Abstract
The utility model discloses a prevent jumping bits structure in mould. The utility model discloses a die board, die holder board and mould foot, the die holder board support by the mould foot, have a plurality of holes of wasting discharge on the die holder board, the hole export of wasting discharge lies in between the mould foot, the die board be located the die holder board, correspond with the die holder board. Die holder board directly over mould foot side, the die board is opened has the air vent, air vent and the coaxial setting of the air vent of die board on the die holder board, and the air vent diameter on the die holder board is greater than the air vent diameter of die board, the air vent lower extreme of die holder board passes through scarf and the space UNICOM between the mould foot on the mould foot. This structure can make space pressurize between the mould foot to the piece of avoiding the blanking produces jump bits phenomenon, and the yield improves, has reduced manufacturing cost.
Description
Technical field
The utility model belongs to Stamping Die Technology field, relates to anti-scrap bouncing structure in a kind of mould.
Background technology
Diel is in Cold Press Working, materials processing is become part or half-finished technological equipment, and in punching course, the fragment of stamping-out is generally between mould pin.But because dies holder and concave template quick detachable can produce negative pressure, thus cause the fragment of stamping-out to produce the behavior of beating, the fragment of this stamping-out can get back to product surface by slug hole by this, can cause to product like this and weigh wounded or the phenomenon of burn failure, both waste the cost of material, again reduce the efficiency of work.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides anti-scrap bouncing structure in a kind of mould.
The technical scheme that the utility model adopts is:
The utility model comprises concave template, die holder plate and mould pin, described die holder plate is supported by mould pin, with multiple waste discharge hole on die holder plate, waste discharge hole exits is between mould pin, described concave template is positioned on die holder plate, corresponding with die holder plate, and the die holder plate directly over mould pin side, concave template have passage, passage on die holder plate and the passage of concave template are coaxially arranged, and the passage diameter on die holder plate is greater than the passage diameter of concave template; The passage lower end of die holder plate is by the space UNICOM between the scarf on mould pin and mould pin.
The beneficial effect that the utility model has is: this structure can make space pressurize between mould pin, thus avoids the fragment of stamping-out to produce jumping bits phenomenon, and yield rate improves, and reduces production cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the present embodiment concave template 2, die holder plate 3 and mould pin 4, die holder plate is supported by mould pin, with multiple waste discharge hole (only giving one in the present embodiment) on die holder plate, waste discharge hole exits is between mould pin, and concave template is positioned on die holder plate, corresponding with die holder plate.Die holder plate directly over mould pin side, concave template have passage 1, and the passage on die holder plate is coaxial with the passage of concave template, and the passage diameter on die holder plate is greater than the passage diameter of concave template; The passage lower end of die holder plate is by the space UNICOM between the scarf on mould pin and mould pin.
In punching course, concave template and die holder plate fit tightly, product to be formed is placed with inside it, due in concave template rise process, it can produce a negative pressure instantaneously in die holder plate, and the existence of this negative pressure can cause the waste material 5 be punched to be back to product surface by slug hole, and utilize this structure, can eliminate this negative pressure, thus waste material can not occur to jump bits action, ensure that the yield rate of product.
Claims (1)
1. anti-scrap bouncing structure in a mould, comprise concave template, die holder plate and mould pin, described die holder plate is supported by mould pin, with multiple waste discharge hole on die holder plate, waste discharge hole exits is between mould pin, and described concave template is positioned on die holder plate, corresponding with die holder plate, it is characterized in that: the die holder plate directly over mould pin side, concave template have passage, the passage on die holder plate and the passage of concave template are coaxially arranged, and the passage diameter on die holder plate is greater than the passage diameter of concave template; The passage lower end of die holder plate is by the space UNICOM between the scarf on mould pin and mould pin.
