Abstract

The utility model discloses a loudspeaker elastic wave molding pressing die, consisting of an upper die part and a lower die part, wherein, the lower die part is composed of a lower die head, a movable pressing sleeve, an offsetting spring and a lower die plate, wherein, the lower die head comprises a molding die body and a bearing column; the molding die body is composed of a lower molding face and a lower pressing ring; the movable pressing sleeve is sleeved on the molding die body and the bearing column; the offsetting spring is sleeved on the bearing column and between the movable pressing sleeve and the lower die plate; an upper die head is coaxial with the lower die head. Because the movable pressing sleeve and the offsetting spring are added in the lower die head part, when the elastic wave is pressed, to-be-molded cloth blank is pressed by an upper pressing ring and the movable pressing sleeve to make the edge of the cloth blank be stressed evenly, and then the cloth blank is stretched, pressed and molded, thereby the elastic wave finished product is prevented from being folded at the edge; the whole process is completed by one operator, and the finished product can be demoulded automatically; the operation is safe, convenient and laborsaving.

Description

Loudspeaker play-wave moulding compacting tool set

Technical field:

The utility model relates to a kind of mould, relates in particular to a kind of loudspeaker play-wave moulding compacting tool set.

Background technology:

Loud speaker also claims loudspeaker, it is a kind of mechanical device that electrical signal is transformed into the sound equipment vibrations, and loudspeaker will come out sound playing, must comprise loudspeaker monomer and sound equipment, just so-called loudspeaker, the prior art of loudspeaker is very ripe, but the key factor that the tonequality of loudspeaker is considered when being horn designs, the bullet ripple of loudspeaker, voice coil loudspeaker voice coil, drum paper and binding agent all can influence the tonequality quality.Bullet ripple on the loudspeaker generally heats compression moulding behind the fiber cloth drawn by band glue, the material of good springiness such as fiber cloth such as cotton yarn, the dimity, nylon, playing ripple is installed between speaker body and the 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, and it is made up of corrugated plating 91, waist body 92 and flanging 93.Existing bullet ripple moulding compacting tool set as shown in Figure 2, it is made up of upper mould part and lower mould part, upper mould part is made up of cope match-plate pattern 2 and last die head 3, last die head 3 is fixed on the cope match-plate pattern 2; Lower mould part is made up of lower die head 4 and lower bolster 7, and lower die head 4 is fixed on the lower bolster 7.In pressing process, the flanging 93 around the bullet ripple and the bottom of waist body 92 are easy to produce fold, the possibility of the big more generation fold of waist body drop difference height of bullet ripple is just big more, fold is just serious more, and this is to play the master operation that produces waste product or defective products in the ripple production process at present, produces this class defective, 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 influences the tonequality and the outward appearance of loud speaker.The existing simultaneously ripple moulding compacting tool set that plays plays in the process of ripple in compacting, must want two people's co-operations, if cooperate the bad industrial accident that is easy to take place, all can bring very big injury and loss for operator and enterprise.

The utility model content:

In order to overcome the existing the problems referred to above that the wave pressure molding jig exists that play, the utility model provides a kind of loudspeaker play-wave moulding compacting tool set, adopt this one-tenth pressing mold tool, can eliminate the wrinkling defective in the wave pressure system of the bullet process, greatly reduce percent defective and defective products rate, thereby improve the tonequality and the outward appearance of loud speaker, simultaneously, this mould is as long as a people just can operate smoothly, and finished product can eject automatically, need not manual depanning, has both saved artificial, improved the fail safe of operation again, for manufacturer has saved cost.

The technical scheme that the utility model adopted is:

Described loudspeaker play-wave moulding compacting tool set, comprise upper mould part and lower mould part, upper mould part comprises die head and cope match-plate pattern, cope match-plate pattern is fixedly mounted on the expansion link of make-up machine, last die head is fixedly mounted on the lower surface of cope match-plate pattern, and last die head is made up of last forming surface and last trim ring, and the shape of last forming surface is consistent with the upper surface shape of the corrugated plating that plays ripple, the width of last trim ring is greater than the width of the flanging that plays ripple, and the distance of last trim ring and last forming surface equals to play the height of the waist body of ripple; Lower mould part comprises lower die head and lower bolster, lower bolster is fixedly mounted on the workbench of make-up 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, and the distance of lower clamping ring and compacted under face equals to play the height of the waist body of ripple, last die head and the coaxial installation of lower die head; It is characterized in that: in lower mould part, also comprise mobile gland and back-moving spring, 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 last die head, the upper end endoporus of mobile gland cooperates with the shaping mould body space of lower die head, the lower end endoporus of mobile gland cooperates with pressure-bearing intercolumniation crack, 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 last forming surface of lower die head moulding die body.

Owing in the lower die head parts of existing bullet ripple moulding compacting tool set, increased mobile gland and back-moving spring, when compacting plays ripple, the last trim ring of last die head and the upper surface of mobile gland compress cloth material base to be formed earlier, make the cloth of periphery evenly stressed, and then pull and stretch compression moulding, so just can eliminate the wrinkling reason of the wave pressure system of bullet, can not only reduce the generation of waste product and defective products significantly, and the bullet ripple finished product that suppresses depanning automatically, need not manual depanning, simple to operate, and, improved the fail safe of operation as long as a people can operate.The bullet ripple no wrinkle that suppresses by the utility model, can prevent that loud speaker is when glue is played in assembling, be connected not tight with voice coil loudspeaker voice coil because of flanging has the folding bullet ripple that causes, cause playing the undesired vibration of ripple, thereby influence the tonequality and the outward appearance of loud speaker, this mould is applicable to the drawing and forming of soft thin base parts such as cloth, aluminium sheet, copper coin.
