Problems solved by technology

However, the process of nailing the core can easily drop the sand on the sand core into the mold, resulting in sand inclusion defects in the casting. At the same time, the sand core is not firmly fixed, causing problems such as core drift and choking.
In addition, this production method requires the production of multiple sand cores in the core-making process and the assembly of sand cores in the box-assembling process, which seriously restricts the production efficiency

Abstract

The invention provides a core box for producing a conjoined sand core. The core box includes: a base plate; at least one intermediate plate vertically connected to the base plate; a detachably connected retractable core plate around the intermediate plate and the base plate; and a core rod passing through the at least one intermediate plate in order and detachably connected to the at least one intermediate plate. The invention aims to provide a core box for producing a conjoined sand core, the core box can reduce sand inclusion, core floatation and chocking quality problems of castings and improve the production efficiency of castings. The invention also provides a method for producing the conjoined sand core.

Description

technical field [0001] The invention relates to a core box and a method for producing one-piece sand cores, and is especially suitable for the casting production of machine tool castings with multiple disconnected inner cavity structures. Background technique [0002] For many machine tool castings, such as bases, saddles, etc., the inner cavity structure has multiple cavities that are not connected to each other. During the casting process, multiple sand cores corresponding to the cavity structure of the casting are produced in the core making process. The box process assembles these sand cores and molds in turn. During assembly, it is necessary to nail the core support on the side of each individual sand core to fix the sand core. After pouring, the core support is fused with the casting. That is, the wall thickness of the casting cavity. However, during the nailing process, it is easy to drop the sand on the sand core into the mold, resulting in sand inclusion defects in...
