[0001] The utility model belongs to the technical field of die-casting machine injection punches, in particular to a single-ring injection punch with a built-in cooling cavity. Background Art

[0002] The die-casting machine is a pressure casting equipment. Its die-casting operation has the advantages of high dimensional accuracy, fast production speed, good mechanical properties of castings, and smooth casting surface. It is generally used for large-scale non-ferrous metal casting. The injection punch is a key component in metal die-casting production. The injection punch cooperates with the melting cup. Its working principle is similar to the push rod and syringe of a syringe. The injection punch pushes the molten alloy liquid into the melting cup, and then quickly presses it into the mold cavity, and maintains the set pressure for a period of time until the casting is finally cooled and formed before entering the next injection cycle.

[0003] In the prior art, the shot head needs to withstand high temperatures during die casting, but it cannot lower the temperature on its own. After long-term use, the shot head will be damaged due to excessive temperature. In addition, the installation and disassembly of the shot head is troublesome and inconvenient for the staff to disassemble. As a result, when the shot head is damaged and needs to be replaced, too much time is wasted, thereby reducing the work efficiency of the staff in repairing the shot head.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
