[0020] Reference Figure 1-3 An online rotating die head at any angle is disclosed, comprising an extrusion tube 1, a connecting sleeve 2, and a die head body 3. The connecting sleeve 2 is fixedly installed on one end of the extrusion tube 1. The die head body 3 and the connecting sleeve 2 are in a sliding fit. An arc-shaped slide bar 201 is fixedly connected to the outer periphery of the connecting sleeve 2, and an arc-shaped groove 300 is correspondingly formed on the inner periphery of the die head body 3. The arc-shaped slide bar 201 and the inner side of the arc-shaped groove 300 form a sliding fit structure. When the die head body 3 rotates, the arc-shaped slide bar 201 slides on the inner side of the arc-shaped groove 300, facilitating smoother rotation.

[0021] In this embodiment, refer to Figure 3 A positioning mechanism is also provided between the die head body 3 and the connecting sleeve 2; including positioning grooves 200 symmetrically opened on both sides of the extrusion tube 1, and a clearance channel opened at one end of the positioning groove 200 on both sides of the connecting sleeve 2, extending to the inner side of the die head body 3. A positioning block 4 is inserted and limited inside the positioning groove 200, and the positioning block 4 and the inner side of the clearance channel form a sliding fit structure. A positioning pull rod 5 is fixedly connected to one end of the positioning block 4. A circular hole channel is opened at the adjacent end of the clearance channel. Multiple circular hole channels and clearance channels extending to the inner side of the die head body 3 are evenly distributed. One end of the positioning pull rod 5 passes laterally through the inner side of the circular hole channel and extends to the outside of the die head body 3. An adjusting block 6 is fixedly installed at the end of the positioning pull rod 5 located outside the die head body 3. A positioning spring 7 is provided inside the clearance channel. The positioning spring 7 is sleeved on the outer wall of the positioning pull rod 5. One end of the positioning spring 7 is fixedly connected to the side wall of the positioning block 4, and the other end of the positioning spring 7 is fixed to the inner end wall of the clearance channel.

[0022] It should be noted that when not rotating, the positioning block 4 is inserted into the inner side of the positioning groove 200. It can be moved upward by the T-shaped operating rod 10, which drives the crossbar 9 and the slider 8 to move upward along the inner wall of the relief groove 301. This causes the bottom end of the T-shaped operating rod 10 to move upward away from the inner side of the limiting groove 600. After releasing the limiting of the adjusting block 6, the positioning spring 7 is subjected to the elastic force to reset, which drives the positioning block 4 to move towards the inner side of the positioning groove 200 until the positioning block 4 is completely inside the positioning groove 200. When it is necessary to rotate the angle of the mold head body 3, the adjusting block 6 is pulled first, which drives the positioning pull rod 5 and the positioning block 4 to move outward, so that the positioning block 4 moves to the inner side of the relief channel opened in the mold head body 3, away from the inside of the connecting sleeve 2. The positioning block 4 then compresses the positioning spring 7 to deform it.

[0023] In this embodiment, refer to Figure 4 A limiting groove 600 is provided on the top of the adjusting block 6. A relief groove 301 is provided on the side wall of the mold head body 3 above the adjusting block 6. A slider 8 is slidably connected inside the relief groove 301. A crossbar 9 is fixedly connected to the outer end of the slider 8. A T-shaped operating rod 10 is fixedly connected to one end of the crossbar 9. The bottom end of the T-shaped operating rod 10 is inserted into the inner side of the limiting groove 600. A return spring 11 is provided inside the relief groove 301. The upper end of the return spring 11 is fixedly connected to the upper inner wall of the relief groove 301, and the lower end of the return spring 11 is fixedly connected to the top surface of the slider 8.

[0024] It should be noted that when the mold head body 3 is not positioned with the connecting sleeve 2, the limiting groove 600 is directly below the T-shaped operating rod 10. The elastic reset action of the reset spring 11 drives the slider 8 to move downward along the inner side of the relief groove 301, so that the bottom end of the T-shaped operating rod 10 is inserted into the inner side of the limiting groove 600, thereby limiting the adjustment block 6.

[0025] In this embodiment, refer to Figure 1 The upper sides of the outer wall of the mold head body 3 are symmetrically provided with arc-shaped grooves 302.

[0026] It should be noted that the arc-shaped groove 302 facilitates rotational operation.

[0027] The working principle of this utility model is as follows: In use, the die head body 3 is first fitted onto the outer wall of the connecting sleeve 2, and the arc-shaped slide groove 300 is fitted against the inner side of the arc-shaped slide bar 201. When not rotating, the positioning block 4 is inserted into the inner side of the positioning groove 200. The T-shaped operating rod 10 can be moved upwards, driving the crossbar 9 and the slider 8 to move upwards along the inner wall of the relief groove 301, causing the bottom end of the T-shaped operating rod 10 to disengage from the inner side of the limiting groove 600. After releasing the limiting effect on the adjusting block 6, the positioning spring 7 is subjected to a spring force to reset, causing the positioning block 4 to move towards the inner side of the positioning groove 200 until the positioning block 4 is completely located inside the positioning groove 200. When it is necessary to rotate the angle of the die head body 3, first pull the adjusting block 6 to drive the positioning pull rod. 5 and positioning block 4 move outward, so that positioning block 4 moves to the inside of the clearance channel opened in the die head body 3, away from the inside of the connecting sleeve 2, and the positioning spring 7 is squeezed by positioning block 4 to deform it. At this time, the limiting groove 600 is directly below the T-shaped operating rod 10. The elastic restoring action of the return spring 11 drives the slider 8 to move downward along the inside of the clearance groove 301, so that the bottom end of the T-shaped operating rod 10 is inserted into the inside of the limiting groove 600, thereby limiting the adjustment block 6. After the positioning between the die head body 3 and the connecting sleeve 2 is completed, the die head body 3 can be rotated at any angle through the arc groove 302. After rotation, the above steps are repeated to achieve the positioning of the extrusion tube 1.

[0028] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
