Abstract
The utility model discloses a kind of novel die torn edges slot structure, including the upper die and lower die being engaged, the die cavity for formed product is provided between the upper die and lower die, torn edges groove is a pair, two torn edges grooves are separately positioned on the both sides of die cavity, the torn edges groove is arranged on mould and/or lower mould, and the torn edges groove is curved slot arrangement.The novel die torn edges slot structure is reasonable in design, and torn edges groove is because of rounded bottom surface, good fluidity, and without being deliberately pressurized, the place that is not available for waste material to gather, torn edges effect is good；No waste mine residual aggregation, upper and lower mould cooperation is closer, and torn edges is more smooth；And it is cost-effective, extend the mold use time limit.
Description
Technical field
Technical field of mold is the utility model is related to, more particularly, to a kind of novel die torn edges slot structure.
Background technology
Existing mould torn edges groove is all triangle, and triangle sizing material flow velocity is slow, need to increase sizing material, reaches supercharging, is increased
Big flow velocity.Mould uses for a long time, has dead glue, scrap rubber remains in the sharp corner of torn edges groove, hardly possible cleaning；Sharp corner waste material collection
Poly-, causing upper and lower mould to coordinate can not be close, influences torn edges effect, overlap and flash defect be present.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved in the utility model is to provide a kind of novel die torn edges groove
Structure, to reach the purpose that rubber mobility is good, and no waste mine is assembled.
In order to solve the above-mentioned technical problem, technical scheme is used by the utility model：
The novel die torn edges slot structure, including the upper die and lower die being engaged, it is provided between the upper die and lower die and uses
In the die cavity of formed product, torn edges groove is a pair, and two torn edges grooves are separately positioned on the both sides of die cavity, and the torn edges groove is arranged on
On mould and/or lower mould, the torn edges groove is curved slot arrangement.
Further, the torn edges groove is located on mould or lower mould, and torn edges groove is semi-circular groove.
Semicircular torn edges groove is equipped with the upper die and lower die at opposite position, two halves circle cooperatively forms circle
Shape.
The torn edges slot distance die cavity is 0.3-0.5mm.
It is waveform at upper die and lower die cooperation between die cavity and the torn edges groove.
The utility model compared with prior art, has advantages below：
The novel die torn edges slot structure is reasonable in design, and torn edges groove is because of rounded bottom surface, good fluidity, without being deliberately pressurized,
The place for not being available for waste material to gather, torn edges effect are good；No waste mine residual aggregation, upper and lower mould cooperation is closer, and torn edges is more smooth；
And it is cost-effective, extend the mold use time limit.
Brief description of the drawings
The content expressed by each width accompanying drawing of this specification and the mark in figure are briefly described below：
Fig. 1 is the utility model mould torn edges slot structure schematic diagram.
In figure：
Mould, 2. times moulds, 3. die cavitys, 4. torn edges grooves on 1..
Embodiment
Below against accompanying drawing, by the description to embodiment, specific embodiment of the present utility model is made further detailed
Thin explanation.
As shown in figure 1, the novel die torn edges slot structure, including the upper mould 1 being engaged and lower mould 2, upper mould 1 and lower mould 2
Between be provided with for formed product die cavity 3, torn edges groove 4 be a pair, two torn edges grooves are separately positioned on the both sides of die cavity.
The torn edges slot structure shape of the both sides of die cavity 3 is identical, simplifies structure, easily fabricated, reduces cost.Below to one
Side torn edges groove illustrates.
Torn edges groove 4 is arranged on mould and/or lower mould, and torn edges groove is curved slot arrangement.Preferably, torn edges groove is located at mould
Or on lower mould, torn edges groove is semi-circular groove；Or semicircular torn edges groove is equipped with upper die and lower die at opposite position,
Two halves circle cooperatively forms circle.
Torn edges groove is because of rounded bottom surface, good fluidity, without being deliberately pressurized, the place that is not available for waste material to gather, and torn edges effect
Fruit is good；No waste mine residual aggregation, upper and lower mould cooperation is closer, and torn edges is more smooth.
Torn edges slot distance die cavity is 0.3-0.5mm.It is waveform at upper die and lower die cooperation between die cavity and torn edges groove.
Torn edges effect is good, avoids producing overlap and flash.
Or upper die and lower die correspond to setting half elliptic groove at same position, the torn edges groove of two half elliptics coordinates
Form an ellipse.Same effect can be reached, torn edges groove lower arcuate surface, good fluidity, without being deliberately pressurized, be not available for
The place that waste material gathers, torn edges effect are good.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as employing the improvement of the various unsubstantialities of design of the present utility model and technical scheme progress,
Or it is not improved by it is of the present utility model design and technical scheme directly apply to other occasions, in guarantor of the present utility model
Within the scope of shield.
