Abstract

The invention provides a press-forming mould of a loudspeaker elastic wave, comprising an upper mould component and a lower mould component. The lower mould component comprises a lower mould head, a movable press sleeve, return springs and a lower template, wherein the lower mould head comprises a moulding body and a bearing column; the moulding body comprises a lower moulding surface and a lower press ring; the movable press sleeve is sleeved on the moulding body and the bearing column; the return springs are sleeved on the bearing column and positioned between the movable press sleeve and the lower template; and the upper mould head and the lower mould head are coaxial. The movable press sleeve and the return springs are added to the lower mould head so that, in the operation of pressing an elastic wave, the upper press ring and the movable press sleeve first press cloth blanks to be moulded tight and ensure that peripheral cloth receives even force; and then the cloth blanks are deeply drawn and pressed to form a finished product so that the folds of the peripheral parts of the finished product of elastic wave can be eliminated. The press-forming mould of the invention can be operated by only one person; and moreover, the finished product can be automatically demoulded, which provides safe, convenient and labor-saving operation.

Description

Press-forming mould of loudspeaker elastic wave
Technical field:
The present invention relates to a kind of mould, relate in particular to a kind of press-forming mould of loudspeaker elastic wave.
Background technology:
Loud speaker also claims loudspeaker, it is a kind of mechanical device that electrical signal is transformed into to the sound equipment vibrations, and loudspeaker will play back sound, must comprise horn single body and sound equipment, so-called loudspeaker namely, the prior art of loudspeaker is very ripe, but the key factor that the tonequality of loudspeaker is considered while being horn designs, the bullet ripple of loudspeaker, voice coil loudspeaker voice coil, drum paper and binding agent all can affect the tonequality quality.Bullet ripple on loudspeaker is generally compressing by heating after the fiber cloth drawn with glue, fiber cloth is as the material of the good springiness such as cotton yarn, the dimity, nylon, playing ripple is arranged between speaker body and voice coil loudspeaker voice coil, work to connect and support voice coil loudspeaker voice coil, as Fig. 1 is a kind of bullet wave structure schematic diagram, it is comprised of corrugated plating 91, waist body 92 and flanging 93.As shown in Figure 2, it is comprised of upper mould part and lower mould part existing bullet ripple forming mould, and upper mould part is comprised of cope match-plate pattern 2 and upper die head 3, and upper die head 3 is fixed on cope match-plate pattern 2; Lower mould part is comprised of lower die head 4 and lower bolster 7, and lower die head 4 is fixed on lower bolster 7.In pressing process, play the flanging 93 of ripple surrounding and the bottom of waist body 92 and be easy to produce fold, the possibility of the larger generation fold of the poor height of waist body drop of bullet ripple is just larger, fold is just more serious, and this is to play at present the master operation that produces waste product or defective products in the ripple production process, produces this class defect, play ripple when glue is played in the loud speaker assembling, will make to play ripple and be connected not closely with voice coil loudspeaker voice coil, causing playing ripple can not normal vibration, thereby affects tonequality and the outward appearance of loud speaker.The existing ripple forming mould that plays plays in the process of ripple in compacting simultaneously, must want two people's co-operations, if coordinate the bad industrial accident that is easy to occur, all can bring very large injury and loss to operator and enterprise.
Summary of the invention:
In order to overcome the existing the problems referred to above that the wave pressure molding jig exists that play, the invention provides a kind of press-forming mould of loudspeaker elastic wave, adopt this one-tenth compression mould, can eliminate the wrinkling defect played in wave pressure process processed, greatly reduce percent defective and defective products rate, thereby improve tonequality and the outward appearance of loud speaker, simultaneously, this mould is as long as a people just can operate smoothly, and finished product energy automatic spring, without manual depanning, both saved artificial, improved again the fail safe of operation, for manufacturer has saved cost.
The technical solution adopted in the present invention is:
Described press-forming mould of loudspeaker elastic wave, comprise upper mould part and lower mould part, upper mould part comprises upper die head and cope match-plate pattern, cope match-plate pattern is fixedly mounted on the expansion link of forming machine, upper die head is fixedly mounted on the lower surface of cope match-plate pattern, and upper die head is comprised of upper forming surface and upper trim ring, and the shape of upper forming surface is consistent with the upper surface shape of the corrugated plating that plays ripple, the width of upper trim ring is greater than the width of the flanging that plays ripple, the height apart from the waist body that equals to play ripple of upper trim ring and upper forming surface; Lower mould part comprises lower die head and lower bolster, lower bolster is fixedly mounted on the workbench of forming machine, lower die head is fixedly mounted on the upper surface of lower bolster, lower die head comprises compacted under face and lower clamping ring, the shape of compacted under face is consistent with the lower surface shape of the corrugated plating that plays ripple, the width of lower clamping ring is identical with the flanging width that plays ripple, the height apart from the waist body that equals to play ripple of lower clamping ring and compacted under face, and upper die head and lower die head are coaxially installed; It is characterized in that: also comprise mobile gland and back-moving spring in lower mould part, the wall body cross sectional shape of mobile gland is L shaped, the upper end external diameter of mobile gland is suitable with the external diameter of upper die head, the upper end endoporus of mobile gland coordinates with the shaping mould body space of lower die head, the lower end endoporus of mobile gland coordinates with pressure-bearing intercolumniation gap, back-moving spring is sleeved on the pressure-bearing post, and between mobile gland lower surface and lower bolster upper surface, under the normality condition, the upper surface of mobile gland is higher than the peak of the upper forming surface of lower die head moulding die body.
Owing in the lower die head parts at existing bullet ripple forming mould, having increased mobile gland and back-moving spring, when compacting plays ripple, the upper trim ring of upper die head and the upper surface of mobile gland first compress cloth material base to be formed, make peripheral cloth uniform stressed, and then pull and stretch is compressing, so just can eliminate the wrinkling reason of the wave pressure system of bullet, can not only significantly reduce the generation of waste product and defective products, and the bullet ripple finished product suppressed depanning automatically, without manual depanning, simple to operate, and, as long as a people can operate, improved the fail safe of operation.The bullet ripple no wrinkle suppressed by the present invention, can prevent that loud speaker is when glue is played in assembling, because flanging has the folding bullet ripple caused, with voice coil loudspeaker voice coil, be connected not tight, cause playing the undesired vibration of ripple, thereby affect tonequality and the outward appearance of loud speaker, this mould is applicable to the drawing and forming of the soft thin base parts such as cloth, aluminium sheet, copper coin.
The accompanying drawing explanation:
Fig. 1 is for playing a kind of structural representation of ripple;
Fig. 2 is the existing structural representation that plays the ripple mould;
