Mold coating device for grit casting

Abstract

The invention relates to a mold coating device for grit casting. The mold coating device for grit casting includes a coating propping rack. A transferring mechanism drives the coating propping rack tomove in a coating groove. An enclosure rack is placed on the upper face of the coating propping rack. An enclosure cavity of a card placing mold is formed between the enclosure rack and the coating propping rack. A vertical driving mechanism drives the coating propping rack and the enclosure rack move vertically and makes the mold immersed in the coating groove. Put the mold on the coating rack and transfer the mold into the coating groove by the coating propping rack to make the mold immersed so that the coating operation of the mold can be achieved reliably, and the evenness and the degreeof reliability of coating are guaranteed. The device can improve the mold coating efficiency and the coating evenness greatly simultaneously, and guarantees the drying quality of the mold.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a pattern coating device for sand casting. Background technique [0002] Sand casting is a common production method for general structural components. The patterns used are generally polymer materials. For example, after polystyrene foam is produced through a mold, it is necessary to apply a high-temperature resistant coating on the surface of the pattern and then dry it. Produce qualified patterns to ensure the quality of castings in subsequent actual casting. When implementing pattern production, it is necessary to use a spraying machine to carry out a full range of spraying operations on a single or a certain number of patterns, and after the spraying is completed, they are placed on the drying rack respectively, and then the rapid drying operation is performed. After the pattern is placed on the drying rack and dried, the pattern product can be obtained for subsequent castin...

Problems solved by technology

When implementing pattern production, it is necessary to use a spraying machine to carry out a full range of spraying operations on a single or a certain number of patterns, and after the spraying is completed, they are placed on the drying rack respectively, and then the rapid drying operation is performed. After the pattern is placed on the drying rack and dried, the pattern product can be obtained for subsequent casting. When the above pattern is produced, it is difficult to achieve uniform coverage in actual spraying, and when the spraying is finished There is also a relatively serious hang phenomenon in the pattern. After being placed directly on the drying rack, the paint falls on the drying rack after the paint is placed on the drying rack. When the pattern is taken out of the drying rack, it will dry The paint is easy to get stuck on the drying rack, causing serious paint loss on the surface of the pattern, which has a great impact on the quality of subsequent casting products
