Embodiment Construction

[0015] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0016] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0017] Such as figure 1 and figure 2 As shown, the exhaust pipe sand core support according to the specific embodiment of the present invention is based on the original cylindrical structure, leaving a fixed space for holding molten iron in the middle and forming a fixed clamping space after it solidifies. The exhaust pipe sand core support The specific structure includes: a core support body 1 and a clamping space 2 for...

Abstract

The invention discloses a sand core support for an exhausting pipe. The sand core support comprises a cylindrical core supporting body and a clamping space, wherein the upper and lower circular end faces of the cylindrical core supporting body are supporting faces which are used for supporting a sand core and can guarantee the wall thickness of the exhausting pipe, and the outer circumferential surface of the cylindrical core supporting body is a fusion surface between the cylindrical core supporting body and casting molten iron; the clamping space is a circumferential annular groove formed in the middle of the fusion surface of the core supporting body. The sand core support for the exhausting pipe is of an I shape, the clamping space for containing the molten iron and fixing the solidified molten iron is formed in the middle of the sand core support, so that the problem that a core support falls off due to poor fusion between the core support and the molten iron can be effectively prevented, and potential quality hazards of the exhausting pipe are eliminated.

Description

technical field [0001] The invention relates to the field of exhaust pipe casting, in particular to an exhaust pipe sand core support. Background technique [0002] In the casting process of the exhaust pipe, after a large ladle of molten iron is transported to the casting site, it is divided into different handbags and cast into exhaust pipes one by one. It takes a long time and the temperature of the molten iron drops greatly. It is different from the temperature of the final pouring. The core strut cast in front can be well fused with the molten iron. When the casting temperature is too high, the core strut will even soften and cannot support the buoyancy of the sand core, causing the sand core to float up and the wall thickness in the middle of the casting to become thinner. In order to ensure the wall thickness of the exhaust pipe, the casting process generally uses a "cylindrical" core support with a relatively large core diameter, although it is more guaranteed to en...
