[0010] Preferably, the surface of each cylinder fixing block is equipped with a positioning block for positioning and assembling the cylinder body, and the surface of each slider fixing seat is provided with a positioning slot, and the positioning slot and the surface of the positioning block are engaged with each other.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the spinal core pulling multiple core pulling structure not only makes it convenient for users to assemble the cylinder body on the surface of the cylinder fixing block, making the core pulling structure more convenient for users to operate, but also helps to reduce human intervention, speed up the production pace, improve overall work efficiency, reduce unnecessary energy consumption, and minimize wear on molds and other equipment, thus extending the service life of the equipment.

[0012] 1. With a convenient assembly mechanism, the cylinder fixing block drives the positioning block to automatically engage with the corresponding positioning slot. Under the engaging action of the positioning slot and the positioning block, the cylinder body is positioned and assembled. Then, the user tightens the fastening bolts on the surface of the screw hole. With the thread engagement between the screw hole and the fastening bolt, the cylinder body and the cylinder fixing block are assembled on the surface of the slider fixing seat.

Since the wire rope body is fixed to the wire rope adjusting block, and the adjusting block, along with the spring, is fixed to the slider seat with limit screws, when the slider seat moves, the first, second, and third vertebral inserts move synchronously under the action of the wire rope body. While the slider seat moves the relevant parts, the seat body and the guide strip fixed to the seat body surface by fastening screws remain stationary. This stationary movement is determined by the stroke control rod and the stroke fixing block. Since the stroke fixing block is engaged with the positioning block, and the positioning block is fixed to the slider fixing seat... Under the action of the limiting block, the seat body always maintains a certain distance from the slider seat. The trajectory of the spine block is determined by the guide bar. When the spine block moves into a straight line, the slider seat just touches the seat body. At the same time, the groove on the positioning block just reaches the position of the stroke fixing block. The stroke fixing block moves upward and disengages from the surface of the positioning block. The seat body moves backward together with the slider seat, realizing the function of multiple core pulling. This makes the core pulling structure help reduce human intervention, speed up the production rhythm, improve the overall work efficiency, reduce unnecessary energy consumption, and minimize wear on molds and other equipment, thus extending the service life of the equipment.

[0025] Furthermore, such as Figure 4and Figure 8 As shown, the surfaces of the slider fixing seat 101 and the cylinder fixing block 105 are provided with a convenient assembly mechanism 3. The convenient assembly mechanism 3 consists of a positioning slot 31, a positioning block 32, a screw hole 33, and a fastening bolt 34. The surface of the cylinder fixing block 105 is provided with a screw hole 33. The surface of the screw hole 33 is threadedly connected to the fastening bolt 34. One end of the fastening bolt 34 passes through the screw hole 33 and is threadedly fastened to the surface of the slider fixing seat 101. The surface of the cylinder fixing block 105 is provided with a positioning block 32 for positioning and assembling the cylinder body 1. The surface of the slider fixing seat 101 is provided with a positioning slot 31. The surfaces of the positioning slot 31 and the positioning block 32 engage with each other.

[0026] During implementation, the cylinder fixing block 105 drives the positioning block 32 to automatically engage with the corresponding positioning slot 31. Under the engaging action of the positioning slot 31 and the positioning block 32, the cylinder body 1 is positioned and assembled. Subsequently, the user tightens the fastening bolt 34 on the surface of the screw hole 33. Under the thread engagement of the screw hole 33 and the fastening bolt 34, the cylinder body 1 and the cylinder fixing block 105 are assembled on the surface of the slider fixing seat 101. This makes the core-pulling structure easier to operate when assembling or replacing the cylinder body 1, thus realizing the function of easy assembly of the core-pulling structure.

[0027] Furthermore, such as Figure 4 , Figure 5 and Figure 6 As shown, the slider fixing seat 101 is internally equipped with a multi-core pulling mechanism 2, which consists of a wire rope body 21, a limiting screw 22, a spring 23, a wire rope adjusting block 24, a first vertebral insert 25, a second vertebral insert 26, and a third vertebral insert 27. The inner wall of the slider fixing seat 101 is provided with a wire rope adjusting block 24. The surface of the wire rope adjusting block 24 is threadedly connected to the limiting screw 22. One end of the limiting screw 22 passes through the wire rope adjusting block 24 and is threadedly fastened to the surface of the slider seat 120. A spring 23 is fitted onto the surface of the limiting screw 22, and one end of the spring 23 is fixed to the surface of the slider seat 120. All surfaces of the body 117 are equipped with wire rope bodies 21. One end of the wire rope body 21 is fixed to the surface of the wire rope adjusting block 24. The surface of the slider insert fixing block 113 is connected to the first vertebral insert 25. The surface of the first vertebral insert 25 is connected to the second vertebral insert 26. The surface of the second vertebral insert 26 is connected to the third vertebral insert 27. The first vertebral insert 25, the second vertebral insert 26 and the third vertebral insert 27 extend into the interior of the vertebral body 107. One end of the guide bar 119 extends into the interior of the slider insert fixing block 113, the first vertebral insert 25, the second vertebral insert 26 and the third vertebral insert 27.

