Abstract

The invention discloses a casting box using a novel material, the casting box comprises the following components in parts by weight: 30-50 parts of molding sand, 1-5 parts of phenolic resin, 5-10 parts of a powdery coupling agent, 10-20 parts of water and 15-25 parts of carbon dioxide, the casting box is formed by mixing the molding sand, the phenolic resin, the powdery coupling agent and the water, molding, blowing carbon dioxide gas in a vacuum environment, and curing. And a forming cavity is formed in the box body, and the box body is used for casting metal products. According to the invention, the problems that the traditional material seriously pollutes the environment, does not meet the theme requirement of current national green casting and cannot fully meet the production requirement of casting the 350km axle box body are solved.

Description

technical field [0001] The invention relates to the technical field of casting boxes, in particular to a casting box using new materials. Background technique [0002] At present, with the rapid development of China's high-speed rail, the demand for 350km cast axle boxes is relatively large, and domestic manufacturers all use traditional techniques and materials, which have long production cycles and high costs, and traditional materials have serious environmental pollution, which does not meet the current requirements of the country. The theme requirements of green casting cannot fully meet the production demand for cast 350km axle boxes. Now there is an urgent need for suppliers who can produce in batches and have a short production cycle. Under this background, it is imminent to develop new processes and materials. Contents of the invention [0003] In order to solve the problem that traditional materials have serious environmental pollution, do not meet the current nat...
