Abstract
The utility model provides a vent plug structure, its simple structure, it effectively avoids the sand flow to plug up the exhaust hole, guarantees that the air current is unobstructed, prevents to produce the negative pressure in the die cavity for sand mould after the shaping conveniently takes out, but also effectively avoided taking out the in-process and damaged the sand mould, and it includes the exhaust cock body, be provided with the exhaust hole on the exhaust cock body, its characterized in that: the exhaust hole is an inverted V-shaped hole, and the aperture of the air inlet end is smaller than that of the air outlet end.
Description
Technical Field
The utility model relates to a technical field of casting equipment part, in particular to core vent structure.
Background
In-process in the casting mould, for guaranteeing that the psammitolite after the shaping conveniently takes out simply, will set up the exhaust hole in sand mould die cavity, current exhaust hole is mostly cylindrical, is spouting the sand in-process because the core vent hole can be plugged up to the sand, leads to exhausting not smooth, leads to producing the negative pressure in the die cavity for the sand mould after the shaping takes out the difficulty, but also can damage the sand mould taking out the in-process.
Disclosure of Invention
To the technical problem, the utility model provides a vent plug structure, its simple structure, it effectively avoids the sand flow to plug up the exhaust hole, guarantees that the air current is unobstructed, prevents to produce the negative pressure in the die cavity for sand mould after the shaping conveniently takes out, but also has effectively avoided taking out the in-process and damaged the sand mould.
The technical scheme is as follows: the utility model provides a vent plug structure, its includes the vent plug body, be provided with the exhaust hole on the vent plug body, its characterized in that: the exhaust hole is an inverted V-shaped hole, and the aperture of the air inlet end is smaller than that of the air outlet end.
It is further characterized in that: the exhaust plug body is provided with a plurality of exhaust holes; the exhaust holes are three exhaust holes; the exhaust holes are transverse strip-shaped exhaust holes.
The above structure is adopted in the utility model, because the exhaust hole is the shape of falling V-arrangement hole, it is less than the end aperture of giving vent to anger to advance sand end aperture for the sand on the entering core vent blocks up when the exhaust hole tip, get into the large aperture position with the sand through appropriate pressure, make the sand discharge through the great sand outlet of bore fast, avoided the jam in exhaust hole, it is unobstructed to guarantee the air current, prevent to produce the negative pressure in the die cavity, make the sand mould after the shaping conveniently take out, and still effectively avoided taking out the in-process and damaged the sand mould.
Drawings
FIG. 1 is a schematic view of the structure of the vent plug of the present invention;
fig. 2 is a sectional view of the structure of the vent plug of the present invention.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
If fig. 1, fig. 2, a core vent structure, it includes core vent 1, be provided with three exhaust holes 2 on the core vent 1, exhaust hole 2 is the horizontal strip vent hole of falling the V-arrangement, it is less than sand outlet end 4 apertures to advance 3 apertures in the sand end, make the sand that gets into on the core vent when exhaust hole tip blocks up, get into the large aperture position with sand through appropriate pressure, make sand discharge through the great sand outlet fast of bore, the jam in exhaust hole has been avoided, guarantee that the air current is unobstructed, prevent to produce the negative pressure in the die cavity, make the sand mould after the shaping conveniently take out, and still effectively avoided taking out the in-process and damaged the sand mould.
The present invention and the embodiments thereof have been described above schematically, and the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto, and those skilled in the art will be suggested by the teachings thereof, and without departing from the spirit of the present invention, without creatively designing the structural mode and the embodiments similar to the technical solution, all of which shall fall within the protection scope of the present invention.
Claims (4)
