Vacuum casting pattern coating system

Abstract

The invention relates to a vacuum casting pattern coating system comprising a coating carrying frame. A transferring mechanism drives the coating carrying frame to move in a reciprocating manner between a coating groove and a feeding opening of a drying frame. The drying frame is used for bearing a pattern on the coating carrying frame. A moving mechanism drives the drying frame to conduct dryingoperation in a drying room. The pattern is transferred into the coating groove through the coating carrying frame, the pattern is dipped, then coating operation can be reliably conducted on the pattern, and the coating uniformity and reliability are ensured; the coated pattern is transferred into the drying frame through the coating carrying frame, the pattern is transferred to the drying frame, and the drying room is utilized to dry the pattern; after the pattern is dried, the pattern is detached from the drying frame; and then early-stage production of the pattern can be completed. The vacuum casting pattern coating system can significantly improve the pattern coating efficiency and coating uniformity and also can ensure the drying quality of the pattern.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a vacuum casting pattern coating system. 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 casting....

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
