Problems solved by technology

However, in the prior art, when the loose block is placed on the steep surface of the wooden mold, it is very easy to fall off and is not easy to fix; when the mold is pulled out, a small part of the loose block is surrounded by molding sand, and it is usually necessary to swing the loose block from side to side. Knock, and then pull out the loose block after it is loose, which will make the size of the sand mold larger, and the size of the castings produced will have a certain deviation. improved work efficiency

Description

technical field [0001] The invention relates to the field of casting, in particular to a wooden mold with movable blocks. Background technique [0002] Wooden molds and loose blocks are usually used in the casting process. It is necessary to place loose blocks on the wooden mold and then place molding sand, and then lift the mold. However, in the prior art, when the loose block is placed on the steep surface of the wooden mold, it is very easy to fall off and is not easy to fix; when the mold is pulled out, a small part of the loose block is surrounded by molding sand, and it is usually necessary to swing the loose block from side to side. Knock, and then pull out the loose block after it is loose, which will make the size of the sand mold larger, and the size of the castings produced will have a certain deviation. work efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wooden mold with loose pieces,...
