Core embedding casting method for middle trough casting

Abstract

The invention relates to a casting technology, in particular to a core embedding casting method for a middle trough casting, and solves the technical problems of low casting quality, low efficiency and the like due to low core setting quality in the conventional casting process. The core embedding casting method for the middle trough casting comprises the following steps of: arranging a core box at a sand core of the casting according to a part drawing of the casting; hammering the sand core according to the core box, and embedding the manufactured sand core into a mold in advance before molding; and starting a sand mixer for molding, directly taking the mold out to ensure that the sand core is directly embedded into a sand mold, and casting. By the casting method, the position of the sand core is very accurate, the sand mold is compact, casting quality is ensured, and production efficiency is improved.

Description

[0001] technical field [0002] The invention relates to a casting technology, in particular to a pre-embedded core casting method for a middle groove casting. technical background [0003] The current casting production process of our company is resin hardened water glass sand casting process, and the main production is scraper machine groove side, bracket column socket, belt machine parts and so on. Among them, the quality of castings directly affects the quality of our mechanical equipment and market competitiveness. In order to improve the comprehensive quality of castings, meet the supporting production needs of high-end coal machinery products of the group company and gradually adapt to the development of the external environment of the market. We must improve the quality of castings. After years of work, we found that according to the normal casting process requirements, all castings are cored according to the various shape requirements of the parts after molding. I...
