[0017] 1. Injection rod; 2. Water delivery pipe; 3. Ring seat; 4. Filling hole; 5. Head ring; 6. Middle ring; 7. Tail ring; 8. Connecting head. Specific Embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0019] Referring to Figure 1 , the three-ring head-ring aluminum liquid filling punch structure in the embodiment of the present invention includes an injection rod 1. A water delivery pipe 2 is arranged inside the injection rod 1. A connecting head 8 is arranged at one end of the injection rod 1. A ring seat 3 is arranged at the outer end of the connecting head 8. A filling hole 4 is arranged on the outer surface of the front end of the ring seat 3. A head ring 5 is arranged at the inner end of the ring seat 3. A middle ring 6 is arranged at one end of the head ring 5. A tail ring 7 is arranged at one end of the middle ring 6. A connecting head 8 is arranged at one end of the tail ring 7.

[0020] The injection rod 1 is made of high-strength alloy steel and its surface is hardened. The interior of the injection rod 1 is in a positioning contact state with the water delivery pipe 2. The connecting head 8 is threadedly connected to one end of the injection rod 1. By providing the connecting head 8, stability can be provided for the connection between the tail ring 7 and the injection rod 1. The outer side of the front end of the ring seat 3 is threadedly connected to the connecting head 8. The outer surface of the front end of the ring seat 3 is in a fitting and communicating connection with the filling hole 4. A mechanical connection is formed between the inner end of the filling hole 4 and the head ring 5. By providing the filling hole 4, the molten aluminum can quickly fill the mold cavity to complete casting. The head ring 5 adopts an open structure. The head ring 5 is in a mechanical threaded connection with the outer peripheral surface of the ring seat 3. By providing the head ring 5, the flow of the molten aluminum can be guided and controlled to ensure the uniformity of the filling of the molten aluminum inside the mold, reducing air holes and defects.
