Description

Technical Field

[0001] This utility model relates to the field of auxiliary casting technology, and more specifically, to an auxiliary casting device for the casting and processing of pump and valve castings. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is processed by grinding and other subsequent means to obtain an object with a certain shape, size and performance. As the core components of fluid transportation and control, the sealing performance, pressure resistance and dimensional accuracy of pump and valve castings directly determine the reliability of equipment operation. Currently, pump and valve castings are mostly cast using the traditional method of "manual mold holding + simple gating". During the casting process, it is necessary to manually hold the crucible and tilt it to pour the molten metal directly into the mold. It is impossible to accurately control the flow rate, and manual casting is inefficient and labor-intensive. Some castings are cast by placing the mold under the gating gate. Each time the mold is changed, it needs to be manually aligned, which is inefficient and inconvenient for automatic alignment and continuous casting. Therefore, an auxiliary casting device for pump and valve casting is proposed. Utility Model Content
