[0021] Embodiment one: please refer to Figures 1-2 The utility model discloses a horizontal split core shooter's mobile limit component, including setting in the core shooter body 1 inside limit component 2.

[0022] In the embodiment,

[0023] It should be noted that,

[0024] Embodiment two: please refer to Figures 1-4 On the basis of embodiment one, the limit component 2 in the embodiment includes mobile platform 21, bottom die 22 and limit piece 23, mobile platform 21 is set in the inside of core shooter body 1, bottom die 22 is slidably arranged on the outside of mobile platform 21, and limit piece 23 is arranged in the inside of core shooter body 1 and is located in the front of mobile platform 21, so as to be used for the mobile limit of bottom die 22.

[0025] The limiting piece 23 comprises a guide rail 231 arranged on the core shooter body 1 and located in front of the moving platform 21, a plurality of sets of clamping teeth 232 are fixedly arranged on the upper surface of the guide rail 231, two sets of adjusting frames 233 are slidingly arranged on the outer side of the guide rail 231, and the adjusting frames 233 are manually slid to the appropriate positions according to the moving range and limiting requirements of the bottom die 22. The adjusting frames 233 move on the guide rail 231 through the sliding structure at the bottom thereof until the predetermined positions are reached, the two sets of adjusting frames 233 are both rotatably provided with shafts 234 at the inner portions thereof, and the outer sides of the two sets of shafts 234 are both fixedly provided with rotating frames 235. The mutually close sides of the two sets of rotating frames 235 are both fixedly provided with limiting columns 236, the upper surfaces of the two sets of adjusting frames 233 are both provided with screw holes 237, the inner portions of the two sets of screw holes 237 are both threadedly connected with bolts 238, the bottom ends of the two sets of bolts 238 are both rotatably provided with fixed teeth 239, and the outer sides of the two sets of bolts 238 are both provided with clamping plates 2310.

[0026] Further, the bolt 238 is rotated, the bolt 238 moves downward through the threaded connection in the screw hole 237 of the adjusting frame 233, and as the bolt 238 moves downward, the fixed teeth 239 at the bottom thereof gradually approach the clamping teeth 232 on the guide rail 231. When the fixed teeth 239 move into between the adjacent two clamping teeth 232, the bolt 238 continues to rotate to push the fixed teeth 239 to be closely engaged with the clamping teeth 232, so as to fix the adjusting frame 233 on the guide rail 231.

[0027] In the embodiment, the height of the adjusting frame 233 is less than the distance between the bottom die 22 close to the inner bottom wall of the core shooter body 1, so that the bottom die 22 can move out when not limited, and the plurality of sets of clamping teeth 232 are arranged at intervals along the length direction of the guide rail 231, so as to lock the position of the adjusting frame 233.

[0028] In the embodiment, the outer sides of the two sets of adjusting frames 233 are both provided with through holes, and the two sets of shafts 234 are both rotatably arranged in the inner portions of the two sets of through holes. The outer side of the limiting column 236 is provided with a buffer sleeve, so as to avoid damage to the bottom die 22 when limited to contact. The width of the fixed teeth 239 is equal to the distance between the adjacent two sets of clamping teeth 232, so as to improve the fixing effect.

[0029] Further, the clamping plate 2310 sleeved on the outer side of the bolt 238 is compressed during the downward movement of the bolt 238 and is fixedly attached to the upper surface of the adjusting frame 233, which further enhances the stability of the adjusting frame 233 and prevents it from loosening during work.

[0030] Further, after the fixing of the adjusting frame 233 is completed, the operator rotates the rotating frame 235, the rotating frame 235 rotates in the adjusting frame 233 through the rotating shaft 234, drives the limiting column 236 to vertically rise from the flat state, after the limiting column 236 rises, the side surface thereof is opposite to the side surface of the bottom die 22, at this time, the clamping plate 2310 plays a limiting role, ensures that the rotating frame 235 cannot continue to rotate after being vertically rotated, thereby maintaining the stable position of the limiting column 236, when the bottom die 22 moves along the moving platform 21, the side surface thereof will contact the limiting column 236.

