Furthermore, a sprue which penetrates through the top wall of the sand box body is connected to the model body, a sprue cup which is located outside the sand box body is arranged at the upper end of the sprue, a cross runner is connected to the lower end of the sprue, and an inner sprue is arranged at the tail end of the cross runner.
Furthermore, the model body is made of copolymer foam, and the surface of the model body is sprayed with an isolation coating.
Compared with the prior art, the beneficial effects of the utility model are that: in the process that the casting is formed into a solid state from a liquid state, through vibration interference of the high-frequency vibrator, dendritic crystals generated in the forming process are broken, intergranular cracks are eliminated, the density of the casting can be improved, and the yield of the casting is greatly improved.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a schematic structural diagram of a second embodiment of the present invention;
the casting mold comprises a mold body 1, a sand box body 2, a sprue 3, a sprue cup 4, a runner 5, an inner sprue 6, a high-frequency vibrator 7, a sand material 8 and a vibration connecting rod 9.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.
In the first embodiment, referring to fig. 1, a casting processing device includes a sand box body 2 with a built-in model body 1, the model body 1 is made of copolymer foam, an isolation coating is sprayed on the surface of the model body 1, a sand material wrapping the model body 1 is arranged in the sand box body 2, a sprue 3 penetrating through the top wall of the sand box body 2 is connected to the model body 1, a sprue cup 4 located outside the sand box body 2 is arranged at the upper end of the sprue 3, a cross runner 5 is connected to the lower end of the sprue 3, an inner sprue 6 is arranged at the tail end of the cross runner 5, and a high-frequency vibrator 7 for vibrating the sand box body 2 is arranged on the sand box body 2; when the casting method is implemented, the sand 8 in the sand box body 2 is processed in a negative pressure state through vacuum pumping, under the action of atmospheric pressure, the sand 8 in the sand box body 2 can form a sand mold with certain strength, then molten steel in a molten state is injected into the sprue 3 through the sprue cup 4, then flows into the cross runner 5, and finally flows into a cavity of the sand mold through the inner sprue 6, and dendritic crystals can be formed in the cooling process after the molten steel is fully poured (traditional dendritic crystals cannot be supplemented by the molten steel during cooling shrinkage due to the obstruction of the dendritic crystals, and shrinkage cavities or cracks are formed to cause poor air tightness of castings).
In the second embodiment, referring to fig. 2, a casting processing device includes a sand box 2 with a built-in mold body 1, the mold body 1 is made of copolymer foam, an isolation coating is sprayed on the surface of the mold body 1, a sand material 8 wrapping the mold body 1 is arranged in the sand box 2, a sprue 3 penetrating through the top wall of the sand box 2 is connected to the mold body 1, a sprue cup 4 located outside the sand box 2 is arranged at the upper end of the sprue 3, a runner 5 is connected to the lower end of the sprue 3, an inner sprue 6 is arranged at the end of the runner 5, a high-frequency vibrator 7 for vibrating the sand box 2 is arranged on the sand box 2, a vibrating connecting rod 9 penetrating through the sand box 2 is connected to the high-frequency vibrator 7, the end of the vibrating connecting rod 9 is connected to the mold body 1, in the same technical scheme, the high-frequency vibrator 7 drives the sand box 2 to vibrate during the cooling process after the molten steel is filled in a cavity, meanwhile, the model body 1 is driven to vibrate by the vibration of the vibration connecting rod 9, and the dendritic crystals are broken by the combination of external vibration and internal vibration, so that molten steel is timely supplemented into gaps among the dendritic crystals, and the density of the formed casting is further improved.
In addition, high frequency electromagnetic shaker 7 is the application to prior art product in this application, and the concrete model can be selected: HD-C50/GZ100/GZ150, etc.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
