Abstract
The invention discloses a die casting mould, which comprises an upper mould unit and a lower mould unit. An upper mould cavity unit is arranged on the upper mould unit; a lower mould cavity unit is arranged on the lower mould unit; the upper mould cavity unit is matched with the lower mould cavity unit to form a die casting space; a feeding port is arranged on the upper portion of the die casting space; a feeding channel is communicated with the feeding port; and an air hole is arranged on the die casting space and communicated with the feeding channel. Rapid forming is facilitated by the aid of the gravity and the pressure of filled liquor, and air in the die casting space is conveniently exhausted when the die casting space is pressurized as the air hole is arranged on the die casting space. Therefore, a portion D at the long and thin tail end of the die casting space can be properly formed, so that forming quality is ensured.
Description
Technical field
The present invention relates to a kind of die casting, refer in particular to the good die casting of a kind of forming effect, belong to the die casting technical field.
Background technology
Compression casting belongs to hot forming metal manufacture field; The structural design of die casting is bigger to die casting production influence; Particularly the correct setting of running channel and cast gate directly influences the shaping of product and the quality of product with design; The design of correct mould structure and die casting running channel not only improves the qualification rate of foundry goods, reduces foundry returns, can also prolong the life-span of mould.Present die cast product is got over to large-scale, complicacy, accurate development; This just proposes higher requirement to the structural design of die casting and runner and cast gate design, often is because the design of mould structure and die casting running channel is provided with incorrectly sometimes, causes foundry goods to be shaped and shaping fraction defective extra-high-speed; In the time can not passing through other die casting parametric compensation; Have to be with the die casting condition of the limit, extrusion process removes bad influence with other numerous processing technology of increase, and it still is undesirable having increased many man power and material's effects often; The mould premature failure, the die casting cost increases; The die casting of the prior art shown in accompanying drawing 1 includes a mold unit 1, and once die unit 2, forms the lower mode cavity unit 4 of upper cavity unit 3, the one formation cavitys of cavity, feeding-passage 7 and charging aperture 8; Said upper cavity unit 3 and lower mode cavity unit 4 are combined to form the space 6 of die casting; Said charging aperture 8 is arranged on the sidepiece in the space 6 of die casting; Said feeding-passage 7 is connected with charging aperture 8; During casting forming, liquid material sealing foundry goods D portion 9, formation can't be discharged the cavity space of gas, and tiny muscle position D portion 9 is shaped and can only fills with the pressure current form, causes the forming effect of die casting bad.
Summary of the invention
The present invention seeks to provides a kind of forming effect good die casting for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of die casting comprises mold unit, bed die unit; Said mold unit is provided with unit, a patrix shape chamber; Said bed die unit is provided with unit, a counterdie shape chamber; Unit, said patrix shape chamber matches with unit, counterdie shape chamber and forms the space of a die casting; Said charging aperture is arranged on the top in the space of die casting; Said feeding-passage is connected with charging aperture; The space of said die casting is provided with pore, and said pore is communicated with feeding-passage.
Beneficial effect of the present invention is mainly reflected in: die casting of the present invention, charging aperture are arranged on the top in the space of die casting; Utilize the gravity and the pressure of filling solution to help quick shaping; Simultaneously, on the space of die casting, be provided with pore, convenient when pressurizeed in the space of die casting; The discharge of the air in it; To the D portion of the elongate tip in the space of die casting, being shaped also can put in place, thereby has guaranteed forming quality like this.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the cutaway view of the described die casting of prior art;
Accompanying drawing 2 is the cutaway view of die casting of the present invention;
Wherein: 1, mold unit; 2, bed die unit; 3, upper cavity unit; 4, lower mode cavity unit; 6, the space of die casting; 7, feeding-passage; 8, charging aperture; 9, D portion; 10, mold unit; 20, bed die unit; 30, upper cavity unit; 40, lower mode cavity unit; 50, pore; 60, the space of die casting; 70, feeding-passage; 80, charging aperture; 90, D portion.
The specific embodiment
Of the present invention a kind of die casting shown in accompanying drawing 2 comprises mold unit 10, bed die unit 20; Said mold unit 10 is provided with unit, a patrix shape chamber 30; Said bed die unit 20 is provided with unit, a counterdie shape chamber 40; Unit, said patrix shape chamber 30 matches with unit, counterdie shape chamber 40 and forms the space 60 of a die casting; Said charging aperture 80 is arranged on the top in the space 60 of die casting; Said feeding-passage 70 is connected with charging aperture 80; The space 60 of said die casting is provided with pore 50, and said pore 50 is communicated with feeding-passage 70.
Die casting of the present invention, charging aperture are arranged on the top in the space of die casting; Utilize the gravity and the pressure of filling solution to help quick shaping; Simultaneously, on the space of die casting, be provided with pore, convenient when pressurizeed in the space of die casting; The discharge of the air in it; To the D portion of the elongate tip in the space of die casting, being shaped also can put in place, thereby has guaranteed forming quality like this.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