[0031] Specifically, the limiting column 236 buffers the impact force of the bottom die 22 through the buffer sleeve on the outer side thereof, at the same time, prevents the bottom die 22 from continuing to slide along the moving platform 21, thereby realizing the limiting function of the bottom die 22, when it is necessary to disassemble or maintain the bottom die 22, the operator first reversely rotates the rotating frame 235, drives the limiting column 236 to be flat, because the height design of the adjusting frame 233 is less than the distance between the bottom die 22 close to the inner bottom wall of the core shooting machine body 1, after the bottom die 22 loses the constraint of the limiting column 236, can be smoothly moved out along the moving platform 21, the operator can replace, clean or repair the bottom die 22 and the like.

[0032] It should be noted that when it is necessary to disassemble or maintain the bottom die 22, the operator first reversely rotates the rotating frame 235, drives the limiting column 236 to be flat, because the height design of the adjusting frame 233 is less than the distance between the bottom die 22 close to the inner bottom wall of the core shooting machine body 1, after the bottom die 22 loses the constraint of the limiting column 236, can be smoothly moved out along the moving platform 21, the operator can replace, clean or repair the bottom die 22 and the like.

[0033] The working principle of the above embodiment is as follows:

[0034] Before the normal operation of the core shooting machine, the limiting piece 23 is in the initial state, at this time, the adjusting frame 233 is located at the starting position of the guide rail 231, the bolt 238 is not tightened, the fixing tooth 239 is not engaged with the clamping tooth 232, the rotating frame 235 is in the flat state, the limiting column 236 does not contact the bottom die 22, the bottom die 22 can freely slide on the moving platform 21, the operator manually slides the adjusting frame 233 to the appropriate position according to the moving range and limiting requirement of the bottom die 22, the adjusting frame 233 moves on the guide rail 231 through the sliding structure at the bottom thereof until reaching the predetermined position, rotates the bolt 238, the bolt 238 moves downward through the threaded connection in the screw hole 237 of the adjusting frame 233, as the bolt 238 moves downward, the fixing tooth 239 at the bottom thereof gradually approaches the clamping tooth 232 on the guide rail 231, when the fixing tooth 239 moves into between the adjacent two clamping teeth 232, the bolt 238 continues to rotate, drives the fixing tooth 239 to be closely engaged with the clamping tooth 232, thereby fixing the adjusting frame 233 on the guide rail 231;

[0035] Meanwhile, the clamping plate 2310 sleeved outside the bolt 238 is compressed during the downward movement of the bolt 238, and is fixed on the upper surface of the adjusting frame 233, further enhancing the stability of the adjusting frame 233 and preventing it from loosening during operation. After the fixing of the adjusting frame 233 is completed, the operator rotates the rotating frame 235, and the rotating frame 235 rotates in the adjusting frame 233 through the rotating shaft 234, driving the limiting column 236 to vertically rise from the flat state. After the limiting column 236 rises, its side surface is opposite to the side surface of the bottom die 22. At this time, the clamping plate 2310 plays a limiting role, ensuring that the rotating frame 235 cannot continue to rotate after being vertically positioned, thereby maintaining the stable position of the limiting column 236. When the bottom die 22 moves along the moving platform 21, its side surface will contact the limiting column 236. The limiting column 236 buffers the impact force of the bottom die 22 through the buffer sleeve on its outer side, and at the same time prevents the bottom die 22 from continuing to slide along the moving platform 21, thereby achieving the limiting function of the bottom die 22. When it is necessary to disassemble or maintain the bottom die 22, the operator first reversely rotates the rotating frame 235 to make it drive the limiting column 236 to flatten. Since the height of the adjusting frame 233 is designed to be smaller than the distance between the bottom die 22 close to the inner bottom wall of the core shooter body 1, the bottom die 22 can be smoothly moved out along the moving platform 21 after losing the constraint of the limiting column 236. The operator can perform operations such as replacement, cleaning or maintenance on the bottom die 22.
