Description

The lower die of wiring board die cutting die

Technical field

It the utility model is related to die cutting die technical field, more particularly to the lower die of wiring board die cutting die.

Background technology

Existing wiring board die cutting die generally all includes upper mold seat, upper die and lower die and die holder, and the upper mold is arranged on Upper mold seat lower surface, and driven and lifted by upper mold seat, the lower die is arranged on below upper mold, and is arranged on die holder upper surface； Wherein, lower die has the lower mold core for being used for mold center position as crucial running precision component.Existing lower die is typically one Body formula structure, as being designed with material-dropping hole greatly in the lower mold core of die core, which is typically caliber size from top to bottom It is identical, so as to cause blanking easily to block material-dropping hole, once blanking is stuck in material-dropping hole, it gently can not then continue punching and make For industry, it is necessary to can just work on after clearing up, time-consuming trouble, influence efficiency, service life that is heavy then influencing mould, or even directly causes Its corrupted is scrapped, but can not relatively be used on the method or structure of cleaning blanking in the prior art；In addition, existing treat Punching wiring board side would generally be reserved with remaining side, which can fall after punching in lower mold core side, not disposable.

The content of the invention

The purpose of this utility model is that in view of the deficiencies of the prior art, there is provided one kind design is reasonable, simple in structure, makes Cost is low, the lower die of the simple efficiently wiring board die cutting die of blanking cleaning.

To achieve the above object, the utility model uses following technical scheme：

The lower die of wiring board die cutting die, it includes lower mold core and end template, and the lower mold core lower end is fixed on end template Upper surface, the lower mold core are equipped with several material-dropping holes, and material-dropping hole is corresponded on the end template and is equipped with the blanking hole being adapted, It further includes the hollow deckle board being adapted with lower mold core peripheral shape, and the hollow deckle board is liftable to be set in outside lower mold core, The end template following table interplanar distance is equipped with multiple support beams, is correspondingly provided with and inclines on the opposite two side of two neighboring support beam Two track grooves tiltedly set, are plugged with described two track grooves for accepting and the reclaiming plate of conveying and blanking.

Preferably, the hollow deckle board lower surface is supported on end template upper table by the way that several support springs are liftable Face.The design of the support spring so that hollow deckle board can play a supporting role after by drops, and be utilized after external force is removed Its spring force, which jacks up hollow deckle board, to be risen to reset.

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 end template 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, several described stop collar lower ends are threaded in end template upper surface respectively.The design makes it can The distance between stop collar upper surface and hollow deckle board lower surface are adjusted to be connected through a screw thread, so as to control under hollow deckle board Drop height, and then adjust the height that lower mold core upper surface is higher by hollow deckle board upper surface.

Further, the reclaiming plate insertion end is equipped with the fixed hook for preventing that reclaiming plate from sliding.

Further, it is equipped with the higher one end of the track groove and hooks groove, the fixed hook is hooked to put and hooked in groove.

Preferably, the angle of inclination of the track groove is more than 30 °.The design can utilize blanking on reclaiming plate smoothly to slide Fall.

Preferably, the material-dropping hole is gradually expanded from lower mold core upper end to lower mold core lower end.

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.

Preferably, after the hollow deckle board rises, lower mold core upper surface and hollow deckle board upper surface flush.

The utility model uses above technical scheme, and the design of hollow deckle board and lower mold core can be in hollow deckle board Punch surface is cooperatively formed during decline with lower mold core to be used to be punched side more than wiring board side, and after the rising of hollow deckle board, lower die Core upper surface and hollow deckle board upper surface flush, can jack up the remaining side after punching to clear up, so as to instead of tradition one The lower die of body formula structure, can distinguish the parts such as centering empty frames plate and lower mold core and carry out local replacing, and can use Material of low cost makes hollow deckle board, so as to reduce cost；The design of multiple support beams, not only can be to avoid blanking Blanking hole is blocked, and causes blanking hole lower end to be blocked after being installed to avoid end template, while can also be in end template Play support and booster action in portion；The design of reclaiming plate, can accept the blanking to drop from blanking hole, and inclining using reclaiming plate Tiltedly set so that blanking is slid out to clear up below end template under its own gravity along reclaiming plate length direction, effectively Prevent blanking clogging.The utility model is designed reasonably, simple in structure, low manufacture cost, cleaning blanking is convenient and efficient, Blanking blocking can effectively be prevented.
