Abstract

The utility model provides a drop guide structure, which is adequate for a die. The die comprises an upper die part and a lower die part, wherein, the upper die part and the lower die part are relatively arranged and can be separated and closed; a drift plug is fixed at the upper die part; the lower die part is provided with a blanking hole opposite to the drift plug, and comprises a lower die seat; the lower die seat is provided with the drop guide structure; the drop guide structure mainly comprises a containing trough, a fixing seat and a fixing piece, wherein, the containing trough is opened on the lower die seat; the fixing seat is arranged in the containing trough, and is provided with a through hole; the fixing piece is arranged in the through hole; a clearance is arranged between the fixing piece and the fixing seat, and the blanking hole runs through the fixing piece and the lower die seat in sequence; the lower die seat is provided with a gas hole communicated with the clearance. By blowing gas to the gas hole, the drop guide structure uses self-gravity of scrap and suction generated by the blowing gas to discharge the scrap to the bottom of the blanking hole and avoids breaking the drift plug when punching.

Description

The guide structure

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of guide structure of mould.

Background technology

As shown in Figure 1, be the punching and blanking mould structure schematic diagram of prior art.Wherein, described mould structure mainly comprises a part of the upper die 10 and a counterdie part 20, and this part of the upper die 10 is provided with a drift 101, and this part of the lower die 20 is provided with a material-dropping hole 201, after the punching moulding, waste material relies on self gravitation to fall in the corresponding material-dropping hole.

Aforesaid way treats that owing to major part the product material of punching is lighter, and because the sucking-off of template magnetic waste material occurs and jumps out, weighs product wounded, causes product rejection.And when oil entered material-dropping hole 201, waste material was bonded at blanking hole wall side by oil easily, can't drop, and caused material-dropping hole to stop up, and during punching, easily drift 101 was interrupted once more.

Summary of the invention

In view of the above problems, the utility model provides a kind of guide structure, and it is applicable in the diel.

In order to achieve the above object, the utility model has adopted following technical scheme: a kind of guide structure, it is applicable in the mould, but part of the upper die that this mould has and part of the lower die are oppositely arranged and folding, and this part of the upper die is fixed with a drift, and this part of the lower die is provided with a material-dropping hole relative with this drift, and this part of the lower die comprises a die shoe, this die shoe is provided with a guide structure, and this structure mainly comprises a storage tank, and it is opened on this die shoe; One holder, it is positioned in this storage tank, and this holder is provided with a through hole; And a fixture, it is positioned in the above-mentioned through hole, and a gap is arranged between described fixture and the holder, and above-mentioned material-dropping hole runs through this fixture and die shoe in turn, and described die shoe is provided with a gas hole, and this gas hole communicates with above-mentioned gap.

Preferable, the utility model provides a kind of guide structure, and wherein, described through hole is infundibulate, and the one end is wide portion, and the other end is reduced into narrow portion gradually.

Compared to prior art, guide structure described in the utility model, it is by blowing in gas hole, and the suction that utilizes the waste material self gravitation and blow and produce drains into the material-dropping hole bottom with waste material, avoids the drift that fractures when punching.

The specific embodiment

Please refer to shown in Figure 2ly, be the utility model cutaway view.Guide structure described in the utility model is applicable to mainly in the mould that this mould has a part of the upper die 30 and a counterdie part 40.

Wherein, described part of the upper die 30 is fixed with a drift 301.

In addition, but described part of the lower die 40 is oppositely arranged and folding with this part of the upper die 30, this part of the lower die 40 is provided with a material-dropping hole 402 that runs through wherein, and this material-dropping hole 402 is relative with this drift 301, again, this part of the lower die 40 comprises a die shoe 401, offer a storage tank 4013 on this die shoe 401, be placed with a holder 4011 in this storage tank 4013, and this holder 4011 is provided with a through hole 40111, this through hole 40111 is set to wide end near an end of part of the upper die, and its other end is set to narrow end, to form an inclined-plane, correspondence is placed with a fixture 4012 in this through hole 40111, this fixture 4012 is funnel type, and itself and this through hole 40111 cooperatively interacts, and above-mentioned material-dropping hole 402 runs through this fixture 4012 in turn, this die shoe 401, and be reserved with a gap between this fixture 4012 and this holder 4011, in addition, also be provided with a gas hole 4013 on this die shoe 401, this gas hole 4013 is interconnected with above-mentioned gap.

After the punching press action is finished, utilize outside air blast that air communication is crossed above-mentioned gas hole 4013 and enter gap between this fixture 4012 and this holder 4011, because air-flow carries over the inclined-plane of through hole 40111 and enters, the waste material that produces in the punching course is inhaled downwards, and, thereby discharge because the gravity of waste material self makes waste material fall into this material-dropping hole 402 bottoms.

Claims

1. guide structure, it is applicable in the mould, but this mould has and is oppositely arranged and the part of the upper die and the part of the lower die of folding, this part of the upper die is fixed with a drift, this part of the lower die is provided with a material-dropping hole relative with this drift, and this part of the lower die comprises a die shoe, it is characterized in that, this die shoe is provided with a guide structure, and this structure mainly comprises:
