Abstract
The utility model discloses a venting plug for a grinding ball casting mould venting hole, which comprises a prism-shaped main body, wherein the section of the prism-shaped main body is a square, and the front end of the prism-shaped main body is provided with a cone frustum shaped structure. The venting plug provided by the utility model has the advantages of more reasonable structure, convenience for manufacturing, simpleness in installation, easy replacement and no air resistance; and poor casting is not caused or an invasion air pore is not generated.
Description
Technical field
The utility model relates to a kind of abrading-ball mold steam vent and uses venting plug.
Background technology
Abrading-ball in the ball mill that industries such as metallurgy, mine, building materials, steam power plant are used is cast with metal type dies mostly and is formed; The metal type dies that prior art is produced is used to stop up the venting plug of mould upper air-vent, is to add waterglass by asbestos cord and quartz sand to process mostly; Result of use is not ideal; Because the venting plug design is unreasonable, causes the venting plug processing difficulties, production cost is increased; Secondly, can cause exhaust not smooth, produce defectives such as runout, the fire of choking with quartz sand and waterglass; Once more, because the shape of venting plug science not, make and excesssive gap between venting plug and the steam vent cause molten metal to overflow; Not only cause waste, reduce the utilization rate of molten metal, and quickened damage; Increase die manufacturing cost, in addition, used asbestos cord to stop up; Need often to change venting plug, both labor intensive, material resources, time, also influence production efficiency.
Summary of the invention
The technical problem that the utility model solves is, provides a kind of abrading-ball mold steam vent use venting plug, and structure is more reasonable, easily manufactured, it is simple to install, it is easy to change.
The technical scheme that the utility model adopts is:
A kind of abrading-ball mold steam vent is used venting plug, comprises prismatic body, and the cross section of prismatic body is a square, and the front end of prismatic body is the truncated cone structure.
The utility model relies on four corner angle of venting plug to realize interference fit with steam vent in use, realizes fixing of venting plug, and the interstitial row through prismatic body and steam vent goes out the gas in the mold cavity, hinders overflowing of molten metal again; This venting plug is in mold cavity, to be pressed into the steam vent of mold cavity, and makes it rivet clasp, and the air pressure that produces when preventing to cast ejects venting plug; Thereby prevent overflowing of molten metal effectively; Help the discharge of gas, and then also protected mould, prolong its service life; Also can avoid simultaneously the waste of molten metal, increase operation rate.
The beneficial effect of the utility model is:
1, be easy to processing, make simply, easy for installation, change easily, improved business efficiency.
2, venting quality is good: the gas that the gas during casting in the die cavity, core and coating produce is discharged through the gap between venting plug and the steam vent apace, can not form vapour lock, causes poured short or produces and invade pore.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Embodiment:
Shown in accompanying drawing, a kind of abrading-ball mold steam vent is used venting plug, comprises prismatic body 1, and the cross section of prismatic body 1 is a square, and the front end of prismatic body 1 is a truncated cone structure 2.
The utility model relies on four corner angle of venting plug to realize interference fit with steam vent in use, realizes fixing of venting plug, and the interstitial row through prismatic body and steam vent goes out the gas in the mold cavity, hinders overflowing of molten metal again; This venting plug is in mold cavity, to be pressed into the steam vent of mold cavity, and makes it rivet clasp, and the air pressure that produces when preventing to cast ejects venting plug.