[0028] During implementation, when the cylinder body 1 is working, it pulls the slider seat 120 to move. Since the wire rope body 21 is fixed on the wire rope adjusting block 24, and the adjusting block is fixed to the slider seat 120 together with the spring 23 using the limiting screw 22, when the slider seat 120 moves, the first vertebral insert 25, the second vertebral insert 26, and the third vertebral insert 27 move synchronously under the action of the wire rope body 21. While the slider seat 120 moves the relevant parts, the seat 117 and the guide strip 119 fixed to the surface of the seat 117 by the fastening screw 118 are stationary. Their stationary movement is determined by the stroke control rod and the stroke fixing block 109. Since the travel fixing block 109 is stuck on the positioning block 116, and the positioning block 116 is fixed on the slider fixing seat 101, the seat body 117 always maintains a certain distance from the slider seat 120 under the action of the limiting block 115. The trajectory of the spine block movement is determined by the guide bar 119. When the spine block moves into a straight line, the slider seat 120 just touches the seat body 117. At the same time, the groove on the positioning block 116 just reaches the position of the travel fixing block 109. The travel fixing block 109 moves upward and disengages from the surface of the positioning block 116. The seat body 117 moves backward together under the drive of the slider seat 120, realizing multiple core pulling to achieve the function of multiple core pulling of the core pulling structure.

[0029] Working principle: In use, first place the cylinder body 1 in the designated position, so that the cylinder body 1 drives the cylinder fixing block 105 to move to one side of the slider fixing seat 101. The cylinder fixing block 105 drives the positioning block 32 to automatically lock into the corresponding positioning slot 31. Under the locking action of the positioning slot 31 and the positioning block 32, the cylinder body 1 is positioned and assembled. Then, the user tightens the fastening bolt 34 on the surface of the screw hole 33. Under the thread engagement of the screw hole 33 and the fastening bolt 34, the cylinder body 1 and the cylinder fixing block 105 are assembled on the surface of the slider fixing seat 101. This makes it easier to operate the core-pulling structure when assembling or replacing the cylinder body 1, thus realizing the function of easy assembly of the core-pulling structure. This makes it easier for the user to assemble the cylinder body 1 on the surface of the cylinder fixing block 105 when using the core-pulling structure, making it more convenient for the user to operate when using the core-pulling structure.

[0030] Subsequently, the arc segment that cannot be demolded is divided into three vertebrae for easy assembly: the first vertebrae insert 25, the second vertebrae insert 26, and the third vertebrae insert 27. When the cylinder body 1 is working, it pulls the slider seat 120 to move. Since the wire rope body 21 is fixed on the wire rope adjusting block 24, and the adjusting block is fixed on the slider seat 120 together with the spring 23 using the limiting screw 22, when the slider seat 120 moves, the first vertebrae insert 25, the second vertebrae insert 26, and the third vertebrae insert 27 move synchronously under the action of the wire rope body 21. While the slider seat 120 moves the relevant parts, the seat body 117 and the guide strip 119 fixed to the surface of the seat body 117 by the fastening screw 118 are stationary. Their stationary movement is determined by the stroke control rod and the stroke fixing block 109. Since the stroke fixing block 109 is stuck on the positioning block 116... The positioning block 116 is fixed on the slider fixing seat 101. Under the action of the limiting block 115, the seat body 117 always maintains a certain distance from the slider seat 120. The trajectory of the spine block movement is determined by the guide bar 119. When the spine block moves into a straight line, the slider seat 120 just touches the seat body 117. At the same time, the groove on the positioning block 116 just reaches the position of the stroke fixing block 109. The stroke fixing block 109 moves upward and disengages from the surface of the positioning block 116. The seat body 117 moves backward together under the drive of the slider seat 120 to realize multiple core pulling. This realizes the function of multiple core pulling of the core pulling structure, thereby helping to reduce human intervention, speed up the production rhythm, improve the overall work efficiency, reduce unnecessary energy consumption, and minimize the wear on the mold and other equipment, extend the service life of the equipment, and finally complete the use of the multiple core pulling structure.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
