[embodiment]
Yi Xia embodiment for convenience of description, components identical is represented with identical label.
As shown in Figure 2, the forming method of first embodiment of the invention composite key includes material preparation step, shell forming step, die sinking step, die change step, inner casing forming step and gets finished product die sinking step.The following example of the present invention graphic all has only the keyboard of demonstration, but reality can be made many keyboards at the same time, comprises numeral, function key or the like as the button of portable phone.
Material preparation step: cooperate and consult Fig. 3, Fig. 4 and shown in Figure 5, prepare most watchcases unit 10 in advance and prepare an ejaculation equipment 100, this watchcase unit 10 is back to vacuumize with the watchcase base material 10 ' heating of rigid plastics film, take out type, mode such as punching press or high pressure blow-gas is made, have most watchcases 11 after 10 moulding of watchcase unit and link a link piece 12 of these watchcases 11, this watchcase 11 includes the perisporium 112 that a roof 111 and is connected with link piece 12 by this downward extension of roof 111 peripheries and root edge, the two matches and defines a shrinkage pool 113, this roof 111 bottom surfaces or extend to perisporium 112 medial surfaces, link piece 12 bottom surfaces are provided with a character pattern layer 13, this literal patterned layer 13 can be in watchcase unit 10 as yet not hot briquetting promptly be attached to watchcase base material 10 ' bottom surface in the past with mode of printing, perhaps can after 10 moulding of watchcase unit, be printed on roof 111 bottom surfaces again.This ejaculation equipment 100 include one fixedly die holder 110 and be positioned at same axis and can produce the movable die holder 120 of closure, unlatching vertically relatively, this fixedly die holder 110 be respectively equipped with one corresponding to end face both sides of axis and have the shell mould portion unit 130 and that majority is projection shape shell mould portion 131 and have the inner casing mould portion unit 140 that majority is shrinkage pool shape inner casing mould portion 141.This activity die holder 120 corresponding to the both sides, a bottom surface of axis also respectively be provided with can be outer with this, first and second positioning unit 150,160 that inner casing mould portion unit 130,140 is relative, the bottom surface of the corresponding shell mould of this first and second positioning unit 150,160 portion 131, inner casing mould portion 141 also all is concaved with and is first and second poroid die cavity 151,161 of ladder.
Shell forming step: as shown in Figure 5, be under the opening at ejaculation equipment 100, and when the shell mould portion unit 130 of first positioning unit 150 that makes this activity die holder 120 and fixing die holder 110 is relative, this watchcase unit 10 is positioned in this first die cavity 151, again as shown in Figure 6, produce closed towards fixing die holder 110 movable die holder 120, utilize an ejecting device (figure does not show) that the Merlon raw material is imported between watchcase unit 10 and the shell mould portion 131, make and respectively form a hard shell 20 with suitable thickness in the shrinkage pool 113 of this watchcase unit 10, and this shell 20 has rigidity, maybe can adopt the plastic raw materials of propylene-BS.At this moment, be the idle stroke state between second die cavity 161 of ejaculation equipment 100 opposite sides and the inner casing mould portion 141, do not shoot material.
Die sinking step: movable die holder 120 is separated with fixing die holder 110, then be provided with a keyboard semi-finished product unit I of tool watchcase unit 10 and most shell 20 in first die cavity 151 of first positioning unit 150.
Die change step: as shown in Figure 7, this activity die holder 120 rotates 180 degree, and make the fixedly inner casing mould portion unit 140 of die holder 110 of first positioning unit 150 and keyboard semi-finished product unit I transfer back symmetry, and second positioning unit 160 with should be fixedly the shell mould portion unit 130 of die holder 110 when relative, again with in sheathed second die cavity 161 that is positioned at this second positioning unit 160 in another watchcase unit 10.
Inner casing forming step: as shown in Figure 8, ejaculation equipment 100 is closed once more, these keyboard semi-finished product unit I is to being combined in this inner casing mould portion unit 140, utilize an ejecting device that the thermoplastic rubber raw material is imported between keyboard semi-finished product I and the inner casing mould portion 141 to form a soft inner casing 30, make this inner casing 30 have elasticity, simultaneously, watchcase 11 inside of second positioning unit 160 of opposite side also utilize ejecting device that the plastic raw materials of Merlon or propylene-BS is imported to form another hard shell 20, then also are provided with a keyboard semi-finished product unit I of tool watchcase unit 10 and most shell 20 on second positioning unit 160.
Get finished product die sinking step: as shown in Figure 9, this activity die holder 120 can take out a keyboard and become article unit II, and still be detained a keyboard semi-finished product unit I on second positioning unit 160 with after fixedly die holder 110 separates on this first positioning unit 150.
Whereby, when cycling die change step, inner casing forming step, get finished product die sinking step, promptly can the automated job mode in the watchcase unit 10 inner hard shells 20, the soft inner casings 30 of penetrating continuously to make the purpose that keyboard becomes article unit II.
As shown in figure 10, this keyboard becomes article unit II from top to bottom to include a watchcase 11, a character pattern layer 13, a hard shell 20 and a soft inner casing 30.This hard shell 20 has suitable thickness, so the operator is when pushing keyboard, can not produce the signature trace, the cross section of hard shell 20 is inverted U, convex with a joint portion 21 under the one bottom surface mediad, the bond strength of borrowing this joint portion 21 can strengthen shell 20 and inner casing 30, and soft inner casing 30 bottoms are provided with a conducting portion 31 of convex shape, set contact position on the turning circuit plate smoothly.
Therefore, the made keyboard of the present invention not only has the effect that prevents to give as security the trace generation, and changes by the rotation of same ejaculation equipment 100, can be at watchcase 11 inner hard shells 20 and the soft inner casings 30 of penetrating continuously, and speed of production is fast, production capacity is high.
Utilize above-mentioned manufacturing step, and cooperate difform shell mould portion, inner casing mould portion, can be made into difform keyboard and become article unit.As shown in figure 11, a keyboard becomes a shell 201 cross sections of article unit III to be inverted U, and shell 201 bottom surfaces are smooth with an inner casing 301 end faces and engage.Again as shown in figure 12, a keyboard becomes the shell 202 of article unit IV to be plate-like, and make inner casing 302 side faces directly and character pattern layer 13 fixed.And for example shown in Figure 13, it also is to be inverted U that one keyboard becomes the cross section of the shell 203 of article unit V, but this inner casing 303 is rabbeted shell 203 inside except the top, outer peripheral face is protruding watchcase 11 outsides that are exposed at fully, thus, this keyboard becomes article unit V to be applicable to be fitted in higher position, and the inner casing 303 of collocation differing heights can make keyboard arrange to be the moulding with curve.
Conclude above-mentionedly, the forming method of composite key of the present invention has simple manufacturing step, can promote speed of production and promote production capacity, can reach its intended purposes really.
