Abstract
The invention provides an air outlet hole structure of a die, the air outlet hole structure of the die is formed by combining two sections of holes, the direction of an opening of an air outlet hole of the die faces to the direction of a die mouth of the die, namely the direction of the opening of the air outlet hole is adjusted to be upward, and an air outlet slot is formed in the position of the air outlet hole of the die. The air outlet hole is divided into the two sections of the holes, thereby increasing the air outlet area, adjusting the air outlet direction, achieving the best air outlet effect and becoming a simple and practical die structure. The direction of the opening of the air outlet hole is upward, thereby reducing the probability of blocking the air outlet hole; on the other hand, the air outlet hole is made into the two sections of the air outlet holes, thereby increasing the diameter of the air outlet hole, increasing the air outlet area and enabling the air outlet effect to be better; and simultaneously, a large step can directly perform drilling processing during processing, compared with the processing by using electricity, the time is shorter and the cost is lower.
Description
Technical field
The present invention relates to material Plastic Forming and mould manufacturing field, particularly a kind of mould venthole structure.
Background technology
In material forming, a lot of moulds all need be left pore, but existing venthole structure all is whole venthole; And mould venthole direction all is towards mould below or the mould side, and venthole is the working region of mould, for avoiding because cumulative stress causes the mould fatigue failure; The diameter of venthole should be as far as possible little; And the venthole of traditional minor diameter exists the area of giving vent to anger little, very easily stopped up at work and the influence effect of giving vent to anger by foul, this structure exist venthole give vent to anger smooth with use a period of time posterior spiracle to be prone to blocked problem; The venthole deleterious of giving vent to anger; And venthole is prone to leave a trace at surface of the work when forging and molding, makes die manufacture complicated, and cost is higher.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of mould venthole structure is provided to the problem that exists in the above-mentioned prior art; Can increase the area of giving vent to anger, improve the effect of giving vent to anger of mould venthole, the compressed air when forging is discharged smoothly; And on surface of the work, can not stay the vestige of venthole during forging and molding yet; Eliminate the vestige that venthole stays at surface of the work when forging and molding, made the mould manufacturing more simple and convenient, reduced cost.
For solving the problems of the technologies described above, the invention provides following technical scheme: a kind of mould venthole structure, the structure of said mould venthole is combined by two sector holes.
As a kind of preferred version of mould venthole structure according to the invention, the opening direction of wherein said mould venthole upwards.
As a kind of preferred version of mould venthole structure according to the invention, wherein leave air drain in said mould venthole position.
As a kind of preferred version of mould venthole structure according to the invention, in two sector holes of said composition mould venthole, the aperture of inboard aperture is less than the aperture of apertura lateralis
The invention has the beneficial effects as follows: the present invention is adjusted into the opening direction of venthole upwards, i.e. die orifice direction, and venthole is divided into two sections ventholes, foul generally all is to pile up at the downside of mould in the course of the work on the one hand;, reduce the probability that venthole stops up with the venthole opening direction up, on the other hand, venthole has been made two sections ventholes; Increased the venthole diameter, the area of giving vent to anger increases, the better effects if of giving vent to anger; Simultaneously, adding man-hour, the processing of can directly holing of big step; Than comparing with electric machining, the time is shorter, and cost is lower.The venthole of this structure has increased the area of giving vent to anger of venthole when forging and molding, the compressed air of generation can be discharged smoothly; In addition, because the opening direction of giving vent to anger upwards, during forging and molding; Material is difficult for flowing to venthole, after the demoulding, pore just can residual to the material of pore; When forging, just can not stay the venthole vestige on the forging surface like this, improve the surface quality of forging.
Description of drawings
Accompanying drawing 1 is a mould venthole structural profile sketch map according to the invention.
Accompanying drawing 2 is mould venthole structure vertical view sketch mapes according to the invention.
Accompanying drawing 3 is partial enlarged drawings of I part shown in Figure 1.
Wherein, 1, mould venthole; 2, another section die venthole; 3, outgassing groove.
The specific embodiment
Below in conjunction with accompanying drawing and practical example the present invention is described further.
Like accompanying drawing 1; A kind of mould venthole structure, the structure of said mould venthole is combined by 1,2 liang of sector hole, and the opening direction of said mould venthole is towards said die orifice direction; Just the opening direction with venthole is adjusted into upwards, and air drain is left in said mould venthole position.
Structure is designed to shown in accompanying drawing, and 1,2 is the venthole system, on mould, makes a call to the deep hole of a φ 3 earlier according to size, uses punch after the quenching again, and along the hole that miter angle is worn a φ 1, and the gas groove is left in 3 positions in punch position such as accompanying drawing 2.
The venthole of this structure has increased the area of giving vent to anger of venthole when forging and molding, the compressed air of generation can be discharged smoothly; In addition, because the opening direction of giving vent to anger upwards, during forging and molding; Material is difficult for flowing to venthole, after the demoulding, pore just can residual to the material of pore; When forging, just can not stay the venthole vestige on the forging surface like this, improve the surface quality of forging.
What should explain is; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the spirit and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
Claims (4)
1. the structure of a mould venthole, it is characterized in that: the structure of said mould venthole is combined by two sector holes.
2. mould venthole structure according to claim 1 is characterized in that: the opening direction of said mould venthole upwards.
3. mould venthole structure according to claim 1 is characterized in that: said mould venthole position sets out air drain.
