Abstract
The utility model relates to a large-scale excvavtor ultra precision multi-circuit control main valve body sand mould, which comprises a shell mould and a slender mould core which is arranged in the shell mould, and the innovative points are that a hollow core bar is embedded in the mould core, and the surface of the hollow core bar is distributed with cellular small holes. The large-scale excvavtor ultra precision multi-circuit control main valve body sand mould has the advantages that the core bar of the mould core is arranged in a hollow shape, the surface is distributed with the cellular small holes, thereby leading the mould core to have excellent air permeability when meeting strength demands, and guaranteeing the quality of a large-scale excvavtor ultra precision multi-circuit control main valve body.
Description
Technical field
The utility model relates to a kind of foundry sand type, the accurate multichannel control of particularly a kind of large excavator superelevation valve body of main valve sand mold.
Background technology
When the accurate multichannel control of casting large excavator superelevation valve body of main valve, at first need to make sand mold, because this valve body has several elongated main valve hole, this hole is elongated flexible, need in the core of sand mold, arbor be set, general arbor is a solid construction, and when there was shortcoming in it: solid arbor exhaust was very difficult, easily produces defectives such as pore.
The utility model content
The technical problems to be solved in the utility model provides the accurate multichannel control of the large excavator superelevation valve body of main valve sand mold that a kind of good exhaust effect is difficult for producing pore.
For solving the problems of the technologies described above, the technical solution of the utility model is: the accurate multichannel control of a kind of large excavator superelevation valve body of main valve sand mold, comprise shell mould and place the interior elongated core of shell mould, its innovative point is: be embedded with hollow arbor in the described core, the surface of described hollow arbor is be covered with aperture cellular.
Advantage of the present utility model is: the arbor of core is set as hollow shape, and at the full cellular aperture of surface distributed, make core when satisfying requirement of strength, have the high ventilation performance, guarantee the quality of the accurate multichannel control of casting large excavator superelevation valve body of main valve.
Description of drawings
Accompanying drawing is the accurate multichannel control of a utility model large excavator superelevation valve body of main valve sand mold structural representation.
The specific embodiment
As shown in drawings, comprise shell mould 1, core 2, hollow arbor 3.
The shell mould 1 of the accurate multichannel control of the above-mentioned large excavator superelevation that is used to cast valve body of main valve is built-in with the elongated core 2 that is shaped to main valve hole, and these core 2 centers are embedded with hollow arbor 3, and its surface is for being covered with the cellular of aperture.
During casting, molten iron enters the cavity between shell mould 1 and the core 2, and the gas at center is discharged by hollow arbor 3, and exhaust performance is good, does not have blow hole.
Claims (1)
1. the accurate multichannel control of a large excavator superelevation valve body of main valve sand mold comprises shell mould and places the interior elongated core of shell mould that it is characterized in that: be embedded with hollow arbor in the described core, the surface of described hollow arbor is be covered with aperture cellular.
