A kind of internal treatment device of foundry sand box and internal treatment process of foundry sand box

Abstract

The present invention relates to a casting sand box internal treatment device and casting sand box internal treatment process, comprising a collection base, a telescopic tube, a working air pump, an annular frame, a working frame, a cleaning unit, a support column and a support unit. A telescopic cylinder is installed in the middle, and an annular frame is installed on the outer wall of the lower end of the telescopic cylinder. A working air pump is installed on the upper end of the annular frame through the base, and a working frame is installed on the upper end of the telescopic cylinder. There is a cleaning unit in the working frame, and a The support column, the lower end of the support column is installed on the collection base, and the upper end of the support column is installed with a support unit. The invention can solve the problem that after the sand box is cleaned, there are many sand grains left in the cleaned sand box, and the personnel usually tilt the sand box upside down and clean it with a brush. Since the sand box has a certain weight, the personnel hold the sand box in a tilted state for a long time You will feel tired when turning the sand box upside down, it is difficult to see the inside of the sand box when cleaning, and it is difficult to collect the sand particles after cleaning.

Description

technical field [0001] The invention relates to the technical field of casting sand box treatment, in particular to a casting sand box internal treatment device and a casting sand box internal treatment process. Background technique [0002] Sand casting is a kind of casting process. The mold used in sand casting is generally composed of outer sand mold and core. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to single-piece production, batch production and mass production of castings, and the castings have long service life and high precision. [0003] In the sand casting production line, it is necessary to clean the inside of the sand box after the casting is demolded. After cleaning, there are many sand particles in the sand box. The personnel usually tilt the sand box upside down and clean it with a brush. However, due to sand The box has a certain weight, and personnel will feel...
