3D printing sand mold continuous type six-face automatic sand cleaning machine and sand cleaning method

Abstract

The invention discloses a 3D printing sand mold continuous six-sided automatic sand cleaning machine, which includes a sand cleaning machine shell straddling a roller conveyor, and the front and rear sides of the sand cleaning machine shell are respectively provided with an entrance closed door and a The exit closed door, the top of the shell of the sand cleaning machine is provided with a lift-type sand blowing cover, the middle of the shell of the sand cleaning machine is provided with a bottom blowing frame below the roller conveyor, the top surface of the sand blowing cover, the surrounding side walls and The bottom blowing frame is equipped with blowing nozzles, which are connected to the solenoid valve controlled by PLC. The bottom of the sand cleaning machine shell is equipped with a mobile sand collecting box, and the side of the sand cleaning machine shell is equipped with a dust collector. A connected vacuum hood; at the same time, a continuous six-sided automatic sand cleaning method for 3D printing sand molds is disclosed. The invention not only improves the automation of sand cleaning work, greatly shortens the post-processing time of 3D printing sand molds, but also greatly improves the working environment of the sand cleaning process, which is beneficial to the health of operators.

Description

Technical field [0001] The invention relates to the technical field of sand core surface treatment in the foundry industry, in particular to a continuous six-sided automatic sand cleaning machine for 3D printing sand molds, and a continuous six-sided automatic sand cleaning method for 3D printing sand molds. Background technique [0002] In the field of foundry, when using traditional technology for sand casting, as the complexity of the shape and structure of the casting increases, the mold modeling becomes more difficult; and the digital manufacturing model represented by 3D printing technology uses one-time molding technology and can follow computer design drawings. Print out complex casting structure, so as to save materials, shorten the development cycle of parts and reduce manufacturing costs. Therefore, more and more sand casting companies at home and abroad, especially those that undertake high-end complex casting manufacturing and processing, have introduced 3D printing ...

AI Technical Summary

Problems solved by technology

[0004] The above method takes a long time to transfer, and the sand mold is prone to damage during the transfer process; manual sand cleaning is dusty, noisy, and inefficient, not only labor-intensive, but also has a poor operating environment, which seriously affects the health of employees; in addition, because 3D printing products Most of them are products with complex structures. In order to prevent the dead angle of sand cleaning, the sand mold needs to be hoisted and turned over continuously, and the nozzles are used for blowing.

The above problems have seriously restricted the industrial application of 3D printing technology in the field of casting
