Abstract
The utility model discloses a kind of mo(u)lding line venting machine air-out needle, it comprises pricks gas plate, and be fixed on the air-out needle pricked on gas plate by nut, described air-out needle is provided with a cylindrical base, and described cylindrical base lower surface contacts with bundle gas plate upper surface; The diameter of described cylindrical base is the twice of air-out needle diameter.It is simple that the utility model has structure, and good looking appearance, enhances productivity, and reduces the advantage of unit casting cost.
Description
Technical field
The utility model relates to a kind of air-out needle, is specifically related to a kind of mo(u)lding line venting machine air-out needle.
Background technology
In the professional foundry production of large-scale, venting machine air-out needle and productivity ratio have direct relation.Fig. 1 is prior art air-out needle structure chart, by two nuts 3
,by air-out needle 1
,be fixed on and prick gas plate 2
,on, air-out needle carries out processing and fabricating, modified rear hardness 30-35HBS after adopting the modifier treatment of 45# steel, requires that hardness must not higher than 33HBS in production process, hardness too high abrasion but not easily process, and easily produces fracture in process of production.Because air-out needle nut is little with the contact area of pricking gas plate, air-out needle force localization in the operation of rolling causes air-out needle to occur fracture through nut upper surface of being everlasting, and changing air-out needle affects rhythm of production and production efficiency.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, reduces the frequency of venting pin fracture in production process, enhance productivity, reduce a kind of mo(u)lding line venting machine air-out needle of unit casting cost.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of mo(u)lding line venting machine air-out needle, it comprises pricks gas plate, and be fixed on the air-out needle pricked on gas plate by nut, described air-out needle is provided with a cylindrical base, and described cylindrical base lower surface contacts with bundle gas plate upper surface.
The diameter of described cylindrical base is the twice of air-out needle diameter.
The beneficial effects of the utility model are: the utility model structure is simple, column type base adds air-out needle and the contact area of pricking gas plate, disperse active force, the frequency that air-out needle is ruptured significantly declines, and the number of times of air-out needle fracture reduces, and production efficiency is improved, the waste of water, electricity, gas is controlled, air-out needle makes material and is controlled and reduce, and unit casting cost reduces, for company creates economic benefit.
Accompanying drawing explanation
Fig. 1 prior art structural representation;
Fig. 2 is the utility model structural representation.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As described in Figure 2, a kind of mo(u)lding line venting machine air-out needle, it comprises pricks gas plate 2, and be fixed on the air-out needle 1 pricked on gas plate 2 by nut 3, air-out needle 1 is provided with a cylindrical base 4, and cylindrical base 4 lower surface contacts with bundle gas plate 2 upper surface.
The diameter of cylindrical base 4 is the twice of air-out needle 1 diameter.
The contact surface that cylindrical base 4 adds air-out needle 1 and bundle gas plate 2 connects, and active force is disperseed, reduces pressure, thus make air-out needle 1 not easy fracture, reduce replacement frequency, reduce production cost.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. a mo(u)lding line venting machine air-out needle, it comprises pricks gas plate, is fixed on the air-out needle pricked on gas plate, it is characterized in that: described air-out needle is provided with a cylindrical base by nut, and described cylindrical base lower surface contacts with bundle gas plate upper surface.
2. a kind of mo(u)lding line venting machine air-out needle according to claim 1, is characterized in that: the diameter of described cylindrical base is the twice of air-out needle diameter.
