After the user installs the lower mold 5 on the surface of the sliding rod 4, the corresponding number of middle molds 6 are installed according to actual use requirements, and then the upper mold 7 is installed. After the upper mold 7 is installed, the limiting ring 8 is sleeved on the surface of the sliding rod 4, so that the first plug rod 11 passes through the first plug hole 9 and the first through hole 10, and then the second plug rod 13 is inserted into the second through hole 12 to fix the position of the limiting ring 8. The limiting ring 8 squeezes the lower mold 5, the middle mold 6 and the upper mold 7 so that the lower mold 5, the middle mold 6 and the upper mold 7 are tightly fitted to each other to prevent gaps from occurring during casting. By controlling the number of middle molds 6, the user can conveniently adjust the number of notches according to processing requirements.

[0024] Reference Figure 3 As shown, in this embodiment: the front end and the rear end of the first plug rod 11 are both provided with a second plug hole 15, the interior of the second plug hole 15 is slidably connected with a third plug rod 17, the surface of the second plug rod 13 is provided with a third through hole 16 used in conjunction with the third plug rod 17, and the end of the third plug rod 17 away from the first plug rod 11 is fixedly connected with a control block 18. When the second plug rod 13 is inserted into the inner diameter of the second through hole 12, the position of the second plug rod 13 is limited by the connection between the third plug rod 17 and the second plug hole 15 and the third through hole 16, so as to prevent the second plug rod 13 from being separated from the inner diameter of the second through hole 12.

[0025] Reference Figure 3 As shown, in this embodiment: a tension spring 19 is sleeved on the surface of the third plug rod 17, and the end of the tension spring 19 close to the control block 18 is fixedly connected to the control block 18, and the end of the tension spring 19 away from the control block 18 is fixedly connected to the first plug rod 11. When the third plug rod 17 is inserted into the second socket 15 through the third through hole 16, the tension force generated by the tension spring 19 limits the position of the control block 18 to prevent the control block 18 from driving the third plug rod 17 to detach from the second socket 15.

[0026] Reference Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment: a pull rod 20 is fixedly connected to one side of the first slider 3, a shell 21 is fixedly connected to both sides of the base 1, an insert block 22 is slidably connected inside the shell 21, a fixed block 23 used in conjunction with the insert block 22 is fixedly connected to both sides of the base 1, a control rod 24 is fixedly connected to the surface of the insert block 22, and a limiting groove 25 used in conjunction with the control rod 24 is provided on the side of the shell 21 away from the base 1. After the first slider 3 is pushed to the innermost part of the first slide groove 2 by the pull rod 20, the insert block 22 is driven by the control rod 24 to be inserted into the interior of the fixed block 23, so that the insert block 22 limits the position of the pull rod 20 to prevent the pull rod 20 from moving and causing a gap between the two lower molds 5.

[0027] Reference Figure 5 As shown, in this embodiment: the rear end of the plug block 22 is fixedly connected to a spring 26, and the other end of the spring 26 is fixedly connected to the inner wall of the shell 21. When the plug block 22 is inserted into the interior of the fixed block 23, the thrust generated by the spring 26 prevents the plug block 22 from being separated from the inner diameter of the fixed block 23.

[0028] Reference Figure 4 As shown, in this embodiment: the front end and the rear end of the first slider 3 are fixedly connected to the second slider 27, and the front end and the rear end of the inner cavity of the first slide groove 2 are provided with a second slide groove 28 used in conjunction with the second slider 27. Through the coordinated use of the second slider 27 and the second slide groove 28, the first slider 3 is more stable when moving.

[0029] Reference Figure 6 As shown, in this embodiment: the top and bottom of the inner cavity of the shell 21 are fixedly connected with a third slider 29, and the top and bottom of the plug block 22 are provided with a third slide groove 30 used in conjunction with the third slider 29. Through the sliding connection between the third slider 29 and the third slide groove 30, the movement of the plug block 22 is guided to prevent the plug block 22 from being offset when moving.

[0030] The practical working principle of the present invention is as follows: after the user installs the lower mold 5 on the surface of the slide bar 4, the corresponding number of middle molds 6 are installed according to actual use requirements, and then the upper mold 7 is installed. After the upper mold 7 is installed, the limiting ring 8 is sleeved on the surface of the slide bar 4, so that the first plug rod 11 passes through the first plug hole 9 and the first through hole 10, and then the second plug rod 13 is inserted into the second through hole 12 to fix the position of the limiting ring 8. The limiting ring 8 squeezes the lower mold 5, the middle mold 6 and the upper mold 7 so that the lower mold 5, the middle mold 6 and the upper mold 7 are closely fitted to each other to prevent gaps from occurring during casting. By controlling the number of the middle mold 6, the user can conveniently adjust the number of notches according to processing requirements. When the second plug rod 13 is inserted into the inner diameter of the second through hole 12, the third plug rod 17 and the second plug hole 1 5 and the third through hole 16 are plugged into each other to limit the position of the second plug rod 13 to prevent the second plug rod 13 from being disengaged from the inner diameter of the second through hole 12. When the third plug rod 17 is inserted into the second plug hole 15 through the third through hole 16, the tension generated by the tension spring 19 limits the position of the control block 18 to prevent the control block 18 from driving the third plug rod 17 to be disengaged from the inside of the second plug hole 15. After the first slider 3 is pushed to the innermost part of the first slide groove 2 by the pull rod 20, the control rod 24 drives the plug block 22 to be inserted into the inside of the fixed block 23, so that the plug block 22 limits the position of the pull rod 20 to prevent the pull rod 20 from moving and causing a gap between the two lower molds 5. When the plug block 22 is inserted into the inside of the fixed block 23, the thrust generated by the spring 26 prevents the plug block 22 from being disengaged from the inner diameter of the fixed block 23.
