Description

Technical Field

[0001] The invention relates to the field of cooling water drain connection devices, and in particular to a full-diameter quick-change water drain. Background Art

[0002] In the mold cooling system, multiple pipes are required to supply water in different directions for circulation. For the convenience of management, they are generally connected and managed through water drains. The existing water drains are directly connected to a single water pipe through a quick-plug connector. During the disassembly and assembly process, they can only be disassembled and assembled through a single quick-plug connector. In addition, when a single quick-plug connector is damaged, the water pipes can only be removed one by one, and then the water drain is removed. The water drain is generally installed in the equipment, and the machine needs to be disassembled to remove the water drain and replace it with a new one to complete the maintenance, which greatly affects the production efficiency.
