Although this method could complete the welding task, the efficiency was low and the welding quality was unstable. With the development of welding technology, equipment such as arc welding and argon arc welding was introduced, significantly improving the welding precision and efficiency. In order to adapt to these new devices, the mold design began to pay more attention to the shape of the welding joint and the control of the welding process. For example, more precise positioning devices and jigs were adopted. With the progress of industrial automation, the welding mold also began to be combined with the robot welding system to achieve automated production, improving the production efficiency and the consistency of welding quality. The composition structure of the welding mold for brass blocks and braided wires includes a mold body, a positioning block, a reaction chamber, a cooling channel, a forming cavity, etc. However, in the process of using an existing welding mold for brass blocks and braided wires, problems such as welding through, melting of the corners due to too high temperature of the solder joints, and insecure welding are likely to occur. Therefore, the above technical problems need to be solved. Summary of the Utility Model
