Abstract
The invention discloses anti-scrap bouncing structure in a kind of mould.The present invention includes concave template, die holder plate and support block, and described die holder plate is supported by support block, and multiple waste discharge holes are carried on die holder plate, and waste discharge hole exits are located between support block, and described concave template is located on die holder plate, corresponding with die holder plate.The passage and the passage of concave template that die holder plate, concave template directly over support block side are provided with passage, die holder plate are coaxially disposed, and the ventilation bore dia on die holder plate is more than the ventilation bore dia of concave template；The passage lower end of die holder plate passes through the space UNICOM between the scarf and support block on support block.The structure can cause space pressurize between support block, so that avoiding the fragment of punching from producing jumps bits phenomenon, yield rate is improved, and reduces production cost.
Description
Technical field
The invention belongs to Stamping Die Technology field, it is related to anti-scrap bouncing structure in a kind of mould.
Background technology
Diel is the technological equipment that material is processed into part or semi-finished product in Cold Press Working, in punching press
Cheng Zhong, the fragment of punching is normally between support block.But because dies holder and concave template quick detachable can produce negative pressure, so that
The fragment of punching is caused to produce the behavior of bounce, thereby the fragment of the punching can return to product surface by slug hole, so
Can cause to weigh wounded to product or burn failure phenomenon, both wasted the cost of material, the efficiency of work reduced again.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides anti-scrap bouncing structure in a kind of mould.
The technical solution adopted in the present invention is：
The present invention includes concave template, die holder plate and support block, and described die holder plate is supported by support block, with multiple on die holder plate
Waste discharge hole, waste discharge hole exits are located between support block, and described concave template is located on die holder plate, corresponding with die holder plate, in support block side
The passage and the passage of concave template that die holder plate, concave template directly over side are provided with passage, die holder plate are coaxially disposed, and
Ventilation bore dia on die holder plate is more than the ventilation bore dia of concave template；The passage lower end of die holder plate passes through the transition on support block
Space UNICOM between section and support block.
Furtherly, described changeover portion is inclined-plane or cambered surface.
The invention has the advantages that：The structure can cause space pressurize between support block, so as to avoid the broken of punching
Piece, which is produced, jumps bits phenomenon, and yield rate is improved, and reduces production cost.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in figure 1, the present embodiment concave template 2, die holder plate 3 and support block 4, die holder plate are supported by support block, band on die holder plate
There are multiple waste discharge holes（One is only gived in the present embodiment）, waste discharge hole exits are between support block, and concave template is located at die holder plate
On, it is corresponding with die holder plate.Die holder plate, concave template directly over support block side be provided with passage on passage 1, die holder plate with
The passage of concave template is coaxial, and the ventilation bore dia on die holder plate is more than the ventilation bore dia of concave template；The ventilation of die holder plate
Hole lower end passes through the space UNICOM between the scarf and support block on support block.
In punching course, concave template is brought into close contact with die holder plate, and its inside is placed with product to be formed, due to cavity plate
During plate gos up, its moment can produce a negative pressure in die holder plate, the presence of the negative pressure can cause the waste material 5 that is punched by
Slug hole is back to product surface, and utilizes this structure, can eliminate the negative pressure, so that waste material will not occur to jump bits action, it is ensured that
The yield rate of product.
