film for internal mould 131 comprise resinous basilar memebrane 132, be formed on the patterned state of described essentially rectangular and wire with tin-doped indium oxide indium oxides such as (ITO) basilar memebrane 132 the surface nesa coating 3 and be formed on tack coat 134 on the nesa coating 3.Moreover, as the material that constitutes nesa coating 3, be not limited to above-mentioned indium oxide, also can have the various materials of the transparency and electric conductivity with the zinc oxide fine particles of the tin oxide particulate of antimony doped tin oxide (ATO) and fluorine doped tin oxide (FTO) etc., Al-Doped ZnO (AZO) etc. and cadmium oxide etc.
As an example, injection molding machine 104 is horizontal type injection molding machines, and its ingredient comprises fixation side installation portion, mobile side installation portion, clamping, injecting mechanism and injection equipment (all not shown) etc.Moreover, as injection molding machine 104, also can use the injection molding machine of longitudinal type; At this moment, described fixation side metal pattern 111 (with fixation side metal pattern 311 described later) is moved, mobile side metal pattern (with mobile side metal pattern 321 described later) is fixing.
Then, use manufacturing installation 101 (metal pattern 102) to make the operation of main part 1a and touch pad 1 with the intermediate manufacture method according to touch pad of the present invention with reference to description of drawings.
At first, as shown in Figure 3, fixation side installation portion outside the figure of injection molding machine 104 and mobile side installation portion are installed the fixation side metal pattern 111 and the mobile side metal pattern 121 of metal pattern 102 respectively.Next, film for internal mould 131 is placed film for internal mould mobile device 103, make tack coat 134 relative, make 103 work of film for internal mould mobile device with the inner cavity surface 102e of fixation side metal pattern 111.At this moment, film for internal mould mobile device 103 makes film for internal mould 131 only move the length of regulation between the fixation side metal pattern 111 of metal pattern 102 and mobile side metal pattern 121.Then, make 104 work of injection molding machine.At this moment, the clamping by injection molding machine 104 makes mobile side installation portion move toward the fixation side installation portion, thereby as shown in Figure 7, makes fixation side metal pattern 111 and mobile side metal pattern 121 to be bonded with each other under the state that sandwiches film for internal mould 131.In the case, in this metal pattern 102, two ends of the inner cavity surface 102f of the main part 123 of mobile side metal pattern 121 and and the metal die face 123a of these two end abutment between, the two sides does not have the ground that is uneven and connects continuously, and is made of two ends of inner cavity surface 102f the curved surface that metal die face 123a is slowly tilted.Therefore, prevent that positively the film for internal mould 131 that sandwiches as shown in Figure 7 from producing the state of affairs of fold.
Then, the resin of the injecting mechanism force feed flow state of injection molding machine 104.At this moment, the resin of injection molding machine 104 force feeds injects in inner chamber 102a from cast gate 102c by sprue 102b.In the case, as shown in Figure 7, in this metal pattern 102, except the inner cavity surface 102e side at film for internal mould 131 positions of living in and along the position of the width W 2 of the film for internal mould 131 of the length direction of inner cavity surface 102d cast gate 102c is set what be positioned at inner cavity surface 102d.Therefore, the resin one side of injecting in from cast gate 102c toward inner chamber 102a is pressed into inner cavity surface 102f side with film for internal mould 131, and one side is filled into inner chamber 102a.And the pressure of resin is close on the resin that is filled into inner chamber 102a the tack coat 134 that is clipped in the film for internal mould 131 between resin and the inner cavity surface 102f.
Then; after cool time through regulation; the clamping that makes injection molding machine 104 moves toward the direction that deviates from the fixation side installation portion, thereby removes engaging of fixation side metal pattern 111 and mobile side metal pattern 121, and makes mobile side metal pattern 121 leave fixation side metal pattern 111.At this moment, will separate from fixation side metal pattern 111 together with mobile side metal pattern 121 because of the formed products (promptly constituting the matrix part 2 of main part 1a) that resin solidification is shaped.Then, jet tray 125 past main part 123 side shiftings of the injection equipment of injection molding machine 104 by making mobile side metal pattern 121, thus the outer ejector pin of figure stretches out toward the place ahead of main part 123, takes out the matrix part 2 of shaping from mobile side metal pattern 121.In the case, because tack coat 134 is close to matrix part 2 (subsides), so film for internal mould 131 is taken out from mobile side metal pattern 121 together with matrix part 2.
Then, peel the basilar memebrane 132 of film for internal mould 131 from matrix part 2.In the case, because the state of the inside surface 21a of the panel part 21 that nesa coating 3 is bonded layer 134 is attached to matrix part 2 so peel basilar memebrane 132 from nesa coating 3 easily, makes nesa coating 3 be fitted in inside surface 21a.Thus, finish the manufacturing of the main part 1a of nesa coating 3 formations that comprise matrix part 2 and the inside surface 21a that is fitted in panel part 21 in the matrix part 2.Then, the outside surface 21b of opposite board 21 implements dura mater processing and antireflection processing.Then, the end face 21e of the panel part 21 in the matrix part 2 of main part 1a installs terminal for connecting 1b, and the nesa coating 3 of wire that will be fitted in the inside surface 21a of panel part 21 is connected with terminal for connecting 1b.Thus, finish touch pad 1.
