[0018] 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.
[0019] Reference Figure 1 - Figure 2, the utility model provides an embodiment: a rotary screw removal mold, including a fixed column 1, the external bottom side of the fixed column 1 is provided with an external thread 2, and the fixed column 1 is positioned in a fixed position by means of the external thread 2, and a fixed sleeve 3 is fixedly connected to the external middle side of the fixed column 1, and the fixed sleeve 3 is designed here to make the fixed column 1 more stable and to play a certain protective role, a reinforcement plate 4 is fixedly connected to the outside of the fixed column 1, and an external thread 2 5 is provided on the outside of the fixed column 1, and the fixed column 1 is relatively displaced by means of the external thread 2 5, and an external thread 3 6 is provided on the external top side of the fixed column 1, and a sliding column 7 is fixedly connected to the top of the fixed column 1, and a sliding sleeve 8 is slidably connected to the outside of the sliding column 7, and a spring 10 is provided inside the sliding sleeve 8;
[0020] A limiting assembly is arranged inside the sliding sleeve 8, and the limiting assembly includes a limiting plate 9. The outside of the limiting plate 9 is slidably connected to the inside of the sliding sleeve 8. The limiting plate 9 is designed here to prevent the sliding sleeve 8 from slipping off to the outside of the sliding column 7. The external thread of the fixed column 1 is connected to the outer shell 11. It is designed here that the fixed column 1 can be relatively displaced by rotating the outer shell 11. A plurality of racks 12 are fixedly connected to the outside of the outer shell 11. An outer mold 13 is fixedly connected to the top of the outer shell 11. Positioning blocks 14 are fixedly connected to the left and right sides of the outer mold 13. The positioning blocks 14 are designed here to position the fixed column 1 so that the workpiece can be accurately ejected.
[0021] Reference Figure 1 - Figure 3 The bottom of the limit plate 9 is fixedly connected to the top of the sliding column 7, and the outside of the sliding sleeve 8 is slidably connected to the inside of the outer mold 13. It is designed here that the workpiece can be ejected by the displacement of the sliding sleeve 8. The external top side of the fixed column 1 is threadedly connected to the inside of the outer mold 13. One end of the spring 10 is fixedly connected to the internal top side of the sliding sleeve 8, and the other end of the spring 10 is fixedly connected to the top of the limit plate 9. It is designed here that the compression and rebound of the spring 10 can protect the workpiece when it is ejected, thereby preventing the workpiece from wear and deformation.
[0022] Working principle: when it is necessary to remove the workpiece inside the mold, first fix the fixing column 1 at the specified position through the external thread 2, and then the rack 12 can be meshed with the external gear, so that the rack 12 and the outer shell 11 can rotate, and then the fixing column 1 can be driven to rotate, and as the fixing column 1 rotates, the fixing column 1 will be displaced relative to the outer shell 11, and then the sliding sleeve 8 will be the first to contact the workpiece. At this time, the fixing column 1 is positioned by the positioning block 14, and the sliding sleeve 8 will be squeezed at this time, and the spring 10 will be compressed and rebounded. At this time, the elastic force of the spring 10 will be used to buffer the workpiece when it is ejected, thereby effectively protecting the workpiece.
[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
