Pattern drying device for sand casting

Abstract

The invention relates to a pattern drying device for sand casting, which includes a drying rack for supporting the pattern, a moving mechanism drives the drying rack to be located in a drying room for drying operation, and the drying rack includes a bottom material receiving rod and a The material receiving rods on both sides, the material receiving rods and the material receiving rods on both sides are respectively wrapped with films, the positions of the above material receiving rods and the material receiving rods on both sides correspond to the position of the paint bracket, when the paint bracket moves to When the drying rack is in position, the bottom receiving rod and the lower support rod are misaligned, and the two side receiving rods are misaligned with the two side support rods, so that the entire pattern can be transferred to the drying rack to complete the transfer of the pattern. The receiving rod and the receiving rods on both sides are double-wrapped with a film, and the film is used to contact the pattern covered with paint, so that it can effectively solve the problem that the surface of the pattern is directly connected to the bottom receiving rod and the two sides. The complete problem ensures that the surface of the pattern is smooth, so as to ensure the surface quality of the subsequent casting products.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a pattern drying 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 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
