Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Referring to fig. 1, a core box convenient for filling core sand provided by this embodiment includes a first box body 1 and a second box body 2, a first groove is formed inside the first box body 1, a first splicing surface is formed at an edge of the first box body, a second groove is formed inside the second box body 2, a second splicing surface is formed at an edge of the second box body, and the first splicing surface and the second splicing surface are overlapped to realize splicing and matching of the first box body 1 and the second box body 2;

after the first box body 1 and the second box body 2 are spliced, the first groove and the second groove are matched to form a sand filling space;

the sand filling space takes a superposed surface of the spliced first splicing surface and the spliced second splicing surface as a symmetrical surface.

Because the core box is formed by splicing the first box body 1 and the second box body 2, when core sand is filled, the first box body 1 and the second box body 2 can be separated, and then the core sand is respectively filled into the first box body 1 and the second box body 2, so that the core sand can be conveniently put into the core box; and because the symmetrical surface of the sand filling space is superposed with the first splicing surface and the second splicing surface, core sand can be filled into a deeper or narrower local space inside the first box body 1 and the second box body 2, so that the convenience of filling the core sand is greatly improved.

It should be noted that, if the external shape of the sand core itself is asymmetric, the first splicing surface and the second splicing surface may be curved surfaces, or planes that facilitate filling of the core sand into the first box 1 and the second box 2.

Wherein in a preferred embodiment for further improving the convenience of filling core sand, the first box 1 comprises:

the first layered body 11, the first layered body 11 is located at one end of the first box body 1;

the second layering body 12, the second layering body 12 is located at the other end of the first box body 1;

a plurality of third layering bodies 13, wherein the third layering bodies 13 are disposed between the first layering body 11 and the second layering body 12.

Since the first box body 1 can be divided into the first layered body 11, the second layered body 12 and the third layered body 13, when filling core sand into the first box body 1, the first layered body 11, the second layered body 12 and the third layered body 13 can be filled respectively, and then the first layered body 11, the second layered body 12 and the third layered body 13 are sequentially spliced to obtain a sand core. That is, in the process of filling the core sand, the core sand can be more conveniently filled in the first groove of the first box body 1, especially in a narrow part in the first groove. In addition, when the sand core is manufactured in a small volume, only one or more of the first layered body 11, the second layered body 12 and the third layered body 13 need to be used, so that the sand core is saved. The convenience of filling the core sand is further improved.

Here, the first container 1 is not limited to be layered, and the second container 2 may be layered as the first container 1.

Wherein in a preferred embodiment for improving the use convenience of the core box, a clamping pin and a clamping hole structure are formed between each layered body 11 and the adjacent layered body 11.

As the clamping pin and the clamping hole structure are formed between each layered body 11 and the adjacent layered body 11, the adjacent layered bodies 11 can be spliced and fixed through the clamping pin and the clamping hole structure, and the use convenience of the core box is further improved.

Wherein, in a preferred embodiment for improving the use convenience of the core box, a bayonet and a bayonet hole structure are formed between each layered body 11 and the second box body 2.

As the clamping pin and the clamping hole structure are formed between each layering body 11 and the second box body 2, the layering bodies 11 and the second box body 2 can be spliced through the clamping pin and the clamping hole structure, and the use convenience of the core box is further improved.

In a preferred embodiment of the core box for improving the quality of the sand core manufactured by the core box, the core box further comprises a splicing hoop 3, and the splicing hoop 3 is arranged around the first box body 1 and the second box body 2.

As shown in fig. 2, the clamp 3 is arranged between the first box body 1 and the second box body 2 of the core box in a surrounding manner, so that the first box body 1 and the second box body 2 can be fixed more firmly, and the manufactured sand core has higher quality.
