Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figures 1 to 6, a kind of metal wire bullet ripple forming mould of the present utility model, comprise upper die body 1 and lower mold body 2, upper die body 1 and lower mold body 2 are provided with forming surface, described upper die body 1 offers the first mold insert chamber 11, being provided with in described first mold insert chamber 11 can the mold insert 3 of elasticity activity up and down, and mold insert 3 protrudes from the forming surface of upper die body 1, and the forming surface of mold insert 3 is positioned at the below of the forming surface of upper die body 1.A kind of metal wire bullet ripple forming mould of the present utility model, during work, playing ripple cloth is positioned between upper die body 1 and lower mold body 2, lower mold body 2 moves downward and drives mold insert 3 to move downward simultaneously, the position of the forming surface of the mold insert 3 arranged due to upper die body 1 is lower than the position of the forming surface of upper die body 1, namely the forming surface of mold insert 3 is first suppressed and is played ripple cloth, then the forming surface of upper die body 1 is suppressed and is played ripple cloth, finally play ripple cloth compressing, after completing separate room bullet wave pressure work, upper die body 1 rises, mold insert 3 elastic reset, guarantee the position of the position of the forming surface of mold insert 3 lower than the forming surface of upper die body 1.Metal wire bullet ripple forming mould of the present utility model, can the mold insert 3 of elasticity activity up and down by arranging in upper die body 1, realize when suppressing bullet ripple cloth, suppress gradually from the inside playing ripple cloth toward outside, guarantee shaping after bullet ripple normally form wave-like, the situation avoiding bullet ripple cloth and metal wire to be pressed down occurs, and guarantees the yields of the bullet ripple produced.
In the present embodiment, described mold insert 3 comprises the first mold insert 31 and the second mold insert 32, first mold insert 31 is positioned at the first mold insert chamber 11, first mold insert 31 and upper die body about 1 elastic movable supports, first mold insert 31 offer the second mold insert chamber 311, second mold insert 32 be positioned at the second mold insert chamber 311 and with upper die body about 1 elastic movable supports; The forming surface of the second mold insert 32 is positioned at the top of the forming surface of the first mold insert 31, and is positioned at the below of forming surface of upper die body 1; Concrete, when carrying out the work of bullet wave pressure system, the inside of the first compressing bullet ripple of forming surface of the second mold insert 32, then the middle part of the forming surface of the first mold insert 31 compressing bullet ripple again, the external position of the compressing bullet ripple of the forming surface of last upper die body 1, play the compressing difference of ripple from inside to outside, namely ripple is played when becoming undulate shape, from inner toward dimensional deformation, thus bullet ripple first shape from outside the bullet ripple cloth of the inside compacting caused and the stable generation of metal wire fracture can be efficiently avoid, guarantee the yields playing wave pressure.
In the present embodiment, the top of described upper die body 1 offers the first perforation 12 and the second perforation 13, the first screw 121 is provided with in first perforation 12, bottom and first mold insert 31 of the first screw 121 are spirally connected, the two ends being up and down arranged with the first spring 122, first spring 122 outside first screw 121 abut with the first mold insert 31 and upper die body 1 respectively; The bottom and the second mold insert 32 that are provided with the second screw 131, second screw 131 in second perforation 13 are spirally connected, and the two ends being up and down arranged with the second spring 132, second spring 132 outside the second screw 131 abut with the second mold insert 32 and upper die body 1 respectively; Concrete, during inactive state, first mold insert 31 is supported downward state by the elastic force of the first spring 122, second mold insert 32 is supported downwards by the elastic force of the second spring 132, and when carrying out the work of bullet wave pressure system, the second mold insert 32 is suppressed and played ripple cloth, simultaneously, second mold insert 32 moves upward under reaction force, and compress the second spring 132, second screw 131 second perforation 13 in move upward; Then, first mold insert 31 is suppressed and is played ripple cloth, and meanwhile, the first mold insert 31 moves upward under reaction force, and compress the first spring 122, first screw 121 moves upward in the first perforation 12, and finally, upper die body 1 is suppressed and played ripple cloth, sequentially compacting plays ripple cloth from inside to outside, guarantee shaping after bullet ripple there will not be damage, reasonable in design, practical.
In the present embodiment, described lower mold body 2 is provided with alignment pin, and mold insert 3 is provided with the location hole corresponding with alignment pin; During work, when upper die body 1 and lower mold body 2 compress mutually, dowel and location hole cooperatively interact, guarantee that playing ripple cloth can be positioned to play on ripple mould exactly further, further, can prevent playing ripple mould and bullet ripple cloth is crushed, thus reduce the defective products rate playing ripple and produce.
In the present embodiment, the forming surface of described upper die body 1 and the forming surface of mold insert 3 offer interconnective upper metal raceway 14, and the forming surface of lower mold body 2 offers the lower metal raceway 21 corresponding with upper metal raceway 14; Concrete, when upper die body 1 and lower mold body 2 will play ripple cloth compresses time, the metal wire be sewn on bullet ripple cloth is positioned in the cavity that metal raceway 14 and lower metal raceway 21 be combined to form exactly, and finally bullet ripple cloth is at the compacting compacted under of mould.The plain conductor that this kind of structural design can exactly positioning ejection ripple cloth be sewed up, prevent from further playing ripple cloth when compressing, directly weigh or break the plain conductor being sewn to and playing on ripple cloth wounded, and ensure to offset because of playing the plain conductor that ripple is sewed up and to affect the tonequality of loud speaker, improve the quality of production playing ripple further.
In the present embodiment, described upper die body 1 is coaxially arranged with lower mold body 2; Coaxially arrange upper die body 1 and lower mold body 2 can make when upper die body 1 and lower mold body 2 mutually compresses plays ripple cloth time, can effectively avoid playing ripple mould bullets ripple cloth is pressed inclined, crush, thus the quality of raising bullet ripple.
Known the utility model is have above-described good characteristic in sum, is made it in use, promotes in conventional art the usefulness that do not have and has practicality, becoming the product that has practical value.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
