As the slider 16 moves, the angle changes, and the top plate 18 slides along the circular plate 14 as the connecting rod 17 rotates. At this time, the top plate 18 moves towards the inner wall of the mold sleeve. When the mold sleeve is deviated, the top plate 18 on the deviated side will first contact the mold sleeve and squeeze it to correct the deviation until all the top plates 18 are against the inner wall of the mold sleeve. At this time, the mold sleeve will be fixed and located in the central area of ​​the circular plate 14, realizing the device's rapid positioning of the mold sleeve. When processing the mold sleeve, the circular plate 14 can be driven to rotate with the mold sleeve by the power component to improve the convenience of mold sleeve processing. Through the cooperation of the slider 16 and the connecting rod 17, when the screw 15 rotates, it will transmit power to the top plate 18 through the slider 16 and the connecting rod 17 and make it slide. Then, the top plate 18 squeezes and supports the inner wall of the mold sleeve, realizing the device's rapid positioning of the mold sleeve and improving the convenience of mold sleeve processing and positioning.

[0027] Please see Figure 5As shown, multiple elastic ropes 3 are fixed between adjacent pairs of pressure plates 22; the elastic ropes 3 are located on one side of the top plate 18; by setting the elastic ropes 3, the pressure plates 22 will be in an unfolded state under the elastic force of the spring 23 when working normally, that is, they will be separated from the groove 2. When the pressure plates 22 come into contact with the mold sleeve, they will rotate along the groove 2 and the elastic ropes 3 will be in a stretched state, so that the pressure plates 22 will squeeze the inner wall of the mold sleeve under the elastic force of the spring 23 and the elastic ropes 3, thereby increasing the squeezing effect of the pressure plates 22 on the mold sleeve.

[0028] Please see Figure 5 As shown, a rubber pad 4 is fixedly connected to the middle of the top plate 18; the rubber pad 4 is located between the top plate 18 and the elastic rope 3; by setting the rubber pad 4, when the top plate 18 squeezes the mold sleeve, the rubber pad 4 will contact the mold sleeve before the top plate 18. Because the surface of the rubber pad 4 is a flexible material, when the top plate 18 and the rubber pad 4 come into contact, the rubber pad 4 will disperse the pressure on the inner wall of the top plate 18 and reduce the squeezing effect of the top plate 18 on the inner wall of the mold sleeve.

[0029] Please see Figure 3 As shown, the top of the circular plate 14 is provided with multiple positioning grooves 5; the inner diameter of the positioning grooves 5 is set in equal increments; by setting the positioning grooves 5, since the module of different models of mold sleeves changes in a certain regularity, when positioning different models of mold sleeves, the mold sleeves can be simply positioned by observing the positioning grooves 5, reducing the sliding wear that occurs when the mold sleeves are adjusted on the circular plate 14, and further improving the convenience of mold sleeve positioning.

[0030] Please see Figure 1 and Figure 2 As shown, the power assembly includes a gear 63; the gear 63 and the motor 12 are fixedly connected; the gear 63 and the support 1 are rotatably connected; a cylinder 6 is provided on the top of the support 1; a rack 62 is fixedly connected to the output end of the cylinder 6; the rack 62 and the support 1 are slidably connected; the rack 62 and the gear 63 are meshed; by setting the cylinder 6, when the mold sleeve needs to be rotated, starting the cylinder 6 can push the rack 62 to mesh with the gear 63, thereby causing the gear 63 to drive the motor 12 and the circular plate 14 together with the mold sleeve to rotate, which facilitates the processing of the mold sleeve.

[0031] Working principle: The mold sleeve is placed on top of the circular plate 14. Then, the motor 12 is started, causing the screw 15 to rotate.

The top plate 18 slides along the circular plate 14 as the connecting rod 17 rotates. At this time, the top plate 18 moves towards the inner wall of the mold sleeve. When the mold sleeve is misaligned, the top plate 18 on the misaligned side will first contact the mold sleeve and squeeze it to correct the misalignment. Until all the top plates 18 abut against the inner wall of the mold sleeve, the mold sleeve will be fixed and located in the center area of ​​the circular plate 14, realizing the device's rapid positioning of the mold sleeve. When processing the mold sleeve, the circular plate 14 can be driven by the power component to rotate with the mold sleeve, thereby improving the convenience of mold sleeve processing. When the top plates 18 contact the inner wall of the mold sleeve, the pressure plate 22 will also contact the inner wall of the mold sleeve. The pressure plate 22 will squeeze the inner wall of the mold sleeve under the elastic force of the spring 23, increasing the contact area between the top plates 18 and the inner wall of the mold sleeve. By setting the elastic rope 3, the pressure... When plate 22 is working normally, it will be in an unfolded state under the elastic force of spring 23, that is, it will be disengaged from groove 2. When pressure plate 22 contacts the mold sleeve, it will rotate along groove 2 and stretch elastic rope 3, so that pressure plate 22 will squeeze the inner wall of mold sleeve under the elastic force of spring 23 and elastic rope 3. By setting rubber pad 4, when top plate 18 squeezes mold sleeve, rubber pad 4 will contact mold sleeve before top plate 18. Because the surface of rubber pad 4 is a flexible material, when top plate 18 contacts rubber pad 4, rubber pad 4 will... 4. The pressure on the inner wall of the top plate 18 will be distributed; by setting the positioning groove 5, since the module of different models of mold sleeves changes in a certain regularity, when positioning different models of mold sleeves, the mold sleeves can be simply positioned by observing the positioning groove 5, reducing the sliding wear that occurs when the mold sleeves are adjusted on the circular plate 14; by setting the cylinder 6, when the mold sleeves need to be rotated, starting the cylinder 6 will push the rack 62 to mesh with the gear 63, thereby causing the gear 63 to drive the motor 12 and the circular plate 14 together with the mold sleeves to rotate.
