Novel structure for enhancing conduction efficiency of casting hot core box

Abstract

The invention relates to a novel structure for enhancing conduction efficiency of a casting hot core box. The structure comprises an upper core box body, upper core box cup mounting grooves, upper core box cups and copper bar fixing holes, wherein the six upper core box cup mounting grooves are formed in the upper side of the upper core box body, and the six upper core box cups are embedded fixedly in the inner sides of the upper core box cup mounting grooves respectively. According to the novel structure for enhancing the conduction efficiency of the casting hot core box, the eccentric copperbar fixing hole is formed in the arranged upper core box cup, a heat conduction copper bar is inlaid in the copper bar fixing hole, the heat conduction copper bar needs to be tightly matched in the copper bar fixing hole, a large copper bar is inlaid in the copper bar fixing hole in the upper core box cup of a solid mold steel structure, so that the heat conduction efficiency is improved, the local temperature of the mold is effectively improved, the process requirements are met, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing auxiliary special equipment, in particular to a novel structure for enhancing the conduction efficiency of a casting hot core box. Background technique [0002] The hot core box method is a method of machine-made cores in foundry production. The sand material mixed with foundry sand, thermosetting resin and catalyst is injected into the core box with heating device, heated to 250-320 degrees Celsius, so that the sand material close to the surface of the core box is heated, and under the action of temperature, its binder It can be polycondensed and hardened in a short period of time to form a core without going into an oven for drying, which has the advantages of shortening the production cycle. Moreover, as long as the surface layer of the sand core has a millimeter to form a hard shell, it can be taken out from the core box, and the sand core in the central part can be hardened by its...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a new structure for strengthening the conduction efficiency of the casting hot core box, so as to solve the problem that the middle cup structure of the existing cylinder water jacket hot core box proposed in the above background technology is a solid mold steel, which is heated from the core box body. The tube is far away, because the conduction efficiency is not enough, the temperature here cannot reach the temperature required by the process during production, resulting in insufficient curing of the sand core, so the curing time must be extended, thus reducing the problem of production efficiency
