DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] When implementing: Figure 1-4 As shown, an improved nozzle head for a die-casting machine comprises: a feed pipe 1, a cylindrical ring 12 is fixedly connected to the surface of the feed pipe 1, a conical block 11 is fixedly connected to the end of the feed pipe 1, and a discharge pipe 2 is fixedly connected to the surface of the conical block 11; a material withdrawal mechanism 3, which is arranged inside the feed pipe 1; wherein the material withdrawal mechanism 3 comprises a withdrawal component 31 and a cooling component 32 arranged inside the feed pipe 1, the cooling component 32 is sleeved on the outside of the withdrawal component 31, and the surface of the cooling component 32 extends to the inside of the discharge pipe 2;

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the exit component 31 includes a plurality of interference protrusions 314, which are arranged inside the conical block 11, and the entry groove 311 is opened at the end of the feed pipe 1 away from the ejection pipe 2. A conical groove 312 is opened inside the feed pipe 1, and the conical groove 312 is connected with the entry groove 311. A conical groove 313 is opened inside the conical block 11, and the cross-section of the conical groove 313 is conical, and the conical groove 313 is connected with the conical groove 312. The inner wall of the conical groove 313 is fixedly connected with a plurality of interference protrusions 314, and the plurality of interference protrusions 314 are distributed in a ring shape on the inner wall of the conical groove 313. In the device, when the liquid metal flows into the inside of the feed pipe 1, it enters into the inside of the tapered groove 313 through the conical groove 312. Since the inside of the tapered groove 313 is tapered, the liquid metal in the tapered groove 313 can be more conveniently withdrawn after cooling. The abutment protrusions 314 provided therein can make it easier to produce gaps after the liquid metal hardens, facilitating the withdrawal operation. The number of abutment protrusions 314 is set to an odd number to avoid uniform force on the metal and prevent the metal withdrawal from being affected.

The device cools the interior of the cooling bin 321 through the inlet pipe 325, and at the same time, through multiple outlet pipes 324, the metal liquid at the conical groove 313 is easier to cool. At the same time, the metal can shrink after cooling, which assists the withdrawal operation and avoids the impact of the withdrawal. At the same time, the cooling liquid is introduced into the annular pipe 323 through the connecting pipe 322 and discharged through the discharge pipe 326. The annular pipe 323 can assist in cooling the internal metal of the ejection pipe 2 and cooperate with the withdrawal operation after cooling.
