Further, several limits for limiting hollow deckle board falling head are respectively provided with outside several described support springs Position set, several described stop collar lower ends are installed in die holder upper surface, several stop collar upper surfaces with hollow deckle board Following table interplanar distance is set.The design can not only limit hollow deckle board falling head, but also protection can be played to support spring Effect.
Preferably, when the hollow deckle board declines, lower mold core upper surface is higher by hollow deckle board upper surface, and with middle empty frames Plate upper surface forms punch surface;The eedle presser lower surface is higher by red needle plate lower surface, and is formed with red needle plate lower surface recessed Model face.The design can when the hollow deckle board of eedle presser punching press causes its decline, for being punched side more than wiring board side, and After upper mold rises and removes to the pressure of middle empty frames plate, after causing it to rise under support spring effect, lower mold core upper surface is with Empty frames plate upper surface flush, can jack up the remaining side after punching to clear up.
Preferably, the lower mold core is equipped with several material-dropping holes, the material-dropping hole is from lower mold core upper end to lower mold core Lower end gradually expands, and the blanking hole being adapted is correspondingly provided with the die holder.The design can avoid blanking from blocking material-dropping hole.
Further, die holder lower surface both sides are equipped with two support beams, and blanking is formed between two support beams Space.The design can avoid die holder from causing blanking hole plug after installing.
The utility model uses above technical scheme, using the upper die and lower die of split structure, can not only substitute biography The integral structure of system, consequently facilitating carry out the maintenance and replacement of local parts, and the needle plate that can only need to liquidate, red needle, The core components such as lower mold core are molded using high-quality high low cost materials, and the part such as eedle presser, hollow deckle board can then be adopted Made of the material of lower cost.The utility model is designed reasonably, simple in structure, low manufacture cost, assembly and disassembly are simple convenient, Easy to the maintenance and replacement of local parts.
Brief description of the drawings
The utility model is further elaborated in conjunction with attached drawing:
Fig. 1 is the structure diagram of the utility model wiring board die cutting die.
Embodiment
As shown in Figure 1, the utility model wiring board die cutting die, it includes upper mold seat 1, upper mold 2, lower die 3 and die holder 4, the upper mold 2 drives lifting by upper mold seat 1, and the lower die 3 is arranged on the lower section of upper mold 2, leads between the lower die 3 and upper mold 2 Cross several leads 5 to connect, the upper mold 2 includes eedle presser 21, red needle plate 22 and several punchings for being punched wiring board 6 Pin 23, several described red needles 23 are separately mounted on red needle plate 22, and it is convex that 22 both sides of red needle plate are convexly equipped with a slip respectively Ear 24,21 lower surface of eedle presser offer the track runner 25 being adapted with 22 shape of cross section of red needle plate, the slip Lug 24 is slidably connected with track runner 25, and 21 upper surface of eedle presser is fixedly connected with upper mold seat 1;The lower die 3 includes Lower mold core 31 and the hollow deckle board 32 being adapted with 31 peripheral shape of lower mold core, 31 lower end of lower mold core are fixed on die holder 4 upper surface middle parts, the hollow deckle board 32 are movably set in outside lower mold core 31, and hollow 32 lower surface of deckle board passes through several Support spring 33 is liftable to be supported on 4 upper surface of die holder.
Preferably, several described leads 5 are respectively sleeved in several support springs 33, several described guiding 5 lower end of column is each attached to 4 upper surface of die holder, several described 5 upper ends of lead are threaded through hollow deckle board 32 and are equipped with respectively Several through holes(Do not marked in figure)In, and several the 26 corresponding grafting of pilot hole being equipped with 21 lower surface of eedle presser.Should Design can not only improve 33 compression anti-deformation ability of support spring, but also in hollow deckle board 32 2 punching press of upper mold can be subject to make With during causing it to decline and hollow deckle board 32 is supported 33 reset response of spring and causes it to play and lead during rising To effect, guiding role can also be played during upper mold 2 is lifted with away from or close to lower die 3.
Further, it is respectively provided with outside several described support springs 33 and limits some of hollow 32 falling head of deckle board A stop collar 34, several described 34 lower ends of stop collar are installed in 4 upper surface of die holder, several 34 upper surfaces of stop collar are equal Set with hollow 32 following table interplanar distance of deckle board.The design can not only limit hollow 32 falling head of deckle board, but also can be to branch Support spring 33 plays protective action.
