[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] According to the duckbill short tube positioning shaping mold of the embodiment of the utility model, Figure 1 and Figure 2 As shown, it includes a lower template 10, an arc-shaped top block 20 and an upper template; the lower template 10 is provided with a first positioning protrusion 11 and a first positioning plane 12; the arc-shaped top block 20 has a connecting end and a top block end, and the connecting end of the arc-shaped top block 20 is connected to the inner side of the first positioning protrusion 11; the upper template 30 is provided with a second positioning protrusion 31 and a second positioning plane 32; wherein the duckbill short tube has an end to be shaped and a duckbill arc end; the duckbill short tube is arranged in the first positioning plane 12, and the top block end of the arc-shaped top block 20 abuts against the duckbill arc end of the duckbill short tube; the second positioning protrusion 31 of the upper template 30 matches the shape of the first positioning plane 12 of the lower template 10; the second positioning plane 32 of the upper template 30 matches the shape of the first positioning protrusion 11 of the lower template 10; the upper template 30 Moving horizontally downward, the second positioning protrusion 31 abuts against the first positioning plane 12 and fixes the duckbill short tube between the lower template 10 and the upper template 30; the extrusion equipment extrude the end of the duckbill short tube to be shaped, the lower template 10 and the upper template 30 are used to laterally fix the duckbill short tube, and the arc-shaped top block 20 is used to fix the duckbill arc end of the duckbill short tube. During operation, due to its tubular structure, the lower template 10 and the upper template 30 are not to damage the outer shape of the duckbill short tube, so the inner side is consistent with the outer shape of the duckbill short tube and is arc-shaped. During the extrusion and shaping process, the lower template 10 and the upper template 30 can prevent the duckbill short tube from lateral movement, but cannot prevent the duckbill short tube from rotating. Therefore, the arc-shaped top block 20 abuts and fixes the duckbill arc end at the rear end of the duckbill short tube to avoid rotation of the duckbill short tube.

[0023] When implementing it, Figure 3 As shown, the duckbill short tube positioning and shaping mold also includes an adjusting fixing pin 40, and there are multiple adjusting fixing pins 40. The multiple adjusting fixing pins 40 are all arranged on the first positioning protrusion 11 to fix the arc-shaped top block 20. At the same time, the multiple adjusting fixing pins 40 can adjust the position of the arc-shaped top block 20 according to different duckbill short tube lengths and tube diameters.

[0024] When implementing it, Figure 3 and Figure 4 As shown, a top block groove 111 is provided on the first positioning protrusion 11 ; the connecting end of the arc-shaped top block 20 is fixed in the top block groove 111 through a plurality of adjustment fixing pins 40 .

[0025] When implementing it, Figure 3 and Figure 4 As shown, a first fixing groove 121 is provided on the first positioning plane 12, and the first side of the duckbill short tube abuts against the first fixing groove 121. The shape of the first fixing groove 121 and the shape of the first side of the duckbill short tube are both arc-shaped. Therefore, the first side of the duckbill short tube can abut against the first fixing groove 121 as a whole to laterally fix the duckbill short tube so that it will not shift during extrusion molding.

[0026] When implementing it, Figure 5 and Figure 6 As shown, a second fixing groove 311 is provided on the second positioning protrusion 31, and the second side of the duckbill short tube abuts against the second fixing groove 311. The shape of the second fixing groove 311 and the shape of the second side of the duckbill short tube are both arc-shaped. Therefore, the second side of the duckbill short tube can abut against the second fixing groove 311 as a whole to laterally fix the duckbill short tube so that it will not shift during extrusion molding.

[0027] When implementing it, Figure 7 As shown, the top block end of the arc-shaped top block 20 matches the shape of the duckbill arc end of the duckbill short tube. The matching arc shape ensures that the duckbill arc end of the duckbill short tube will not rotate after being abutted and fixed by the top block end of the arc-shaped top block 20.

[0028] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
