The present embodiment provides a chaplet 3 for casting, including:
a first support sheet 301;
a second support sheet 302 arranged in parallel with the first support sheet 301;
a support bar 303 connected between the first support sheet 301 and the second support sheet 302; and
the connecting piece is arranged on the end face, back to the supporting rod 303, of the first supporting piece 301, and is provided with at least one first bending part 304 and at least two second bending parts 305, the first bending part 304 extends back to the first supporting piece 301, and the second bending parts 305 extend towards the first supporting piece 301;
at least two of the second bending portions 305 are oppositely arranged; the second bending portion 305 is gradually inclined outward from one end thereof away from the connecting piece to the other end thereof;
at least one of the first bending portions 304 and at least one of the second bending portions 305 are oppositely disposed.
During the casting process, a plurality of sand cores are used to form the internal structure of the casting. A plurality of sand cores are not integrated, so that the sand cores need to be arranged in a sand box according to a specific rule to form a specific molding cavity when the sand core molding machine is used. When molten iron is injected into the molding cavity, the molten iron can generate certain buoyancy on the sand core, so that the sand core needs to be fixed to ensure the configuration of the molding cavity.
Referring to fig. 1-3, the present embodiment provides a casting chaplet 3 for connecting between a first sand core 1 and a second sand core 2 so as to maintain a specific spacing between the first sand core 1 and the second sand core 2. In this embodiment, the entirety of the chaplet 3 is made of metal, and is welded inside the casting product along with the solidification of the molten iron.
The chaplet 3 of this embodiment includes a steel support and a connecting piece connected to the steel support. The steel support comprises a first support sheet 301, a second support sheet 302 and a support bar 303.
The first support sheet 301 and the second support sheet 302 are arranged in parallel. The support bar 303 is connected between the first support sheet 301 and the second support sheet 302. The steel support of this structure can play certain fixed effect but fixed effect is relatively poor. The steel support is connected between the first sand core 1 and the second sand core 2, the first supporting sheet 301 and the second supporting sheet 302 are respectively abutted against the first sand core 1 and the second sand core 2, a certain supporting effect can be achieved, but the steel support is easy to move between the first sand core 1 and the second sand core 2 and fall off, so that the distance between the first sand core 1 and the second sand core 2 is changed, and the forming of a casting is influenced.
In order to further improve the stability of the core support 3, the present embodiment provides a connecting piece at the end surface of the first supporting piece 301 facing away from the second supporting piece 302. The thickness of connection piece is 1 ~ 2mm, and the thickness of connection piece is too big can make the distance between first psammitolite 1 and the second psammitolite 2 bigger than normal, and consequently the thickness of setting up the connection piece is 1 ~ 2mm, can play further fixed effect, can not make the distance between first psammitolite 1 and the second psammitolite 2 produce great error again.
The connecting piece is provided with a first bending part 304 and three second bending parts 305 respectively. A first bending part 304 and three second bending parts 305 are connected with the connecting piece in a smooth transition way.
Two of the second bent portions 305 are disposed opposite to each other in the first direction, and the other second bent portion 305 and the first bent portion 304 are disposed opposite to each other in the second direction. The first direction and the second direction are perpendicular.
The first bent portion 304 extends away from the first support piece 301 so that the connection piece can be hung on the first sand core 1.
The three second bending portions 305 are arranged around the first supporting sheet 301, and extend towards the first supporting sheet 301, so that the side walls of the three second bending portions 305 can be respectively abutted to the edges of the first supporting sheet 301, and then act on the first supporting sheet 301 together to limit the first supporting sheet 301.
The first bending part 304 and the three second bending parts 305 are uniformly distributed on the connecting sheet. The three second bending portions 305 are gradually inclined outward from one end away from the connecting sheet to the other end thereof, so that one end of each second bending portion 305 away from the connecting sheet has a curved structure to prevent the end of the second bending portion 305 from damaging other members.
In this embodiment, an included angle of 60 to 80 degrees is formed between the first bending portion 304 and the end face of the connecting piece facing the first supporting piece 301, the first bending portion 304 is used for being installed in cooperation with the first sand core 1, and the first bending portion 304 can be stably hung on the first sand core 1 by setting the included angle.
The three second bending portions 305 and the end face, facing the first supporting sheet 301, of the connecting sheet are all at 90-110 degrees included angles. Therefore, the three second bending parts 305 can wrap the first supporting sheet 301 together, and the first supporting sheet 301 is well fixed.
In this embodiment, the chaplet 3 is arranged along the horizontal direction, and the first sand core 1 is arranged on the left side of the second sand core 2. In the present embodiment, the first bent portion 304 is hung on the upper end surface of the first sand core 1, so that the end surface of the connection piece facing away from the first support piece 301 abuts against the side wall of the first sand core 1. The end surface of the second support sheet 302 facing away from the first support sheet 301 abuts against the side wall of the second sand core 2. Whereby the chaplet 3 is connected between the first sand core 1 and the second sand core 2. When the first bending portion 304 is hung on the upper end surface of the first sand core 1, the second bending portion 305 disposed opposite to the first bending portion 304 may provide a vertically upward acting force to the first support sheet 301 so that the steel brace does not fall off. Meanwhile, the other two oppositely arranged second bending parts 305 can provide parallel acting forces in opposite directions for the first supporting sheet 301, so that the whole steel support cannot move back and forth to cause deviation.
In another alternative embodiment, the chaplets 3 are arranged in a vertical direction. The first sand core 1 is arranged above the second sand core 2. The first bent portion 304 is connected to the side wall of the first sand core 1, and the end surface of the connecting piece facing away from the first supporting piece 301 abuts against the lower end surface of the first sand core 1. The end surface of the second support sheet 302 facing away from the first support sheet 301 abuts against the upper end surface of the second sand core 2. Whereby the chaplet 3 is connected between the first sand core 1 and the second sand core 2. When the core support 3 is connected between the first sand core 1 and the second sand core 2, the two oppositely arranged second bending parts 305 can provide acting forces which are parallel and opposite in direction to the first supporting sheet 301 in the left-right direction, so that the first supporting sheet 301 is limited, and the whole steel support cannot move left and right.
The utility model discloses the principle and the implementation mode of the utility model are explained by applying the concrete embodiment, and the explanation of the above embodiment is only used for helping to understand the technical scheme and the core idea of the utility model; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
