Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figures 1-3 The existing demolding structure of utility pole steel molds is not convenient for setting up auxiliary tools for quick demolding. In order to solve this technical problem, this embodiment discloses the following technical content; A quick demolding structure for a utility pole steel mold is provided. The upper surface of the base plate 1 has a first storage groove 2 at the middle of both the left and right ends, and a second storage groove 3 at the middle of the right side of the base plate 1. The inner front and rear ends of the second storage groove 3 are provided with connecting holes 4. The upper surface of the base plate 1 is provided with a bracket 5, and the lower surface of the bracket 5 is fixedly connected to both the left and right ends with movable slide rods 6. The movable slide rods 6 are slidably connected in the first storage groove 2. The upper inner ends of the bracket 5 are fixedly connected to hydraulic rods 7, and the output end of the hydraulic rods 7 is fixedly connected to a plug plate 8. The bottom right side of the bracket 5 is connected through a fixed block 9, and the left end of the fixed block 9 is engaged with the connecting hole 4. When demolding is required, remove all bolts from the mold, then pull the fixing block 9 out of the connecting hole 4, push the bracket 5 so that the bracket 5 carries the insert plate 8 to the middle of each mold group, then insert the fixing block 9 into the connecting hole 4 so that the left end of the fixing block 9 engages with the connecting hole 4, and fix the bracket 5 on the base plate 1. Then start the hydraulic rod 7. The output end of the hydraulic rod 7 carries the insert plate 8 to move inward. The insert plate 8 has an "L" shaped structure and the bottom end of the inner side of the insert plate 8 has a pointed structure, which allows the insert plate 8 to be inserted between the lower mold 10 and the upper mold 12. As the insert plate 8 is carried inward by the output end of the hydraulic rod 7, the upper mold 12 will be gradually moved upward by the action of the insert plate 8 until the upper mold 12 separates from the lower mold 10 and the upper mold 12 separates from the inner electric rod. After the upper mold 12 is detached from the mold and the electric rod, the electric rod can be removed from the lower mold 10 to complete the demolding. Example 2: Existing demolding structures for utility pole steel molds are not suitable for poles of varying lengths, making it inconvenient to lengthen the mold by splicing it together. Furthermore, the joints of the molds are not easily sealed to prevent leakage. Therefore, this example uses the following technical solution: Figures 1-6 As shown; The mold body is composed of a lower mold 10, an arc-shaped groove 11, an upper mold 12, a first connecting plate 13, through holes 14, a stabilizing bolt 15, an arc-shaped protrusion 16, an arc-shaped groove 17, a first annular locking block 18, and an annular locking groove 19. An arc-shaped groove 11 is formed in the middle of the upper surface of the lower mold 10, and the upper mold 12 is set above the lower mold 10. The outer sides of both the lower mold 10 and the upper mold 12 are fixedly connected to the first connecting plate 13. Several through holes 14 are formed at equal angles on the first connecting plate 13, and the through holes 14 penetrate through the mold. A stabilizing bolt 15 is connected to the inner right side of the lower mold 10 and the inner left side of the upper mold 12. An arc-shaped protrusion 16 is fixedly connected to both the inner left side of the lower mold 10 and the inner right side of the upper mold 12. An arc-shaped groove 17 is provided on both the inner left side of the lower mold 10 and the inner right side of the upper mold 12. The arc-shaped protrusion 16 and the arc-shaped groove 17 are engaged and connected. A first annular locking block 18 is fixedly connected to the outer front side of both the lower mold 10 and the upper mold 12. An annular locking groove 19 is provided on both the outer rear side of both the lower mold 10 and the upper mold 12.

The feeding mechanism is composed of a feeding pipe 20, a second connecting plate 21, a pressure block 22, a top plate 23 and a third storage groove 24. The feeding pipe 20 is opened at the middle of the top of the upper mold 12, and the second connecting plate 21 is fixedly connected to the outer side of the top of the feeding pipe 20. The pressure block 22 is provided on the inner side of the upper end of the feeding pipe 20. The top plate 23 is fixedly connected to the top of the feeding pipe 20 by several bolts. The third storage groove 24 is opened in the middle of the lower surface of the top plate 23. The outer side of the pressure block 22 is in contact with the inner side of the feeding pipe 20, and the top of the pressure block 22 is engaged in the third storage groove 24. The front and rear sides of the mold body are provided with sealing plates 25, and the outer front side of the sealing plate 25 is fixedly connected with a second annular locking block 26. Based on the length of the utility pole, prepare lower molds 10 and upper molds 12 of appropriate length. First, attach several lower molds 10 together from front to back and install them on the base plate 1. Use bolts to pass through the through holes 14 on the first connecting plate 13 outside the retaining bolts 15 to fix and connect the several lower molds 10 together. When connecting several lower molds 10, the first annular locking block 18 on the front side of the rear lower mold 10 engages with the annular locking groove 19 on the rear side of the front lower mold 10 to prevent material leakage at the connection point of the lower molds 10. After assembling the lower molds 10, install the upper mold 12 onto the lower molds 10 and place the upper mold 12 on the upper surface of the lower molds 10. The connection point between the lower molds 10 and the upper mold 12 is provided with an arc-shaped protrusion 16 and an arc-shaped groove 17 to prevent material leakage from the connection point of the lower molds 10 and the upper mold 12. Use retaining bolts 15 to secure the left and right sides of the top of the lower mold 10 and the left side of the bottom of the upper mold 12. The first connecting plates 13 on both sides are fixedly connected together, so that the lower mold 10 and the upper mold 12 can be tightly connected together. The arc-shaped grooves 11 on the lower mold 10 and the upper mold 12 are closed together to form a circular structure. The front and rear sides of the upper mold 12 are also provided with the first annular locking block 18 and the annular locking groove 19, which can be spliced ​​together with the lower mold 10 to prevent leakage. After assembling the lower mold 10 and the upper mold 12, the front and rear ends of the lower mold 10 and the upper mold 12 need to be sealed. The sealing plate 25 is attached to the front and rear sides of the lower mold 10 and the upper mold 12. The sealing plate 25 is of two types: the second annular locking block 26 and the corresponding groove are provided on the front and rear sides, so that the sealing plate 25 can be tightly attached to the front and rear sides of the lower mold 10 and the upper mold 12 to prevent material leakage. The sealing plate 25 is fixedly connected to the lower mold 10 and the upper mold 12 with the stabilizing bolts 15 to complete the splicing and assembly of the entire mold. After assembling the mold, remove the bolts on the top plate 23, remove the top plate 23 from the feed pipe 20, remove the pressure block 22 inside the feed pipe 20, pour material into the mold through the feed pipe 20, and after pouring, install the pressure block 22 back into the feed pipe 20. The lower surface of the pressure block 22 fits against the outer side of the arc groove 11 in the upper mold 12. Finally, place the top plate 23 on the second connecting plate 21 and fix the top plate 23 to the feed pipe 20 with bolts. After the material in the mold solidifies, remove the mold and remove the pole from the mold.
