Manufacturing method for spiral cooling water jacket sand mold

Abstract

The invention belongs to the technical field of casting, and particularly relates to a manufacturing method for a spiral cooling water jacket sand mold. The method comprises the following steps that step 1, a cylindrical sand core is divided into two 180-degree semicircular sand cores for sand shooting molding respectively; step 2, reinforcing ribs are added at the two ends of each core head, so that each whole core head part is changed to be of a square frame structure, and the core head parts are bonded and fixed by using a simple special clamping fixture; and step 3, and the reinforcing ribs are sawed off to obtain the needed spiral water jacket sand core. The novel sand core manufacturing method is provided in the invention, the molding rate, and the density and the strength of the sand core can be well improved. Meanwhile, the mold structure can be greatly optimized, the mold structure is simple and is matched with equipment more easily, and the working efficiency is higher. The large-scale production requirement is met, and the problems that an existing mold is complex in structure and the sand core molding efficiency is low are solved.
