Embodiment Construction

[0023] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] Embodiments of the invention are:

[0025] A valve casting molding cooling process, comprising the following steps:

[0026] 1) After the molding sand is dried, it is divided into two parts, namely the first molding sand and the second molding sand;

[0027] 2) Fill the first molding sand in the sand mold 1, and embed the cooling device 2 in the sand mold 1, refer to figure 1 , figure 2 , image 3 and Figure 4 As shown, the cooling device 2 includes water guide pipes 21 arranged horizontally, three heat dissipation pipes 22 arranged vertically, and a pumping device 23 that accelerates the flow of cooling water in the heat dissipation pipes 22. Radiating fins 3 are arranged on the outer surface, so as to speed up the heat exchange efficiency of the heat dissipation pipe 22. The heat dissipation pipe 22 is a straight-through pipe fitting,...

Abstract

The invention relates to a valve casting molding and cooling technology, and mainly solves the problem of low valve casting molding processing efficiency in the prior art. The technology includes thefollowing steps that 1) molding sand is dried and then divided into two parts including first molding sand and second molding sand; 2) a sand mold is filled with the first molding sand, and a coolingdevice is embedded in the sand mold; 3) die-casting is performed on a metal plate through a stamping process to form a heat conducting plate matched with the part structure; 4) the heat conducting plate covers the first molding sand of the sand mold; 5) the rest second molding sand is uniformly mixed with a binder, the upper surface of the heat conducting plate is uniformly covered with the mixedsecond molding sand and binder, and a mold cavity is formed through curing; and (6) liquid metal is poured into the mold cavity, after pouring is completed, a water pump is started to pump cooling water into a water guide pipe and a heat dissipation pipe to rapidly discharge heat on the heat conducting plate, and solidification of the liquid metal in the mold cavity is improved.

Description

technical field [0001] The invention relates to a valve pouring molding cooling process. Background technique [0002] Valves play a pivotal role in the entire pipeline. According to the working conditions of the valve, casting and forging molding processes are mainly used. Different molding processes directly affect the service strength of the valve. A good molding process can greatly increase the service life of the valve. [0003] The casting molding process, also known as the pouring molding process, is a method of pouring liquid metal into a mold cavity that is suitable for the shape of the part, and after it is solidified, a part or blank with a certain shape and size of the surface quality is obtained. In this kind of pouring molding process, it takes a long time to wait for the natural cooling and solidification of the metal liquid after pouring is completed. A cooling device is often installed on the mold for rapid cooling, thereby improving processing efficiency. ...
