Abstract
The utility model provides a green sand mould inserted block structure, its simple structure, it guarantees that the sand mould takes out simply conveniently, prevents effectively moreover that the sand mould from taking out the damage of in-process, and it includes sand mould inserted block body, its characterized in that: and an exhaust groove is formed in the bottom of the sand mould block body.
Description
Technical Field
The utility model relates to a technical field of casting equipment part, in particular to wet sand mould inserted block structure.
Background
In the casting mould, in the damp pattern sand mould, in order to guarantee the complete taking out of the sand mould and avoid the damage of the sand core in the taking-out process, the depth in the sand mould is usually less than the width of the sand mould, when the sand mould is very deep, negative pressure can be generated in a cavity of the sand mould during the molding of the sand mould, the molded sand mould can be taken out difficultly, and the sand mould is easy to damage during the taking-out.
Disclosure of Invention
To the technical problem, the utility model provides a green sand mould inserted block structure, its simple structure, it guarantees that the sand mould takes out simply conveniently, prevents effectively moreover that the sand mould from taking out the damage of in-process.
The technical scheme is as follows: the utility model provides a wet sand mould abaculus body structure, its includes sand mould abaculus body, its characterized in that: and an exhaust groove is formed in the bottom of the sand mould block body.
It is further characterized in that: the exhaust groove is in a strip shape; the exhaust groove is formed by wire cutting; a plurality of exhaust grooves are formed in the bottom of the sand mould embedded block body; the exhaust grooves are uniformly arranged; an elastic stripping hemisphere is arranged at the bottom in the sand mould embedded block body.
The above structure is adopted in the utility model, because be provided with the air discharge duct on the sand mould abaculus body bottom for the air discharge of die cavity when darker sand mould shaping prevents to produce the negative pressure in the die cavity, guarantees that the sand mould takes out simple and conveniently, prevents effectively moreover that the sand mould from taking out the damage of in-process.
Drawings
FIG. 1 is a schematic view of the structure of a green sand mold insert of the present invention;
fig. 2 is a top view of fig. 1.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 and 2, the green sand mold insert structure comprises a sand mold insert body 1, a plurality of strip-shaped exhaust grooves 2 are formed in the bottom of the sand mold insert body 1 through wire cutting, the exhaust grooves are uniformly arranged, and the exhaust grooves are formed in the bottom of the sand mold insert body, so that air in a cavity is discharged during deep sand mold forming, negative pressure is prevented from being generated in the cavity, a sand mold is taken out simply and conveniently, and the sand mold is effectively prevented from being damaged in the process of taking out the sand mold. The bottom is provided with elasticity drawing die hemisphere 3 in the sand mould abaculus body 1, has increased internal tension, by form air discharge duct and elasticity drawing die hemisphere cooperation, has further guaranteed taking out of shaping back 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 (5)
1. The utility model provides a wet sand mould abaculus body structure, its includes sand mould abaculus body, its characterized in that: the sand mould is provided with the air discharge duct on the abaculus body bottom, the air discharge duct is the bar form.
