[0020] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model.

[0021] See also Figure 1-4The utility model provides a technical solution: a core-pulling locking structure in a slider in a plastic mold, comprising a first template 1, a second template 2 is arranged on one side of the first template 1, the first template 1 and the second template 2 cooperate with each other to play the role of injection molding, and cavities are provided inside the first template 1 and the second template 2. A slider 3 is movably provided at the top position in the first template 1, and the slider 3 is used to play the role of stripping. A guide groove 4 is provided at the bottom position in the slider 3, and the guide groove 4 is used to cooperate with a guide column 12. A limiting groove 5 is provided on one side of the slider 3, and the limiting groove 5 is used to play the role of limiting. A through groove 6 is provided on one side of the first template 1, and a corresponding component is arranged in the through groove 6. A limiting clamping ball 7 is provided at one side of the through groove 6, and the limiting clamping ball 7 is used to be clamped with the limiting groove 5.

[0022] Furthermore, the first template 1 and the second template 2 are in contact with each other, and the interiors of the first template 1 and the second template 2 are interconnected, wherein this design facilitates processing between the two.

[0023] Furthermore, a guide column 12 is fixedly provided at a top position on one side of the second template 2, and one end of the guide column 12 extends into the interior of the guide groove 4 and is movably connected to the guide groove 4, wherein the guide column 12 is used in conjunction with the guide groove 4 to play a guiding role.

[0024] Furthermore, one end of the limit locking ball 7 extends to the inside of the through groove 6 and contacts the slider 3 , and the limit locking ball 7 is adapted to the limit groove 5 , wherein the limit locking ball 7 can be engaged with the limit groove 5 to limit the slider 3 .

[0025] Furthermore, a connecting frame 8 is fixedly disposed on one side of the through slot 6 , and sliding grooves 9 are provided on the front and rear surfaces of the connecting frame 8 , wherein the through slot 6 is used to arrange corresponding components.

[0026] Furthermore, guide blocks 10 are fixedly provided on the front and rear surfaces of the limit ball 7, and the opposite sides of the two guide blocks 10 extend into the interior of the slide groove 9 and contact the inner wall of the slide groove 9. The guide blocks 10 are slidingly connected to the slide groove 9, wherein the setting of the guide blocks 10 and the slide groove 9 facilitates the limiting of the limit ball 7.

[0027] Furthermore, a return spring 11 is fixedly provided on one side of the connecting frame 8 , and one end of the return spring 11 is fixedly connected to the limit locking ball 7 , wherein the return spring 11 can drive the limit locking ball 7 to move.

[0028] Working principle: When using this device, when the first template 1 and the second template 2 are separated, the guide column 12 is continuously moved out of the guide groove 4 in the slider 3, causing the slider 3 to gradually lose its limit position. In this way, when the slider 3 loses its limit position and drives the material to be demolded, the slider 3 will move downward, and the movement of the slider 3 will drive the limit groove 5 to move. When the limit groove 5 moves to align with the limit ball 7 in the through groove 6, the limit ball 7 will extend under the push of the reset spring 11, thereby engaging with the limit groove 5 and locking the slider 3.

[0029] According to the above working process, we can know:

[0030] The core-pulling locking structure in the slider in the plastic mold is provided with a limit groove 5, a limit ball 7, a reset spring 11 and a through groove 6, so that when the device is in use, a snap-on design can be used to limit the slider 3, thereby maintaining the stability of the slider 3 when it is limited. In addition, the slider 3 of the device adopts a self-limiting design, which is convenient for users to use, brings convenience to users, improves the practicality of the device, and meets the user's usage needs.
