Description

Technical Field

[0001] The utility model relates to the technical field of advanced manufacturing and automation, in particular to a casting device for gate valve production. Background Art

[0002] The gate valve is an opening and closing part, the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate. Usually the sealing surface is welded with metal materials to increase wear resistance. Most of the gate valve shells are cast during production, which makes operation more convenient and can make good use of materials.

[0003] In the casting process of gate valves, sand molds are indispensable auxiliary tools, and their importance is self-evident. However, the design of traditional sand boxes is often relatively simple, and adopts an integral structure. When this design is damaged, it often requires overall replacement, which greatly limits the convenience of disassembly and maintenance. After the casting is completed, the sand box is extremely difficult to move due to its own bulkiness, which not only increases the physical burden of the operator, but also reduces work efficiency. At the same time, the traditional sand box lacks sufficient consideration of the cooling mechanism in its design, resulting in a long cooling time for the casting molded parts, which in turn slows down the overall production rhythm and reduces production efficiency. Therefore, it is necessary to design a casting device for gate valve production. Utility Model Content
