Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary demoulding equipment, in particular to a reactor coil mold flipping demoulding equipment. Background Art

[0002] Sand casting is a widely used form of casting. As the name suggests, it is to make a mold with sand. Sand casting requires placing the finished part model in a sand box filled with sand, and then filling the sand around the pattern. After the pattern is taken out of the box, the sand forms a mold.

[0003] When demolding sand casting, operators usually clean the sand manually after casting and take out the cast parts inside for processing. However, this method is inefficient for batch-produced workpieces. Existing equipment can also flip the mold after hoisting to quickly separate the internal castings. However, this method is prone to accidents such as bumps on the castings during use, resulting in bending or breaking of weak parts of the castings, resulting in an increase in the defective rate. In addition, the cast sand needs to be screened with the help of external equipment after a single casting to avoid metal debris mixed inside. For this reason, we propose a reactor coil mold flipping and demolding equipment to solve the above problems. Utility Model Content
