DETAILED DESCRIPTION

[0019] Embodiment 1

[0020] like Figure 1-Figure 5 As shown, the utility model proposes a detachable die-casting machine material tube, including a tube body 1, a heat-insulating sleeve 2 is provided in the middle of the tube body 1, one end of the tube body 1 is connected to a fixing ring 3, and the other end is connected to a connecting ring 4, a positioning piece is provided between the connecting ring 4 and the fixing ring 3, a limiting component cooperating with the connecting ring 4 is provided on the fixing ring 3, and a pressing component for driving the limiting component to limit the connecting ring 4 is provided on the outer side of the fixing ring 3.

[0021] Among them, the limiting assembly includes a slide plate 7, a plug post 8, a support spring 9 and a hemispherical block 10. The outer circumference of the fixed ring 3 is provided with a plurality of evenly distributed grooves 11. The slide plates 7 are slidably arranged in the plurality of grooves 11. The slide plates 7 are connected with the plug posts 8. A support spring 9 sleeved on the outside of the plug posts 8 is connected between the slide plate 7 and the groove wall of the groove 11. One end of the plug post 8 extends to the inner side of the fixed ring 3, and the other end is connected to the hemispherical block 10. A through hole communicating with the groove 11 is provided on the inner surface wall of the fixed ring 3. The plug post 8 extends to the inner side of the fixed ring 3 through the through hole. In the absence of external force, the end of the plug post 8 is located on the inner side of the groove 11 under the action of the support spring 9.

[0022] Furthermore, a plurality of insertion holes 12 corresponding to the insertion posts 8 are provided in the middle of the connecting ring 4 , and the insertion posts 8 enter the insertion holes 12 under the action of the pressure force, thereby limiting the connection ring 4 .

[0023] Among them, the pressing assembly includes a worm wheel 13, a mounting plate 14, a worm 15 and a handle 17. The worm wheel 13 is rotatably arranged on the outside of the fixing ring 3. The worm wheel 13 is provided with a plurality of oblique guide grooves 16 corresponding to the grooves 11. Two groups of mounting plates 14 are provided, both of which are installed on the fixing ring 3. The worm 15 is rotatably arranged between the two mounting plates 14. The worm 15 is meshed and connected with the worm wheel 13. One end of the worm 15 passes through the corresponding mounting plate 14 and is connected to the handle 17.

[0024] The working principle of the utility model is as follows: when in use, first insert the connecting ring 4 at the end of the tube body 1 on the adjacent side into the inner side of the fixing ring 3, and then turn the handle 17, the handle 17 drives the worm 15 to rotate, because the worm 15 and the worm wheel 13 are in a meshing state, the worm wheel 13 will rotate with the rotation of the worm 15, and during the rotation process, the groove wall of the oblique guide groove 16 will push the hemispherical block 10, and the hemispherical block 10 drives the slide plate 7 to compress the support spring 9 under the action of the extrusion force, so that the end of the plug column 8 passes through the fixing ring 3 and is in contact with the insertion hole 12 on the connecting ring 4 In the plug-in state, the assembly of the material pipe is completed. When disassembly is required, the handle 17 is rotated in the opposite direction, that is, the worm gear 13 is driven by the worm 15 to rotate in the opposite direction around the fixed ring 3. During the reverse rotation, the groove wall of the oblique guide groove 16 removes the pressure on the hemispherical block 10. At this time, the support spring 9 releases the elastic potential energy to drive the slide plate 7 to reset. The reset of the slide plate 7 further drives one end of the plug column 8 to disengage from the socket 12. At this time, the disassembly between the adjacent tube bodies 1 is completed. The overall disassembly and assembly is convenient, and one person can operate it, avoiding unnecessary waste of human resources.
