Evanescent mode coating spraying system

Abstract

The invention discloses an evanescent mode coating spraying system which comprises a storage vat (1), a motor (2), a motor bracket (3), a stirring impeller (4), a feed delivery pipe (5), a return pipe (6), a connecting pipe (7), an output pipe (8), a feedback pipe (9), an air pipe (10), a pneumatic diaphragm pump (11), a magnetic filter (12), a first control valve (13), a second control valve (14), a third control valve (15), a fourth control valve (16), a spray pipe (17), a storage tank (18), a crown block (19), a lifting frame (20), a mounting rack (21), an evanescent mode coating (22), a mesh enclosure (23) and a fifth control valve (27). The evanescent mode coating spraying system has the advantages and effects that: during the evanescent mode coating process of the system, manpower and material resources as well as time are saved, the coating is uniformly coated, and cannot be limited by an evanescent mode structure, and deformation during the evanescent mode coating process is avoided.

Description

technical field [0001] The invention relates to tools in the field of mold casting, in particular to a spray system for lost foam paint. Background technique [0002] The traditional lost foam surface coating is painted by hand, which requires more workers and consumes a lot of consumables such as brushes, and the lost foam coating needs to be stirred frequently to keep it uniform. These manual operations are time-consuming, laborious and inefficient. The inevitable shedding in the process of dipping the paint by the brush also causes serious waste of the paint and pollution of the working environment. Due to the complex structure of the lost foam, some narrow or deep cavity parts are difficult to paint in place, resulting in structural blind spots and uneven paint thickness, which can easily cause problems such as sand inclusions and sand cleaning difficulties during casting, which seriously increases The difficulty and workload of sand cleaning and processing in the later...

[0002] The traditional lost foam surface coating is painted by hand, which requires more workers and consumes a lot of consumables such as brushes, and the lost foam coating needs to be stirred frequently to keep it uniform. These manual operations are time-consuming, laborious and inefficient. The inevitable spilling during the process of dipping the brush in the paint also causes serious waste of paint and pollution of the working environment

Due to the complex structure of the lost foam, some narrow or deep cavity parts are difficult to paint in place, resulting in structural blind spots and uneven paint thickness, which can easily cause problems such as sand inclusions in castings and difficulty in sand cleaning during casting, which seriously increases The difficulty and workload of sand cleaning and processing in the later stage will affect the quality of castings and the development cycle of molds

In addition, the main material of the lost foam is foam material, which has low rigidity. Workers need to turn it over many times during the painting process, which will easily lead to the deformation of the lost foam, seriously affect the precision of the casting, and even cause scrapping
