In the operation upper tablet being fused to band muscle, be first to treat that the upper tablet of welding is delivered in a counterdie, to utilize tablet in this counterdie support; This counterdie is gone back the slide fastener that support needs to be installed tablet, then the band muscle of slide fastener is moved in the opening of upper tablet, now go up tablet and the preparation of being with muscle to carry out welding; Finally utilize a soldering tip from top to bottom to be pressed in tablet, ultrasonic fusing is carried out to upper tablet, make its welding on band muscle.
Existing counterdie, the general upper tablet only treating welding plays the effect of support, and does not possess the function fixing upper tablet, thus band version of tendon and muscle turn or on tablet carry out in the process of hot pressing, easily there is change in location in upper tablet, often causes occurring tablet welding defective products.Also have part counterdie, in support, the position of tablet is provided with groove, can play certain positioning action, but fixes poor effect, or the phenomenon of upper tablet off normal can often occur, and still cannot meet the requirement of upper tablet welding yields.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of counterdie for the welding of top zipper stop grain, and the upper tablet that this counterdie can treat welding plays good fixing effect.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: for the counterdie of top zipper stop grain welding, comprise lower mold body, this lower mold body is provided with the projection for propping up upper tablet, also be provided with the clamping mechanism coordinating with described projection and fix tablet in this lower mold body, this clamping mechanism comprises the extensible member that can to coordinate with described projection when stretching out lower mold body and to fix tablet and impels this extensible member to stretch out the elastic component of lower mold body.
Described extensible member is the inclined-plane be tilted down along the direction away from upper tablet for fixing the end face of the end of upper tablet.
Be provided with the accommodating cavity that can hold described extensible member, described elastic component in described lower mold body, described extensible member, for the end that the fixes upper tablet body fit corresponding with this accommodating cavity, can slide along accommodating cavity to make extensible member and stretch out lower mold body.
Described accommodating cavity is provided with a detachable plug near the opening of elastic component.
Described extensible member is shaft-like, and this extensible member is less near the end size of described elastic component, and form head shoulder, described elastic component is resisted against this shoulder to actuate described extensible member.
Described elastic component is helical spring, and the smaller end of described extensible member puts in this spring.
The utility model by arranging clamping mechanism in lower mold body, utilize this clamping mechanism to coordinate with projection, can will treat that the upper tablet of welding is very firmly stuck in counterdie, can not there is change in location in upper tablet more easily, therefore, it is possible to effectively promote upper tablet welding yields, to meet production requirement.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1,2,3,4, the utility model is used for the counterdie of top zipper stop grain welding, comprise lower mold body 20, the centre position of the upper surface of this lower mold body 20 is provided with the projection 21 of fore-and-aft direction protruding upward, and this projection 21 is for propping up the bend 11 of tablet on U-shaped.
Two accommodating cavities 22 of symmetrical up/down perforation are provided with in lower mold body 20, clamping mechanism 30 is all accommodated in two accommodating cavities 22, this clamping mechanism 30 forms by shaft-like extensible member 31 with as the helical spring 32 of elastic component, the body fit that the top 311 of this extensible member is corresponding with accommodating cavity 22, can slide up and down along accommodating cavity 22 to make extensible member 31, the radial dimension of the bottom 312 of extensible member is less than the radial dimension on the top 311 of extensible member, makes extensible member 31 form head shoulder 313 at medium position; Spring 32 is arranged on the below of extensible member 31, and the bottom 312 of extensible member puts in this spring 32, and spring 32 can be made to entangle the extensible member 31 of part; The detachable plug 23 be threaded with lower mold body 20 is provided with under shed 221 place of the below of spring 32, accommodating cavity, the under shed 221 that this plug 23 both can open accommodating cavity can load the accommodating cavity 22 of lower mold body 20 under shed to make extensible member 31, spring 32, again can the under shed 221 of shutoff accommodating cavity, to spring 32 to support.
The bottom 321 of spring is pressed on plug 23, and the upper end 322 of spring is resisted against the head shoulder 313 of extensible member 31, forms the motive force to extensible member 31 with this, stretches out lower mold body 20 to impel extensible member 31 along accommodating cavity 22 upward sliding.The upper end 314 of extensible member protrudes upward lower mold body 20 to prop up the line part 12 U-shaped being positioned at below in tablet, and the upper end 314 of extensible member coordinates with projection 21 and tablet on U-shaped 10 fixed in lower mold body 20.
For ensureing that the band muscle of slide fastener can be advanced on U-shaped in tablet 10 by band version of tendon and muscle material bar 40 smoothly from the opening portion 13 of tablet U-shaped, it is the inclined-plane be tilted down along the direction away from tablet on U-shaped 10 that extensible member 31 stretches out lower mold body 20 for propping up the end face 315 of the upper end of tablet 10 on U-shaped, like this when being with version of tendon and muscle material bar 40 push belt version of tendon and muscle to enter tablet 10 on U-shaped, can along this inclined-plane, extensible member 31 be pressed downward in lower mold body 20 very swimmingly, after band version of tendon and muscle material bar 40 exits, extensible member 31 stretches out tablet 10 on lower mold body 20 pairs of U-shapeds and fixes under the promotion of spring 32.
The above, it is only a kind of preferred embodiment of the utility model, not technical scope of the present utility model is imposed any restrictions, every embodiment is above done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of the utility model technology.
