Description

Technical Field

[0001] The utility model relates to the technical field of sand mold casting, in particular to a sand box for sand mold casting which is convenient for pouring sand. Background Art

[0002] Sand casting is a widely used form of casting, which mainly uses sand to make molds. This process involves placing a finished part model or a wooden model (pattern) in the sand, and then filling the sand around the pattern. After the pattern is taken out of the box, the sand forms a mold. In order to remove the model before casting the metal, the mold should be made into two or more parts. During the mold making process, holes and vents for pouring metal into the mold must be reserved to form a pouring system. After the mold is poured with liquid metal, it is kept for a suitable time until the metal solidifies. After the part is taken out, the mold is destroyed, so a new mold must be made for each casting. The main process steps of sand casting include mold making, preparatory work before pouring, pouring, trimming, machining, surface treatment and heat treatment, etc. It is one of the metal pouring processing methods and also a basic metal heat processing method.
