Wooden mold suitable for carbon dioxide hardened water glass sand molding and its application method

Abstract

The invention relates to a wood mold suitable for carbon dioxide hardened sodium silicate sand molding. The wood mold comprises a wood mold body, wherein a mold withdrawing angle is not formed in the wood mold body; the wood mold body is formed by splicing multiple branch wood molds; drawing parts are arranged on the branch wood molds; the connecting surface between two adjacent branch wood molds is an inclined surface; and the angle of the inclined surface ranges from 30 degrees below zero to 30 degrees. The wood mold disclosed by the invention has the beneficial effects that a mode of segmenting the wood mold is adopted, the mold withdrawing angle does not need to be formed, and after one branch wood mold is drawn during mold drawing after molding, the other branch wood molds can be easily taken out. Therefore, the problem that the mold withdrawing angle is formed is solved, the economical benefits are improved, the labor and time are saved, and the overall economic benefits are obvious.

Description

technical field [0001] The invention relates to a wooden mold suitable for carbon dioxide hardened water glass sand molding and a use method. Background technique [0002] When making wooden molds for large castings, it is often necessary to increase the thickness to set the draft angle in order to facilitate the drawing of the mold. The castings made of such wooden molds need subsequent processing to remove the increased wall thickness after molding, which is time-consuming and laborious, resulting in unnecessary waste. Contents of the invention [0003] The object of the present invention is to provide a kind of wood model and using method that are applicable to carbon dioxide hardened sodium silicate sand molding for the above deficiencies. [0004] The solution adopted by the present invention to solve the technical problem is that a wooden mold suitable for carbon dioxide hardened water glass sand molding includes a wooden mold body, the wooden mold body is not provi...