In the case, as indicated above, this metal pattern 102 forms cast gate 102c on the inner cavity surface 102d that the end face 21c of the panel part 21 that makes main part 1a is shaped.Therefore, in main part 1a that makes by the mould internal shaping that uses this metal pattern 102 and the touch pad 1 of the 1a of the main consuming body portion, the gate vestiges 21d that produces during with the injection resin is formed on the end face 21c of panel part 21, makes the inside surface 21a of panel part 21 and the smooth state that outside surface 21b forms no gate vestiges.Thereby, avoid forming undesirable that gate vestiges causes at outside surface 21.Again, by the panel part 21 applying nesa coatings 3 of mould internal shaping in bending, nesa coating 3 becomes the state of thickness homogeneous in this touch pad 1.So this touch pad 1 can positively prevent the miswork that causes in uneven thickness of nesa coating 3.
Like this, among the main part 1a of this touch pad 1 and touch pad 1 usefulness, with the end face 21c of the inside surface 21a adjacency of the panel part 21 of applying nesa coating 3 on form gate vestiges 21d, and with its form position be defined in be positioned at panel part 21 except the outside surface 21b side of inside surface 21a and along the position of the width W 1 of the applying scope E1 of the length direction of end face 21c.Therefore, can be so that nesa coating 3 positively be fitted in the state of inside surface 21a with the inside surface 21a of panel part 21 and the smooth state of the no gate vestiges of outside surface 21b formation.As a result, finger tip contact gate vestiges and allow the user feel the state of affairs of not harmony in the time of positively avoiding the touch operation of outer surface 21b.And, main part 1a according to this touch pad 1 and touch pad 1 usefulness, inside surface 21a and outside surface 21b are smooth state, so can fully clearly see image that the inboard of the touch pad 1 that is encased in the mounting object thing shows etc., and can avoid the state of affairs that produces miswork that causes in uneven thickness of panel part 21 reliably.
Again, main part 1a according to this touch pad 1 and touch pad 1 usefulness, by panel part 21 is formed the tabular of bending, for example the radius gauge of panel part 21 is decided to be the identical curvature of curvature with the housing of mounting object thing, thereby the surface of the outside surface 21b of panel part 21 and housing becomes with one side, so the designability of mounting object thing is improved.In the case, utilize the panel part 21 applying nesa coatings 3 of mould internal shaping in bending, thus with utilize vapour deposition method or metallikon different in the structure that flexure plane forms nesa coating 3, can make nesa coating 3 be the uniform state of thickness.Thereby, according to the main part 1a of this touch pad 1 and touch pad 1 usefulness, can positively prevent the miswork that causes in uneven thickness of nesa coating 3.
Again, this metal pattern 102 and touch pad are with in the intermediate manufacture method, the inner cavity surface 102e side that is shaped at the outside surface 21b that makes panel part 21 except film for internal mould 131 positions of living in that is arranged in the inner cavity surface 102d that end face 21c that the inner cavity surface that constitutes inner chamber 102a makes panel part 21 is shaped and cast gate 102c is set along the position of the width W 2 of the film for internal mould 131 of the length direction of inner cavity surface 102d is injected resin from this cast gate 102c and is made matrix part 2 shapings.Therefore, the pressure of the resin during injection can make nesa coating 3 positively be fitted in the inside surface 21a of panel part 21, and gate vestiges 21d is formed on the end face 21c of panel part 21, the smooth state that the inside surface 21a and the outside surface 21b of panel part 21 can be formed no gate vestiges.As a result, can make and positively to avoid panel part 21 to form gate vestiges 21d causing unfavorable touch pad 1 main part 1a.
Again, according to this metal pattern 102 and touch pad intermediate manufacture method, two ends that make the inner cavity surface 102f that the position (scope of promptly fitting E1) of applying nesa coating 3 of the inside surface 21a of panel part 21 is shaped with and with the metal die face 123a of two end abutment between no rugged state continuously the two sides is connected, and constitute two ends of inner cavity surface 102f, thereby can prevent positively that the film for internal mould 131 that sandwiches from producing the state of affairs of fold by the curved surface that metal die face 123a is slowly tilted.
Then, illustrate that another routine touch pad of the present invention is with using forming metal mould and touch pad intermediate manufacture method in intermediate, touch pad, the mould.Moreover in the following explanation, to the component units mark prosign identical with above-mentioned touch pad 1 and manufacturing installation 101, the repetitive description thereof will be omitted.
