Abstract
The invention relates to an exhaust plug for an exhaust hole of a grinding ball casting mold. The exhaust plug comprises a prismatic main body, wherein the section of the prismatic main body is square, and a truncated cone-shaped structure is arranged at the front end of the prismatic main body. The exhaust plug disclosed by the invention has the advantages of being relatively reasonable in structure, convenient to manufacture, simple in mounting, easy to replace, free from air resistance so as to avoid the phenomena of insufficient casting or production of invasive air holes.
Description
Technical field
The present invention relates to a kind of venting plug for grinding ball casting mould venting hole.
Background technology
The large multiplex metal type dies casting of abrading-ball in the ball mill that the industries such as metallurgy, mine, building materials, steam power plant are used forms, the metal type dies that prior art is produced, be used for stopping up the venting plug of mould upper air-vent, to add waterglass by asbestos cord and quartz sand to make 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 with quartz sand and waterglass, produce the defectives such as the fire of running away, choke; Again, because the shape of venting plug science not, so that the 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 accelerated damage, increased die manufacturing cost, in addition, use asbestos cord to stop up, need often to change venting plug, both labor intensive, material resources, time, also affected production efficiency.
Summary of the invention
The technical problem that the present invention solves is, a kind of venting plug for grinding ball casting mould venting hole is provided, and structure is more reasonable, easily manufactured, it is simple to install, change easily.
The technical solution used in the present invention is:
A kind of venting plug for grinding ball casting mould venting hole comprises prismatic body, and the cross section of prismatic body is square, and the front end of prismatic body is the truncated cone structure.
The present invention relies on four corner angle of venting plug and steam vent to realize interference fit in use, realizes the fixing of venting plug, and the interstitial row by prismatic body and steam vent goes out the gas in the mold cavity, hinders again overflowing of molten metal; This venting plug is the steam vent of press-in die die cavity in the mold cavity; and make it rivet clasp; the air pressure that produces when preventing from casting ejects venting plug; thereby effectively prevent overflowing of molten metal; be conducive to 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.
Beneficial effect of the present invention 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 by the gap between venting plug and the steam vent rapidly, can not form vapour lock, causes poured short or produces and invade pore.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Embodiment:
As shown in drawings, a kind of venting plug for grinding ball casting mould venting hole comprises prismatic body 1, and the cross section of prismatic body 1 is square, and the front end of prismatic body 1 is truncated cone structure 2.
The present invention relies on four corner angle of venting plug and steam vent to realize interference fit in use, realizes the fixing of venting plug, and the interstitial row by prismatic body and steam vent goes out the gas in the mold cavity, hinders again overflowing of molten metal; This venting plug is the steam vent of press-in die die cavity in the mold cavity, and makes it rivet clasp, and the air pressure that produces when preventing from casting ejects venting plug.
