Pipe valve shell casting cooling device

Abstract

The invention relates to a pipe valve shell casting cooling device. The device comprises a bearing table, a cooling cavity used for cooling a pouring bottom die, a water tank used for transferring andstoring cooling water, a water inlet chamber used for storing the cooling water and a water outlet chamber used for collecting residual water. The cooling cavity, the water tank, the water inlet chamber and the water outlet chamber are all erected on the bearing table, wherein the number of the cooling cavities is at least one, and a pouring bottom die is installed in the cooling cavity. The device can be applied to the casting process of a pipe valve shell; the cooling water circulation is adopted for cooling treatment, so the continuous cooling state of the cooling cavity can be ensured. According to the invention, the modes of pre-cooling, total conveying, graded conveying and residual water recycling are adopted for cooling the pouring bottom die which is produced at the same time, thereby guaranteeing that a casting part can be rapidly cooled, demolding treatment can be conveniently conducted on the casting part, and the production efficiency of casting of the pipe valve shell isimproved.

Description

technical field [0001] The invention relates to the technical field of casting cooling devices, in particular to a casting cooling device for pipeline valve shells. Background technique [0002] Casting is a kind of metal thermal processing technology mastered by human beings earlier, and the technology has reached a very high level. Casting is to pour liquid metal into the casting cavity that is suitable for the shape of the part, and after it is cooled and solidified, the parts are obtained. In the method of casting or blank, the material to be cast is mostly metal that is originally solid but heated to liquid state, and the material of the mold can be sand, metal or even ceramics. [0003] In the process of manufacturing the pipeline valve shell, when the pouring material is poured into the mold, the mold needs to be cooled rapidly, so that the castable material can be cooled rapidly to fix the mold, but in the current process of casting the pipeline valve shell In the p...

Problems solved by technology

[0003] In the process of manufacturing the pipeline valve shell, when the castable is poured into the mold, the mold needs to be cooled rapidly, so that the castable can be cooled rapidly to fix the mold, but in the current process of casting the pipeline valve shell In the process, the cooling efficiency of the cold room equipment used is low, and multiple cast mold groups cannot be cooled at the same time. If the cooling is not timely, it is easy to cause the castings to be difficult to demould
