Abstract

The invention relates to a valve pouring molding cooling process, which mainly solves the problem of low processing efficiency of the valve pouring molding in the prior art. 1) After the molding sand is dried, it is divided into two parts, namely the first molding sand and the second Second molding sand; 2) Fill the first molding sand in the sand mold, and embed a cooling device in the sand mold; 3) Die-cast a metal plate through a stamping process to form a heat conducting plate that matches the structure of the part; 4) Put the heat conducting plate Cover the first molding sand of the sand mold; 5) Mix the rest of the second molding sand with the binder evenly, and evenly cover the mixed second molding sand and binder on the upper surface of the heat conducting plate and solidify to form a mold cavity 6) pour the liquid metal into the mold cavity, after the pouring is completed, turn on the water pump to pump the cooling water into the water guide pipe and the heat dissipation pipe to quickly discharge the heat on the heat conducting plate, so as to improve the solidification of the liquid metal in the mold cavity.

Description

Technical field [0001] The present invention relates to a valve casting forming cooling process. Background technique [0002] The valve acts in the entire pipe. According to the use of the valve, casting and forging processes are mainly applied. Different molding processes directly affect the valve use strength, and a good molding process can greatly increase the service life of the valve. [0003] Casting processes are also referred to as casting molding processes, and is a method of casting liquid metal into a mold cavity that is adapted to the shape of the part to obtain a part or blank of surface quality of a certain shape size. In this casting process, the time for natural cooling is waiting after the metal liquid casting is completed, and the cooling device is often provided on the mold for rapid cooling, thereby improving processing efficiency, but 90% of the valve processing plant In the forming process, sand casting is used, while the basic raw material of the cast sand...
