Fusible chaplet for thin-walled iron casting, application method and combined core

Abstract

A fusible chaplet for a thin-walled iron casting comprises an inner copper body and an outer tin layer wrapping the exterior of the copper body. The inner copper body is made of copper, and the outertin layer is made of tin; the inner copper body comprises a binding post, and an upper supporting seat and a lower supporting seat which are vertically connected to the two ends of the binding post; acombined core comprises an upper water jacket core, round bar cores and chaplets, and one upper water jacket core is provided; a plurality of round bar cores and chaplets are provided, and the roundbar cores correspond to the chaplets one by one; the top surface of the upper water jacket core is provided with a plurality of core units arranged continuously, and one round bar core is arranged above each core unit correspondingly; and one chaplet is arranged between each round bar core and each core unit. According to the design, not only can the more complete fusion between the chaplets and the casting be ensured, but also impurities are not introduced; and the anti-oxidation effect is better.

Description

technical field [0001] The invention relates to a core brace, which belongs to the field of casting, and in particular to a fusible core brace for thin-walled iron castings, an application method, and a combined core, which is specifically suitable for improving the fusion effect of the core brace and the casting without introducing impurities. Background technique [0002] Existing engine cylinder blocks are mostly manufactured by casting. During the manufacturing process, sand cores need to be placed in the sand box first, and then molten iron is injected for casting. [0003] The application publication number is CN105215294A, and the application publication date is January 6, 2016. The invention patent application discloses a core support, which includes a core column, a pair of bases and connectors. The core column includes oppositely arranged first ends and At the second end, a pair of bases are respectively detachably connected to the first end and the second end, and...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the defects and problems of incomplete fusion between the core support and the casting in the prior art, and provide a fusible core support for thin-walled iron castings with relatively complete fusion between the core support and the casting, its application method, and its combination core
