[0003] In the traditional manufacturing process of utility poles, the mold casting method is often used. First, the steel bars inserted inside are bundled and fixed to form an internal steel bar cage. The steel bar cage is placed in the mold, the mold is closed and both ends are sealed, and then concrete is poured into the inside. During the pouring process, the mold is vibrated to remove internal air bubbles. When pouring concrete, a ring groove is opened on the mold, an outer baffle is placed inside the ring groove, an inner baffle is placed on the inner side of the mold, the steel bars on the steel bar cage are installed on the inner baffle, and fixed mold heads are installed at both ends of the mold to prevent, thus completing the casting of the utility pole.
[0004] In view of the above related technologies, after the installation of the mold, the inner baffle, the outer baffle and the mold heads at both ends are completed, during the pouring process, the operator may have the situation that the concrete adheres to the outer baffle and the mold, resulting in difficult demolding and the end face of the demolded utility pole being relatively rough. Summary of the Utility Model
[0005] In order to improve the forming quality of pouring and facilitate the demolding after the production of utility poles, this application provides a mold for manufacturing utility poles.

After completion, the operator places it in the groove through the end where the die head assembly is not installed, and installs the die tail baffle. After the die head assembly is installed, pouring starts. After pouring is completed, the die head assembly is removed, and the disassembly between the retaining claw and the die head baffle is carried out. Compared with the original installation method of the groove and the ring edge, the operator can disassemble it relatively simply.

Detailed implementation manners
[0030] The following further describes the present application in detail with reference to all the attached drawings.
[0031] The embodiment of the present application discloses a mold for manufacturing a utility pole.
[0032] Referring to Figures 1 to 5 , a mold for manufacturing a utility pole, including an outer shell 1. There is a pouring space inside the outer shell 1, and the pouring space is arranged along the length direction of the outer shell 1. A number of retaining claws 112 are provided at both ends of the outer shell 1, and the retaining claws 112 extend towards the pouring space. A die head baffle 3 is provided on one side of the outer shell 1, and a groove 31 for fixing one end of the steel reinforcement cage 101 is provided on the other side of the outer shell 1. The die tail baffle 4 is detachably connected to the outside of the groove 31, and a die head assembly 2 for stretching the steel reinforcement cage 101 is provided on the outside of the outer shell 1. After the operator places the baffle in the pouring space, the position of the die head baffle 3 is adjusted until the die head baffle 3 abuts against the retaining claws 112, and the die head assembly 2 is fixed and connected to the internal steel reinforcement cage 101. After completion, the operator places it through the end without installing the die head assembly 2 into the groove 31, and installs the die tail baffle 4. After the die head assembly 2 is installed, pouring starts. After pouring is completed, the die head assembly 2 is removed, and the connection between the retaining claws 112 and the die head baffle 3 is disassembled. Compared with the original installation method of the groove and the ring edge, since the contact range between the die head baffle 3 and the retaining claws 112 is small, the operator can disassemble it relatively simply.
[0033] Common utility poles are ordinary utility poles and prestressed utility poles. Before the prestressed utility pole is completely solidified during pouring, it is necessary to keep stretching the internal steel bars. Therefore, in order to facilitate the operator to stretch during the pouring process of the prestressed utility pole. The die head assembly 2 includes a pull plate 23 and a main die head 21. The pull plate 23 is provided with a threaded rod 211 extending towards the main die head 21. The main die head 21 is provided with a through hole for passing through the threaded rod 211. The main die head 21 abuts against the outer shell 1, and the threaded rod 211 is sleeved with a locking sleeve 212. The pull plate 23 is used to fix the steel reinforcement cage 101 or the steel bars of the prestressed utility pole. The die head assembly 2 is fixed by tightening the locking sleeve 212. After fixation, the main die head 21 abuts against one end of the outer shell 1, the locking sleeve 212 abuts against the outside of the main die head 21, and the pull plate 23 abuts against the die head baffle 3, completing the fixation of the above components.
[0034] When demolding, it often occurs that the force between the locking sleeve 212 and the main die head 21 is relatively large, making it difficult to remove the locking sleeve 212. The die head assembly 2 further includes an auxiliary die head 22. The auxiliary die head 22 is located on the side of the main die head 21 away from the casting space. The auxiliary die head 22 is provided with a number of tensioning ejector rods 221 along its circumferential direction. The side of the tensioning ejector rod 221 away from the main die head 21 abuts against the auxiliary die head 22. The locking sleeve 212 is located on the side of the auxiliary die head 22 away from the main die head 21. The auxiliary die head 22 is provided with a relief hole. After installation, the tensioning ejector rod 221 is rotated to leave a certain space between the main die head 21 and the auxiliary die head 22, and the locking sleeve 212 abuts against the auxiliary die head 22. After pouring, the operator rotates the tensioning ejector rod 221 with a tool, so that the tensioning ejector rod 221 is separated from the main die head 21, and then it is convenient to rotate the locking sleeve 212 for demolding.
[0035] The housing 1 is divided into a lower half shell 12 and an upper half shell 11. A number of fixing screws 121 are hinged to the lower half shell 12. The rotation direction of the fixing screw 121 is perpendicular to the axial direction of the housing 1. The upper half shell 11 is provided with a fixing groove 111 for placing the fixing screw 121. The fixing screw 121 is provided with a fixing nut. By rotating the hinged fixing screw 121, placing it in the fixing groove 111, and using a tool to fix the fixing nut, the fixing between the upper half shell 11 and the lower half shell 12 is realized.
[0036] Due to the excessive length, it is necessary to limit and fix the length direction of the housing 1 to improve the casting quality. A protrusion is provided in the length direction, and a fixing ring is sleeved outside the protrusion. The connection between the fixing ring and the protrusion is detachable. Installing the fixing ring at the protrusion realizes the connection between the fixing ring and the protrusion, and then limits the axial and circumferential directions of the housing 1 through the fixing ring. In this example, the fixing ring is split into two sections, and its installation and fixation are completed by means of assembly.
[0037] To strengthen the overall strength of the mold. A number of reinforcing rib plates are provided along the length direction of the housing 1. The reinforcing rib plates can not only strengthen the strength of the housing 1, but also effectively improve the stability of casting.
[0038] Since there is less limit for the die head baffle 3 during installation, the die head baffle 3 may move during installation. To solve its movement and improve the fixing accuracy. The die head baffle 3 is provided with a positioning groove. The positioning groove is located on the side of the die head baffle 3 where it abuts against the retaining claw 112. The positioning groove is adapted to the retaining claw 112, and the positioning groove and the retaining claw 112 are in one-to-one correspondence. By positioning and limiting between the positioning groove and the retaining claw 112, it is effectively convenient for the operator to install and position the die head baffle 3 during installation, and then the movement during casting can be effectively reduced, and finally the effect of improving the casting quality is achieved.
[0039] The above are all preferred embodiments of this application, and do not limit the protection scope of this application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
