Method for reducing profile size of core bag

Abstract

The invention relates to a method for reducing the profile size of a core bag, and belongs to the technical field of casting. The method is used for achieving the purpose that a sand box with a certain volume can accommodate a core bag with the larger profile size. The method comprises the following steps that 1), when a three-dimensional model of a sand mold or a sand core is designed, clamping holes are formed in two opposite end surfaces of the sand core and / or sand mold; and the clamping holes are embedded in the end surface of the sand mold or the sand core, so that the profile size of the sand mold or the sand core is not increased; and 2), an independent lifting handle is produced, wherein the lifting handle is made of an aluminum alloy material, the lifting handle is provided witha matching portion and a hanging portion, the matching portion is matched with the clamping holes, the lifting handle can be connected with the sand core or the sand mold, the lifting portion can be connected with transfer equipment, and lifting of the sand core or sand mold can be realized. According to the method for reducing the profile size of the core bag, the reduction of the profile size ofthe core bag is realized, so that the purpose that the same sand box can accommodate the larger core bag can be achieved.

Description

technical field [0001] The invention relates to the technical field of molding sand casting, in particular to the molding and core-making process of sand molds and sand cores. Background technique [0002] Sand cores and sand molds form core packages after core assembly. Before core assembly, sand cores and sand molds need to undergo sand blowing, cleaning, coating, surface drying and other processes after core making and molding. During the process, it is necessary to perform various operations such as transfer, grabbing, and flipping of sand cores and sand molds. Therefore, it is necessary to install handles, clamping holes, etc. on sand cores and / or sand molds, and reserve clamping devices at the same time. clamping space. When the sand box is fixed, the contour size of the core package cannot exceed a certain range, otherwise the core package cannot be placed into the sand box. [0003] In the prior art, the method to solve the limitation of the contour size of the cor...

Problems solved by technology

[0004] In view of the large workload and low efficiency caused by removing the hanger when the above-mentioned core package outline size is limited by the size of the sand box, it is necessary to propose a method for reducing the core package outline size. By setting the movable handle, the workload of removing the handle is avoided
