Cold core box mold for realizing sand grain flowing data visual collection

Abstract

The invention belongs to the related technical field of sand shooting core making and particularly discloses a cold core box mold for realizing sand grain flowing data visual collection. According tothe cold core box mold for realizing the sand grain flowing data visual collection, a mold unit comprises a first transparent cover plate, a metal core box and a second transparent cover plate which are connected in sequence, and the metal core box is provided with a sand shooting hole and an air exhaust plug; a first sealing gasket inside a sealing unit is arranged between the metal core box andthe first transparent cover plate, and a second sealing gasket is arranged between the metal core box and the second transparent cover plate; and a fixing unit fastens and connects the mold unit and the sealing unit to prevent generation of air leakage in the sand shooting process. By means of the cold core box mold for realizing the sand grain flowing data visual collection, the two sides of themetal core box are designed as the detachable transparent cover plates to observe the flowing situation of sand grains in the sand shooting process, so that the flowing data visual collection is realized, and meanwhile, by means of the arrangements of the sealing unit and the fixing unit, good tightness can be guaranteed under the premise of easy disassembly of the mold.

Description

technical field [0001] The invention belongs to the related technical field of core making by sand shooting, and more specifically relates to a cold box mold for realizing visual collection of sand flow data. Background technique [0002] Sand shooting core making is a core making process that uses the high-pressure gas of the sand shooting machine to uniformly inject molding sand into the cavity of the sand box for filling and compacting, and prepare the required sand core. Due to the fast filling speed, high compactness and high core shooting efficiency of the core sand in this process, it has been widely used in the casting process. [0003] During the sand shooting process, the change of the process parameters of the sand shooting machine, the structure of the cold box mold, the characteristics of the core sand particles and the binder all have a very important influence on the fluidity of the core sand, and the flow of the core sand particles in the mold The performanc...
