[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0021] Please refer to Figures 1 - 3, which is the first embodiment of the present utility model. This embodiment provides an extrusion die structure for a material distribution channel, including a die core 2, a machine head outer cylinder 1 sleeved on the die core 2. The die core 2 and the machine head outer cylinder 1 cooperate. A feed hole 11 is opened at the top of the machine head outer cylinder 1 for feeding through the feed hole 11. A material distribution groove 21 corresponding to the feed hole 11 is opened on the die core 2, and material distribution channels symmetrically distributed are arranged on the die core 2. The material distribution channels are communicated with the material distribution groove 21. A protective component is arranged on the machine head outer cylinder 1. The protective component includes a dust-proof plug 5 and a sealing sleeve 6 sleeved on the dust-proof plug 5, realizing the addition of the sealing sleeve 6. When the lower part of the dust-proof plug 5 is inserted into the interior of the feed hole 11, the sealing sleeve 6 fits against the inner wall of the feed hole 11. By the fitting of the sealing sleeve 6 and the feed hole 11, the dust-proof plug 5 is inserted more tightly into the feed hole 11, increasing the protective effect of the feed hole 11 and preventing impurities from entering through the feed hole 11.

[0022] In this embodiment, preferably, a material discharging support base 4 is further installed at the top of the machine head outer cylinder 1, realizing the addition of the material discharging support base 4. A support plate 7 is arranged at the inner bottom of the material discharging support base 4, realizing the addition of the support plate 7. When using the feed hole 11, the dust-proof plug 5 is pulled out from the feed hole 11 and inserted into the material discharging support base 4, and is placed on the support plate 7, increasing the performance of restricting the removed dust-proof plug 5.

[0023] In this embodiment, preferably, symmetrically distributed rubber strips 41 are arranged on the inner side surface of the material discharging support base 4, realizing the addition of the rubber strips 41. The rubber strips 41 abut against the support plate 7. When the support plate 7 is placed, the added support plate 7 is reinforced by the extrusion of the two rubber strips 41.

[0024] In this embodiment, preferably, symmetrically distributed convex handles 71 are arranged at the top of the support plate 7, and the convex handles 71 are of a cuboid structure, increasing the efficiency of pulling out and removing the support plate 7 through the cuboid convex handles 71.

[0025] In this embodiment, preferably, an annular die orifice 3 is further installed on the machine head outer cylinder 1 at the discharging end of the die core 2, realizing the addition of the annular die orifice 3. A marking material hole 31 is opened at the top of the annular die orifice 3, and the lower end of the marking material hole 31 is directly opposite to the die core 2. In this way, the flowing material for marking the pipe fittings can enter through the marking material hole 31 and combine with the pipe fittings, realizing stable identification of the product. Embodiment
