Description
Technical field
The utility model relates to mould, particularly relates to the mould being provided with air bleeding valve.
Background technology
When carrying out die casting workpiece, usual liquid of casting imports in mold cavity, owing to being originally filled with air in mold cavity, being therefore generally provided with in a mold and ranked first pore, but easily flow into after casting liquid enters mold cavity and ranked first in pore, thus cause the blocking that ranked first pore.For solving this problem, usually Design of Dies is become the air bleeding valve without the first pore, existing nothing first pore air bleeding valve is usually by the tapered faying face of Front-end Design of valve pocket and spool, this taper faying face is utilized to form exhaust clearance, for ensureing that this exhaust clearance is closed at the end of opening exhaust in exhaust process, usually in air bleeding valve, spring is provided with, the compression of spring and stretching is utilized to realize the open and close of exhaust clearance, in long-term use procedure, the inefficacy that there will be due to spring causes exhaust clearance not open and close normally, thus cause Forming Quality to reduce.In addition, existing nothing first pore die venting valve in use, remains in the space of spool and valve pocket owing to having a small amount of casting liquid, causes and can not fit completely at exhaust end back valve core and valve pocket, thus cause with pit on finished workpart, not only unsightly but also be difficult to repair.
Summary of the invention
The shortcoming that the utility model has some setbacks for the volatile effect of spring in prior art, exhaust, provides the mould being provided with air bleeding valve.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The mould of air bleeding valve is installed, comprise mould and be located at the steam vent on mould, in steam vent, valve pocket is installed, in valve pocket, spool is installed, spool is hollow structure, the upper end of valve pocket is provided with taper enlarging, spool is provided with the conical surface coordinated with taper enlarging, the conical surface is provided with the first pore, the bottom of spool is provided with the second pore, the outer surface of spool is provided with bulge loop, and valve pocket is provided with the first buckling groove and the second buckling groove that all coordinate with bulge loop, and the first buckling groove and the second buckling groove are setting up and down and control the position of spool in valve pocket along valve sleeving inner wall.Spool design is become hollow structure and to be provided with on spool in connecting mold die cavity and pore outside mold cavity, be fastened on different buckling grooves by bulge loop and control the position of spool in valve pocket, working stability is reliable; In addition, air bleeding valve of the present utility model also has good exhaust effect, easily manufactures, convenient disassembly, is convenient to cleaning, prevents die casting liquid from remaining in advantage in the space of spool and valve pocket.
First pore is slotted hole, and the first pore has one at least, and the first pore is evenly arranged on the conical surface.Equally distributed first pore makes exhaust better smooth and easy.
The quantity of the first pore is four.
Second pore is located at the center position of spool bottom surface, and the diameter dimension of the second pore is 1/3 ~ 1/5 of spool bottom surface diameter dimension.To the size design of the second pore, make it coordinate the air mass flow of the first pore, make exhaust better smooth and easy.
Angle between the conical surface and valve core axis is 30 °-45 °.
The utility model is owing to have employed above technical scheme, there is significant technique effect: spool design is become hollow structure and on spool, is provided with the pore be communicated with in mold cavity and outside mold cavity by the utility model, be fastened on different buckling grooves by bulge loop and control the position of spool in valve pocket, working stability is reliable; In addition, also there is good exhaust effect, easily manufactures, convenient disassembly, be convenient to cleaning, prevent die casting liquid from remaining in advantage in the space of spool and valve pocket.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Embodiment 1
The mould of air bleeding valve is housed, as shown in the figure, comprise mould and be located at the steam vent 1 on mould, valve pocket 2 is installed in steam vent 1, spool 3 is installed in valve pocket 2, spool 3 is hollow structure, the upper end of valve pocket 2 is provided with taper enlarging 21, spool 3 is provided with the conical surface 31 coordinated with taper enlarging 21, the conical surface 31 is provided with the first pore 311, the bottom of spool 3 is provided with the second pore 32, first pore 311 is all communicated with the hollow cavity of spool 3 with the second pore 32, the air inside and outside mold cavity is communicated with the second pore 32 by the first pore 311 on spool 3, the outer surface of spool 3 is provided with bulge loop 33, valve pocket 2 is provided with the first buckling groove 22 and the second buckling groove 23 all coordinated with bulge loop 33, first buckling groove 22 is positioned at the upper end of the second buckling groove 23, first buckling groove 22 and the second buckling groove 23 are setting up and down and control the position of spool 3 in valve pocket 2 along valve pocket 2 inwall.When carrying out die casting by mould, bulge loop 33 on spool 3 is fastened on the first buckling groove 22, spool 3 is raised up, now there is gap between the conical surface 31 and taper enlarging 21, die casting liquid is injected in mould, air pressure in mould strengthens, gas by the first pore 311 on the conical surface 31 enter spool 3 hollow structure in and discharge outside mold cavity by the second pore 32; After die casting liquid fills full mold cavity, because spool 3 promotes downwards by the pressure of die casting liquid, make bulge loop 33 depart from the first buckling groove 22 and fasten the second buckling groove 23 below the first buckling groove 22, the conical surface 31 is now fitted with taper enlarging 21, effectively prevents the die casting liquid in mould from discharging outside mould along air bleeding valve.First pore 311 is slotted hole, and the quantity of the first pore 311 is four, and the first pore 311 is evenly arranged on the conical surface 31, and the first pore 311 is located on the conical surface 31 of spool 3 upper surface.Second pore 32 is located at the center position of spool 3 bottom surface, and the diameter dimension of the second pore 32 is 1/4 of spool 3 bottom surface diameter dimension.Angle between the conical surface 31 and spool 2 axis is 40 °.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
