It is convexly equipped with to the right below right space and along the strip bulge 712 that de- material shank extends up and down, strip bulge 712 and left through-hole
Right side wall be closely fitted, the right side of coupler body 711 is in the right side of strip bulge right side, i.e. 711 left and right directions of coupler body
On width be more than the width on 712 left and right directions of bar shaped raised line, coupler body 711 be in below strip bulge 712, and convex with bar shaped
There is spacing between rising, so that positive stop lug boss is can extend into interior using this spacing, and moved up and down in it, opened on cope plate 14
Communicated with left through-hole equipped with one end, the other end passes to horizontal through-hole outside cope plate left side wall, elastomer 72 is lying in horizontal through-hole
It is interior, elastomer 72 it is excellent it is good be spring, and the left side wall of the right end end of spring and de- material shank 71 mutually supports cooperation, in horizontal through-hole
It is screwed with the lock screw 73 mutually supported with the left end end of spring.In application, convex using the elastic pressure of spring and bar shaped
Play 712 makes de- material shank 71 not occur to swing easily under the action of smaller external force with the snug fit of left through-hole right side wall,
Safe operation, conveniently.
The positive stop lug boss is accordingly at the left side of lower die structure, lower template 21, lower backboard 22 and lower clamp plate 23
Left side be located at be recessed with to the right at the position of de- material shank 71 for de- material shank activity be inserted into recess (do not show in figure
Go out), the left side wall of lower template 21 is located at the depressed area of lower template is convexly equipped with convex block 211 to the left, this convex block 211 is described
Positive stop lug boss；Lower template 21 covers 27 in through-hole embedded with guide support, and the top surface of guide support set 27 upwardly extends
It projects through and is lain against for cell phone rear cover 100 outside through-hole, and tight fit stretches into the support ring 271 in molding cavity 31, this
Support ring is in the closed-loop shaped structure to match with mobile phone shape, i.e. 100 gusset of cell phone rear cover overlays in support ring, after mobile phone
Lid 100 is firm to be placed, and lower de- plate 4 is in this guide support set 27, and support ring 271 is stretched out on the top of lower de- plate 4 upwards
Outside.
Have the upper cutting for tilting down and extending at positive stop lug boss left side oblique on the left of the top surface of the positive stop lug boss
Face 211a, the bottom surface of coupler body 711 have upwards that inclination extends at coupler body right side, and with the incision of upper cutting slopes which match
Inclined-plane 711a is cut, upper cutting inclined-plane 211a constitutes the lower guiding with lower cutting inclined-plane 711a and crosses structure, corresponding bar shaped
The bottom surface of protrusion 712 is in acclivitous inclined surface, the angle of inclination at the angle of inclination of inclined surface and upper cutting inclined-plane 211a
It matches；It is in the first arc transition 211b of convex, top surface and the right side of coupler body 711 between the bottom surface and left side of positive stop lug boss
In convex between side, and the second the arc transition 711b, the first arc transition 211b to match with the first arc transition
The upper guiding, which is constituted, with the second arc transition 711b crosses structure.The guiding crosses the setting means of structure using existing
The guiding technique means that mutually push-and-pull fastens, are not repeated herein.
The novel diel back to squeeze of one kind of the utility model, cell phone rear cover 100 to be formed is kept flat and is sleeved on lower take off
Outside the top surface of plate 4, the top surface of the inner surface of cell phone rear cover 100 and lower de- plate 4 is affixed identical, and upper die structure 1 is to lower die knot later
2 direction of structure moves down, and when the coupler body 711 of de- material shank 71 is moved to above positive stop lug boss in folding process, positive stop lug boss limits coupler body
Move down, at this point, when upper die structure 1 continues to move down, because lower cutting inclined-plane 711a with upper cutting inclined-plane 211a is tangent is bonded, and utilize
Inclined-plane characteristic makes positive stop lug boss make have thrust to the left to de- material shank 71, and the upper end of de- material shank 71 is movably hinged, and limits
Position boss makes the lower part of de- material shank 71 swing to the left, and spring accordingly compresses to the left, coupler body 711 accordingly to moving to left certain position,
Coupler body is able to cross positive stop lug boss, and more spring-return, restoring force make coupler body return to initial position later, and the right side of coupler body is in
On the right side of the left side of positive stop lug boss, finally, upper die structure 1 continues to move down, and the upper end end of lower de- plate 4 is together with cell phone rear cover 100
Stretch into together in molding cavity 31, the outer surface of cell phone rear cover 100 be affixed with the chamber for being molded cavity 31 it is identical, at this point, upper mold
Structure continues to move down, and 100 gusset end face of cell phone rear cover is stacked cooperation with support ring 271, and lower de- plate 4 is pushed down on by upper de- plate
Pressure, upper spring and lower nitrogen gas spring are compressed, and make cell phone rear cover 100 using the lower pressure of upper de- plate and the upper pressure of lower de- plate
Be able to punch forming back to squeeze, make cell phone rear cover be stamped it is back to squeeze go out its big face and the rectangular transition in four sides shaping mobile phone after
Lid；After molding, upper die structure is to moving up, and upper spring, which pushes, takes off plate to moving down, and de- plate takes off to moving up under lower nitrogen gas spring pushes
Material shank 711 accordingly moves up, and coupler body and the positive stop lug boss phase hook of de- material shank 711 can not be separated, at this time lower die knot
Downward pulling force is formed between structure and de- material shank, upper die structure needs increase pulling force that can just make de- material shank and lower die structure
Phase separation, then while upper die structure firmly pulls up, the downward restoring force of upper spring and the upward restoring force of lower nitrogen gas spring,
While so that de- material shank is mutually broken off relations with positive stop lug boss, shaping mobile phone rear cover is separated with upper de- plate and lower de- plate, is molded hand
Machine rear cover is supported ring 271 and fixes support, and molding mobile phone can be made by so that upper die structure is once divided with lower die structure while mould
Rear cover detaches jointly from upper de- plate and lower de- plate.Compared with prior art, the mold back to squeeze of the utility model, upper die structure with
While lower die structure phase demoulding molding cell phone rear cover can detach from upper de- plate and lower de- plate, make cell phone rear cover
It need to only be no longer needed to by multiple ability demoulding back to squeeze, to make the straight of whole mobile phone rear cover by primary operation back to squeeze
Angle molding only needs to be molded by two times punch and primary punching press back to squeeze, and molding procedure is few, and the molding used time is short, and yield is high；
In addition, in overall structure, the setting covered by guide support can further promote the demoulding of cell phone rear cover, and make the hand after demoulding
Machine rear cover is placed in steady.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
