Detailed Implementation
[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments:
[0023] First Embodiment
[0024] Please see Figures 1-6 A mold for utility poles that is easy to assemble and disassemble includes a support base 1, a lower mold body 2 mounted on the support base 1, an upper mold body 3 disposed on the lower mold body 2 and mated therewith, two coaxially fixed threaded rods 12 with opposite thread directions rotatably mounted on the support base 1, each threaded rod 12 is threadedly fitted with a vertically arranged sliding frame 7, a locking wedge 18 is installed on the sliding frame 7 through a vertical elastic component, the locking wedge 18 is horizontally aligned with the edge of the upper mold body 3, half tubes 5 are fixed to the ends of both the upper mold body 3 and the lower mold body 2, the two half tubes 5 are vertically aligned, a threaded sleeve 6 is threadedly fitted to the half tube 5, an end plate 4 is fixed to the end of the threaded sleeve 6, and through holes 15 are evenly opened on the end plate 4.
[0025] In the process of producing cement utility poles using this mold, the lower mold body 2 is installed on the support base 1, and the upper mold body 3 is hoisted onto the lower mold body 2 by a gantry crane. The mold closing action is achieved by the docking of the upper mold body 3 and the lower mold body 2.
[0026] A guide rod 16 is fixed on the support base 1, which is parallel to the threaded rod 12. The sliding frame 7 has an L-shaped structure and is slidably sleeved on the guide rod 16. A screw wheel I11 is fixed at the end of the threaded rod 12. By turning the screw wheel I11, the threaded rod 12 is rotated, causing the sliding frame 7 to move toward the lower mold body 2. This allows the locking wedge block 18 to push against the upper mold body 3, thus achieving the lateral and vertical limiting effect of the upper mold body 3 and ensuring that the upper mold body 3 and the lower mold body 2 can be quickly and stably connected.
[0027] The vertical elastic component includes a guide post 26 vertically fixed on the sliding frame 7. A sleeve block 20 and an adjusting frame 23 are slidably sleeved on the guide post 26. A vertically arranged spring 24 is fixed between the adjusting frame 23 and the sleeve block 20. The spring 24 is sleeved on the guide post 26. A locking wedge 18 is fixed on the sleeve block 20. The vertical elastic component also includes a U-shaped frame 21 fixed on the sliding frame 7. A threaded post 22 is threadedly connected to the U-shaped frame 21. The bottom of the threaded post 22 is rotatably mounted on the adjusting frame 23. A screw wheel II 25 is fixed to the end of the threaded post 22.
[0028] With the above settings, rotating the screw wheel II25 can drive the threaded column 22 to rotate. At this time, the threaded column 22 drives the adjusting frame 23 to move vertically under the guidance of the guide column 26, thereby achieving the effect of adjusting the initial compression degree of the spring 24. With the elastic pushing action of the spring 24 on the locking wedge 18, the locking wedge 18 automatically adjusts and positions the upper mold body 3, and the upper mold body 3 and the lower mold body 2 are stably closed and connected.
[0029] Second Embodiment
[0030] Please see Figures 1-6 In addition to the first embodiment, the support base 1 is provided with a slot 17 for the lower mold body 2 to be engaged, the lower mold body 2 is fixed with a positioning block 10, and the support base 1 is provided with a positioning groove 19 for the positioning block 10 to be engaged.
[0031] The lower mold body 2 is adapted to the slot 17, so that the lower mold body 2 is engaged on the support base 1, and the positioning block 10 is engaged in the positioning groove 19, which has the effect of limiting the position of the lower mold body 2, preventing the lower mold body 2 from rotating during the mold closing process, effectively improving the mold closing stability and improving the mold closing efficiency of the lower mold body 2 and the upper mold body 3.
[0032] In addition, the upper mold body 3 has several bolt holes 13, and the lower mold body 2 has bolt seats 14 that correspond one-to-one with the bolt holes 13. After the lower mold body 2 and the upper mold body 3 are closed, the bolts are passed through the bolt holes 13 and connected to the bolt seats 14 to achieve a locking connection between the lower mold body 2 and the upper mold body 3. By threading the threaded sleeve 6 onto the half-pipe 5, the ends of the lower mold body 2 and the upper mold body 3 are locked. The axial steel bars in the steel cage inside the lower mold body 2 and the upper mold body 3 can pass through the through hole 15.
[0033] In addition, semi-guide rings 8 are fixed on both the lower mold body 2 and the upper mold body 3. The two semi-guide rings 8 are joined together to form a disc-shaped structure. Half-baffles 9 are fixed on both sides of the semi-guide rings 8. During the centrifugal operation, the lower mold body 2 and the upper mold body 3 after mold closing are hoisted onto the centrifuge. The centrifuge drives the semi-guide rings 8 to rotate, thereby centrifuging the cement mortar inside the lower mold body 2 and the upper mold body 3.
[0034] In summary, the lower mold body 2 and the upper mold body 3 of this utility model constitute a forming cavity for wrapping the steel cage and cement mortar. The positioning block 10 and the positioning groove 19 are engaged to stabilize and limit the lower mold body 2. With the help of the two sliding frames 7 moving closer to each other, a pair of locking wedges 18 can clamp and limit the upper mold body 3, and finally realize the automatic docking and limiting of the upper mold body 3 and the lower mold body 2, which greatly improves the efficiency and accuracy of mold closing, and makes the operation of connecting the bolt through the bolt hole 13 and the bolt seat 14 more convenient and faster.
